I Would absolutely love to see this. 189km 2300 rpm 4th gear for me damn speed limiter. Forget about mods and know that the speed limiter in most of the vq 3.5’s is 143mph and thats a electronic fuel cut, not a redlining or drag limited issue. Could be the 3.5’s your racing are autos???. My fuel cut is 189km. But I’d love to see the outcome from say a standing launch or a 20-30k roll.
Oh BTW Any reason you have a turbo timer on a N.A. Car???
