thasts what I was leaning towards sam.. a 75 dry shot for a little off-the-line.. oomph
I took your advice and went ahead with the two stage setup, featuring a dry shot off hte line. But I was being a ***** and only went with a 50-shot on the dry stage. I did it a bit differently too... I have the nozzle placed before the MAF. So it sprays across the MAF and "freezes" it, thus spiking the vontage a bit and making the MAS think more air is flowing in. So it adds extra fuel to compensate for the colder sensor. That way I can have a dry kit with no worries about spiking the fuel pressure or anything like that. I was a bit scared at first, but I did some short runs and it works like a charm. AFR is right on the money still and there aren't any lean spikes, not even when it first engages. So now I get a little extra boost off the line.



As you can see, I even tried t semi-hide the line and nozzle. Anyone with a clue should obviously know what it is. But I figured that if I cover it in tubing, it won't draw any attention towards it in a quick once-over. Of course, I could have completely hidden it in the fender, but I wasn't going to put that much time into it.

I haven't run it all out to actually use the old second stage though (which is wet.) I'll do that when I get to a dyno in a week or so. But I definitely like the idea of the extra dry stage.

Well, I just picked up a Pro M meter and 24lb injectors, then I decided to go build a turbo set up and was wondering if I should sell the 24lb stuff and go bigger. I wish I would have decided a week earlier.....
Turbo? 24# injectors? Ain't gonna happen... not without an FMU, which pretty much defeats the purpose of buying the 24# injectors anyway. If you're planning on a turbo, then I'd suggest 36# or 42# injectors and be done with it.

I didn't buy the 24's with the turbo in mind, that came after....I guess I will be on the look out for some bigger ones.
