    Smile how much more?

    i had the 3.70 pully on


    and i just put on the 3.4



    how much more boost will i gain from this and how safe will it be, before when i had the 3.70 i was making about 8 lbs from what i could read on the gage

    i havnt driven it yet to find out what the increase would be

    also how much can i spray it with out bowing it up?? right now i have a 75 shot on it but i want to step it up to 100

    thanks

    Kinda need some info on your setup.... stock motor... whats your hp goal? the blowing up on anything depends on how hard on it you are...

    im guessing 5.3? id say you are pushing your luck already. I blew my 4.8 with 10 psi and about 200 miles.... but im pretty hard on my stuff. 500 hp is getting close to the limits imo for reliability.
