The Datsun P510 - Just why it was so damn good.

I recently found this video made of the P510 BRE Datsun and I soon realized that what was already known, done and achieved on track as far back as 1972 may just put some myths, uncertainties and non-believer preposterous ideas to rest.  Peter Brock of Brock Racing Enterprises (BRE) was a racing fanatic, an engineer with very high standards and along with the help of the Japanese, a superb engine builder,  some very clever thinking and using what was permitted within the Trans-Am series rules eventually overcame the opposition and they went on to win the Tarns-Am series back to back (1971 -1972).

What may not be well known to many was that although the Dastun P510 2-door originally came out with the 1600cc L-series engine, during 1972 it was permitted to make use of the 1800cc L-Series engine (also raced by team mate Mike Downs) in the 2.5 Trans-Am series championship.  It also made use of the Datsun 240Z gearbox among other changes.  However that was not all, it was the unbelievable handling, weight and balance of the car which all added up to being the total race package making it a double championship winner in the capable hands of John Morton.

The attained engine power was not so far off from what we have always believed is and was always possible and even by today's standards using a slightly bigger engine capacity configuration in the B210 Datsun (140Z) and using a camshaft profile which was not available in 1972 it is not that surprising then that it only makes roughly 40HP more than it did 40 years ago at Lugana Seca.  It may just very well be that the BRE team engine builder knew then and may indeed still know more than even what 'Mr Datsun' today knows about the L-Series engine given what they achieved 4 decades ago. 

As it is so aptly stated in the video, it takes a very brave type driver to extract the maximum from these old cars and perhaps it must just be accepted that when you have both combinations in your arsenal as a race package, it usually is simply a cut above the rest.

Having now watched the above video perhaps you may want to spend some more time (26min) watching the next video featuring some original footage of the Trans-Am series history of this BRE Datsun taking on the bigger engined cars and beating them.  After all its nothing new and it indeed still continues to this day.  So what's really changed?
