I`ve been reading everything from this group for about 2
months.Everyone seems to be very knowledgeable.
This is my first post.
I bought an 2004 GMC 2500 HD 6.0 last July.I just can`t seem to leave
anything alone.So I started adding performance parts to it.My
Brother-in-law works at an auto parts store,so I get everything at his
cost.Which is extremely cheap.
All the parts were in stalled by myself.
Cold Air Intake
2-1/2 in. Cat Back
1-5/8 in. Headers
Underdrive Pulleys (crank,alt)
Got pressured into taking it to the track.
Best E.T. was 14.886 @ 88.564mph
I think the mph was down cuz it weighs a ton,and it's like driving a
brick into the wind.
I know the stock set-up is 300 hp,but can anyone take a good guess how
much power I`m making now?
I wish I knew what stock e.t`s were.
Sorry so long for my first post.
