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
