Technical Information regarding SQR23DE-T

Quoted from Travis- (I forgot your TR screen name, sorry bud )

"Charles' car made 500.6whp tonight, at 19.5-20psi. The spring in the wastegate prevented anything higher than that.. Going any higher on teh duty cycle on the E01, resulted in erratic dips/spikes between 17-21psi. It was able to be dialed in to 19.5-20psi, with only 1/2 a psi fluctuation. The spring in the wastegate is simply too small. He's going to get a bigger spring for the wastegate, and try for more power in a couple of weeks.

All in all, the car made mid 400's on pump gas, and probably could have gone up to 500 on pump.. but, playing it safe, leaded race gas was used on the last few pulls. Timing was at 23-24* total advance, and A/F was a safe 11.2-11.4:1. To show how durable this engine is.. the car made 60+ dyno pulls today, and was on the dyno for about 12 hours. Water temps never got over 208, even after several back to back pulls. Heat soak with the intercooler became a problem though, so cool-down's were set between few runs"
