Have lots of run time on it now and have made a few tweaks. I do have to run 93 octane or she pings. Put a gauge on it and adjusted the boost to about 3psi normal and as high as 4.5 psi when really flogging it up a long hill. This appears to be about all the turbo will deliver as the boost relief valve is essentially just a big spring clamping off the valve. I don't know if the valve is leaking or if... I have the compressor housing from one turbo and the exhaust housing from another so maybe I am getting a bunch of leak by on the exhaust side. Have a big 6 mill hard climb near the house, each time I have gone up it the Jeep is overheating by the top. the temp climbs from 190 to 220 and I don't dare push harder so I back out of it. As a result it takes longer to get up the hill now than it used to. Bummer.
I cleaned out the SAAB oilcooler and installed it as an aux rad. For those familier with the CJ, it has a air scoop behind the grill so I mounted the cooler in front of that outlet. I know an oil cooler has less flow but then the flow is limited by the output on the turbo and I know it is more than that. I have it ported where the hot water comes from the carb base, into the cooler and then into the turbo before returning to the block. I think it should be after the turbo but this is the set up that works best. If I notice a big difference then I will think about reworking the hard piping to switch. In testing the Jeep took about the same time to come up to temp (185/190) and wouldn't go above that on flat driving, but then it didn't before so that is sort of a crap test. Looks like the big hill and I have to go another round soon. Cooler did get nice and hot so some heat must be wicking away regardless.
Have a very loud valve tick and clatter but that is normal. I think I am being extra sensitive. Getting more oil out of the breather tube, contemplating stuffing foam in the tubing in such a way that collected oil can run back in rather than into the air box and then onto the ground. As this air box setup is all new to the jeep I can not tell how much is if any is related to the turbo. Going to check compression and see if I am getting blow-by, but as I forgot to do so prior to starting the project I can not see if anything has changed. Moron.
