You are correct… It will not have the top end of say, a GT35R but it the fact that there is no low end penalty is simply genius. 380whp is the pump gas numbers at 23psi if memory serves.
From reading the private forums where Robert @ FP posts alot, until they can get a costs down in manufacturing, it will probably stay at $1500. According to him (and that’s the salesman talking), he is not making very much money if anything on these turbos. Take from that what you will. I would get my name on the list because it’s going to be a long time before the price will come down, IMO. If not, I would look at at GT3076 from ATPTurbo or something similar in size if you are looking for that kind of power.
