HP Figures For The NSX

[BlueNSX]

:dunno: Can anybody Direct me to or tell me the HP/RPM figures and Gear Ratios's

For : 3.0L NSX
: 3.0L NSX-R
: 3.2L NSX
: 3.2L NSX-R


Many Thanks

[dan the man]

3.0ltr NSX is quoted @ 270bhp @ 7100 RPM
NSX-R of same year NA1 is the same quoted BUT probably more.

I stand corrected, cheers James. :)

[TheSebringOne]

3.0 NA1 270 BHP
3.0 NA1 Type R is 280 bhp, blue printed engine & weight reduction
3.2 NA2 1997 to 2001 is 290 bhp
3.2 NA2 02+ 2002 onwards, estimated at least 300 or even 310-315 bhp?
3.2 NA2 02+ Type R same above, blue printed engine & weight reduction?

Honda UK only quoted 276 bhp maximum under Japanese car makers gentleman's agreement, but in the US its officially 290 bhp

HTH :)

3.0 NA1 270 BHP

3.2 NA2 1994 to 2001/2002 is 290 bhp
3.2 NA2 02+ 2002 onwards, estimated at least 300 or even 310-315 bhp?
3.2 NA2 02+ Type R same above, blue printed engine & weight reduction?

Do you mean 3.2 NA2 1997 to 2001?

BTW Until proven otherwise I will not believe the rumors of the extra horses for the 02 plus.

I think the weight loss might have helped the 02 plus, but dont believe that all had NSX-R engines.

[TheSebringOne]

Sorry Ary, now corrected! When the 02+ came out it was quicker by nearly a second over the standing mile time and apparently not much changed over the 97 to 01 pop ups!

[AR]

apparently not much changed over the 97 to 01 pop ups!

The 02 is lighter and has better aerodynamics.

That is where I they get the extra speed from.

Cheers,

AR

The 02+ rumour has been quashed. I got 285 bhp at SRR, and although they reckon their adjusted numbers are lower than Power Engineering, there is little chance mine is a 300bhp car

Officially Honda claim 0.1 seconds quicker to 125 for the 02 facelift. I think the rumour of the power hike was started by the optimised press car

[Rob_Fenn]

I believe Detlef's NSX-R engine achieved 330bhp, but i believe that was with a full exhaust system at the least.

Rob,

It would be good to get a dyno plot of this and find out what type of dyno the run was done on.

[bazza]

My NA1-R with Mugen headers and a GruppeM style exhaust made 293bhp with standard intake, ECU and engine.:)

If you check the Procar thread on Prime, I believe Detlef has posted his dyno read outs

Was that with the my intake mod or the original one?

Glad to know I was not crazy when it felt that quick!

Sorry all. That was with the scientific Ary intake mod :laugh::laugh:

[BlueNSX]

Is it wise to spend £ on a 3.0L or save £ and purchase a 02+
my milage is only 31000 mi.

Thanks

[dan the man]

think biggest thing on the NA1 is the headers, so restictive and naff they hold a few horses away.

But if it were meupgrade the brakes and tires for same effect on track etc.. and support bars here and there

[AR]

It all pepends what you are after really. For me it makes sense having spent so much on mine, for others it might be different.

It would appear to be tuned?

I can't see any NSX having more than 300bhp as standard

http://www.nsxprime.com/forums/showthread.php?t=32686

Even the NA2 Type R got hammered by the CSL in the 0-100-0 Autocar test

[Rob_Fenn]

Yep, the spec (for 312bhp, not 330bhp as i thought):

The Procar NSX was powered with:
Standard NA1 3.0l engine year '92 and 13.000 miles
and some performance parts:
Fujitsubo GT headers
ARC titanium test pipes
Taitec GT lightweight exhaust
Procar cf cone air intake tube
Procar cf airbox with APEXI airfilter
Procar cf fender scoop
MUGEN ECU

Interesting that he had another 1000rpm to go though, would be interested to see what it would have got.

[TheSebringOne]

I don't think the CSL will cream a Type R 02+ to 60mph or 100mph, but in the braking its better, so the 0-100 & 100 to 0 will be slightly quicker. Even though its a heavier car at 1385kg, but with 355bhp V 290bhp and 1270kg?

BMW M3 CSL:
0-30mph: 1.91mph
0-60mph: 4.62secs
0-100mph: 10.82secs

Honda NSX Type-R:
0-30mph: 1.94mph
0-60mph: 4.91secs
0-100mph: 11.41secs


I would reckon the NSX would be closer than this if it had 330bhp. With ~300bhp these numbers seem about right.

Performance really seems to depend on the car and also how run-in and loosened up it is. As I've posted before, my car (3.2 manual) was owned by the Group Chairman of Autocar/Haymarket and Autocar tested it back in 1998/99.

With 5000 miles on the clock it did 5.5s to 60mph and 12s to 100mph, but after 20,000 miles it did 5s to 60mph and 11.5s to 100mph. This was published in the Dec 2nd Autocar.

More surprisingly, Autocar tested it again later (1999) and it did 4.8s to 60mph and 10.9s to 100mph - see the back of an old Autocar - Roadtest section (the new ones only show results for the 3.0 from 1991).

Subjectively since having the exhaust and intake changed it feels quicker still.

Happy and healthy 2008 to one and all!

