Darin,

I was reading the earlier comments in this thread and got the part where you discussing what gears to use to achieve about 1200 rpm at 55 mph, if I recall correctly.

So I used one of the ScanGauge channels to show rpm, and in the Insight this turns out to be 1200 rpm at 35 mph.

Now in the summer, this creates a very easy load for the engine, but in winter driving it is close to the bottom rpm I can run without the engine "throbbing" from the 3 cylinder engine pulses.

I guess I am wondering out loud if you could actually drive the car with a wind load at 55 mph and still maintain this engine rpm?

Seems pretty low to me.

Jim.

It is low, and to be honest, I was probably just thinking out loud when I posted that.

This thread has turned into a bit of a monster and the unfortunate thing is: while I did actually start on having a custom set of gears made, I never finished the project.

Proceeding further isn't on the radar since the Firefly was relegated to "backup vehicle" status after I got the Insight. It's not even on the back burner... it's right off the stove!
