    Low Compression/High Boost and Pump Gas

    I am of the opinion that each engine is different as to what is doable. Two engines that appear to be the same will accept different amounts of boost. I can only relate what has worked well for me. I built my 340 eleven years ago and this spring was the first time I had any problems. I pushed...

    Side By Sides, UTV's, Whatever They Are Called

    I have a 2013 CFMOTO Snyper 600 SxS. It has about 7500 miles on it and I just finished rebuilding the engine. Haven't even got the body back together yet. I bought it in 2015 at an auction and the wife and I used it a fair bit. Time to sell it now though as the wife doesn't want to go anymore. I...

    Arriving at the 2024 Atlantic Nationals in Moncton,NB

    @jimjimjimmy in his 70 Duster and me in my 72 Demon coming in the entrance to Centennial Park on Sunday. Unfortunately I couldn't find a photo of @leblanc and his 76 Dart Sport. We spent the whole weekend rain or shine at the park having a great time as usual. Jack

    Outstanding Actor Donald Sutherland gone at 88

    Great actor from my hometown. Thought one of his best roles was "Oddball" in Kellys Heroes. Strange there has not been much on the story in the local news. Jack

    Picked up the new ECU yesterday. Will put it in and do a couple of other housekeeping jobs on the car as well. Then it is get ready for the Atlantic Nationals in Moncton, NB. Jack

    Don't have to worry about that one. I don't use the timing control on the FiTech. Jack

    Ailing engine (Updated after teardown)

    Yes. I am using my original one right now, the only problem with it is I can't use the handheld to change my tune up. I have no idea what happened to the second one which was only 10 months old when it died. It was working perfect until I took the top of the engine off to replace the head...

    Ailing engine (Updated after teardown)

    I just heard back from FiTech. They hooked up the ECU to the testing equipment and it failed and needs to be replaced. Now the good news, they approved it as a warranty item and a new one is already on it's way to me. Should be here next week. Jack

    Took it for a shakedown run of a few miles today. All seems well. I'll know more after a few more miles. Who knows with the Fitech. I will be calling them tomorrow as it was still under warranty. Jack

    Ailing engine (Updated after teardown)

    Life finally got out of the way and I was able to put the engine back together today. Everything went well until I went to start it up. I have no idea how it happened but the ECU on my Fitech system decided it was time to pack it in. Absolutely not power to it. All fuses were good so I don't...

    I have a Champion 3 core aluminum radiator. I believe the width and height are the same as a stock 340 radiator. I have a very narrow flex fan and no shroud, no room for a shroud. My fan is only about 3/4 of an inch from the radiator. Close, but not touching. I ran an electric fan system at...

    Ailing engine (Updated after teardown)

    I am running a FiTech EFI dual 4 setup and control the fuel with it. At idle my afr is 14 to 1. At cruise not under boost I go to 13 to 1. When under boost it is 11 to 1. This is a pretty rich setup that helps to cool everything down. I also run my temps at 156 degrees. The only time it goes...

    Ailing engine (Updated after teardown)

    I started out at 28 degrees. I slowly upped 1 degree at a time to the 31 degrees. I even drove it trying to get a ping out of it and never did. The engine just seems happiest at 31 degrees. I even upped the boost to 12 lbs once and got on it for a couple of short bursts. The only thing that did...

    Ailing engine (Updated after teardown)

    The retorquing is something I was thinking of doing not what I have done in the past. A straight edge goes on it tomorrow, I didn't get a chance to look at it today. Life got in the way. I did put 5 gallons of fresh gas in before I started it in April. I did start it a couple of times during...

    Ailing engine (Updated after teardown)

    None of the plugs were damaged. One was fouled a little. I run my fuel mixture a little on the rich side to start with and that is what 7 of the plugs showed. It was just #6 that was fouled and that was the one that the gasket showed as the worst. Jack

    Ailing engine (Updated after teardown)

    After lots of thought I have decided what I am going to do. I decide to go with the Fel Pro 1008 gaskets again. Reasons for this. I can get them locally, they lasted 11 years the first time, I do not have to remove the engine to have it resurfaced. That's a big one. Don't have to have the heads...

    Ailing engine (Updated after teardown)

    There is something else that I failed to mention for some reason. I think it is important in this discussion. When I was loosening the head bolts on both sides I could not believe how easy it was to turn some of them. I am used to really having to reef on the strongbar to loosen head bolts. Some...

    Ailing engine (Updated after teardown)

    I don't pull any timing. I have my timing locked at 31 degrees. It seems to work well for this engine. Remember it has been together for 11 years and about 1500 miles per year. And I drive it, not baby it, just ask the wife. lol Jack

    Most of the time I am right at 9 lbs of boost when I get on it. Jack

    Ailing engine (Updated after teardown)

    I just came back in from taking the drivers side head off. It was pretty much the same story as the passenger side, just not as bad. It looks like I am going to get out of this with just some gaskets. I did check into what my pressures should be and it looks like with an 8.2 to 1 engine like I...

    Strange, I go to Summit and they all say special order. Mancini and Jegs have them as well though. Jack

    I was just checking out the cometics. There is a 4 week wait at minimum. That's nuts. I wonder what other options there are? Jack

    Ailing engine (Updated after teardown)

    I'm guessing a little bit of oil was getting in from the lifter valley. There was light blue in the exhaust but not a lot like you would get with rings being worn out. I don't know what the cylinder pressure should be in an 8 to 1 compression engine, but what I am thinking might be a...
