The 4412XP race series carburetor is a good compilation of parts with a generic tuneup in it, so there is plenty of room for improvement in power and drive ability and still be legal.

Just like on our 4412 non XP carburetors we have been building for decades, correcting the fuel curve and maximizing air flow with mods that straighten the air to improve flow YET WILL STILL pass GO-No-GO gauges is what we are all about here at PRO SYSTEMS.

If needed, we even take the time to heat the body in oil and pass a large bearing through the body to STRETCH the body to the maximum size allowed without making a mark on it.

So if you are looking for maximum power and fantastic drive ability from a 4412XP, we have you covered!

We offer designs for Gasoline, Alcohol and E85, even versions with our VENOM II billet metering block, thinned shaft, raised boosters, over size venturis and more… just a plethora of upgrades are available depending on your rules package or how far you want to push them.
