Turbocharged 1150GSA

[Fanum]

Modern superchargers can only be an improvement over the old vane type blowers we used to use. So there may be advantages in that direction but I doubt it

Surely the smooth power boost a supercharger delivers is better for a normal, rideable bike than the sudden and steep boost you get from a turbo??

Good blowers were hard to come by while I was having a play, i agree the supercharger may be the way to go if you want a smooth power boost, the driveing of the supercharger was often a problem, adding weight, complication, and absorbing power, modern systems must be better but why not a NOS system?? I you only want the odd blast you could gain 30bhp at the press of a button, the bike would be pretty standard apart from that and still be relable enough for everyday use.

The GSX i built would lift the front end at around 160mph (depending if I hung on to the gears or not) at the end of the 1/4mile, it ran 5-7lb boost and a very basic Nos system, God knows what it would have done had it been sorted properly, very scary on the road

To add to Sheps excellent input, "steep" boost is often indicative of having a turbo unit that is too large to be ideal. Don't forget these early systems were designed around available turbos of the day. There are several ways smooth the response, the first being smaller turbos that are now available, variable vane, variable (characterised) cross sectional area of the turbine inlet as well as afterburning. A lot has been going on with turbos since the 80's & we may see their return to bikedom.....

Why?
Please explain to me, i'm curious.

The GS gear box was only designed to take 80 Bhp if you strap a turbo or supercharger on your effectively doubling the horse power which starts to make things unreliable the motor would probably stand it but gear box and final drive wouldn't last too well.

No real firm opinions on them then Bill?

Erm...in fairness, I haven't had anything whatsoever to do with them.....

My opinion has just been formed over a couple of years that I've watched their web site.

I'm sure they are 'the experts', I'm sure they know more than anyone else around, but their website makes me bristle...it's just so bloody amateur, reveals (to me anyway) a petty and totaly unprofessional attitude and doesn't do them any favours IMNSHO.

Every company in the world has had bad dealing with suppliers/parteners etc....As a potential customer though, I really don't want to see that, all I want to see are the facts, the figures, the pictures, the endorsements, NOT the slagging off and silly personal stuff....that just belittles them and I can't help feeling that they're a one man band with a big chip on the shoulder,even if they're not.

They may well have the best Turbo systems in the world for BWM's, but they have the crappest PR/Web content design ever.......they should call MMC and ask him for a revamp then I'd probably be knocking at their door

Until then, how can anyone take them seriously with all that sniping going on???

I must admit my alter ego would love to smoke a Squid on an RI whilst riding a plodding GS....

Not dead yet......

Fantastic, a man after my own heart, I too would love to turbo a GS or may be even supercharge one, but unless your gonna blue print a gear box with forged parts I still don't think it will be reliable, your comments please Älgen?
And Älgen a couple of questions, do you have water injection and what did you use for ignition control, a stand alone ECU?

Anybody see the Turbocharged GSA 1150 on MCN a few issues ago?

I've recently changed from a Honda CBR1100 Blackbird to a GSA1150 and, while the GSA is a far more useable bike, more suited to my needs on the roads I ride on, I really miss the ballistic insanity of the Bird.

All of which has me thinking, wouldn't it be great to have superbike performance on a bike like the GS. You could blast down Autobhans with reckless abandon, do power wheelies in first, second, third, scare the bejesus out of crotch rocket riders (we already do in the twisties) etc., all in the relative comfort of your GS Armchair.

Am I right in thinking that fitting a turbo could shorten the life of the bike (and mine) if one was to mess with the dark side? Final drive failures? Blown engines? Worse? Not to mention the cash that you'd probably have to soend in beefing up the suspension.

What do you fellas think? Any experience with this stuff?

Totally agree.

The bike have done 60000 km now and 20000 km of them with turbo. No problems so far with the gearbox or the final drive. But, if you realy use the power you will toast it sooner or later.

For the other questions you can find the answers if you a search the forum.

Maybe for you it is if you have a turbo on your GS.

I'm crap at computers and can find didly squat on the search,

Give me a link will ya?
