View Full Version : No power with sr20

04-05-2008, 10:46 PM
My car is at a shop getting tuned right now and it isn't making any power with sard 850cc inejectors at 55% duty cycle at 10 psi.

s15 sr20det
hks 256/256 step 1's
precision gt28rs .70 ar inlet/ .86 ar outlet
JE forged pistons, stock comp
walbro fuel pump
sard 850cc's
haltech e8

On the dyno he can only get it to hit barely 175hp on the dyno. Does anyone know anything to check for? I've searched and can't really find anything. Any help would be appreciated.

maybe you're losing compression haha..bad valves/ check timing....

timing is good, haven't done a compression test yet, anything else that could cause this, hopefully just something electrical?
