everyone wants a peice of the evo/sti action

 

interesting!

 

This car will most likely be heavy, that's at least how the current 6 feels. However it's a move to the right direction.

 

"Mazda is prepping its own entry for the Subie-Mitsu rally wars—a 276-hp, 265-lb-ft Mazda 6 scheduled for a mid-2005 world debut. Spotted during hot-weather tests in the California desert, this sizzling prototype gets a twin-turbocharged and intercooled 2.3-liter four that is mated to a six-speed manual gearbox and sends power via all-wheel drive to 18-inch tires."-Autoweek

Umm I would like to be the first person to call Bull**** on this one. Twin turbo on a 2.3liter four. Are they saying they can twin turbo a 4 cylinder car??? and with a twin turbo, you better be making 300+hp.

Does sound cool tho if they can produce it.

Isn't the new Legacy STi a twin turbo 2.5L. It's certainly possible to TT a small engine...it also could be a typo or incorrect information.

 

Could be a sequential turbo setup.

 

Why cant they twin turbo charge a four cylinder car??? The Supra had a straight six, which shares the single bank design of a four cylinder. Twin turbos seemed to work fine there. The twin turbo setup on a striaght engine design is a senquential setup, and usually is designed to limit turbo lag. Your comment about at least 300 horsepower has no merrit. Adding more turbos doesnt just automatically equal crazy horsepower. Depending on how the car is tuned, and what purpose its tuned for, the twin turbo setup might not have that much more power than a good single setup. The twin senquential setup will be alot more drivable though, not suffering from the horrible turbo lag.

 

its possible with small turbos.. but that would make for one crowded trunk...

The curb weight of the base 6 is listed at 3045, which isn't too porky in my book. I assume we add about 300 lbs for awd, chassis beefing, and turbo/turbos additions bringing it in at more than the evo, but it is a mid-size car.

 

well i'm not an engineer but the way I see it is that the 4 cylinder is too small to fit 2 turbos. So if they aren't going for crazy horsepower and torque why the hell would anyone want to go to twin turbo set up???? how about someone with more knowledge chime in.

Also, if a twin turbo set up for a 4 cylinder is such an advantage, how come I have not seen any production car with that set up????? hmmmm.


I dont have any horrible Turbo Lag in my Evo. So i dont really see any advantange using a twin turbo setup.

I think this car is going to be awesome. I doubt weight will be an issue, I'm not sure if there is any aluminum on the 6 now but with an Al hood and front fenders that would help alot. I don't think it would be hard to get it close or below the evo's weight, plus the interior in those Mazdas are really plush, if they were stripped down to the evo's level I think it would show alot of weight reduction..
I drove some slightly modded (Edlebrock shocks and a different exhaust) 6s at the MazdaRevItup thing and they definently didn't feel very heavy to me, I was impressed, the wider stance made it feel more composed than the 3 imo.
One thing that the evo has is true rally heritage and the Mazda probably won't be as pure of a sports/race car. Like Mitsu, Mazda focuses alot on suspension/handling performance, time will tell but I'm sure it will be a fun car. If it comes here I give Mazda a big .

 

nevermind my post

i screwed up

 

Untill you have take college courses in fluid dynamics and turbo machinery, please mind your comments and refrain from judging how much knowledge fellow members have on the subject of forced induction. Of course your narrow mind cant see any advantages to the setup. I would expect nothing less.....

By the way, the overall size of the engine bay, not the engine, would dictate space. If it was senquential, and you actually knew what that was or spent the time finding out, you would realize the turbos are mounted in series going into the intake manifold. Besides piping, the overall size wouldnt be an issue, especially in a car as decently sized as the Mazda 6. Perhaps your assuming their twin setup would be much like that on a V8, with one turbo serving each bank of cylinders.....

Now can anyone with "more knowledge" chime in witha reply...

 

All the twin turbo RX-7s and Supras switch to one big turbo for crazy horsepower. Why do you think the twin turbos are for crazy horespower?

 

Woa...didnt see that coming. Should be interesting to see how it turns out. Now all Mazda needs to do is offer a boosted rx-8 and a hardtop miata.
