Turbo

[centerfitt]

Can any one tell me what the size is on the stock turbo for the 2001 7.3? When I bought the truck, I was told that its an upgrade turbo and its hitting about 18-20lbs of boost @ WOT.

The search function is your friend. If I knew the answer, I would help you out. If you check out the 7.3 forums you will find 99% of the answers to your questions.

I hit 20lbs on my stock turbo (no tunes) at WOT. This is standard.

1.0 compressor side, .84 a/r exhaust side..boost sounds about right.

thanks guys. How well will the truck take it if I turn up the boost another 5 or 10lbs or os that not a smart idea? If I can do it, how would i go about doing it? I know on a gas engine you can add a boost controller.

buy a chip/programmer and it will add more fuel and increase your boost.
some good guys that sell custom chips for these trucks are
tony wildman, beans, gearhead, php, dp tuner.

also with elevated boost levels you may experience "surge"
this puts a lot of stress on the turbine and shaft. so if you get surge
you can either get the a wicked wheel 1 or wicked wheel 2, dieselsite sells these
or a 4 inch ported compressor housing ats or usa. riffraff sells these

if you want to know what surge sounds like type it in on youtube or even on here.

yeah I am already in contact with DPtuner for there unit. the one I am looking at comes with a 7.5 LCD screen and I would be able to keep an eye on my pids and stuff. Keeps me from having to plug my scanner up lol

Does the INFINITY come already "tuned" for the truck, also?

[centerfitt]

from my understanding it does. i think I have to send my vin down to the guys and have all that stuff done
