Scotty Guadagno, at PeeGee Performance (cam tests)

  To put it simply, we just wanted to know, for sure, how these products worked. And how they compare with each other, in the same motor, on the same dyno, run buy the same guy. The cam test had been on the "to do" list for TA Performance, prior to the introduction of their updated cam lines. As Mike told me " I just want to be absolutely sure that all of our products perform as advertised". This is rare among the Buick Specialty Manufacturers, calling up your favorite cam grinder and ordering a cam to sell is no big deal. But actually testing each cam is another thing altogether. Spurred by the recent debates over camshaft profiles, Scotty Guadagno was willing to spend hours on his dyno, testing all these cams. A big thanks goes out to Scotty, his work continues to further the development of Hi Performance Buick engines, and the combination of Scotty and Mike are responsible for a good deal of the performance parts we all enjoy today.

    Scotty ran over 40 dyno pulls on the cam test.

  Each combo was tested repeatedly, and the average, not the best, of each combo was tabulated and these are the figures that are reported here.

    The results are reported with no bias, if a non-TA product did well, I say so. If a TA product is better suited for a different application, then that is reported. Fast ramp cams; lifter failure (aka "Crash") are discussed in these pages.

  Along with tons of good info, dyno tested power figures, and general observations regarding various parts.

  On a personal note, I sure hope this puts to rest the whole controversy regarding my experiences with GSCA Popular Mechanics Cam. This issue, and the power levels from this  cam, and an identical copy, with standard hydraulic lobe profiles, is discussed and the data is here, for all to see. Scotty really wanted to do this test, due to the fact he said that he Wanted to solve the problem that he helped create, 10 years ago.
