Interesting findings

[BurritaSVT]

I discovered a welded spot with two large pits on it. And I found my silcone 90 degree hose lose i could find out why my boost would not hold up. I noticed it got worse where I could only get 10 psi then I knew I had a problem I found it the d@mn hose was loose going to the Throttle body. I am curious now how long this been going on I will test it tomorrow if it holds 15 psi across the board watch out we may get another run to pick up some lost air. Wish I could have seen that before the dyno.

I take it as the coupler is after the turbo?

You said you were running 17psi peak during the run, correct? it may have come loose as a result of the runs. What style clamps are you using?

I will be joinging you with findings...I have been using the wrong bolt retainers in the upper manifold...not sure I have been getting the best seal.

I think my plug wires are also out...new nes to arrive today and...yes there is a small crack on the inlet of the IC. not sure if it is causing anything, but I'll need to go get that welded.

We'll see...it'll be a while before I can get everything done.

If that''s what it was, look out burrita! Now you may never get traction, LOL

well I am using just regular SS hose clamps I need to order the wider ones and really wrench down on them. See The guy told me on the dyno he saw it hit 18 psi once but it ping at low rpms because we haven't pulled enough timing then. It was terribly looselast night it slid so far off that the clamp was off the edge of the intercooler. But since the the hose was still relaxed on the pipe the car an fine on lower boost. But after I hammered it last night I saw it creeping down to 10 psi. I will do some full runs tonite to redline and if the car does not drop pressure or power then I may have a little more air left we will see.

This is getting soo interesting ... keep the info flowing and keep up the good work!

You need to see about getting some t-bolt clamps. those have nuts that wont back off and you can really tighten them. Just becareful not to over tighten them and collapse the pipe. Where is ur boost gauge hooked up? If your seeing it spike to 18 and fall back a little, thats not totally uncommon. it sounds like it fell off due to the runs. So definately see about some better clamps.

Here is where I am getting mine ... great price!

Also...if your intercooler inlet and outlets don't have a lip...you can band /flare out the ends a little....I did that on mine before I kept blowing the hoses off.

Gotta use tbolt clamps.

Also I made up a pressure test fitting out of PVC. Get a PVC end cap that fits in the silicone couple that the maf hooks up to and put an air fitting in the end. Clamp in place.. plug in air hose and you'll find your leaks.

Just be careful with how much pressure you use. Start low.
