Tonight after work I wanted to run my car out to the pretty much vacant Cty. Rd and do some more 0-60mph runs since i had a few more gallons of straight 116 oct. in the car. I made 4 good pulls and each one was better than the previous. I never thought the car would launch so hard that it would break loose and twist a bit sideways.
The 5th and final run I get out on a cross road a little better shape. Pretty heat soaked, intake temps at 100* and coolant at 210*. I wanted to do one last launch. Each time i was adding a bit more timing, more boost and a little less fuel. Probably still rich for race gas but safe. I was about 11.9:1 on dsmlink. Boost gauge showed around 20.5psi. Still low for what it should be but... i'm tuning. Don't want to go too far all at once.
So i lauch it and dam it launched hard. My amp and speaker gave loose and got slammed up against the tailgate area. Dsmlink shows a 0-60mph of 3.56 seconds. It was pretty dam good so i stayed in it and decided to 1/4 it. I ended up running a 12.72 et on gtech. Dsmlink shows a bit better than that but lets just say it's a 12.7.
Where i need the opinion:
My rev limiter is set at 8k rpms. 7bolt 2g motor. At the top of 3 gear a bit before the 1/4 mile, i started to bounce off the limiter for about .25 sec which hurt et a bit. Let just say this is a 12.0-12.5 right now as she sits, based on that..would you guys up the limiter to about 8300 and stay in 3rd gear or keep limiter where it's at and shift to 4th. I just don't know the rpms limits of the 2g. What's your experience on shifting? Stay 3rd or goto 4th.
DAM she felt good!!!
