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.Quote:

Have you break the "barrier"?Quote:

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.

I hops i can get 1000hp,The engine makes 398hp natruls and i spinn the ysi 67000 and a water I/c
Do you guys think it possibel?
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 blockQuote:

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!
