To supercharge or not?

[matty]

I have a 2006 mustang GT, I am now exploring the option of increasing the HP of my vehicle, currently I have a Saleen shifter, a couple Saleen aesthetic parts and an AFE Stage II Air intake). I’m thinking supercharging my mustang might be a viable plan, but I’d be open to any other suggestions you have.

I have been comparing the Saleen supercharger with others and I think I have narrowed it down to the Saleen and the Roush, I'm wondering from your point of view why the Roush would be a better choice than the Saleen or vice versa or if you have any other suggestions in terms of blower manufacturers.


Ideally if I could push it to close to 400hp (is it possible to get 400 hp at the rear wheels, or should my first goal be 400hp at the fly wheel and then try to move up) while keeping it naturally aspirated that would be a great alternative to the supercharger I think), do you have any other suggestions (I have the air intake kit already and will get a tuner after I add a few other parts). I’ve heard that headers tend to not produce a huge power gain in the GT’s as the ford did a relatively good job making sure that they aren’t too restrictive from the factory, what are you thoughts? What other parts would you suggest? If possible I’d like things that won’t likely cause too much grief in the unlikely even of a warranty issue since this car will mainly be a daily driver with a little bit of racing, and will be the first car that I really start to tune (although I do understand the nature of aftermarket parts, which is one reason I liked the Roush warranty and the Manguson powertrain warranty add-on which assumes ford’s powertrain warranty).



Thanks for your help,

As far as how they look under the hood the Saleen is unbeatable. Sleek, low profile and sexy as hell.

TO supercharge or not to supercharge

Matty;
I guess there are a couple of ways to go. One being nitrous the other to use the other power adder.
I chose supercharging for seceral reasons.
1. You never run out of it like you could with nitrous. You step on the pedal, it's always there like an old friend. Come to think of it, you may start to look at it that way if you've got it as bad as I do.
2. You can still stay EPA friendly.
3. It's really a simple mod.
4. You don't necessarily need to do a bunch of internal mods. if you don't go nuts with the boost.
Saleen v/s roushcharger? I've got a 06 roush stage 2 and I chose the saleen unit.
Why? Which is better?
Technologically the saleen unit is quite a bit more modern. It's a twin screw impeller v/s a roots style for the roush. It will flow a lot of air through your engine without superheating thi incoming air/fuel charge like the roush.
Also the saleen unit is a very simple well engineered design that is easier to install.
I live in the central valley of CA and it gets hot here in the summer. with 12 lbs boost my inlet chargr still stays around 125 deg.
If you decide to go with the saleen call jim jr. @ team jdm.com in NJ.
I've bought most of my stuff from them and they are very helpful with install questions and follow up questions. Saleen will also do an install for you even though you don't have an s-281. Any more questions let me know.

The Saleen S/C is the only way to go in my opinion.
If you only want 400rwhp the JDM stage 1 with the 3.6" pulley will do that and then some.
My Stage II with the 10 psi 3.4" pulley is awesome and along with my headers is putting out an estimated 475-490 rwhp.
My car has not been on the dyno yet but my 1/4 mile times of 11.427 @ 119.92 with a weight of 3680 lbs gives that as a rwhp.
If you think that's extreme on stock internals there are others running 12 psi on these without one engine failure on 500+ kits sold.
At 10 psi or more it is suggested you upgrade the fuel system with better fuel pumps. do a search on the GT500 fuel system.there are a few sources for it. One of them is JDM which has a current special at $699.00. I paid $900 for mine a few months ago.

Do not spend the money on the Saleen 475hp kit which runs around 375-380 rwhp with disappointing results especially on an auto.

Wow, I didn't know that JDM was able to get that high, thats trully impressive especially for the price, and it is a pretty sexy looking mod. Do you know if it will fit under a stock GT hood? Now I still have a couple questions, if I was worried about some of the possible warranty issues do you think I would have more of a headache with the JDM product, especially that I'm in Canada. Does anyone know of any manufacturers (other than Magnuson and roush) that offer a powertrain warranty? Saleen doesn't if I'm not mistaken, correct?

Also if I did want to stay naturally aspirated for now what would you suggest? Would I have to dump most of these parts if I were to add the S/C?


Thanks again

I have to tell you that with these mods you can forget warranty. If you have a dealer install it and you stay at stock 4 psi you will have a car with a warranty which will run around 12.5 seconds. A far cry from my 11.5 seconds. I ran my car hard for a year and a half before installing the S/C knowing full well that my warranty is gone but another 400+ people are running the same setup without a single failure.

If you want to stay N/A you can purchase the SCT X-Cal II, the C&L Racer inlet tube, the JDM Cold Air Kit, and a set of longtube headers. All of these mods can be used later if you want to install the Saleen S/C with the JDM mods.
