Has anyone put a supercharger on a 4.7L stroker engine? Would the engine hold up to that amount of HP and torque? If so are there any dyno numbers out on it?

youd have to run real low compression, I think that it could work though....I think you could brace the engine with block hardener for it to stand up to that...but who knows about the rest...

I don't see much reason why it wouldn't be possible, but I'd keep to a boost limit of 5-6#, and would want to have a sonic check done before building the machined block (4.7L requires .060" over, IIRC.) Considering there are a coulple outfits that have taken the production 4.0 bore all the way out to 4.000" (requiring a ludicrous +.125" overbore!) there is no reason why it couldn't be done.

Preparation for assembly would be quite labour-intensive, as supercharged engines require thoro attention to detail...

Bolt this puppy on, drop in some 8:1 forged pistons, and you're rockin.

If they can wheelie an otherwise stock Wrangler with the SC, I'd hate to see what you could do with an SC'ed stroker in one. :D
