Go Engle 100
I have a 1950 ccm with Engle 100, stock 1600 heads, 9,5:1 C/R
Put`s out 108hp / 186Nm
Strong as an ox right where I want it:
Or choose type 4.
This is the dyno of my 1971ccm with 280 degree (0 lift) webcam 494 (it is advertised at 288 degrees and 0.465"lift. But it is really 280 degrees and 0.435" lift at the valve), stock heads (914), 9.1:1 C/R.
The torque just stays flat up through the revs! 136hp/185nm
Runs 150 hm/h all day without overheating (90 degree oiltemp), and you can build it so it looks almost like a type1 engine (last pic shows engine in my car), but the cool temperatures is what really impressed me when going the type4 route, and in a bus that probably wont harm anything.
The handdrawn one is the corrected hp/nm on the engine, and the computer dynoprints are on the wheels.
