Guys:

stilhead has donated $200 toward the Shootout which will be distributed to the winners. Thank you.

Cool deal, cash is nice but I will take a check also. Sorry I couldn't pass that up. lol
If a lot of carb company's don't want in and they talk the talk oh well. Everybody has a 7 sec car until they take it to the track and it won't run but 10.50's. Then the fun start's listen to all of the excuse's why it won't run. :lol:

[quote="jmarkaudio"]Here is a little taste of handywork. It's a billet Dominator body made by BLP. Just a taste. :mrgreen:

Looks like a serious amount of chips required to make a carburetor. What was the before and what is the after weight? Is this going to be a production piece? I hope it runs as good as it looks.

This is a built to order body for BLP, and throttle bore will go up to 2.800. This is similar to the stretched one Mike Laws is running on his dragster shown below, even though mixture distribution would possibly be better with one like his I opted for a standard Dominator bolt pattern as the ability to sell it if I wish will be much easier, and I am able to adapt it to my engines for testing. Not sure of the before weight, I'll have to check the after. So how many do you want and what sizes? I'm sure I can get you a good discount... :lol: :lol: :lol:

Definitely a serious amount of chips Dave. I'm not sure of the before weight but the after weight is very close to a standard 4500 carburetor and is obviously dependent on venturi and throttle bore size.

The one we run on our dragster is a stretched version and measures 2.225"V x 2.600" TB flows right at 1800cfm, depending on booster skirt size this can go up to about 2200. The engine is a 673CI, 14 degree headed engine from Sonny Leonard, it made 1385HP on his dyno on the 3rd pull, it was still a little rich and I believe we could have gotten 1400 out of it but since this engine requires new rods after 80 runs I was happy to stop there :D At the NHRA national event in Charlotte in March we ran a 6.799 off the trailer in our first ever pass, we went 6.800 second pass and got sent home with a 6.76 @ 198 breakout on the brakes in eliminations, this is a 1950LB. car with driver. If we can ever get enough time to do some serious testing the car should go mid 6.60's at around 202-204 mph. We haven't seen or heard of a faster single 4bbl. car in our class but I know there are some A/ED cars that would hand us our lunch if we tried them out.

This is a production piece, Sonny has a twin to our carb on a 762 CI Hemi that went a little over 1500HP, I don't know what type of car it's in, there is a little smaller one on a 480CI truck pull engine with the Box Ram manifold that has reported very good gains over the 2.350" TB carb he was running (we didn't build this carb, we just supplied the parts) and there are a couple of standard bolt pattern versions of various sizes running on a couple of other engines out there. So far the results have been very positive.

Rick,

The next step is to simply make a casting, think "net shape".

I talked with Gary Williams this afternoon, he is going to prepare a QFT 1250 (2.125" T/B) carb as a OOTB entry. He can't get away from work long enough to attend the shootout, so Zack from QFT will run the carb for him. His entry fee will be sent next week.

It is a very good possibility that next year there will be a 2bbl class. And hopefully they will have to pass the gauge's.

That would be awesome. A lot of circle track guys use the 2bbl.

Will the crankcase vacuum be monitored to make sure some way rich or way lean carb did not compromise the ring seal? Likewise....efforts should be made to make sure the valve springs are consistent.

BLP is also do a carb to get a base line on the engine. And after every 3 or 4 contestant's do there pull's the BLP carb will be put back on. Just to make sure that nothing crazy is going on with the engine.

Agreed. Hopefully, it will be a gauge-legal 1.375"V X 1.687"TB carb with choke horn intact and boosters conforming to CURRENT PRODUCTION SPECS (yeah...I'm talkin' to you, Old Dominion Speedway). With probably 95% of the 2brl oval-track classes in the country requiring "stock" (cough-cough) #4412 or #80583 carbs, it would make little sense to allow mods that don't fit those parameters.

Well my questions about the dyno were answered. Sounds like it'll be a great test that will translate very well to track performance. Must be fun to have something like that to play with.