Matt,

I have the book

http://www.amazon.co.uk/Acura-Honda-NSX-Performance-Portfolio-1989-99/dp/1855204282/ref=sr_1_15?ie=UTF8&s=books&qid=1199089556&sr=8-15

where it talks about the Dec 2nd road test.
I also have the 2002 Autocar issue where the LBB 02 car did 4.8 0-60 and 10.9 to 100.

Which issue did the the 97 car do 10.9 to 100 as I couldn't find it in my collection of Autocars?

[NoelWatson]

Slightly off topic but was checking out the BMW 330 touring and noticed that they now come with 272 bhp. Pretty impressive with a redline of only 7000rpm.

[TheSebringOne]

Matt, since your car quickens with mileage and time, you should be in the low 3s by now given the mileage and time since the mags test! :D

Noel, off the thread too, does'nt the 335I now has around 300 bhp! :(

And I think that 300bhp is quite easy to increase!

http://wheeltalk.fancal.net/?p=725

Emissions of the 330i are only around 170g compared to our 290. Amazing how engine technology has advanced.

[Senninha]

And I think that 300bhp is quite easy to increase!............. Amazing how engine technology has advanced.
But would you really want to in real world conditions??

Those of us who do 'use' the potential of the NSX have stories of how we have stayed with or even left behind more powerful machinery, be that some of Munich's finest or indeed 500hp Italian stallions. This suggests that HP is not king and that many things contribute to a quick car.

IMO, all the new high HP engines are great for Clarkson style headlines, but clearly with the changing engine technology comes a changing society that wants to be cossetted by air bags and other safety features, computers and more. All these items are adding weight, so the important number in any engine that can be of real world benefit, is surely the torque figures.

Point a case is my daily driver. An Accord Tourer with the diesel engine. I was recently engaged in a spirited drive across some interesting B roads in the Grantham area. The 2.2 is not a particularly high torque engine, but, it has a relatively flat and wide power band. Despite some interesting lines from a driver in need of some training and a better understanding of his cars ability, there was rarely more than a few cars length between me and this particular Boxter. Being able to remain in the torque curve, using less gear changes and looking further ahead made this an interesting reality check when thinking about further engine upgrades.

To this end, any future performance mods will be to the chassis or the aerodynamics of the NSX. I would love to find those extra few ponies to have my own headline at 300bhp, but for now, and on todays roads, I'll settle for 289 and invest in some further driver training as this really does make a difference!

Paul, Do you find the Chassis Bars have improved your handling as You have a T-TOP. And am I correct in assuming these are for the front only (Upper and Lower)? Would it not be corect to fit something similar to the rear to provide the correct ballance ?

Who would you recomend to do mechanical work on your (performance upgrades against servicing)

Thanks

I'm in the process of fitting the bars this week. Only chassis mods so far is the front ARB from the NA2 NSX-R. This made a small but still noticeable difference. F to R balance is important and it will be interesting to see if the bars, added to the ARB make the rear feel loose. If they do then I guess I'll be installing the Zinardi rear bar to tightne the rear. My guess from the homework I've done is that this wont be necessary as I have the later rear bar already, which should work fine with this set-up.

Depends where you are in the UK and what you are contemplating doing. A lot of the mods on my NSX I have completed myself or with other owners. Over and above that then I would consider using either Nortons or Plans if I felt the job was to involved or needed specialised equipment to complete.

I'll let you know when I next have the NSX on its wheels and out for a drive.

Totally agree that the NSX has enought power for the road, the only time I felt it was lacking was when at VMax, but within a week of returning realised that it was more than quick enough on increasingly congested UK roads.
I too plan to do some driver training - thinking of Cadence, unless you can recommend otherwise?

OK,

If people are truly interested in good driver training for the road, I can get something organised.

My Brother in Law, an ex Marine sargeant, runs his own business, Skills & Techniques, teaching advanced driving techniques.

He developed his skills driving for the diplomatic service. If you are familiar with the Civic TypeR forum, he is held in high esteem by many who have experienced his teaching as one of Honda's MAC instructors.

I will speak to him in the week to understand what could be set up if we are looking for a group session. IIRC, he and his business partner can train upto 6 drivers as a max session for a day. Alternatively, it is possible to arrange 121 training in your own vehicle.

If this is of interest, let me know. I'll kick off a seperate thread with the options that are possible.

I have the ARB brace off the NSXR fitted and noticed a difference right away, still to fit the radiator brace as got to LH brackets and not on of each etc..

its just more taught and direct when u turn

How are the Chassis Bars???

coming back on topic,are then any figures out there for 02+ other than Noels car? I havn't seen any graphs on here.

I found this hidden away on prime, The 97-01 engine and 02+ engine is the same and there were no changes made to it from what info I can find, unless the exhaust has a lot to do with hp and torque I think this graph should be the same for a 97 or an 05.
Please do post if you think this is correct or incorrect

I think you are correct. I researched this a while ago on Prime. I seem to remember there being some emissions work around the time of the facelift - I will see if I can find it.

[duncan]

All jolly good, but by the way, whose measurement of horse power are we using? SAE, DIN, CUNA or the latest incarnation PS
SAE[USA] is 10-25% above net power as defined by DIN[Germany], CUNA[Italy] is 5-10% above DIN. They all measure a different set of circumstances.
