How much boost can a 3.8 take?
Well, from our founding fathers, the 3.8 can take stock boost which is 7-8lbs! If you're running a pulley small enough to make more boost than that i think you guys should watch out!
Anyone running boost higher than that must have a professional tune, this is obvious cause stock cars can't do this. Boost means power, power means best 1/4 mile period. If you guys want to go fast, you must run the stock pulley, unless of course you have "MODZ" this will let you run smaller pulleys!! I hope i can help you guys make the 400whp mark you're looking for!! Lets talk power!!
