 Subject: Stroke, Suck or Blow?
IP: Logged
Message:
hey guys. i drive a mostly mechanically stock R/T with 35XXX miles. in april i will be looking to run 13's in this truck. should i
a)stroke the motor with the 406 C.I. kit (i know its sold as a 408, but its really 406 :)
b)supercharge the truck, with a powerdyne, PROCHARGER, etc etc...
c)twin turbo the truck
i need to retain/improve gas mileage, retain the longevity of the motor (i dont want to open it up again until 125K, and run with new z28's and gt's...what are your thoughts??

Ya know John that a lot of this comes down to what one likes. If the cost wasn't the objective just the end result I would go with the twin turbo system.(and the 408 Stroker kit just for sh!ts and grins) For the same amount of boost the turbo makes more power, but it costs a little more.
I hope that all the opinions of us helps you to find the force Luke.

a 408 project can get verry expencive verry quick!
just a little backround on stroking the 360...
360 with a 4" crank= 402
360 with a 4" crank + bore .020 over = 406
360 with a 4" crank + bore .030 over = 408
there is a guy that ran a 11.95 with a 150 shot on a 360. he used bolt ons, and a big cam.. i am 99% sure the heads were stock. if you just want to go fast, nitrous gives you the most HP and torque and is the cheapest.
if you want a blower, i would suggest a paxton, or vortech. both are verry complete kits. i have a powerdyne on mine, and by the time you buy all of the extra stuff you need to make it work (a ignition with a timing retard, 24# injectors, bigger filter, a METAL airhat, a bypass valve, ect) you could have bough a vortech kit! (i bought my powerdyne used for a good price, or else i would have got a vortech)
the prochargers are not a procharger kit. a company made the kit (cant remember the co.'s name at the moment) and used a procharger blower. it comes with a intercooler, but it sits under the truck and gets the crap beat out of it because it hangs low. the kit is also a pain in the ass to install from what i hear.

yeah, what drew me to the procharger unit was the advertised 70%-100% HP on some apps...anyway, the kit is made by accessible technologies inc, and that kit isnt even complete yet for the r/t...i have the n.o.s. kit on the way, as well as the jacobs nitrous mastermind and a purge kit...are there any other things i should consider to keep me from annhilating my engine??

you might want to think about returning the NOS kit and get the NX kit. i have heard it is the best for the dakota engines. when it comes to something like nitrous, i would want the best.
im not familiar with the jacobs kit.. most use the MSD digital box with nitrous.
just remember to start out with a small shot, and work your way up..i have been told by MANY people, that you can run a 100 shot without taking any timing out, and a 150 shot with 2 degrees pulled. dont hit it under 3k rpm's either.
are you thinking of getting a blower and also use the nitrous? that would be good for cooling the intake charge (with about a 50 shot of nitrous) you could also use water/alcohol mix.

i bought the zex kit, had all of it installed except the fuel pressure line (to the fuel pressure regulator) and the intake line...then i check my chiltons manual and see that our fuel pressure regulator is not run by the pcm or vacuum...so i dont know how the hell anyone got the zex kit to work....if you have a way around that little problem let me know!!! i was pretty damned happy with how it went together and it seems pretty failsafe
thanx guys!

Yep.
NX=foolproof
I like wet anyway, almost no way to accidentally lean out and fry a piston. ZEX is leaned out by the comp, leaves alot to go wrong in my opinion.
100 to 150 shot, I think you could get 13's with just Nitrous.
Good luck with it

Sorry, I just love turbos ... lets all chant together .. Tur-Bo, Tur-Bo!
Back on topic ... have any of the 5.9L guys had good luck with the Kenne Bell kit? I got their catolog in the mail (I was looking for the 4.7L). They claim +100rwhp and +112rwtq. The dyno curve looks good too, average of +100 or so at all RPMs above 3000rpm ... the 4.7L kit looks like crap though.
just my 2 cents

a turbo would be great!!......if it were in the same pricerange as a supercharger.
the kennybell kit for the 4.7 is a nice pice of work, but if you are thinking of putting one on a 5.2/5.9, you have your work cut out for you!

I have looking at all of the different possible forced induction systems. Vortech, paxton, powerdyne, procharger, eaton/magnuson, kenne-bell/whipple, nitrous and alot of turbo companies.
Any type will get you the numbers you are looking for. You have to ask yourself if you want that power on the street all the time too? If so that rules out nitrous. Next question would be where do you want the extra power(top-end charge or off the line whiplash)? Top-end goes to the paxton/vortech type and turboes. The low end you only get from cubes or screw/roots type.
As for gas mileage turboes should be the best. They are powered by horsepower in the form of hot exhaust gases that would normally be lost out the tail pipe. I have heard about people gaining mpg on this site with low boost screw type superchargers. The reason is that the added TQ allows the throttle position to be smaller.
If you decide to go for more power later turboes and vortech type superchargers are the way to go. Screw types are HP limited by thier size(1.5l, 2L, 3L units).
I looked into the procharger unit and I think it has nice features. The intercooler is a BIG PLUS in the amount of power you can get on pump gas. I have seen it used on most of the superchargered leaders in alot of racing classes.
If you don't know how radical you want to go and stay streetable, go turbo. It is the most versitle power adder there is, if you can afford it! I have read in magazines of streetable cars capable of 250MPH. Other cars I've read about that can be driven over 1000 miles and run in the 9's at the track!
If you think you'll be happy with 12/13's I would go with one of the superchargers.

its a BIG plus if you can keep from knocking the intercooler off!! have you seen how low it hangs under the truck?? it is also a verry small air to air intercooler... it is better than nothing...if you can keep it on the truck.

I have never see the kit on a dakota but I have seen what thier kits can do. The intercooler location could always be tinkered with to solve that small problem. Was the dakota you saw it on stock hieght/lowered/2wd/4wd?

the kit i saw it on was a stock hight R/T. i dont really see another spot you can put it without it being out of the airflow stream.
most people who use the kit just leave the intercooler off, and then it does the same thing as the vortech, and paxton...except the vortech and paxton kits are superior
keep in mind that it is NOT a ATI kit. the company just used a ATI unit, and made there own kit out of it.

i dont know the dimensions, but you could probably get it to fit between the splits in the stock facia. (i told you its small..lol)
seriously, it would be better to use a blower with no intercooler and use a alcohol/water injection system or a nitrous system to cool the intake charge.
