whats the specs on the 4.8? is it completly bone stock? no head studs rod bolts? cam?

 

bone stock.

 

if u ccan make 600 rwhp out of that it will throw everything ive learned so far out the window....

 

i feel prety hopefull it will hit 500rwhp. really dont know about 600rwhp

post up, what do you think it will do. keep in mind i am not stoping at any preset boost level. i am going to just turn it up till something gives or the motor gives some sign that there is no more power to be had. with 118octane fuel i think it will take some serious boost but we will see.

 

i think the power will taper off a little sooner than 5800 but youll make it clear past 500 rwhp if u make six. my LQ4 is going on the market. LOL

 

Parish when you reach max boost on 93 oct, play with it a little and line it out some, if it is no problem i would like a copy of the pcm if it does not blow.

 

there probably wont be enugh time to try too many things. going to shoot for 11.5-12.0 a/f ratio. since i am pushing the motor as it is i would like to play it somewhat safe on the a/f ratio.

i am tuning with an aftermarket pcm. my file wont do ya much good. i will have log files from efilive and from the aftermarket pcm so you can see what the timing and a/f ratio is for the diferent pulls.

 

I predict your 4.8 will

Not because I want it to, but because you won't know how much it can take unless you give it too much.

Oh yeah, I'll chip in a few bucks if you still need it.

 

Have you already done this ? Cant you get quarter mile times on the dyno as well?
I know it probably wont be exactly accurate but it could give us an estimation of what the truck might run in the quarter mile.

 

i think that the first thing to go internally will be a piston. That is what happened to me when mine went. Everything else seemed to be ok besides the number 5 pistion.
