Hi all, I finally fiddled with the full load fuel delivery (and max RPM) on my injection pump this afternoon. Details are here:
http://buymbparts.com/forum/showthread.php?p=2262&posted=1#post2262 Short version is that it worked OK, there's more power, but EGT's increase too much with extended full throttle. At the moment I have no intercooler (IC) or water injection (WI). Although I would greatly prefer an IC setup, I don't have the time, money, or parts required to complete this anytime soon. Maybe next year, if I can find the prerequisite AMG bumper needed to swallow the IC. I'm planning on trying out a WI kit as soon as possible, maybe the one on eBay linked to in the post above. Theoretically that should allow a full 1.5-1.75 turns of the full load screw, providing the same ~20% power gain that Casey is seeing on his intercooled 603, with the same low EGT's. I will have dragstrip data this Friday on how much quicker the car is. I believe I will be able to do 1/4 mile runs at WOT without getting into the danger zone (1300F+) but I'll be watching the EGT's closely! :-) Best regards, Dave M. Boise, ID
