Most HP on a GT40R
Anyone know what the most hp people are putting down with the GT40r. Tried searching but seems like nobody runs more then 20psi. Anyone break the 600 mark with one?

Yeah, I remember the discusion about his numbers and at what psi it was. But either way it was one hell of a pull.

Yeah, it was a hell of a pull, but I thought Rice summed it up best when he said this:
congrats 
but te numbers need some clarification and comment so people can understand what is going on 
.....So for a full bridge port running 27+psi droping to 23psi and making 600rwhp on a dynojet on C16 its nothing miraculous at all in summary, by comparison my friend makes 578rwhp on a dyno dynamics runing 21psi droping down to 18psi on a half bridge with pump fuel and water injection...... I'll go dig up the power graph so you can compare

According to the compressor map, it should still be efficient to about 30psi, at least if you have the right hotside and other aspects of your setup. But it doesn't always work out that way on rotaries.
But it is not a turbo to run 8's. You should definitely go for something bigger if that is your goal.

I think you misunderstood. The turbo im using is much much bigger ofcourse. and in the right car like a a 1900lb r100 with a gt40r making 650hp will go 8's easily.
