I did not have ANY good experience with Pro Systems carbs. I went to AED and had very good luck. I now am getting ready to try a Thumper carb from Dominic and the reviews and testimonials I have read on Thumper carbs...is second to none!

What kind of money are the Thumper carbs?
I got the feeling from his FB page that if you have to ask, you can't afford it.

Billet bodies, base plates, metering blocks, custom annular boosters. They flow over 1000 cfm each. This pair from Lightning carbs, $1900. You can call him for tuning advise or problems anytime.

Throttle plates are 1.75". Main bore is 1.60" if I remember correctly. The boosters are special type he specs. They have 24 outlets. He says they flow as good as almost any down leg he's tested. Dry flow is around 1100 CFM.
