Excellent win Darren. That Dinan V10 is really something.
I'll have to agree with the statement that dyno numbers do not represent the real world. This is especially true when only peak figures are generally discussed.
Overall power output across the usable RPM range (when drag racing - whatever the engine operates in most - probably 6000 to 8250 for our S85's), gearing, and airflow to the motor all play a huge part in the acceleration of a car.
I can say with confidence that our mighty V10's will lose significant power without air being actively flowed in. Even though the design of our air intakes are not true ram air, they must contribute somewhat to providing a decent amount of airflow to the engine once the car is moving.
