I'll give you a hint. It has the letters R, S, and X in it.
Don't know too much about it other than it is in on stock internals. It is a little confusing as to what psi that was on but I believe it was at 14psi. He says he runs 7psi on the street so I think it was bumped up to 14psi just for that dyno. I'm guessing he is going to beef up the internals before he runs it at 14psi on the street but that is just a guess.
Anyway, if you don't care, sorry for wasting your time. For those of you who are interested in what is going on in the non-WRX car scene, I hope it was informative. Personally, I was quite happy to see that at least someone is making progress on getting some serious power out of the RSX.
