Clone carb

[Mrdavid78]

What kind of carb do u recommend for a unrestricted clone 340-375# ??

 

[mike97760]

Whatever your engine builder recommends. Its not like you have a lot of choices in clones, rules are pretty restrictive. You want a carb set to flow best with the rest of the engine.

Mold #32 is the hot thing on the market at the moment. The old “U” is the best mold for adult IMO.

The only reason for the 32 is because it’s the only one coming over here right now

The old “u” is old news .. All of us builders have already figured out the 32 , and the ones who havent are buyin 32 carbs from ones who have

Have you ever dynoed a 32 compared to a U? Or had one on the flow bench? Ive tested them all buddy. That U may be old but that dog will still hunt.

Yes sir .. i have 2 of which you have a picture of there .. Ones set up very similar to the way u have that to test carbs . The other i have set up for heads .. The “32” will be jetted slightly different but will outperform that “U” on every motor ive tried them on with an Inertia dyno ..Me and my partner are just small time builders but we do buy the carbs by the 50 case at a time .

I still beg to differ. I have a load cell dyno backed up by performance trends with the wide band setup and weather station. I’ve got a U that out performed every top carb builder in the country on a adult NKA application. I’m not on here claiming to know everything but I do know what I’ve tested and the results.

PS that bench will serve both heads and carb. I just always flow carbs on the same head. I’ll be glad to purchase one of your carbs if you provide me with the information to do so.

Are all U’s good? I’ve got one that a big name builder looked at… he handed it back and said he could do more with a 32.

How do you id the 32?

I'm wondering the same thing are they stamped with a 32 or a U?

On the head side of the carb there is a casting cavity shaped kind of like triangle. With in that cavity is a molded “32” or “U” or “V”.

I hear the V’s are good also

The Vs and U's will out perform the 32's but you will not see the difference on the racetrack.

 

[DynoDon]

Good point!!

 

[TritonJrBluePlate]

The Vs and U's will out perform the 32's but you will not see the difference on the racetrack.

How about on the dyno?

 

[DynoDon]

Very slight difference on the Dyno but not enough to see on track. To many variables and to little differences to say one is better than the other

Can you give me some specs on the EV6 pls. Lift numbers etc

I always ran @ .230 running lift on both sides with .002 preload (cold). 111.5 int c/l
