i must have bad luck. i have had 3 quit on me. but even my aem gauge has been sent back once

 

When I had my boost issues, it would go past 17 normally.
Now, it just looks like my wastegate is opening at 15.
It caused me to over boost after I rebuilt my turbo last weekend, map and maf maxed if I did a pull.
So my tuner suggested I connect my stock gauge by its side. Comparing the two, they both follow each other thru boost/vac until about 15.
The glow shift is mechanical. Possible the hose is slightly kinked somewhere?

 

The vac t fitting it came with had a little brass fitting with a small hole in the top(to gauge). Is it better to run a normal t fitting

 

Mine came with a plastic T-fitting.

 

mine did to, but the top of the plastic t fitting had a small brass piece in it that had a small hole.

 

Oh, I don't remember if mine did or not

 

i managed to finally in the topic on it.
Supposedly this small piece helps reduce noise to the boost gauge.

My current system is:
-intake manifold vac, t off to wastegate, stright hose to another t for boost gauge, final hose stright to BOV.
Im going to try moving the boost refenence for the gauge before the wastegate

 

Yes. That little restrictor pull helps keep the gauge movements smooth. In 2nd gear my car builds boost faster than the gauge can move

 

So I do have a sudden slight leak somewhere up top of exhaust causing lean at idle. Happened after a day of tuning

But heres a quick video.
What do you guys think I'm making for power?

 

I would like to know as well

 

Ok guys and gals I had an exhaust mani gasket fail me awhile back been contemplating which one I should go with, any suggestions please it would help the decision making lol

 

Copper

 

Remflex gaskets are great.

I don't know if I should run more boost! I'm only at 18 in the video.
Don't wanna blow it upppp, still runs good compression. 120k miles tho.
I can't really gauge what a safe number is. Any suggestions?

 

What turbo?

Its a cheapo version that I rebuilt with Garrett internals

 

I wouldn't call that necessarily a cheapo if it's made with garret parts. At 18 I would ballpark you at 340.

 

Ya it was an ebay looking turbo I got in a used kit on here.
When i blew the oil seal I decided to use a garrett kit to rebuild.
I was thinking that range too! Do you know what you're running for power?

I have been thinking about running more boost but idk how safe it would be

 

Nailed it ^^^^

 

Realistically I would guess around 375. Give or take maybe 15 or so. Just a rough guess.
Another member on here made 339 on 19psi with pump gas and the smaller ar version of my turbo; don't know anything about the tune but would guess fairly conservitave. I'm running 20.5-21 and a pretty good amount of timing thanks to the corn. And this sob hits hard lol. Love it.

 

What are compressor and turbine #s of yours?

Glow shift works now! Pulled it out of pod, looked at it, put it back in. Now boosts fine past 15 ?

 

gonna finish stripping block tomorrow and then its off to Mr. B for sleeves, the Black Widow revival has begun

 

How long has it been down? As long as I've been a member I don't remember seeing it on the street

 

It died in mid april 2012, so itll be right at 2 years once it is finally up and going again

 

55mm compressor, 57mm turbine, 0.63ar
They are awesome. I've helped install several sets.

 

I need help im new here I just bought me a xobalt ss and has oil (runny peanut butter) in the water reservoir what to do
