Best turbo for hypermax?

[mx_racer428]

im trying ti find a good turbo to run with my hypermax 190s, right now i have a precision 6765 turbo with billet wheel and bar bearing center thats a 67mm inducer and a 65mm exducer and running a .91 ceramic coated exhaust housing. i am seeing very very high EGT's (seen 1800 not even hooked to the sled) and see 40+ psi of boost. any tips and pointers would be help. thanks guys

some people like the powermax turbo running 190's... or a 64mm non VGT turbo would suit those injectors well

Why, may I ask are you running that charger on the truck? What are your goals, or what did you build the truck for? With a turbo like that, certainly not daily driving? There is a definite science to mating a charger to a specific use.

i was more or less forced to use my current turbo. i work at a diesel shop for parts and the turbo i have now is what he got me. there is a reason i am not asking him about parts any more. i built this truck to be able to drive every day but also be competive at sled pulls. (mostly farm pulls). the truck pulls well but i really think my my current turbo isnt the way to go. precision also asked me why i was running that turbo.. another thing is i have been looking around and i have yet to see anyone running a precistion turbo on a 6.0. i want to run a proven, reliable set up.

I know of a 6.0 that is running a precision turbo.

I would go with a 64mm turbo for 190s.

Empire out of Dubuque Iowa deals in precision turbos. Nothing wrong with them. The charger you've got I would imagine would do well for sled pulling, but won't be worth a crap for daily driving. That A/R is huge and it's got a small exhaust wheel so it's suited for high RPM load and will flow a lot of air there for pulling. But I'll bet it doesn't even light until around 2500?

Check out somewhere in the neighborhood of a 64mm inducer, 71 mm wheel exhaust with a .76 A/R housing. You could go bigger on the exhaust housing with the addition of a diverter valve provided your exhaust housing is split. Disclaimer: This is just an idea of a starting point. You need to talk to someone that deals and works with non VGT turbos regularly and get an idea of which direction you want to go before you pull the trigger on anything. I don't consider myself an expert, I just have a somewhat informed opinion.

You might get it to light with a divider valve if you dont want to get a new turbo. There is some good reviews from the trucks that are running them. I dont think anyone has tried it with a 67 single tho. It just a thought. I would still recommend a smaller turbo.

I do know of guys running 225s with a 66mm as a daily driver just fine. Its hot and smoky but nothing someone cant handle.

im sure it would be a great sled puller but if im getting 1800 egts just on the street i can only think what it would pull when im hooked? same thing with boost. if i can pull 40+ with out a big load on it, it will have t pull well over 40 hooked to a sled, and its rated for 40psi max. right now this turbo is a bear to drive around with. 70mph smoke coming out the stack withthe cruse on with about 5 pounds of boost. thanks for all the help guys

I would think the high egts would be from not spooling is this correct? When are you haveing the 1800*? It should work better when it's hooked to the sled because it would make the turbo work and flow more air.

[mx_racer428]

You could be right on that. when i have seen the 1800 is when i was on the power but not maxed out. it was still pulling pretty hard.
