Got a hell of a deal on a New Harris speed works dry kit complete. system is brand new. In the end I will be running a plate kit. will I be "redoing" alot of the work when I transfer over? I figure lines, power, switches, and all the saftey features will be the same? Would I just be redoing the jets and possibly noids? since I have the kit here I am eager to just slap it on for awhile. HAHA. I am not worried about a whole in my coupler I want a CF one anyways. HAHA

You probablywill just add the fuel solenoid and line when you add the plate. The jets will come with the plate. Really need to invest in a window switch for a wet kit, dry kit an automatic car can be run w/out one, but it's tough on the tranny. There is a good tps/window switch out for around $125, very easy to use. I hurt my motor on a small dry kit, so it's not just a plug and play. You should check your a/f with a wideband or make dure that the maf is reading the spray via efilive or something.

First off it looks like a few things may need to be addressed since your mods were not listed. Depending on the size of the Dry shot, unless it's very small upgraded injectors are usually required. In addition to that a fuel pump is recommended. And I wasn't exactly sure what location you were referring to in your post about placing the nozzle, but from what I gather you mean the bellow between the MAF and TB. This from what I understand would be a critical mistake placing a dry shot AFTER the MAF will not allow the nitrous shot to register therby not prompting more fuel from you injectors and will likely cause detonation. You can download the HSW instructions from the site and it gives you a good idea of where to place your nozzle in you air lid. Most sponsors here seem to recommend anywhere from 4-8 inches BEFORE the MAF and relative to the the angle at which you mount the nozzle.
I'm in nearly the same boat as you are and picked up a HSW Dry kit real cheap along with an 860 bottle heater. I have nothing but time on my hands, but am thousands of miles away from my car so I don't have the option to install it. I am still debating whether to upgrade to a plate system in the future. I picked up some cheap 39lb 03' Cobra injectors off an SVT forum for $100 with low miles. They require an electrical adapter that can be fabricated or bought from a sponsor here, but physically drop right in. It was probably time for injectors anyways, so I picked some up in case I felt like doing a Dry shot. I plan on getting a pump in the near future as well. Best of luck to you with your setup, keep us posted.

Good points on the fuel injectors and pump. A pump is almost a requirement for a wet kit as well. I made the mistake of thinking you could just install a dry kit per the instructions and be safe. This was after years of running nitrous through my wet kit on a mustang. I was using the tried and true halo spray bar, but my maf wasn't always picking up the spray. One time it got lean and I lost #7, live and learn. I know wet kits and how to tune them, so no more dry for me.

Thanks for the info guys. I already have a window switch, purge kit, nitrous filter, blow down tube, and a FPSS. I do have a EFI Live tune and everything will be monitored. I have a 2K Corvette and thought the fuel pump and injectors would be fine on a 100 shot? I don't plan on spraying more then 75 dry at the car though.

ive been spraying 75 dry and have had no problems.

Since you have efilive you can watch the maf and make sure it's seeing the spray which is critical. Start with a 75 shot and monitor maf frq., injdc, and timing. I think the vettes used the same size injectors as the f-body's, I think the fuel pump is better, not posistve on all that. With dry, every set-up reacts differently, you will probably have to tweak it a bit. I wouldn't be surprised if you needed injectors for the 100 shot.

Nope Beer not touching the 2 stage shit. I want to drive this car for a year or so. I personally don't have EFI Live but the guy who tuned my car does. I know he would be willing to retune as needed so that might be the trick.
