how does the renisis handle nitrous oxcide?
ive seen a couple bottles mounted on cars sooo i know its been done.

Kain

that's a good question

I too am interested in nitrous for the 8. Also how much does say a 50 shot cost, including labor?

JSE RX-8

well i called nitrous express just now and got great news. the link below is capable for a 30 to a possible 150 shot of nitrous. the part nnumber is 20923-10. don't mind the talk about v6 and v8 motors. this is the kit that will work on the RX-8.

NOS jets are all priced the same UK £12 for a set, 25's, 50's, 75's etc. all the same price. It's only your NOS consumption which will drastically alter 25's 1lb nos / min 100's 4 lb nos / min. I spent almost £3.5K last year on NOS alone. Very expensive hobby. A good site http://www.noswizard.com/carnitrous.php

Trev and Ant got me going extra 100 bhp (and proven)

Will go now.

PS. WON NOS systems wipe the floor with NX, I'm sorry but they do !

For anyone interested in NOS, My old car 275 bhp with 100 shot of NOS.

Ok guys be honest. I don't know the 1st thing about nitrous and I have some questions.

1. How much and how long is an install for a basic system?

2. How safe is it really?

3. How often can I use it? Will I get addictied to the power thereby using it all the time and if I used it alot, will it damage my car.

4. Finally the install, are there a lot of wires that can be seen. When I take it to the dealer would they see the nitrous and say we're not touchin this engine?

Krayzie8

this should be sticky'd but we need some real advice about it.

JSE RX-8

-the listing i posted is 775 US currency.

-the installation price varies upon who installs it

-if you go to the nitrous express website, there are FAQ's about safety and the use of nitrous

-if installed correctly, the nitrous kit will not hurt the engine, but dont spray all the time

-the dealer should be okay with it because nothing was changed from the stock engine set-up, only things were added. but i would check on that

Nitrous is no different than any other power adders such as forced induction in that tuning is the key. If it isnt' tuned good, it isn't going to perform good and it isn't going to last long. The scary thing is that more people try nitrous than other poweradders yet less people know how to properly run it than forced induction. See a problem with this and why there are so many nitrous horror stories?

Nitrous is cheaper in the short term. It isn't in the long term though. Sure it looks appealing in that it only costs a few hundred dollars. Even expensive systems are only a little over a thousand dollars. My friend has a Venom kit on his Camaro. He uses the bottle enough that he refills it once a week for about $30 a pop. That's about $120 a month or over $1500 a year in refills! He's had it for over 2 years now and paid $1200 initially for the system. $4200 is cheap over 2 years? If he had spent $4200 on a turbo or supercharger kit and kept it more than 2 years, he'd had come out ahead. He also wouldn't have to keep unbolting a bottle every week. On top of that when the bottle is empty, he doesn't have the gain that he wants. Forced induction is always there. It doesn't run out. It isn't any less of more dangerous than nitrous either. Tuning is critical.

Nitrous can be a good thing. If you use it on limited occasions and dont' refill often and only intend to keep the car for a couple of years, it may be cost effective. The only bad aspect of it is the installation but a couple of extra days in the shop is definitely worth the wait if the gains are permanent and there when I want them and it isn't any more expensive in the long term.

I'm not nitrous bashing, I'm only pointing out short and long term investment aspects of it.

How about forced induction, and nitrous? :D

Street engines that use both nitrous and turbo generally do so in a serial combination as opposed to a tandem operation. The nitrous system is used to create a larger exhaust pulse which causes the turbo to "spool up" quicker, therby eliminating(or at least lessening) the turbo "lag". Kinda like the 3rd Gen, 255 h.p., sequential setup.

