With the latest trend toward more complicated engines (e.g. Ford going to all OHC engines), why not go the other way? Couldn't a company make a modern flathead and use a modest supercharger to overcome the inherent breathing difficulties? Would it not be able to pass air quality standards? Or would people just poo poo it? I think it would be great--a supercharged flathead six with modern fuel injection and electronic ignition. The supercharger would totally clear the exhaust from the combustion chamber (would need cross flow head) and cool the exhaust valves during valve overlap, then once the exhaust valve closes the injectors would juice it with fuel. And you could have dual spark plugs to ensure good burn on that extra wide combustion chamber. It'll never happen, but fun to think about.
[updated:LAST EDITED ON 07-Aug-02 AT 03:50 PM (EST)]Considering I wasn't a FTE member (or a truck owner) this time last year I think it's a pretty timely response! ;-) How did you bump it to the top w/o reposting? Or is it really that slow in this forum?
Um, what exactly is spare time?
I don't know much about super chargers but I'm always ready to learn something new... If I find out my flathead isn't rebuildable I thought about trying to put a T'Bird 3.8L SC motor in my '49... it'd be different. Would that unit work on a flathead 8 maybe?
I didn't know this post was at the top. I figured you were browsing very deep into the past posts. Might be able to retrofit the 3.8's supercharger. I expect there are companies that make superchargers specifically for the flathead V8. And there is a forum for them at this site where the folks would know how to help you set it up.
[updated:LAST EDITED ON 08-Aug-02 AT 11:28 AM (EST)]OK you caught me not really paying attention. I guess if you can call one page of topics digging really deep I was indeed doing that, didn't even notice the date of the post. :-) I just have this tendency to read everything I might be interested in on a site like this since there is much knowledge recorded here... some of it good some not but I read it all and decide what to remember, or try to remember where I read it when my CRS disease ain't too bad. I might even remember this discussion when I've had the flathead running for a while and decide I'm ready for a new project..... A supercharged flathead V8 in a '49 coupe would be a pretty good sleeper at a light next to one of those rice burners huh? Might have trouble keeping it hooked up though....
No, I guess I am the one not paying attention. Here I am telling you to check the flathead forum and we are already in it. That explains why you found my post not very far from the top. Seems there is not a whole lot of flathead discussion. But now I am thinking that you may get more info on hot rodding your flathead in the older truck forums for the years that the flathead ran (I think 1932 through what, probably into the 50s).
Well, if you can hook up with a blown flathead '49 the ricers would either have to give up or blow their little engines trying.
i have a six cyl flathead that has throttle body fuel injection
and electronic ing. i was planning to install a turbo but i was afraid that the rods wouldn't hold up. they were only made for 6.8 to 1 compression.the engine seems to make good power, i haven't had a chance to put the truck on a chassis dyno yet.
