Thats all your opinion but we know what we are doing so thats all cool and its a m5r2 btw the block is not going to crack at 500 horse and your blower should be screaming at 8 psi cause supercoupe guys can pump theirs up to 16 easy.
This statement has proven your ignorance/youth.
You do not understand the concepts of CFM, It takes a TREMENDOUS amount more airflow to keep a V-8 at 8PSI compared to the Super coupe's V6.
Are you going to believe some guy in New York, or a guy that actually factually HAS A M90 roots blower on a 5.0 with similar specs, and has been dyno'ed.
Go find me a 5.0 powered ford ANYTHING with an M90 ontop with a stock long block that makes more than 450hp and I will eat my shoe, film it, and put it on youtube.
A stock 03-04 mustang cobra makes 390hp at the crank, and that is with a much more efficient M112 blower, and a far more advanced engine right out of the gates. If an M90 could make that kind of power, why did they bother using the more expensive, more advanced M112?
This isnt any engine guy he lives in new york and is the number 1 recomoned tuner by everyone he travels around the world tuning
Think what you want, but I've never heard of them, but stock 5.0's do not take that kind of power kindly, nor will yours make that much.
