gs450 turbo size?

[Guest]

anyone ever turbo one of these little bikes? wanting to try something funky.

be a 4-500cc size engine build. trying to decide on the rest of the induction system for the turbo. cv carbs, vm carbs, mech/efi

and then that will determine my exhaust system.

i have found a few audis and saabs in the junkyard with turbos that i can source from.

a turbo 450 will run like a 650...
turbo something bigger to make it worth your wild

Well, he did say he wanted to try something "funky".

Instead of looking for info on putting a turbo on a GS 400/425/450, look around at what has been done to the GS500. It is generally more of a modded engine (I'm guessing because the entire bike is readily available). There is at least one turbo charged GS500 on the GSTwins forum, and I found a super-charged GS500 on Custom Fighters (although it wasn't finished online).

You make it painfully obvious that you don't know ANYTHING about turbos.

You need to match the size of the turbo to the size of the engine. Those Audis and Saabs have engines that are 5 to 6 times larger than the bike you are trying to victimize. The bike won't have enough 'oomph' to even spin the turbine, let alone spin it fast enough to develop some pressure on the compressor side.

If you really want "the world's fastest 400", first of all, start with a 400, not a 450, then find a turbo that is properly sized for that engine.

Good luck, post pictures.

"I think it could be worth a try just to see how a compact turbo twin would mock up in a motorcycle chassis...it would be cool if it ended up weighing like a 250 but accelerating like a 1000."

How about this one?

Honda cx500 turbo, look it up
These are a possible turbo that would be suitable.

OR get a supercharger from a modern seadoo.

Just rejet it for Nitro methane. It will fly

Back in the 70's, there was a 500cc Vincent single running the 1/4 mile under 9 seconds in England - Brian Chapman... supercharged and running nitro.
