Wet And Dry Kit Combined???

What do you guys think about this idea.I've seen someone do this on a corvette board.I would have a NOS dry kit setup for 50 h.p. for street use,and a 150 shot wet for the track.My thought is to use the wet and dry together at the track with 105 unleaded gas.I think shooting the 50 shot through the mass air will retard enough timing to compinsate for the total 200 shot on race fuel.What do you guys think.

I suppose you could make it work, but you're installing a lot of duplicate parts, and I'm not sure why. Why not just install a normal wet system and swap jets for the track?

basically, your talking about a two-stage set up. why not just use a 2-stage WET and keep everyting the same?

what would be the purpose for trying to combine a WET and DRY kit?

i guess MAYBE you could possibly make it work, but i personally would never do it to my car. i would think that with trying it combined like that, there might be more of a chance for somthing to go wrong?????



i really dont understand WHY you wuold want to do that.......

I do agree with the saying " keep it simple" but my reason for the dry kit is to pull timing out. Plus with the 50 hp shot dry I'll have a easier time hooking on the street and still run 11's.By using them both at the track it makes it easier to come out of the hole on drag radials with a 50 hp shot and then WAM stage 2 the 150 hp shot.

The install would be clean and not disgusting.All I need to do is put a NOS y block on my feedline and branch off into two solenoids.One solenoid will be for the 50 shot with a small and simple fan spray nozzle plumbed into the air box.While the other solenoid will be for the second stage of 150 hp. What I think is is your riced out red floor mat,steering wheel cover, interior with that cheap Sunpro tach.

Why would spraying nitrous through the MAF sensor cause the PCM to retard timing? The only thing the MAF sensor tells the PCM is the mass air flow..... as represented by a variable frequency signal. The PCM does not adjust timing based on mass air flow... it adjusts timing based on rpm, MAP and possibly a small (3deg) blip from the IAT sensor reading..... (the elusive 3deg that no one can find in the timing tables...).

that, plus, EVERYTHING ive ever heard about spraying on EFI cars, has been- make sure you put the nozzle/plate/point of induction DOWNSTREAM of the MAF. from what i read in GMHTP they concured.

for those of you that have actually seen the inside of a MAF, those ity-bity tiny sensors that look like their holding on by a thread, those are the reasons they say dont spray ANYTHING, wet OR dry, before the MAF. if one of those get knocked off or bent, or whatever, you get to go out and hunt down a used MAF or pay another 340 bucks for the new BBK you just bought.

i know on the LS1s, most of the kits are made to mount before the MAF. i have no idea why??? i would NEVER do that to mine.


FYI, GMHTP stated, and i quote "One reason nitrous works so well on late model fuel injected cars is because the computor doesnt know its there."

Ok I wont beat this subject to death.So I'll just go with a 150-200hp wet shot.I'll possibly get a progressive controller to minimize traction problems.

You aren't going to "knock off" one of the resistors.... as long as you don't have the spray nozzle (dry system) immediately in front of the sensor, everything passing the sensor will be gas phase. No different than the air is normally measures, just a little colder and a higer oxygen content. The NOS dry kit (5177) for the LS1 works fine. I have never seen anyone damage the sensor by spraying (dry).

The dry kit works well on the LS1 EXACTLY because the PCM knows its there..... .

And, GMHTP magazine is far from the technical bible on nitrous...... .

oh, and i suppose YOU are the tech. bible on n2o

most of the guys at GMHTP have considerably more automobile knowledge than me, and thats reason enough for me to at least take heed to suggestions they make. AND, like i said, thats not the only people ive heard that from


so, you can put your nozzle/plate wherever you want, and ill keep mine DOWNSTREAM of the MAF

I never claimed to be, and no one has given me that title..... Just remember, the guys at GMHTP magazine couln't even diagnose a failing Opti on TGOW, even with the help of three shops - by John Hunkins own admission. They had to come to CZ28.com for the answer...... .

It's your car, do as you wish. No one is forcing you to change your mind. Just offering factual alternative opinions so that reasonable people can make up their own minds.

He may not be the tech bible but i garuntee you couldn't touch him when it comes to car knowledge. He's helped more ppl on here then you could ever count.
