la case

[jerry m 3]

was thinking of turbo charging my la case it is a 1951 in good shape what do you think jerry

I don't know if it would do any good or not. Are you looking for power or a novelty? My LA is about 75hp with an overbore kit and propane head.

it will work, do your homework and match the turbo to the engine, I would draw through the carb and not blow through it, or find a throttle body injection set up and adapt it

While we are on the topic of LA engines, can the kerosine/gas
head be modified to give higher compression?

I have seen suggestions for using LP gas heads, but I have never
seen one here in Australia. All LAs are getting rare here.

Also, what are good sleeves and pistons to use to get more
power out of the LA without spending hugh dollars?

There is some tractor pulling here, but not a big sport as in USA.
Just wondering what it would take to make up a competitive LA

the problem with blowing through a gas carb is that the fuel pressure is directly linked to boost, Mel could explain this better but as boost increases you need more fuel pressure and it becomes a viscious cycle unless you put the carb in a pressurized box, an lp carb doesn't have a needle and seat so it isn't an issue with lp

Bob, Some guys around here put 5 1/8 pistons in La's for pulling for a cheap build and they ran pretty good, I believe they were Cummins pistons. The compression will come up with increased displacement. There are some good cam grinders in the US that would accent the bigger displacement. The lp head is supposed to be about the best flowing head for the La tractors.

I have an LP head on mine with M&W's and she rolls right along with a 5 bottom or 16' disk. The thing is absolutely fricken loud though!

Thanks Doug.
