I'm the first to say I don't know much about head design. So please explain how they will increase water flow by 40% and airflow by 75% in this size casting and have the structure to support boost and drive pressure.
Dumb it down for me please. Just saying it can be done doesn't explain your how they will achieve this.
Airflow is not about size. That is what a lot of people do when CNC porting heads, just take a given amount material off the port walls and call it good. Port design is far more then meets the eye. 400 cfm out of a duramax head is 250 % bigger then stock, and is absolutely possible, and achievable out of the new Edelbrock casting by the time these heads are available to the general public. Notice the dog leg port is straighten out enough to get a tool path in there.
As to water flow , have you ever cut up a set of Duramax heads, I have years ago. the ability to increase water flow is the easy part
Frankenstein racing heads in top of the line. They are primarily a design shop doing work for many manufactures , including OEMs like GM on the CTS V turbo motor.
There are 20 + head programs going on go different manufactures with Prototypes on the flow bench daily.
The other great deal is the process that Edelbrock chose to do production heads, Permanent mold. Their intentions are to sell many thousands of sets a years . That was not possible with the Box method used in the Brodix heads. This means a better , stronger product for half as much.
Ill have a set of the dyno before the end of the year.
