Recently purchased a used UPP twin turbo fender mount kit for my c6. I purchased it used which came with the 57mm turbos, their website claims they will support 1000hp. But after holding one of the turbos in my hand im thinking that its highly unlikely. I may be regretting the decision to go from my f1r procharger kit to this turbo kit. Not that this is a bad kit, im just not sure how it's going to hold up to my build.
Im shooting for 1000rwhp. My car is a 05 base 6spd, 408 stroker, dart 250cc heads, 1000hp+ fuel system, etc etc.
So is there anyone out there that has made 1000hp with the 57's, i do plan on upgrading but for now im going to run these little things for a while.

Not a UPP kit, but made 1100+ on 57mm turbos time and time again.

As long as you've got supporting mods and enough octane to keep it from detonating while still maintaining some degree of timing, you should be just fine. 1000whp is on the upper end of what those turbos can flow, and they're not the most efficient at that point, but they will do it. I've personally pulled 550+whp out of a single one. Most people are under the impression that you need giant T4 turbos to make 600+ whp, and that simply isn't the case.

The turbos themselves look rather small, but that's because we originally elected to go with the T04B housings vs the T04E. So rather than look at the turbo size overall, look solely at the impeller blade, or even the relation of the impeller to the housing. It's alot larger than it seems....

v8 people love to over turbo motors in my experience. Every wants twin 66s+ when all they land up making is 800-1000 and a nice pair of 56mm, or if you really want bigger 61s will do that all day with ease. Made 1150rwhp the other day with some twin billet 57 BWs on a LSX 427 setup.

Well I'm going to put them to the test. I suppose i can just run my boost line from turbo to the top of the wastegate to keep them from opening. I don't use a boost controller and not sure what springs id need.

I'll bet it hit like a nitrous car too. almost no lag with small twins.

Yah, the mid range torque was crazy. 1000+ftlbs from 3000-5500.

exactly why I'll be doing 62's on a 427. tark tark tark
