I am fixing to do an aftermarket cam on my magnacharged 5.3L, and was wondering how many rpms I can spin my 5.3L with the radix and still be building power? Also, what rpms are all you out there with a cammed radix shifting at?

 

i guess that depends on the cam you choose and if you upgrade the valvetrain

 

I have the 3.3 pulley on my 4.8. The engine has longtubes and the stock cam. It pulls really hard and makes about 10 psi...

 

Damn back from the dead, good to see you around.

 

radix 112? it can make some heat if you spin it too high too quick. Lose some timing due to the high IATs and end up losing some power and defeating your purpose. Track truck...don't go past ~6500 IMO if you get the right cam (don't forget springs) otherwise you'll have hardly any timing worth anything at the back end of the track.

Street...all kinds of possibilities in the radix's lower TQ areas.

 

What cam do you plan on using? What kind of power are you at now and what do you want?

 

Don't really have an exact cam picked out yet, but I am simply trying to figure out how many rpm's the mp112 makes good power to before it starts to fall off?
