Re: horsepower vs front shock settings
Ah sorry for the misunderstanding. Viking says to do it when the car is being trailered, so we have been. Just thinking out loud. If that sets the shocks to maximum stiffness, or closer to 50/50 than 90/10, I wonder if that is to reduce the amount of bounce the car experiences going down the road i...

Re: Brake shoe fitment
The shade-tree method I was told (but never tried) back in the mid-70's was to glue a sheet of coarse sandpaper to the inside of the drum with rubber cement, put it all together with tire for a handle, and spin the drum while slowly adjusting the shoes tighter and tighter. I'm sure somewhere there w...

Re: Overbalanced 3.75” SBC crank and vibration
is there a cheap from Amazon style tool that will measure vibration? Know nothing about what's available now but a few years ago a coworker had an app on his old iPad that we used to measure the x, y, and z vibrations on an electric motor before and after we replaced the worn rubber mounts. Numbers...

Re: Why?
No idea why, but take out insurance after you finish composing and before you click send by selecting all and copying. That way if you do have to log in or anything else goes wrong short of a reboot you can just paste the text back in once you are ready. Just don't forget and cut or copy anything el...

Re: 3d printing
An "old fashioned" way would be to glue and fill the crack shut if necessary to get a smooth surface and build up and hand shape any broken teeth with bondo. Then pull a mold using a soft polyurethane rubber and use that to cast a replacement from hard polyurethane plastic. Years ago I dab...

Re: Acquiring Liquid LN2 in Todays World
I know how to store LN2. I have never done it at my shop. I wanted to know about the evaporation rate as the liquid boils off and how that relates to cost. This does not look like a practical solution due to cost and inconvenience. I am considering two other options. Both would provide an emergent ...

New phrase for blowing up an engine
I've heard and read many euphemisms for blowing up an engine but I learned a new one from Scott Manley in his video on the Blue Origins rocket failure today. He zoomed in on the exhaust right before the failure and pointed out a couple of bright flashes and said that they were a sign of an "eng...

Re: Unique Engine – More Power Needed
Carbureted only. One could accomplish the same IR tuning with a pair of the old 3-bbl Webers, but they're hen's teeth and learning to get them right is a too-long process. How long would the runners have to be to effectively have the same isolation and ram tuning on a plenum as an IR setup? With a ...

Re: 13100 rpm fourbanger restricted to 9300 redline
Trying to approach this from a different direction, this may not be useful. Either the engines are actually making 10% different power, or the power is being made but is being lost in one of them. Start with #1. You say the AFR is the same so the fueling is the same, but do you have any way to measu...

Re: cut and sleeve
Don't raise the bridge, lower the water :mrgreen: . If the aluminum is soft enough you could expand the ends of the original tubes a bit. You could test with the piece you cut out, to make sure it won't crack. I used this tool from Amazon: https://www.amazon.com/gp/product/B077RT3D79 picked at rando...
