We are proud to announce we have successfully fitted the CTSC kit to one of our customer's car.

Silver Surfer have asked if we can get his NSX charged back in December 2009, he came down to our shop and check out what we could possibly done to his car and got the CTSC kit ordered.

CT-engineering originally quoted us 4 weeks for the kits to gets here but due to the delay caused by the snow all over the world, it ended up took them 8 weeks to get the kit to us.

So anyway to cut the story short here is the whole process -

First we got the car up to check the overall condition, we performed a leakdown test, injectors check up and cleaning and general check up to make sure the engine is still in good condition to take up the extra power -

Have to say this is a very high quality well built kit, the whole fitting process took us less than 2 days (fitting the clutch actually took longer).

We are putting the car on the dyno tomorrow to adjust the fuel regulator for the best A/F and will keep you guys update with the result!

Is that a Red FMU as in Hi Boost?

I did it differently, took a couple of hours to change gearbox, engine oil and plugs, then one day to fit it.

Might as well get rid of the TCS now as it will only play up.

Well done,

I don't really understand what you mean?

The Fuel Pressure Regulators have been red for a long time. *The color does not have anything to do with the internal parts of any regulator. *They're all red.

So there is nothing "hi-boost" about the kit you have.

Thanks Ary.

Do you have a picture of your dash with all the extra gauges as I am not sure where to put then without looking to 'Chav'.
What other gauges do you recommend? I was initially thinking an audio or light warning as I am not sure I'll be looking at the gauges whilst I am pushing it.

I can set you up a Defi Fuel pressure gauge and also oil temp and pressure gauge, but you don't really need those if you are only using the car on the road.

All Defi gague comes with warning light and a very annoying 'Beep' at warning so you won't need to look into it.

Or you can have a similar gauge setup like we have done on Mo's car, you can check it out on his when I see you this weekend.

They are not all red, for years CT used the Blue Vortech FMU for low boost and the red for Hi Boost.

When was the last time his fuel filter was changed? Since the CTSC takes the feed from there. It makes A LOT of sense to get a new fuel filter in place. I hope you changed the washers ( new ones with a fuel filter ) to avoid leakeage.

C'mon guys is only like £15.00 for a bloody filter and not really any extra labour.

We actually found the Japanese car fuel filter is pretty good quality, in the pass 8 years, I have done countless of races and work on countless of cars. We have never ever seen a car have problem with old fuel filter even with high power output.

Most common is standard high mileage Evo, we have done loads of this with just remap, changing exhaust, intake, turbo and other mods, pushing 450-500bhp on a high mileage engine and never had a problem with fuel filters. Also loads of other high power Honda and Nissan GTR...etc.

On my own race car running the same fuel filter for the pass 6 years and we have never change it and we win quite alot of races with it.

On this Supercharge NSX, we are only getting 100bhp more power which is a walk in the park for a 3 litre engine and only probably using 40% more fuel than stock map, I believe even fuel filter is the last thing we need to worry about.

Anyway we got a new one in now, going to see the car on the dyno right now. Will keep you update

How lean?

A good idea since you are already there is to inspect and if needed change the fuel line that goes from the tank to the filter.

How lean was it?

Starting fuel pressure?

It was holding at 13.5-1 from 4000 rpm until 7500, we stopped it there as we didn't want to Hurt the engine, From 2000-3500 was good spot on at 12 tho. We
have even adjusted the FPR and made no different after speaking to CT we are pretty sure the fuel pump is abit tired.

It pulls 360bhp at 7000rpm tho so when we sort out the fueling we should see good 380-400bhp mark.

Hi Paul,

Ive have now got braided lines and new racing brake fluids. I've been told the brake calipers are OK and I've a set of Mugen Disks which will go on once the current drilled and grooved set starts to wear out.
I am going to change the pads first to see if this will improve the feel with the above adjustments.

My Falken 452's still have loads of tread left.....

With headers and exhaust at 6 PSI you will see around 380 to 390 on a 3.0 don't go too lean for the sake of power.

