Turbochargers?

[craigs288]

Does anyone on this website have a turbocharged bike?
If so, did they buy it ready to go, or put it together themselves?

What I am after is hopefully someone is a bit of a know-it-all ( or at least know-something).
I'm hoping if I post as many details about my turbo, i.e. A/R numbers, inlet and outlet diameters, maybe even a digital photo, that someone will be able to give me an idea of airflow/horsepower potential.

Anyone?

Send Fizzerman a PM - he is pretty keen on turboing one of his bikes, and seems to know a fair bit about it.

turbo charging bikes is a real bitch ive been told. Supercharging is the way to go.

Death has a turbo.......spends most its life in his gargre though



The FSAE used a supercharged R6 engine this year in their vehicle, so supercharging is a viable alt for bikes.

[R6_kid:Me]

the FSAE supercharger cost them around $5k, then they had to engineer the extension to the driveshaft to power it.

However, the supercharger has no lag whereas a turbo on a bike might be too large and have lots of lag, or spin up too fast and wear our very quickly (or reach full boost way before your redline).

In principle it is easy to do...not so easy when you go to do it!

I've got a SC14 in the shed, destined(?) maybe for my 4 litre falcon, but I had been eyeing it up for the bike.
But there is nowhere really to put it. It doesn't quite fit in front of the engine and it doesn't quite fit behind it, even with the carbs and airbox out of the way. The frame is too narrow and I would need a tricky pulley setup off the altenator as its the only convenient direct drive from the motor.
Could drive it off the drive sprocket, but that would give a boost increase with each upshift.
I'll PM Fizzerman and see what he has got to say about things. Cheers.

Also check for superbike magazine from the UK, not sure if they have a website (im sure they do) but they had a couple of articles on a company in england that does bolt on supercharger kits i think. One of the bikes may have been a 1200 suzuki but dont take my word for it. Just remember a Z1000 that was pushing 200 and a bit on a baseline charger kit.

if that worked it would be rather interesting to ride!!!

Our supercharger (FSAE) was probably one of the best decisions we ever made. It has turned the high revving R6 powerhouse into a angry torque monster. While breathing through a 20mm restictor we are making more torque at idle (3000rpm, 69Nm) than the standard R6 engine was making at full noise.

So I can only imagin what would happen if you were to put it onto a more tourqey motor...

In saying that I think bolting on a supercharger is a lot more work and engineering than a turbo. But if your serious I think it would be a pretty good option. You are welcome to come and check out our setup if you are interested. Just PM me. Engine is in bits at the moment but Im sure our engine guys can talk you through it.

An bigups to the R6 engine... how bout 12.4:1 compression and 12.5psi boost sound? And not a hint of knock anywhere

I went to google and typed "gsxr100 turbo".

Seems there are a few guys in sweden with nothing better to do than turbo a few of these old monsters. Most are blow throught carb setups and look very do-able.

For your size engine you'd want a garrett GT30R or GT35R. Or a turbo that is equivalent to that one. There are guys doing things for GSXRs and being your bike is a GS it might give ya some ideas.

Here is there site http://turbobikeresearch.com/index.php?&

Also R6 Kid if a turbo is setup right it can be almost as good as a supercharger off the line and has better top end. And not having it mechanically connected gives some advantages as well. Getting full boost before the redline is also what you want otherwise you are not utilising what airflow the turbo can give you over your rev range to get the extra power.

Also with this new injection tuning thing the motorbike shop has in chch if a shop near you has it you might not need the computer, as they could remap your one.

There is so much bs on this subject I'm a bit reluctant to give advice on the forum, but if yer real keen (turbo's work fine) pm me and I'll give ya my ph no. so we can discuss it properly.

I've a turbo bike - a Suzuki XN85 factory job, it's injected, not carb'd.

Also seen a supercharged V-Max in Dunedin a couple of years ago , it seemed a natural for it but don't know the details.

The turbo turned up today for the new Z1300 project. Its a custom made IHI VF24 as used on the Subaru's, Ball bearings on the shaft, back cut steel turbines to help them spool up quicker.

I am putting it behind the engine so that I can run the two, three into one headers down under the engine, then join both headers into one before coming up behind the engine and into the turbo. I have to make a custom inlet manifold for the fuel injection so that everything matches up.

Turbo is good for about 240bhp so Im told and uses mimimal oil from the engine to feed the bearings.

As you can see its still in the mock up stage.

should be fun
