S-G Okrasa / Solex 40PII Intake Manifolds

S-G Okrasa / Solex 40PII Intake Manifolds
for 25HP / 36HP engines
The ultimate step to power-up Your Okrasa TS, TSV or TSV RS High-Performance engine: Two Solex PII twin-choke carbs on S-G Intake Manifolds. These precisely machined Cast Aluminium manifolds fit both 25HP and 36HP Okrasa cylinder heads.
The Intake Manifolds are machined to take Solex 40PII carbs, but the manifold-flange can be drilled to take Weber 36IDF, 40IDF or even 44IDF type carbs too. Using these intake manifolds, the Okrasa engine will benefit by the separated intake ducts eliminating “lean suction” and cross-effects between the cylinders during intake stroke. The strongly narrowing intake paths furthermore accelerate the mixture and thus create a strong “forced induction” effect which will improve cylinder-filling.
Of course it will need some experiments to find the best synergy of compression ratio and valve timing.
We did not yet dynamometer-runs with our test engine but hope to perform tests soon, we then will bring an update concerning this point.
