I put out 586 w/o water/meth and 616 with 30% mix. Stock Cp3 and sticks. I would have used my modded FCA but I loaned it out and did not get it back before the run.
SPS62, TNT#9 4/2/0, and MP-8 100%
I tried N2O and it made the turbo spool 500 rpm sooner but lost peak HP. I need sticks and CP3 for the N2O to work.
