Belts slipping...barely making 5psi.

after many many hours of street tuning, I think I got it about where I want it. After I finally got it to hold 9psi of boost, I completely re-tuned it. runs a LOT better.

how is your car on a cold start? i had aem on my jrsc and it idled bad. i switched to hondata and ran much better. you should be able to make more power with a proper tune

it's fine. all about how you tune the warm up enrichment table and start extra vs temp table...

yea. I had my fun. I kinda figured it'd happen...learned to tune on that engine. what can I expect? it was fun while it lasted though. time for me to grow up and start tryin to save my money

Does this mean your engine blew up?

jonbar87 · 11-15-2009, 09:51 PM

not yet, but i can tell it's on it's way out. I'm still driving it around but don't have the blower on.

Well I finally got a chance to do a compression test tonight after work...the results were worse than I thought lol. I don't really care at this point, but was surprised that they were THIS low:
Piston 1

Piston 2

Piston 3

Piston 4

they were so incredibly low that I thought the tester had to be wrong...but right after we got done with mine we did my buddies s2k and his came out 235 237 240 240....so I knew that the tester wasn't bad and that my compression was just really that low lol. The only difference was with his we actually warmed the engine up before we tested(vs mine being plum cold). I don't know how much of a difference that makes, but either way that's way too low, warm or cold.
