Re: A question for all you DSMers

There's a lot of things that come into play...you can think of boost gauge reading as air that is not getting into the motor also. A stock head for example can't flow as much air as a well ported one, so...say all things remain the same but port the head, your boost reading may have been say 20 but now it's only 18.. boost reading goes down but HP goes up as more air is getting into the motor.


Also with high boost levels on a small turbo the turbo will be out of it's flow map and the booseted air will be heated up equaling less true air flow into the motor due to the density of the compressed air being lower.

FWIW A 14b can run up to about a max of 25 PSI on a mildly modded motor.
