Default dry kit for corvette?

I am about to get a simple dry kit to throw on the vette for the time being. Just wondering what you guys have done about fuel? I know the injectors are fine, but what is the size of the stock pump and is it recommended to retard any timing or get a fuel pressure reg.? I am only going to be spraying a 100 shot. Any info will help. Thanks

I was researching this a couple years ago,decided not to,but,every company said a dry sysytem is a no-no on OBD2 cars.Wet systems are compairable in price anyway.Might as well do it right.
Also had a dry sysytem on my buds c4,we never got it quit right,the fuel always lagged behind,even though the pump was rated to handle,so he got rid of it before grenading the motor.Went heads and cam instead.Just my 2 cents bro,..

90% of the c5/Z06 vettes in this area run dry hits. It works very, very well. You will be very hard pressed to find anyone who has hur there motor running a dry kit, that can not be said about wet. I have over 150 passes running dry from small to very big and no issue one. Look at time in sig with a 125rwhp dry hit. I made 480rwhp and 5xx torque on stock injectors and fuel pump. the stock Walbro fuel pump is good for 550hp. Most companys try to push the wet kit because of a better profit margin. dry is safer by design and cheaper and easier to install. We offer some really nice dry kits, and just added the PRO Dry kit for the vettes. Let me know if I can help some way. We also have base dry kits for $399. I am dry guy myself. My buddy put a 100 kit on his car and base lined 12.6 and then knocked off a 11.48 on stock injectors, tune, plugs, fuel pump, a dry hit of course.

I have installed many dry kit on LS1/6 Corvettes. the dry kits work so good that most ZO6's will go in to the 10's on just a 52 jet and a good set of tires (that is 100 RWHP) or (125 hp at the crank) this VERY safe...

Very true, my time in sig I hit rev limiter into 4th (.100), so it should have been a 10.xx run.
check out my web site in sig for many vette dry pics, and in the links section for mucho info on vettes/n2o.

There are better kits than Compucar out there. I would be skeptical about using them for your C5. IMO, I would call Robert to get his suggestions and or use either use a NOS brand 5177. I have 2 stages of dry and one wet and contrary to what has been said about NOS brand, its worth the money! My .02.

Here is a link to the intro on the new PRO Dry kit, an in house Nitrous Direct kit. Based on the popular 5177 but upgraded noids (400hp pro) and SS nozzles and more. Speced for the lsx platform and in particuler the Y-Body. If i can answer any questions or help in any way, give me a pm.

I have some buddys that put a #60 jet dry shot in a rental 05 Impala air box down at a race in Bradenton this month. They have a "rental car kit" all made up ready to use at their shop. They had the 80lb fill station tank in the trunk...From what they said that car was a bear with the dry kit. Suprisingly quick. They put on the e brake and sprayed it out the hole just for fun! Four wheels smokin down the road. The fun ended on the way to Outback when the -4 line fitting broke because of the tank rolling around, filling the entire car with dense N20 fog!! Anyhow, my point is, even with this kind of dry abuse all weekend, the car ran just fine when they were done. They said on a v6 mustang rental they picked up 1.6 seconds in the 1/4! I say...Dry spray is OK!

lol, That is pretty funny. Have you seen the vid of the rental c-5 that they hid a nitrous kit on and went streetracing with it? I have used dry kits on mustangs before, just wasn't sure about the vette.

Then you just use a window switch, and set nitrous to turn off right before the shift. Then once the shift is done the nitrous comes back on. Saves the tranny.

Wet wet wet! watch your AFRs on the dyno w/ the dry kit... all over the place. not what im lookin for on a stock motor w/ stock fuel pump. at least with the wet kit you determine the amount of fuel delivery.I get a dead steady 12.5:1 AF ratio w/ 125 shot (55/36 jetting) w/ stock injectors and fuel pump.makes 560 rwtq as well.

bottom line-- even a 100 shot is going to make over 500 ft lbs at the wheels w/ A4. The stock tranny will not handle that for too long.The window switch is a good idea, but it ends costing a couple tenths, maybe more since your not spraying out of the hole. The new edelbrock progressive nitrous controller is a great way to go. id suggest if u havent already done so, upgrade your tranny servo and get a kevlar band. Up th e line pressure a b it as well. TR6s also.035.

A window switch works in a positive manner for either an A4 or M6.

i had a progressive controller on my trans am and it was great at the track, but on the street from a roll when the car could take all of the power, it kinda sucked.

if i take the trans out, i will probably get it fully built so i can hit it with a shot.

I used to have some very gruesome pics of a wet backfire in the LS1/6 intake.[I'd post em if I still had them] If I ever have the need it will be dry for me, and most likely stealth.

Your wheels will hurt you more than anything in my opinion. We only have an 1/8 mile track here, but my buddy lost a full second going from stock wheels to 20's.

As for the spray, my A4 with heads/cam, exhaust, and a 150 wet shot ran a 6.87 @ 103 with a 1.68 60' (equates to an upper 10 sec run in the 1/4). The tranny gave out much earlier. Even before I had DR's on the back. The built tranny and t/c made a world of difference (about .6 sec in the 1/8)

I'm currently looking for a system for my Z06, but have yet to decide on wet or dry. I'm trying to weigh all my options. I called Nitrous Direct yesterday for some further advice.
