Hello,
I am wondering how i see people talking about turning up boost to 17psi on their CT20's yet no one had specified whether they changed spark plug gap nor retarded timing at all......So i turnt up my boost to 17 psi and was looking to see what happens.....sure enough i lost power on hitting my boost mark and saw leaning out on my gauges. Anyone else had this problem? So i wanna know what plug gap the stock motor 17 psi users have also how much to draw on the timing...if that will help Just as a starting point. o, i doubt it is fuel.....at idle my car shows 30 psi and while driving it has maybe 35-37 psi higher than pressure (aka 5psi boost = 40-42 psi fuel....10 psi boost = 45-47 psi fuel) This post has been edited by Island_Racer: May 11, 2013 - 10:50 AM |

your best bet in this case would be to put it post IC, pre TB, using a meth/water mix, with a 5 or 7gph nozzle.
i can almost garantee that with that setup, you will be able to run 18+psi, without having to do anything to the stock timing map. -------------------- Former Team 5SFTE pro member ;)

So ill scrap the idea to go pre turbo and post ic and go just post ic...i'll let you guys know what performance changes occur when i get to a dyno again...
