Jesus, just run low compression Turbo II rotors and be done with it...the 93+ rotors are so thin and weak to begin with, hence the dent or deformation caused by localized heating. It got so hot that it actually warped, pushed in by the combustion forces. It is a well known problem that most engine builders refuse to address. The actual rotor thickness can vary greatly depending on where you measure it on the 93+ and looking at a third gen rotor that has been cross sectioned is truly scary. Very inconsistent and not very well made. One would be better off with the n/a high comp rotors due to their better build quality if you did not want the lower compression ratio. The older rotors are heavier so have them lightened. No need for dynamic balance, a static balance is just fine. There are several shops around the country that lighten rotors. Not as easy as a butt plug but then reliable horsepower never is.

 

i never saw KD posting anything in regards to this product. It was their customers thats hyped it up not them.

 

Customers were supposedly under a non-disclosure agreement, reportedly required by KDR's application for a patent. That rumor/fact alone was enough to hype the product without anyone else's help, and that was all KDR's doing, not the customers.

 

HEY GUYS question what would it take ? to make 550 RWHP on a 13-b 2 rotor engine, and have some reasonable integrity

 

I hope you have a big stack of fire-proof blankets, cuz you sir are about to get FLAMED. Thread hijacking, not searching, repeating one of the most common questions, using newb terminology, asking the impossible...should I go on??

 

I think I asked this before, when will someone make inconel rotors, Iknow I know, the R&D involved, they could be 1/2 the weight and glow red without deforming, just a thought. RON

 

Customers were supposedly under a non-disclosure agreement, reportedly required by KDR's application for a patent. That rumor/fact alone was enough to hype the product without anyone else's help, and that was all KDR's doing, not the customers.

If they did not require a non-disclosure, which to my knowledge they did not, how was it "all KDR's doing?" KDR may have some faults, but hype and integrity deficit are not among them. I have noticed that, for the most part, the most caustic skeptics have never dealt with KDR, and assume things that aren't true. KDR always has 30-40 RX7s in it, and the owners are not all fools. Give us a break, even if we are on the East Coast.

 

THIS is interesting , !st gen owners are trying to just get a cool dependable car , 2 nd gen owners are trying like hell to impress 3rd gen guys , and 3rd gen guys trying to get somthing for nothing alah signing off on disclosres, no sue policy. is this what it is coming to. sorry Im from a different generation . IF YOU CANT DO IT YOURSELF GET OUT.

 

Or just invest your time/money with a rotary shop that uses sound technology and has lots of pro-level racing experience to back up their claims :-)

 

People keep buying engines from Hayes Rotary too...

 

I was waiting for some more info on this product back in '03 ,after popping a low mileage motor. After reading this thread I am glad I didn't go for it.

 

Were is Batman to chime in on this? I went round and round with him and all he kept saying was wait and see............................

 

He was trying to gain prestige by implying that he was one of the people "in the know", which wasn't the case at all.

 

Where's the prestige in knowing about a product that doesn't work, or at best, doesn't show considerable benefit?

 

couldn't you just use the counter weight from the Turbo II to fix the balancing issue???

 

Adjust your timeline. He was trying to imply knowledge of the product prior to anyone knowing what it was or how it worked (or didn't).

 

Any updates from anyone?

 

We have had a bunch of cars in the shop that have blown motors with this device. When tearing down these engines we have never seen so much carbon build up. Only news I have.

Jason

 

Jason, you mean a lot of people actually bought it?

And not trying to start anything, but can you make a distinction between those ppl w/ blown motors at your shop and those who are running the butt plug scam vs. the still-secret KDR Anti-Det device? Which one did the guys w/ blown motors have? Or was it both (in considerable numbers)?

 

Hmm makes since to me since there is less spark.

 

I'm not too surprised.. When I heard about them, I wonder why mazda never thought about it, since it meant less production cost, less warantee work, and less parts. Butt plugs sounded too good to be true.

 

All of the ones i have seen were KDR engines and there are a few variations to these plugs. Some of the cars actually had the plugs installed and the others just had the power cut to the trailing coils with the spark plugs left in.

Jason

 

Was there a distinction?? I thought they were same except KD just added tuning??

 

Here's a novel idea! Don't go to some idiot who can't tune a skin flute and go to someone who actually knows what the hell they're doing! How many motors does KDR have to blow up for people to come to the understanding that they don't know a damn thing about tuning a car?! Damn people, whats the definition of insanity??? Doing the same thing over and over expecting a different result!!!

 

This is the easiest question I've read! Go to PFSupercars and have Ray Wilson build it for you! Take a peak at my dyno sheet.
