Hi guys,
i am after some performance tips that anybody can give me in regards to getting my Lanz Bulldog tractor to go a lot better in tractor pulls, some spec's are 10.25 litre cap, piston 227 Dia with a 260mm stroke, is a 2 stroke engine with the piston running horizontal, rpm is around the 700 mark, is hot bulb ignition with fuel being injected by atomiser, normaly run on crude oil but can be run on diesel with no problem, crankcase is only sealed with felt seals so pressurizing the crankcase too much is a problem, the compression ratio is only 5:1 and is very slow burning, also the piston weighs about 50 lb's, so i hope someone can give me some ideas, ie will nitros injection work?, or maybe some methanol in the fuel, water injection?, many thanks colin

 

I am not sure about performance modifications on those tractors, but I was always fascinated with them having one large horizontal cylinder/piston, and the amount of torque they produced. They are very rare here, I have only ever seen one in person.

 

Excuse me to say that- these tractors are very rare and well protected collectors items in germany (land of origin) Why do you want to kill a piece of history? Man, 1938 (!) This is a piece before the second WW started.
Ever thought about selling with profit to an collector?
