Here is a little taste of handywork. It's a billet Dominator body made by BLP. Just a taste.
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.
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
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.
