Before I allow myself to get wood. What are the numbers, and how did the torque curve look?

I believe it is just now getting tuned out. No final numbers yet.

It is my car. I was told today that it was 450 RWHP and 380 lb of torque. Apparently, it takes 6-8 months to make a custom belt and so it will be hard to go to a smaller pulley. Sam is going to try to use smaller pulleys before I pick the car up on Saturday, but no guarantees. I had hoped for 650 BHP.

Too late!!!

How much boost was your car running on for 450/380?

Yeah, and that is without the Motordyne Test Pipes, Stillen Exhaust, and Aqua-mist meth kit. I could have had my car back months ago, for less $ and more power. That is at 9-11lbs of boost. He is going to try to wrangle smaller pulleys on there, but without a full selection of belt sizes it will be really tough. I am sure the system has a lot of potential but that won't be for 8 months.

you dont sound happy about that lol im sure sam and the guys will get it pumping out more power soon. i mean its what they do and what they do well from what i've heard.

Sorry to hear that Spawn, judging from some of the posts they made about it being more of a cool factor I was worried the power wouldn't be that great. For the meantime you'll be the only twin supercharged system out there, and hopefully GTM can get the numbers better or you'll be the only twin supercharged system out there.

Good luck to both parties involved, this is a step in the right direction and someone has to lead the way in this new design. It's not always pretty at first but I'm sure they'll do their best to make it right!

I just got off the phone with Sam and got some clarity. It is at 480hp now and about 360tq. However, that is on 91gas. He thinks he has a way to get the smaller pulleys and on Meth it should be over 700bhp. I'd be totally happy with that. I will post more as I know more.

that must be one hell of a pulley to jump that much HP

Even though you very clearly stated "700 BHP", it's probably safer to talk in WHP numbers around these parts to avoid any confusion.

Sorry about that. I am focused on BHP since my brother got the new GT500 and has 650bhp (supposedly). I will speak in whp from here on out.

No worries. Your brother's car is a cool one. Very fast in a straight line. I would not expect to compete well with that in a straight-line given its huge torque numbers. Anyway, raw numbers don't matter much. If you can get yours down/around the track faster, you win!
