    Since we're throwing around this engine, I was wondering about the L67 supercharged 3800? Yeah I know the throttlebody on the Eaton blower faces backwards if you put it in a FWD application. Either a elbow to face it forward (or even something crazy like hooking it into the pop-up cowl vent just for fun heh). The advantage on the supercharged version should be power nearly off idle with the Eaton. If I have this right, it'd probably require a 60 deg v6 bellhousing (according to Wikipedia). It'd be a bit of a complication putting it in all injected and such but I think it'd make a pretty fun motor for the old 5. Probably nothing I'll be doing soon due to health and finances, but I like the Eaton supercharger quite a bit. Heck I wouldn't even mind seeing one on the old dauntless just for grins, add FI with welded in Injector bungs, fuel rails and maybe something like the Megasquirt to control it. Just some idea's, perhaps good, perhaps bad, but fun I think. :D

    Can I say something here
    Jeep made it's reputation with a 60 HP engine in WWII
    they used torque and gear reduction to make a vehicle tha could go anywhere
    I think the point of diminishing return on the HP wars is when the gas to feed the extra HP cost more per unit than stock. Or anytime you get less MPG than stock.

    I remember reading some place that the dauntless 225 flywheel weighed between 75 and 100 lbs.

    Hmm, I have to jump in here. Way back when, I had a '64' CJ-5 with the F head engine. About once a month, south of Las Cruces a lot of us would get together for a fun hill climb. We had an arroyo that had sides that took a fairly good driver to get up. Some really good drivers could get up with a little momentum left, but most of us just barely made it, if at all. Many the times I came down backward!

    Then came the V6 model. With the added horse power and heavy flywheels, the CJ-5s would occasionally go over the top and take two or even four wheels off the ground, they were going so fast.

    Of course I had to have one.

    My 64 with an added overdrive would get about 13 mpg on a good day. As our altitude was around 4000 ft, after my V6 was broken in I changed the carburetor jets and routinely got about 20 mpg.

    Because of the huge difference in the differential ratios, the V6 went faster, got better mileage and climbed hills a great deal better.

    In fact, the ONLY downside of the V6 that I ever saw was that when you changed the oil, the oil filter oil dripped on the front differential. No big deal considering the advantages of the new power plant.

    My opinion only, but me and this Jeep have been wheeling for 44 years come August. I never once looked back.

    obviously in something as lite as a jeep horsepower and diminshing returns is something to consider after all they put four bangers in em and made most of the roads in the country my 225 has plenty of power for anything Wyoming has had to offer and wont break things if I punch it a liitle but......what makes you grin. gotta like what you drive if you want more horses then get em.
