aerohead,
let me put this project into context.
i am bored with 5% here and 5% there.
iam more interested in the outside limits. i have extra engines some of which have dead cylinders. So i am starting with a 1.6L diesel, 52 hp, 71Lb-ft. I am taking out #2 & #3 pistons and cam followers. Cutting off the big ends of the rods, taking out the clearance and clamping them soild on the crank. Then measuring the unused injection pulses from 2 and 3 for mpg info. see post#34
My limit of acceptable performance presently is 60 Lbs per Lb-ft of torque.
I arrived at that number like this 80,000 Lbs./1300 Lb-ft = 61 Lbs per Lb-ft
My car is 2100Lbs/60Lbs/Lb-ft= 35 Lb-ft of torque minimum.
The 0.8L diesel will have approx. 35 Lb-ft I am taking almost half the friction out of the engine. And I now have an aircleaner, exhaust, water pump, oil pump and radiator designed for 52Hp but i am only putting 26Hp through it. So i can run full rack for hours if i want to, without overheating.
