    After having my Twin turbo supra for over a year, then selling. It makes me wonder.
    What are the possibilites/options for turboing a SV650?
    I am new to bikes, and wont take on a task like this for some time, but I miss my turbocharged beast and would love that sound on the bike, plus the feel of a turbo, i just love it, any thoughts/opinions/info?

    you'd need a new crank, the stock one is only good for low 80s hp with any reliability (they break, not spin bearings). you can get aftermarket ones, but they're about $2k.

    Oh, and you'd need a lot more than just a crank to make any power turbo'ing an SV650. It would be a complete waste of time and money.

    you would need a lot more than a crank, true. however, the pistons + rods (if needed) are most likely going to cost quite a bit less than the new crank.

    it would be easier and more cost effective to turbo a newer literbike, even an old Air/Oil cooled GSXR.

    other than for the novelty, it would not be worth it. the complexity of that design would take more time and money, and probably end up either too fast for your available traction, or just as fast as the newer liter bikes.

    I think turbo lag is the last thing you'd want on a bike. It's okay in a car, where you don't have to worry about balance shifts from sudden changes in acceleration, but it could spell disaster on a bike.

    Besides, seriously, how much power do you need in something that weighs 450lbs including rider?

    Who said there would be any noticeable or significant turbo lag? He never mention what turbo he planned on using. Fail.

    Whatever dude, I just threw out a number. However much it weighs, it's a hell of a lot less than a Supra.

    He doesn't have to mention which turbo he'd be using. They ALL lag. Some lag more than others, yes, but whereas with an NA engine you open the throttle and you instantly get as much power as you're going to get, with a turboed engine you ALWAYS have to wait before it hits full power. It doesn't even matter if there's a wastegate or not; when the throttle is almost closed, the amount of exhaust coming out of the engine will NOT be enough to keep the turbo spooled, and so it will ALWAYS have to spool up when you yank the throttle open.

    Ah more of your theory backed by zero experience.

    Well, since noone else threw this out there.

    Turbos are not good choices for v-twins. The gap between cylinder fires is too long and you have to make up for that.

    Best choice for a twin is a supercharger. Less overall horsepower than a turbo (usually) but its generally linear and the power hits from the moment you turn the throttle if you use a positive displacement.

    Pistons can be used out of a Busa by the way with little modification. Doesn't help with the crank issue though.

    Oh, and realistically you only get about 100 to 110 out of a supercharged SV. If you REALLY wanted a charged SV you'd be better off to go buy a 1000cc version and stick a supercharger on that. Seen a few of those on various UK cycle sites.

    why put the money into an sv no offense unless you really like the way it looks for the money time and effort that you would put into that you could but a gsx 750 that would probably be faster or a liter and it would bo soo much more reliable

    Yes, not worth turboing a SV650. It has no high end, crank is weak. By the time you get it working, you could have gotten something much better and faster.
    I am an ex sv owner. It's a much better track bike than a drag bike.

    well, 600s are better trackbikes than SVs. the SV is awesome on the street though, because you don't always have to be in the right gear.
