Radial engine car

This is the Lemons version of the "Zamboni" loophole. Looks like somebody is taking advantage of it!

wow is all i can say.....

That Jacobs radial won't last a mile. Too many quirks in an airplane, let alone in a car. Neat, but a waste of an engine.

do they give an award for most impressive blow up?

That

Is

AWESOME!

Just FYI: If that motor runs (or even turns), it's worth a fair amount in the aviation area. I'd put it up for sale in Trade-A-Plane and buy a regular engine with the profit.

I guess it's safe to say that there aren't any prefab parts available for that particular engine swap.

Oh...I wouldn't rule that out until you've had a very thorough look through a JC Whitney Catalogue.

Isn't it a Kinner and not a shakey Jake?

I don't know why, call me crazy, but I so want a radial engined airplane.

He said at some point that the motor turns over easily and has compression. One pic shows 'Kinner' on an engine casting.

The crazy part is all the changing directions and speeds that the power output is taking. Since this motor only turns something like 2000 RPM, he's using a ~2.67:1 reduction box to step the RPM up at the transmission input shaft. The two lower cylinders 'straddle' the transmission.

I really really really really hope that they get it going. That is utterly fantastic. If I was gay...

oops, I got my "radial" and "rotary" engines mixed up in my head. I thought this was one of the WW I style rotaries where the cylinders spin around the crankshaft... oy. in that case, this looks almost sensible...

that car is terrifying. not quite as ambitious as the M14c powered gogomobil that came out of Germany a few months ago, but still damned impressive and if they get it running and keep it from overheating every other minute and manage to drive it well, I wouldn't be surprised if it either wins or comes close to winning it.

Wait, I digress, its the Kinners that have the problems in spades.

Um, I'm pretty sure that old of a radial will need leaded gas...

edit, he states since it has valve seats it doesn't need leaded gas, but that's not the only reason to run it, hope he knows that, especially when the temps get high...

Those engines run on 80 octane fuel. If he has the proper valve seats 87 octane unleaded will be fine. It is a common conversion on aircraft.

forgot about the low octane rating once upon a long time ago

I just want to know how he is going to keep those lower cylinders cool..

There is actually too much lead in 100LL for most of the old low compression engines. They will foul the plugs. I have found the specs on the Kinner R-5. It has some low compression. I also wonder how that engine will respond to the continous changes in power. Aircraft tend to run at a constant load.

Dude addresses the fuel issue on the second page of the LeMons thread, apparently that engine has valve seats and does not require leaded fuel.

So much awesome happening, 160hp and 600 lb ft of torque. Makes diesel engines look gutless and rev happy.

not only that, but given the speed and clean airstream, it'll be a trick to keep it cool.

I also want to know how to drive it, maybe floor it while braking into a corner so it'll be revving enough to power out of the corner?