You should bring that down and fit it in the car before we put it on the dyno again, A/F ratio might change a little with different exhaust as it gives different back pressure.

You might be better to put the cats back on with the Larini exhaust. A free flowing back box on stock cats will make better power than the standard back box on text pipes.

Gruppe M or Ary V1 as in Mutleys is the way to go for exhaust. :) Made for SC cars so it will not blow out the baffles. larini did not listen to me when building the exhaust from my NA1R mule and...

As far as the box most people have had really good results with the OEm and the UNI filter. I am back to the paper one as the other ones let too much crap in, is not like you need an extra 3BHP with an SC. :)

The 97 headers are almost as good as aftermarket only hur by the scavenging effect, but then again with FI is not like you would hurt for a couple of BHP.

I hope you enjoy it as much as I do mine and remember to get the AFR gauge ASAP as you never know when anything might happen and next thing you know is like CILIT BANG and the engine is GONE. LOL

Should I:
The procar scoop and airbox do look good.....how much crap does it really let through or is it theoretical? Is this a real concern or should I just run it and see?

Also

1. Put the cats back on and put the Larini back box on... or
2. Leave the test pipes on and leave the OEM back box on...or
3. Leave the test pipes on and put the Larini BB on...or
4. Put the Cats back on with the OEM BB.?

Option 3 would be the best if you find the noise levels acceptable.

Procar Scoop OEM Box and filter is what I would go for. I am sure you can get good £££ for the Procar box from any of the NA bretheren. You'll be amase how much more fuel you'll go through. ( Where is the evil Smiley! )

I think AR meant the non panel style paper filters e.g. K&N, Pipercross etc, let more crap in. The airbox and scoop shouldn't be a problem in this respect.

As AR says option 3 if you don't find it too noisy. My preference would probably be 1, 3, 2, 4

As you're only really concerned about running too weak (lean), if you hook up a warning lamp rather than a guage you won't have to accommodate the bulk of an aftermarket gauge.

Almost anything is possible if you have the money. Simple physics....ask more of something, it won't last as long.

100 hp is achieved with fairly low boost (7-8lbs?) so not too bad at all.

An example from my cosworth days: It was reckoned that a standard 205bhp cosworth engine was good for 130k miles (runs about 7lbs boost). Phase 1 chipped to 270 bhp (about 15 lbs boost) would reduce the expected engine life to 80k miles.

mmmmmmmm 100bhp extra no prob been runnin on 400 for 2 years and i hit the limiter a few times limiter is set to 8400. 150 mmmm i would not want to chance it id take it to 125 extra but thats it build your engine then your talkin 600 no worries

For monitoring AFR, ...Do any of you guys know of any aftermarket warning lamp/siren which comes without the gauge as I am not sure I am happy with the look of a stand alone gauge on the OEM look....plus when I am driving hard, the gauge is usually less likely to be looked at whereas a warning lamp/siren/buzzer which catches your attention would be more effective for me?

Don't think something like that exists as to let this functon, several data would have to be compared at the same time by the unit like:
-engine load
-rpm
-A/F
Only when putting these all together and comparing these data real time, a warning signal could be calculated.
There are however engine computers that measure A/F together with lots of other data and can datalog. When reading this out, you could see afterwards why your engine blew up :rolleyes::):)

A/F units can be had with round gauges (with a sliding scale and/or digital readout, but also with small square digital readout display if you feel this to look better in your interior.

rsevo6
13-03-2010, 10:44 AM
Just kidding, in last message described manner with datalogging, you could possibly see a dangerous situation before engine damage occurs, but you would have to check regularly.
I prefer to have a gauge so during accelleration I can have a quick look how the A/F is.

Afr gauge won't give you any warning, because when you lift off everytime then the gauge will read lean.

You need a fuel pressure gauge that will give you warning when the fuel pressure is low.

Jim SC is a great option but as soon as I find out if Amo's low comp built goes well I will be doing a low comp built and going Turbo, so there might be a nice used one in the future.

