These cars are costly after the DCAI, pulley and tune. Knowing what to expect with the mods available is important. I figure I will get a 5% increase in SC rpm's at the SC pulley. I don't know why but I run 18-19psi with the mods listed which is high according to JR McDaniel who sold me the 178/PSK. I sent him a short datalog showing the 18psi and I believe the 19 also. 5% could be an increase of about 1psi or 20psi. that seems to be where I will not need excessive amounts of fuel mods and tuning. In fact it could be my AFR's could be leaned to be closer to the 12.2:1 goal I have if Jerry has me a bit rich which I would suspect. I believe from all of the posting and PM's plus research that a pump and an adjustable regulator(and free flow filter) should be all I will need.
If I have the stock pulley turned to 69mm I would get an 8% increase or almost a 2psi increase. The SC would then spin at about15,500rpm. Too high or not. I cannot run Rob's heat exchanger due to lack of room seeing I have an SLK. Not sure what could be done to help cooling. I have a wideband O2 ordered but it is delayed again, might have to wait until the end of the month. Then have it and all pulleys installed the same day with a run to see what the AFR's are with the current tune and the 155/65 pulleys. My timing jumps all over the place for no reason that I can see. I will also stop running TORCO and stay with the 93 octane tune. Just wait now. 70 or 69?
