Oh man, I found my boost leak!

Went to dyno and had a couple of runs and every afc setting we tried, it would give the same a/f.

I have only been seeing about 5-6 lbs of boost and have been hearing a "screaming" noise. I thought that it was a belt slippage problem, but it isnt.

we hooked up a compressor to the charge piping and fed some air through it to determine if there was a boost leak and, viola! its coming out of the adapter that fits my IAT sensor into my AWAC.

I know now why I am running so rich and only made a 13.7 run two weeks ago.

I just need some epoxy to seal it up, anyone have any suggestions? Looking for something that will work at engine temps and wont melt the plastic housing.

I was also thinking about sealing over the epoxy with some silicone.

Thoughts?

Oh, and its a V2 with a 3.33" pulley

 

Get someone too weld it again, or maybe orange stuff.

 

it wasnt welded on in the first place.

i'm off to napa to go and see what sort of form-a-gasket, sealant and epoxy that they have

what is orange stuff?

 

They use it on exhuast leaks. and around gaskets to seal leaks.

 

Wow - 13.7 on 231whp?

That's a pretty amazing run.

By my calculations you should be at about 14.3-14.5 on a good run with only that much power.

 

ill see if i30tmiked has our timeslip.

we ran each other at byron

when i was manually shifting, accidentally popped it into N out of 2nd and then shifted 2 third and went 13.7

 

wow and it was an auto too

 

I'm not saying you're lying, I'm just saying that's amazing!

I was at 273hp and 245tq when I was Auto and pulled a 14.7 as my best time. Granted, with a heavy stereo in the trunk and a malfunctioning MEVI....but still!

 

no, i was wrong ian, you were right.

it was 14.7

sorry

i fixed the boost leak last nite with that orange stuff. Its high temp rtv silicone sealer.

it looked to be holding up well this morning

im going to put another coat of it on tonite

 

OK - that makesm ore sense. Thought there was something wrong with me there for a sec. :gaptooth:

 

Woohoo! That makes me feel better about my car because I ran a 14.5 best on 5psi

 

I was like WTF!? You did not run any 13.7.......at least not when I was there. Hahahaha...I am not going to lie for you Steve

 

yeah, I ran a 14.8 with 204whp and 218tq...
