I was hoping to break into the 10's but I'm very happy with an 11 flat and my previous run was an 11.07. I only got three runs and this is only my 2nd time at the strip. I'm planning to get back again with a few changes to the tune and hopefully some quicker shifting for a pass in the 10's to the finish the year. I'm limited to 27-28 psi of boost right now as that's all the injector duty I have with using FIC 2150's to compensate for running out of fuel on the Walbro 400. Once I get a big pump setup, boost will be turned up to the 30's and I'll go back and see what that can do.

So close to 10's! Should have made just one more pass!

I just watched the video. I really like the quality. Was it a GoPro? I had my dash cam setup for a shot like that but the memory card was full for my drag passes

I did have it on for the roll racing, but the quality isn't nearly as good as yours. I'm surprised how well yours did getting the interior and exterior to be exposed properly.

After watching the video I think you just need to pound those gears a little harder and you'll make 10's for sure. Your 60' and your trap are both better than mine.

Great job man. That's a nice 60'. You have 10's easy with some quicker shifting!

I know lol. It was kind of fun being about as close to a 10 as possible without getting one. I thought about making another pass but we only had four trailers and three were occupied by this point. Mikey broke all the spares he had, CJ toasted his clutch, Doogie broke a rear axle on the LGT making a second pass with boost on the line and JR was still playing with the RS. I decided to quit while I was ahead and start drinking.

We're gonna go out again on a cooler night with some adjustments and go for 10's on my car and the LGT. We're both right there.

Thanks! I had it building about 13-14 psi looking at the logs and I was at 5500 for LC. My rpm dropped to 4000 on the launch but boost carried from 14 to 22 (I had first gear limited a bit for better traction) and it picked right up. I think a little more rpm and boost and it would leave perfect without the slight bog.

Also impressive, the logs show I started the pass at 99* F and only got to 113* F by the end of the run. I think that says quite a bit about the the efficiency of the ETS FMIC I am running.

Yeah - its the Hero 3 black, filmed at 1080, 30 fps. I simply trip down my videos with avidemux, leave them in mp4 format and upload right to YouTube. The mount is this one:
http://www.amazon.com/gp/product/B003ASPH48/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1http://www.amazon.com/gp/product/B003ASPH48/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

A friend suggested it for less shaky videos and not needing to use the YouTube stabilization which makes things look weird to some people. It does work a lot better than the standard mount GoPro makes, at the the older one I had.

Yeah, like I said, I know its right there. The Competition Twin is new for me so I'm still getting used to it a bit and getting comfortable with my quick shifting. I didn't give me any issues on the last two passes where I used FFS. I'm sure it can take a quicker shift if I can get my timing right. JR gave me a suggestion to bring the FFS limit up a lot higher than I have it so I am going to try that as well and see if that eliminates some bog between shifts that I think I am feeling. I've always set it just below where my shifts land in the rpms thinking that's the best way to do it. I can see how higher might be better so fuel is cut for even less of a time period.

Thanks man!

Did you ever get that Dom 3.5 turned up on your car?

I had mine maxed out before selling it for this new setup. I was peaking it at 30 psi, tapering to 26 by 8000 and it felt very quick for a stock location setup. Never did get it on the dyno to see what it was making though.

I have a Hero 2 and a cheap dashcam that I use for my in car videos now. But I edit with Windows Movie Maker and it just crushes the blacks when converting to WMV (which is requires you to do), so the videos always end up looking really dark. I just downloaded that editor to try.

I believe I actually own that mount for when I was using my Canon G12 for in car videos. I almost never do that anymore though. I also don't have a tripod mount adapter for my GoPro. I may have to try out some new things in the future. I haven't spent too much time on it.

I don't have any FFS software of any kind on my car. I just shift as fast as I can and the car pulls hard the instant the clutch is released. But mine is just a single disc (unsprung 4 puck) so it grabs really quick. I wish I had a twin or triple disc for off the line, much easier to control.

Not this year. Car has a boost leak and I am crazy busy, no time to deal with it yet. The car is out of MAF at this point. I am thinking about FMIC/SD conversion over the winter and turn her up. Definitely quick as-is on 93 oct.

Sounds good! Those changes will make a huge difference, especially on the top end.

Thanks! I'm very impressed how well this turbo is working even at a lower boost level.

I thought I'd need a snack before racing but I never got to it. It was a nice find the next morning on the hung-over drive home.
