ok guys, im having trouble, im not too performance savvy, other than basic bolt ons, like the ones i got, i wanna ask you guys for help to make my stang a killer, doesnt matter what, apart from n2o, or sc, or turbos, anything else, like ive heard stuff about stroking the engine to make more power, but idk, help plz!!

 

my rec is if you really want power to just save up and supercharge it.

you already got the 4:10s which make a good difference.

i dont think you can stroke the 281's though

 

but dont you have to go through alot to supercharge it though?, like forged pistons and rods, crankshafts and stuff like that?

 

it all depends on the tune, dont expect 700hp, but with a good tune you can run around 400 pretty reliably, some people push it up to 450 and dont have problems, then again, some blow thier engines on a lot less, it all depends on the tune.

you need a plan man, forget what is needed, find a target number for HP or TQ yer looking for and then see what is needed to hit those levels then modify yer plan if needed

once i get rid of my 04 GT, next year ill pick up a 5.0 My first goal is +300 at the wheels and i got a plan on that, the next stage will be over 400HP which i can get after i supercharge her


So, what do you want with yer car, a mean street machine? do you want an all out dragster? is she a daily driver or a fair weather warrior? is gas economy a concern?

or are you just looking to whoop up on some imports?

 

well im not looking for an all out dragster, but a vicious street machine, whoop imports, camaros...corvettes if possible!!! i know i aim for high horsepower, 500s maybe, just dont know how to get there
she is my daily driver too.

 

500's yer gonna whoop up on corvettes not ricers. lol.

High horsepower 500's is gonna require an engine build, that gets very pricey. First off, you need the equipment to achieve those levels, ie, big boost. That will cost ya pretty good right there, im estimating here but im figuring at least 6-7 grand.... yer gonna need either a twin turbo setup or a supercharger, and not something crappy either yer gonna want high quality so you dont destroy anything.

. Then to be able to hang 500's reliable you will need to drop 4-5 grand on getting the engine built. And im pretty sure you will need a rear end overhaul

that gets a bit far out from my experience, im sure some people here can chime in.

think of this, Cobra Terminators are rated at 390hp, and they destroy most imports.

A good goal may be in the 350-375 range on whp, yer gonna have plenty of torque, and you wont have to promise your first born to satan to afford it.

 

375, not bad, hopefully, 400, i guess money might not be an object, since most of the stuff to get me Enourmous horsepower ie 500 600, will probably be after UTI, how much hp r u hitting, with what?

 

You can stroke 281s. They have 3.75" stroker cranks that turns it into a 302 (w/ a slight overbore). Hell, they even have stroker kits for the 5.4, which is a little too much.

However, if it was me, I'd try to squeeze as much power as possible NA before I'd go FI. This way, you can make the most of FI since you'll have all the restrictions removed. Also, have you considered a 5.4?

 

ive thought about 5.4 engines, but then im face with the issue of "will it fit? will it work properly?" not to mention, with new engine, ill need a new transmission cuz my stock tranny probably wont take it.

 

where can i take my car to stroke the engine into a 302, and what do i need?

 

don't waste your money. you're going to need new internals: not only the crank, but rods too i believe, and you're hardly going to gain any power. Maybe 20hp. Keep your stock motor, get full exhaust, and then buy a Vortech kit and run it at 10psi. That should get you around 450hp, and just under 400rwhp. At that power level you'll need to upgrade your clutch/trans, and rearend if you plan on running a sticky tire. This should get you high 11's in the quarter mile, which should pretty much put you over 95% of the cars you'll run into on the street.

 

but if i want more boost, i have to upgrade internals, like crank and piston rods?

 

yes, so just get forged internals, supercharger cams, a supercharger, full exhaust, plenum/ throttle body, and a dyno tune. This should put you at 550 hp easy, on 10-12lbs of boost.

 

damn, how much r u hitting?? oh and by rearend, do you mean like diff, or a whole new rearend?

 

There's no replacement for displacement, no matter how little the gain. Plus, a .25" gain in stroke is pretty damn good, which will give more torque (something 4.6 lacks due to size). However, I'd wait to do this until you need a rebuild or to strengthen the engine since everything that moves needs to be replaced (crank, rods, and pistons). Eagle makes some good stuff for this. As for the 5.4, read the thread. The 5.4 fits w/o a hitch, except you may need to cut a notch in your hood or get an aftermarket one.

 

yes, diff. and axles. you should also get the axle tubes and torque boxes welded up when you get the rearend built.

