I think this quote sums it up for all of us with the mod.

 

I had this device put in as well. Tho I didnt sign anything, I was just told that you can run low octane gas with it. Which I never do but one more reliability mod wont hurt.

The issue in this thread which garnered my interest was the torque issue.

I dynoed with it and at 15psi I put down 325.8 RWHP and 321.7 TQ. Dave said that that was the highest TQ he ever saw on stock twins. He and Skip were also impressed by A/Fs. They just kept saying how "pig-rich" it was. I had originally thought I had the standard Pettit chip, since that was what I ordered from them. But Dave and Skip were like these A/F numbers are the same as the Unlimited chips we've dynoed here and that the standard chip leans out way earlier. I suppose it would have been beneficial to dyno pre and post detonation device to see.

Heres a list of my mods:
M2 CF intake w/ hard pipe kit
Unorthodox Racing full pulley set.
AC system removed
M2 large IC
Pettit chip (Unlimited, we think)
Jet-Hot coated DP
Gotham Racing hi-flow cat
Greddy SP catback
ACT street/strip clutch with 9.5Lb flywheel
Blitz DD BOV kit
Turbo XS manual Boost controller
All reliability mods plus a J&S knock sensor

My motor and turbos are still original with 45K miles. I had a compression test done and I was a hair below 8 across the board, which they said was good.

Im planning on heading up there after New Years to find out more about the device and sign this agreement if needed.

 

that is a nice trq number however i cant determine if its due to the mod or not. Our cars are almost identical. i have 40k miles, stock engine, and turbos and almost identical mods except i have a mp and pfc. I dynoed at KDR last spring and made 340rwhp and 304tq. My understanding is that u will make more torque with the highflow vs mp....atleast thats what i have seen on grpahs.
I would never knock kdr or anythin that they say is good...i am just trying to see if its benefical for my set up. Is the cost worth the benefit? My car is tuned to 11.3-4 afr's, i am safe (by kdr). If a car is tuned is this mod necessary? ..is the question

 

Good numbers by the way. Let us know what you run at the track this season. I cant wait to get mine to the track to see the trap speed. We all know dynos are all not the same, and 1/4 trap speeds don't lie based on Atmosphere. Then we will be able to compare dynos from various tuners and see which ones are registering low in comparison to others.

 

It saves you from accidental detonation due to:
- fuel starvation (tank slosh, fuel filter)
- a bad tank of gas (retards put the 87 in the 93 tank at the station - it happens!)
- just plain running it hard (dyno, track, etc)

And last I checked, $500 is a little less than a rebuild

According to Skip, he thinks the device may be available, to all, some time in early January. He stated that the patent process was complete, but he wanted to make sure that the "PATENT PENDING" would be enough to protect him from having others make it.

The device will be available to everyone. I.E. you can mail order it, and install yourself.

I got this information from a phone conversation I had with Skip on Monday. I am keeping my fingers crossed and hoping that these dates are hard. Hopefully, I will have one installed before Feburary.

 

500 dollars is very cheap peace of mind. took the car out yesterday because it was nice and dry and almost 50 degrees out. Man if felt great. did a couple of hard runs and the car is running good. If i didnt have the mod in, i wouldnt do nearly as many hard runs as i do with the car now. I think it just lets me enjoy my car that much more.

 

Will this device require a standalone such as a PFC in order to function properly?

 

hmm, you guys are all back to running 93 huh? From what's been posted, everyone knows that its ok to run 89 octane gas after the "mod". Is it true that 89 octane has less "additives" - thus allowing more power extraction? I understand that race gas has high octane, but I presume that is for detonation purposes.

 

you can use the device with a stock computer from what i understand. I didnt get the device to run 87 octane or I would. When my car was stock i put 94 octane in regardless, then when i get back to new york with my new turbo, they didnt even offer 94 octane at sunoco anymore. I was so pissed. A new law bands the sale of the stuff in New york and another state. If i could i would run the 94 but they dont sell it anymore.

 

Any uodate on this ?
Is it for sale yet ?

 

'The release date is "when it's done."" George Broussard.

 

why do the ban 94? aren't higher octane fuels better for the enviroment? at least thats what bp and exxon mobil say...

 

There are 60+ Beta testers with this product.

As u can imagine there are numerous years of RX7s and various mods and no one has lost an engine.

I suspect that greater HP/TQ numbers can be reached if a tuner like Excess Engineering in So Cal knows how to tune to the limit.

 

Since the device will allow a leaner mixer, it should run cleaner than stock.

 

When I talked to Skip, I told him to be super careful on flow of information, and encouraged that NDA's are a must ( I have provided him a copy of a "bullet-proof" NDA).

Some folks that claimed to have not signed the NDA must have built some good trust with Skip.

Credibility goes a long way and I can assure u that Skip is well aware of posts like this, what the community are saying and even the **** talkers *cough* Zerobanger *cough*

My best advice to those that doubt is to NOT talk **** until u are educated about the subject matter to back ur statements with FACTS.

BTW, I heard that KDR is in Amish territory....

 

well broussard is filthy rich after selling max payne...of course he can say that.

Didn't Carmack use that line long before that?

 

 

Im not sure...but carmack is in the same financial territory....dont like the game...hell, let's start all over....gabe from valve is the same as well.

one of these days I would love to be able to make a game on my own terms under the resources and power of my own company.

I am curious about this device. Its less expensive than water injection..thats for sure. Im going to wait another six months or more to see how the testing works out.


good luck you guys.

Sounds like a sweet *** device. Only thing i can think of on how it works is this. I know i read somewhere about peak torque on our engines is where detonation is most previlant. I think it just takes away timing at peak torque, thats what i think. Although you would have to dyno your car to figure peack trq, and program it for X RPM range. I dont know sounds sweet to me, dont know if ill need it becuase i may stay stock in fear popping another engine.

 

I'll do it because I'm stock and just one bad tank of gas would do the same thing, and I'm tired of paying $.25/gallon more for premium 94.

Well, I'd like to be the first guy in Europe to have this magic box on my car

 

I'm happy that people are still developing for the FD/Rotary RX-7. Kudos to KDR for being more than just a rotary repair/tuner place. Dave knows much more than working on FD's and does just about everything. I saw them rebuilding a 323GTX motor for rally. They've got lots of ideas, but little time to implement them.

We really need to hook up with our Australian and Japanese counter parts. They seem to have lots of great ideas as well. I'm sure rotary enthusiasts in other parts of the world could contribute a lot of information.

Hell, 4-rotor Scoot RX-7 concept/supercar. Damn digity! The rotary engines are far behind our piston counterparts in terms of development. It's amazing what Mazda has accomplished (in racing terms) with an engine so young. It took a long time for the LS1 to develop where it is today (without 427 form) and it is an excellent engineered piece of work.
