Procharger D1sc
 

anyone running a D1 and if so what size pulley do you have and what boost numbers are you seeing?

just trying to figure out the size pulley i need for about 18-20lbs of boost :)

I run a 3.4 and see about 13lbs. D1SC.

i got an 8 rib setup with a 10% overdrive crank pulley (Innovators west) and i've ordered a RR 3.0 pulley and i'm hoping that will be enough to see 20's.. =/

that seems low boost for that pulley. i am on a p1-sc and with a 3.2 pulley see 15psi. i thought the D1-sc saw more boost on the same size pulley. cause if that is right you would have to go .7 down to 2.7 pulley to see 20lbs.

The D1SC is a little bit more efficient, makes more boost at low RPMs, and can be spun faster without extreme heat.

i think i'll hit my goal on the 3.0 pulley i'm just trying to get mid 600 hp really.

i'm currently looking at blower cams, maybe AFM but i can't decide really

i know that's why i was sayin.

with the same size pulley the D1-sc should make more boost. or a bigger pulley to make the same boost.

I see over 13lbs on the 3.4. Slippage maybe? You will need a 2.8 to see 20lbs on a D1SC.
Usually the 3.2 on a P1SC is good for 13lbs not 15. Are you using a power pipe or spinning it faster than 6k?

they dont make a powerpipe for v6's and the pull was to 6k. made 15psi by about 5700rpm's.

are kits come with a 3.6 pulley which is 11psi kit.
