How do full mechanical turbo pumps with no provision allowing for the non-linear affect of turbo boost compinsate in terms of AFR?? I dont get it.... I have rebuilt/re-calibrated loads of old 6.2/6.5 NA pumps and its a straight curve following RPM and metering valve position on the NA pumps, so whats different?
If full mechanical turbo pumps do a good job of controlling fueling, are the electro/mechanical pumps that much better? What do the electric FIP's do better than the mechanical pumps (boosted application)? Are we talking about a night and day difference or maybe just a few HP and 1-2 mpg's? Obviously I have no experience with the electric over hyd (or whatever) FIP's.
If I get a 95 6.5TD, can I ditch the electric stuff and just use a full mechanical pump for simplicity? Is this a bad idea, good idea, ect? I would be doing a HE351CW, HX40, or maybe a VE eventualy, and ease of tuning is important to me. I have a donor 6.5TD with 4L80E from a 95 3500HD on standy, for swaping into my CUCV.
Thanks.
