Nitrous time

[mikeb17]

I will be experimenting around with some dry shot (dry for simplicity) nitrous here shortly and will be starting off with a 30 shot. Car has RPM rods so I'm not too worried about breaking anything. I wil slowly bump up to a 75 shot while keeping track of all my logs to make sure I'm staying healthy. I know nitrous is some kind of forbidden voodoo to you guys but I like to party. Nitrous brings the party. Will post results after. Also any feedback from peeps who HAVE ACTUALLY USED nitrous is welcome.

SS4 ran a 65 dry (iirc) shot with 84 lb injectors, upgraded intank 044/stock fuel lines/rails on an RS6 setup for awhile.

sfored has run nitrous on some of his S4s in the past as well. Considering a well sorted stage 3 car can bend a set of rods, it doesn't make a ton of sense for most to do it. I wouldn't say it's taboo for this platform anymore, though.

[MacDaddy]

Interested in replies, from what i have read anything under a 50 dry shot is safe on almost anything, plus its so low you dont have to refill the bottle very often, may be an easy way to get a stage 2 car up to stage 3 power.

[S4tech2]

That's interesting^. Until you get the kid that sprays 24/7 and wonders why his shit blew up. Nitrous isn't a bs thing when you understand how to use it me apply it.

Just be careful, these blocks can't take an insane amount of abuse. Watch that torque if you get into the 650+wtq range. Low oil pressure and loose side main bolts are the signs of cracked mains.

Someone should win the lottery and re-engineer the block for thicker, 6 bolt mains. Maybe billet?

nobody asked so i will..
why not a wet shot?

[GrapeBandit]

im all for nitrous, preferably a wet one.

We should just have find someone who would engineer a billet 2.7 block with all the bells and whistles. If only that was reasonably attainable.

A year or so ago we had offered to design/manufacture a limited run of nitrous plates similar to the ones we make for the B6-B7 S4, but nobody wanted to pony up and buy them.

Lets go JHM we are waiting. If you design them and manufacture them, we'll try them.

The reason being for a dry shot over a wet shot is simply tuning. Our computers are MAF based and it's honestly just easier to tune for than a wet shot. It's also cheaper and easier to set up. I tune my own car and while I get the job done I'm not some wizard at tuning. I know my capabilities and what I feel comfortable with. A wet shot mixes with the fuel and you tube based off of AFRs while the MAF will auto adjust fueling based on your nitrous shot.

Specially after the last offer, we would not even begin to make them unless at least 10 sets were paid for.

..and even then I don't think that is a project we have time to take on at this point in time.

actually a wet shot is easier to tune for or not tune. it adds fuel, youncan run a wet shot with no additional tuning, cant say the same for a dry shot

[mikeb17]

You will have to tune for either way and my personal preference since I'm doing it is to just run it through the maf :) I feel safer this way. The dry shot is also cheaper and easier to set up. I thought about just tapping into my water meth bungs and doing a wet shot before the throttle body by I'm going with the dry shot. I'll post results up for you guys when I have it done. Couple weeks out.

essentially a retune will net the most gains, but it is not necessary on a wet shot.

all nitrous cars i ever saw spray post maf. have you ever shot it pre~maf before?

I'm excited to see what happens. Nitrous on an s4 sounds sweet

[Nollywood]

Like boost, nitrous can be addictive. Run too much, and the motor won't last very long.

[mikeb17]

Ive never played with a dry shot which is why I'd like to try it! I'm currently working on rebuilding a 454 for my chevelle and it will be running a double 150 wet shot.

Alot of people run dry shots pre-maf. Easiest way to get the car to add fuel.

hmm. that's news to me. what if your ecu cant compensate and add enough fuel, or what if your fuel injectors arent big enough to flow the requested fuel? all the reason for a wet system since it adds its own fuel.

wet kit just seems more fail-safe to me

[vavJETTAw36]

Nawz will turn a 10 second quarter into 45 seconds. Haven't you seen the movies?

Well I've changed my mind and will be spending a few more dollars and going wet shot. Usually you only run enough dry shot so your car can keep up with the fueling. However after more research I was reading on these disasters about MAFs getting too cold and actually freezing over with too much dry shot. Our cars literally live off of the MAF and I don't feel like blowing up my engine. Dry would of been cool and different but ill spend another 200 and go wet. I plan on tapping in right into my bipipes before he throttle body.

[MacDaddy]

I wondered about the freezing thing

I completely agree, I just know a lot of f-body guys do it. It's been a while though, that was back when they were still relatively new.

I've already scaled back my MAF to keep it from maxing out load. I don't think I would count on a dry kit with it.

[mikeb17]

New and exciting news! My father is going to be making me throttle body plate for injecting nitrous because he doesn't like my bipipe idea haha

Will he make more if we order 10 and give him a million dollars?

Sweet man! Always listen to dad, he has more sense than we do.

What threading is needed for the nitrous, could you just use this already made and available TB spacer for meth kits?

[mikeb17]

Let me go see what size thread is on the nozzles and I'll report back. That right there could be the way to go. Getslideways... You keep me on this forum haha.

Getslideways... You keep me on this forum haha.

Does that mean I am making your life better or worse? lol

Always happy to help if I can, looking forward to seeing your project develop!

[mikeb17]

Thread size is 1/16. I see it doesn't specify the threads on that throttle body though.

And you make my life better lol you're hilarious and funny

Hilarious and helpful*

[mikeb17]

I also have a 1/8 nozzle as well.

[getslideways]

most of what I am finding for meth nozzle threading seems to be 1/8" npt, I would double check by emailing that spacer plate maker to be certain, but I would guess it will be for 1/8' npt. However I wouldn't be surprised if these are made to order, so they could likely put whatever threads you needed in it.

Also, thanks for the kind words, you obviously have great taste in the company you keep lol

[hibiscusS4]

i love nos threads

[mikeb17]

I was never interested in doing it until my father gave me his old nitrous kit from his old drag Nova. He ran a 6.08 eighth mile and a 9 something in the quarter mile. I believe he ran two 150 shots. I was given free stuff so I might as well use it. I'm just waiting on my heater, purge kit, and progressive controller before I go ham.

[Mille Bornes]

Would you need to trim the TBB to make that spacer work? I was just wondering how everything else would fit together with that since it's already pretty tight at the front

I'm kinda worried that it will cause the map sensor to smash into the hood which already happens enough with my 034 boot :/
