What Throttle Stop to use?

[sst5167]

I will throw my .02 in as well.

I will agree with just about everyone here, Gary with #1 Stop is just about as good as it gets. For many, many years we had #1 Stop and Stinnett carbs on our super gas, street, and comp cars. They all worked great! And Gary's customer service is great as well.
A couple years back, when APD came out with there Max Speed throttle stop carb, we bought one for the super gas car to see how well we liked it. What we found was, it layed down on the stop just as good as the #1 Stop, but was about 3 mph faster. For that reason alone, we now have the APD Max Speed carb on all 3 cars. And all 3 have sped up between 2-4 mph. To me, that is easy hp. One thing to remember on the APD is to run them EXACTLY how John and Joe tell you too. They know what they are talking about, and there customer service after the sale has been wonderful.

In my opinion, you can't go wrong with either throttle stop setup. Both work well enough to win races and championships. And both have great people to work with.

X 2 on the APD Max Speed, love mine and like sst5167 said, listen to what John, Joe or Randy tells you on setting them up and you won't be disappointed.

I hate to admit my stupidity here but I put the APD Max Speed carb. on my Super Gasser two years ago and I still can't dial the thing. It really doesn't dial any better than the Quick Fuel carb. using an in-line stop. Obviously, I'm doing something wrong.

Do you have any kind of data acquisition, or playback capability? If so, how well does it lay down on the stop?

Thanks for the reply. I haven't been here for 5 months, so my response is slow. I have a Racepak and it looks great on the stop. Typically 3850 rpm, dead flat. It seems the the consistancy issue is further down the track. This year I am trying a disc stop with a Quickfuel carb. One of the problems with the APD was throttle response. It always had a lag getting up to stall rpm (5800 on chip). This would result in inconsistent reaction times. The Quickfuel is not as flat on the stop as the APD. I have to play with either carb closing speed to prevent a "droop" when it goes on the stop.

Usually, a "droop" when it first goes on the stop is caused by either the float levels set to high, or the throttle stop closing speed is to fast. You do not want the throttle stop to slam closed. Slow the closing rate down, and I'll bet your droop goes away.
