What kind of boost can those engines handle? The K04 can push some crazy numbers cant it?
A factory K04 can push about 20-21PSI which is what I run, stock is 15.6PSI. A ported K04 can do around 24+PSI, which is what I may do to fly under the warranty radar.
People with PROPERLY tuned motors are seeing 24-26PSI on the stock bottom end. There is a race version of the MZR motor pushing 1400HP and at one time held or may still the record 1/4 mile for 4 cylinder drag racing breaking into the 7 second barrier.
