No charge of course. Now he bought a 20B over the internet and has that installed (I made him some mounts). Then his job evaporated, and the city was going to tow his car for lack of tags. He has no money, and no place to work on a car, so I told him to bring it here and trade cleaning the shop and helping me once a month he can do his stuff here no charge. So then he has no way of moving the car, so an old friend who I build old restored car engines for, is called for a tow vehicle, he says sure. I get a tag for the only trailer I have left, and off we go to Lancaster Ohio 28 miles away. And after 4 hours of filling flat tires, and unsticking rusted rotors "Presto" his car is in my shop. It is a piece of crap, and a waste of a 20B, but when we get done it will look like a realy nice bone stock (2nd generation) white. I like white.

Those can be disassembled and a few washers installed under the spring to bring top pressure up to whatever you want. Racers like 75 to 100 pounds, the stock twin turbo FD is set at 115 pounds. The .Weber jet mods to the oil spray nozzles in the crank are there to preclude a piece of broken spring from finding its way into the oil pump. Also to control how much oil gets sprayed into the rotors for cooling. Racing Beat says a 200 main jet is about right. I use a 180 air corrector because I had a lot of them and it fits better. I also use 100 Pounds from a dry sump pump and do not want too much oil going into the rotors to limit foaming. If you do this mod to a street engine, the idiot light will blink all of the time at idle. Too big a leak in the oiling system. Once you have a few revs on hand the pressure comes up a bit and the light goes out. The rotors foam the oil badly and that reduces oil pressure and heat transfer (from air in the oil) . So if you have this mod your idle pressure will be below normal, and you peak pressure will be a few pounds light from oil temps and (bigger holes). Once at top RPM, the only limit on pressure should be the relief valve cracking pressure. You can check that with shop air pressure before assembly. You can mod the early valves to get more pressure. You can use a heavier weight oil. Racing oils have more anti scuff compounds and more anti foaming additives. You can limit oil temps. You can buy an 85 or 110 pound valve from Racing Beat, or make one yourself. Reinstall the valve with the drain horizontal to help reduce foaming. That 68 pounds at full throttle and full temps is plenty, bearing wise, just not as reassuring as 85 pounds. Be sure that there is a restrictor in the pressure line to the turbo. The next time the pan is off, just mod the valve up to 80 PSI and settle for 75 pounds at cruise. It won't make any difference, but You will feel better, and we will feel better. Lynn E. Hanover PS.
