I knew it wasn't true since the BradH I know would've ordered one in each color. So I wasn't fooled at all. One polished, one with the anti-corrosion block coating... would make nice bookends on my parts shelves as they gathered dust over the years.

I'm a fan of Pro Systems, but I'm skeptical. Kinda like the SV1s were...looks cool but the performance was, meh. New designs/variations are a good thing though.

Doesn't C&S already have the patent on that design? Not sure how Patrick gets away with that. More CFM with a smaller venture because the booster is not there. Looks interesting, but I don't hear anyone saying how good the C&S carbs are and these look to be very similar. IF C&S has a patent, it's probably on such a specific feature that anyone can design something functionally similar w/o infringing on it. FWIW, I've heard very mixed comments re C&S stuff. IIRC, more positive re alcohol applications, not so much for gas. Look pretty friggin' kludgey to me.

Brad: we have a 1200 on a 440/512/indy head ( 440-1) , wilson modded indy 4150 intake , little 625/270 cam/727/4.56 car- runs 6.37 in good air. The twin blade picked up the bcar a lot over the 950 it had before , its been just deadly consistent . The thing with the twin blade is that it gets up on the boosters at pretty low rpm and does so quickly so, pump shot/squirter tuning is a bit more critical on pure race cars - don't want to leave too rich. Dom set this one up for us, not the guys that sell them and we haven't had a lick of issues. All we had to do was final jetting and i think one high speed bleed change and Dom sent enough bleeds to go up or down two steps if memory serves. Engine is a lot HAPPIER,
Is it as good as a Dom? I don't think so, could probably drop some numbers with a Dom , however, this class only allows a 4150 flange carb so, its certainly a way to get more cfm if needed and, we needed it . Vacuum numbers at wot are much better with the twinblade than they were with the Pro Systems 950. Its a good carb , no issues, no crap parts, very good metering blocks and even those are better now.
I will have the duster done soon and plan on doing a back to back with it and a 1050 from Dom on a similar 512 and see how close they really are.
I can say, without qualms , if the car needs more carb and your limited to a 4150 flange, the twin blades definitely help. I think they can get as large as 1450 cfm, heard rumors they have a body that will now do 1600 but have not confirmed that.
if your looking at one, let me know, also, you can get them with Dominator style boosters.
