I have over 130 dyno runs on a 1987 LT250 that we did with various stages of porting, carb changes, head changes and intake system changes that were made a couple of years ago   We tested the following pipes and silencers combination of the Paul turner, Dyno port, DRQ/Shearer, FTZ in frame, FTZ drag pipe, and some other pipes than I could not identify. When we got to the more radical stages of porting, some pipes dropped out of the race because they did not complement the radical porting.   I can post some of these runs as long as the cheerleaders for some of these pipes do not get their feelings hurt or start another Sh.t storm like when I posted the test results for the HPR19 for the LT500.

 I am a mechanical engineer that designs and produces stuff for my company and the companies that I do consulting for.  I make my decisions based upon the test results I get from field testing, dyno testing and data acquisition in the field, not on hear say, internet polls and or folklore that seem to be apparent method of testing that some of the other companies must be using.  If they were more through in their testing I do not think I would see the test results I see when testing their products.

 These were dyno runs we made when we started development on our HPR pipe to see what we are competing against.  I am a fierce competitor and do not release products until I have convinced myself that what I have developed is head and shoulder above the competition.  We have one HPR design that looks good but I want to develop it a little further before we go into production.  I do not know when I will have time to finish this LT250 pipe development due to my time situation and search for more good employees.
