Want to see what a bad y-pipe flex section will do to an 11 psi manual 5th gen?

Yeah, I tried the 5 threads left without the hex nut and it was too tight, BOV didn't go off. With 5 threads left with the hex nut seem right, BOV goes off. Thanks for the suggestion btw. I'll be sure to listen from now on.

The real test is to get on the dyno so you can see for yourself. Engine/intake/exhaust and road noise makes it very hard to tell if the BOV is leaking or not... but you can always look at the boost gauge when you are near redline. Multi-task!

It could be that since now you're 5 speed, it feels just as fast your 4speed auto cuz of the difference in gear ratios...

Having different gear ratios will not affect power if we're dynoing at 1:1.

I'm not talking about the dyno numbers. I'm talking about why daily driving feels the same to you now even though you're making less power than before....

I don't have money to BUY anything, that's why you are going to GIVE me the SC. For posterity of course!

I think I beat him to it hehe. Here is a screen shot of the info since I didn't feel like typing it out http://www.geocities.com/nismo87se/1...o_vs_5spd.JPG. . Basically the 5spd gets owned, from a roll it only gets worse.

Thanks! I knew gearing isn't an issue, but had no data to back it up.

Take off the cat and look at the flex section. I haven't fixed mine yet.

hey Kev,

Sorry I couldn't get to it over the weekend. The woman had me all tied up (not literally ) doing misc stuff so Ari beat me anyways

Oh well. Are you planning on redynoing with the fixed flex section + SC before you take it off? If so I'll just wait for those numbers (no sense in duplicating Ari's work). If not I'll just run it based on what you should have been putting down (320-340ish)

No problem, Steve. I'm redynoing again when the flex gets fixed. Projected date of when the SC comes off is October 12, 2002... so the dyno will be before that.
