More Power

Making your own turbo would be too complex wouldn't it? You have to balance the turbine correctly or else it'll disintegrate right?

There's an Aprilia Tuono with NOS which turns up at Meremere quite a bit. That thing has got some stick.

Who's seen the ghost rider clip with the 499hp turbo'd 'busa doing a wheelie at 300+?

Not to mention 1000's of dollars, be a bit of a waste of time seeing there are some small turbos out there
. some older forklifts have tiny little turbos - 2 cyl diesel, also som small diggers have really small turbos , the suzuki cappuchino is a 600cc turbo as someone said, the turbo on them is pretty small might be ok.

to fight the lag problem a roller bearing core could be fitted, also anti lag if you really want to get carried away, personally i wouldnt supercharge a bike (mainly cause of the complexity of the drive and the exposed belts on the ones i have seen, but would love to turbo one.

there are some really good sized turbos out there that would be perfect size on a thou, just have to hunt around for them, engine importers seem to stockpile them on a pallet and send them off to places to reco then sell as recoed units

Ghostriders turbo busa is an example of complete madness 1300cc - turbo 499hp at the wheel

Some twins just don't have the engine strength to handle too much extra power. F'rinstance, the VTR cases can't handle more'n about 125hp before they crack up.

Reckon one would be small enough for a minimoto or at least a little commuter bike? I want to get something small and cheap to modify so if I ruin it/blow it up it isn't so much of a problem as if I tried modifying the CBR

i wouldnt turbo a bike, without first fitting forged pistons(if the engine doesnt have them already) and fitting a head spacer plate to lower the compression for starters, and i would only personally turbo an injected bike, then get the ecu re-mapped.
.blow thru carb setups can only run low boost, due to the carbs not being designed to have 7-10 psi rammed thru them, drawthru carb setups you cant run an intercooler..

I have never seen one small enough to fit onto a minimoto, I had a thought that a small electric blower may be the go for a minimoto.

An electric ducted fan off an Rc plane may do the trick, run it off a microswitch at a certain throttle position, for a power source use lithium polymer batteries... , may need some sort of rising rate fuel regulator also, my mate has three daytona minmotos (hes gonna start to race soon) i might just have a word to him about doing something to that description

That's a good idea, might have to try that

[Mattyc]

Call either Ace Hobby on the shore, or Airsail in penrose for the electric ducted fan and batteries etc

I reckon that would be your best bet

[cowpoos]

That would be cool.


I wonder if the lag from a supercharger would suit a motorbike better, rather than having instant boost.

Has anyone considered NOS? Imagine being in sixth gear and hitting the NOS button

errr....there is next to no lag with a supercharger....

[Mattyc]

Very true Mr Poos's, the only downfall's of a SC are they do run out of puff at higher rpm, and they do use up a few HP to drive the actual SC the ass ripping low rpm boost would see the front wheel skyward a lot of the time.

another thing to consider, to change the boost of a supercharger you have to change the pulley ratio. on a turbo its as easy as adjusting either the wastegate acuator spring tension or using a bleed valve, or a closed loop electronic boost controller

[Slingshot]

Yes, you're right.

I got myself all confused!!!

[WRT]

Good testiment for the strength of a turbo'ed suzy . . .

[What?]

Supercharging a single or twin (maybe even a triple) has a major problem in that there is too much time where all the inlet valves are closed. This is not a problem with a turbine, but a roots blower will try to (and maybe succeed) to stall every time the air has nowhere to go. The result will, at the least, be broken drive belts. Gaskets will also suffer, and a high pressure system with weak (i.e. standard) valve springs could get real ugly.
