I have heard a lot of people talk about how you should redline your 8 a lot or daily. I did not know if it was just different for the rotary engine because I have never heard or pushing your engine to the limit as a good thing?

well, these guys have had years of experience with rotary and i guess the 8 is the exception to redline being bad. it's certainly because it's rotary and it works very differently from how a traditional piston engine works. i'd take their word and i notice myself the car likes high rpm alot.

it's not going to harm the engine, but it might hasten damage to your transmission.
my syncros are now shot for 4th gear. When I get my new transmission in, I plan to keep it below 7k for the most part (which is fine because I make almost 300 whp at 7k). The transmission was not designed for this car - it's a modified tranny used in the miata.

Exactly what I've heard, its good for the engine but bad for the tranny!!! Thats why I've been through 12 output seals and mazda won't warranty them anymore! Ugh! So either I redline and screw up my tranny, or don't and screw up my motor!! What to do?

you don't need to redline it to blow out the carbon. 7k is good enough.
and if you turbo it, you can do as much carbon cleaning at 4k as a stock car does at 9 *

While it is true that the stress on internal components increases exponentially with the RPM in any engine, rotary engines are not nearly as susceptible as a reciprocating engine. Frequent high RPM use can also keep the engine clear of potentially damaging carbon desposits. So I'd guess it's probably more beneficial to redline a Renesis than not, but keep in mind that momentary "once a day" redlines for a second or two aren't sustained long enough to get rid of anything.

So, in your opinion, what's the minimum you'd suggest to avoid carbon buildup? Five to 10 seconds @ redline once or twice a day? Twenty or 30 seconds? More than that? And does it have to be at redline? Or is 7 or 8K good enough?

i tend to redline at least once a day.... when not redlining, I usually like driving down the freeway in 4th or 5th gear tops..... around 5k to 6k rpm....plus I like the sound of the Rotary

I've been redlining in 1st and 2nd a few times a day but almost immediately shifting after the beep. But the suggestion here is to keep it at redline for a number of seconds, right? I haven't been doing that. So that's what I should do?

Momentum Keeps Me Going
Here's the real deal. I've spent lots and lots of time around (+ or -) 9k rpm over 4 yrs. Hours cumulative time I would imagine. It doesn't hurt the transmission, improper use does. It doesn't hurt the engine, it doesn't hurt the seals...just be warmed up and don't bounce of the fuel cutout. Like other say, some good continuous reving cleans the engine.
My engine/transmission are strong, good compression, no problems and the reason it is is likely because I don't baby it/I don't abuse it either, I just use it like a rotary should be used...in the high rpm ranges whenever you need/want to
It's one of the main things that make the rotary so much fun
