im buying my old series 2 back but am looking for around 280 - 300 bhp and would like to use it for track and 1/4mile it already has adjustable tca's and toyo t1r's but i would like to know what else is going to get the power down without taking too much performance away, i am alrwady sourcing a quafe atb diff and toyo 888's as i know theese will help, Thanks

 

Taking some pressure of the tires will help, but it will become very prone to torque steering. It's not a bad idea also to map less boost for 1st and 2nd gears. But in the end it all comes to tires.

 

cool ok thanks for the advise

 

You will virtually completely irradicate torque steer with a Quaife ATB. It makes an amazing difference.

 

cool thanks
