So im in the process of building my new drivetrain. I currently have 171k miles on my 08 Ram 1500 5.7 Hemi. I was looking at getting an upgraded 400hp crate engine from summit and then get a procharger running 6psi. roughly im looking at 550 to 600 hp at the crank if Prochargers numbers are right. I have gotten a trans priced out for a stage 2 at $3700 or a stage 3 at $4100. the stage 3 can handle 400 whp while the stage 3 is 600 whp. going with the 20% loss through powertrain i believe ill be making 400 to 450 whp with my setup which is just over the stage 2. i would love some opinions and experiences from ppl who have done this before. Maybe im putting too much money out and there is a better way. with this build its around $15k with everything. thanks in advance. BTW im mechanically inclined but dont have knowledge on trucks so im learning as i go. sorry if this seems noobish.