JSE RX-8

its most likely possible if internal work is done to hold the power. rumors have been flying that the stock motor will not hold more than 300HP. if massive internal work is done when you put a turbo on, then nitrous will not be a problem

Super Street mag has a feature on the rotary engine. IMO, the piece doesn't have information that is any different than that which we share with each other here. However, it does have a load of info from some familiar people regarding the GenII and Gen III turbos. This is important due to the evolution of the rotary. Rotarygod and myself think there is much to be said, and noted, in watching the engineering evolution of the rotary. The point is, that although there is not much tech./info. available at this time for the Renesis, by noting the history and aftermarket response to previous versions we may be able to prepare ourselves for that which is to come. Note about the above mentioned part number for the NX nitrous kit; it is the same kit used on their Mazda 6 install which is posted on the website. It seems as though my concerns over the fuel rail and using the Schrader valve as a pick-up point have been answered. I am putting NX at the top of my list for nitrous systems.

JSE RX-8

yea nitrous express is on the top for me too

NOS should to be done the right way. You need to go with a wet shot & "direct Port" on the Renisis. I just ordered an extra manifold and I plan on making my own "direct port" setup.

Todd Green

RX8on19s be careful when calling nitrous NOS... there is some a**hole on here that will make fun of you for callin it that... i think his name is Ike!

charles what kit are you talking about that they fixed from the mazda 6. and what company is it .also what do you thing about a zex kit ?

Charles R. Hill

iTrader: (7)

I would love it if the Zex kit worked on the 8. Zex's website notes that the wet system with the modular solenoid box(part #82021) will only work on cars with a vacuum-controlled fuel pressure regulator. It would be a very neat and tidy install to have only a box and a few lines and wires to hook up. I would also like the install to be as stealthy as possible. The problem is, as I am told, that the RX-8 controls the fuel pressure via the ECU controlling the voltage to the fuel pump. This keeps the fuel pump from being under full load all the time, thusly leading to longer pump life. I don't see why that would be an issue, though. The only time the nitrous would be used is at full throttle which puts the fuel pump at full delivery anyway. Maybe Mazdamaniac or Snap-on can correct me if I am wrong about this. For my system I am considering a number of small, maybe 5 pound, bottles to hide in the floor of the trunk where the recess is. It should be another week or two before I get it all figured out and ordered up.

I just re-read the info on Zex's website and I was looking at info on the DRY system when it noted the fuel delivery and vacuum ported regulators. My mistake. However, i seem to have difficulty in finding info on their wet systems. I give 'em a call in the a.m.

Those people interested in Nitrous, have you checked out the electric supercharger from Thomas Knight.

15 secs of boost on a single charge of battery power. Seems to work well. I think some of the RX8club members are thinking about putting in.

Discussion on Electric Supercharger

guy321

for the guy who started this thread, there's already a couple of good threads discussing nitrous installation in our cars and part #'s etc.. so get off your lazy *** and go do a search.

Before you get a stick up your butt about me, let me explain something.

Some of us (despite not having installed a nitrous kit) , have put alot of research into installing nitrous into our cars. We've spent days , even weeks doing our own research, calling the differnt manufacturers, taking apart and looking at the various subsystems of our cars.. Then to help people out we post the info here...

Several months later, no one bothers to look at the thread and people ask the same old question and expect us to retype all our research???? I don't think so. It's out there, if we've taken the time to do the research and share it, you should take the time to look for and read it.

It would be different if this thread were started with intelligent questions.

GUY321 if you dont have anything regarding the subject of the thread why the hell answer it . did you ever thing maybe we wanted to discuss the subject again? you say quote: It would be different if this thread were started with intelligent questions. i dont think your to bright yourself in fact i think your childish . IF THE THREAD BOTHERS YOU THAT MUCH DONT READ IT ! its that simple. OH AND THAT DO A SEARCH CRAP IS GETTING REALLLLLLLLLY OLD!!!

guy321

I never said I wasn't childish. In fact, I'm being an ***. However, my post was still more constructive than yours.

Furthermore, aside from Charles and Magic8, no one has contributed any useful information.

There is more in the past threads. Some of those members who did research and posted do not post any more.

Also, why should the wheel be reinvented just because someone joins the forum later than others? There's a wealth of information out there. You think I'm being childish, what about the people who demand the information they want when they want it instead of taking the time to research it for themselves?
