I know it wont deliver, my buddie put one on a built 6.0 motor with the smallest pully he wasnt seeing boost till 3k. the compressor is too small to keep up with that big of a motor. Id look into a turbo, procharger or nos.

 

I would bet he had problems unrelated to the blower.

 

no not at all he put a f1 procharger on it and the truck hauls ***.

 

at 6.0 L the radix should be just fine. what pulley was he using? as far as I know the 2.75" is the smallest pulley and 18,000rpm the limit of the blower.

 

I am eventually goin to put a fast intake on it with an F1. I do have nitrous on it already. I think I am just going to get a 2.7 pulley made for it and see what it does. If Im not happy with the results then I will just have to go ahead and get the F1.

 

There are a bunch of lightning guys that spin their eaton M112's to 18,000 rpm fine, but I would stick somewhere between 16,000 and 17,000 just to be safe. 14,000 is definately on the "safe" side.

 

18,000 should be safe and reliable.

 

Is anyone on here running a 2.7 pulley on their Radix? I just got mine in and was wondering how much boost you were seeing with it. I have a 3.0 on mine now and am only seeing about 8 1/2 psi. 9psi when its cold outside and with a 50 shot going through it.

 

blownchevy was running a 2.8.....

 

Well nevermind I decided today that Im just goin to go ahead and sell it and get the F1.
