Hey all,
We got the engine replaced in our 06 mustang. yay! Now we are talking about putting the saleen supercharger back on the car at a lower level stage. We had a kit on the supercharger that made it produce way too much boost for the engine, which blew it, of which I had no idea that the stage we had put on the car was one that would take it to the line. Its a long story of miscommunication and not being warned of the possible problems, was told it would be one in million if anything happened to the engine.

Now the engine is brand new and we are debating putting the s/c back on the engine. I talked to Saleen and they said they would warranty the s/c and the drive train (except for the transmission due to it being an automatic) at stage 2, 475 hp. They gave me a couple different places to have this done that they recommend.

I already have the supercharger. Right now its sitting in the garage on a shelf.

However the tune has to be from saleen, which everyone says isnt very good. If we change the tune, it will void the warranty. Anyone experience this tune?

Is there an amount of time we need to wait to "break" the new engine in before modifying it? Its stock right now.

I really do not want to replace this engine again anytime soon and everyone says that its 99.9% change nothing bad will happen. But Ive heard that before. So any advice.

 

I would drive a new engine 1500 miles below 4000 rpm before I went to get it tuned. It should run fine on the saleen program if your just breaking it in. I wouldnt give it boost until you get a dyno tune so you make sure that expensive engine doesnt get hurt....

 

I agree with you about the dyno tune, the place we are thinking of taking it will dyno tune it when they would put the s/charger on it.

 

Break in the new engine first. Drive it to a shop that knows what there doing, get them to install the s/c and throw it on a dyno and dynotune that bitch.

 

just my 2 cents..

sell the saleen superchargers, and buy a 62mm turbo.

you'll put far less stress on your engine than a s/c, and you'll never ever have heat issues.

s/c is constant stress on the crank, journals, and bearings because they are always spinning.

a turbo won't spool up until a certain rpm (depends on your setup) therefore your crank isn't getting nearly as much punishment, and neither are the journals or bearings = less wear and tear on your engine..meaning it will last longer, and you'll have performance for years and years with less issues than you would have had with the s/c.

good luck

 

Never have heat issues with a turbo? Not to rattle your cage but turbos get their power from exhaust thus creating heat. I know since Ive had a turbo car.

There are plus and minus for both setups. My case for getting a procharger was due to ease of installation and less heat compared to a turbo (Procharger comes with an intercooler plus has its own lube not engine oil). Anyone that puts any form of forced induction without putting it on some rollers (dyno) is crazy. If you were happy with your Saleen SC just make sure you get it to a reputable shop and put it on a dyno.

 

if you have an air to air intercooler, you shouldnt be having heat problems with a turbo.

ive seen lots of turbo stangs run way cooler than a supercharged one, and never had any overheating issues, or even running warm.

but everyone's preferences are different.

 

Go through Saleen to get it done... thats a nice warranty...

And since they do not offer the warranty on the tranny... Get your current one built.

 

do you know how poweradders work?

because the way i am reading your post... you're saying a supercharger is constantly putting stress on a motors, because the motor is "always" spinning. do you think that CENTRI, roots, and twin screw blowers constantly put a engine in boost? well they dont my vortech'd car is mostly at a 10-15 vacuum at cruising speeds. even when i pull from stoplights at 1/4 1.2 throttle i dont see boost only vacuum.

personnaly i would stick with that saleen blower and get the warranty with it. 475 horspower is fun and if it breaks they fix it no questions.

your tranny get a upgraded valve body and a cooler to help keep it alive. if i had done that to mine it would of had a longer life.
