that turbo is still gonna whistle like a hair dryer.

Am I the only one that likes the sound of a vgt?

You sure aren't, I love mine.

What are the concerns with the 68mm?

da94broncodude · Feb 23, 2012

having a powermax now im excited to hear your reviews as lance said cheaper to mod the pmax to 68

amarillo250 · Feb 23, 2012

can you tell me the advantage from a 68 to a stock Pmax, please. I'm running my Pmax now for a while and it is real hot with 180/75% over stock. Does the 68 with the batmo reduce egt a lot?

That exact question cannot be answered, as Brant and Garrett are testing them out first before anyone else. The normal cast wheeled 68mm Powermax outflows the stock one substantially, with stock like spool up. They are a fun turbocharger, thats for sure.

the 68 out flows a standard pmax by 10 lbs/min. with the billet probably a tadd more.

Cool deal. You going to go to Matt for the tuning, or meeting him somewhere? Let me know, I need to get up with him and re-tune mine. I'll join ya.

is 10 lbs/min significant? I'm bout ready to go non vgt but if the 68 would be a noticeable difference over the pmax, I'd be interested.

The plan is to take it to him in CS when it's done and let him do his thing. The more the merrier man!

RCD is gonna snd me a tune so I will have something driveable right away til I can get the truck to Matt.

Everything else being equal...for every 10 lbs/min you should gain 10 hp.

For driveability.. I would say 68 hands down

so assuming that's correct, would it even be worth going up from my pmax? Would there be more to gain from a nonvgt...powerwise?

In your case I think the 68mm would probably work well, and would be a big difference from the powermax... I still feel like it will have that loss of breath feeling up top only because its a VGT, but i couldn't say i've never ridden in one, I'd like to though. I just cant stand the vgt whistle anymore LOL ! If anyone going to rudys has one i'd like to go for a ride.

Supposedly the batmowheel will enhance top end though right?
