D1sc Quesitons?
D1sc Quesitons? How much boost can a D1SC push out on a 346? What RPM and what pulley size will max one out? I am looking to build a forged 346 and make around 600RWHP with ported 6.0 heads and somewhere around a 9.0-9.5:1 compression. I'm looking to do the ultimate budget LS1 build up because I am poor and still need to have a stupid fast car. I figure 600 should be pretty easy to make with forged internals right? I have seen a few around 700rwhp and I am pretty sure KP makes that or more.

I was running 6 psi on a stock bottomend 346 and made 600rwhp!!! The D1SC will support 800+rwhp on a 383 stroker so I'm sure you can get 720-740rwhp on a 346 with all the supporting mods!!! EPP seems to do it all the time...so I would shoot them a PM or check out there web site!!!

Over 700 rwhp on a Mustang Chassis Dyno, which uses eddy current would be approx 750 rwhp on a DynoJet Chassis Dyno! Considering some of this horsepower is used up through the IRS rear-end, this is really impressive! All out of just 346 cubic inches!

717 rwhp and 717 ft lbs of torque - On a Mustang Chassis Dyno to boot! This would be well over 800 hp at the engine!

Thanks exotic performance. I was looking to build mine almost exactly like that. Maybe a little more cam but those exact same heads!! Awsome build ups, I hope mine turns out as nice as those did.
Pulley sizes are determined by what components you have on your engine, along with your altitude. Generally speaking, with what i see that you have, a 3.70" pulley is going to be about right with a D-1SC for a 6200 to 6500 rpm range. Bob