I've not read through it but I'm sure it is capable of monitoring everything you could ever possibly want. It may not be your taste but how about this installed in an OEM Nav Pod?

http://www.scienceofspeed.com/products/engine_performance_products/NSX/HKS_CAMP2/

Exactly my point made earlier.
This unit can display lots of sensor readings and can make an alarm if some limit is exceeded (I have a similar unit in one of my cars).
However with A/F this is of no use as it goes from rich to lean all the time. It is depending on engine load and revs (even intake temps influence things) when a certain A/F number is dangerous or not, so different data have to be compared at the same time and calculated to be able to make an alarm on A/F.
And this CANNOT be done by any unit that I know of.....

Better, no way, as GruppeM is designed for SC applications. My Exhaust is an improvement over the gruppe M and made in the UK with a lifetime warranty.

The GT 5.1 is just playing with pipes. Bel Canto what a load of cobblers. I urged an ex NSX parts vendors to ask Taita to get some more done. he offered to make them and put anyones name on them.

Sorry chap, what does made for SC applications even mean?

Playing with pipes is what you have to do to get a 90 degree V6 to "scream". The exhaust pulse frequency just doesn't work to produce this high pitched sound so you have to add some extra pulses into the mix by way of tuned length bypasses and resonant chambers.

Nothing wrong with it, whether made in Japan, Taiwan or Nepal or if labelled a GT Rom 5.1, Taitec FN09, Bel Canto or indeed Bellendc*nto, the noise is to die for :)

Exactly... and remember it's not just a peak figure, you've got a lot more power everywhere in the rev range. If you overlay the before and after power/torque curves you should find that the car now exceeds the old peak power by about 5.5K revs with power still climbing strongly. The car will feel much more muscular :)

Top end power is not important, have a look to his Torque Curve and you will see the gain is actually on the torque not the top end power. Torque is always more important than top end power as you don't really use them.

No idling problem at all as well with the lightweight flywheel, the rev now climb much quicker and also you get really nice respond from the throttle.

As I understand it Amo's is a very different type of SC (Basch Boost, Paxton) which is gives a differant power/torque profile i.e. more suited to top end power than mid range.

Remember power and torque have a fixed relationship to each other, the variable component is revs.

Dudes....I have taken the first step in the SC NSX world and thought I share my first impression of this pricy outlay.
I have done 60miles of mixed driving today. :D
The most noticable thing in the increase in power is as Markc has indicated, is the increase in Torque as the car seems to accelerate in any gear from 1.5K onwards. This suits me fine being a lazy gear shifter and on the motorway, overtaking in 5th (top gear) from 60+mph is now so much easier without the need to downshift. The acceleration is very linear and the down side is that there is not much noticable VTEC kick!
The noise has also changed expectedly as I am now noticing very little VTEC induction noise and more of the SC whine which I am use to from my other 3 SC/turbo cars. The bark from the Larini exhaust coupled with the SC whine does make it interesting....not quite sure which I like best! Through Dartford tunnel, the sound was fantastico!!! (had my window down and stuck it into 3rd gear!). I will let Paul (Senninha) chip in as I am slightly tone deaf so an alternative opinion would be helpful.
The lightened flywheel does indeed allow the revs to shoot up with the slightest of throttle but drops like stone when I change gears. This meant I need to let the clutch up quicker to catch the revs...( I will need to learn to do Heel-Toe!)
Generally with the incease torque, I am needing to press the throttle pedal less hard and not as long so hopefully it will not do the consumption figures an injustice,,,I will let you know how much mileage I will get out of this full tank in due course.

Conclusion...Am I happy..So far :thumbsup::proud:
I am due to be in NW London way (Near ACE Cafe) next week so be more than happy to meet up with any current owners for them to hear/feel/see the SC in action for themselves so PM me if interested.

Dixon, most well used NSX are punching above their weight. It was 276 stock and quite a few have dynoed over that. I have had two, one an NSX-R that delivered over 295 on a humble dyno.

The intake is just hype, the best one for NA and CTSC is the OEM box and filter.

