ATI with stall or Radix?

I want to know if anyone has any dyno numbers a D1sc made with a 5.3. I talked to procharger about 2 weeks ago and I told them my setup with the cam. They recommended the D1 over the P1, but they told me that 400 rwhp would be easy to make without my cam with the P1! I want to beat a Lightning truck in my area that runs 8 seconds flat in the 1/8th

I have also looked at the turbo setups, C Motorsports is good but no price, Livernois price is insane, I agree if alot of power is what you want to make the turbo is the way to go. The STS is a awesome kit, but I dont want to mess with the meth injection and upgrades on turbos, to make the same amount of boost you can get with a centrifical.

The D1SC has to have the oil changed every so often whereas the Radix does not. Traction may be a problem with the ATI with that sudden kick in boost.
I am no expert, nor do I play one on TV.

With a Radix, full boost kicks in as soon as you step on it.

It is my opinion and experience that the Procharger truck kit is limited to right around 530 to 540rwhp max. At around 500rwhp, the belt becomes a problem. GMCSKI and I had both had a D-1SC (which uses a larger pulley than the P-1SC), at 500rwhp both of us had this problem. A decent stall is also needed. The Prochrager also has to be tuned alot. For all out power the Procharger is the one to buy.
I would buy the Radix.
