You ever figure out the compression ratio for this setup and check the final squish clearances I would like to get this all figured out?
I have a few FL350 cylinders I would like to hoserize by removing material off the top of the cylinder (decking) so I can tighten up the squish clearance on a stock head and slightly raise the static compression to boost performance, this with a reshaped and wider exhaust port should bring up the fun factor, better throttle response, more HP and torque from bottom to top and work well from all stock to a Odyssey with a bigger carb, after market pipe and drive clutch, noticeable gains everywhere.
Since I will be adding more heat to the
Engine because of the increase in power (more power more heat) especially when going to a after market drive clutch where the RPM's are increased I want to liquid cool the cylinder something like done in the pics below.
Also need to figure out a affordable or cost efficient way to liquid cool the stock head have you given any thoughts to this?
One thing I noticed and found really interesting was during my project FL350
http://www.pilotodyssey.com/PO/viewtopic.php?f=5&t=10537 first few heat cycles while checking for the Engine heat I noticed I could hold my hand on the outside edges or top of the head but could NOT hold my hand on the cylinder above the exhaust port to the top of the cylinder, the cylinder heats up hotter much faster than the head, with more surface area on the cylinder wall than the head heat is transferring faster to the cylinder than the head, SO I am thinking modify a cylinder as described above, install it on a Odyssey with the stock head, use a Banshee radiator to cool the cylinder jacket by thermosyphon (no water pump) and no fan on the radiator, take it out run the shit out of it see if it over heats.
Over heat = feel any noticeable loss of power, usually the first noticed is the throttle response is not a sharp or crisp as it was when you first started running it hard, throttle response will diminish or flatten out almost like it is when the Engine is cold and you first take off running it hard trying to get the Engine cleaned out and up to full operating temps, after you feel a loss in throttle response comes a power loss over all you feel the Engine has less power, for example you find a big long tall hill and you repeatedly keep climbing it as the Engine gets close to running hot or over heating you notice it does not climb the same hill as fast almost feels lazier than past runs. The great thing about liquid cooling is you have a little bit of a reservoir that can absorb excess heat and carry it away from the heat source great for when your repeatedly climbing the tall hill as I gave in the example above or something similar.
Thoughts on any of this?
