Re: Sneaky nitrous

Mmmm, ok. So I can just essentially plug the other 3 holes and run the direct port in wet kit fashion? That would be nice, like you said, to get used to the nitrous. So when this all happens, I shouldnt have to adjust AFRs in DSMlink should I? Unless I am mistaken, the direct port is like 4 wet kits so the fuel should come from with the nitrous through the nozzles right?

Man I am such a noob.

The direct port kit I found is complete except it needs a new bottle to solenoid line. Well there is a guy also down here selling his wet kit complete except he doesnt have the electronics (I think). I think I may buy both systems to make one complete, plus I will have two bottles which will be nice if I burn through it quick, and I can sell the remainder of the wet kit if theres anything left to sell.

EDIT: Ooop, just found out that its a NOSzle system... that means rather than the standard Y looking nozzle, the nozzles are built so that you plug the injector into them, then plug the injector/nozzle assembly into where the injector is supposed to go. I was a bit sad that my incognito thing would be blown, but after looking at the pictures, it shouldnt be too hard to cover up. Rather than mount the solenoids on top of the mani, I can mount them underneath to either the firewall or where the manifold "stay" or whatever the fuck that gay bracket is called used to be. I can then just turn the NOSzle sideways inwards so the lines just run around the side of the IM runner. Then to cover the NOSzle I will just make sure that part of the wiring harness gets in the way! I cant remember right now if it does or not, but an oversized loom and some zip ties should fix that right quick. I think this is the right way to do it too, no fucking around with tapping the IM and all that.

I did a little looking and Holley suggests that with the 75 shot direct port thing that you use a 22 jet for the n2o, a 14 for the fuel, and you run 2-4 degrees timing retard. Does this sound about right? I assume that the 22 jet is the same thing as the .022 right? It does say that its adjustable down to 50, but I cant find jetting specs for it. Oh well, looks like I am going to have to start with a rich tune to begin with, then pull a few more degrees of knock than is necessary, cross my fingers, and give 'er fuckin hell, right? I figure if richen up and take out some timing of the DSMlink tune to start with, then rather than take off 2-4 degrees when it engages, I will have DSMlink take off more like 8-10 or something just to be on the uber safe side for the first run just to make sue I dont fuck something up. I can then do trial runs adding fuel and timing to the base tune to get it back to where it should. Then provided I havent run into any huge problems, I should be able to start taking a degree or two off the nitrous activation control on DSMlink until I am safely not knocking. Is this the right idea?
