hi i need some help with my 98 ram 5.2 it has a lack of power so bad that i can not even spin the tires at a
dead stop the truck just bogs then will pick up speed slowly would like anyones help!!! thank

 

wat size tires do you have on it.

 

check and see if the death flash has been dun to your truck dodge did this on some trucks to reduce pinning. if its been dun there should be a sticker on ither the pcm its self, the rad support, in the glove box or on the inside of the hood. check the cat the stouck ones go out fairley quick. has it always been like this or just recientley?

 

i have 20in rims did Hypertech Tuning to adjust for tire size a flash was done on my pcm sticker on core supt reprogram power train
and had new Exhaust put on 6 months ago just changed fule pump new Alternator 160amp with 0 gage bat cables

 

I con't light my tires up either from a dead stop and I have a 5.2

If you have the sticker on on the PCM thats the death flash, but the hypertech will fix it.

What gears do you have? Any performance mods? How big are your TIRES? Don't care about wheels

Also how big is your exhaust? Is it just a factory replacement? Duel's? 3"? 2.5"? 2.25"? All these answers can help us

 

ok sorry gone for a day exhaust is 6 month old singel into duel 3in 3.55 in the rear end tire size is 305/50R20
i am also thinking about geting this for my truck to The Tri-Phase Performance Module from nextlevelracing.com
any body know some thing about this

 

what is the tri phase pref mod? whats it do? obvusally i dont know anything about it thow sorry

 

I'd sat a combo between your gears being a bit small and your huge exhaust. With a duel 3" exhaust your loosing alot of backbresure, which looses low end tq. I've eard on here fom r afew people that 2.25" is the way to go to keep that low end.

Your tires are 32 X 12's. With 3.55's thats a little on the small side.

 

2.25 is the way to go...if you want 3" the surface area difference between the two only gets close if you got single 3" or dual 2.25" any type of EFI motor requires a certain amount of exhaust pressure retentain/restriction... backpressure... you also gotta remember them 20's you got on there are heavier then the stock 16's or 17's .. added rotating mass adds drag on the drive train

if you got a 160 amp alt you could think about going elec fans... i was surprised how easy my motor wanted to spin faster and faster... i never had a problem with roasting the rubbs .. but with my mods it takes less effort from my right foot to perform a jaw dropping smoke show...

where did you get that 160 amp alt? im thinking about going up in size to that or the diesel 200 (gotta make sure it fits) and how much you pay for it? best i can find is 180 witch is pretty friggen cheep for a 160 amp alt... good move on going 1/0 piping on the battery cables... did you upgrade all the grounds as well? may sound tedious but you gotta remember if you add higher gauge at one end of the curcuit .. you should raise the other end... by no means should it need 1/0 gauge but it couldnt hurt to bring it up to 8 or 4 gauge... and theres ALOT of grounds hinding around that truck.. make sure you get em all... just a suggestion thats all



i have no idea what that triphase does nor what the hell it is... best assumtion would be a cheep manual timing adjustment

loss of performance even with your current mods would make me think of a stretched timing chain... best way to check is stick a timing light on it..if it anywhere near past TDC (- range) id accuse a t-chain... known for stretching due to the nylon coating that DC puts on them to keep them quite...

id seriously considerd chokin that exhaust up a bit... especialy on a 318... 2.25 is your ticket

 

I got alt from a web site address is http://www.motorcityreman.com/ thanks for the tip no the timing chain i will have to check that
