All tuned up! I did a roll on in second gear and spun the tires super bad. I tried again in third and the tires spun a little at 7800 RPM! This was on a flat entrance ramp with the QTP’s on it! It has never spun 3rd gear, ever. The spool is a little slower, from what I can tell about 200 RPM. It makes 40 psi by 6200 RPM from a 3rd roll on. I also raised the rev limiter to 9.5K. It’s been awhile since I drove it so it’s hard to tell from my memory if it’s faster. The only thing I could do is to compare a 3rd gear roll on run from last year. It is 0.45 seconds faster from 6K RPM to 8.5K RPM. With 3 psi less boost too. Hopefully the lazier spool will make for a little less of a violent launch off of the line and save the drive train a little. I’m now 100% excited to see if I can beat my personal best MPH and time, right off of the trailer!
