hey skip, for what it is worth, I would suggest running as cool a thermostat as you can find, using the stock radiator setup, and obtain a compressor tio get the AC back into operation. you already seem to have a handle on watching the oil and coolant temps closely, the coolant extracts a lot of heat from the oil in the block. all this would seem to help to lower te underhood temps, which I believe is where the real performance gains are to be found. the old formula I believe that Smokey Yunick used was as follows: for every 10 degrees F that you decrease the temp of the intake air, you get a 1% horsepower increase. I think the motor in question for theis formula is a "typical" 300 horse chevy v8, but the logic still applies- cold air is denser, has more oxygen per volume. Plus, I would hate to have oil and coolant that close, in case you had a hidden leak allowing coolant and oil to mix. I am not actually clear if the condenser is seperate or a part of the existing radiator- so if it is seperate, then disregard last comment. In my n/a brat, I was amazed at the difference in having a mechanical secondary carb, advanced timing, and a free flowing exhaust. I never believed the ea81 had that much throttle response. But, still, at 90 mph or so, it really shows that it has 70-80 horsepower! I would rather have some intercooling setup that would allow more timing- subaru's seem to be timed very conservatively, and insulate everything to keep heat in the exhaust and out of the intake air. hope this helps.

Would you like me to delete this thread? Or are we waiting for Skip to respond to it?

 

Im working on a new style for the USMB that is the same as the default style, but acts differently. Like taking the "new thread" button out of the thread view, so you can only reply while reading a thread.

 

Anyhow.
