Pro system carbs

Look at this bad boy - from what I hear it may be worth up to 40hp more than the standard model. Anyway kind of neat!

Does anybody know of anybody that has this? Looks like it would be a great carb...

Re: Pro system carbs

Patrick is a frickin genious. I'm looking for a couple of tenths in the Nova so I've been kicking around making some changes. One of them..... changing the intake to a CFM fabricated sheetmetal intake. If I do,, were going to put a pair of these things on it.

Hello 8's

Why not? Could you elaborate?

I wonder if you can convert them to blow through - and I wonder if they would work on a blower.

Re: Pro system carbs

Any engine running a dual plane intake has no need for that carb. That is not a street carb.Anything short of a race car or truck doesnt need it

Re: Pro system carbs

Kinda looks like a Holley-Predator mix.

Cool looking beast, I'm a sucker for billet carburetors.

I have a billet Dambest methanol carburetor (pic), nothing runs or idles like this thing... My engine builder played with a lot of brands Willys, Stealth,K-B, BLP, and Quick Fuel (not Pro Systems,I don't think). Only down fall, cover your ass when you pay the bill...

Their first test's were on street motors.... I hope someone here gets one.


“The moment we got the prototype fired up, we installed the 1100 cfm version on a 400 horsepower street engine with a 3000 stall converter and it jumped right up against the converter instantly and sat there … dead stable at 13:1 air to fuel ratio … so we knew we were onto something.”

Re: Pro system carbs

Looks cool, it'll be interesting to see some back to back tests against a dominator style carb. Kinda reminds me of the Holley 3 barrel with that huge oval shaped "dump" for the secondaries.

Heres one on kijiji for $300 IMO about 300 times what it's worth. The 4600 series carbs didn't work out too well for Holley, or most that tried to use them.
