Thanks for the info on the TST #s. The info is valuable to me.
I read the entire newbie info. post and all the links in it in the past few days with interest. The 0/10/100 fuel plate explanation I think I understand pretty well but TST seems to provide more incremental steps toward the power level goals one might be after. I tried to post my truck profile but it doesn't seem to like the way I put it in, so here it is: 1997 Dodge CTD 25OO Ext cab HX35 47re w/billet TC, lock up switch, & Valve Body 3.54 axle 235x85-16 tires pretty much stock except for the trans.
I know these engines were de-rated due to the drive train problems, mostly the transmissions. With the BD kit, TC lockup switch, and billet TC I believe I can move up the power to the design level the engine was originally intended to produce for road use. I just don't know what that was. I am after efficiency and mpg. 95% of my use is running with around 7100-8500 lbs. on the truck alone and get around 22-24 mpg highway. I did have a really heavy gross combined load the other day for around 800 miles and It handled it fine, but that is not the typical use.
I read....somewhere....I think in the turbo link, that a stock HX35 is good for up to 300 HP which I'm sure is more than I need. That suites me fine because they are economical and available if needed (I have 165000 miles on my truck). I don't want to mess with studs in the head or replacing valve springs and they don't appear to be necessary for my goals.
I don't like running over around 2000 RPM and can't recall going over about 2200-2300 ever. I just don't need it.
I want my EGT to stay as low as is feasible (my wife may drive it some) but am thinking a combination something like this:
-#6 or #8 fuel plate with required AFC mods/adjustments and Mack rack plug (is this plug needed for my use?)
-valve in the waste gate line and boost adjusted to 30 psi (note I live in colo. Elevation issues?)
-Timing advanced to 15.5 degrees
I do have EGT/boost/fuel pressure/trans. temp gauges. Any advice or comments would be appreciated. Sorry about the long post but I think it covers things pretty well.
