    Why do you need gobs of torque in a car that weighs in at around 850kg! That's fully street registered BTW. Good enuf for 8.43 down the mile. This Dyno comp must stipulate a max of 15 psi boost, this car runs a bit higher boost to give 700hp.

    www.pacperformance.com.au

    Check out the vid's page
     
  5. WHATS THIS???? TURNING UP BOOST GIVES HIGH HP/L???? Well, i guess you can crank the boost to high heaven and get low 1/4 mile times, but the more boost, the less times it'll make it down that quarter mile.

    Dont get me wrong, I like this car and rotary engines, but most of the time, cranking up boost to get ridiculous hp/l figures makes for a short lived engine. It's pretty cool... for the few minutes that it is running.

    Der
    Of course winding up the boost gives out ore HP, like increasing/reducing the pulley on a supercharger. And yes, it's primary purpose is for strip which means the motor get's pulled down reguarly. I know of a few who do it after each meeting.

    Screw the rotary??? Man, you need to look at www.pettitracing.com ...Try saying that to their 240 Mph RX-7!

    Torque don't matter, HP is a measure of your engines ability to make torque and put it out. Rotarys make kick ass torque anyway.
    With 15lbs a 2-rotor makes maybe 300 lb ft ... so whats your point?
    Show me a 1.3 litre piston engine that makes that much.</b></blockquote><center><hr width="90%"></center><!-- END QUOTE -->

    Umm dude torque does matter you generate it by the amount of power used. one horsepower is 33,000 lb a ft per minute. Put another way, if you were to lift 33,000 pounds one foot over a period of one minute, you would have expended one horsepower. So you suppose to generate torque w/o it you are wasting energy to do nothing.

  9. God I'd love to have this car, or better yet, learn to build my own rotary engine, then make a 4.0L rotary engine, drop it in a very light car that I haven't decided on yet, and then scare people with it <IMG SRC="http://www.supercars.net/servlets/cMsg/html/emoticons/smile.gif">

    Oh to the person who said corvettes aren't efficient with the fuel, the 2002 vettes (What a kick to drive, best handeling car I've ever driven, and it throughs you in the seat) get 17mpg city and I think 23 highway, which is average for sports cars, I know my 4 banger MR2 get's the exact same millage. (well it used to, now it get's about 10)
     
  10. Screwing the rotory would kinda hurt dont you think. I mean its a cold metal engine. <!-- Signature -->
     
  11. I dont think 17mpg is very good, but with a big american car that aint bad. The RX-8 is going to have better economy because of what they have done to it, about 30% better. Also since its N/A it deosnt need as much fuel.
     
  12. How the heck did fuel economy get into this? I dont care if your motor is big or small once you try to get alot of power out of the engine the mileage is going to suck! Stop bashing American V8's for mileage. I am sure if you look at any other hi performace car you will see they are not any better I don't care where it is made.

  13. Hehe screwin' the rotary. Why can't these people accept that there is more than one way to power a car. <!-- Signature -->
     
  14. I have been reading up on this car and I must say the engine is quite intriguing. It is reported to weigh 30% less then the 13Brew. Interior ports have been enlarged and relocated giving it much better fuel economy. It will be interesting to see when they turbo charge it. I also understand that the balance is incredible making it quicker then the RX7 on the track. It has a curb weight of 1250kg or 2750lbs. The weight is not excessive so with a good turbo package sub 5 second should be easily obtained. Still not a super car but great little daily driver.

    On a side note:
    This may also be the best new conversion motor available to date for small cars.

  15. w/o a doubt a great little daily driver. i wouldn't her in my garage, if i had a garage that is, lol.<!-- Signature -->
     
  16. since mazda has been using rotary engines for over 30 years and they are suppossedly so superior to piston engines, then why havent any other companies started using them? doesnt make much sense to me
     
  17. why would they make an engin they have no experience with. the rotary engine was origninally conceived to be a form of forced induction. it is superior because it has fewer parts therfore less friction = more power. its displacement is equal that of about 2 to 3 times of its actual displacement.
     
