now that's a response!

yeah, they have no redline, and their torque curve is a flat platue with a value of around 200 ft-lbs, constant all the way up to an infinite redline. as a result, rotary engines dont need a transmission. that's why our cars weigh 250 lbs less than a comperabley equipped piston engine, that and the engines weight less.

Most of the redlines are meant to keep the accessories from over spinning . But yeah, the little engine has limits due to the strength of the materials due to what the other people have said.

 

now is that where the redline starts or where the rev limiter is? cause I have a s4 non turbo and it hits the rev limiter at 8k.. and my old s4 turbo II did the same thing.

 

answer to question----- shift at 7k..OK LOCK IT!

 

i shifted my 87 SE when i couldn't stand the buzzer anymore, when dragging, upwards of 8.5k...i guess that might not be a good idea since the redline seems to be 7k...it's still running tho, i just don't own it anymore :P

Alright, this isnt first hand experience, but a close buddy of mine took a ride in his buddies modified 1st Gen EFI. He wanted to see how fast he could get the car going in second gear. After pinning it for a while, the car reached around 90 mph. He obviously couldnt read how fast the rpms were but the tack had wrapped around and was pointing in the low digits. He ended up shifting to 3rd, locking up the back tires and crashing the car, but thats not the point. These engines basically can rev for ever. If you feed them enough fuel and keep them cool enough. Although, I have heard, and seen on vids of rotary engines that explode from over reving. There's just to much inertia from the rotors that engine housing cant keep them inside and the rotors go flying.



Im not saying, go out there and rev them as high as you can, they will overheat and cause you many problems, best idea is to stick to the stock redline.

 

u r smrt



what the ****?



please disregard the misinformation in the above post(s).



13b's cannot rev to infinity and beyond, there are mechanical limits... it's been run over a number of times on the forum in the past I'm not going to rehash it here.

 

there's no redline, until your flywheel flys off and you are missig your legs

 

The redline of any motor is a factor of 3 things that I know of, strength of the parts, cooling (oil and water), and power.



The whole power thing is a big one because its a factor of strength and cooling. If your car cannot produce power in the higher rpms, it cannot keep pushing itself. Its the whole inertia thing.



Rotaries are limited by the stationary gears, oil pressure, oil cooler, apex seals, and PORTS!!!

 

dude i shift at 15k, and i shift mad quik too yo!
