Hey guys. I've been using the zex 55 shot for almost a year now and was wondering if there have been any recent break throughs in upping the jets!?? I only see one person on here running a 75 shot after 4 engines and 3 mani's... sooo how did he do it? I would really like to get the full potential out of this kit! Any feedback will be greatly appreciated. Thanks

You can install a GReddy Ultimate, Interceptor-X, or some other piggyback and get to the next level if you like. The engine will certainly handle it. The only reason I have yet to do it, myself, is because I wish to develop a simple "plug-and-play" device that will help us to all get to as high as a 125-150 shot without having to buy an entire EMS just to control the ignition curve while the shot is being used.

Easy also has a few reservations about hitting a certain point where the intake manifold will not allow the fuel/nitrous mixture to distribute properly but I am not as concerned about it as he is. I have had a dual-nozzle/direct-port set up on my engine at one time, though.

Direct port eh? What are the costs for a setup like urs? And what are the drawbacks of using interceptor-x? I'm have been waiting to get to the next level for over a year....

I don't know the most recent prices for all the parts but you'd hafta drill your upper intake manifold like I did as I am not much interested in CNC'ing a set of spacers to do this. Too few people are seriuously interested in it to make it worth the time/money to build them.

The only draw-back that I know of with the Interceptor-X would be the cost unless you can find one used. If not, the GReddy Ultimate may be a better choice. Even better still is the GReddy Blue, if it has an input channel available for triggering alternate maps, as those are really inexpensive.

How are you coming along on this "plug-and-play" device? Would the Int-X let me use higher jettings or just properly tune it? Because my 8 has been tuned by pettit but not for Nitrous. I told them I had Nitrous but they said they would only tune for regular driving conditions, improving mpg and some hp gains as well as better throttle response

Doesn't the emanage get its maps changed by the factory ecu? or does that not really happen with a nitrous setup?

We had a guy who wanted to work with us but that seemed to fade away. We now have another guy who is confident on the concept being viable and his ability to design the circuits we need but it is a matter of having the time/money to focus on it. BHR hasn't the start-up capital to have more than 1-2 projects in development although our growth is helping to speed things up and finish each new product more quickly.
I don't blame Pettit for only tuning for conditions with which they are familiar, lotta liabilities otherwise and they are far more familiar with F/I than nitrous.

The E-Manage is a "piggyback" device that intercepts the PCM signal and sends the "tweaked" signals to the fuel injectors and ignition coils. I just can't remember, off-hand, if the Blue has an external trigger channel that can switch to an alternate ignition map, for example, that can be set to activate when the nitrous is spraying. I am pretty sure that the Blue cannot control a set of nitrous solenoids but the Ultimate may be able to.

In any event, MazdaManiac knows FAR more than I do about the actual functions available and he and I intend on getting around to working together on the nitrous stuff at some point.

hmm true on Pettit's part. I hope you can start on this new product soon for I'm sure it will be VERY popular among the nitrous users and persuade more 8 owners to purchase your Zex kit. I promise I will be one of your first buyers, once tested of course, and will recommend BHR to many more future clients. So please keep me posted

Typically, it takes 10-20 units before a company will even THINK about offering a product for a particular purpose. Since we are small and have other dynamics working in our favor we can make as few as 5 units worthwhile to pursue.

As for my PERSONAL passions, I would like to see the BHR Ignition System Controller get developed but with 33+ pre-orders for the BHR Midpipe I kinda need to focus on getting those done and shipped. Not to mention the never-ending demand for the BHR Ignition System.

I wonder how many people using nitrous would want to see a simple plug-and-play, easily programmable, module that makes 125-150 shots a cinch? I know I made 50 BHR Throttle Body Spacers for use with nitrous or alky last year and I am down to 15 left.

I do have some ideas that are different from Ray at this time. And my next thing is to go with a 100 shot. Let me finish the other products that are on the table and then I will get this rolling along a little faster. I hope. And the engine loss's not related to Nitrous. But the Manifolds are.

lol is that a joke? I'll give you a hint, now this is just an estimate but ALL nitrous users will eat it up! Everyone one, at this point, who is using nitrous is just itching to put the 75hp jets in. I know I've almost done it.

I'm sure the only reason your spacer hasn't sold out is because so many of use have already drilled our intakes, as I have, and don't know how to plug it up.

Anyway, I do understand your dilemma. Thanks for taking the time to fill me in.

Easy, you seem to be submitting your 8 to all kinds of harsh tests. I thank you for your research! and sorry that it has such an expense. However, it is exciting to hear that you have broken even the 55 shot barrier that so many of us are stuck at. I'm sure there is plenty of money to be made in how you've accomplished this.

If it was what we discussed the other day, it isn't that our ideas differ (since I had the same idea long before I moved to AZ), it is that after everything was considered it wasn't a viable idea. Remember, I had a dual-nozzle, direct-port, set up for a long time and the current BHR Spacer performs in the same fashion. The issue we disagree on is if puddling in the intake is a concern. You assume it is and I haven't seen the proof. You also assume the rear rotor gets more of the nitrous/fuel charge while we haen't the tangible data to prove the point. BHR doesn't have the capital right now to spend investing in a hunch.

Easy, is your 75 shot setup a sure thing or is it still being tested for faults? If it's a done deal are you going public with it? It will satisfy my urges for speed until BHR comes out with this device.

My buddy just turbo'ed his 8 yesterday and I must say... it is night and day. I haven't raced him yet but will be hard pressed to even see 2 lengths behind him. It's the greddy with no tunning. I am very jealous at the moment :(

These are things related to the 4 port UIM. Not the 6 port. :cussing: lol

Ray, ya know this is my second RX8 and I had my fun with nitrous on my first..

