585 rwhp Roe S/C, What lb

[mntngts99]

I have a 99 with Tubes/filters,H/F cats,Catback and some nos. I will be doing the Roe S/C as a fall project. What lb pulley is needed for a basically stock motor to achieve nearly 600 rwhp. My plan is to also use a 75 shot of Nos to help keep temp's down.
Thanks

with the mods you have I would say a 7 lbs should do it.

then again a 7 may put you over a bit.

But why stop at 600? lol

NHRA for now is what's stopping me. Local track said NO more 10's tell I meet all safety upgrades. I figured that on all boost I should be low 11's without the 808 rwtq that I make on the Nitrous. The extra shot will be for fun when not running at that track.

Yes, on a basically stock motor a 7# should do it. I'm at 598 with a 5# and headers, exhaust, 1.7 RR, and EMS air box.

Thanks! We've got a great tuner here. He's a Viper owner and really knows what he's doing. It's Joe Donovan (PBJ) on the board.

I think they 7# pulley is the way to go with a basically stock forged psiton motor. If I did not have cast pistons I would be running the 7# pulley. One 1997 car in our group went 10.36 on a 7# pulley and sticky kumho tires. You may still need more safety equipment even with the 5# pulley.

Thank you
fuleman a 5# pulley at 4700 to 5600 ft elevation should only get me in the mid 11's, Am I wrong on this?

I would suppose so, what kind of tires are you going to run?
