Umm...I'm not sure why you're running the ignition amp. I bought an HKS Twin Power (NOT PACK!!!) specifically because w/ my mods and tune, I was getting breakup at high rpm, and an ignition amp was recommended by friends, on the forum, and tuners I talked to.

LOL...man. Ppl on this forum don't let ANYTHING go unnoticed, do they?!

 

He has a Pettit unlimited ECU... no tuning required.

 

thats the point that rotorbrain should read .. lol

 

I don't believe that a "special" tune is required to run no trailings. I've had this "device" on my car for quite a while and run an ALMOST stock mod map on my PFC. I do think, however, more power could be made with fine tuning. As for gas mileage, I get 16 mpg and make about 320 rwhp

My original post on page 3 explains it and its the HKS Twin Power

 

Whoops...my bad. I thought I read that you were getting breakup throughout the rpm range, which I'd think is a tuning problem, not the need for ignition amplification.

Oh and the "Twin PACK" part wasn't directed to you. It's directed to the 1001 ppl who still refer to the HKS Twin AMP as the "twin PACK" LOL.

 

I don't believe having too much power is the problem, if an FD is tuned properly or at least close to it. The abuse of that power, or modding it incorrectly is usually what results in a blown motor or reduction in longetivity. I could see a 350 hp rotary lasting as long as 255hp rotary as long as you aren't pressing the engine for that power all the time.

I think its great that people push the envelope because it benefits us all, when new things are found about our motor, I still think there is a lot to be discovered.

 

I tend to agree.
The thing that is absolutely necessary when you start making power, and/or looking to use it is to have twin oil coolers, or at least get an oil temp guage.
Also, with the anti det, the more tourque you make adds up to more heat, which makes the need for oil temp control even more important.

 

Maybe the problem wasn't detonation, but rather what is discussed in the following link?

http://www.mazdatrix.com/faq/boost.htm

 

Nope, that's detonation anyway you want to cut it. That engine was running 3 mm seals so it's not like it wasn't built for boost.

 

That engine was not running 3mm seals. But the driver did keep his foot in it longer than he should have on a hot day at the track.

-Max

 

What do the seals have to do with a collapsing rotor face?

 

That looks like a result of the oil temps getting too hot. I wonder if that car had dual oil coolers on it?

 

Intrigueing question. I actually was thinking the same. It doesn't even have to be a hot day for that to happen.
I am dealing with what you guys are talking about right now. I have a single cooler, and my car now has a strange idle, and is on it's last days. It's not blown, still pulls good vacuum(seals are still decent) , but i'm pretty sure I have a slightly warped rotor.
It happened when I went out with the local Lotus/Ferrari club.

 

I know the ones pictures on the Mazdatrix site aren't 3 mm. I was referring to the ones pictured in the beginning of this thread. Word has it that a forum member's rotors are pictured on the Mazdatrix site.

You're kidding me right? Please don't buy into the crap that KDR feed you. I saw your rotor first hand on the first motor that blew with the anti detonation device and the face of that rotor put Max's rotor to shame. I've never seen a rotors face dented like that. It came from detonation any which way you want to say it.

How did KDR explain your second blown motor, since you now have dual oil coolers?
Was it another bad injector? Bad tank of gas? Full moon?

 

Couldn't that dent be the start of the rotor actually collapsing from heat?

 

I probably have.

Yep.

The more I hear about KDR these days...

 

Actually I dont have dual oil coolers.

Why is it that you are so against KDR? Have they ever done you wrong?

****, i understand that you dont agree with the anti det device, and yes I have my doubts about how effective it is too (im not completely naive). Its not like i have that much of a choice in place to go. The next closest rotary specialist is rx7 store which is 8 hours from me. Dave truly is an amazing mechanic, and his shop does top notch work. He may be no Steve Kan when it comes to tuning, but he still is more experienced then me. The reality of the whole thing is, I was able to run 20 psi on pump gas and not have any problems. There is another guy that is currently running 24 psi on pump gas with the device and a microtech, that has been doing so for a few thousand miles now. When my motor blew the first time, i was only running 13 psi and it was after a half an hour of breaking in my Kaaz differential in 90 degree weather. Right after that session, I went right on the highway and like an idiot decided to race a M3 that was edging me on. Heat broke my motor, and along with heat yes, comes pre ignition. Its not the end all stop to detonation. I take full responsibility for that mistake, it was pretty stupid of me. The second motor blew after taking the car out on a cold winter (Christmas) day, again this time at only 15 psi and through only one gear (3rd). He found a quart and a half of water in my gas tank. He replaced this motor for me for nothing, and I thought that was a stand up thing to do. No other mechanic would have done this! He has my business and he is gonna keep my business.

Almost every one of KDRs customers are getting the anti det device done to there car and they havent been getting any complaints. Some people even praise how much better there car is running now. The problem everybody has, is they are expecting this device to be the end all problem fix for the rotary engine, and its not. Once you remedy one weak link of the motor, you start finding problems in the next weakest link of the motor.

 

And sugar pills can cure cancer if you believe that they're medicine...

 

You know what, if someone wants to believe that their problems are solved, with something as simple as sugar pills, hey let em. Its not hurting you is it?

It may be in their heads, but hell, thats all that really matters.

 

Fastcarfreak- give it up. You have your personal experience, but what do you know? Other people know better....because they do.

 

well yes, that would be all that matters IF them thinking its fine it thier heads ended the symptom of blown engines....like sugar pills does

If this wasnt supposed to be the cure all then he shouldnt name it the "anti detonation device". The engine can still detonate for various reasons. He should name it the "cut your detonation chances down about 25% device".

 

Think of it as a free public service.

Not if everyone starts running out to buy sugar pills when they're not even sick, just because they've heard how well they work...

 

Are you saying Roger Mandeville doesn't know any better?

True. But look at all the braces that have hit the market recently. Braces for your engine, braces for your transmission, braces for your differential... when all it'd take is a new pair of engine mounts or differential bushings to solve the actual problem. Why fix the actual problem when you can take the latest sugar pill and just forget about it?

Maybe it was a case of wishful thinking.

 

If this is true, then why do we have stuff like ANTI-virus software, and why do they make updates for their anti-virus software. Because nothing is full proof, you can only keep trying to improve on the design to better the design. If every anti virus software out there, did just that, then we wouldnt have any problems with our computers and would have no use for updates. The reality is, there are ways around anti-virus programs, just like there are other ways detonation is formed.

Its not like this device is breaking motors, ****, the motors break on their own. How many motors have you been through with your car, and how long have you had it?

I had just talked to a guy at rotary revolution, who has already been through 5 motors in his car since ownership. Thats a whole lot of motors. He now has water injection on his car (a said great detonation deterant) If you think thats the end of him breaking motors, then you are out of your mind. It may aid him with this problem a bit, and cut down on the motors that break, but its not gonna stop them from breaking. Maybe thats what this anti detonation device is doing. slowing the rate at which these motors break.

Also in response to your "cut your detonation chance by 25%", Even if this is indeed all that it does. Dont you think it is still well worth it. I for one would like my motor lasting say 25% longer. If the average motor rebuild costs anywhere from 2400-6000 dollars, 25 percent of that is 600-1500 dollars. This can be far more costy then the anti detonation device.

People need to stop hating!! lol
