Charles,
Thanks for the info! Our 13.5 A/F at WOT is/seems too lean (on the edge at
least) even with the "learned" 270cc injectors still going to try the fuel
pressure mods just to see the diff in A/F (Clayton dyno w/ Hiraba (sic) data
aq.) We are "trying" to work with JET to get more timing, at least a couple
deg. I got the same fool story from the front desk guys (no comment) but
their engineer is sharp and seems to know whats up. they made an offer to
Frank re: come on down for a looks see on the dyno, (taking advantage of the
lack of Mopar SBEC for 98-99) I like the sound of the R/Ts Ultra flow, so
it stays, but 2.25 head pipes are in the works (dropped the truck off @ JBA
this am. Not sure how the transistion is going to go to the 2" cat inlets,
but Im thinking slip over the outside instead of the inside like it is now
(2" minus 2 walls= too small) and a gentle transistion from 2.25 to 2.1 or
so to slip over... My bucks are there (for me) to play with!! Money + no
toys = no fun...

Subject: DML: answers to questions
Here is my opinion on subjects asked by various members.
1. Bruce and Frank: In "Holley Carburetors & Manifolds",page 12 and also the
CAA
aircraft mech. manual(1947)hp curves of A/F flat from 12.5 to 13.5. After
13.5 curve
starts droping off faster. Anyway 6 hp is what you get. One would run in the
12.5
range because of high supercharger pressure, high compression or to much
timing or
a combination of all three. If things are not kept out of detonation things
break.
2. I am using a 3" FLOWMASTER on my R/T, sounds good and feels like 8 to 10
hp.
3. Am also using BOSCH PLATINUM spark plugs gapped at .060. If you have
enough
voltage to jump gap will be worth 5 hp or so. Platinum plugs last forever
(100k
on my chev truck) and sharp point from fine wire means you need less voltage
to jump
gap.
4. If you use 75w-90 synthetic gear lube in rear end good for 1% hp gain hot
and 5%
cold. 1% is not much but it would be forever and you would save a little
gas. Go to
the Redline web page to get the info. Be a good reason to put a crome
differential
cover on. Only 17.75 from MOPAR.
5. I have a 180 thermostat and water wetter. Also have a Jet Stage 2. Before
I put
on the K&N when things got louder I was running 87 octane gas with no ping.
Called
tech. guy from Jet and asked how much more timing I was getting. He said 4
to 8
degrees more. I said how come I can run 87 and he said cause your knock
detector is
retarding before you hear it. I said goodday and hung up. Dudes, there ain't
no knock
detector in DODGES. You will have pinging with the MOPAR part on 87 octane
but at least
you the know it is advancing the timing and making more hp. Me thinks Jet
part worth
about 1.98. Save your bucks and wait for MOPAR part.
That's my my .02s worth. Hope it is of some use to someone.
