Hi the old ower of my rx7 told me that red lineing was good for the car. Can someone tell me if hes right? Also can soemone please tell me what i need to stop the car from flooding.

Thank you
Damian Parker

 

try a tune up first, as far as redlining (do not quote me) but i have heard that the rotory doesn't really redline till about 12,000rpms or somewhere in that area but someone else should be able to answer better than me

 

12krpms hahaha




The reason you wind out gears every now and then is to heat up the engine and rotors to help keep carbon off the rotor faces(carbon is a bad bitch!)

Its not harmfull if you maintain your car well and its in good condition still. Don't do it TOO often as that would count as abuse.

 

lol, if the redline was good for your car it WOULDNT be the redline...sustained/constant redlining = hurtin for certain motor

like he said its ok every now and then (like once each time while youre driving it or once a day...or a few times a week) but its not like u wannt to be going constantly 1st gear 7800rpm, 2nd 7700rpm, 3rd 7800 rpm etc.. ur motor will not be happy and will be needinga rebuild alot sooner

sure the engine can handle it but it has to be built to handle it... but redlining u get no power up there really ... all the power is made at 6500 rpm (unless u have s5 n/a or streetporting) so redlining is really pointless unless youre racing someone and want the power boost from higher rpm into the next gear

 

Tips on engine operation:

1. No hard driving until engine is up to normal operating temp. Nothing worse than driving an engine hard when it is cold. While engine is cold, try to keep rev's under 4k and no more than 1/2 throttle acceleration.
2. With warm engine, you need to exercise those 5/6th port actuators every once in a while. Taking it up to 7,000 rpm while accelerating in the first two gears won't hurt and will also help keep carbon from building up.
3. Oil level and a properly functioning cooling system are critical. Get low on either and reving your engine past idle could destroy it.

 

search. there are some long debates about this.

 

your engine is conditioned..
if you rebuild your and run it in good regularly.. then you wont have to worry about some old granny driving and building up carbon on the rotors from not going over 4K. Im nto saying just leter rip. like said before get a tune up and just do it more and more. dont lay on it.. 7K is fine for our cars if everything is prefect working order. I broke in a rebuild from 0km and did everything just perfect in my mind. It sees the twisties lots and seeing 7K with boost almost everyday. I have no problem taking the car out on the twisties and holderin her at 5-6K for an hour

 

i shift from 2-3k most of the time...
12k? holy ****, he sure showed his rev limiter who was boss

rotaries aren't any different from other cars in that regard... just make power at higher rpms...
speaking of, a friend's GTO still made power at 15k rpm's when he missed a gear... it wasn't great on the engine thow LoL

 

15k ... damn i would think the engine would have blown up!

 

my cars to old to have a rev limiter but if i had one it would be disabled

 

rev limiter? i have an s5. i never heard a buzzer or anything other than tires breaking loose. did it even come with it?

 

Your car should buzz when you hit redline, perhaps your buzzer is broken?

 

my friend took his 12a to 12k
doesnt make that much power up there though

didnt the first rotary engines spin to 25k?

 

...Rev Limiter? Tsk, tsk...I'm the REV LIMITER...

 

i some how find a way to hit redline seriously at least 5x a day during the week, then at least 40x times on the weekend. this is a minimum estimate mind you! seriously.. and my "used motor" has allready held up to 50K miles of that. granted the oil rings are starting to get a bit worn, and compressions down to around 95 all around but it still pulls fine! lol

call me abusive , and yes things do break, but im allways gladly fixing them as soon as they happen!! its worth the trade off, i get to drive like crazy ,and learn all about the car.


**yeah the first rotary did spin to 25K but it was a very different design. the rotor was stationary and the housing spins around it. its very weird....

 

you all have rev limiters. search.

 

Yea, I know that I had a rev limiter on all of the rx7s I owned, even on my gsl-se--*cries* I miss you baby...

 

my old '83 12a streetported engine can go 13k rpms without being hurt. but by 9k there's no power

Tito

 

12k 15k?...im not sure about all that . but you run the risk JUST like any other engine if you decide to redline it.especially with older engines with things getting old and wearing out.just be carefull,and please do a search and a tuneup...and please dont try to push your poor rotary past 8k unless it was built for it.

 

13k? how exactly did you decide that it wasnt hurting your engine? correct me if im wront but it must of been highly modified to endure those kind of stresses?

 

I have no rev limiter havn't in eithier one of my cars even if i did i would have removed it anywayz i wanna be able to put it right where i want it yes it doesn't give to much up in the high end but your start out at the sweet spot for the next gear and you def get upto speed faster

 

Where did you get that information. I've never read/heard or been told that. I've never heard of any Rotary engine doing over 13krpms.

 

I usually rev it to redline (or until buzzer beeps for about 10 seconds) once whenever I'm driving just to prevent carbon buildup. And I only do this when the car's warmed up. My engine's still pretty strong so I don't have a problem with redlining/don't believe it's bad for the car. ^_^

 

On a stock engine with Steel Apex seals you run the risk of having Seal to Housing contact at very high RPM's. Also on a stock engine they may not be enough oil flow to the main bearing at very high RPM.

If you can prevent seal contact or bearing contact then very high RPM's are possible, although there is generally no power increase.

Piston engines have redlines beacause at High RPM they will have valve float, chains or belts break or failure of any other critical mechanical part. Going into Redline with a Piston engine can quickly cause complete failure. Redline in a Rotary is not such a big deal.

 

i dont know what mods that were in there cuz my dad bought it from someone but a couple of times he'd just stomp on the gas and let's it whail. u'd see the tach reach past the 8 and stop - at the same time you can hear the engine rev more. now dont get me wrong, i know revving alot will hurt the engine but we both took great care of it and to this day it still going strong. i guess the previous owner rebuilt the engine when he bought it.
