I finally got around to running my Supra down the 1/4 mile yesterday. It's now running ~18psi boost with a fuel cut defender and a bleed valve, so it feels goddamn fast on the street. I just wanted to find out exactly how fast! I ran it on the dyno in the morning and got 302hp at the wheels, so that suggests a 12 second pass, depending on traction and driver ability.
Anyway it was a busy meet so I only got two runs in before I gave up and went home. The first run I bogged down badly and hit the rev limiter a couple of times, but the raw horsepower saved me from too much embarassment - 12.997 at 114mph. Just scraped into the 12's, woohoo! Needless to say I was very impressed that the car ran a time like that even after I botched it so badly.
The second time around was much better - I used a lot more revs off the line, and kept a better eye on the tacho. I had to back off a bit in second as it started axle tramping, but apart from that it was a near perfect run. I recorded a 12.49 at 117mph! Pretty damn impressive stuff considering I'm running the standard engine, turbos and ECU. I can't help thinking how easy it would be to get into the 10's (big single and management should do it), but that's a lot of money...
So there you have it, I've proven that I have a 12 second car. I doubt I'll take it to the drags again though, I just did it out of curiosity. Next on the upgrade list is a TrueTrac, suspension and brakes. Methinks the engine has been upgraded enough already.
Oh yeah, I should have pics and vids soon... stay tuned.
