Question

Quizplus · Accepted Answer

Technician B is correct because manifolds that only need to flow air can indeed have sharper bends compared to those that must flow both air and fuel, due to the risk of fuel pooling in the bends of the manifold. Restrictor plate racing actually involves limiting the air intake to the engine to reduce power, not blocking off exhaust ports as Technician A suggests.
