BT Time Attack Results 1:31.645 @ WSIR - Modified Class

Great results this weekend at the Redline Time Attack at Willow Springs International Raceway. It was our first shakedown since a new motor change and additional Wicked Tuning protoype suspension for the Z32 300ZX chassis. The initial plan at the beginning of the year was to pull the LS1 out in favor for an LQ9. Unfortunatly, the LQ9 we purchased had a bad cam bearing which took us out of that event. To make it to this event, Aki opted for the LM4 engine which is a smaller displacement engine at 5.4L. The lower displacement engine has other positive characteristics such as larger ports and a lighter rotating assembly. Combining this with a bigger cam we were able to rev this motor to 7k rpms which was helpful at the high speed track.

Items changed since the Ulitmate Street Car Challenge 2007:
-Weight reduction from 3400 down to 3000lbs wet with 190lb driver and 5 gal gas.
-Spherical bushing lower arms
-Carbotech xp 12 brakes
-LM4 engine tuned and raced on 91 pump gas making 350whp
-removed high flow cats (used for USCC 2007)
-APR GTC 300 Wing

The tires used this weekend were the same Khumo V700 Victoracers that were used almost wasted during the Gross Display of Horsepower challenge 2 years ago. There was some tread left so Aki opted to finish these tires at this event. With Graham Downey piloting the car, the shakedown practice laps were averaging 1:33-1:34. Ajustments made on the wing as well as tire pressures dropped Grahams lap times to a very best of 1:30 but unfortunately that was during practice. Best Time Attack Lap was 1:31.645 which resulted in 4th overall in Modified. This lap was done with a blown left rear shock and worn tires. Some of the cars we raced against should be competing in Unlimited. We'll keep sticking by the rules and shave our times. There's more glory in that :0)~
