i got this idea for a mustang 5.0 it goes like this. no appearance mods (stock look) but do heads, a cam, full exhaust (LT's off road H or X then some random loud muffler) then to top it all off a supercharger running about 5-6 psi. about how much hp/torque would i be lookin at and how quick in the 1/4? id do somethin like a custom tune too. 5 speed of course. just need to know cuz theres this black ws6 thats askin for it? ;)

What kind of heads, cam, etc,etc....
What do u think your compression ratio will be? with 6 psi I prolly wouldn't do anything higher than 9:1.
But if you ask me, its more fun to go fast N/A than with any power adders. Well, it's more impressive anyways and there is less of a chance of blowin anythin up. Just make sure you are aware of your compression and you should be fine.

we are going to need alot more info here really, what kind of heads? what price range? something like AFR's or TFS?

I would say stock shortblock, Entry level supercharger @ 6-8PSI (vortech S-trim, P1SC, etc.) Decent out of the box alum. heads, and full exhaust you will be eyeballing the 400 hp range with some tuning. You will need some chassis and suspension work to get it down to the ground though. Dont forget the intake. thats the biggest bottleneck on the car after the E7TE exhaust ports. The cam isnt that much of a necesity. The stock cam will work fine for quite a bit of power, and the drivability is unmatched. You are also going to be putting a major stress on the junk T-5 tranny

im not sure on the specifics yet cuz i havent gotten the car or anything yet. still just an idea. i know better tires would help but how else would i go about putting that kind of power to the ground? (im kind of a beginner) also, what kind of stuff would i need to do to the tranny. how bout if we toss the supercharger idea but raise the compression to somethin like 10.5:1 would that be a nice set up? i know its kind of a personal preference things so i should be making these decisions but like i said im new to this and im here to soak up as much info as possible and get some great ideas

Well to get that sort of power to the ground efficiently you would probably need to look into some lower control arms for starters, Uppers if you can afford them also. Gears would help since most of those things came with airplane 2.73's. With as many miles as most of them have, a traction-loc rebuild might be in order to keep you from one wheel peeling. Last but not least would be some nice weld in subframes, as fox bodies are notorious flexi-flyers. These are all things that would HELP tremendously in your quest, but not really needed all at once.

As far as the tranny... I would probably leave it alone and wait for it to break, because it will under hard launches and shifts and 400 HP. Some people have had them survive to 10's granny shifting them and catering to the weak tranny. With that much HP id invest in a new tremec TR500 or better yet TR600 when that thing gives up the ghost.

Raising the compression to 10.7 or so would require some domed pistons or really shaved heads. You can hit about 10:1 pretty easily with some aftermarket flat top pistons. Id say 10:1 shortblock, aftermarket heads, cam, and intake and you could net 350 at the tires with little work.

Now Ill tell you the shortcut.

1. Drag radials
2. Gears
3. intake
4. control arms
5. exhaust
6. 150 shot of nitrous

or you could just get the nitrous to begin with. I have seen bone stock 5.0's run into the high 12's with a bolt on aftermarket nitrous kit.

like you say, personal prefrence though, some people dont like messing with the juice.

0k so0 if i follow helmsdini's 6 steps about where would i be?? would a mostly stock engine be able to take a 150 shot?
somewhere in the 12's once you learn how to drive it with the juice on. Traps would be around 110 or so. Stock forged 5.0 shortblocks can step away from 200 shots with little trouble. Really almost anything can as long as you dont detonate. Nitrous doesnt kill motors, detonation does. Id say your limiting factor would be how much nitrous you could force through the small ports on the heads before it backfired in the intake. I wouldnt feel safe going much over 200 myself, but as far as breaking an engine from overpowering it... you would probably have to be in the 500-600 HP range and it may snap a rod bolt if you wind it really hard, or split the block in half. a 150 shot would be ideal as far as not pushing the envelope too hard.

Are stock forged internal 5.0's real expensive?? I'm used to paying an arm and a leg for LS1 stuff...
They are cheaper than LS1 parts right now....A lot of that has to do with the huge aftermarket for the 5.0's....And the longevity of the engines being around....Give the LS1 a year or so and prices will almost bottom out....

Why am I talking Ford stuff? ;D

Yeah, the good TRW forged piston shortblocks are '87-92 Keen eyes will mention that 86, and rumored the '85 also had forged pistons, but they arent fly cut for valve reliefs. I have picked up an entire 88 engine oil pan to intake for 150$ before with 100K miles on it.. they usually last to about 200K+ and loos tollerences makes it just that much better for spray!!

I dont think 5-6 psi of boost is worth the cost of a supercharger. Spraying your motor looks like a good way to get a lot of power at a better cost.
My Mustang has a Novi 2000R/R blower and a Paxton intercooler on a stock mod motor making 10# of boost. If I was to do it again I would go turbo without a doubt for what they can do.
My Novi can make 29# of boost and all the power I could ever want if I would build the motor to hold it and then replace everything I would destroy in the process of putting the power to the ground.
