Compressor map for TO3 Garrett with TO4e compressor wheel

Does anyone have this map?

I don't believe that maps for wheels in non-native housings are out there.

When I first modified this turbo others told me it would work. You said it should be helpful towards 3oo + hp. Do you know someone who actually ran this hybrid and had good luck? Thanks, Jeff

I ran one for a while and it made great power at 14-15PSI. I'm sure a lot of other guys will chime in on this too. They're great if you don't want to run a larger cover, but they do give up efficiency for sure.

Thanks Cordes, that eases my mind. Jeff

Thanks Cordes, that eases my mind. Jeff

For a street car that isn't trying to do a ton of custom work or wring out every last drop I think they're pretty good. Anybody that rode in my GLHT back when still talks about the car when it was set up that way. It was amazing from stoplight to stoplight.

My CSX with a TII turbo machined for T04E50 trim/stage II turbine wheel got 99.7mph at the end of a 1/4 mile with only 12psi.

Wow, that's really scooting along for 12PSI. Nice work.

That REALLY eases my mind. Thanks guys.

I dynoed my old shadow with one of these "half assed hybrids" on a 2.5. Made 210hp/265 torque at 15psi. Just an intercooler and 3in exhaust other than the turbo.

Im hoping for better than that but reliable would be good at this point. 265 pounds/feet in a 2650 lb. car is pretty healthy IMO. jeff
