EGT's out of control

[Mike]

I can't do that.... I made sure I had a pyro BEFORE it ever towed anything!

The DP is definitely on my to do list now!

You need a boost gauge too.

Mike,

The boost gauge went in, before the pyro did... Once I hit 9PSI, the EGT's climb quick. 10PSI is about all I can hold, without ******* the pyro.

Then you have something bad wrong going on, bone stock you should have no problems pushing 15-17 psi boost and the HIGHER your boost pressure (and RPMs) the lower your EGT's will be.

I would begin looking for boost leaks, you should be able to make more than 10psi without running into egt trouble

I'd say you got a problem going on cause my 96 with programer on high rarely reaches 1200 degrees pulling 10-12k pounds. I'm wondering if the ebpv is stuck partially shut?

What he said.

You have leaks someplace.

I'm planning on replacing the boots, that go to the plenums(?) I guess that's what they are called... BTW: what seals them to the heads?

 

[trackspeeder]

The boots to the plenums are the leakers in most cases. They get soaked with oil and crap. Then start to crack.

There is a gasket that seals the plenum to the head.

It's the boots I need, but can't find.. I wonder if I could just match something up somewhere...

I did manage to find and order the gaskets I need, for the compressor outlet to Y-Pipe connection...

I found all the hoses I need and got them changed. My boost numbers went from 3PSI at 70MPH on the interstate, to 5-6PSI on the same stretch of road. I've been able to max the boost out at 16-17PSI, when I put my foot in it.

I also changed out the crushed DP, in favor of a 3" DP. I haven't towed with it yet, but was only able to go a bit above 1200* while climbing a steep hill, about 2 miles uphill.

I already have the 6637 intake and the cat delete, so the only possible thing left to do (That I can think of) is gut the EBPV.

does this thing have a chip in it?

Nope.... Sure don't

 

[Russ]

Shouldn't have to gut the EBPV on a stock PSD. If EGT's are still high, you have other problems.

I got a better feel for it today... Coming home from work...

I can get it just past 1200*, but really have to work it.



I'll see how it goes, next time I tow with it!

you should have noticed a bit more power too.....
