PB @ West Coast BOTI
Well, I had a great day today at the Boti finals here in Cali. I made it to the semi finals via a red light and came in 3rd place overall in pro stock. On top of that I scortched my old PB and ran a 12.07 @ 109.45. I treed the Honda but he blew right by my little 12a. Not too shaby for a bone stock chassis 4door rx2 with a 12abp on 91 pump fuel. That's got to be a record of some sort eh? hehe. Here's the run down and video.
R/T- .143
60'-1.537
330-4.811
1/8-7.583 @ 88.43
1000-10.011
1/4-12.070 @ 109.45

I was there spectating(wish to race).......there was a few more rotaries but most of them ran time trial.
Jay was the only one competing in the all motor class,his car looked good out there and beat
some of the fast honda's with bucks.
Good runs JAY.

Thanks everyone. I had a really good time and that's what it's all about.
There were a few other rotaries like Rene mentioned but they were running in
the fun runs. Chris was the only other forum member racing that I can recall and I think he ran a 9.6. I'll let him confirm that.
Next year should be alot better and more cars. I know Rene is going to be ready and I will be unvailing a new setup.

Yes Ujay but the forth pass the trans brake did not work.I always do my burn out in second gear but this time I clicked it into third,ran it up to about 7000 in third, when it came out of the water box it chattered the tires real hard.I think one of the wires came off inside the trans pan.I going to take the trans pan down in about an hour from now.I am going to barona this saturday to see if I can go 5.99 in the 1/8.in the forth pass I just rolled out and it still went 134 MPH

If you don't already have one, buy a 3.3 glass ball needle valve from Jaycee or Gene Berg, and extend your float bowl internally. The glass ball needle valves will hold 8-9psi depending on float level, and flow much more than the usual 3mm. Also, drill the inlet above the needle valve to a larger size, at least 1/4.
Is your car geared for the 1/8th? Maybe that could affect your 1/4 performance some.

My car is geared so that I'm in my powerband after every shift, but since I am running a stock TII trans. 4th gear is 1to1 so I think that will slow me down a little but I might be able to use a little more gear.
What would be a gearing for 1/8th mile vs 1/4 mile?

Ok then, if you are definitely draining the float bowl you most likely have a fuel delivery issue - e.g restrictive filter, tank pickup to small, fuel line too small, pump can't keep up, fuel pump on it's last legs, etc etc. Are you using a dead head style fuel reg or a return style? I suggest return style as the Holley dead head regs can be restrictive. You can turn the Holly regs into a return style by removing the check ball and spring and plumbing it up backwards. If you do this the return fuel line needs to be the same size as the feed otherwise fuel pressure may be too high.
The other option is to tee another fuel line into the existing one and plumb it into the float bowl drain plug via a solenoid. Wire the solenoid to a full throttle micro switch so it only feeds into the float bowl at WOT. Regulate the flow with an old weber jet stuck in line somewhere.
I've never raced 1/8 mile but for 1/4 you ideally want to be crossing the line tapped out in 3rd or 4th, not half way through 4th, or pulling 4th just before the line. If you can't get it right with rear end ratio's you can change tire diam, hopefully without affecting 60ft.

Edit: 1 more thing- if you run a dead head style reg and have any sort of fuel return running back to the tank, block it off. That would likely be your problem.

What about a scoop jay......you had a scoop before you added the carbon hood.Cut that **** up,its only carbon fiber LOL.
My all motor car made a huge difference making a better hood scoop,I think your car is running out of breath under that hood.More air and fuel more power..
