3/16" thick billet aluminum. 4 1/16" in diameter. Should have it in about a week. Can't wait. :kooky:
I haven't changed the pulley yet. Waiting for the final dyno tune to do that and still undecided on the headers. Only additional power mods I have so far are the open air filter, Borla X-Pipe and Borla Atak Catback. The open air filter adds about 15 hp and the X-Pipe back is also about 15 hp.nice , did you crank up the boost or is that with other mods included?
More mods the better. Quick question though. How do you factor back in your drivetrain loss? I thought the formula was something like:I haven't changed the pulley yet.

The number was a guessing game but I'm just using a standard 15% drivetrain loss. The stock ProCharger kit with the open air filter on the stock 8 psi pulley made 427.3 rwhp (502.70 flywheel hp). That was on the stock exhaust. Add in the exhaust and that's where I came up with my 510 hp number. Wouldn't that be funny if I struggled to lay down 400 rwhp?!?!? Then my custom badge basically has me committed to headers or nitrous. LOL.
I'm not worried. 9 psi with my dyno tune, open air filter and x-pipe will have me over 433 rwhp. If not I gotta pony up for more mods. A win/win!! :yup:
That and 510 hp looks so much cooler than 475 hp....:coolest
The calculation is a little different.More mods the better. Quick question though. How do you factor back in your drivetrain loss? I thought the formula was something like:
433 (rwhp) x 1.15 (.15 being DT loss) = 497.95 Crank?
Hey WRXified, if anything thanks for the link! I've been searching for custom badges because I personally think it's extremely gay to put "roush" or "shelby" or "GT" or anything else on a v6.. this however, is amazing!Thanks guys. I'll definitely post pics when I get installed.
Thanks for clearing that up.The calculation is a little different.
To calculate for instance a 15% loss for the drivetrain on say a stock V6, you would take 305 hp and multiply it by .85. (100% - the 15% loss = .85). So 305 x .85 = 259.25 rwhp.
To calculate flywheel hp you use the same formula but work it backwards. RWHP divided by .85. So 259.25 / .85 = 305 flywheel.
For me, 433 rwhp / .85 = 510 flywheel hp. I think Glenn put down 460 rwhp with his Bassani headers. That alone keeps me up at night. I'm worried about too much noise but it seems like headers are such a ridiculously cost effective mod compared to others we buy that I can't imagine not adding them.
Believe me it's not going to take much arm twisting. Another buddy of mine with the same ProCharger setup is moving to the 9 psi pulley and having American Racing build him a set of headers. I am eagerly waiting to see what he can manage to pull off at the track.Thanks for clearing that up.
Listen, you have no choice BUT to go longtubes. (listen at me spending your money) I can't say for sure when, but my dream setup consist of:
Catted Shorty Xpipe
Aluminum Drive Shaft
DO IT, DO IT!
