    Fusing two engines (welding)

    DOHC's stated desire to build a "Honda V8" remined me of this post I read on www.speedtalk.com. Larry is the real deal so I have no doubt that it's true. See his website for information about him, his company, and it's relationship with Honda, www.theoldone.com. Larry is the most tight lipped...

    E85 = accelerated piston and ring wear?

    Thanks for your thoughts, all is appreciated. I was scanning through a maintainence schedule for a 2005 Ford F150 yesterday and noted that oil changes for any vehicles using E85 more than 50% of the time were on the shortest schedule. I changed the oil in my truck a last week and it looked...

    PGMFI Clear Flood operation?

    Usually until the throttle is released. If the engine drys out enough to start combusting the first thing people do is take their foot off the throttle. Vernon

    E85 = accelerated piston and ring wear?

    This was posted on a forum I frequent: "The company I work for makes the low friction coating for the piston skirts of all GM and Ford pistons. And no, there is no teflon in the formulation. I have been working with the piston manufacturers on a new coating formulation when one of the lead...

    prevent sludge in 2.7 engine

    Dicer, if you look around you'll see the oil industry and most people are refering to the light tar like coating on internal engine parts as sludge. It's coking in a classic sence on the hottest parts but it also breaks down the oil and free floating coked oil gathers and builds up everywhere...

    prevent sludge in 2.7 engine

    The Chrysler 2.7 engine causes the oil to break down because of excessivly hot surfaces around exhaust passages that the oil travels on. The PCV has little to do with it in this case. I've worked on three in this regard, two had already sludged up and had rod bearing failures and one was...

    Boost leak in turbo? Any suggestions?

    Quote: "Stock cams have only a few degrees of overlap, especially on 4 valve engines designed for fuel efficiency, but anything made in the last 80 years has some overlap." With a mechanical valve train maybe, but by the time you get this test set up and start checking most all hydraulic vavle...

    Boost leak in turbo? Any suggestions?

    Here is a post I wrote some years ago decribing this method in detail. Most stock cams don't have overlap and it should work on a Hyundai. Soapy water works better than listening. http://www.sccoa.com/forums/showthread.php?t=19149&highlight=leaks Vernon

    Highest Compression Ratio for E85

    If your question is would a smaller engine built specifically for the advantages of E85 generate better fuel efficiency than a larger one built as a gasoline engine but burning E85, both generating a peak output of 100 HP, then yes. Most certainly the smaller engine would consume less fuel...
