So.. redline or not??
I've read that you should redline at least once daily. Not quite sure if this is true or not, but I took it as it was. My boyfriend said that you shouldn't do that with any car, even an RX8 because it will breakdown. Granted, he's never worked on or even driven an RX8, but he's in school for mechanics so I didn't want to start an endless debate with him.
Should you or should you not? That is the question. |
Everybody has their own opinion on it. Running all the way to reline helps blow out any carbon left behind, but may cause additional wear. Personally I reline my car multiple times a day because I believe it prevents loss of compression due to build up of carbon and its too much fun not to. Any ways your not going to get a straight answer, just do what you think is best.

I think the carbon is a myth.
You redline for fun. All engines are in the process of breaking down. |
Tell him to ask his instructor to explain about carbon buildup in a rotary engine. Ive learned to read and take advise from the forum, a gathering of true dedicated enthusiasts, over the advise of people who just "know about engines"
|
The redline is more for the transmission than the engine. That's why the auto has a lower redline. I've read somewhere that the renesis (your engine) can sustain 12k rpm it's entire life. Meaning it can run 100k miles+ at 12k non-stop. At 13k it blows. But like I said that's just something I've read in an article a while back. Constant high running is good for this engine. as long as you properly lube it it'll hold up just fine. Driving like a granny kills it. Shift at the beep a couple times a day. Don't have to push till the fuel cutoff. Just cruise till it's warmed up properly and then drive it like you stole it (exact words from the Mazda dealer) oh and don't let your boyfriend talk you into mods or repairs he can do. if you don't know already there's very little to mod on an 8 to increase power. Intakes are useless and there are no chips. Exhaust gives you very little. Only deleting the cat will show you a noticeable gain. So yeah redline her whenever the mood strikes you. She'll laugh and ask for more.

Vanity, yes you should redline the car but IMO, you should also be adding premix to the gas to lower engine wear. Ask any rotary shop that has been around and services cars from ALL kinds of owners, the ones that come in with the most carbon build up are the ones that are being babied. Redline the car at least once every trip once the car has warmed up. Any rotary motor will welcome it. |
From what I can remember of the article it said that at 13k the motor vibrates itself to pieces but up until that point it held up just fine. There's also an article around here, I believe it's in general automotive section, where a Mazda guru says that the seals separate from the rotor at low load low engine speeds. I usually cruise at 4/5k when warm.
|
It's the skyactive R thread I believe.
|
Some says redlining the car everyday is good, some says its not good, and some says you don't have to...what is it? Anyway, i never redline my car ever since i bought it, and its still running fine.
|
You don't have to redline the car but get it real close when going under a bridge or in a tunnel.
Amazing sound, you'll like it alot |
I bought my car from a 55 year old lady. A week later it was in the dealer getting a new motor. Dealership told me to make sure and 'rev' it every once and a while. I rev up close to red line two to three times a day..... Because I'm concerned about carbon build up...
Ok I'm really not I just like the drive/ sound! :rock: |
i say you redline the shit out of it, not only to prove your boyfriend wrong but to also scare the poop outta him. redlining the 8 wont do anything bad for it, its not a piston engine where crap will blow up everywhere, the car can stay at high rpms for quite a while. Heres a rx7 that the owner and his friends thought would only last some odd seconds at redline. little did they know the power of the little 1.3

Should you or should you not? That is the question. 2) NEVER worked on or driver a Rx8 (rotary is quite different from piston to add as we all know) 3) IN SCHOOL (not completed, currently enrolled. Still very much to learn...) So, that being said.... Would you take the general advice of the majority of experienced forum members from here many with years of experience if not more and redline daily, or his advice?... Just saying.... |

I don't know about that. I'm a bit weary on the 12k figure as well. I think if 12k were free on a Renesis, you would see alot more people trying to boost them and stuffing them in high performance Rx7 applications.
Im actually interested if anyone has swapped a renny into a FD(just for pure daily driving of course) Im afraid of posting the question of rx7club as id get flamed lol |
^there was a guy that did a custom build on an FB using the rennys housing, and the fc or fd rotors, some crazy custom build, he had nos for the turbo lag, and all his tuning was done personally. he kept all his data on his Palm device. He said it felt more practical than driving an FD daily

Should you or should you not? That is the question. Now hold on a second...you mean you can shift before 9k rpms? No wonder my gas milage sucks :hahano: In all seriousness though no one mentioned that you should let your engine warm up first before hitting the upper rpms. Warm her up first, then drive the hell out of it. |
^yes, always let her warm up before redlining, at start up there is no or very little oil being pumped into the engine, at a certain temp the oil starts being pumped in giving it much better lubrication.

A random redline a day doesn't do anything against carbon buildup.
It may prevents your intake valves from sticking but that's it. To prevent carbon build up you have to premix and actually drive your car hard for a while. |
^dont listen to that guy, his post count is lower than mine and he knows absolutely NOTHING :fruit:
|
Hey i'm not monchie!
|
obviously :lol:
|
actually redlining is good for both piston engine and rotary engine. carbon build up happens to all engines.
|
I always wondered whether a redline here and there would actually fend off carbon but I get the feeling just one redline would cause more carbon buildup than it would burn off. High heat is supposed to burn off carbon, and just one redline doesn't keep the engine hot long enough to have much effect. The intake ports opening is something that definitely needs to be used so redlining for that is a good idea. As for carbon build up... I say go to a few track days throughout the year =)
|
All I know is the last time I went to the dealer they had 3 AT RX-8s in the bay all needing new engines, due to carbon build up. I had my compression test done at that time which was perfect by the way. They told me a rev a day keeps the mechanic away. I’m following that advice for now.
|
Hey OP better keep your boyfriend in check. He's been PMing me lol. Also tell him to learn proper grammar. Might want to rethink him since he's nuts lol.
