Thanks! do you have any pics of yours?
Shifts like a drag car, real firm and hard.

 

i have an engagement ring for sale. cheap. half karot(sp) i believe, sell cheap. looks great and helps you stay in the hunt for a charger. and helps me get a little closer to one as well. lol

 

i have lots of pics will upload them to somewhere and post a link.
installed a boost gauge today saw instant boost @ 6psi and above 4000rpm it will creep up to 7

has anyone installed a smaller pulley on the radix say 3" im trying to get it up to say 8 or 9 psi that would be the greatest is there an online place i could check out

 

Do you have the 3.4 pulley on it right now?? I have the 3.1" pulley from the 6.0 kit on the shelf. It would take the system to 9 lbs. Problem is, you can't get away with it on premium fuel. It seems that they start to detonate over 7 psi on pump gas. It would require race gas.

 

I see about 7 psi at first, and by 6000 it comes up to about 8.5. I had the 3.4 inch pulley on my 5.3. I never saw any KR or heard it either.

Mine was running pig rich though from the headers and maybe bad o2's.

 

yes i have the 3.4" pulley ...did more runs last night barely touched 7 psi @ 5500 RPM is that normal for the radix or should i be seeing more boost like Flyer

Ben thanks for the info looks like the 3.1 pulley is a bit too much..
i think ill leave the pulley alone truck is running so good rite now

 

7psi is EXACTLY what it should be running......

 

Try a 2.93 pulley, heck if a ford 5.4 can handle 20psi your should easily handle 10-12.

 

The Lightnings 5.4L (8.4:1) engine has over 1 point less compression than a LM7 5.3L (9.5:1). This allows the Lightning to handle more boost easier. Not only that, the 5.4L engine in the Lightning has a rotating assembly designed for higher cylinder pressures as well.

 

Can you do something with the heads to lower compression at least a half point?
