what are the s/c companies out there with current v6 s/cs ... also what are their gains on a stock block and max potentials on an internally rebuilt 4.0

chrisc

now much engine work has been done on the 4.0 considering that there are not many companies who make them. the only ones off the top of my head are the procharger w/ SSM heads and cams, it made 440rwhp. also, the vortech w/ powerhouse heads and cams made numbers in the high 300s or low 400s. Most people who have engine work cant really max out their systems because the tranny's give out at around 400

as for non-worked on engines, there are the general gains:
procharger: 330rwhp
vortech h/o: 320rwhp
vortech: 260rwhp
xcharger: 250rwhp
xcharger h/o: 298rwhp (i think one one person broke 300, lol....its weird, a lot of people end up with 298 or something)

say we have a built 4.0, with new tranny and d/s, intercooled procharger system with new heads and cams... is 500 horses a possibility from this?

petepete

Yes

how much further can we go?

chrisc

hmmm, well the block seems strong, so i am guessing if you do better pistons and rods you can push it even harder. i really dont know, 500+ lol

with a built block and tranny you will need a TON of power to break anything (assuming you replaced the rear end and everything). The block itself is going to be very strong. It's an iron block with a closed deck so you could probably take it into the high 3 digits with the right internals and crank.

we already have forged rods right? or did i dream that haha... we would need new pistons, injectors, valves?, tranny, d/s, and rear end... plus the suspension to keep her on the road right
