Rotary Low End Power?
I keep running into useless kids who keep ******* on Rotary motors. Main thing I get is Rx-7's will never have good low end power or rx-7's will never produce enough power. Another thing I get is rotarys suck because you keep having to replace apex seals. Any Ideas on how to shut them the **** up?

well first u are going to start up your car and park with ur exhaust facing their front bumpers put it in neutral and start off slowly by giving it just a lil bit of gas then rev slowly up to 8k rpms hold it for about 30 seconds just long enough to build up some back pressure then let off and watch their andys autosport special, bomex front bumper (complete with custom chicken wire to give it that intercooler look from real far away) melt away haha this may or may not work depending on ur RX7 but i know my FC loves to breath fire just give it a try if that fails backfire on them

The new 2010 rx8's motor is redesigned for better low end torque. and first and foremost thing to get better power over all is add a little bit of boost man. they love it. build your car right. who knows what you can come up with.

well, if "shutting these guys up" means that much to you, then the only thing you can do is get a T2 (or do a swap) and spend the money to get BIG torque. they'll change their tune to something else, or perhaps they'll shut up, but then ... what happens when someone spends more money and beats you? now, they'll start talking again.
if you're happy with you car, i say don't let fools control you.

lol
Btw, why do you need low end power? Do you not have gears? O.o

I don't like to waste my time with ignorant people although I have still been known to here and there. You aren't going to get low end power in a rotary without boost. It's a simple matter of displacement and we don't have it. They may as well be complaining about 1.6L Honda engine torque. Same problem. No displacement.
Just remember a Formula 1 engine only makes about 250 ft lbs of torque! You don't need low end power if you are geared to take advantage of high end power.

Turbos are for people with displacement envy.
Rotaries may not have good low end torque in stock form, but some simple tuning tweaks will fix that.
BTW - Mine makes about 90wft-lb at 1500rpm. Rises to about 105wft-lb at 2500, stays there until 5500, then goes up to ~120wft-lb at 6200 Then it tapers down to "suck" because of the sorry exhaust system (65whp/42wft-lb at 8500!) but that is getting fixed this winter
But yeah... 75% of peak torque available at idle, that's really crappy low end...

Does it matter what some kid says? The only situation low end TQ matters is if you have no top end. One of the nice things about rotarys is the way they can take advantage of "the good side of the math" when it comes to the horsepower.
