just got off the dyno put the fast lsxrt manifold only, the mass we got for it would not read. the final numbers was 480 rwhp,waitn on money to do the 102 mm throttlebody and the 100mm mass air to do a real all 4 inch intake.really stoked it gained 30 plus hp just the manifold.ill post pics in a bit .

 

Damn thats impressive and this is on your LY6?

 

GREAT numbers

 

dont lie it only made 300 to the wheels lol just kidding... i was there watching the dyno pulls and all i can say is dam rick your truck is bad *** man great job on the build and its true 480 to the wheels. just dont let me catch you in bakes i might have to give the 6.0 an lm7 beating haha.

 

Was the manifold untouched? Those are great numbers for a simple mani swap

 

yup it was untouched i watched them pull it out of the box bolted his acc on and then tune it

 

 

yup straight from the box,34rwhp on my h/c setup,hopefully the throttle body (102mm) and 100mm mass air make a difference in a couple weeks($$$$$$$$).500 rwhp feels really possible now

 

Nice Rick! Those lsxrt's are impressive when they fit right..Did you get a good deal on it? I have been looking around..If you can,post some pics of your truck up

 

Very strong numbers now get to the track and set a new personal best
