- VTII SS Gen3
Hey guys!
I've recently had a fair bit of work done on my VTII SS gen3...
Heads
Cam 224/234
OTRCAI
Highflow Cats
Springs + Pushrods
Extractors + Twin 3 inch system
VX Manifold + 80mm throttle body
Mafless tune + rev limiter up 500rpm
3000rpm converter
And a rebuilt t700 with stage 2 shift kit and cooling system going in tomorrow.
Diff ratio's are still standard.
Now with that all out of the way... Onto the question...
On the dyno she made: (@ Wheels)
271.5 kW @ 5502rpm
1186.1 Nm @4191rpm
BUT....
My understanding of a dyno pull is that it should be done in 3rd gear, as close to 1-1 ratio as possible(I believe 3rd in the T700 is exactly 1-1?) ... The pulls that produced those figures were done in 2nd gear (1.63 - 1 ratio apparently)...
How will this effect the numbers? Is it what you would call a *True* reading?
Would I then be wrong to say "My car has 271.5kW @ the wheels"??
I've an ever growing mistrust of my mechanic, even these figures aren't up to what was promised before the mighty dollar was handed over... I would appreciate any answers you guys may have...
Cheers!
