Pretty good, thanks for asking. Premium gas is hurting a bit these days, though. My car is still "half-assed" because I still haven't bought the sport 20 grill and bumper. Corksport was taking a lifetime to get any stuff in. So, I gave up. I'd like to follow your steps and go turbo but, I've been bitten by the SR20DET bug. That will be my project and the Pro will be a great daily driver.


FYI, I dynoed on a Dyno-Jet Dynamiter with a "built in horiba (air-fuel) meter that aids tuning". go to www.alteredatmosphere.com

Maybe the FS-ZE torque spec is measured at the wheel. Look at the Mazda Speed Pro with a 160lb/ft rating but, puts down 150-155lb/ft. Who knows...

SCC claimed that the MSP was probably making more torque at the crank than claimed. either way with 130lb/ft at the wheels you have almost the torque of a newer Spec V, which can run low 15's with **** gear ratio's (worst gearbox/engine combo I have seen in a while). Is wheelspin the problem with your 1/4 times? Can you post any dyno slips or anything? What did you do about the ECU? This is interesting, if you get around 130lb/ft of torque at the wheels with a ZE, it would be the absolute best upgrade for people with tired engines...Sorry about all the questions...

Not sure I understand the wheelspin question. I get mad wheel hop if I launch at or over 3500K. Jeremy Dehart and I get some pretty darn good 60ft times considering we've only run on the stock Potenza's. I'm running a UNICHIP piggy back which did absolutely nothing according to the dyno. It sucks because I know I'd gain some hp by leaning out the fuel. There ways to solve that but, I'm not sure it's worth my investment at this point....

One of my roomates has a scanner but, they're never here. So, it'll be a little while before I can post it up.

Sounds good, I did mean your 60 ft times I guess. And the dyno slips to see the torque curve. With that much torque I firgured with stock tires and no LSD you would sit and spin all day long. Suspesnion holding up, as well as the engine mounts? Also I thought the Unichip was programmable? Can't you adjust the fuel maps to lean the A/F mixture a little at WOT with a laptop? I haven't look into those much, I was more interested in the E-Manage, but Porsche dudes use those (Unichips) like mad. Thanks for the replies man...
