APD or Pro Systems?

#1 Post by David_D. » Mon Dec 11, 2006 3:25 pm

I'm going to be purchasing a new carb and wanted opinions on these two choices: Pro Systems, and APD.

Pro Systems would build me a custom carb using a main body larger than 750 CFM and it would wet flow 840-860 real CFM.

The APD would be built around a Pro Series HP 750 main body and would flow 840 CFM.

Anyone have anything to say about these carbs?

PRO SYSTEMS has always done a very good job for us carb has been right on out of the box Patrick James knows his stuff. Never had any experience with APD.

I'll second the vote for Pro Systems, I've had real good luck with them. On the other hand I would love to have individual cyl O2 data to see for sure how well they work. APD comes to mind more for Alky carbs?, I do know they have a good bypass regulator that is very reasonably priced.

I also use pro-systems. Patrick is a helluva nice guy and the tech support has been great.

For you guys running Pro Systems, how consistent are they? I like everything about the Pro Systems, but being a bracket racer, I'm looking for consistency vs. trying to go quicker and quicker.

Thanks for the info.

I really can't say how consistent they are never really tried to be too consistent just tried to go faster.

That's what I'm running in to. I'm having a hard time finding bracket racers who are trying to go rounds and repeat numbers who run Pro Systems (that's not to say there aren't any, I just haven't found them). Most of the people who have recommended Pro Systems are simply trying to go quicker each time they go to the track, not run back to back numbers.

I take all recommendations seriously, and that's why I'm doing research.
