if this technology was good for diesels we would have seen it in offerings from detroit, cummins or cat.
I don't think this theory would apply to a diesel at all. Just gas engines. So, why the question on a diesel forum? Just because of the level of intellect floating around here.
 Also, I know of a few horsepower junkies posting here. So Bob, do you believe the grooves would improve performance in say, a 500 inch twin turbo Caddy engine? Assuming, of course, that you could get traction even without the grooves. ;D

Thanks Bob. Lets suppose that combustion chamber size, and subsequently static compression, would remain the same as before the groove modification, by performing a minimal surface milling of the head.

No idea how this can be aplied to diesel.....
I'm not thinking that it can. The topic was intended to initiate a dialog of opinions about these theories. They are being applied, so far, to 2 & 4 stroke gasoline engines. There are some very knowledgeable folks posting regularly on this forum. Conversely, there are some not so knowledgeable folks posting as well. I would like to get opinions from EVERYONE here. I am not concerned with quantification, just opinion. Come on guys, if this were a negative thread with mud slinging it would have pages of replies by now. So, out with it...........

Sounds like 2 thumbs down so far. Anyone else?

Is anyone hear familiar with Somender Singh? I am curious as to how some of you, especially Guy Fawkes and Mobile Bob, feel about his work. This is open to anyone with an opinion, good or bad. So, let's have it.

Quinn, I hot tank my own stuff at home with the following method:  Arrange 3 cinder blocks under a steel 55 gallon drum in a triangular fashion, with only a couple of inches from each block under the barrel. Place all of the parts to be cleaned in the drum and fill with water to 4 or 5 inches above the parts. Add 2 bottles of Red Devil Drain Opener carefully, wearing eye protection (can cause permanant eye injury). Start a fire under the barrel using anything from charcoal to old pallets to just plain firewood. Build the fire around the barrel and keep fed and burning for 4 or 5 hours. This makes any ferrous alloy look brand new whether it's a cast iron engine block or a set of steel vehicle wheels. Again, this is what works for me. This has the potential to be dangerous simply because of the open fire. I don't want to be held liable for anyone that lacks the common sense to do this safely.

If a cam lobe is not hitting a tappet correctly the chances are the timing gear is off by the same amount.
Thanks, Hotater. That stands to reason.

To reset camshaft position you may only need to turn the collar around that holds it in place.
Could this cause any cam gear alignment issues?

Doug, you sound alot like me. Same qualities, most good, some could use improvement. ALWAYS willing to reward effort. Chances are "The Claw" will do one of two things. He'll either let all of the ridicule fuel his determination to succeed. And based on your observations of his drive and work habits, this is what will happen. Or......... he will let the torments build up inside and one day "GO POSTAL" with an AK-47 seeking revenge on anyone who had a laugh at his expense. Nature has a way of working things out. You can rest assured that you had a positive impact on that kid, and he will probably never forget you or even what size and brand of tire he patched for you. You did the right thing.

The heavier flywheels on his engine are a dead give away that it is not a 6/1. binnie
Thanks binnie. I'm learning a lot today! Heavy they are, indeed. Somewhere around 200 lbs. apiece. Watch your toes when pullin' em' off. :o

My aplogies to the OP for the hijack.
The cold start valve is perfect for my application as I plan to turbocharge a 6/1
Darren, I commend your ambition, man, I really do. However, turbos typically don't work well, if at all, on single cylinder engines, especially at slow speeds. Turbos even have a lot of difficulty on twins. The problem is the infrequent exhaust pulses. Turbos work best with many frequent pulses. A 12 cylinder engine at 10,000 rpm would be much more ideal than a single cylinder engine at 650 rpm. That's an extreme example, but it illustrates my point. A supercharger doesn't care about exhaust pulses and may be a more feasible way to get the boost that you're after. Something to consider.

Thanks Firefly. Maybe the lifters will have to ground before they rotate. I have not seen them myself. I don't know how bad they may or may not be.

Can anyone tell me how to use the insert image button?
Just copy your picture link to your clipboard. Select the "insert image" icon above the smileys (second from left). Place your cursor between the two sets of brackets and paste your link from your clipboard.

Thanks, bitsnpieces. Does that mean that externally they appear identical? This would explain Procrustes confusion.

Very nice work Hotater. Did you buy your Artesian well in Artesia?  ;D  Sorry, couldn't help myself.

I put a brass or bronze thrust washer at the red dot. I did it mainly to get my IP lobe centered over the roller. It also reduced the lateral play to about .010" and gave a little more offset on the lifters.

Thanks Geno. A picture is worth a thousand words. Man, your cam thrust measurment must have been huge. I'll run this idea by Pops and see if he'll go for it.
