VIDEO: Greddy turbo 8 at dragstrip - 14.0sec
I got my 17" wheels for autoX'ing and drag racing the other day, thread here . Made it out to San Antonio Raceway Wednesday night. My best time was a 14.0651 @ 97.68mph. My friend video taped the runs and I edited it down to 4mins (15MB). Thanks Nemisis8 for hosting it.
Video link Right click and select "Save As".
Some other info:
Temperature was 86F and humidity was also up there. Dropped the rear tires to 29psi. Car weighed in at 3180lbs with me in it (2980 for the car alone). Car number was 84.
I noticed that I shifted into 4th gear much sooner than with my 19's. I'm not sure if it's due to gearing or faster acceleration due to less wheel weight. (old rear tires - 275/30/19; new tires - 245/45/17)
I can get into the 13's by working on my burnout and launch. I'd like to spin the tires longer and have them warmer. It seems 6k rpm launches worked best for me.
The boost level drops off quickly. Peak was 42kPa (6psi) and 25kPa holding (3.5psi). I'm looking into getting a wideband O2 sensor to tune my AFR. The RP supercat leaned it out a little. Also, I don't want to up the boost (with boost controller) without knowing my AFR beforehand.

Wow! The car can do better than that!
Though your ET was almost a whole second faster, you MPH is within 2 or 3 MPH of my RX-8 before the turbo.
Your MPH (the true indicator of power) should be closer to 102 or 104 MPH.
EDIT: I now I see why (just watched it). You have practically no boost right where you need it most.
You need to fix that.

The lower ET is mostly from my other mods (midpipe, flywheel, clucth, wheels/tires) .

According to that video, when you had the video in the car, your dash showed no orange traction light to show you disabled the traction control...which means you still had your traction control system on when you raced.
Is that true? If so, how come you didn't turn it off?

Just curious, but why smaller diameter wheels? Are the wheels + tires the same overall diameter when you compare the 17" to the 19"?
