Welll, I am just here to say something...
My fren has a std GTR.. He ran constant 11.94 @ 114/113MPH.
3" front , stock Dump pipe. 4" cat back.
Blitz Twin Entry Intercooler
ARC Airbox
17psi boost.
255 street tyres on 18" rims.
With wider tyres say 275 he will get better traction.. but there expensive:)
Which is why i think that time of 11.7 is not impressive. Mind you its still got std ecu.
He is going to get Power FC and a custom dump pipe setup with intercooler water spray, he is aiming for 11.7 @ 116mph.
Will keep youse up to date.
