killing the procharger?
you make it sound like procharger vs roots here is the difference between an ebay electric supercharger and a 4.2L whipple
Yes, do to the design of the two blowers the Whipple will make much more torque down low at the same peak boost levels. Because it makes a lot more boost down low. Did you see the power delivery of the two on the graphs you posted?
I see you didn't answer my question either. So I take it you don't know the peak boost numbers for those graphs or you don't want to say as it doesn't help push your Procharger agenda.
Comparing the graphs for specific numbers is silly when you don't know what either of those graphs represent. You don't know the fuel they were on, the peak boost numbers, timing at peak torque, timing at peak HP, if the graphs are STD or SAE, so on and so forth. The only thing those graphs are good for is the fact they show typical TQ & HP of each style blower.
We get it, you want him to buy a Procharger and that is what you are pushing. That is fine and dandy. But don't laugh at the fact that a whipple will make way more torque down low when compared to a Procharger. Because no one in their right mind will discount what torque the Whipple will make over a Centrifugal blower.
I have no hate for Centrifugal blowers. In many applications, they are the way to go. A DD truck isn't one of those applications that I would say they are ideal.
Also, I have known many street cars and race cars that had failed Prochargers. Most of those people said they would rather deal with Comcast than deal with Procharger. ProCharger owns has the large blower game. No doubt. Doesn't change the fact, that besides a bearing and seal rebuild, they will tell you to buy a new headunit. Standard procedure for them. All those people I know that had Prochargers, besides a couple of racers sponsored by them, now have turbo cars. Was an easy decision for them to cut ties and run. I guess you guy can just hope that he sells the truck before the thing fails.
