Hooking up will not be such a problem at the track, not bogging with slicks or snapping my rearend will be one hell of a trick

Exactly what I was thinking, slicks and 400hp is gonna put a little strain on the rear.

I currently drive a 2002 mustang gt 5 spd with 4.10s, o/r x pipe,excal 2 tuner,and mac catback. Those are just the power mods done to the car.
I recently purchased a P1-SC Stage 2 supercharger kit. (3 core intercooler)
I would like to run 8 pounds of boost and produce at least 375rwhp.
Is this asking way too much even when profesionaly dyno tuned?
Or should I just run 10 pounds?
Without LTs, t/b and plenum its probably not going to see 370+ with only 8 Lbs. you might see 370ish on 10 PSI.

with 4:10's you'll run through gears too fast. A freind of mine had 4:10's in his mustang and he was pushing 350rwhp and he had no traction and he just ran out of gear to quickley.
Your friend needs better tires and suspension, its not the 4.10s that were kiling him. Even with 3.73s, without the suspension done I was smoking off the nittos at 420 WHP.

What Im asking is will 400 be possible at 8 pounds without running too lean?
What are other people making who are blown?
You can safely make around 420-430 WHP, 450 is the absolute limit but at that point its pretty much a question of WHEN not IF.

Its good to know that im not the only one on here crazy enough to run 4.10s with a blower.
Also I will be using the 3 core intercooler and not the older 2 core
Everyone else can have fun sitting in the twelves while I hit 11s my first
Thinking like this is only going to do one thing.. disapoint you. It simply takes alot of seat time at the strip (not on the street) to get it to go 11s with less than 400 WHP. Even with 420/410 (10 PSI, full boltons with LTs, badass tune) and nittos + suspension work I still only went 12.40s the first time out, and that was with decent traction (for nittos). Expect mid/high 12s the first time out, until you start to figure out whats going on. This is assuming you have shocks/struts/springs setup for drag racing (or adjustable shocks/struts) and control arms/subframe connectors. If your on the stock suspnesion, you can forget ever hitting an 11, even with a slick.

So far as using a slick, you won't be able to really get the full use out of it. I was leaving at 4,000 RPM (on stock axle FTW!) last time at the track with the MT ET Streets, and I didn't see any tire spin. If you try to go out there on a stock 8.8 and pull a 5500 RPM clutch drop on slicks its going to break, if it hooks up at all on the stock suspnesion.

I have the 8 psi w/ 2-core and am making 361rwhp. I do have a Full upper and lower intake from Trick flow, but I stillam runningcats and stock manifolds. I also have a pretty conservative tune. So no, 375rwhp isn't out of the question but you will need at least a throttle body/plenum upgrade and free flowing exhaust.

By the way, I have 4.10s and they're fun as hell!!!

Mine made 395 at the wheels at 10psi with a 3 core full exhaust and a throttle body...

I've got 4.10s ... on street tires 1st gear starts and ends pretty quickly but its no big deal really... just shift faster.. makes for a cool ride when the tires start breaking loose in 3rd when it builds boost

He Needs REAL tires...DR,et streets or at least Nittos...No mater what ,with 4.10's traction is always an issue of sort....I on the other hand have NO problemn flyin through the gears....

im runnin sq v2 on stock pully making about 350 rwhp and i have 4.10's and love it first gear is very short and very little traction if you dont drive it right but if done right very doable. as long as your tune is good and your fuel system is good enough to handle the power there should be no reason why 400 in not doable. but that is the limit on a stock block/internals.
