Editors note Larry Meaux has been quietly porting heads and building championship winning race engines for more than three decades. A long list of winning customers is testament to his porting and engine design skills. He is passionate about race engine performance and leaves no stone unturned when investigating and testing new theories. In this interview he has devoted considerable time to answering our questions and sharing valuable knowledge that will help other racers and engine builders. Be sure to read the entire interview. Wwe Extreme Rules 2012 Matches Videos. Its long, but Larry shares some great porting tips that you can apply at home. In our opinion any engine you might contemplate should be modeled in his Pipe. Max program to determine optimum lengths and cross sections for intake and exhaust flow paths. Get a copy of Pipe. Max and join the forum on Larrys web site www. Larrys years of experience have made him a valuable resource for engine builders seeking to optimize power and torque in racing engines. Now hes willing to share it with you.

HRET Now that there are so many good CNC ported heads on the market, how much can they be improved by a knowledgeable head porter and is hand porting still a viable option LM Years ago when CNC ported heads first became popular Im sure there were many head porters like myself that thought our future looked bleak, but now there are so many more new head porters as well as many new shops specializing in CNCing heads it appears we can coexist profitably together. Cylinder Heads are still a casting, which can have some core shift or mold setup irregularities. Ive seen CNCd heads where there are areas inside some of the ports that were not touched by the CNC cutter. Some of this depends on the casting accuracy and some of the errors depend on the person setting up the head in the CNC fixture and of course the accuracy of the fixture itself. The older style heads like the small block Ford, Chrysler, and 2. Small Block Chevys have difficult short turn curves for a CNC machine to get in there and mill properly to the correct curve shape. So far, I have been very successful in gaining more horsepower and torque by further hand porting heads that were previously CNCd. BBC Dart Olds 1. 4 deg. Oval Port. BBC Dart Olds, 1. BBC Dart Olds, 1. BBC Dart Olds 1. 4 deg, guide blending. Another example of hand porting versus CNC would be my customers in the NMCA Nostalgia Pro Street Class. We won the NMCA Nostalgia Pro Street Championship in 2. All four of these various BBC 6. Manufacturers best CNC job. Then I further hand ported those same heads, changed the port and chamber shape, the valve job and short turn curve shape all responded with gaining 8. HP engine gains only, no NOS dyno tests, much higher gains when NOS was used as well as shifting entire torque and horsepower curves  upwards by 3. RPM. Back on the dragstrip in hand ported form, they set ET and MPH records, numerous 1 qualifying positions and won the Championships in those years. But I have to admit in this last year the various CNCd heads Ive been receiving in the shop are much better in terms of port shape and in horsepower and torque gains. In fact just in last two weeks I received another manufacturers best effort BBC NPS style CNC ported head that in my measuring was just about an exact copy of my best hand ported 2. NPS head. Its like they were able to digitally copy my best portchamber shape, yet I know that didnt really happen. It just shows you how quickly CNC porting is evolving. Im glad Ive branched off into computer programming and motorsports software. Those CNC guys are trying to put me out of the porting business. Error Installing Json Ruby Rails Developer here. Its very possible that even a good portion of CNCing may be replaced by Stereo lithography or 3. D metal printing in the future of motorsports. Chrysler SS intake flow bench analysis.

There will always be money to be made by your typical head porting shop or machine shop. Things happen like engine blowups etc., and on CNCd heads you might need to weldgrind repairs, redo valve jobs with Bowl and Chamber blending, re flow tests, new valve guides or resurfacing etc., Or just plain hand porting experimentation to improve or correct a particular CNCd port. One more observation about a CNCd head versus a hand ported head is in the area of the valve job. Free Online Engine Dyno ProgramsThe most critical part of the cylinder head performance wise, is the actual valve job area. With tooling such as Goodson 3. D CuttersBodies the average machine shop or porting shop has the ability to exactly match the CNC machine in the critical valve job area and a little below in the bowl and little above in the chamber with the proper cutter profiles. HRET You pioneered the popular Pipe. Max software program. When did you first develop it and what motivated you to do it and how long did it take to compile the research and write the program LM In the early 1. Radio Shack Tandy color computer also known as the Co. Co computer for which you used your TV set as the Monitor. It also came with a form of the BASIC programming language. I was instantly hooked on programming. Later on, I purchased a Tandy 2. GW Basic language and began trying to correlate all my engine building and dragstrip testing data into software programs that would make it instantly quicker and easier to solve typical motorsports problems such as How much horsepower does it take to run a certain ET or MPH What is the engine RPM at the finish line with such and such rear gears or tire diameter, etc.
