Call me crazy, but i want a turbo 675, but who wouldn't

[Stardog]

Ever driven a turbo car? It is an on/off switch. NOT what you want on 2 wheels.

Don't care, I know how it works. Still want

I've had several turbo cars over the years. Back in the 80s a couple of Shelby Chargers, then a Buick T-Type (like a Grand National, but no intercooler), and even a Supercharged Bonneville in the 2000's (no lag with the belt drive). My dad had a Saab 900 Turbo; all or nothing on power, and an ass-load of front-wheel drive torque steer. All of these had slightly differing power delivery characteristics, and all exhibited varying degrees of turbo lag before power hits.

My current 2010 BMW 335i is a turbo (they call it a twin-turbo, not sure it is technically). Anyway, turbo-lag, and the resulting "burst" of power is pretty much non-existent now. It's a healthy and steady rush of power, good torque, good gas mileage considering the performance...truly the best of both worlds. Stock off the floor it will run 13.5 second quarter miles...from an inline six. 300HP/300FtLbs. A ton of fun to drive.

The two 80's era factory turbo bikes I owned had a lot of power...once you got them rolling. They were a handful to launch, and if you were heeled over in a curve and grab too much throttle...hold on. The new factory turbo bike stuff looming on the horizon is very exciting to me...no more turbo lag, and with the electronics available today, it should pretty much render them very rideable...literbike power with light weight, and some exclusivity...if they can keep the price in line.

I love it "The fruit flies have entered the meatloaf"...LOL

Triumph had that 675 at the IMS show. It's a clean looking bike.

Off topic, but man it sure is good to see "The Cape" back.

Supercharger > turbo
Supercharger = instant boost

whipple ftw

[LonestarCBR]

Supercharger > turbo

Not as much difference as there once was...and the turbo has that cool whistling whine.

Supercharger = instant boost

Unless you throw the belt (another story). Plus (mine did at least) it has a really cool menacing growl.

The coolest ever supercharger...on Mad Max's Interceptor.

Even better...a turbo feeding a supercharger...

Pretty sure you'd want that the other way around, and when you're looking to get that much air in your cylinders, it might be simpler to go with NOS.

No, you'd want the turbo feeding the supercharger. Superchargers tend to peter out at high RPMs and that's where turbos pickup, so having compressed air forced thru a system that wont compress it any further is what you want. that way you wont have any unexpected spikes in boost that might shoot a piston or a valve thru your crotch.

Having the turbo feed the supercharger (http://en.wikipedia.org/wiki/Twincharger" onclick="window.open(this.href);return false;) is the only way I've seen it done and it has been done. Basically a twin turbo setup is the same concept, but it would be considered a sequential twin-turbo. One larger turbo and one smaller turbo can be used to overcome the boost lags. The smaller one spools quicker at low RPM and the larger one creates boost up higher. There is also the standard twin turbo which uses two turbos that are the same size. One turbo would be used for each set of cylinders on say a V6 or V8. The turbos are mounted on the exhaust manifold so in the case of a twin turbo V8 for instance, you would have one turbo for 4 cylinders and another turbo for the other 4 cylinders.

[LonestarCBR]

I've read all of this...and I've come to a realization Miles...you need a twin-turbo V-8 in the 675 frame.

Regarding a comment I made earlier...the twin turbo in my BMW is actually a Parallel twin-turbo. A turbocharger configuration in which two identical turbochargers function simultaneously, splitting the turbocharging duties equally. Each turbocharger is driven by half of the engine's spent exhaust energy. In most applications, the compressed air from both turbos is combined in a common intake manifold and sent to the individual cylinders. Usually each turbocharger is mounted to its own individual exhaust/turbo manifold, but on inline-type engines both turbochargers can be mounted to a single turbo manifold.

For what it's worth.

[nitzer]

Yeah...damn inline 6 BMWs... You just have two scavengers on one manifold instead of two scavengers on two manifolds.

We had a 2013 loaner, the new 4-cylinder turbo. It's actually probably a better daily driver, not as hard-edged, but has a little turbo lag compared to the 335i. All in all, a really nice update on the platform. I can only image the 2013 335i model really rocks. Mine is really a fun car to drive...except the wife drives it most of the time. Almost 4 years old (May). We've got maybe 13-14,000 miles on it. And those a-holes at the dealership work harder than any bunch I've ever seen at trying to lure you into a new model while you're in for service. They'll loan you whatever they think you might trade to if they've got it available. They never loan me an M3 or M5 however. That sucks.
