2004 mustang gt supercharger?

Question

ok so i am buying a supercharger for my mustang gt. I like the idea of the roush sueprcharger kit but it is 8 grand. Is it worth it over like a vortec one? What kind of horse power does it give?

And then i assume that the supercharger is better then a turbo charger right? Or am i looking at the wrong thing? HELP!!!!

it is ashame when idiots like that reply. First of all i did not say i was going to go street race, second of all anyone who would suggest a nitrous system over a supercharger to a "inexperienced driver" is a idiot. If you don't have anything positive or helpful to say don't respond to the question...

Answer 1

Don't listen to the people spouting about nitrous oxide, NO2 is a very good way to turn pistons into ashtrays. Roush kits are engineered well enough that they will honor the factory 36,000 mile warranty with them installed. We have had several Mustangs and F150s in or shop with Roush kits and I have never met an unhappy customer with one. You should be able to gain 100 HP fairly easy if you listen to Roush tech support.

Answer 4

A turbocharger will always produce more power with the same amount of boost than a supercharger. Their downfall is that they are a lot harder to install and set-up. A supercharger is a good modification for the average backyard mechanic because they come with everything you need to properly install them and set them up. I would go with a Vortec or a Kenne Belle. The Roush is not any better, and costs more. The Kenne Bell twin screw is one of the most efficient superchargers on the market. Nitrous is great, if you enjoy rebuiling your engine every year. I would only go with nitrous on an engine built for nitrous. If you are going to spend 8000 on a Roush, you might as well go to a good performance shop and have them install a turbocharger and set it up for a little more money, it will be well worth it.

Answer 5

The Roush supercharger is going to give you a broad power curve. You will get more power at lower RPM's than Vortech.
And you will have more horsepower under the curve. With a Vortech you will have more peak power and it will take a little longer to get there. If you like the idea of the Roush supercharger than look into Kenne-Bell and Whipple. They will be less expensive than the Roush and at least the same if not more efficient than the Roush. If the Vortech interest you, I would look into Procharger. They are self contained and you do not have to tap the oil pan. The power for either is going to depend on how much boost you run, which can be changed by swapping a pulley. In my personal opinion, if your car is daily driven then I would go with a twin-screw like a Roush or the others I mentioned above. The power is always there and you dont have to wait for boost. If you take your car to the track a lot then I would go with a centrifugal supercharger like a Vortech or a Procharger. They dont produce as much heat as a twin-screw.

Answer 6

I will give you some real help! I love fast Mustangs! I would buy an ATI Procharger. The are reasonably priced (if you call $4000 reasonable) and you don't have to punch a hole in the oil pan like on a Vortec because the oil is self contained. The problem with turbos is that a good kit will cost $6000 to $7000 because there are not many manufactures. Nitrous is a temporary solution to an all day problem, not enough horsepower! With 5 to 10 psi you should get around 100 to 150 horsepower on top of the 300 you already have.

Answer 7

Kind311, roush is a roots supercharger, not a twin screw supercharger. Even though roots and twin screw superchargers are simular they are not the same. Nitrous is not a replacement for supercharger or turbochargers and yes the coment made by the first person was very stupid. I dont think Dennis has raced anything in his entire life. You will get about between 90-120hp out of a roush depending on the tune, pulley size, and octane of fuel you use. In my opinion it is not worth the money. The first choice you have to make is whether to get a turbo charger or supercharger. A supecharger is the best choice if you are looking for something that will give you good hp and tq. As far as looking for the most hp possible, a supercharger in the long run will not give you as much hp as a turbo charger but as long as you are not looking to get into competition racing, you will never need the amounts of hp where it will make a difference between the two. Also with a supercharger you get your hp as soon as you hit the gas, but with a turbo there is turbo lag so the turbo doesnt kick in untill you get your rpms up. Superchargers will be less expensive then turbochargers. I would go with a supecharger if I were you. Your next decision needs to be what type of supercharger do I want. There are 3 different types of superchargers. Roots (roush, eaton),. Twin screw (kenne bell, whipple), or centrifugal (vortech, procharger). I will put a site you can go to in my sources so you can look at a in depth difference between the three but ill give you a quick run down here. The roots supercharger gives you good hp and good tq. It gives you very good low end and mid range power. The power levels for the roots stay very consistant from low end to high end. The centrifugal works very much like a turbo, it gives you very good hp, good tq. The down side is the low end power. There is very little to no low end rpm power. The high end power is very good though. The twins screw gives you the best low to mid range power. The downside tends to be the high end power. In my personal opinion with your 04 gt mustang, I would go with the twin screw if I were you. Unless you plan on driving around all the time at 100+mph, you want all your power to be available in the low to mid ranges. In my opinion the two best twin screw superchargers are kenne bell and whipple. You can get either one installed in your vehcial with all the necassary components for about $5,000. You will get awsome hp and tq improvements with either of these superchargers. (probally between 110-150hp and tq if not more depending on your set up) My personal preference between the two is the kenne bell. If you are looking to save money, your next choice should be to go with a roots supercharger. You can get a used eaton for a great price. I dont want to give you a quote because I havent researched it but it would probally be at least half or even a quarter of what a kenne bell or whipple would cost you. Keep in mind that you dont want to go over 450-500rwhp (550-600hp) unless you build up your engine. The people that do your supercharger install can explain this to you unless you do it yourself then just post another question. Sorry this was so long but it kind of had to be. Good luck, you will have a blast with what ever you choose. Let me know what you go with.

Answer 8

Adding either one will cause an inexperienced driver like you to destroy the car in street racing. There is more to setting the car up than just bolting on the kit, A nitrous injection kit has about the same acceleration at a fraction of the price. And won't need oversize oil pan capacity, improved oil pump, larger radiator and a bunch of other details to make it work. If you want the turbo or supercharger sell your car and buy a factory built version.

Answer 9

Lets see, new supercharger $8k, Nitrous $500, or go for a used Eaton off a old Thunderbird SC 89-95 for the same price

Answer 10

all right here we go first i'm a chevy guy mainly fbodys (camaro and firebirds) so mustangs are the enemy. but there's a couple of thing you want to look at first whats base boost and how many upgrades are avaible i.e. pullies intercoolers (if you want to go turbo)
with roush your mainly getting the name but it may also take more abuse. not 100% sure on those. if i where you i would go to a COUPLE mustang forums and see what there're running and suggesting.
