we might want to keep an eye on this thread and see what comes of it:

Yeah had run accross that post last night. Have it marked for followup to see if anything comes of the injector observations, also confirms the general thoughts I had about the radix tune, weak timing and rich A/F. I suspected such when I changed to smaller pulley and saw little to no KR in my logs.

 

I ran 10 PSI on the 6.0 in my RCSB and NEVER ran out of injector.

 

My injectors are good .. 3.1 pulley on mine.

Brian, what pulley were you running on the 6? Boost is a relative term, cause there's lots of variables in there. The pulley size is more predective for fuel usage, since we know it's pumping the same amount of air with that pulley at a given rpm with the same pulley but different boost. That confuse anyone?

 

haha nope.. boost is just a measure of resistance.. not a measure of flow

 

2.8 if I remember right

 

I will say i spoke with brian today and he was an oustanding amount of help. hopefully we'll get these issue's worked out. we will be posting data logged numbers, wideband numbers, and track times. i think the radix on an SS with the 3.3 pulley that comes with it could run a 12.x which is what the guys with smaller pulleys have been running. thanx alot for your help brian, i'll keep ya'll up to date.

 

You're just gonna leave it hanging there ... ???

I don't really think just the RADIX is good for 12's.

 

Well we went 13.6@98 this weekend with a overwieght SS. It had the sub box stil in it with a heavy tanoe cover. All it had was the Radix with a 3.3", Tr6's, trailblazer converter, shift kit and servos, and Zippy's tune. Thats it! stock airbox(with a little cut) Bone stock exhaust from the manifolds back. At standerd race wight with little fuel a 12.x would be attainable with good air.

 

Remember when they said it could not run 11's either

There are a few guys that are in the low 13's with a Radix and the SS, nothing more than spending some time with the calibration.
