I have 2 questions.

I`m not seeing more than 30psi with my turbo. Its a 62/65/12. My mods are in my sig. I thought these wastegates were good for 40psi. Any info?

Second part. My cruising egts are 780-900 degrees. I have a 4" db and 4" exhaust. Thats with the adr. on pl02.

 

you probably have a boost leak somewhere

 

Do you have injectors? Check for leaks.

 

No, stock injectors. The only thing I removed was the coupling from the turbo to the intercooler. Could my other couplings possibly fail, or do I need to bump up to bigger inkectors. Even with my adrenalin on pl08 it`ll light rather quick, but still will only hit 30psi. Would being -below zero cause this?

 

if i clamp the vacuum line fron the wastegate to the housing it`ll boost over 30psi. im lost...

 

Sometimes the wastegates arent set to what they say. You can adjust it by turning the actuator rod. I dont remember the direction 100% but i think you turn it so it get longer to raise boost.

 

Ok, then how do you get at it? Do I hav eto take the turbo off again?

 

You want to make the rod shorter to increase boost.

 

x2 what Tate said.

 

Ahh i was close, its been awhile. I did them off the truck with shop air befor. I never tried to squeeze my and tools in there while its bolted up.

 

your not putting that much fuel into it. i was only seeing 30 with my edge box then i did injectors and the watermeth now i see 42 all day.

 

You don't have the fuel to see over 30 pounds. Most of the HTT chargers are set at 42 psi. That's plenty of boost for stock head bolts and gaskets. Put some sticks in and it will go up.

 

So when I clamp the wastegate line shut, i see 40psi... So if I put bigger injectors in it`ll build more boost? I can hit 30psi without a problem right now.

 

What Tune are you running on your Adrenaline. With my buddy's truck 01 built Auto Htt 62/65/12 stock injectors With one of the comp tunes it will hit 40psi easy

 

More fuel = more boost. Thats why I asked if you had injectors. Thats a little bit big of a turbo for stock injectors to push over 30psi.
