Yea I know heat soak is awful. My idle times were about 45 seconds. Car would seat for about 40 min between runs with good up and cover off. Drive to lane was only about 250 feet and would sit about another 10 min. Temp at track according to the car were around 65 and it's usually off a lil. I'm just wondering if there is still a lil in the table with the tune was really looking for 1.8 or 1.7 60 foot with a 13.1 or 2 at 104. But it's close just going to need more mods. Will post the slip when I get home tonight.

Going to be honest, getting under 1.8 without e20/e30 or meth will be super hard. 1.8 is doable but it will need to be *perfect* circumstances. At launch your spark will be super low, and the heat high.. as the run begins you will get a fresh cool air shot from the throttle opening but most of the temporary cooling effect will occur after the 60' is done.. by the time your spark recovers before heat soak builds up at the end of gear-2 the benefit of a fast launch has been lost.
this is what i learned with Brad's tuning and quest for printed on slip 12's. looking at the logs it all makes sense why i was unable to get under 12's with a tune + 3bar + cold plugs + 93 octane setup.
my best non-meht run was a 13.09 .. but i *literally* set the car aside hood up ice on intake for a full hour before making one run. my 2010 spark was around 20' degrees in 2nd and 3rd so it was as good as it could be. after that i ran 13.2 and 13,3 all night @ 4600lbs.
i'd say you need to log it and look at the IAT2 temps, spark, and look for Torque source behavior.. those three control your power output quite a bit ..
