 Subject: Where Have I Been?! Hughes Project!
IP: Logged
Message:
Not to say anybody noticed, but... :-)
Since the end of June I have been upgrading the '99 Dak 3.9 AT RC SB with parts from Hughes Engines. My project is similar to Fed's and Huggins', with inspiration by the revered Larry of J&J fame...
Cam (HER1828AL), head work (HPS2-MAGV6), Stage II intake manifold (5517-RB), head milling (approx. .040", about 10:1 comp), roller rockers (1538-12), JBA headers (titanium ceramic), and Stage II reflashed computer (23002).
Also many other minor things such as Flow Kooler water pump and thermostat (the thermostat required milling the hole to a larger size!), March "Power and Amp" pulley set, and ARP intake and header bolts.
After some minor things are sorted out I will post pics of the whole truck, with dyno results later, as the computer needs time to get its bearings due to the reflash (by B&G) and the cam (which seems quite radical, especially for a 239 c.i. engine!)
"Before" (with the mods in my signature) RWHP: 150 (with 42RE auto trans)
"After" RWHP: 250+ (?)
Later to come will be some lower rear gears-- 3.92's or 4.10's; haven't decided which yet! Also maybe a higher stall torque converter...
The truck is now reassembled and on the road! The "butt dyno" says there have been increases all around (especially from 2500 RPM and up!). The vacuum gauge indicates about 10-12 inches at idle versus about 18 inches with the stock cam, intake, etc.
The two latest issues are to hook up the heater (winter is DEFINITELY coming to N.E. Indiana) and to see about a "slide-bump" where the trans hunts between 1-2 and also shifts softly. This was at the same time I noticed the cooler lines resting on the driver's side header. I believe it to be either overheated fluid, a leaking accumulator, or an out-of-spec throttle valve (not the cable, but the valve), or some combo of all three!
PLEASE, PLEASE everyone who reads this post give me your opinions: good, bad, indifferent, go see about the neighbor's goat :-), and advice and experience about the whole project! This site is full of people who always have something to contribute that makes all our Dakotas better, more enjoyable, or at least more understandable
:-) and I appreciate you all!
Awaitng posts from all!
Cheers!

higher stall TC and 4.10's would make a nice upgrade for what you have. larry mentioned something a while back about a factory TC with maybe 1200 or 1800 stall. available for a reasonable price.
good luck and hope your having fun with it.

congratulations Purple1!
glad you decided to tune up that 3.9..
i have about 2,500 miles on my baby but im not yet finished with
the "bolt ons".. (i still have the stock manifolds and
throttle body in there due to low cash)
so you went with the towing cam huh? and you say it is quite more
radical than stock? by the tone or specs? because my cam
(last four numbers on hughes part number - 0814)didnt make
the truck sound MUCH more different than stock...
but i can sure tell the difference in power from 1800-5500 RPM like
they say and MORE to come once i buy that bigger throttle body
i hope your truck runs sweeet buddy

Sounds like you got yourself a nice ride there man!
I live near Indy so we sound like fellow Hossiers!!
I would like to do those mods to my 1999 3.9L also.
If I was to get the Stage II intake manifold (5517-RB) while useing a 48mm TB and not uping the Cam to a (HER1828AL) till later on in life. Am I going to have trouble with this?
Would it be better to just get the Stage I intake manifold and 48mm TB and later on in life install the (HER1828AL) Cam?? or will the Stag I intake not be enough?
Or will the 48mm TB be to small?
All I can really afford right now is the TB and the Intake manifold, but if I buy the Intake manifold I have to quickly install it so I can return them my original intake manifold so I can get my CORE deposit back. :(
This stuff can be like a really tuff puzzle to put together on a TIME/CASH budget and with not a lot of knowledge to go on. Sometimes I want to just give up but I just cant stop thinking about my truck. (I even wake up in the middle of the night thinking about this stage I vs. Stage II stuff)
Please help

Hi, Guys!
DodgeDakotas.com members: Also see my post on the "Members" page. If you're not yet a member; whaterya waitin' for?! Just kidding!
Here's the URL for the tech article on cam choices for "Magnum" hydraulic rollers:
http://www.hughesengines.com/general/techArticleDetail.asp?articleID=1000017
The cam I originally planned on was the HER0814AL, but in talking with Dave and Kevin at Hughes they recommended the HER1828AL due to my desire to raise compression.
And the full specs for the HER1828AL:
Intake Valve Lift 1.5 .510
Exhaust Valve Lift 1.5 .510°
Intake Valve Lift 1.6 .544
Exhaust Valve Lift 1.6 .544°
Intake Duration at .050" 218
Exhaust Duration at .050" 228°
Lobe Separation Angle 114
Intake Opening at .050" -2 BTC
Exhaust Opening at .050" 51 BBC
Intake Closing at .050" 40 ABC
Exhaust Closing at .050" -3 ATC
Min. Suggested Cylinder PSI 165
Sweet Spot RPM 2300 - 6100

