Just meet me for some Quiznos on Fri the 19th when i come to get my car. Lunch is on me! Dont worry about Nah sayers. If it works they will all be begging for it too.

 

Maybe that is why they are not going full bore with releasing it. I do not know. Don't most inventions go through vigorous tests before being mass produced and released to the public?

I agree, there are other things that can toast your motor. This device was sold to me as anti-detonation. The torque increase, lower Octane gas, and running a leaner mixture are just benefits that go along with it.

You still must pay attention to air-fuels, timing, EGTs now because of heat. Before it was heat and detonation.

The tune it myself was my choice. I was told to shoot for lambdas of real low 12's under boost. I was also told that if running boost levels of 20lbs to run at least 89 Octane to help with the higher EGTs and the possibility of increased coolant temps which I have not seen yet.

I have it tuned pretty close to where it should be. I was having some problems with fluctuations in the lambdas that I did not see before. I must check with KDR on Monday and see if it is related to the mod or not.

The car screams. It never ran this good. The pull is increadible. I also noticed that the turbo spools faster than before. This may also be contributed to the heat sheild bonnet that I have on the turbo.

 

Matt I'd love to, but I am away on business the 19th and 20th.

I am sure that upper and lower polished intake will look good under your hood :>)

 

I am telling about it. My experience with it. Haven't I posted a fair amount of information?

My engine would have blown today. Due to detonation that is. 87 Octane, 12lbs of boost would usually mean kaboom. Plus tonight I cranked her up to 16lbs and gave her a couple 7 grand pulls. But hey,I am not putting my foot in my mouth. Who knows what tomarrow will bring. You gotta have high hopes my friend.

 

Damn guys is it really neccessary to bash a product that none of you have any clue about? Seriously, it makes absolutly no since. You know I constantly see stuff like this on the LS1 forum. Example: Bring up anything about the Rx7 or Rx8 and the threads turn into flame wars and eventually get locked because of their lack of knowledge of our cars. As BATMAN & zkeller have stated, the product is in it's R&D stages and patents are trying to be obtained. Lets give it some time and waite for the product to materialize and "prove" itself before we pass judgment. By then, I'm sure we will know exactly what it is and will not have to worry about "accidentally" removing it. One last thing, people thought we would never travel to the Moon. Well........ is it me or are their some big *** foot & tire prints on the surface?

 

Here's a question but I don't know if you can answer it: I thought one of the things that was stated by someone was that the "device" was put on a totally stock car and blah blah blah...Is that even possible? You've mentioned tuning a number of times, and said the device didn't like certain types of tuning that you had before, etc...if you used it, say, on a mildly modded car w/ stock ECU, or maybe a Pettit ECU to remove fuel cut...is that even a possibility?

And so they're putting a gun to Zach's head in order to force him to use the device? And there's some sort of security device that will blow the car up if he tries to look under the hood and see what it is?

Geez, come on guys....you're really starting to grasp at straws here.

 

From the "Quote" Removal or improper installation will blow engine, speech, it does sound as if batman was on the right trail (StarTubes), plus think about it who takes off the intake manifold to see what sits between the injector and your fuel rail !? I know better than to touch the rats nest... from what I've read on the KDR site, and the sense that batman made... Star Tubes Plus Plasma Ignition should do the trick. The star tubes website also stated that they had as much success as failures, due to .... probhably improper fitment, and incorrect length, from the sound of Star Tubes it sounds like lenth and vortex generated are critical in getting the "Homogenious" mixture of Air and Fuel.... Sounds to me like KDR isn't trying to patten ****, they just want to put a kit together that a competant mechanic can put on your car, and possibly cover themselves from getting sued for engines popping due to poor installation.... cause if this was a copyright thing any one of the people that have this would have had to sign an NDA, which from the posts here would have been broken 3-4 times allready... and with plenty of proof, and I don't think the people here are going to set themselves up for litigation !?

So go for patience or try and talk to your mechanic about replicating the results .....

Im not saying anything bad about you and im not calling B.S. or doubting you. Im simply saying that if anyone buys this product that is advertised to prevent detonation and actually detonates well....I need not say any thing else.

 

again this has nothing to do with Zach, please read it again.

 

zkeller, since you have this device, any idea how reliable "it" is. I mean I would hate to have this "anti-det" device malfunction while running 87 octane at 16 psi? Also, is the device safe for all rotarys(NA,Turbo,20b)?

 

wouldn't it be safer still to run 93? i always thought the higher octane fuels were cleaner burning, and were better for preventing detonation... why would you want to run 87..... what is kdr's reasoning behind this?

