What would be the biggest turbo i could run at 25psi on pump? with the turbo still being efficient? Im thinking if im already going to get lag, why not jyst go for max power on pump!

 

Well if you are thinking like that, go for the 61mm.

 

Correct if I'm wrong, but isn't 350whp pretty low for an FP Green? I've seen some Evo IX making that much with the stock turbo tune with 93 oct.

 

I think it is pretty low compared to the figures guys are achieving here on pump and no meth. Thats why I wondering what is missing from my setup?

Is it worth changing cams to Cosworth ? or 280's? How much gain would i really get with a Green at 24-25psi?

Can someone also explain a meth kit? How would i go about running this? Would i have a second map on the Motec and flick a switch? What happens if you run out of meth? are there automatic cut offs etc?
Is this all I would need? http://shop.slowmotionmotorsports.co...ction_Kit.html
