When I bought my exhaust system from RacingBeat they sent me this black book that has lots of cool info. For any of you who own this book, turn to page 52 and look at step number 5 under "Supercharging";

Step 5. If it is possible on your vehicle to do so, adjust the output on the metering oil pump unit to double the flow at 2,000 RPM. If the flow cannot be adjusted then you need to premix.


Well I dont want to waste time and run premix, but I would like my engine to consume just a little (not double) more oil so that engine wear is hopefully reduced.

Does anyone know how to increase flow on an s4 tII?? How about any of the other 86-92 rx7s??

 

You jerk, I got no such book =(

 

Amazon is where I get my books. Get Maximum Boost by Corky Bell. Its good!! Also get the new rx7 book by Brian Lang!! I forgot the title!! Racingbeat was nice to me on the phone. They sent me a T-Shirt and the book!! and I only spent 160 bux!

 

Im not saying those guys are totally wrong or whatever, but give my experience with taking apart stock core motors, if you dump in that much crankcase oil via the stock OMP youre going to do nothing but a) consume more oil b) smoke a bit more, c) cake carbon buildup on your rotors like mad and d) foul plugs over time.

I would go with premix ad an addition if you feel it necessary: the premix will burn clean, and not leave behind deposits, while still lubricating the internals more and better than the stock system.
