Getting back to getting more performance out of (souping up) the LDT:
As someone that has put a lot of thought into this subject and ended up taking the LDS swap-out route I have to agree somewhat with the poster that said something to the effect that trying to soup up the LDT is like gold plating a t%rd.
It's not that the LDT is a substandard engine it's just that (IMHO) you can't get a LOT of SAFE LONG TERM performance out of it without spending a lot of money on the project. Once again --- IMHO --- you need the oil cooled pistons to safely push this engine very hard for very long. This is the secret of the LDS's success. Unfortunately, pistons are about as far into an engine as you can get. I also believe the cam is diferent in the LDS. The lDS sure sounds different.
As fun as it is to dream about all the neat tricks that can be performed to get better preformance, unless you own your own engine shop they all cost money.
Considering that the deuce is and always will be, I feel the LDS route is the way to go. Having said this, I have to admit that Mudguppy's Cummins mod has me drooling in lust
.
On the other hand I'm told a set of injectors for a Cumming runs close to $4,000.00 "Ouch"
NOW --- Let's throw rational out the window and brainstorm some fun stuff --- like doing some weird preverted things to an LDT. If I had a strong LDT to play with here is what I'd do.
First, I'd buy a pyro and boost gauge. Second, I'd take an oath that I'd religiously watch both of them. Third, I'd either liberally dose the fuel tank with lots of Marvels Mystery Oil or, better yet, switch over to a heavy blend of 100% filtered used motor oil. Forth, (here is where it gets fun), I'd start dosing with propane.
I've always felt there was a lot safe performance that could be had for very little money by dosing with propane. There are ready made kits out there that can be had but IMHO that takes away from the fun.
I've read that the performance is better if propane is injected (dosed) pre-turbo. The reason being that the turbo serves to mix the propane with air. I've also been told this can be dangerous because should the propane ignite in the manifold it could blow up the turbo.
I'd install orifice injection receivers both pre and post turbo and experiment with both, one at a time naturally. I'd start with small orifices to see how it effected performance.
At one time I planned to install something similar to a two-speed alxe button on the gear shift. To turn on the propane pull up on the button to shut it off, push down. Once above say 1,800 RPM you could activate the propane when climbing a hill (or passing a Greyhound Bus
). A simple manual system with a picket full of different sized orifices for experimentation could get the system off the ground. Later SS members with more smarts that I have could refine and automate the system.
I'm told propane is a drying fuel thus the liberal dosing of Marvels Mystery Oil or conversion to filtered waste motor oil. I'm also told propane is a cool burning fuel therefore thee "might" not be a heat problem. If there was a water injection system could also run parallel with the propane system. I personally wouldn't install the water system until I learned that it was indeed needed. Simpliity is king.
Sorry for accidently hijacking this thread earlier. Hopefully this will get things back on track.
