Got owned tonight

mightywhitey5269 · 11-18-2009, 10:36 PM

So I slid my #6 plate halfway forward and cranked the starwheel all the way. With my mods below I raced a buddy of mine tonight in a bone stock 94 ctd auto dually 2wd. It only has a small air filter and cut off exhaust. He beat me from a red light. Im clueless of why. Im guessin its because of my boost pressure (12-14). Any ideas? Possibly timing?

12 to 14 is really low, Stock I had a little over 20 to 25. I would defiantly look for a boost leak.

get a spray bottle of soapy water, and spray it on all the boost hoses and look for bubbles. Also, he could just have a better auto than you, since the auto is what either plants or sucks up all the power.

get a 4" PVC cap and a 4" hump hose, put a schrader valve in the cap and pressurize the front of the turbo... this will pressurize the entire boost tract and makes it easy to find leaks

Thanks for the replys. I dont think its the auto, because he has 180xxx on his and completely original. I got a new tc and it shifts firm in all gears. Im goin to try and do those test on it this weekend

try plugging your waste gate under the turbo. I am getting 42psi.

Generally boost leaks are around the boots, but you could have a hole in the intercooler.

lower gears than him plus the extra weight of a transfer case and front axle?
