Spencer and Remps---- Thanks--- I m asking because I WANT to hear the voices of "been there done that"...….
I understand your point about over-airing just causing more drag on engine and mpg loss. I drive this truck pretty conservatively.
With the gear vendors overdrive I now have 8 fwd. gears to go through from stoped to 75+. I can feel the pressure giving me a little
kick in about the upper 1/3 of the RPM range before time to shift. The middle 1/3 is OK but the lower 1/3 is a little slow to pick up.
Im thinking the H1C is probably kicking in when it is designed to--- it just seems like I would like 3 or 4 psi off the line instead of zero.
I guess that lower 1/3 is the engine just being non-turbo'd.
Also---- I THOUGHT I has a oil leak in the core of the turbo--- as I was seeing a little oil on the outside of the housing. Before I turned the smoke screw out a half turn a couple days ago--- I gunked and rinsed the turbo to try to spot the source of the leak. So I drove it about an hour --
and later looked at the turbo and its dry as a bone outside now. NOW-- Im starting to wonder if having the smoke screw in too far may have
been giving me a idle that was slobbering with unburnt fuel--- and that fuel going through the turbo was mixing with the soot in there and just
slinging off the blades and making its way out through the stepped "seals" which don't really seal. (where the housings meet the core)
I m thinking that wasn't oil I was seeing but a fuel-soot mix. SO--- if my core is OK and not leaking--- maybe I could just go to the next smaller housing. I assume I have an 18 on it--- and I see 16's are fairly cheep--- but whats up with the price on 14 inch housings????? Like 160$ vs
350$ ……. what am I missing there??????
I tend to agree -- maybe even the HX-35 might be more than I need airwise. I just want to perk up that lower 1/3 so I don't have to wait on it to kind of catch up. Soon I will fill up and test my fuel mileage. I hope it might be in the upper 20's -- but who knows.
Thanks for the ideas --- keep em coming if you have em ! I hope Richard Roundtree isn't reading this thread----
