Please don't rev the **** out of your rotaries, there's no need to go way beyond the redline. I'm not going to go into the whole story, but the engine doesn't get sufficient lubrication.

 

well actually now that you brought it up, I am curious... care to explain further?

 

The reason MSD boxes and such make more power up high is because there CDI. MAzda found 8 PS in its racing PP 13B by switching from HEI to CDI (from SAE paper). I think it has to do with the rise up time or soemthing. Air gap sparkplugs insted of our semi surface dischage plugs can help it.

Speaking of high rpms, has anyone figure out how to get rid of the 7800 rpm rev limit? My engine is capable of ~9k now,.. but when i hit 7800 in the old motor it wa sliek a brick wall.... I'll have to try it again after breakin.

 

*shrug* I don't have the rev limit, I'm assming its an ignition limit, so a MSD box would solve it?

 

they already have diesel and natural gas etc rotaries... some company makes them, I think they are 4 rotor also. They call them stratafied omniverous charge rotaries or something like that.

 

is neone from Nj here? do you guys have ne rx7 meets? im from North Jersey (Bergen County) where and when is it...

 

hey i own an 87 t2...shifting from 1st to second at about 6.5k rpm it backfires...but it does shoot out flames really nice blue ones i might add. hehehe its sad to see other cars with those crumby backfire systems when a stock rotary turbo engine can do it all on its own.

 

Or is it sad that our cars are so inefficient that we backfire on stock gear in the first place? :P.

idunno how inefficient your ride is...j/k. mine works fine. does your t2 do the same?

 

14k = missing legs due to flywheel, unless of course he installed a scatter shield.

Which i doubt

 

probly i dont know he probly bullshits alot i have no clue... like 14k is a lil high unless he has F1 car lol... put some clips on of backfireing :o)

 

14k what WHAAAAT i highly dobt that just like alot of people already said the flywheel would shadder. think about the rotars not getting enoph oil and bernign the seals. i tell yah what my car is near ear peircing at 6.5 never mind 8 or 14. and yes id like to see some dyno results aswell as ur burnt up rotar housing!!!!!!

 

Just wanting to reinterate that im not the guy running "14k". I want to do a dyno run, but am DEFINATELY no where near 14k and am not the guy this thread is about.

 

yes yes but id like to see the dyno run of the 14k rev!!! in all fairness 14k rev would be prety sick!

 

Ken, you'd have to get a standalone or carb your car to get rid of the rev limit. I'm sure the ignition cut is programmed into the EC and not the coils..

 

Hey whats going on? I need to know about the Haltek doesn anyone know where I can get one and How do I get ride od my maf sensor. THanks Rob

 

Can I bock off the emissions on my 85 easily I have a bad egr valve and was wondering how that might affect it .

 

Its a 86 rx7 n/a

 

Um... hi.

 

Thats possible... what about going back in time to a dizzy?

 

i doubt that it would be more cost efficient or friendly to tuning to carb it and go to a dizzy, but it's a possibility..

 

Will the stock ECU still trigger fuel injector pulses if it can't pull a signal form the CAS? Basicaly, thinking out of box to run a dizzy and keep the stock ECU for fuel injection. This would bypass an ECU ignition-based rev limit. Wouldn't do crack for a rear-rotor fuel cut rev limit though...

 

Standalone or Carb.. I don't know if there's any hillbilly rigs out there though..

 

you haven't seen recent pictures of my engine bay have you?

 

Ken post some i would love to see some
