Curious what most 408's are putting down on the Dyno N/A?...My numbers are horrible and I'm going to try and post my dyno graph soon...Mine is a m6, and my buddies a4 is tearing me apart and he has a 403...I know it's only 5 cubes, but the m6 should post slightly better #'s..shouldn't it?

How much power is your buddy making and his set-up? Also, what are your numbers again? Mine made 475rwhp and 508trq. But we just pulled the heads and found some major issues from valve float up top on mine. Now repairing the heads Who tuned yours?

i'd say high 400s to low mid 500s...depending on your goals.. high end race 408's probly up over 550whp. street friendly cars more like high 400s easy

ive been doing alot of research on this and from what ive seen, a strong 6 speed should be in the 520-530rwhp range. thats with a good cam, great heads and a 90mm FAST.
