Yeah--me too. I'd like to see that for real. I've built a couple turbo motors, and things will go bad REAL fast. I'm kinda suspicious the thing was way over carbed, and it was falling on its face and flooding out. I blew up a 5.0 twin turbo ford and it went from predetonation to a messy pile of parts in a fraction of a second. I do like what the guy did though and would replicate his work, but would downsize the carburation and look real hard at the turbo size. I have a draw through system from a SBC bob truck that has a very large turbo that makes great torque at 3500, but the boost gets too big past that. Great for towing, and makes a super muffler, and looks interesting. Needs some sort of rev limiter. I wonder if the guys still messing with it.

PA41; I wasn't trying to discourage you. I like different and odd also. That is why we are all hanging out here isn't it?. If you want to come to Rhode Island or can talk someone into it I will give you the one in my parts machine.

I'd like to see that supercharged Red Seal, or even better do it.. Weird is interesting.
PA .. not sure to be honored or insulted by you statement above but I have 6 flattys in my shop and do not have 2 grand in all of them [ all run ]

I'm mostly describing myself--(except for the blower on a flathead Ford), so its all flattery.

This summer put a crank and new lower end bearings in my sons SA200/
Continental F162,The only real issue was the end play shims for the crank,was a little tricky.

What's the application for the engine ? From your experience, do you think it would run a speedster?

This was in a 1960 lincoln red face welder. They're pretty tough little motors.
I know 8&9N tractors run a similar motor and rated about 25hp

The CJ2A I had would do a smoking 45mph(real deep geared), the 36 hp 1100cc 50s VW I had would not hit 55 (needed rings) and the 49 chevy 216 I drove of and on in high school, claimed 60 hp and would run about 60--but it was heavy. So in an ultra lite 1600 pound single seat speedster running a 25 hp L4 continental with 'hi way' gearing, you probably might hit 60 on a cool night with a tail wind, and couldn't get much of a ticket.

You may be surprised at the power you can get out of one with a little work. The 6 cylinder was supposed to have 71 hp if memory serves. I also don't think that the stock compression was very high so with a little head shaving and a decent intake with down draft carb(s) and a free flowing exhaust you shoulud do ok.

Yeah, that's true, the compression on flat heads can be real low. I was tinkering with an old tractor a few years back, and replaced the head (had a crack), and the tractor really ran great. Turned out it had a tractor fuel (kerosene) head that was 4-5 to 1 compression, and I accidently replaced it with a gasoline head. Rather be lucky than smart? Also I think fuel quality in the old days was real irregular and they designed the engines to run off the worst by lowering the compression. I bet the CJ I owned was one of the low compression 'multi fuel' wheezer motors. I put pistons and rings in it but didn't consider the compression. Cool old CJ--wish I'd have kept it. Found a pic of it.
