Redlining my fc , is this a good thing ?
I was under the impression that redlining every every so often is a good thing because of the theory that redlining my rotary engine is a good thing because it will help to burn out carbon depsosits and keep it cleaner inside.
Is this true or is redlining actually unbeneficial to the engine longevity ?
when I say redlining I mean if you arent constantly (I usually shift from 3000rpm-6000rpms max because its a street car but you are a spirited driver by nature so you are revving into the redline but at times may be redlining to 7500rpm constantly (ex: topping out gears driving, drifting,racing, llaunching , etc).
I was told by someone that redlining it doesnt make much difference either because the engine is still wearing at lower rpms, just not as of high of a rate so if you never redline it it will still eventually break , but redlining it wont make that much of a difference on the engines life.
edit : I only redline 1st, 2nd, and 3rd gear. 4th gear i take to 7000 rpm i havent taken it higher.

An engine isn't going to last very long if you redline it constantly (racing), but it isn't going to last very long if you drive it like a granny, either (for various reasons... mainly carbon lock).
Find a nice medium.
Rotary engines in general tend to take redlining a bit better than piston engines, due to the design.

Today I redlined it through first and 2nd gear up to about 7500rpms , it accelerates nicely into 2nd gear, i let off after flooring into third and going up to about 5500rpm. No clue how fast I was going either, I dont have a working speedometer.
Usually I'll drive at 3000-4000 rpms , but sometimes I'll shift at 4-6k or redline it but , the higher I go the less often I do it. So redlining it is what I do the least.
edit : but you still didnt answer my question, is redlining a good thing because it burns carbon out ? or does this not matter that much where it would not be beneficial

what the other guy said is it isnt a good thing if you do frequently but it aint a bad thing if you do it so often. so yes redline your car every now and then just to get the carbon out.

id actually prefer 6000-6500 in first but then again i can't get traction in first at all anyways so i wind up having to granny shift to second but if you are drag racing then it's better to shift a little early in first than a little late as you will make up for it in second.

Recently my car lost a lot of power at higher rpm, (anything after 4k rpm) and ... I was on a trip to the store and getting pretty pissed why I lost so much power and I was in second gear @ WOT. It slowly climbed like usual till about 6.8 K when something happened and BAM my head snapped back. My power was back, all the way from 4k like normal. I dont know if I just had a clogged injector or what. But ya, it definitly helped me.

i think my car probably still makes power in the redline since its streetported and has a full exhaust thats why i rev it up to 7500rpm. I also have my 5/6 ports and sleeves removed, so all my power is above 3500rpm.
I dont really have any problems with traction in 1st gear and my car has an open diff with 205 50 15" kumho ecsta spt tires on 91 na rims
tweakgames - if your car is na your 5/6 ports could have been stuck in the closed position and then opened up when you revved it when you hit 6800rpm so you got all your power back above 4000rpm
