NSX-R factory spec's 12.4 1/4 mile, 4.4 0-60, 175 top end. Stradale factory spec 12.1 1/4 mile, 4.0 0-60, 186 top end. My NSX 0-60 4.1 (on board CPU), 1/4 mile 12.3, have been to 180 and it had a little more. My Stradale is a bit faster than stock should be sub 4.0 0-60, high 11's, 198 top end with the mods I have.
The NSX-R and mine, although lower on power, have things done that cannot be seen in HP figures alone. Such as gearing, less rotating mass (wheels & brakes), six speed Vs F1.
Another thing is usable HP. My NSX does not spin at all when I leave the line. The Stradale is very hard to get out of the hole, especially with the F1 tranny. You have to do a race assist start on the Stradale. You hold the brake, press a button, rev to desired RPM, let go of button, hold RPM, release brake, then the clutch drops. This is the only way to get a good start or you will burn up the clutch. Thing is you get tire spin no matter how hard you try. After 90-100 the Stradale walks the dog on my NSX but on a tight track with no real long straight's the NSX has a fighting chance!
Lets make it clear I know the NSX is still in the game! That is why I started this thread. A moded NSX can still kick A$$.
Hope this helps clear it up.
