Kevin, I've added the 3.0ltr with 6spd 'box graph to my earlier post for anyone who can't get to the spreadsheet.
I can't see why a RR wouldn't measure revs, it's soo easy why wouldn't you?
It could of course be done by microphone (knowing the number of cylinders, revs can be calculated from the pitch) or maybe even by exhaust pulses with the probe they put in the exhaust, SRR must do this??
I read up about the Dyno Dynamics machine on their website but it doesn't go into if or how it captures revs... http://www.dyno.com.au/dyno/controller
I pass SRR everyday on the way to work and dropped in on an open day they did in conjunction with Pistonheads earlier this year, but you can't drive right into the Qinetic site where they're based without going through main gate security so it's a bit of a fuss.
I'd love to do a dyno run with you one eveningWhere are you based? (PM if you'd rather)
Cheers
Mark
