I just finished up installing the Jeep GC upper hose on my R/T. I
didn't like how short it was, pulling against the A/C compressor lines
and all, so I took the thermostat housing to a muffler shop and had them
add 1.5" to the overall height (5.5" from base to tip). They cut it
apart with a chop saw about halfway up the thick part and migged in a
1.5" piece of 1.5" muffler tubing. With the hose and t-stat housing
off, I routed the throttle cable under the A/C lines to get it lower/out
of the way. Check for proper throttle action - it seems to make the
cable pull tight - my pedal didn't change. The upper hose now clears
the A/C lines by 1/4", instead of pulling tight against them. I also
took this opportunity to install a 180 thermostat.
Installed the 14" (12.75") Mopar air cleaner - WOW, it looks great.
It clears the alternator brace stud by 1/2" or so. The element is 2.75"
high, and that's all that will fit with this unit. The air cleaner, as
it comes, does not touch the hood pad. I set a pencil (1/4" high) on
the front edge of the lid - closing the hood smashed the pencil, so a 3"
element won't work. The Mopar lid doesn't come with a fitting for the
PCV valve hose, I had a stainless 1/2" pipe x 1/2" tubing "Swedgelock"
90 degree fitting in my junk box that works perfectly. I punched a
13/16" hole in the base, put a 1/2" conduit nut on the fitting, stuck it
into the hole, and tightened it down with another 1/2" conduit nut. A
short (2") piece of 1/2" tubing is required to finish it off. NOTE:
none of this will be visible, so use what will work for you. The
fitting is angled directly at the firewall, I used the stock PCV hose by
cutting off about 5 - 6" from the PCV end. Used the stock hold-down
stud by cutting it in half and adding a 1/4" nut, 1/4" x 1" long
threaded nut (Dorman box at hardware store), the top half of the cut
stud, and another 1/4" nut - all lock-tited of course. It only needs be
3/8 - 1/2" longer than stock.
Now the horror story. My first runs on the G-Tech showed 193 rear
wheel horsepower, that at 300 or so miles on the clock. Decided to
check it this AM on the way home from work, and could only get 174???
Can these meters go bad? The only changes I've made were: oil change @
550 miles (10w30 Dino oil), 180 deg t-stat & Jeep upper hose, last 2
fill-ups with premium gaso. Oddly enough, I lent the G-Tech to a friend
with an old hot rod Ford Pickup that keeps up with and occasionally
beats a bona-fide, track tested 12.80 sec Nova. He could only get a
14.6 on the meter, (VERY traction limited this day), even with 15" tires
on 15x14 rims. Needless to say, I don't know how reliable this
particular G-Tech will be.

P.S.
Got the air cleaner from Koller Dodge - they did give a 25% discount on
the order, even though the web site shows only 15%.