 

my car isn't supercharged yet. right now i'm putting out 266/300 to the wheels, which is right about 306hp and 345tq at the motor. An 8psi supercharger would put me at around 425hp at the motor and 370rwhp.

Just a side note too....

Im willing to bet that for a DD a fi mustang with more than 400 rwhp (or there abouts) running the 4.10s will be a bit much and traction will be a major issue. LOL you would be smoking the tires at every blip of the throttle! Just something to remember... if ya ever get to your desired hp.

 

For a daily driven car 02silver is dead nuts on. I'd stop at or before 425-450 rwhp and save the big stuff for track days. Traction becomes a major issue on street tires when you start pumping out big hp. Not to mention, a 500hp car is almost a bitch to drive. You have to be judicious with your application of the throttle and it's blindingly easy to get into serious trouble before you know it... the tires and street can't stick 500 ponies. You need an improved surface and proper tires to plant that kind of power. Besides the fact that you have to maintain the car to the amount of power you make. 500hp cars require regular diligent maintenance or they don't live long which is exensive and a PITA in its own right.

I'd ask yourself first and foremost, how much you feel good about spending on gas a week, your average weekly mileage and then we'll be able to decide what power level you are limited to by your fuel budget. HP is directly related to how much gas you can burn efficiently... the downside should be apparent.

 

well since i work for my car, i got no payments, gas isnt really a problem, as for traction, a pair of tires like the nitto nt555 would help wouldnt they? if not maybe the nt555 drag radials, i heard theyre pretty good on the street, what do u guys think?

 

uh... maybe you shouldn't be working for your car. don't dump all your money into it at once. be sure to save some cause the car can be taken away from you in an instant and all your invested money will be wasted. The nitto drag radials won't even come close to hooking up a 500hp car. They have a hard time hooking up a full bolt on GT with 4.10's. Even Mickey Thompson ET street radials won't hook up on the street. You have to get them nice and hot on a sticky surface to really hook. My buddies SS Camaro puts out 375 rwhp with the stock 3.23 gear, and he spins 1st and 2nd on the street. At the track once heated up, he cuts 1.6x 60fts. The Mickey Thompson ET streets will hook better than Nitto's or BFG's on the street, but they still will not dead hook under normal driving conditions. So if you want the best dry street traction, and no wet/rain weather traction then the M/T ET streets are your tire. Then you have to consider how much you drive your car because they will only last you about 5,000 miles, and they usually go for around $200 a tire depending on what size you go with. Your driving habits will also have to be altered with that kind of power. You're not going to be able to floor it all the time because you'll either get sideways really easy, or be 1 block further in a few seconds. I know that when I drove my buddy's Camaro, I went from 35 mph to 70 mph in about 2-3 seconds.

 

I'm goin with blownstang on that... my car makes 280/333 on it's current tune and I have a tq arm which dramatically increases rear traction and 285/18 tires and it still spins hard through 1st and 2nd at any provocation and even spins 3rd on power shifts with 3.55 gears. 500hp cars on the street are too much trouble. Everyone wants one till they've had a chance to have to rely on it, then they sell it and get a focus.

 

500hp is for drag cars all the way. For track or street cars you don't want massive power unless you can stop it. Suspension is the way to go if you eventually want power. a car with 280 at the wheel that can put it all on the ground will smoke a car that has 320 and can't get traction.

 

hey thanks alot for the advice guys, thought, since, like i said, most of the big stuff wont come until after i get out from college, im already saving for a separate stang, already got a 04 cobra lined up for me, but i wanna keep that stock, maybe a few bolt ons, but my gt, ill probably save it as a "sunday car" lol, but yeah just trying to get some tips on how to hit big horsepower.

i was wondering though... if i have to get the forged internals for a big boost supercharger, why not just stroke into a 5.0? just a thought

 

I'd mod the Cobra and keep it as my "sunday" car. keep the GT stock and use as your DD.

 

well i was thinking, this way, i can have a car, a DD, that has plenty of *****, then, noone would expect, that my sort of gt stock looking stang, would whip most cars at the track, idk, just my form of twisted irony i guess, haha

 

I agree with the others here. Stick in the 400-425 range and you should be good. Buddy of mine has a 93 Cobra with 633rwhp and a 04 Termi with 550rwhp. He is able to get both of them to hook up pretty good on the street, but it is a delicate pedal dance to make it happen. The 93 is on MT ET Streets and the 04 is on BFG DRs.
