Default What will max out a D1-SC?

I'm curious what it takes to max out a D1-SC, and what specifically will max it out? For example, is it simply that the head-unit won't flow anymore CFM? What would it take to max one out before needing to go to F1-A or bigger? Max PSI on a D1-SC etc.? I'd appreciate any input. Thanks!

"Maxing it out" refers to using pullies that allow the unit to spin to its highest RPM (as recommended by ATI). At that point its giving all its got.

Max PSI is dependent on your motor as boost is simply a measure of restriction. What makes 10 psi on a stock motor might make 6 psi on better motor.

They are telling me 62000 RPM is the limit of the D1-SC but couldn't tell me much more. I assume dampener size falls into affect as well.

Yup. Someone posted an excel worksheet that makes this really easy to figure out. You put in the blower/dampner sizes and it tells you what RPM the blower is at depending on the engine rpm. I'll see if I can find the link..

We got 16 psi out of a D-1SC on a 402 with AFR 225 heads, we were surprised and we made 757 rwhp on my Mustang Chassis Dyno. You can check it out here. http://www.exoticperformanceplus.com...Car.php?car=42

What makes 16 psi here in Indiana may only make 10 psi up in Denver. There are a lot of variables involved. Bob

Up here we do make less boost than sea level, but it is normally not that much of a difference. At lower boost levels, the difference is not too bad. If a setup is making 7 psi at seal level, here at 5800' most people see between 5 to 6. Setups making 14 to 15 psi, will see between 10 to 11 psi here. The thin air really sucks, but everyone is affected so it levels out everything
