FordGuy100 One "kid" on another site was telling everybody that he was going to fab a turbo onto his motor, turn it 4500rpm's, and push close to 30psi till it blew up.

I would have so payed the money to drive there to watch

Jarrod B heres your idi with too much boost......

FordGuy100 Anything above 12psi out of a stock turbo kit is super heating the air, and you wont see any gains in performance. More than likely you will see a decrease.

A lot of guys are referring to there powerstrokes. This is an IDI. Our compression is way higher than yours, we cant run that much boost.

DieselDude92 What about a 2001 7.3 Powerstroke? I'm putting out 30-35 PSI max with stock turbo, is that too high?

4everlearning My buddy has a 6.9 thats running an aftermarket Turbo and he keeps it down to about 17psi he used to have it up at 22 but it spit the headgaskets out the side at that pressure.

pinkersc My 2001 with the power pack system maxes at 22 psi. Never get more tham 950 on the egt. This is at 2800 RPM's towing up a hill. Have the billet converter also and exhaust brake and trans-lock.

I have a dyno report on a factory turbo with a better exhaust and air intake, I will look it up and post it tomarro. I can tell you my '94 is a pullin dude!!!!! I have owned every diesel Ford has put in a pick-up and this old truck is right up their with my 7.3 Powerstrokes and it out-pulls my '08 6.4 by 3-8 mph on every hill in overdrive where the 6.4 downshifts. I am super impressed! This truck really came alive when I put a new turbo-back exhaust, Hypertech air intake, and turned the pump up half a turn and it has almost 294,000 miles on it!! Definately one of the very best trucks I have ever owned. Take a look at my garage gallery to see some of the loads I have been hauling with it (most of these loads are going to NM form AZ and another load back the other way). I doubt the boys at Ford knew that this little F250 would be pulling a 40' flatbed loaded to hilt 14 years later! Thanks for all the input guys!

No dyno but my Banks gauge that came with the sidewinder stops at 15psi and I can peg that at 15 if I get on the gas
