Whats a good AFR to shoot for with both?

Between 11.0 and 11.5?? Right now, mine is between 10.0 and 11.0

 

A little fat, but safe. You are probably leaving a few ponies (10 or so) on the table. 11.5 would be perfect on the juice IMHO.

 

I realized I used the old Jet numbers. 52/31 for my 100 shot.
Guess I can try 52/28

 

Out of curiosity, what's your AFR w/o the spray?

11:5 - 11.8

 

Put the 150 shots in. See what she will do. I will tell you this, we had to put the 100 fuel pills in for my 150 shot. My fuel system is working big time. It was really hard trying to lean her out on spray. We put the smaller fuel jets in and it worked great. I`ve got 255 intake, T-rex in-line, 42lb inj, and fast fuel rails! Put the 150 jets in and leave the fuel and test it out! Let us know!!

 

Geez ED--nice numbers--I'm about to do the same as you,I did the nitrous install just waiting to dyno--You could lean that a bit, but on a cool day,outside of the dyno room you may be a bit leaner anyway--if you have a wideband AFR meter I would wait since you know your safe now and see what you AFR is at WOT out in the real world.It may be leaner.I noticed that my AFR's are a bit leaner on a cool morning.

 

Thanks guys. I really thought about the 150. But didn't want to get too greedy. I just wanted to break 600.

But I am sure I will want more. I am looking into making mine a dual-stage.

 

It's a completely different engine, but I run 10.9/11.0 with 14#'s of boost and a 185 shot (with only 17* timing). I plan on upping the shot to a 225shot to get 11.5 a/f (I am running a dry shot, AFTER the maf meter, and alll the way starting from a 50 shot, for every "50 shot" increase, the a/f leans out by 1/2 point).
