Bah... who cars.... Jesus Padilla would still wipe the floor with him... In a first gen... with a 13b.... naturally aspirated.... lol..

Efficiency doesnt necessarily mean fuel economy man... but no, that does not matter when building a racecar.

I mean the amount of time (labor), and cost ($$$) to produce this end result is excessive. To spend 20k and 200hours when all you need to do is spend 5k and 10 hours to get the same result (numbers are just for example) is very inefficient.

Why can't I discuss/debate what is in the video? It's not your car, you didn't build it, I'm not knocking you here. I'm discussing the said project. That's what this board is for, no? To discuss, learn, and teach? Not to post vids for everyone to give one word responses to. :-/

This car burns 91 octane, I dont see many turbo/twin turbo fd's making that kind of power on pump gas.

I live in Ga and I can say that i've seen over 10 fd's with 450+whp here.
0-500whp 2.6L rotary's.

Like I said "too each their own" I enjoy seeing these amazing works of art. If I want to see a 500whp turbo fd i'll go to nopi.

 

[warrier04]

cool, but as mentioned, you could put together a much meaner mazda with the money and time invested in that rx.

 

[jersey_emt]

The fact that he has something entirely different from what is considered "normal" makes it worth it. True, 500+ HP 13B's are not "cookie cutters" but there is a good number of them out there. How many people can say they have a 500+ HP N/A rotary?

 

[UnNaturalinc]

But really.... who the eff cars if its entirely different? Why are people so out on a quest to be "non-mainstream".

It sounds like an ego issue to me.... For someone to be so obsessed with "being different" they throw all kinds of money down the drain and a crazy amount of man-hours just to make a couple kids at the track say "wooow!"....? Really..... why?

Who cares though? Do people build cars to impress kids at the track or build cars for fun and speed? I can understand someone wanting to do their own thing that hasn't been done a million times (i.e., civic hatch w/ B16), but to be that over the top with it seems kinda stupid to me in all honestly.

And different shouldn't automatically equate to "cool". I could stick a Geo Metro motor in an FD... yeah, it'd be a lot of work and it'd be a slow car. I'd be different though, right!? (I’m being factious of course)…. –hope I spelled that word right. I will at least give them props for going an off the wall route w/ an RX car and STILL keeping it rotary powered. hehe

However, my opinion and view on this whole thing would be entirely different if that car was actually running impressive times.... There are 'sport compacts' trapping at 220mph running 6's now! Although I don't know the stage of completion on that car, nor do I know what it's current times are. I really don’t know anything about it. I just thought it’d be a fun debate. No worries mates.

To be different..... what's the fun in having a cookie cutter car? I mean the damn thing runs 10 sec quarters....there's turbo fd guys not running those times. too each their own, i would take a big block chevette over a blown camaro any day...it's called enjoying your hobby an bringing new things to the plate.

not to be different althought thats what some peopel would think. probally as a show car or a street car you could brag. but in real racing there is a distinct advantage

hence why mazda races with a 3 rotor NA and 4 rotor NA

1st advantage is that a NA motor has a better response then a turbo car...although modern variable turbos like porsche KKKs can produce power in nearly any RPM range. those turbos are also expensive and complicated....and need rebuilding every X amount of miles.

But the biggest and best advantage of running NA is the ability to make the car lighter. A turbocharger adds weight due to the bigger/more heat exchangers. the engine genreates more heat and you need more heat exchangers. this is why F1 was always happy (besides development cost is $$$..revs cost $$$) with smaller engines. The new V8s use smaller radiators/less material and shave off some pounds off the car. doesnt sound much but given that 750 hp V8 is now just as quick as 950 hp V10 speaks a long way in F1 this season. They might lack torque in straightaways but the better balance due to weight allow the cars to break later/more affective and have a very fast cornering speed. corner speeds are faster then the V10 days and thus you can win a race through corners and not straights. along with the ability to mount the engine more center and reduce center of gravity. all this vehicle dynamics and weight add up to a well balance sports cars. Now weight in a normal street car isnt a huge problem but when your car starts weighing in at 2400 lbs then its important. plus with a front mounted intercooler the slightest damage to the coolers could cause the engine to overheat and eventually blow it up. water cooled intercoolers are useless in endurence races.

And reliability due to the heat is poor compared to a NA car. there is a pecise command and feel about a high reving NA car. Watch Best motoring "Battle at 10,000 RPM." Or even the new 5th gear. Where the slight move of your foot and the car jsut takes off. but with lower torque like ferraris and RX Mazdas...yeah they have the torttle response but without the craziness of too much torque for a light small car.

Of course without a turbo a Rotary motor will lack torque. And thus is needs more rotors. this is why they chose the 20B NA motor in Rolex 24 hour series. They didnt want to use a turbocharger becuase of the reason explained. And a NA 2 rotor in a RX8 GT tube chasis will not generate the torque or the reliability needed to compete 24 hours non stop. when your engine is running 24 hours relaibiltiy becomes an issue. And funny part is rotary gets a bad rep for relaiiblity becuase peopel try to pump out 500 hp from 1.3L. But most peopel dont know realibitlity is mazda's name becuase Mazda made their name racing in endurence races with rotary engines. Bathurst 24 hours, rolex 24 hours, Lemans 24 hours and etc. all won by rotary mazda that nearly never broke down. The RX7 is a Daytona legend

And as said before its a reliability issue. Its safer to pump 400-500 hp from a 2.0L or 2.6L engine then pumping it out of a 1.3L engine. These arent F1 engine that ran off 1.5L. theres only so much power you can pump out with what little room you have to play with. They would have to make the rotors bigger to have the abiltiy to increase the displacementon a 2 rotor motor....but that would hinder the ability to rev high which is very imporant for power/torque in a rotary engine

And thats why Bugatti engineers wanted a W16 engine over a V8. Bugatti said their #1 concern was reliaibltiy. And then you always get supra guys saying, "It took the germans 4 turbos and 16 cylinders to get 1,000 hp?" and how many heat exhancers did it take to make that car reliable? doenst it have like 9 heat exchangers?

just how much it takes to make 1,000 hp reliable

http://auto.howstuffworks.com/bugatti.htm

[FONT=arial,helvetica][SIZE=-1]f a V-8 engine is turning at 6,000 rpm, it can inhale a total of 24,000 cylinders' full of air per minute. If it needs to inhale 45,000 liters of air per minute, it works out to roughly 2 liters per cylinder-full. That's a 16-liter engine.

[/SIZE][/FONT]

Of course your average boy racer doesnt know much about thermodynamics and bugatti engineers/ VW engineers are one of the pioneers of 4wd and turbochargin engine. and they surely have more experience building cars/engines then some cocky rich boy supra owner who drives around in a 1,000 hp supra.

if it was up to every boy racer out there they would say why didnt bugatti engieneers use a 2JZ or 4g63? Why such a big engine when you can do the same thing with a smaller engine? Same reason why the Koeinsegg CCR keeps breaking while producing 800 hp. And even the CCX is still having its problems. Mercedes isnt having any problem making 800 hp form its V12 which is why the next zonda maybe powered by the next generation Mercedes AMG V12 making 700 hp. not some 4 cylinder or 8 cylinder.

Shut up dude, it's not even about that. It's called a discussion/debate. That's what this board is for.
