I think I do.

Had the frame straightened and then cut out and put an all new 25.5 cage setup in it which totally got hear feeling solid.

What system are you using to control the fuel injection?

Im using a FAST XFI to fire the injectors and control all ignition functions like timing and so on. I use an MSD 8+ to purely deliver the spark.

2012 is over and I am working on my 2013 upgrades. Here are a few videos testing some intake we had. There has been no tuning changes for these. I am just running my program we ran at the Halloween Classic. Pulls are on the engine before we tear it down so this is after a full season of racing on it and of course it got beat up a but as I learned how to turn it on Methanol this year. I had some runs this year that broke the porcelain and ate the electrodes off almost all the plugs and she still runs fine! You can read the video descriptions to see what setup we had on it in each pull.

902HP @ 7500 spun it to 8500 where it still had 852HP

Nice numbers, pretty strong still at the end of the season. Do you need/want more power, can you put it all down to the ground now?

I want and need more power. I really need to be north of 1000 so we will be making some changes.

I don't really have issues with traction but I am having TC issues trying to get the stall I need and the RPM shift drop is killing me. I had a real chassis shop look over my car and the think I have .2-.3 left on the table just from chassis issues. If I get these fixed and get some more power I should be where I need to be at the very bottom of 8's hopefully.

Almost ready for this year. Not too many changes from last year but I like what we came up with. Peek power isn't peeky at all. Pretty much the entire range my car will operate at looks to be peek power! :) I should be taking off around 7300rpm and shifting somewhere around 8500 depending how the power looks up there. We only spun it to 8000rpm but you can see we are off peek but not really falling off at all.

TQ is pretty flat across the board.

Dyno run started at 5k where it was 612 and ended at 8k where it was 609. Peek was 690 at 6200rpm and held strong with 662 still at 7300rpm. Started really dropping around 7700. The power seems really good and should work good to get the car down the track.
