supercharger or turbo for better numbers at the 1/4 ????

 

There are a lot of variables here. I would have to say the turbo will net you the best ET at the track.

My consideration would be between the Livernois turbo and the radix.

 

What no love for the STS kit?????? I have yet to see someone be dissapointed by this kit. It added about 100rwhp and over 100rwt over what my radix did.

 

I would say turbo, and I have a supercharger.

 

This is going to get ugly. Keep it clean gentlemen.


My opinion is that is a loaded question. Too many variables. Be more specific. Are we talking a Radix or a centrifi? Are both trucks identical, because each truck will like a different stall based off of the type of FI. Plus different bolt ons will have different effects as well. What about cams?

 

ok on a 4.8 scsb 2005 automatic with no bolt ons yet o its a silverado

 

any time you can deliver power to the ground all the way though the power band, the better the et will be.

6 psi of Turbo/centrifugal against 6 psi of Radix......On the dyno and the track, I would put my money on the Radix.

 

Totally stock truck...I'd say the Radix. The centrifi and turbo would most likely need a stall to compete. There's other factors though, like elevation and a properly sized turbo. Not much has been seen for the Livernois kit, but I'd bet it'd be close. I know here, turbo's tend to perform better than superchargers. They're not as affected by the high DA's we get here.

A better question might be which one would net the best mph. That's a function of the overall power. The ET mostly comes from traction and chassis setup.

 

I have seen some wild "Radix Supercharged" vehicles (2002 Z06) around here before Carlsbad closed down. I will have to travel to find a new track now.

 

Turbo will have less parasitic loss. Regardless of what the loss is at cruising speed, under boost superchargers use more power. A properly sized turbo on similar boost as a radix or centrifugal will be faster. If the turbo is too large and spool time is long, that is a different story. Just talking 1/4 mile times like you asked, you are only in the low end for a short time and as long as the turbo is sized right you should be good on the low end. Even my D1 would build around 2 psi with a TB stall, I would imagine a small to mid sized turbo would do better.
