so i have been debating on doing a direct port setup on my car for awhile and i could do it the normal way and use 6 wet foggers or i had a friend come by and suggest using 6 dry nozzles and just add the extra fuel with tuning.

he said he had heard of some hondas using that setup.

any ideas on this setup on the Z? i used my spare engine on the stand and bolted the heads and lower collector on to use to mock up fogger fitment.

Why and is your car going to be strictly for drag? I take it you are shooting for 10's.

I don't know of anyone that has done a setup like that with a Z maybe Audiblemayhem or the guys from performance motorsports back in the day. I think they have a vid on YouTube.

a lot of guys have gone really fast on a single nozzle. unless you are running a really big shot its not worth it. the jet sizes are very small. imagine a 150 shot, broken into three nozzles... thats 25hp a nozzle. that said, if you are dead set on a direct port setup, look into the kinetix manifold. that would be the easiest one to plumb by far, and you could use wet nozzles with a rail. thats what i would do if it were me. i think you could also do it with a cosworth intake, several ways... there isnt a lot of room with the stock setup. how big of a shot are you really gonna run?

yea pretty much drag only. i never drive it anymore and yea i got 10.80s on my brain now and its gonna make me crazy



i have a plastic kinetix on the car now and the issue with the single wet fogger is that the fuel and nitrous dont mix and distribute evenly with my 150 shot. and i have blown up 2 kinetix from the fuel puddling up in the plenum.

and i have a spare engine on a stand i have plenty of room for the nozzles and lines with a wet or dry direct port. i will be running a 150 shot.

Do you think it's from your 25 dry shot? Maybe the ECU is dumping too much fuel to compensate for the extra nitrous.

I don't think you started blowing plenums until you started 125 wet and 25 dry.

i dont know exactly. i only had a 100 shot before. i went to the 2 stage. i may could switch to a different fogger that flows better and not have any issues.


the last time it happened i know it was fuel puddling up because the plenum blew apart and the hood blew up at the back and i could see the fuel burning and it actually scorched some stuff in the bay.

and do you still have the link to that nozzle test?

Your 2nd stage is setup before your 1st right I cant remember? Maybe when the 2nd stg hits it causes your 1st to not atomize properly anymore.

no the 1st 125 is on a wot switch. the 2nd 25 is on a button i hit in second gear.

but the problem with it is flow. i dont have the 2 solenoids hooked up with a Y they are inline and i have had the car on 2 different dynos and when i hit the second stage i lose 10-20 ft-lbs but gain 20 hp
on 125 shot i make 370/409
on 150 shot 2 stage i make 389/393

YouTube search NOS vs NX nozzle or nitrous express.

No what I mean is when your 2nd stg hits maybe it disrupts the flow of your wet shot if the dry is before the wet on your intake.

yea its before it on the tube. i see what your saying. im probably not gonna use it anymore. i may try getting some 150 shot jets and get a nice fogger before i try the direct port.
for the 125 wet im running 52n 28f right now and my 100 shot was a 46n 24f
i just think my nos fogger is maxed out and not getting a good mixture

i just bit the bullet and ordered a dynotune nozzle and jets for a 150 shot.

il try that before i do the direct port setup

You will notice a difference what jet sizes for a 150shot?

Interesting. Keep us updated.

fyi i didnt mean the plenum... i meant the velocity manifold with the 6 visible, separated runners... it would be easy to mount 6 wet nozzles on that and have easy access for jetting changes at the track. thats why i suggested it.

that said, i think the trying the 150 shot single nozzle is a good idea before you take the direct port plunge. ive read about a few people running that much on a z with good results. good luck and keep us posted!

i ordered a 58n 32f

Hope you have enough fuel and good choice on the dynotune nozzle they were at the top of the list that nozzle shootout (10+ nozzles) NOS was last.

I'll post the link later.

yea im nervous about spraying the big single 150. i was gaining 182 ft-lbs off of just a 125 shot. i think the car will be faster all around with the single 150 because i wont have the dip in tq when i spray the second stage. im hoping with the bigger shot i will be able to get my 60' times down in the 1.57 range. im probably gonna install that diff bushing i got from you, and a set of soild engine mounts i had fabricated.

here is that link for the nozzle shootout.

See what your A/F is before the track and I would get different size fuel jets to adjust if needed.

Threefivezero what size dynotune jets are you using?

here is that video don't know what shot, but it looks like a direct port.
