Thanks mate.
The 4.3 should be fine will be pulling close to 7500in 5th. I run with the 4.6 in it a few years back and had to raise rev limit to 8000 was hitting 7800 just before the kink and again just before the chase was making less power but still pulling close to 230km/h. I cant remember 100 % if I ever run with the 4.11 at supersprint. I had run at oran park, wakefield and local drags. The day I raced against your GTR and lunched the clutch I was using the 4.375
I cant remember what we set the rev limit to with the new engine I think from memory around 8000 I can change it on the day if you like.lll Bring the laptop along.Just remember to bring the cable.
Cheers Andrew
