$20 Stock WGA Spring Upgrade

[Back-n-Black]

It is not advised to run without a heat shield as the radiant heat from the turbo can melt the plastic by the window wipers, melt plug wires, melt the coolant over flow, and so forth. Believe me if i could it would have one on it. Our turbos get hella hot. I have seen mine glow 4 or 5 times bright orange. lol

Yep my buddy lit a smoke of the turbo once after some hard pulls. I have heard back from one person who says he is only holding 15 to redline. Still a big improvement over stock hold to 11-12. I am wondering if the cold Alaska air still (10-40 degrees right now) is helping with the boost. I cannot tell you whats going on. I do have hard pipes and have done leak checks. I have every measure in place to prevent boost leaks. Also note I am using an EBC now an APexi avc-r which I just got working. Man this EBC rocks. Its nice to be able to control boost for speed and gear I am in!!

I figured that since when I do a little racing, it looks like a little devil is dancing under my heat shield . The first time my wife saw it she thought that my car was going to melt .

Correct me if I am wrong but is it the friction from the turbo compressing air that causes the high temp in the exhaust manifold with the glow orange look? That is what I explain to her.

I've got an idea turbosetch, I'm gonna try and put a bleed in the line to lessen the spike and hopefully be able to hold more boost. We'll see.

[tURBOsetch]

Ok.

On the glowing. Its air friction or resistence. The turbo is so small its very restrictive on the exhaust side. Thats why we are adding these heavy springs to these WGA's. The back back presure forces the waste gate flapper open due to the restrictions and working the turbo wheel.

[tURBOsetch]

IDEA!!!

Ok some one try this. Leave the stock spring in the WGA and put the PTP spring in the middle with the stock spring. That should hold it up better as well.

[Garrett@FTP-Racing]

^^^^I like the way you think. Maybe i'll try this.

[tURBOsetch]

Yep just keep in mind anything to redline over 18psi is gonna be hard as hell on the turbo and hot as hell. We are over spinning this turbines already. Damn I hate spelling.

This is why we have cut the scroll area down on the stock manifold. It cuts the heat to where the manifold never glows bright red and the intake temps drop 20 to 50 degrees.

it's a law of phyisics..............ANYTIME you compress air it will get hot!

[tURBOsetch]

Thats true. So PTP what will one of your moded stock turbos do for restrictions now?? What are the benefits. I have heard alot about the cliped turbos but I just though it wasn't worth it.

[will_halle]

nice find man...a couple questions though.
how are your lines run, can you do this with my setup (link in my sig)?
what about the fuel cut?

oh yea i'm s0.

Will adding this spring to the stock wastegate help with boost on my stage 2 if I run it on the stock black line?

[tURBOsetch]

Should hold boost better to redline.

[blair_t]

How much more boost would it hold because I'm holding 15psi with the stage 2 wastegate?
