Hey guys, lets just say I've been
Ive seen some impressive times from the maggie trucks here, it gets me warm and fuzzy.
I know this thing is gonna have too much power for the rear wheels, I am about to fire it up for the first time, knock on wood, and the "go drive it" bug is biting.
I'm thinking 475 rwhp, from this set up, whats your professional guesses?
majority of stats in sig except stock 3.4 pulley and 255/40-17, 26" rear tire.

How much does it weigh?
3.4" pulley is probably only gonna be around 4-5psi with the cam/headers. I think 425rwhp is an ok guess too. Prolly gonna move out nicely once you stop spinning.

Car weighs 3700. I was guessing about 4 lbs of boost, as i am at 4600' ASL
The springs are temporary, they will be close. I am going to do a "stage 2" upgrade after it gets running and the bugs get worked out. I will be pining the crank, 2.9" pulley, 100mm idlers, 60's, double springs, Bosch 044 fuel pump, 92mm tb and maybe the upgraded idler (can't use with 100mm idlers I heard?) My ultimate goal is 500 rwhp on this setup. I am moving back to Michigan next spring, go that will put me at an advantage at 650' ASL

The 3.4 pulley is good for 6lbs on a stock 5.3L. Those tiny tires and the big stall are going to light 'em up. Are LS6 springs good for .578" lift?
