This is a lot of why I went procharger. Yes the roots blowers make some more torque down low, but if you consider how the transmission works on the street any blower is going to drive the same on the street. Get on a track with slicks or a dyno and you might see a small amount of difference, but I don't care about either of those scenarios. A 4th gear dyno pull is about as unrealistic as you can get with a 6 spd tranny. Either option will destroy tires when you want to, and pull on the top end when you want to. If anything, like you mentioned, all that low end torque puts unnecessary load on the motor when you aren't asking for it. Not that that's necessarily bad. There are no bad options to me, really.

I'm getting the P1X, which is basically the updated P1SC. They don't advertise it a lot for the trucks kits, but i talked to them and they recommended it. They are currently building my order, so that's where I am for now.

1st, a centrifugal and a PD blower drive completely different on the street. The PD will be instant down low where the other builds power linearly with rpm rise.
And you dyno in 4th with a 6R80 because that's the 1:1 gear. You don't dyno in overdrive gears.

Sorry, that was probably poorly worded on the iPad. I was just trying to point out that if you get into it, once you're at a place where the tires are somewhat hooking, the transmission is going to have you in a similar place and you're going to be hauling *** either way. Trying to compare "down low power" on a dyno pull in 4th gear is pointless because that situation is specifically set for the dyno (it has to be programmed to stay in one gear so long)!

In either case, we're driving around in trucks with no weight over the rear axle, so...

Yea, I hear people say they want the centrif because the gradual build in power will be less likely to spin the tires. I have to disagree. If you're putting 500 ftlb to the tire in a truck, it will spin, gradual or not.

I've owned a couple of both styles...I like the PD better for a daily driver. Plus the centrifugal hassles I mentioned earlier.

It's not totally truck related but my son has a procharger on his 2013 5.0 mustang. He has not had any belt slip, no thrown belt and no bent or flexing bracket. The kit came with a 6lb pulley but we're running a 10lb pulley. The car put 586hp to the rear wheels on a mustang dyno with headers, no cats and a Boss intake and runs 7:10s thru the 1/8, it's a 6spd with 3:73s and needs a gear change to 3:31s badly. Car is driven daily, street raced some and gets beat on sometimes all with no problems whatsoever.

The whipple kit is kind of hard to beat on these, simply because it makes a boat load of power, has an 'OEM' like tune, and is just an easy to use package.

But the procharger is more for a hardcore guy, IMO. You need to know what your doing more so than a PD. Its not point and click, in any vehicle, where as the PD is easier to use. Press gas, and go. A lot of people like that.

I think you are going to enjoy the procharger.

As far as problems, you shouldnt have very many issues with a modern centrif setup, and lets not act like PD blowers arent NOTORIOUS for belt slip and shredding belts. The automatic and lower boost levels might prevent most of that on the truck kits, but in general...

I'm considering the D-1X Procharger from Oz Tuning. Flows up to 1500 CFM, and up to 1,000Hp. Just in case I decide to get crazy with it later.

E85 with that setup and you'd have one badass hotrod truck for sure

That couldn't be farther from the truth. Put the Whipple and the Procharger on two identical trucks, set both for 10 lbs of boost and the Whipple will smoke the Procharger every time. PD blowers simply make more torque lower in the RPM band - that definitely changes how the truck performs, on the street and at the track or dyno.

You don't get "all that low end torque" unless you have your foot in it. If you drive the truck without getting into boost there is ZERO additional load on the engine created by a PD blower. You don't get into boost unless you are pressing the pedal pretty hard, which would indicate that you are in a situation that requires more power.

To try and put this PD blower / engine stress fallacy to rest, spend a few minutes researching where they came from. Before turbo diesels were developed and perfected for big trucks, most used PD blowers to make the power needed to move big loads. Ingenious hot rodders simply took the existing hardware and started putting them on their rides.