 

That's a damn good question that I cannot answer. You may want to consult KDR about that. Certain types of tuning should be stated as overly rich or overly lean, ie: air fuels of 10s and 11s or on the lean side 13s and 14s?

 

I have only had it on for a day and a half. Seams pretty reliable so far. I thought about the 20B as well because someday in the next year or two I would like to start planning for a 20B conversion, on another FD.

I heard some "banging" from under the hood last night that scared the hell out of me. Turns out my BOV was rubbing against the hood.

 

87 burns faster and actually burns clean as well, plus it's cheaper than 93. As someone mentioned earlier, rotaries make more torque with 87. Maybe a marketing ploy as well?

 

I've always heard that the whole concept of higher octane fuel burning more cleanly or being more purely refined is BS. However...I didn't think it affected the rate of burn either, I thought it was purely resistance to detonation. I could be wrong...

jds

 

you are contadicting yourself with that statement.

 

87 burns at a lower temp, not "faster."

I think I read somthing about a patent being applied for. Any idea how long ago they did that? Max of 6 months from the original filing to get a notice of acceptance or denial. Max of 3 months from a letter of acceptance to actually be awarded the patent.

zkeller...you mentioned that if you demanded to know what it was, etc. that you wouldn't have it on your car??! Just because they say it works doesn't mean that it does. I dynoed my car recently and they claimed I had an 18:1 AFR and was only putting down 195 RWHP, that doesn't mean it's true.

Ok, let's assume that you DON'T actually know what it is and what it does and where it's located. What you CAN do is give us a dyno sheet of before and after. KDR being as secretive as they are obviously have no intention of installing this thing on a lot of cars as people are skeptics. If I don't think a $500 piece of something is going to improve something by way of performance with some hard evidence to go along with it, then whoever is selling that is out $500.

Did you sign a NDA with them? You never got a guarantee with them? Are you their guinea pig? How exactly are you affiliated with them. Surely these are not restricted questions.

You can't some on here and say, "I've got it and it's awesome" and leave us up hanging and not tell us anything about what it is and does. It's all intangable evidence. Surely you should have known that by coming on here and giving partial descriptions that you'd invite the nay sayers and all the **** talk to say what's been said thus far.

How about we skip all the BS and get some real world answers. Is it hardware or software? Play with timing, fuel delivery, both? It is nothing more that a really good knock sensor? What the hell is it that you get for $500. These are the kinda questions that KDR themselves are going to have to answer if they expect to make any profit off of this. I don't want to hear "they can't say anything" anymore. DON'T say that you can't say anything. Just don't say ANYTHING until you supposedly can. And more more 3rd party crap. "I know them and can tell you..." "They said..." We want info from the horses mouth, not through the grapevine. And i know Batman seems to be an advocate...I don't know if he knows you, but I don't want to hear "Oh, but he know's them really well." If you work for them, fine. If you don't, I don't want to hear it until some official rep from there says it.

My $.02

 

Even the nay sayers wouldn't say it to ur face.

Ur built like a Gorilla.

Worse case they will get a free knuckle sandwich from u.

Drivethru style.

 

My guess is that if it does indeed fail and ur running 93 octane at 16psi with the A/F ratios that he is running then u better open up that check book.

 

I like to know if I can run 14.7:1 A/F ratios while cruising and not at boost.

That would mean great fuel savings over stock levels.

 

whew!

 

Negative, ghostrider. 87 octane fuel indeed burns "faster" than 91 or 93 octane fuel. And that increased "flame front" speed results in higher overall EGTs, which explains why they recommended higher octane fuel with higher boost settings.

 

This is obviously a very controversial subject. Just look at the number of views in a short period of time. Everyone wants this to be true and an unbelievable product. Maybe it will, maybe it won't.

I think you all should know that Dave has one of the busiest RX-7 shops per employee in the nation. He has always been backlogged with work. Jobs that should take two weeks many times take months due to being backed up. He recently stopped taking new business till he got caught up. I'm sure the strain of testing and getting the legal issues solved on this product are very time-consuming also. If he e-mails me that it should be ready for "retail sales" in 2-3 months then it's probably more like 4-6 months. The point is he must think he has something here and it will be available when it is fully ready for mass distribution. These are, of course, my thoughts on the issue.

If this product turns out to be another unconventional product like Aquamist water injection and Racelogic traction control that works great, then I'll be getting it.

My point to you all is, be PATIENT.

Ken

 

IMO, if this device is proven to allow me to run 87 octane with previously unusable boost levels, while providing more torque and better spool-up for $475 or whatever, I could give a **** less about what the advertising says. Sure, you can misuse any product, but if it indeed allows better performance when used correctly, then it's worth buying.
