Hey just updating you guys. Now have the tc up to 14psi of boost and pushing 353.85 whp and 348.44 ft/lb on stock internals: Also ran a 12.59 @ 111mph to the 1/4: Videos of the 1/4 mile runs are available on www.ScionSpeed.com , check it out crazy burnout on drag slicks!!

Made 327whp on the stage 2 system. Tester is bone stock internals. Just hit 10,000 miles, which was our testing goal for the kit. That is what we were waiting on to release pricing. Although our tester is ok at this HP level to sustain over 300whp i would highly suggest upgrades like clutch...

All updates are available on www.ScionSpeed.com Pricing is now available for the kit.

Well the midrange dip you see was due to fuel pressure loss at that spot. The stock fuel pump has since been replaced. 14:1 is a bit lean for this engine under boost, but its not ridiculous. This particular engine likes the AFR @ 13:1, as evident by the torque peak at that spot. Any good...

If you look in the background of the clutch pic, you can see the rear engine mount is now polyurethane, hopefully this will take care of the engine movement completely. We will see when we get back on the dyno, so far it feels alot better than it did.

forgot to update you guys new dyno new twin disc clutch and flywheel new limited slip diff The stock clutch was slipping badly at 12psi, so had it upgraded and upgraded a couple more things while i had the tranny out. We are planning a trip to the track, so will post 1/4 mile times this...

Yes I am the owner, fabricator, and tuner of the white tC. I am the owner of www.ScionSpeed.com (DBA: Jamasco Race Engineering Inc.) Thank you for the compliments

Well i had it up to 14psi last night and its still going. I actually got it running alot richer so its safer than it was before. @ 14psi it was running a steady 12.6:1 AFR, and it seams like these cars like it at 13:1 so its good. I am a Toyota tuner so from experience i know that the Toyota...

actually the TC puts out over 265 @ 7psi (both dyno charts are posted) and this is running pretty lean, not nearly done tuning yet either. so I wouldn't call it even, maybe close. would be more like Scion: 2.4L turbo @ 7psi = 265whp Mazda3 2.3L turbo @ 7psi = 245whp but then again the...
