which model is beter the d1 or the p1

 

D1 will bring boost in earlier.. But the P1 will make good hp also.. The d1 has different vanes(wheel in it)

 

how much boost can i see from a P1

 

depends on the pulley but also more than your truck can handle

 

That question is about as generic as it gets. How many cubes, what cam, what heads, intake, exhaust, what crank pulley, what blower pulley, and what rpm range are you looking to work with in?

 

i was just trying to get a all around answer of the max boost i will see out of that head unit

 

check out pg 42 on this guide

Unfortunately that question can't be answered with any degree of reliability without answering at least a few of those questions.

However if you want an answer...

I would imagine that the P1 would make about 2lbs of boost if it was running on a 900+cubic inch Sonney Leonard Motor with a 9" crank pulley and 3.5" blower pulley at 7500 rpm or about 40lbs of boost on my lawn mower just turning it by hand while the mower is running.

 

What size engine?? Cam??? Heads?? I figure that you are not trying to make crazy power so a P1-2 sould be more than enough for you

 

Just get the D1 and have room to grow. Ive got about 7lbs but huge pulley 4.75". My combo 5.3 stock heads 216/220 cam XR-1 dump.
