... The 7mgte stock internals(or oem grade replacements) are good for 500+HP, and many in the MKIII community run 400 rwhp in their daily drivers, some in the mid 500's, a few have topped 700HP....
I have read many many posts on HP numbers, but rarely - and I mean rarely - are those posts ever backed up with any certified dyno tests. Perhaps I'm just a skeptic, but until I see some data.... .all those numbers are just HAPPY Bravo Sierra to me.
Regarding reliability of any DIYer highly modified-from-stock engine, IF I saw the numbers produced on SuperFlo engine dyno or a Mustang chassis dyno, the next condition I'd want to know is what is the mean time to failure.
Gnarls.
