Who sprays, what setup, what nozzles? I want to know details, I have been looking at direct port setups and just want to know who else (if anyone) is spraying.

There was a member on here a long time ago (I think he got banned so I won't mention his name), but he used to spray is stock 99 I think? I think he ran megasquirt with like a 100 shot. If I remember correctly he used to run a low 14 second 1/4.
His name ends in MX5s and it'll say "I'm miserable" under his name. Search it up!

Patrick aka patsmx5.
Friend of mine.

He got rid of it for a large turbo setup a long time ago and still enjoying that.

He said he ended up getting sick and tired of nitrous, and didn't recommend it when I talked to him about it.

I will likely be running it on my budget car to get a large turbo spooling on my budget racecar.

I ran a 100 shot DP on my 99, then later went turbo instead.

My thoughts:
1) Direct Port is a must.
2) Dry nitrous with fuel compensation from the ECU is way better than a "wet" kit.
3) Buying good parts has a big impact on how well it works, everything from the feed line, to the solenoids, to the nozzles.
4) Dont be a retard and use massive a feed line. Small nylon line will flow plenty of nitrous and wont take long to prime. You DO NOT need a purge.
5) Check out noswizard.com, there you will find the best nitrous forum on the planet, along with the best nitrous kits on the planet. Talk to Trevor and it will all be clear.

Yes you do.

I have run it on many different cars with many different configurations (dry, plate, foggers)

In the Miata I ran a 13.16@ 101mph on a stock motor with stock ECU, clutch, light flywheel, exhaust, and slicks. My nitrous system was an NOS dry kit with an additional fuel pump that ran only when the system was armed.

I currently have a Wilson Manifold fogger kit that I will be installing soon after my next motor is built and tuned. I will convert it over to a poly line for ease of installation and for easy jet changes. The foggers will be under the intake.

Here is a crappy pic of the solenoid mount I made.

Thats because your feed line is too big.

You dont need a purge with a properly sized feed line. -4AN will support several hundred hp worth of nitrous. A 4mm nylon line will suport a 100 shot and its outer diameter is smaller than a -4AN inner diameter.

On my setup, even with having just connected the bottle, there was only a momentary blip before nitrous was there in the manifold. Once it was primed after that first hit it was instantaneous, always.
With my -4 it would take ******* forever to prime without a purge.

You are missing the whole reason for running a purge. It is for releasing nitrous in order to correct your bottle pressure if you find it is too high when you are on the starting line.

Edit: Actually, I ran a smaller line than a 4AN. Nitrous line was always smaller than the typical AN sizes.

Sorry, I should've been more clear. This is a built 1.6, ported and gasket matched head/manifold that is turbo'd. Usual bottom end, wiseco pistons, main/head studs blah blah blah. ECU is a DIYPNP, I would like to run e85, but I don't know how well e85 and nitrous mix. I basically just want more power without going to a real bug turbo, if that makes sense. The ability to drive the car how it is but with the potential for some big power gains up top if I spray. My wants might be a dumb idea though, trying to learn more about it

How big of a turbo and how much boost are you running?

In that case he should learn to brake boost properly.

Its hilarious how bad most people are at it.

RyanRaduechel

iTrader: (10)

Ask Vlad how good I am at brake boosting, he will tell you.

Troy, I have the choice of a Garrett T3 .60/.63 or an eBay special T3/T4 .50/.63. The motor is still being built, so the boost levels are undecided yet, but I am shooting for ALLOFIT. lol I think the Garrett is too small.

Sell both turbos and buy one of these bad boys.

Did Soviet sell his? IIRC he had one but didn't install it, and went with the EFR instead.

If you go big with turbo and boost, you are stuck with running the nitrous only at lower rpms and boost range. Even the high budget big boys have the nitrous shut down once the boost reaches a certain level. In this case nitrous is used for spooling sooner and better launches at the drag strip. Nitrous cars still dominate the race to the first 60'.

If turbo and boost levels are tame enough, you can use nitrous all the way to redline. You can only shove so much oxygen and fuel in the combustion chamber without all hell breaking loose.

You may even consider a reverse multi stage nitrous set up. Two small stages of nitrous on the initial launch, with one shutting down at full boost.

I honestly think instead of all this wizardry you should just run mild tune on pump and ALLOFIT on e85 and skip the nitrous.

That is unless you have a spare setup and wouldn't have to invest any money at all into it. In that case I'd probably experiment with it.

Damn it! Don't talk him out of it!

So when is this going to happen? Oh, and be sure to get a set of slicks. You are going to need them.

I do have another engine, but it is a SNC, but if that craps out I wouldn't care too much.

Well I am still building the engine. I just got a 1.8 swap with a 3.90 Torsen, and its on Toyo R888's. Once I get everything sorted and running I will have to figure on the boost levels and go from there.

Then I'd have to remake my downpipe. Although that turbo is pretty damn cheap.
