I have a 2001 Cummins and have a Hy35 stock turbo and wondering what kind of boost you guys are putting out in your 98 to 02 auto. trucks. I am putting out 37psi which I think is good for a Hy35.

 

Thats alot for a HY. 35psi is the choke point. I was at 32si when I had mine.

I see 55psi now.

 

Much more then 32PSI and your just making a lot of hot air. What kind of EGT are you seeing?

 

I have my HX wastegate set for 34psi max. Nice and safe.

 

I have a 64/71/14 phat shaft now. EGT's low 600 going down the highway 1200 full tilt.

 

My highest egt is 1400 but I do need a Aurora 4000 for my truck and I think I would get better mpg and a little more horsepower.

What would make my truck put out that much boost. I havn't touch the turbo at all.

 

Well I just have the HX35W on my truck with the wastegate hose clamped shut. At full throttle I see 30 psi and around 1,000 - 1,100 on the Pyro

 

But the Hy35 in the 2001 has the wastegate built in the turbo so you can't clamp the hose off.

 

They're talkin bout the hose from the wastegate to the turbo-to-intercooler boot.

Here's a pic

 

Not the best but it's dark out so blah

Anyways, it's the hose going from the gate to the turbo itself, that's what they mean when they say "clamped hose". In the picture, it's the blue-ish hose that you can barely see under the intake tube.
