I think my GT3076r setup makes the 450whp range effectively. That's what I am at whp-wise right now running about 22psi, though I haven't dyno'd this exact setup.

The GT3076r struggles to make over 450whp at my elevation at 24psi. I'm sure at 30+psi it will be there, but i haven't pushed it.

also maybe a inline fuel pump and a aray of other fuel components he may or may not have. so this isnt much of a option

400whp can be had on 740cc injectors, but I wouldn't push them to the 450whp mark. Anything over 400whp on E85 will require 1000cc.

Coheed I disagree with you on the 740cc injs not being pushed past 400 WHP. Made 470-510 WHP on a few cars down here with them.


Nick = 470 WHP
Yeneil = 500 WHP
Manny = 524 WHP ( 740cc 4 bar )
Robert = 455 WHP
Greg = 550 WHP ( 740cc 4 bar )


Lets look at it like this.

It is 100 % safe to make 250-260 WHP on 370cc injs. ( This is facts )

so

370cc x 2 = 740cc

It is 100% safe to make 500-520 WHP on 740cc injs. ( This is facts )

Extremely high flowing (perhaps highest hi-impedance injector avaiable) 80 lb/min (870cc) Injector, : atpturbo.com

Dre I think he is talking about E85. Regardless I have seen 740's used to make 450 whp on the corn. 500 could be made if the tune is on. Most people like Coheed mentioned usually go to 1000cc injectors.
