The stroke simply doesn’t go high enough on the “Small” engine setting, and not low enough on the “medium” setting
I was trying to simulate the Fiat FIRE 1242cc unit that powers my Mk2 KA :T
1242 cc (1.2 L) - 70.8 mm bore x 78.9 mm stroke
Only goes up to 76mm stroke for 1197cc. And only puts out 63.6hp… Almost there! Target was 69. :T
Definately impressed so far. Gonna preorder come payday.
