A lot of heads with 32mm intake valves can't flow over 90cfm on our test bench. Big valve doesn't always mean big airflow.

Our Level II moves 100cfm with over 110 foot per second faster charge speed than a stock head with a big valve, for a full cylinder at higher RPMs. That's how horsepower is made, and it's also why we don't use little baby 24mm carburetors.

Come get real power from us and leave the competition behind!
