If i remember right, Mr.Wankel used diesel in his first prototypes...
And diesel rotary engine is possible. I do understand why they wont do more experiments on that. Cause its basically old technology and there is no point to push more money on it...

Back to topic... Its awesome project. Waiting to see her finissed

Will66, Auxilliary injection is the holy grail of Rotary tuning in my eyes.
I can give you a ton of interresting articles on this subject if you want.
MAzda used gasoline to cool the insane exhaust temps rotaries produce. thats why they use more fuel. The rotary is 30% more inefficient than a comparable piston engine, cause so much goes up in heat.
Fuel has a cooling effiency of 750 (some unit i cant remember now).
Water has 4500
meth has over 7000.
Cause you cant ask the regular driver to remember to fill a water tank often, they opted for gasoline to help cool the combustion. This resulted in carbonisation, wich in time locks up apexes and causes compression drops...  Water injection steamcleans engine, and provides SICK internal combustion cooling capabilities. Also, adding water to a tuned program is hazard free, as water doesnt affect tuning as it has no fuel in it. Meth, you need to tune for. As i said, i have lots of info on this

found the numbers, got em mixed up:



Heat (BTUs) removed per gallon

Gasoline....................952
Ethanol....................2398
Methanol..................3136
Water.......................8087

Please post some pics!!

I\'d be interested in the AI articles too!

Listen, i will take your condescending tone lightly as i presume English is a 2nd language!
 
I am not talking from my point of view or knowledge, i have little!
 
I am talking from the experience of many tuners worldwide, probably many who know far more than you who and have highly reputable business\'s, why is everyone else struggling to reach these figures with the same turbos, but these guys have done it off a standard block!
 
Sorry buddy, but this info just undermines what we all presume to be correct on here!

That\'s a lot of arguing based on an arseumption

Are you going to be just using the car for steady driving or are you a b road slayer and take it on track?

Let\'s see!  Also have 2 wheels for track days so I might be torn...

Can I please borrow this typo?  I think it will come in handy LOL

I don\'t think that was a typo :Giggle

If it was a typo

Sorry Jet it was funny :p

Not really, its based on what just about every owner of a Rx7 faces when they go to get their cars tuned by our specialists, but hey, what do they know it would seem!

I\'m getting interested in this AI business, it does seem to make sense!

Hehe., howard coleman has convinced you? That man is a genious! ;-)

It makes a lot of sense.  I had to dig out an engineering text book that I haven\'t looked at since I dropped out of uni and ran away and join the Navy but it makes sense.  However it has me already planning my route to financial ruin.  Mounting the water tank in the boot to maintain weight distribution, 14 psi of boost, huge injectors and see where I go.  Maybe in several years time!
