How can a 91 nissan 240sx stock beat a 1989 Mazda rx7 in drag?

i find it pretty hard to believe that a stock ka24de would even get CLOSE to trapping at 110.

as for double shifting........you might wanna stop watching paul walker. dropping at high rpm would spin tires. fishtailing does NOT give a good launch, this all sounds like a good made up story.

Maybe, but my 1/8 is 9.2 @ 74.6mph. Mostly stock, too.

when you say "trap at 110", that implies that they were on a track like responsible adults. i'm pretty sure it was more like two punk kids were street racing.

I still say Mazda and Wankle f-ed up in their figuring the rotory engines at the current displacements. I mean, it would be fine and all to use the 2 stroke method if it was in fact a 2 stroke. Think about it this way, a stock na 13B is rated from the factory at 160 hp @ 7k rpm, and 23 mpg highway, and 17 city. A KA24DE is rated at 155 @ 5600 rpm, and 27 highway, and 21 city.The KA as we all know is 2.4 liters, using the facts laid out for us, common sense would tell any self respecting automotive nut that the 13B is actually in fact a 2.6 liter.

Sorry, I just had to throw my 2 cents in, my sisters boyfriend and I have this argument all the time "Swears by the Wankle", and he is in fact a complete idiot. A perfect example to what I call "Blind Faith".

Plus, if Mr. stock dragster over here has a stock std hatch, he has a 260 pound advantage, and the added 2.3 inches in the 240s wheel base gives it a slightly better chance at launch, but that all boils down to the drivers ability to make use of it. Maybe the RX7 had a full 18.5 gallons in his tank. Never know, some people are silly like that.

No, I have owned both a turbo FC and a 240 and there is No way, I don't even care if the guy has a stripped down car. The turbo FC will win. period.

In my second gear i caught up to it by double shifting(eventhough it messes up my clutch) by third i already had the lead by 1/2 car as i was hiting 80mph@ 6.75 rpm by fourth it came down to luck because he was trying to catch up. over all the race finished @ 110 mph on fourth. so luckily i managed to take everything unnecessary such as front hood, passanger seat, back seat, subwoofer, amp, stereo, i know its a bit exagerating but one never knows to what extent one must go to win. right?
Your story is rediculous. and if you've ever owned a decent T2 you would understand why I say this.

I don't even care if "the FC has 100k miles on it without a rebuild" the FC will STILL be faster. Test drive one and then tell me this story isn't a load of crap.

I loved my 7's when I had them, especially my T2 mmmmmmm.....

sport compact car had a tech article about the wankel and they stated that based on number of power "strokes" per crank rotation the displacement should be considered a 2.6 (or twice the actual displacement, whatever it is) it basically is a two stroke. it has two strokes per crankshaft cycle (the crank spins 1/3rd the speed of the rotor or something)

i could be all wrong, i read that a long time ago and don't feel like checking my facts at the moment.

No no, you're right, I remember that article, I think it was Dave that talked about it. Regardless, it's still a damn 2.6 . Dave thought so too. I mean, don't get me wrong, I have respect for the engine even with it's flaws, but I can't stand people saying it's all that due to it's power to liter ratio. Honda was the first to break into the 100hp per liter world. If the Mazda engineers believed their own lies, they would have boasted that title in 1979. That isn't the case though, as I said, Honda Japan took that title 10 years later with the B16 powered Integra XSI.Like I said, I love the RX7s, and it is a true sports car, but any engine that is claimed to be a 1.3 while drinking the same amount of fuel as a Z24s 3.1 V6, is just wool over the eyes. Thumbs up to the RX7, thumbs down to the shifty lying Mazda engineers...

Smell yes, sound, well that all depends on the port job that has been done. I have heard some awsome sounding rotorys.
