238/100% with 38r

Can a set of 238cc/100% be detuned to run with a 38r and be pmr friendly?

Pmrs are hit or miss, I lost mine at 300hp. Most will say go for it but if thats what you want to do be ready for failure.. Good luck, I say dont chance it.

I ran 300/100 hybrids on the stock turbo for months in my 550 and it drove great. I now have a 38R in it and it tows very heavy and very hard very often without issue.

Flat to the floor at any GCVW it will not exceed 1200 degrees worse case and it's putting out enough power that I have melted another ZF6 and scorched the fluid in the dana 135. I would estimate that it is between 250 and 350rwhp.

Point is, you can run whatever injector on whatever turbo you want if you simply tune it accordingly. You could run 400/400's with NO turbo and be just fine if you wanted. Might only make 130hp, but it could be made to run like a top if you wanted.

Pocket is running 250/200's and 38r on PMR's with no issues towing at high altitude.

I have PMR's and i'd do it in a heartbeat, but the only one who'd be tuning it would be Bill Cohron(PHP)

Bills tunes are great, thats what I ran. Pmrs in the 7.3 are junk

I ran 200 hybrids with a 38r and ts tuned by swamps and lost the block at 1200 rpm courtesy of an errant or misplaced PMR LOL

This will be my exact setup as of Saturday, getting live tuned and hopefully on the dyno too.

Can it be done ..yes but unless your planing on switching to forged rods why..

38r..not the best..just doesn't move the air needed on the top end like other turbo's like a modded H2e..plus its a throw-a-way turbo. IMO best for stock to stage 1's.

This was my exact same set up and it worked well for 20k mile. Spoke to Dave and out to Swamps it went. Now it is really fun to drive. If your going to live on the edge with PMR's be ready to fix it when the time comes.

me too...except the dyno part. ill look to meet you there...where are you located?

Fl Stroker.... Yes it is a great setup... I put probalb 30 to 35k on the truck after stepping to this set up... Didnt mean to seem as if it was a bad idea... The errant rod was jus somthin that could happen... Im sure alot of factors came into play for the catastrophe lol

99-Resurrection · Oct 20, 2011

Here is a picture of the escape hatch my rod decide to use... somewhat led to believe by the destruction it was a piston/rod failure both... Both sides of pan and block were breached couple times... sorry picture is sideways

Fl Stroker · Oct 20, 2011

It was not ment in a bad way. My rod also went and cracked the block. PMR's are a crap shoot either way you look at it once you add extra stress to them.

I'm in the Millersburg area, north of Harrisburg. Hoping to dyno, give me something to start with #'s wise. I'll be there Saturday bright and early. :thumbsup:

Man I am sorry to hear that. How do you use/drive the truck? I hate to hear any time someone throws a rod.

Well didn't get to dyno because my boots just wouldn't stay on for the live tuning, but now with double clamps on them they seem to be staying now with 35lbs + (need a new gauge now) I'm gonna say I love this setup. The streetability in all my settings is downright amazing, completely different truck and the 38R doesn't have a problem keeping everything clean with the sweet tuning I had done.