The main diffrence is the headers and the exhaust good combos can release a lot of what the OEM system was constricting:

In most markets the 3.0Ltr cars were quoted as producing 270hp as standard.

Our attempt to get a good selection of NSXs on a dyno in the same place at the same time so as to normalise some existing dyno readings saw the standard 3.0Ltr cars making a touch less than less that (average 262hp), possibly due to their age as Dixon says. See table here... http://www.nsxcb.co.uk/index.php?categoryid=26

As AR says both 3.0Ltr and 3.2Ltr cars respond well to having a decent exhaust fitted and the 3.0Ltrs also respond well having their restrictive cast iron exhaust manifolds replaced with tubular ones a.k.a "headers" in Americanese.

SS's car already had "headers" and a better exhaust as well as being de-cat'ed so, if everything else was as it should be, should have been making around 285-290hp prior to having the SC fitted.

AR, what's made you want to move away from the SC?

More power really, nearly 380 is great fun but you soon get used to it. Then you want more and since if I want to go high boost reliably I will need to get a the very least an AEM FIC to sort out the fueling. If I am doing that I might as well get a Turbo, since the main reasons I see for a CTSC is that it is a DIY system that does not require mapping. The hardest part is changing the plugs, and that only because my hands are too big. :)

A Turbo is to very simple to install, and the mapping, well I am still waiting to find a reliable mapper close by. Might end up using Amo's mate.

My goal is 450 BHP on a standard engine IC and MEth cooled for the near future.

For now the SC is great and quicker than a R8 V8, but a Big T is Murcielago territory. :)

As per Luke's thread on big brakes, the number of pots/piston is somewhat irrelevant. Your biggest challenge is getting sufficiently sized discs in the front wheels.

Hi Mark,
We did have a bit of fun on the roads initially with me following. From my car, I managed to keep up with Paul fairly easily without needing to change from 3rd to 2nd much on the twisties and also only needed to keep the revs generally between 3000-6500. Much of the route was down B roads with lots of bends and therefore unable to make good comparison on overtaking abilities. When I took over as lead for the later part of the run, my TCS and Engine light problems which stopped me from giving it the full beans.
Coupled with my driving skill is probably inferior to Paul...Difficult to compare.
I think if it was on the straights, the SC would probably gradually catch up and overtake rather than blow the NA 3.2 away.
Pauls car is a very healthy NA 3.2 with better condition brakes and suspension than my SC and this will also limit the comparison on this run.

SS

Prior to the SC...Pauls' car will gradually pull away on the straight bits in the past!

Senninha
24-03-2010, 06:34 PM
Hi Mark,

As covered elsewhere there is some fine tuning required for the SC install. Having followed and listened to Kare's NSX it did certainly sound as though the TCS was cutting in from time to time. I think investigations ar under way to make the adjustments needed.

When it was running smoothly there was virtually nothing between the two cars. We both took turns to lead/follow as we developed our route. Both reported similar instances of needing to back off as we closed on each other over mixed A&B roads. What we didn't have the option to do was pull side by side comparison or swap cars.

Once all is well we will be out again and complete the evaluation and report back on 3.0SC vs 3.2NA.

Regards, Paul

24-03-2010, 08:00 PM
Interesting.

In theory the SC car, with significantly more power throughout the rev range, should run and hide. I guess it shows that +/- 50hp doesn't make that much difference on the public road and why hot hatches are so effective on B roads. That would also explain why your friend with the R8 doesn't disappear over the horizon.

I suspect a descent straight(away) will see the SC power advantage really tell. I look forward to seeing it in the flesh and perhaps even experiencing it from the passenger seat at some point this year :)

Hi Mark,

As covered elsewhere there is some fine tuning required for the SC install.
Regards, Paul

Or... :)

There is basically no tuning on a base CTSC other than adjusting the RRFPR

Hence why I got myself an datalogging AFR and burned several gallons of VPower up an down my roads with several resets of the ECU etc on several different fuel pressures and now is all a A1.

