Mazda officially announces Mazdaspeed6

[JesseSays]

no, it'll be a single turbo.......twins aren't such a good idea for use on inline engines.

the toyota supra is an inline 6 with twin turbo, what makes this diffrent?? besides the 4 banger coming in the mazda 6.

Awesome news. How can they only manage 6.6 0-60 time with that much tq? Must be a heavy ass-beast... 34xx? 35xx????

[jnorion]

Yeah, the 0-60 isn't great competition for the Legacy GT... it does it in 5.8 according to Subaru

Mmmm the legacy GT is also so damn beautiful

that's 6.6sec 0-100KM/H (which is approx. 0-62mph)

figure probably about what the V6 weighs (3300? I forget offhand), to account for the AWD, they're using the 4 cyl, it's not going to be that heavy. Is this thing twin turbo or what, the rumors were saying it was, but do we know for sure? I want more details! lol

read the product information link i posted in teh first post.

it's a 2.3 Direct Injection single turbo engine.

Still seems awfully sluggish, I'd have figured a 6 flat-ish. Oh well, should handle awesome

just leaves room for modding the drivetrain.

It's a 3L inline 6. Twins were used to speed up the spool, since any decently sized turbo for a 3L inline 6 that actually flows up top would have a lot of lag. If twins were better, why does everyone goto a big single?

For a 2.3L, you can get a good sized turbo that'll be fine on spool.

figuring that a base 2.3L Mazda6i is already 3042 lbs, and all the reinforcement/strutural/drivetrain/wheels, etc that they're doing to this thing, it's going to be heavy.

what are we looking at... 3200-3400? Holy crap thats a porker.

thats not my question, im aware that most of the twin turbo guys are going to single, but my question is why is twin turbo not good on an inline engine?

I think the big news here is that it is a direct injection engine. Compared with a similar port injected engine, direct injection generates more low speed torque in a normally aspirated engine and allows faster spool up in an FI engine. In a 6 cyl inline, this would sharply reduce the need for twin turbos for the purpose of faster spool up.

Additionally, both fuel economy and performance are enhanced and emissions are reduced. Under most normal driving conditions, the engine operates with an ultra lean A/F ratio. This is achieved by injecting the fuel late in the compression stroke creating a stratified charge with a rich zone around the spark plug electrodes and a very lean zone towards the periphery. During high load, high RPM conditions, fuel injection takes place during the intake stroke creating a homogeneous, richer, and cooler A/F mixture for more power and a reduced tendency to detonate.
