Hey guys hopefully I can come into this section sooner hopefully than later because I have my order to ATI through THR in. (Thanks Mitch and Brian!) I was wondering if theres some things that I should know after I bolt up the blower. This will be my first forced induction car I have ever owned and I would like theexperience to not include blowing up mymotor. Also,I was wondering what kind of boost HP wise to expect from running the Stage II kit with the smaller pulleys and 3 core FMIC as long I keep the tune fairly safe. I took down my laundry list of mods, so here they are again so you can get a better idea of what it's going on. 1/4 mi. estimates would also be welcome.

Stock 4.6 2v shortblock
Ported 2v heads
214* intake/exhaust @ .550 lift cam
75mm intake/plenum
stock pi lower intake
MAC LT's
BBK o/r h-pipe
Flow 40 catback

 

welcome to the club, you'll love it

you should easily be able to make over 400 rwhp with all those mods and the appropriate pully, just depends on how conservative the tune is.

good luck!

 

Power mostly depends on what pulley you will be running, and the 1/4 mile depends mostly on your susp, gears, tires, and how well you can drive.

 

on a scale of very conservative to so aggressive maybe i'd get one pass out of the stock shortblock what are the ranges of HP I could expect from my setup. just kind of wondering what kind of difference a tune would make.

 

The time listed in my sig was run on lowering springs and Bilstein shocks/struts wearing heavily worn Nitto 555R DR's with same engine mods as what is going to be supporting the blower. Now I have fresh BFG G-forces and subframes and upper/lower control arms done also. So is the tune the one largest factor that will affect the outcome of what I'll be putting down on a dyno?

 

I'd be cautious over the 400rwhp mark on a stock shortblock, but yes tune is extremely crutial for pulling the largest amount of safe, reliable power.

Congrats, btw. [8D]

 

Yes, the tune is most definitely the biggest factor in what your outcome will be. If your tune is not dialed in for your setup, you won't yield optimal results and can ruin your motor very easily. As far as dyno numbers go, its impossible to even estimate what you will be running without knowing what size pulley you will have. Given the right tune, you could be anywhere from 330rwhp to 450+. It all depends on how much pressure your running.
