headwork aka port & polishing info
for the next project on my bike i have enlisted friend and head porting wizard Bill Deshong that owns Port-tech. our plan is to improve the exhaust side of the port and clean up the intake. after receiving the head Bill was very impressed with the way the factory designed the head. he took some flow data to see how it flowed stock and afterwords. i will try to tear the bike down in the next few weeks to install and tune as i purchased a used head to perform this on. as most know my current bike has bolt on parts and has made 200hp sae and 205hp std with vp mr12. with this current stock setup it has won the Brute Horsepower shootout 2 years in a row. i already know for a fact by decking the head and adjusting cam timing these bike pick up 10hp. we feel that by porting and decking the head we should be in the 215-220hp range once completed with mr12. this will be done with stock cams as i feel most wont spend the additional $2200 for the 5-7hp it will create.
once this project is completed i plan to have Bill port my factory head the same way to sell. i can work this on a exchange basis or it can be purchased outright. please pm me if you are interested in having this done or have interest in my other ported head. i will update this thread with dyno charts and pictures once completed.
port-tech has been building some of the fastest dragbike and lsr engines around. Mark Dotson that just won the shootout at the willmington mile had one of Bills motors installed.
please leave your feedback and i will answer the questions you might have..
