[QUOTE="blowngt, post: 7036981, member: 12951"] First 2 runs were a pair of 11.20's on 11#s - 126 The last run was 20#s and went 10.67 - 138. 60' on all 3 runs were in the 2.0's...... All were on saleen 18" rims with 295-35 Nittos. [ame="http://www.youtube.com/watch?v=fwgP7MkZWqc"]YouTube - Moroso[/ame] I turned the 57's up to 23#s a few weeks later and went a best of 2.061 7.189 114.43 - MPH 9.036 - 1000' 10.700 128.05 - MPH On that pass I actually was hitting the rev limiter so I had to coast thru (26" tall tires and a 3.31 rear weren't enough). I'm guessing it happend right around the 1000' mark. In my quest for 9's on 18's I hurt the engine (dropped a valve seat) so I took the opportunity to upgrade the turbo's to 61's while everything was apart. I should have the car back next week, but I'm probably going to wait for some better weather before I go back out. I maxed out my 57s on the dyno at 25#s. The car was surging on the dyno, so we decided to back it down a couple of psi to be safe (at 23#s it still made 780 thru a 4R70W). I guess it wasn't safe enough seeing as the IAT temps (on the run where the valve seat came off) were in excess of 170*. Moral for today, don't max out the turbos. Bad things can happen......
