What boost do most of you run on the street?
#16
Here are some links to some information on Headers and How they work.
I hate to come off like a jerk....(actually, I don't care if I do)...but expecting a seat of the pants improvement from bolting on headers is not realistic at all.
Do a reality check folks. If every mod you bolted on gave you a raw H.P./Tq. gain in the exact same spot on your power curve, you could have a 600 H.P. truck for about 3000 bucks. It doesn't work that way. All the crap added together is what makes an 11 second truck. Leave parts out with the knowledge that the guy in the lane next to you did that part of the equation and is about to beat you to the end of the track.

Check out the links before you start thinking you did the wrong move with the headers. You will realize that the headers are a piece of the whole puzzle for a quick truck.
Rocks

2001 Black Lightning
JDM chip (J69),JL 4# lower, metco 2# upper, Magnaflow 12468, Denso IT24's, Line mod valve, breather cap, 160 deg. stat.,LFP elec. fan,Cobra R w/pump, ported/polished heads and intake, ARP head studs, Helicoiled sparkplug holes, BilletFlow T/B, Nitto 555R's, Dynatech Long Tubes-cats and mid pipes, 2" drop shackles, Cervini Ram Air hood, "Lightning" floormats, Saddleman soft tonneau cover, Royal purple fluids.
My Lightning is not a daily driver, so Im thinking the 6# lower wont hurt, might need a reburn though!

of your motor, with that said BOOST WISE you are close to what most will say is the safety limit on the factory rods. HP wise it'll take more, but be careful with the boost, especially with an Eaton, at some point the heat of the extra boost will actually work against you and make you slower in some situations.
However you can get away with the 6 lower and 1-2 upper WITH THE CORRECT TUNE.
I run 4 lower, 2 upper, Mother of all Ported Eaton, JLP Cool Air, and see ALOT of boost VERY FAST. 10lbs @ 1/8 - 1/4 pedal, and over 15 at WOT. (oh ya, cant forget the 75HP of Juice too) WOO HOO...........
BTW
YOU NEED COLDER PLUGS IMO

Rob-I havent built the bottom end yet. Its next. As far as colder plugs go, I think the IT24's are about as cold as you can get.
If Im not wrong, the 22's are a little hotter,and the 20's even more so. What plugs are you running? I had the TR6's in but switched to Denso's.
Thanks for the help!!

I have to agree that it's a needed piece of the puzzle as we build, mine showed a increase in both HP & Tq, it was a little quicker into the HP & Tq (a few hundred rpms), and carried higher in the rpms (also only a few hundred rpms) although Peak may not be the biggest bang for the buck, it improved overall,and should continue to help w/future mods.

YIKES
IT24's are 1 zone colder (equal to NGK TR-6's)
With your Boost level Denso IT-22's or NGK BR7's
would be safer (thats 2 zones colder than stock), I run 22's
even in the winter with just 4lbs of extra pulley. With the power level we are at, any safety we can add into our tune IS A GOOD THING, hehehehehe.............

the reason you loose a little bit with headers is due to the loss of backpressure
if you arent making 500 at the ground you dont need the headers
the stock system is very very good
i would spend that money on other things to make you truck go fast at least till you get to the point where it is needed to go bigger on the exhaust but right off the bat you dont need it. it will just work against you at first till you get the power levels up to take advantage of them
