Roush So where are the bottlenecks on my 2004 SC saleen?

[THX 138]

the throttle body looked like a stock one bored out or something no? How many mm is it now? What are some other easy upgrades?

I have a family machine shop. Although I don't know how to do everything myself I've learned everything I've wanted to so far. We have 3 CNC mills, two with 3 axis and one with 4. They're kind of old fashoned so they're not up to doing complex surfaces unless I lean how to do them with loops like the old days when they were made.

Go with the 75mm tb factory is i think 65mm My s4 blower car gained a solid 10hp to the wheels after a retune with tb. Let me know if you want the list of the best mods and simple mods to make that think wake up and with tires run in the 11's like mine. [email protected]

I have an 04 S/C and I've done the following to mine:

Accufab 75mm throttle body,Bassani ceramic coated headers, Bassani o/r x pipe,Tunable Induction cold air kit,Chicane pullley,SVT focus fuel pump,SCT tuner,MGW short throw shifter, and 3.73 gears. These are probably the most popular upgrades on our year Saleen. Big difference in power too!

I don't have headers? Do they use the stock GT exaust manifolds? Do I have 6 cats?

 

[justin]

Nope no headers. They are stock gt manifolds. I had 4 cats on my 04 and 6 on my 03. So you should have 4 cats on yours.

port your lower intake...those ports suck. Weld tabs of your intercooler gaps, do a full exhaust, cai, and tb and have fun!

what what? Are there pics of this procedure? How much of an improvement was the Cobra IRS?

 

[Saleen87-65]

cobra irs is just not worth the hassle from my experience. sure its a little bit smoother, but it was a pain for me to deal with. Get some MM LCA's and a panhard bar have at it.

No pics of anything that i know of, if you pull the blower off and yank out the intercooler, you'll see the huge gaps tha tneed to be covered with some metal tabs. The lower intake isnt that big of a deal, but when my supercharger got yanked, we noticed how tiny the ports were. Expected them to be bigger

Start with fuel pump mass air injectors, tb, 10inch open air filter, gears and a tune. OH a pulley too. Chicane intercooler is a good deal too. Like i said get a good sct tune, and enjoy the car, no other car like it thats for sure.
