single turbo
I havn'nt been able to find much info on slapping a turbo on a 460 in here. I have a new garrison T-12 turbo sitting on my bench now and need to know if this monster is too big. From what I have been able to gather, this turbo was intended for a Cat in the 450-550hp range. Will a turbo intended for tractor trailers and heavy equipment work?If not, what do I need to look for? Also, if anyone can hook me up with a web-site that can help me out with this project, I woul appreciate it.

I don't think you can use a diesel turbo for a gas powered carburated engine. I heard somewhere that the gasoline will attack the seal on the turbo and you'll have a quick failure of the bearing. However, I think you may get around this problem if you can blow through the carb - or use fuel injection.
You still will have issues with wastegate/blow-off pressures and a host of engine issues.
I'm certainly not up on turbocharging gas engines, so take everything I say with a pound of salt.

no name,
I know this is a few weeks old, but have you found anything else about turbocharging a carburated 460?
What about supercharging it?
I know very little about either, except what I read on 'howstuffworks.com'. But it seems like either could be accomplished on these bib blocks.
Any links or info on this that anyone cares to share?
TIA

Unfortunetly, I havn't been able to get any info. other than what you see posted here. I would still like to do it with a single turbo but looks like I mite go with a blower.

A turbo set up would be way cool and original. You're looking at a fair amount of fab work to get it right.
My guess is that your Garrison T-12 wouldn't work right on a gas engine. That T-12 is spooled to give max boost at a low RPM such as 1200-1500 RPM. If you strapped it on a gas engine and ran the engine out to say 5K (or even 3500), you'd pop the turbo in a heartbeat from excessive turbo RPM. This is just a generalization, but think of it like this... On that diesel, the turbo was probably spinning around 50,000 RPM under full boost/high engine RPM. You take that same turbo and strap it on a gas motor at wind the engine to 4000 RPM. At 4K the turbo would want to spin like 120,000 RPM.
I'll give the same disclaimer GR8 gave. I don't know any specifics on the T-12 so I can't say if it would be a good match for sure, chances are no.
I can't see how the seals/bearings would be an issue though. I've never seen a turbo or supercharger set up where the fuel charge went through the compressor.

You really need to read up on turbo's to get a handle on your engine's needs. I thought about doing this a while ago as well. First you will need to find your turbo's compressor map. Then see if it matches your 460's needs. I would not worry about blowing the turbo up, although meant to run at low engine rpm's the volume of exhaust from the CAT diesel probably spooled the turbo up into the 200K range. You may have TREMENDOUS turbo lag though if the turbo is too big. That is why the fairmont guy went with 2 smaller ones. A sequential setup would be cool to see, but much harder to engineer.
