Didnt realise it was UK heads, correct I would leave it where it is then and just keep practising your changes

 

theres no wonder your hitting the limiter if its only set at 7450.it wants to be atleast 8000rpm.i had mine set at 8000 on my old sti8 with standered heads and it was revved to that a hell of a lot of times and there was never any valve issues with mine.

 

Stock valvetrain Arf?

 

yep love nitrous we fit that. use the WON kit, running a mild kit on my racing puma....but she is getting a new engine in a few weeks with 250 bhp and 25bhp nitrous, she will be sweet at 1000kgs and around 280 bhp

 

Going to see if the rev limit can be increased when JGM maps the car in Jan. 8k limit in 1st gear would be perfect.

Only if 6 speed throw was like V3 sti 5 speed throw....

 

How would it launch if you set L/C limit to 4k in place of 5 gives you 1000 rpm more to play with?

 

yes mate.totally standered heads.

 

Post 21 has your answer.

 

Best way, I could rev mine to 8.5k but Simon's advice was no point revving that far just causing extra wear and tear unless you're trying for a 1/4 time. I will be mapping at SRR in Jan too for nos and c16 fuel

 

Ye there is no point revving that far, I just want a slighly higher limit in 1st. The rest of the gears are ok.

Maybe we might bump into each other, samosas all round mate

 

Change gear quicker, 1.7bar isn't that bad but if your going to constatly bounce it off the limiter I see you needing a new valvetrain soon.
