100 Shot Dry (ZEX) What Do You Think? - Honda Prelude Forum

wutangben · 08-05-2003, 12:47 PM

Someone is telling me that NOS jets and ZEX jets are interchangable, if so what would be the equivilant to a 100 shot? Anyone think i could possibly safe dunning a 100 shot on my dry zex system for a run or two? I've got an ignition to retard my timing, but i don't have any fuel system upgrades aside from a VAFC. What do you guys think? Could I pull it off for a race, or possibly a track night? Just want some input, I have a guy in a stock auto C5 vette that wants to race for a grand...

How's your fuel pump? I wouldn't do it, but it's up to you. You could get a new longblock with the $1k.

I don't know if I would try to pull that off.... Even with a 100 shot (probably the equivelant of an NX 75 shot) you would be putting around 260 horse at the wheels. The C5 has 345 horse at the crank, so probably close to 300 at the rear wheels. Tough call, but I would put my money on the vette.

wow... i would say very risky for a dry kit, more so then a wet one. I dont think I would do it either, only one thing needs to go wrong and thats the end of that.

If you go for it film it please!

CTPRELUDE · 08-05-2003, 02:44 PM

I dont know about the jets, but I wouldnt do it if I were you. I think going over 75 shot with a dry kit is way to risky. You might be able to get away with it though for a run or two.

wutangben · 08-05-2003, 03:33 PM

whats with all you guys thinking that NX kits are stronger? they aren't!

as for racing the vette: before i rebuilt my trans, got my ACT clutch, v-afc, and ignition, i ran a 13.6 on my horribly slipping clutch. i know i can pull lower times now. stock C5's do mid 13's and i can only imagine the autos are slower.

so you guys don't think i should try it because of my fuel system?

i've put 25 bottles through my lude on a 75 shot and i have perfect compression... how much harm can an extra 25 ponies do?

alphajesse · 08-05-2003, 04:49 PM

Actually, man, with super torquey v8s like vettes have, autos tend to be faster, in addition to being more consistent.
With your VAFC, changing the settings to max fuel enrichment might be a good saftey measure.

Personally, I think you are getting set up for a loss here. GM tends to underestimate the power of the LS1-powered cars. It's more likely that it's pushing 345 to the wheels... Don't race him unless you can afford to lose $1000.

Good luck, though.

Toretto · 08-05-2003, 05:05 PM

I say go for it. Like previously stated, its similar to running a 75shot from a NX kit. If you tapped into the intake, closer to the filter than the throttle body, distribution of nitrous should be ok. It sounds like your Lude has the guts to beat the C5 though. If you have slicks, this would be a no brainer, the main problem with a 100 shot will be traction. He's Auto though, which means he might be a little slower, but more consistant. You can only afford to win if you can afford to lose, can you?

I know they aren't stronger, but their shot sizes are rated at the wheels. So a 75 shot of NX (actually most of the time it is 80 to 85 whp) would be comparable to a 100 shot of NOS/ZEX/Venom etc..... due to the power loss through the drivetrain. I don't know if I would run more than a 60-75 shot on a dry kit though, but if you want to risk it than why not. Sounds like your car runs pretty good though, a 13.6 is nothing to sneeze at. Also, atleast he is running the LS1 motor (which respond well to mods and run strong) and not the LS6 motor. 1G is a lot of money to drop on a race though, I think it would be close since you can pull a mid 13 right now.

MugenPoweredLude · 08-05-2003, 08:02 PM

i think youre about to lose $1G....one of my college buddies has a C5 vette auto and its fast...its really torquey off the line.....if he gets good RT and not that much wheel spin you lost.....

you on the other hand...how are you going to get that power to the ground...more than likely you'll have one hell of a time, then if you miss a shift or whatever you loose.cant forget track condtions, weather(how hot or warm)....theres too many factors.
you can pull of great times now but when $$$ is on the line, the only thing in your head is $$$....which can lead to a mistake....im not trying to flame or anything...just dont want a fellow luder to get in over his head
if you can afford to lose $$$ then go for it

now if you had a sequential tranny, i would say definitely go for it

Running 100shot on a stock engine? Good call. You're going to lean WAY out. Zex kits aren't designed to run that high. After you give that C5 the $1000 you're going to lose to him when half way down the track you put a piston through the hood of your car, you can relish in the fact that you're going to spend another $2500 on your engine.

NXLude · 08-05-2003, 10:46 PM

I wouldnt run 100 unless it was DP, but thats me.....definately not on a dry kit, your injectors wont push enough to run it safely....

jnkoh · 08-07-2003, 01:38 PM

I think the motor can take it, the problem is the distribution. However, my mechanic did run a 125 dry shot on his prelude without problems on a stock iginition, but I believe he adjust the fuel pressure higher. I say go for it!

calilude98 · 08-08-2003, 12:52 PM

Exactly. If you got a lot of the n2o in one cylinder.... BOOM. Dry kits aren't made for high shots. If you plan on running greater than a 75, get a dp kit.

red98lude · 08-08-2003, 03:02 PM

I wouldn't run a 100 shot on a dry kit. I think you lose even with the 100 shot unless you get lucky and pull a great run.

slp mode · 08-25-2003, 11:53 PM

So are some of you guys saying that you wouldn't run greater than a 75 fogger shot to the wheels or the crank. Because I have a NoS fogger, it's a 70 shot ,and I'm only getting 42 to the ground and I am looking right now to getting the whole 70 to the ground. I can bearly feel this shot, and it's not yielding good track times either, but neither is my driving.

eu4ik · 08-26-2003, 12:48 AM

i dont understand why anyone would do a dry shot, of any sort. i think its suicide.

slp mode · 08-26-2003, 08:29 AM

I've been told that it's the safest way to go with a small shot.

NXLude · 08-26-2003, 09:24 PM

wet and dry are about the same at a lower shot....a 75 is getting to the point where you shout go wet.....you should go DP, but wet is better than dry......I wouldnt do a 100 dry shot.......but you can get dangerous with it if you got it in you......
