So I guess its narrowed down to D1SC and 2.9 Whipple.

 

and then that will depend on the amount of money you want to spend, and whether you want to restall as well.

 

The Whipple would like a tighter converter but it will work with what you have, just not nearly as well.

The Procharger would be the most logical choice.

 

Im just a fan of a pd blower in a heavy vehicle. Mine loaded up as my daily weighs 5600-6000 most days and it is very enjoyable to drive with a stock converter that will flash close to 25-2600 and stall at 3k but I do have a 6spd. It will toast the tires in 2wd even loaded if I nail it. Gorske has a pc and I think a 34-36 converter and hes very happy with his setup and its a runner! Just a different feel and coupling. The pc does have more top end hp potential in the end and the pd has torque from idle to well beyond normal driving shift points. I had a rear mount with a loose converter on another truck and response was great when Id hit it but hated the lazy feel just driving around. That is why I went pd even though its much slower with my stock setup so far. A cam would fix that. Dont think there is a bad choice just preference and $$.

 

preference and money is exactly it, and on the used market I think the prices are pretty similar even.

Ive had 2 ProChargers on my truck. Next blower is the LSA. I want torque.

 

D1-X more efficient the a P series blower with a 4" pulley will be around 8-9 PSI and all the fun you can handle with that much gear and that much converter.

 

Moot point atm since he can't keep it running.
