Hello all. Show and tell time.

I used to have a ZEX dry kit jetted for a 55 shot. I loved it. It was my first experience with a serious power adding mod. I then went with a V2 SC and the new fuel system didn't jive with the dry kit. So I promptly sold the ZEX kit.

Quite a while later (while still supercharged and seriously lacking low-end torque) I assembled and installed an N.O.S. direct port Pro Fogger kit. I say assembled because N.O.S. didn't sell a 6 cyl kit that I could find. I found a killer deal on a new 4 cyl kit and went from there.

BTW: if anyone is intersted in getting your intake modded to accept annular nozzles, PM me (someone asked me about it already so I thought I would throw that out there)

It's jetted for about a 75 shot right now.

There are a few more pics on my homepage.

After I installed it all I can say is, "WOW. This thing pulls hard."

that's a tight setup. i'd like to do that someday. do tell how you made the bungs on the manifold.

great job!

Thanks

Actually, the only thing on the nitrous system that I didn't do myself was the welding on the intake. So, I can't tell you much about that part of it. There's a guy in the area that is a wiz at TIG welding aluminum. All I can say is if you want one, send me an intake (and some money of course) and I can have him modify it and I'll send it back.

hmmm...I've always been interested in checking out a direct port set up.

How do you figure you've jetted the fuel on a DPI kit down to a 75 shot?

Even if you use the .014" jets it will still be well over 125hp worth of fuel with 6 jets at 3.0 BAR.

I've got .012 on the fuel side. Based on my cacluations with ~50-55psi (the car has about 10 psi in the intake at redline) I can use .020 on the N2O side. Keeping in mind that the relationship between jet oraface diameter and flow rate are not directly related, I have extrapolated from the jetting charts and figured that this set up is good for 75hp. I have been in conference with the N.O.S. guys about this as well, I have heard numbers ranging from 75 to 100 (I got two votes for 75 and one for 100).

My afr is in the mid to high 11's while spraying and I can't back off the shot unless I find smaller jets (I sold the progressive controller once I got around to learning how it worked, that thing is bad news IMO). So if it happens to be in the range of 125, I guess that will have to be OK

Sorry about the run-on sentences.
