Anyone,
My engine was ran in and all that on the dyno a couple of years ago. The engine builder then told me to use Mobil 1 Super Syn 15-50 racing
oil as that is what he uses in his race engines and is what he did the dyno runs with in mine after he had broken the cam in. I didn't have mine built out to near the capacity it could have been as I wanted to be able to drive it. Also used a lower profile cam where the power tops out at 6300 RPM and I set the rev limiter to 6000. No where on it can I find anything about VR1 in it, but it has seemed to work well. I do add the STP when I change
oil.
As for the cold start ups and
oil cooler, you can get a thermostat to go between the oil cooler and the filter that won't open until the oil temp is up to where it should be. Here in the Summer with out heat, the oil and ater are already hot by the time I get the cars out of the garage.
Any suggestions?
