This is not the first time I have heard this suggestion recently. Sidevalve engines are much simpler and cheaper to build than modern OHC engines. They are also much more compact so can give lower engine bays and more design flexibility. Materials and fuels have come a long way since sidevalves...
I never thanked you for that excellent link Kai. Thanks! If I put the EFI on the A engine I'll probably grind a custom cam so that I can use the exhaust ports for inlet to get around this problem with simple batch injection. How big can the 1275 "A" exhaust valves go? I could never...
Just some ideas and observations. How about floating the vees or roller blocks on air (most workshops have a compressor.) Both underneath and end float can be air. The machine I worked with some years ago locked down the bearing blocks until the machine was up to speed (to save the sensors from...
Thanks for the test info Marquis. I guess my guess was wrong!
A lot of pre-1910 cars had twin plugs. The big 1909 Benz that I helped get running again for my wedding in Sweden 18 months ago had twin plugs (half on trembler coil half on magneto.) I know some early US cars like the 1907 Stearns...
Hi Neil,
If I understand your question correctly, you'd like to know if the longer dwell time due to the longer rod/stroke ratio will give the usual combustion advantages even in cases where domed pistons interfere with the combustion efficiency. My guess would be that combustion would still be...
Hi all,
I recently found this list while doing some research for someone who has some flash gasification patents. I can’t believe how much I have learned— thanks.
Firstly, in line with what several of you have said, the biggest mistake I have seen in building high performance engines (usually...
