I was checking some random info on the SA/FB and I found some interesting weight figures, around 2200lbs. Thats over 300 pounds lighter then the McLaren F1! Then it struck me, the 26B can put out 700hp as proved during lemans and again it's more then the McLaren! I'm sure that with a suspension conversion using the later (S8) FDs aluminium double wishbones and some weight redistribution we could take on the F1. Thats right the freakin' F1 people! Let's show why Mazda won Lemans! So, who's gonna do it?

Doable yes,

who's got the budget to purchase or make a 4 rotor? Unsure

Alot of modification will have to be done. and plus will be very hard to pass emmission with a 4 rotor. Most people that do it do it for race purposes only. A 3 rotor can achieve that power level also. and would be the more logical sence.

I have been secretly planning my own 3 rotor supercar design ... but won't be another 20 years of so till i can actually afford things, and understand suspension better. Its not the easiest thing in the world to do. But hopefully the cost of carbon fiber would of dropped dramatically by the time its that late

One problem you have greatly overlooked.... Yes, it may run with it acceleration wise, but will never top its 254+mph top speed, simple as that. A track like Sartha the Mazda would get its *** handed to it in a velvet sack.

Im Afraid i will have to strike that comment, all the horsepower in the world doesnt mean a thing if you cant get it to wheels. The same goes for top speed, all you would need is the right Gear-Box and the right gear's. A Titanium 8spd would work very well with a 700hp motor. The F1 has all titanium internals for its tranny wich makes it strong as hell and its only 135lbs dressed.

The short stroke v12 is fast but its all in the tranny that makes its top end!

I think that he was more refering to aerodynamics than transmission

254mph? Youre thinking about the veyron not the F1 and all it will take to increase the max speed is a new tranny with higher ratios. Well you would need serious downforce to keep stability a that speed though. How about a good wing like the one on the 787B? A carbon fiber underbody would be a good idea too. The FB would surely look weird but who will notice at 200mph?

Just lighten the crap out of the 787b.

It wouldn't just take a new tranny with different ratios. The F1 isn't RPM limited in it's top speed (btw. is 241 mph, as shown by Tiff, the host of Top Gear, British TV show for "petrolheads"), it's limited by horsepower. The amount of drag you encounter at 240mph is unreal. As you double your speed, you quadrouple your drag in air. Let that warp your mind for a minute.

And to the originator of this thread, how old are you, 12? Do you not realize how much money a 26b costs? A bare block from MazdaMotorsports is something stupid like 100k (a little bit over-estimated, but when you get into that range, what's the difference between 80k and 100k for just the bare block?), without e-shaft or rotors.

Also, think about the aerodymanics of the F1 vs. the FB. The F1 was designed to do well over 200mph. Have you ever had a stock bodied FB over 100mph? Talk about a lack of front grip and a scary *** ride. Just think about that at 253, what you want to hit. You'd never make it without some serious re-thinking of the aerodynamics, and i'm not talking about just slapping on a BD air dam and some side skirts. At 200+mph, you need to have a full body undertray, a rear diffuser, and a heavily reinforced front air dam so you dont' have it fold up and go under you.

Please, for your own sake, think about what you're saying before you speak.

Match it for weight, yes

Match it for HP.. well with a crazy-*** turbo 3-rotor or 4-rotor conversion I s'pose... tricky and expensive as hell, but possible. Don't forget that you need *everything* made to support that kind of power including the tranny as mentioned, but also the driveshaft, differential, axles, brakes (definitely brakes!!), which means bigger wheels, suspension, upgraded fuel system, STEERING....

So basically the entire drivetrain, suspension, brakes, fuel and engine. Once you've got all that done to match the horsepower of the car (along with some good engine bracing, and structural reinforcement to take the torque), and assuming you've got the power to the wheels by way of nice rims/tires, you then have to look at aerodynamics. My 7 floats the front end above 170km/h... and you're talking over 200 MPH! Wing wouldn't be enough. You'd definitely need a full kit, and to achieve stability at speeds like that we're not just talking "slap a bumper and some sideskirts on and eyeball it"... we're talking about getting into a windtunnel with scale models and designing a kit professionally.

After all that, what's left of your 7? Body? no... Drivetain ? no... pretty much just the interior.

Yes it would be an awesome car... but we're talking a project that is *easily* in the range of 100k if not higher.

Too rich for my blood.

Edit: Estimate = serious lowballing... I was writing my post when it was mentioned how much the engine *alone* would cost. So let's say 2-300k as a base minimum.

I know it would take crazy amounts of money to build a rotary supercar but wouldn't be less expensive then the actual F1? Besides we can still debate about how it should be cant we? Internet isn't THAT expensive.

I just remembered reading a post mentionning a custom build 4 rotor. The guy basicaly bolted 2 13b together, I think it was making more then 500hp. How that for a powerplant? And didn't Burt Munroe reach 200mph in is crapy indian? Gotta love that guy.

*sighs*

You can't just "bolt two 13b together".

What do you use as a centre plate? Where are the stat gears that support the "two middle rotors"? Where do you get the e-shaft? Tension bolts? oil pan? how do you connect the coolant holes from one to the other?

Start thinking it through one piece at a time and you'll start to see the complexity.

I think you generalize too much.

Hey I'm not the one who did it, but what I meant is that he used 13b parts to build a 4 rotor version. I know you cant simply bolt two engines together. It's not because I'm new that I'm retarded. Any other questionning of my knowledge or intelligence while were at it?

he said VS a McLaren F1 , the car , not the Formula1 race car.

and if you match the cost of the McLaren F1 , and take the same amount of money and invested it all in a crazy FB ( I'd go more for a FC, since it was able to go at a top speed of 238 mph in 1986 at the white salt desert in Bonneville).

but the smart choise of chassis would be a lightened FD ( dont forget you can spend over 500 000$ on a single setup !!



and they are right when they say its all in the gearing.
my 240sx/r33 skyline, i have the gts-t model with gts-t tranny but with gtr gearing. the highest i got it up to was 296 kmh on the Apexi rev speed with a small 375rwhp on the dyno.

RB_eater

Where did the formula 1 came in? I said the F1, the bmw V12 powered three seater car. Clear enough? And I know a FC or FD could make a better choice but they're heavier and I own a FB. FTW

Please point out to me where I questioned your knowledge or intelligence.

I simply gave you my account of what would be needed to accomplish the things you posted about in a very general way, then gave you my opinion that you generalize too much. Your posts aren't specific enough for me to pick out the difference between "He used parts from two 13b engines, plus a lot of custom stuff, to make a 4-rotor" and "He bolted two 13b's together to make an engine that had over 500hp"

The only view that anyone can make of you is through what you post and how you write it. If you post extremely general, misleadingly simple things, you should expect to have people fill in some detail and assume that you didn't know about it or you would have filled that detail in yourself in the first place.

Please think about your responses before you post them. I never called you "retarded" or questioned your intelligence, but to say that to the moderator and expect not to have your thread closed would question mine.
