Oh as far as proof as soon as I can get the printout scanned I will post it as well. Then I will also post my new numbers with the headers and programmer added in.

 

Stock exhaust is horrible on the 5.9... I think it's the same as on the 3.9 really. It's just choked.

 

when they tested that r/t it came from the factory with a **** tranny and they couldnt get a better one on such short notice so they tested with it anyways and the **** tranny put out out **** power

i read about it before

 

That sounds about right...I couldn't imagine that a stock R/T only puts 150 to the wheels. I am not a truck guy but I joined the site b/c I have a buddy on here and I am a car(well I guess all vehicles really) enthusiast. Hope no one minds me posting on this forum.

 

I saw that article, and it was total crap. 153rwhp on a Dakota R/T is beyond rediculous, my 03 R/T bone stock on heavy 20's dyno'd 213rwhp and 298rwtq.

 

we dont mind, welcome to DF by the way



SinCity R/T 213hp @ the wheels sounds about right thats aproximatly a 15% loss with is normal

 

Yeah, that sounds much better. The mag must have had a bad one, perhaps a clogged cat or faulty O2 or MAF or something.

 

okay so a 15% loss is normal, is that pretty much for all trucks????

 

Actually closer to 20% is the norm for a 2WD Automatic transmission truck, 15-18% for 2WD manual transmission, and 25-30% for 4WD automatic.

 

okay next question then, for the 3.9 with the 40 series, intake, and a TB spacer how much should the average motor gain from those mods? Because if I put my horse at 185 and do the 20% loss then i come damn close to my numbers that I ran at the dyno, but thats only 10 hp over stock? Im confused [:@]
