My buddy installed a 10lb. intercooled blower, (rather keep the brand anonymous). Along with 42lb injectors, fuel pump, (all the recommended items). Had the blower on about 300 miles. Last night he was (street) racing a 2003 Cobra and the block let go. Got the car home, took it down and no burned plugs, no burned pistons. The motor spit out 2 rods. ANYBODY WHO IS PLANNING ON RUNNING A BLOWER ON THESE **** MOTORS WITH THEIR "cheap to manufacture powder-cracked rods" better heed this warning: THESE MODULAR MOTORS ARE NO 5.0. THEY WILL NOT TAKE ANY PRESSURE. Please do not send mail that my buddy did something wrong because he didn't. (he happens to be a master tech at FORD). Just wanted anyone who was planning on a power adder for these cars, be careful...