But if you make that BHR controller a reality, I will do nitrous all over again. :)

That said, I personally had no issues with the 65-hp jets on my previous nitrous setup (check sig). I did however have an incident while I was using it.. but I have since surmissed that was a hardware problem with the nitrous FMU and not the 65-hp jettings.

Some people have done the 65 shot and had no issues. So if you want to give that a try,, well. It's up to you. Just let me say I am not telling anyone to do this. You are on your own experimenting with Nitrous.

You mean this direct comment above? How many 4-port A/Ts will we sell that idea to? 3-4 if we are lucky. They would be better off drilling their manifold, as I did, than to spend the money on what we are discussing.

I've considered uninstalling my setup... while it is fun at the 55 shot, I'm just not sure if it's worth it. I rarely feel like filling the tank, even though it lasts for a while. I'm pretty sure a 100 shot might change my mind on that though. 150 just sounds like a blast. When I first got the system I was hoping to go higher. I have been tempted to give the 65 a try but I dont want to get myself into more trouble than I should.

We need someone like jay leno to invest in BHR projects lol

Charles R. Hill
11-24-2009, 11:02 AM
I did that exact thing a couple years ago and saw no difference. That is why I designed the spacer that we now offer. To take on such a task for the sole aspect of vanity with two nozzles wasn't something I wanted to sell to people. Too much money for zero performance gains from the nitrous system.

Besides, that EBay pic isn't the part(s) needed for such an endeavor.

Might as well get the stealth nozzle then for a super clean look.

The BHR team installed my nitrous kit this past September prior to going to Sevenstock. In my opinion the spacer and the stealth nozzle together sealed the deal on the look of the entire kit. I told Ray one of my goals was to have a mostly hidden kit for some of that mystery factor.

Without getting too far off topic, the ZEX blackout combined with the spacer and stealth nozzle gave me the look I was going for. It worked so well that at Sevenstock I had to point out to a vast amount of people that my car had nitrous. Others would see the tank in the trunk and wander back to the engine totally confused.

Even if you're not going for a hidden look the setup is very clean, completly reversable and it works great. I've had the spacer on and off the car a few times for jetting changes without any issues.

11-25-2009, 05:54 PM
Yes he did.
At that moment in time it was the 65 shot sooooo I'm over stepping his tune (bad me).

I don't know exactly all the magic accept that he retarded the timing a few degrees and the map is richer than a typical ideal fuel map for an NA tune.

Still I'm always careful, listening intently and only engaging the spray over 4.5k rpm not mention a strict fuel diet of Sunoco 94 Octane

What sounds are you exactly listening for? Detention right? And what does it sound like? I just starting running the 65shot with no tunning and I don't hear anything out of the odernary that's why I ask.

I've not encountered that issue yet. (KNOCK ON WOOD!)

Easy_E1 could likely explain why he has had it happen but for myself I'm chalking it up to only engaging the nitrous over 4.5k rpm and allowing for a little bit of over run after shutting the nitrous down.

ie) I don't flog the shit out of it up to 9k rpm and instantly take my foot off the peddle. I try to depending on the situation to either keep the revs up in neutral or let the rpms come back down slowly in gear while still apply some fuel.

Easy_E1 spoke to me about this method or at least that's what I got out of our conversation anyways.

Easy_E! you're not still blowing manifolds are you?

11-27-2009, 02:15 PM
I've read that a tuned map on the AP should b applied b4 a nitrous install what are your thoughts on this guys and what would MM tune for a nitrous setup!

Flashwing
11-27-2009, 03:21 PM
A wet shot nitrous system due NOT require tuning of any kind. As long as the car has a properly running tune then the nitrous system will work fine.

As long as you use correct jetting sizes there's no reason to apply a tune at any point with a nitrous system. If you "tune" for a nitrous shot you'll spend 99.9% of your driving time with a substandard tune for that .1% of the time you're using your nitrous. Have the car tuned properly for your non-spray driving and use the jetting sizes to ensure you maintain proper air/fuel.

Mr.We$t
11-27-2009, 04:09 PM
Ok I think I understand the car will be tuned with the regular mods Ie: intake headers midepipe exhaust, and this tune will have no affect on the zex setup correct? It will just be a finely tuned car with nitrous as an addition?

Charles R. Hill
11-28-2009, 09:15 PM

A/T models have something called a "TCM" that kinda gets in between the engine and the PCM and THAT has been the cause of Easy's blown manifolds. M/Ts have no such concern.

Correct. Because in a "wet" nitrous application, the jettings will determine the precise extra amount of fuel needed for the amount of nitrous being injected.
All the math and tuning for when you are spraying has already been done for you, just use the correct jettings.

How about you get the system on your engine, install the .017/.032 jetting combo, and trust ME when I tell you that this is as safe as you can run (especially on an A/T model) until we design and sell our stand-alone ignition controller module? :)

An alternative is to get a GReddy Ultimate, learn to "tune" for nitrous, and be a leader in that regard yourself. If you have have the willingness to swap engines every time you make a mistake, that is.........:dunno: MazdaManiac is just such a pioneer in the turbo realm and he has sacrificed a few engines in the process.

Easy and Flashwing like to chat about their nitrous kits but you can ask around about who it was that pioneered nitrous use on the RX-8 and who it is that Zex turns to with questions about it......... Maybe also ask Easy and Flashwing who they, themselves, trusted with the whole concept. ;)
