Looking for a turbo. Time to get serious

[WRT]

bottom line: you wont make reliable turbo engine out of a bike engine wihout serious internal work.

Do I have to point you guys to this again? Ok, he has done some internals, but (and I quote) "a surprising amount is stock" - and he's getting 306kw!! With reliablity. Way more than what you are looking for (altho I reckon he will be well able to hoist the front off throttle at 120kph . . . )

I suspect someone else is worried about their own swollen goods.

What the hell does that mean? Anyhoo, of course I'm taking the piss. Does anyone take you seriously?

Well my fragile ego was getting a little worried there that you might have been having a serious dig, and well... you know how I am when I'm not hidden away behind my leathers and dark visor... I'm just a frightened little boy really... with a pretty bike I can't ride.

Remind me to show you the latest stickers when we next meet, you might appreciate them

There's a few Mitsu turbo's out there that will suit a 750, the first that springs to mind is one off a E84A Galant VR4, that's the 2.0L v6 twin-turbo model, so each turbo is running off 1000cc's and even then, they are too small for the motor, running out of puff at 5500rpm, so on a 750, one of those (It's called a TD-025) would spool up nice and quick, and hold boost all the way to redline.

Alternately, you could find one of the Japanese Kei class cars, with their 660cc turbo motors and flog the turbo off one of those.

I wouldn't bother using a turbo off a old Sigma either, they are a single bearing, oil cooled only, piece of crap. Their exhaust housings are too big, and their compressor wheels too small, on your bike, it would just lag until about 8000rpm then only spool up about 5-7psi.

Having said that, I'm not a huge fan of turbo's on bikes, the last thing you want is to have to deal with lag coming out of a corner!

If the turbo is too small to keep up with 1000cc at 5500rpm, it wont cope with 750cc at 1100rpm.
With the lag your talking about, dial on sooner with the rear brake still on a bit. The drivers of the first Audi Quatro turbo race cars had to do it this way for years. Plus, anti lag aint that hard to build. An injector and spark plug take care of it nicely.