  18. Actaully, it has huge amounts of friction, due to the total amount of metal seals rubbing on the housings. Each rotor has 3 apex seals, the width of the rotor. Then there are 6 corner buttons pre rotor that rub on the housing. Then, depending on year of engine, there are either 6 or 12 side oil control seals per rotor. Of course, there are also the huge center bearings on both rotors and the huge bearing surfaces for the eccentric shaft.

    Each rotor has 3 combustion faces. The rotor spins at 1/3 "crank" speed, but with those 3 combustion faces, actually has a combustion event once per "crank" revolution, like a 2 stroke. This nakes it's actual working displacement twice it's rated displacement vs. a 4 stroke piston engine, putting the 13B at the equivalent working displacement as a 2.6 liter V6.<!-- Signature -->
     
  19. What this car needs is some damn pistons. And more motor. I like a lot the motor that it has some modifications could be done and the outside is just perfect looking.<!-- Signature -->

  21. Someone asked why other companies don't use the rotary engine.
    The reason for that is, because Michigan didn't support the rotary engine back then!
    That's why there are so few RX-7's in North America, while in Japan, they're everywhere. Also why no other companies moved towards the rotary engine. But hopefully things will change in the future!<!-- Signature -->
     
  22. the person that said that rotarys suck its wrong
    I live in Puerto Rico, we are almost like a colony of US.
    I am a great fan of cars, I own a 73 Camaro that makes 11.4sec
    passes in the 1/4 mile, but i got to say rotarys rule.
    I believe that most of you doesn't know where my country is but
    I'm sorry to tell you that here is were the sport compact drag racing
    was born. there are a lot of rotary powered old datsuns and toyotas that make 8secs. 1/4 mile passes. And we have the fastest drag car with a 13B engine using carburetors, the recrd is 7.66@176mph, and what I believe is the quickest rotary powered car, a car with a twin turbo 20B that resently ran a 7.13@189mph
    <!-- Signature -->
     
  23. What, did you say. Screw rotary. You must be crazy. These people afraid to race my turbo 2 rx-7. My partna have a stock rx-7, and he tear up a 300zx. He give the 300zx, 2 from the back(that means, the zx start from 2 car lenghts behind of the rx). What happen? The rx-7 beat the 300zx by 6 car lenghts. Do you know what is 6 car lenghts. Imagine, rx engine way smaller than a 300zx. Shame. I does play with 300zx,mustangs, supra's, and probe. Because all of them slow. Only if i race on the high maybe the supra will win cause they are long distance cars. So never say screw rx-7, because they are the badest. if rx so shity then go race them, and see what will happen.

    You have one bit wrong, however. Piston engines (at least 4 stroke versions) make power every second stroke of the piston. Roataries make power every time the rotor face comes around.

    To compare displacements then, you either have to double the rotary displacement (it combusts every revolution) or halve the piston engine (which combusts every other revolution). Basically, at 3000 rpm, a single cylinder in a piston engine fires 1500 times a minute, while a singe combustion chamber of a rotary would fire 3000 times. A 13B (1300cc) rotary has the diplacement useage at any rpm that equates to a piston engine twice its size. TO compare power strokes, the 13B is the same as a 2.6 liter 6 cyl. (6 combustion faces). And it's pretty easy to get 250 hp from a 2.6 liter 6 cyl.

    About the 26B, that's the 4 rotor Le Mans engine. 700 hp in the Le Mans car. I've seen a few 4 rotor conversions from 13Bs, but nothing running near 700 hp yet in N/A form...especially not in street cars.<!-- Signature -->
     
  25. before i go off, i just have to say that i am probably the biggest fan of RX-7s and all other rotary powered cars, but i just dont think it is fair to compare theses 2 completely different engines on the basis of HP to litre, because we all know that rotary engines are measured all crazy like. So even though its fun to make rotary engines sound all pumped up, rotary engines take up just as much space as any piston engine in the engine bay, soo... say what you may
