Will 2 extra psi hurt?

[Motorhead350]

I know we talked about this before, but I now know for sure if I changed my pully to a 360/3.6 it will bring me up by 2 psi. I talked to Procharger about this and they were not sure about what our stock engines can handle. So it looked like with this pully I would be pushing 11psi and probably around 440 RWHP.

Does this sound ok?

I know it's a risk, but what do you think??? Now that we know a little more...

All thoughts appreciated.

Thanks.

BTW my blower should be back this coming week!!! :burnout:

I haven't had any problems yet and I go WOT on a daily basis. About 12 psi with a D1SC on a stock engine, tuned to 425 rwhp. Bob Kurgan was comfortable with these numbers.

Mine made 445rwhp at 8psi with a slipping belt (since replaced, so figure up to 10 psi now) and at around 29k miles on the stock engine, no problems. I run it hard 98% of the time. Just make sure it can supply enough fuel to keep it from running lean at WOT. I am running twin GT pumps from DR.

Mines been fine at 11+/-

I ran w/ 500 RWHP on a Street Tune w/ ~10.8 PSI.

YMMV.

Im pushin 12.5psi wot, with 430rwhp, BUT I'm injection methanol as well. I plan on going to 14.5 psi with my meth system???? My goal is 510rwhp.... on a stock lower end... I'm going for bust!@!!

Glad to hear all of this. I guess it's in the tune.

Blazin71, I went to Bob and I'm going back to him.

Steve, I need a race gas tune and I'll be all set!

This should be interesting.

I have been running a 3.6 pulley from the get go...

She's currently at 444/401 pushing 11+ psi...

You'll probably need a BAP to keep the FP up...

Your tune can set you free....

Dom, when I went with a 360 pulley (when I had the stock engine) I had to add a Diablosport MafiaMAF and move up to 60 lb injectors (twin Cobra fuel pumps) in order to keep the engine in a safe tune. The big thing is HAVING THE MOTOR PROPERLY TUNED. Never had a problem at all. Boost was around12-13 lbs. Once that was done I was runninig consistant 12-3/12-4 et's. Car pushed 475 RWHP on the dyno with 93 octane.
