I went to Speedworld Friday night to try for an 11 second run on E85. Didn't happen but I learned alot. It is much harder to launch a 20g car than stage 1 when I ran a 12.9.

I was spinning all the way through 1st, and smoked the clutch in 2nd a few times due to the torque. Plus the track is not that great.

Finally, after letting the clutch cool off, I was able to get a few ok runs. Best 60' was 1.77.

Best result of the night- 12.29 @ 114.65. On this run, I spun through first still. Best trap of the night was 115.24.

I do have in-car video of all runs that I haven't downloaded yet.

I wanted to post these results as I have not seen any 20g or 20g/ E85 track results for the 08+ yet, or setups that have minimal mods. I have done this on a budget and spent maybe $800 for all mods (but I self tune).

This is a perfect street setup for me, no loss in power and great top end. I also have a 91 oct map that dynos at 303 WHP, 301 WTQ @ 19 psi.

Plus, I get 22 MPG mixed driving on 91, and about 18-19 on E85.

Now on to the slips -

nice job! Congrats.

I wonder why your trap is that low. It should be around 119-120 for that kind of power.

Well, not sure. I was hot lapping all night and didn't cool the TMIC off, although it was only warm to the touch. This track sucks though. I will go back to Firebird soon but I fear I may not get great results either as it is starting to get warmer. We shall see.

I love it and had to keep the build on a tight budget. I didn't even get the injectors cleaned or flow tested (not that I recommend it).

I have a fp green 2.4 inlet 7 rear housing, external gate setup and a downpipe, stock cat back. I actually have the green up for sale but your results definitely have me wondering if i'm doing the right thing.

Heck yeah! I am trying for 11's. Gotta get to the better track and try to not spin through 1st; I'm sure I lost a few tenths there. I'll get the video up so you can see what I'm talking about.
