2001 Dakota RT. This is my first magnum (owned a 4.7 once but ehhh) as i'm a Ford guy. I really didn't wanna start this thread as its probably been brought up quite a few times, but I really cant find it. I have a few concerns such as our trucks being speed density. Now, in the ford world, speed density is a bad thing, robs power if you make it, and everybody converts to mass air flow if you have speed density. Is that the case with these trucks to? Any proven combos or parts that make power? From what I'm finding, people are only putting down 250-270 to the wheels with heads, cam, and intake along with bolt ons. I really like this truck but these old threads (years ago) are kinda freakin me out. Couple more questions if anyone can answer, do these MAGNUMS respond to boost alright with stock heads? What's the bottom end good for? Will this engine perform with $4000 NA? Will this engine perform with a bolt on supercharger with no top end work?

Thanks. Just new guys, don't burn me to hard lol

Dodges respond very well to Intake modifications. The pcm does a good job of calculating air fuel ratio unlike the maf system on fords. The 5.9 is a great engine but hp is not its strong suit. It is however a torque monster. 400 hp would probably require a raised compression ratio or forced induction. You have alot of options on the 5.9. I tend to see 8 to 10psi with a good tune be very reliable. I have also seen guys blow up the engine at 15psi on the stock bottom end for what it is worth. There is a great book out there for modifying the magnum series of engines it goes into deep detail of what can be done.

Dont worry about those old threads a lot has been learned in recent years to make these trucks pretty quick. If you want to get your rear wheel hp to the mid 300s and crank hp to the mid 400s its not terribly difficult. You get a set of edelbrock heads and have them ported if you can afford it. Get a cam in the 210-240 duration lift 500-550. Best intake manifold you can currently get is the indy 360m and will flow more than enough for the heads. Some adjustable roller rockers. high flow 2bbl or 4bbl throttle body. For tuning HPTuners is the newest and greatest. Some midlength or longtube headers would also help a lot. make sure your downpipes are at least 2.5" and if you need to go into a ypipe for a single exhaust make sure its at least 3.5" diameter but otherwise your better off with an xpipe and just doing the 2.5" duals all the way. Also you will need a higher stall converter for the transmission to give you a better launch and you should be in or close to the 12's in the quarter mile. If you want to be any faster than 12 second quarter miles you either need heavy weight reduction, nitrous, blower, or have to remove the engine and do a 408 stroker kit with high compression pistons. Thats where im at right now my last run years ago was a 12.7 @108mph and since then ive done some small improvements like a lightweight lithium battery saving 40lbs, a 25% underdrive damper with a smaller alternator pulley to help charging, lighter weight tires, removed the AC, bigger air filter, so im thinking id be maybe a 12.4-12.5 at around 110mph. Def happy with it its reliable and fun not the fastest on these forums but still respectable lol.
