It just occured to me, Does anyone see an issue with the way I have implemented this? I am thinking I may potentially have an issue with fuel bleed off out of the accelerator pump circuit which could cause a hesitation. Is there a check valve in that circuit?

Disregard, forgot about the check valve below the squirter.

Hey All,

Got to do some testing tonight,

Good results, Car was approximately .01 faster in the sixty and .03 faster in the 1/8 in about 1000 foot worst air. Still needs some work

Here is the url to a larger pick

As you can see from the pic, it leaned up the afrs on launch from 10.5s to 11.6s. Also notice too that the flash stall rose approximately 130 rpms. That lean spike is from me playing with different squirter sizes and did not effect how the car ran. I went from a 37 squirter to a 28 squirter and it had that lean spike, but the car still ran the same. Just shows my car likes that initial shot of fuel. I race tomorrow so we will see how she does in the heat of competition.

That is manifold vacuum, I just have the wrong label on it. The data at the right is at launch rpm. I hid a bunch of stuff on the graph so it wasn't so jumbled.

Forgot to mention it in the previous post, but also notice how it holds the g-force higher after it peaks compared to the other run. It definitely appears to have improved power based on the g-force and stall, still have a little more leaning.

Well made it to the semis before turning on the red bulb.

So far really happy with things. I plan on putting back on the stock dominator pump cam. It has a little hesitation when coming up to my launch rpm, logger shows its going lean, so i think with what I have done with the cam and the bleed is take too much fuel away up front. So we will see what happens. I would expect to have to put a bigger bleed in there as the current bleed is pretty close for the current pump cam I have.

I will be able to test one more race, unfortunately, got a short notice tasking, so I am deploying out again in 3 weeks.

Bill, that thing (pump bleed) will work in different ways depending on how you hit the throttle, ie, slow apply = less fuel, quick apply = more. You could probably take the pump arm completely off and still get to your stage RPM with out a stumble. Why not try a smaller bleed before you go to those monster cams. You won't have to change much just to use a smaller bleed and that may take care of it since it's so close. If you change the cams, then you're back to square one. :-k

I will give it a try, never had much luck drilling bleeds that small, usually wind up breaking them.

BUY A SET OF .015s! Can't cost that much and if it's too small, they are easily opened up! ;-) That will save you the cost of the drill bits. I've successfully drilled them to .018 but it wasn't fun! O:)

I actually bought one of the little drill press for a dremel tool, when you get that small, it is so easy to put to much pressure on there and break them. Was about to order an assortment from BLP starting at .014 up to .026. I was just trying to figure out the deals with the float bowls.
