twin screw VS roots VS centrifugal superchargers VS turbo chargers

[truckguy82]

Horsepower is an arbitrary number for the purposes of transmission power handling but in acceleration torque is the arbitrary number.

 

HP=TQ x RPM / 5252

Ftfy, just incase someone read that and thought hp in general was irrelevant. Torque > hp arguement is a pet peave of mine lol

Could go the best of all worlds and run a centrifugal, but I might be biased.

I have a question. Would a centrifugal supercharger be easier on a daily driven drivetrain since the full boost comes on mid range instead of all at once in the lower rpms like a roots style? I know this may be a silly question, but I'm relatively new to this and I'm more concerned with long term reliability than total all out performance. Just trying to learn all I can. Thanks.

I can make my centri tune act how I want below 4k rpm regardless. The thing about the Gen V is that you can actually control the throttle in a way that allows you to dictate where the power comes on. Not to say that you can't do that with a turbo or a roots style blower but the linearity of something like a centrifugal blower allows combined with this ECU allows me to literally say that I only want 200 ft/lbs of torque from 1500-3000 rpms in any gear and if it tries to exceed what I want the ECU will dial back the throttle in response which in return will result in the blower venting pressure to keep power in check. That is one of the major benefits of having all of your boost pre-throttle body on this setup. I have way more control over my power curve than a turbo or a roots style SC and I have a lot more potential to make serious horsepower if I want to compared to the majority of the other kits out there. A Maggie is going to make more power in the bottom of the power band but it is going to struggle to make the top end power that a centri or a turbo can make and with a good centrifugal SC you are going to have less issues with IAT on the higher end of the boost curve.

Damn never thought of powerband tuning via electronic throttle, thats a good idea

Thank you for the detailed answer. That's hard to get a lot online. What you stated is one of the big reasons I'm leaning towards a procharger because I can have the truck tuned so I can have a better balance of power, and reliability.

With the torque demand model that the new ECU's run it gives you so many options when it comes to dialing in your power band. It literally makes the early Gen IV setups look like the stone age. Once you have fuel and spark dialed in you can go back and fine tune your actual power output, having issues with keeping traction at 5500rpm while shifting from first to second? You can dial actual torque out just in that range until you are able to just lay into the throttle and let the ECU control the rest.
