Rousch And Saleen Use Stock Gt Block?

[Gearhead91]

Does anyone know if Saleen and Rousch use stock Ford longblocks when supercharged? ...or do they modify or rebuild the engines to hold more power? If these companies use the stock longblocks, I will feel more comfortable supercharging too.

I have an '02 GT, and I need a blower. I am trying to figure out if the stock motor can take 6 - 9 lbs. of boost safely. (With a custom tune, etc.) I am not worried about the "tuning" part destroying my motor. (I would get it custom tuned for safe A/F and timing etc.) I am worried about the motor making more power than the pistons, rods, and bearings can take, thus trying to blow through the block!

Any ideas?? Thanks guys


I don't know who to believe when it comes to our cars and running boost. Some people say," I just installed a blower on my stock car a week ago, and I am running 15lbs. of boost with no problems!" While others say," The internals are total junk, and supercharging (even with a custom tune) will destroy your motor even with 6 or 8 lbs.!"

To answer the easy question…
Saleen S281-SCs use the stock block and currently make 375 FWHP / 415

FWTQ with their Series IV twin screw blower.
Saleen S281-Es get a built block, head work and larger twin screw blower to make 425 FWHP / 450 FWTQ

I am running 10psi on my 97gt with no internal mods, the vavle covers havent even been taken off. I have no tune and no upgrades done to the fuel system except a bigger fuel pump and FMU. I have a full exhaust from the headers back and it is a 5speed. I run on stock tires at the track. Stock I ran 14.40 @ 97. I put on the vortech v2sq and steeda boost pipe. I went [email protected] with the stock 2.73 gears and a 2.0 60ft. I feel te car is very safe and it is my daily driver.
