The torque pipe in question is sold by a crook by the name of Osama Bin Denny. It is a pipe that is comprised by a inlet pipe welded to a Y fitting--two straight pieces--welded into another Y fitting--followed by an exhaust outlet. I'm guessing that it may be a spin off from V-8 exhaust designs that looked to maintain exhaust velocity.

My opinion would be to apply your money somewhere else. You probably wouldn't see that much of hp gain if any at all. I'd spend the money on something else. I'd think a 4,6 or 8 cylinder motor would benefit more.

That sounds about as good as his 95+hp without stroking the tractor. Of course that is with his "other" goodies. LOL

I reckon we need to open up a "Bernie's Carb Shop" with some rip off performance Deere stuff. Just to make everything equal. Just joshing burns.

A 4 cylinder 4 stroke idustrial/agricultural engine is known to be about 35 to 36% efficient maximum. The fine print of his ads say bores up to
4.310. The Farmall with a 4.310 bore X 5.25 stroke would yield 307 cubic inches. 307 X .36=110.52 flywheel horsepower, assuming optimum cam and ingnition timing and also factor in better intake/exhaust manifold and carburator and use the ASAE 86% rule would yield exactly 95 PTO horsepower. I'm to not a fan of Denny's but the Arias piston design looks about exactly what I designed, and the piston manufactuers are quoting me prices in the $120 to $130 each range. A flat top piston drops this engine's efficiency down to the 24 to 25% efficiency range

Agco Puller-

These calculations suggest that this combination SHOULD produce that kind of power, but it cannot!

If a 307 cubic inch M could make 95 HP with just different pistons and cam, there would be people lined up at D_nny's clear back to Dayton!

Since you brought up the ad for discussion, I would like to note that the ad does not say at what RPM this "95HP" was demonstrated.

The reality also is that if D_nny's magic pistons (as they have been dubbed by others) did what is claimed, there would be people on this board defending this combination. I have yet to see that....

Regards,

Goldsburg

I must be missing something. Your calculation will only work if you making the coorelation of 1 cubic inch being equal to 1 hp.(Not in this case) Denny also sells the 350 cubic inch kit with Arias pistons and 6" stroker crank. According to your method of calculation this would only yield 108hp. He is claiming 120???

Don't misunderstand my comments as being directed to you. I think Denny is a crook. I would rather buy the billet crank from Lemmons than buy lies from Denny's.

You gotta admit burns, one of them torque pipes would look mighty handsome on that Burns-o-matic G of yours'. How bout one on the intake to match. Might work like a turbo, but legal for stock. I do want credit for the idea though.

How does somebody give credit to another when everybody thinks you crazy. Because, I would have to be crazy to dial Denny's number. Good talkin to ya. Drop me an email sometime.

Right on burns the formula should read cubic inches times .36 horsepower per cubic inch. And your right on about Denny; his attitude is what kills me he knows everything and you the potential customer don't know jack!!! Ask him some technical question and he wants to go off on you. At Denny's the customer is always wrong. I'm sure the rod ratio falls off on the 6" stroke kit. I would guess about 105 would be about
max on that kit.

Please tell me why I have a different opinion. I have dealt with them on no less than ten occasions. Every time I have called I have been able to speak with Denny. I have just picked his brain sometimes and other times I have purchased product from him. I have not been disapointed with his products. I won't say that I coudn't have bought the products cheeper somewhere else. One caveat to this is we don't have a rpm limit so I can make 95+ horespower at 3500 rpm. It is really stock except for the cam which is a low rpm cam and the electronic ignition and distributor.

Nobody here has come foward with any specifics on why he is a "crook" other than conjecture. I think it is a shame to destroy someones reputation from behind a computer screen with no hard facts or examples. There are many people who read this that never post and there desisions will be influenced by the "experts" on this forum. I think it makes fun typing but has real consequences to real people.

Local guy bought a performance camshaft, govenor and carb for his M. Installed all of the parts on the tractor and ran like crap and lost around 10-12 hp. I realize there can be some human error involved but here is what he found.

Camshaft, base line radius on the different lobes were inconsistant. Cause worn cam. He shipped an old camshaft and when he asked for an exchange from Denny's. He got a polite F-You and the accusation that the owner switched cams. $200 lost

Carb, the owner scribed his name into the carb to be sure it was his own. Upon closer inspection, found that only the choke plate was removed and most of the gaskets were reused. Cost $260

Govenor, the maximum rpm he could get out of the "performance" governor was 1900rpm. All it was a stock govenor. $225 lost

BSB, I'm glad that you have been fortunate to receive good parts but there are a lot of good folks who have not.

BTW, another puller in the are got screwed by him over an electronic ignition. But thats another story for another day. It doesn't take an expert to be screwed over by a less than honest business.
