I was just curious as to what was the most power someone has made off of a non-intercooled YSi setup. Doesn't matter what motor it was on.
Thanks a lot!

Lordy, is anyone there?
Well, the NMRA REN crowd is up over 1000 easy on Ribbed pulleys and 25+ PSI

I know renegade is making a lot, but where over 1000hp? I heard they are making more like 30-35psi off the YSi's too.Originally Posted by saleen_n_around
I'm looking to break the 1200 barrier in a few weeks.
Have you break the "barrier"?Originally Posted by Greg D
Well anymore than 1200-1300 hp you will probably want to step up to a larger blower anyway as the YSI is rated at 1200hp. This is damn immpressive out of a non- intercooled blower in my book.

Haven't been to the dyno with the blower yet. Still waiting for a pulley to be made by RCD. The motor made 773 HP at 6400 RPM with out the blower, so 1200 is certainly reachable. I'll post the dyno sheet when done.

Depending on the induction and any other restrictions I would guess about 650-700 with 14 psi and about 900 with 28-30 psi givin the proper induction of coarse.

I guess if you were using something like methanol for fuel, the lack of intercooler wouldnt be a big deal.
For what its worth, I made 735rwhp on a Dynapack with pretty conservative timing, as the dyno went nuts if I increased it, on regular SUL fuel 97RON with my LS1. equiv to US 93 PON octane. ( I do have an IC though )
Squirting a little methanol on top of that, has improved things greatly, although I havent been on a dyno yet, but I am trapping 143-145mph.
So I'd guess its safe to say I have 800+rwhp now.
Hopefully that will improve with my new intake.
In theory I'm spinning the blower to around 68000rpm at 7000rpm crank, although things are dying a little after 6000rpm.
I'd say it is slipping a little though up there.
it will make 16psi at 6000rpm and almost 20psi at 7000rpm, 382 LS1.
Could make more power with a higher CR and/or race fuel, but I opted for 8.7:1 so I could use pump fuel safely.
I know of one car that only made 760 to the tires ;) with a big blockOriginally Posted by YellowNotch
(got to love that when people say that).
To tell you the truth you are the most I ever heard of. Vortech power baby!
Little late in posting this, but my little YSI made 1182 HP, but more impressively, it made 1142 foot pounds of torque!
