Perhaps I should buy one of those engines from TaylorTradingCo and do a full on build with it. Wish I could find more liner kits. I could feasibly rebuild it "stock" but add on a girdle bottom end, better rod bolts, balance the bottom end, and search for upgraded valve springs. I think 300hp...

If you'll read into his build more, he's done pretty much everything I've mentioned that I was flogged over to get the engine to withstand the abuse. I will say this, I can assure you he has a substantial amount of money in that engine.

Well crap, that didn't post the grid nicely. So here's a image of it:

Use the "+ button in the lower right corner of posts to multi-quote, then hit the reply button. :) There's no way I'd put 20psi of boost routinely to a LDT. Remember these are 22:1 CR engines. Personally I don't take mine over 14psi. 12psi is normal max. I will have to search back though...

This is a broad comment, but increased boost does not equal increased performance. I had to preach this time after time on another diesel performance site when people would brag about the fact they were getting 45+psi out of a HX35. After 35psi, you're just blowing "hot" (any time you compress...

Sorry I haven't been in the thread recently. Specs of all the multifuel engines: LDS 427-2 427 ci,140hp and 350ft/lbs tq LD 465-1 478 ci,125 hp and 305 ft/lbs tq LDT 465-1C/1D 478 ci,130hp and 330 ft/lbs tq LDS 465-1A 478ci,175hp and425 ft/lbs tq LDS 465-2 478ci,195hp and 425 ft/lbs tq...

Did you get your truck Dyno'ed yet? I'm curious to see those numbers.

Hornetfan and I have exchanged a few PMs and worked things out. It was only a misunderstanding that has been resolved. :)

I never stated that YOU didn't address YOUR weak bottom end. I pulled those quotes out of this thread as they were facts I added to this same thread. Again quotes from me that I made in this thread. (Please go back and read/verify yourself) The fact I stated that I owned several of these...

Didn't read back through this thread did you? Everything I quoted came from this very thread. Now for lowering the CR. Lowering the CR would help if you were to increase boost, which is what they mentioned about a better turbo. This is very common practice in diesel performance. Where in...

I never said a rebuild was drastic. I said that 300hp without the other precautions I mentioned would be. I would say that just rebuilding the engine with a balance and blueprinting would certainly help with the longevity of the engine. But you're not going to drastically improve the bottom...

Oh I dunno.... I removed the subjective comments I made. But plenty of facts there.

I guess the facts just get in the way. Best luck.

You're still avoiding the point of you're asking for a power increase of 200%....

No, it was rated at even less power as a diesel tractor engine. And no, it's CR ratio was less. http://www.tractordata.com/farm-tractors/000/7/1/713-oliver-2050.html They only made about 9500 of them BTW. And for two years. The NA Multi has the same CR as well. Some facts to think about...

Because the engine no longer is a pure diesel engine as it was first designed. Everything you're thinking with engines doesn't completely apply here due to mass. These engines weren't meant to rev like the military set them up to. The turbo was an afterthought. Wasn't meant for...

I have ran many of gallons of Jet-A in my cummins, many many many gallons... A stock cummins with a VE or P pump can have anywhere from 150hp to 235hp stock. Which is very detuned. Simply increasing the pumps fueling will get it over 250hp safely.

Correct, but a 12v Cummins can run WMO and WVO just as the multi will. The Multi can run gasoline though. (With oil and you're shortening it's life)

Removing a fairly substantial amount from the bowl would severely affect the hypercycle design. Even the pistons in these engines are large and extremely heavy. Typical stress failures in this engine are from rods, rod bolts, head gaskets, pistons, and piston liners. Also, for what it's...

That doesn't address the weak bottom end at all. Also, milling the bowl would have to be done carefully to avoid loosing the swirl effect the multifuel has.