Once again I will confirm that flat on the straights the SC or one like mine, will outpace the V8 R8.

I used to like the front of the R8 and the 3/4 from the top. I comented here when it first came out that the paper time figures were not better than my NA1R. After witnessing how the V8R8 perform in the flesh, I could bring myself to own one.

Interesting.

In theory the SC car, with significantly more power throughout the rev range, should run and hide. I guess it shows that +/- 50hp doesn't make that much difference on the public road and why hot hatches are so effective on B roads. That would also explain why your friend with the R8 doesn't disappear over the horizon.

It will be good to get these two out again and find ourselves that decent straight to pull side by side ... or not depending on results.

What it did show on Sunday was what I've often said (and probably sounding like a broken record), that in the real world and on the roads we love to drive, ie challenging A&B roads (coz anyone can go fast in a straight line), it will require at least 100hp+ and a bucket load more torque to put significant daylight between two NSX.

I'm really looking forward to the SC being on song for further 'evaluation' and its a good excuse for another drive out.

And if its a little warmer next time I might just bolt on the 17's and sticky rubber to even things up a bit :)

I've no idea what the RRFPR is but the rest of it sounds like fine tuning to me ;)

I went a bit NSX Prime on you LOL. It is a raising rate fuel pressure regulator or the big red thing in the pictures.

I guess if that is tuning then I am a fine tuner and NSX specialist...NOT. ( Borat Joke )

Is that the same thing that you also referred to as an FMU in the pics at the start of this thread? What does FMU stand for, maybe Fuel Management Unit? Don't you just hate the American penchant for acronyms :)

It was said earlier that the replacement Comptech unit (FMU/Pressure Regulator) is pre-set, I guess to match the new fuel requirement. Have you fitted a different one from the one supplied with the kit?

PM me your location or contact details and I be more than happy to let you experience it from the passenger and the drivers seat in late spring/early summer. ;):)

Mark the rate is preset but you can adjust the initial pressure, hence the usefulness of the fuel pressure gauge. Still dont know how anyone would do it without it, unless by guessing and dynoing.

OK. Obviously it's good practice to check the initial pressure is correct and to spec but shouldn't this be preset correctly to match the rest of the kit?

From what you were saying any problems with fuel pressure would manifest themselves at high fuel requirements i.e. high revs and W.O.T, where the raising rate would be increasing the fuel pressure(?), how does setting the initial rate help this?

Mark if we search for this on the FI section of prime is a never ending story. Some people start with xx pressure and they are OK across the board, others end up lean, there are little tricks to get the RRFPR or FMU to get rich quicker and hold it a bit. I think the fuel pump and the injectors have a lot to say in this as well as the car compensating according to your driving style.

Just of interest. SoS doesn't have the kit on their website anymore.
Did you get the latest version? The Lysholm unit? The Autorotor was the one before.

I have the Autorotor kit.....New Autorotor unit replaces Lysholm/Whipple unit, provides 10-15% More Horsepower.
It looks nicer too!!

AR, thanks for the link, I had this in mind while writting my post and was interested in what blower Silver Surver received in the end of 2009.

Shad wrote in the thread on 12/2008 (#1):
Hi Guys,
I thought I would post a couple pictures of the new CT Supercharger we are in the final stages of testing for them. The kit is going back to the Lysholm brand of charger but the newer design (1600AX) from the original Comptech kits (1600AR). Yes, it is a little smaller than the Autorotor unit but will not have the pinging trouble that some of you have run into. In our testing on a 3.0 liter NSX that had an Autorotor unit at the same boost levels both blowers made the same HP and TQ. We will be testing it on a 3.2 liter very soon. New kits should be shipping early next year and it will have CARB #. Cheers, Shad

and later (#26):
Hi Guys,
Yes, as Joe pointed out the changes/redesign of the Comptech/CT kit over the years has happened because of the supply of blowers. Getting blower from the guys in Sweden (both Lysholm & Autorotor) has been very difficult, just ask Whipple (original Lysholm importer).
