Supercharging?

[onearmedbandit]

Expect when they let go. Which they usually did...

Our workshop has just fitted the first Sprintex to the boss's VRod.
Hasn't been finally dyno'd yet, but they're getting 140 hp at the wheel from 4 psi boost in the Aussie tests.
He says it'll light up the rear with just a handful of throttle.
With it's reluctance to wheelie, this could be a traffic light demon.

Do they make a version small enough to couple to a 250?

[Kickaha]

I just remembered Speedpro was doing a supercharged 125 twin,which he'd cut two cylinders off a 250/4

Wonder how much meat is in the VTR250 barrels? Wonder how far out in the classic rebore you could go?

Compared to the new R6, your bike will handle like a bucket of shite, no matter what front end you put on it. And even if it didn't, there's no road or track where the 80hp difference doesn't count.

actually its more than 80hp difference....

Awww man, I tried to wind you up with that days ago

Check out that thread two posts above... that guy went back to a turbo because he ran out of cash... maybe he'll sell you the little supercharger? Or at least let you know where he got it? Hell, sounds like he could fab it for ya... might need some money

i was dribling on a 748s monopost today and maybe i should get a real bike instead of my gutless toy? hmmmm

Say you did go the dkw way and use 1 cylinder to supercharge the other , it wouldnt need to be bigger because on a 4T it only inhales once ever 2 revs , but the charging cylinder (piston compressor) will exhaust every revolution. Maths isnt my strong point , would we get 7psi or 14psi from this arrangment (not taking volumetric efficiency into account)
If it didnt work properly you could use it to pump tyres, inflatable beds etc

That would be the smart choice... but hey, noone says you can't keep the spada too!!!

[ducatilover]

im sure my spada becomes increasingly parthetic each time i ride it! its freaking slow....i look foward to hitting 165kph after a billion ks on the straights....well its not that slow, but you get the idea

good point. <<

my spare Kawasaki Z1300 is going back together with a supercharger, I have bought one from a Toyota MR2 (good for up to 1800cc) primarily because it can be switched off, it has a magnetic clutch so I can switch it on whenever I feel the need, I am also fitting fuel injection and a 1500cc (wiseco) overbore kit.

With the standard power of the 1300 6 cylinder engine being 120Bhp I am not sure what to expect when she is bored to 1500 and fed with up to 7psi boost

One thing I am sure of, its gonna be fun to ride, I have ZX12 upside down forks, ZX12 Wheels and 6 pot calipers all round. I have to get the rear wheel modified to take the driveshaft system and make a new swing arm to accomodate the wider rear tyre. ZX10 switchgear and master cylinders complete the bits so far.

So loads of frame mods, engine mods, cosmetic mods and it should be ready

[ducatilover]

shit! i want to see and ride that

[classic zed]

I just have the fuel tank to spray on my Z1300 and the restoration is complete, then the boss (wife) says I can get on with the the other one, so it might be a few months before its done, just in time for summer hopefully.
Not sure I'd want to ride it on wet roads though

Originally it was going to be twin turbo charged i.e. 3 cylinders feeding each turbo, but I decided the supercharger would be better, if a bit more work.
