Has anyone tested and compared results over the standard P1/D1?

I have the D1 and it works killer not sure how a D1x can improve anything

Patriot Six

Detoxx did a comparison. The D1X only picked up power above 6k rpms. It needs to be spun harder. If your goal is 850whp or less, the D1 is the way to go.

Thanks
Maybe a P1x and best of both worlds low end and more top end

I ran a 10.3@141
Just 3 mods ..9 ish boost need to get it to launch quicker

Patriot Six

Haven't seen any results on the P1X, but it moves less air (1275 cfm) than the D1. Hard to beat the D1, especially for a street car. Just turn it up and you'll be in the 9s.

I did a swap. With the same pulley it picked up 52whp but then the clutch started to slip a little. My triple disc went in today so once it's broken in we will try again to see what it makes and then pulley down for final results.

I'm having trouble posting pictures lately but I have a graph of the comparison so far you can see if you click the link in my signature.

With the D1X I did 636 rwhp (Mustang Dyno) on stock bottom LS1 and 4.25" pulley

Can't pick up 52 hp without more boost unless the supercharger magically has no losses.

2 psi with the same pulley and it flows more in the higher rpm range too. Raised limited from 6900 to 7200.
