Has anyone ever done back to back testing between a 2inch throttle bore and an "Outlaw" no restriction Dominator? This of course would be a N/A application. Just looking to see an approximate et reduction.
Calvin,
There is No way to give anyone a REAL world YOU’RE car will pick up X amount of ET, MPH & HP switching from a 2” Butterfly carburetor to what you classify as an “Outlaw” larger throttle bore carburetor. There’s no way of knowing over the internet how optimized your current combination is, and then what are you going to compare it to, and how optimized that combination is going to be (i.e. will you be making combinations changes to optimize the larger carburetor).
Dale builds a great piece, but you’re going to tie his hands if you’re requiring him to utilize either a Demon, or Holley casting.
Looking at our B-7395 you can still utilize a standard 5.38” x 5.38” bolt pattern, but that’s pretty much where the similarities stop. The metering circuitry is designed so that it will not uncover the jets like these modified carburetors you’re looking at. Plus the castings are going to be substantially lighter than the cast Holley or Demon or heavy Billet bodies. So it’s really all about how fast you want to go, and what you want to do to get there.

Calvin,Sorry...yes there is a way. It is called back to back testing at the track.
Sorry...yes there is a way. I know my combination is optimized to use the bigger carb or I wouldn't have asked the question.
Sorry...tie his hands...fuck off asshole. It is what I have to work with. You call him up and tell him his hands are tied every time he builds a Holley carb.
Sorry...I didn't asked does someone had a lighter carb than a RS Demon.
You're as bad as the ProSystems porn representative that is in every carb thread.
My .02 for the puke out the side of your mouth.
Since you know you’re combination is optimized why would you even need to ask the question? But more importantly what size carburetor is it “optimized” for? Will all combinations use the same “Outlaw” carburetor as you call it?Has anyone ever done back to back testing between a 2inch throttle bore and an "Outlaw" no restriction Dominator? This of course would be a N/A application. Just looking to see an approximate et reduction.
And yes you’re tying Dale’s hands… It would be the same things as taking a set of CI GM cylinder heads to (insert name of whatever porter you’d like here) and asking him to make them the best thing since sliced bread you can only do what you can do. When Dale was working with some of the Mountain Motor Pro-Stock guys did he start with a Holley® casting? No he started off with our castings because he wanted to actually be competitive.By "Outlaw" I meant maxed out standard bolt pattern.
I was just curious the performance difference between the 2inch Pro Stock legal version and when we switch to the Outlaw one.
A bit harsh? Calvin, there is no way anyone can say for sure with the lack of info on your setup what you might expect. May be two or three hundredths, may be a tenth or a little more. It might slow down. I've run a 1250 on my SB2 and it was faster than any of the smaller Dominators I tried by almost a tenth. At some point I may try something bigger, but for bracket racing it's not as important to make small gains. Finding what size will work best, well as you said back to back testing will tell you that. While Braswell make a quality carb that has won plenty of Pro Stock races, it is not the only one to do so. Doug's job is to sell Braswell Carbs and that's OK, just like Book, Cubic, BLP, APD, Quick Fuel and others do. The fastest carb for you will be the one that supplies the least restriction while still metering the correct amount of fuel in the range and conditions you run in, and atomize the fuel small enough for the requirements of your engine without being too small. You can have two identical sized carbs, and one be faster than the other. Changes in boosters, passage sizes, emulsion, and bleeds can make one different than the other. With the right stuff you can do it with a Braswell carb, a Quick Fuel carb, a Demon carb, or a Holley or Billet Holley style carb. With the wrong stuff any one of them will fail.
So what is it going on?
As I said best of luck to you in whatever you choose to do, wasn't trying to sell YOU anything at all, just explaining some of the options out there.If I would have wanted your Sales pitch I would have called. My post was understood by those who weren't trying to advertise "their" carbs.
