Intake plenums.....
I have blown the intercooler boots, spyder boots etc. and found by cleaning them and tightening the clamps carefully solved the problem.
Now the other day there was a "soft" pop as I was making boost. Not the usual loud noise when a boot goes.
I checked it all out and re did a few clamps. Thinking I had it taken care of I drove again to only find it is still leaking. It is able to put 10psi on the gauge but sounds like a major leak.
A little research has me looking at the intake plenums next. I will build a leak tester and am sure to find the big swoosh.
What have you guys done to keep the intake plenums sealed up? I am stock I believe with a e99 spyder.... If that helps.

You might have crushed the plenums under boost, and the boot isn't sealing with the plenum right. I read that the updated plenums work better with the e99 spyder.

*Will not fit 94-Early 99 with stock turbo, or with 8 bolt 94-96 heads.
So does that mean we have to switch over to 97 heads?
They were found in the SD section, but under application year, there was 94.5-97
So I'm a little confused.

If it does.. then the SD plenum will work on it, but not with the stock/E99 turbo setups. In order for OBS/E99 trucks to run 3" riffraff plenums (as far as I know), you gotta either have a T4 setup/equivalent, or have a super duty setup with taller pedestal, otherwise the compressor housing bumps the plenum.

Some of the older OBS heads were an 8 bolt design, apparently some made it on to 96's, but my 96 has a 10 bolt plenum. You'll have to take a look at your truck and determine if each plenum has 8 or 10 holes for bolts in it.

Sooner than later would be good. We are running the last few of this product so we would have to do it now or in 6-8 months.
