Brake boosting works!
So I went back to Cayuga again today for the 2nd time. This time round my car had just received the Stage 1 upgrade. 20 more HP and 32 more torque.
It made a huge difference. Last time i was running a 1/4 mile between 14.01 to 14.555.
Today I took all of your advice and brake boosted to 2800 RPM in DS AT mode with traction control off. (Temp 28c, Run flats stock rims and tires)
My best 1/4 mile time was 13.4 even.
Worst was 13.9. So two things:
1) Brake boosting made a huge difference.
2) The BMW Stage 1 upgrade makes a big difference as well.
I've basically shaved between .5 and .7 or my 1/4 time off when looking at my best and worst times. That's seemingly a big difference. In fact, I took a Camaro SS off the line. It was wasn't until the last 100 yards that he blew by me and finished the 1/4 miles in 12.9 seconds.
