sorry for late reply, what is POH?

I have a like new non provison 377 engine, can i buy just the case only and use my 370 crankshaft in this 380 case? you say buy case with a crank but cant i use my 377 crank?

Excerpt below from the EFI system controller from Snow products as I already posted this link but I guess some folks just dont read any of it and geared up to just be nay-sayers ALSO Im using automotive kits for reference only as its OBVIOUSLY too heavy for aircraft application, at least the...

Snow performance has a water injection digital control unit that works with the EFI mapping (ECU) to control the water injection so maybe a good candidate for the EFI version of kohler engine which use Delphi EFI ECU unit. Carb version engines maybe more challenging to install water injection...

there is now kits for not just for boosted engines but now for Naturally aspirated EFI and direct injection engines but dont know if good for carbureted engines?, I did see though a carb spacer with injection nozzles on one companies website so maybe rare but possible to use for carb engine...

I dont think the author meant for external cooling but for internal? Ive never heard of external water injection? or spraying? Im sure its been done but again I think he meant internal injection application.

Ive installed water injection in my supercharger system on my Shelby mustang its a pretty simple system, i also add methanol to the distilled water to increase octane level as well. water injection was invented in WWII for supercharged aircraft to get to higher altitudes. it also cleans...

it may not be even worth importing engines from china on a very small scale like I did (1 each), add shipping, brokerage, customs, warehouse handling, tariffs, taxes fees once arriving at USA port are passing the cost of the engine itself!! and in the end AFTER paying all these fees (well over...

Goakin engines came in three forms, where there was WITH CVT and gear box option, and without CVT and gear box and now its only an INTEGRATED CVT and gear box option, no longer able to remove CVT and gearbox, here are photos of comparison of the three. they seem to discontinue snowmobile version...

attached photo of what belt drives air trikes sells, but mostly for rotax engines and few others?, but nothing for industrial briggs/kohler engine or goakin engine. air trikes specialty is gear drives and can tailor to your needs in that regards, but again Ace aviation is making belt drives...

nd this is the best explanation yet to date, THANK YOU, and in laymens terms as it should be IMO thank you again, I contacted valley eng. to see if they would be interested in selling the design or something and not let this clever design die, if not then we need to reverse engineer one, who...

looks like gaokin engines restructuring their product line and obsoleted the 800cc and other sizes for WITHOUT CVT and gearbox option(snowmobile version). looks like only available now are WITH CVT and gearbox(motorcycle/UTV version) which will not work in aircraft application, i believe all...

RE: Valley Engineering Belt Drive So the balls can dampen in both directions? where a spring steel torsion spring can only dampen in one direction? I'm trying to figure out what advantage the rubber balls have over a torsion spring? in this case?