...About 120 a month for the next 5 years! :-)
Seriously, all of 5K and then some! The head work with the right springs and the headers were the stiffest part!
Say: do you know how to type the little "degrees"
circle? I'm not computer literate enuff to know, I guess!
CluCool:
I live In Auburn, home of the classic Auburns, Cords, and Duesenbergs (320+ horsepower in the 1930's from the Model SJ! Puts most Indy cars of the era to shame!)
The cam I chose is probably not for everyone! Plan on gears and a higher stall converter (If you have an auto) than you probably have right now to get the most out of the -1828AL and the stage II intake. Throw in 4WD and-or extended cab and the plot thickens! These trucks are heavier than most people think! More curves; more weight, I suppose!
I'm not one of the heavily experienced techline guys you talk to when you call top places like Hughes or KRC so I'd suggest you read Hughes Engine's tech articles on the "Magnum" engines and mods to them. They are very helpful.
My feeling would be that you might look at your intended use for the truck and curb weight, stall speed, RPM range, etc. You might end up best suited to the Stage I intake, -0814AL cam, and 48 millimeter throttle body-- I'd pop for one of the billet ones myself. Mine is a Holley 112-556 and is fine, but if I had to buy one again I'd prolly go Hughes or F&B...
It's all in the planned combination of parts where the most horses and best performance are!
"Stage 1" and "Stage II" are just names some companies use to illustrate the way from "mild" to "wild", it also illustrates how these mods work together to boost power
In my experience it might be best to send them your existing intake to mod, rather than do the "exchange" thing. This would be so that you can be sure to get the exact same intake back. I didn't the first time, but that was the fault of my assumptions!
I def. understand the finances! For me, this was a dream of the last two years, finally catalyzed by those pesky broken exhaust manifold studs causing leaks (Lesse... head must come off, mayas well take both, get a valve job, etc... Why not take the plunge and do it now?! Crazy how some people's minds function, huh?!
Couldn't have done it without the friend at the credit union!

Sorry to be so wordy, but:
Sometimes I can't sleep at night either, due to thinking of the Dakota! It's been this way since I bought it new, I guess!
Whatta hopeless case I am, huh!? :-p

Hey Purple, I have a 2wd Reg cab. so it is just like yours and what you have goin on sounds exactly like what I want to do to mine.
Well I want to build my truck up in time like a 2-4 years. Man that sounds like a long time, but I will be debt free in like 2 yrs, (other than house payment) So before the 2-4 year spam is up I hope to have these additional bolt ons (Throttle Body/Intake Manifold/Superchip Tuner/24lbs. Fuel Injectors/Viper Electric Fan) I already have
Clear Corners
APC Tail Lights
Vent Visors
3rd Brake Light Cover
White Face Gauges
White Face A/C Cover
AirAid Cold Air Intake
Air Intake Temperature Sensor Mod
ASP Crank & Alternator Pulleys
E3 Spark Plugs
MSD 8.5mm Wires
Accel Ignition Coil
Accel Distributor Cap
Accel Distributor Rotor
Fiberglass Roll Pan
Gibson Split rear Exhaust
Magnaflow Catalytic Converter
Gibson Headers
I plan on putting like $10 G's into the trucks engine tranny and gears. I dont plan on doing any of the work because I have tried in the past and learned to leave this stuff to the professionals!
I will,.... if all goes well be able to spend the $10 G's and pay it off in 3 years and another 10 will be availble. (dreaming big, but not that big)
So I think that much money will do me some good my goal would be in the end is to have a daily driver, but doesnt really need to be great on gas.
I would like it to be fast, but not have to tinker around with it every day to get it to run. Periodic check ups every couple of months is fine though. I want to get an air ride suspension and 20" rims. Do some body mods maybe some other year, but eventually yes.
If you cant tell I plan on keeping this truck till I die or till I am forced for some reason to part with it. I have had it since it was brand new.
To get to the point (my original post above) I wonder if I take my truck to the shop I plan on haveing install the intake manifold and have them answer all the questions at the bottom of this page
http://www.hughesengines.com/partDetail.asp?partID=11765&eTypeID=15
That would probably help me get the right Stage II intake Manifold the first time right?

2 things here
going with a throttle body that has bigger plates
than the bore on the intake does you no good and
will hurt off idle response and low end torque
The hughes intakes are 48mm unless you ask them
to open to 50mm I done this with my 4.0 stroker
motor with a 50mm F&B 309/322 rear wheel 4.10
The 48mm will flow fastman or the F&B 650 660 cfm
unless your blowen or running nitrious this is
all you would ever need the 50mm flows like 725cfm
On the vac signal plug the throttle body vac
sorce turn the rubber elbo and run a line to the
test port on the drivers side of intake manifold
this will give you a higer signal more vac
what I use is like the air shock line the white
plastic line an adapter and plug it on this is
a common problem with hotter cams that most over
look doing this will help a lot with off idle
low end respose and idle quility
The 4.0 stroker crank with 10 to 1 comp will add
50 hp and lots of low end torque just by its self
stroker kits.com around $2000 it will bolt right
in but you may have to gring about an 1/8 off
the block behind the 1 counter weight it just
touches the block some blocks will clear
The local off road racing team we do work for has
7 stroked V6's also where I got my cranks from
they use the wider and heavier 318 rod this can
also be done to the stock crank with some machine
work
