Hello all. On the 22nd I'm going to a dyno day with a bunch of friends. Right now my car only has a Vram CAI, and Bassani cat back exhaust. It's also a M6. I've ordered a FAST intake, TB, Kooks headers and X pipe, but I don't know if they will be here/installed in time for dyno day.
So my question is, what HP numbers do you think I will be putting down as is? We're all throwing in $20 and guessing what our number will be and closest takes all, so I was just looking for some help. I was thinking around 305. Thoughts? Thanks.
C5 of that year was 350 at the flywheel. CAI probably adds 11-12, at least that's what K&N dyno testing showed. Bassani - not much, 3-5 maybe. You may have 365-370 at the flywheel. Rule of thumb is 75% of that at the wheels, so you can do the math.
With your current mods I would expect 310 to 315 at the rear wheels. Before my Maggie install I had my car dynoed and with a Callaway Honker, a Corsa X-pipe and Corsa Cat back I was getting 320 at the rear wheels of my 04 CE.
