The carb is critical to a good working combination. I think if you make a recomendation for a brand or brew your own set up you should be required to post ET/MPH/Weight/RWHP, something measurable to compare results. Otherwise it is useless information for the person seeking to make a decision.
same goes for cams/converters...and on and on

If you want the best carb, Pro systems SV1, that is what i am saving for, proven to stomp out any carb out there this far.

I think that is the beauty of the Pro Systems carb. If you send them all of your car data/specs. they will get you the perfect carb for your application. I too at one time was shopping for a carb. And based on referrals from other racers, I went with Pro Systems. Are there other carbs out there just as good? Maybe. But I did not want to chance it to save a few bucks...JMHO.

I looked into the pro systems carbs, but part of going carb'd was the thought of learning how to tune my own. And I really wanted to keep the choke. In that sense the pro systems carbs weren't perfect for me. I would rather learn how to roll my own and not have to rely on a tuner when I upgrade.

Plus I'm a cheap sombitch. Drilling my own blanks is cheaper then buying a carb with replaceable bleeds and restrictions cause then you need a box with multiple sizes of replaceable items.

The one they quote me was $620. Thats more than a few bucks more expensive.

They do build a nice carb though. Pretty tricked out. Had a lot of features.

They quoted me 1190$ for my SV1, LOL. It will be worth it though i think.

It will work, but it will starve the engine up top.

I believe that Quick Fuel carburetors can hang right there with the SV1, and we will also custom spec a carb if you call in and give us your information.

Honestly, i dont think any 4 barrel can run as good as the SV1, it has been proven over and over already that the design is simply more efficient. But, they can hang, and 4 barrel with money and tuning can hang, but it cannot replicate the same results i think.

Nope, that was for the SV1, i think it is supposed to be able to operate blow through or NA.

If you read the blurb on the Pro Systems web site they say the SV1 is not for all applications.

If that is the case then why do all pro stock guys still run 4 barrel style carburetors? Most run a Dave Brasswell carb and we have built a few for testing but I'm not sure which one they ended up using through out the year for actual racing.

It may be a rule requirement of their class.
