I am wondering about gauges and their importance; specifically, oil temperature versus oil pressure. If you had to choose between the two, which one would you pick? And does it matter for a street car versus track car? Ben

It's been a long hard road to get to 1:41.0, but we've arrived. We are nowhere next to finished so you can expect even faster times in the near future, but for now winning the Source Interlink Superlap Battle at Buttonwillow Raceway, CA two years in a row is pretty damn sweet.

So what was the cherry on top of our Nissan SR20DE horsepower upgrades? S4HL Camshafts from Jim Wolf technology. What are cams? First, let’s start off with the term “cams”. Cams are actually the lobes of the entire assembly, which is more formally known as the camshaft. But, for this article, we’ll stick to calling them cams, as that is the casual term for the part. So, let’s give a little introduction on the basics of cams.

I have a 1996 Mazda Miata with a Jackson Racing MP45 supercharger and an ECU controlled Aquamist water/methanol injection system. The water tank I use is about 3/4 gallon in size, so when I fill it up with straight windshield washer fluid (no additives, just water and methanol) I'm running the tank dry well before my 30 min. track session is complete.
My involvement this year supporting Dai Yoshihara and James Deane with Falken Motorsports in Formula D drifting has been a wild ride. It was a very interesting learning experience as I finally discovered what the dynamics of a really good drift car are and how to set up the chassis to deliver the performance a driver needs to do his job. Modern Pro drifting is probably the greatest challenge for chassis set up out of any sedan based motorsport and the SPD Metalworks crew works pretty hard to get the car just right for any given course.
Nissan's exciting new MR16DDT engine has all of the features and stats that you would want in a kick ass engine. It also sounds like it may have what it takes to be Nissan and/or Renault's entry as the GRE (global race engine). Imagine seeing this engine in the back of an F1 car...

The last test at Buttonwillow was the straw that broke the camel's back both for the choice of turbocharger and the cylinder head sealing issues. You can see the despair (and my head scratching) in the picture above, but with any down there's always going to be an up. BorgWarner with their EFR turbo lineup and Cosworth with our turbo race engine experience are coming to the rescue.

Elmo makes some more progress on his bad ass CRX. AP Racing monobloc calipers, Recaro Kevlar buckets, and other goodies make this CRX probably the most baller CRX around.
