Hey all,

I just got a 2006 rx8 that redlines at 7.45, i was wondering when the best time to shift is.

Some of my friends tell me to not to go over 4.5 but i figured since it redlines so high that it doesn't hurt the rotary to shift after 6, but then again im new at this rotary engine.

Any suggestions?

 

7.5?

Is this an auto. and redlining it doesn't hurt it. You really should do it once a day or so. but it won't hurt to shift high. But if you're driving an auto why does this matter....

 

yeah its an auto >.< I know.

But i drive it in the manual transmission, i was just curious.

 

well are you racing or city driving ? Redlining at 7.5 won't hurt the car, but is bound to get you a ticket.

 

I'm just driving around, so if i shifted around 5 or 6 on a regular basis it'll be okay?

 

Just keep it in auto mode.

 

our cars already needed oil added because it burns it off, and redling is going to call for even more adding and quicker oil changes, I only redline when going to an on ramp or catchina yellow.

 

...thats no fun

 

Ahh good point Zum, Thanks for the info.

 

Just make sure the engine is warmed up before doing it, and make sure you give it some time to cool down after doing it

 

welcome ktown
hope you stick around long enough to be able to look back on your first post and have a bit of a giggle ....

 

Speaking of topping off oil, I need to top mine off; been 2200 miles since my last top off

 

^ i top off every 1500 half way between oil changes

 

Ya, drive nice and easy when first turning it on. But after that you can redline all you want. But if you think about it, doing it a lot isn't going to be "good" for your engine. Won't hurt it, but it for sure won't lengthen it's lifespan if you do it more than once or twice a day...

 

It doesn't really matter if you shift at 6 or even 7, eventually your going to have carbon built up and no compression down the raod before the side seals and apex seals fail. I did a little disassembly work this week results...... first day was 5 engines torn down, all MT, 3 carbon build up issues and lack of power/no start issues due to massive carbon, 1 engine was a simple oil leak(reman from south carolina plant), and one was ran with little/no oil and over heated aka everything is throw away(customer didn't check the oil). Today I managed 6 AT's in the time I spent there, 5 had carbon built up and low compression/lack of power/no start issues, 1 had broken apex seals on the front housing about 3/4 the way up the seal from the front.

Maybe 1/10 enignes is bad due to side seal/apex breakage, 7/10 is no compression/no start/lack of power, and 1/10 is overheated/low oil usually issues, 1/10 is a odd oil leak or something internal like gasket failure.

I wish it wasn't such a oily mess working there or I would do pics to show but I wear 2 sets of gloves to do the work, been months since I disassembled but same results. Mileage varied, some 90k mile enignes looked better then 50k miles motors.

Boring facts I know, I am fascinated and discussed with another coworker how the inner oil seal on the rotors themselves always look very well lubricated and the spring are clean yet every seal/spring on the rotor besides those look toasted and carbon built up insanely.....keep in mind I started the job by looking online the day before the interview to see how a rotary engine worked lol so its all new to me. We were discussing ways to make the exhaust ports different with a engineer and my idea ended up just being what the race engines typically do lol, aka wont pass smog that way I suppose but I wish I had the tools/equipment/money to experiment on the motor with my random ideas.

 

OMG.

It's a rotary. It should consume oil. If it is not, that is a bad thing.
The harder you run it, the more it should burn.
And the harder you run it, the less carbon buildup you will have.
Don't baby this engine, it does more damage then good.

 

I dont baby it, but i dont abuse it either.

 

i love you



i'm not saying SEARCH ARGH!!!!


but saying if you do some searchs for the faq's or the new owners threads and what not, they will tell you a lot. like redline once atleast day, check oil and fill up when necessary.
