I was looking around the thread and I didn't see anyone mention this. If this is a duplicate post feel free to lmk and ill take it down. I thought the numbers were good for stock components besides blower. Only 11lbs!

All these videos have given me YTADHD. Too much chatter. Oh well. Plus I'm not familiar with their products so I don't know what to compare them to.

That's so cool. I just bought a GT Premium last month and I'm going to get the super charger put on it by the dealer. I would be very happy with that!

Graph looks very similar to the Vortech set up, no torque and the power comes on only with rpm, over 6000 rpm.

Are you looking at the same video? If what you say is true, the graph would look much like the "stock" line...even keel until about 5,000 where it would shoot up to the 720+ HP. Instead, the graph shows a very steady progression. It's true that the car picks up at about 3,000 RPM. But that's how these care are designed and part of what makes them so great. You can use it as a daily driver and not be playing speed racer all day every day, but the power is there when you step on it.

I mean, that's how a Whipple/Roush work as well. Bypass valve lets the boost out during normal driving so it's not going to make power until you step on it. The only real difference is you can step on it at any RPM.

There is a Whipple/Centrifugal chart here somewhere comparing two graphs for forced induction Coyotes with similar peak horsepower. I am not sure I can find it now.

Oh...so you were talking about THAT and not the dyno runs/graphs that were being shown in the video? Ok, that makes more sense to me now then. lol. I was thinking I missed something in the video big time!

The difference between the Centi and a PD blower is where the torque hits,

With PD blowers you get 90% of the torque as soon as you mash the gas pedal at 2500rpm.

Centri's build torque and hp with rpm which should make it easier to DD.

But even the centri will burn the rear tires off real quick if one doesn't learn to control that right foot.

I'm new to this stuff. Didn't realize there were two types. I did know the Whipple and Rousch superchargers were the displacement type, but hadn't seen any that were this 'centrifugal' type of configuration. Good to know! Thanks. I had kind of thought that this was the key difference between Superchargers and turbos...that particular RPM requirement for the boost. The more you know!

Whipple is twin screw, and Roush is root. Right now LMR is have a super sale on the Roush.

Well, this is not 100% true, either. Turbos are not tied to the engine speed like a centrifugal blower is. A lot of turbo engines have gobs of torque at extremely low rpm.
