OH-MAN

My AZLOC bros stopped by sunday and sweated their butts off installing my KB, 255 fuel pumps, filter, and plugs.
It was only 112 and not much humidity
Have not been on it hard yet as it is a bit lean, Tune is on friday. Can't wait to get the 60 lbers in and the bigger MAF to compliment the KB.

those kb's kick are some kick *** blowers. Good luck w/everything.

I have ridden in a kb cobra and damn what a diff from the stocker you are a lucky man.

How much boost can you run on that engine assuming its stock. Correct me if im wrong, but cant the cobra guys run more boost that the L guys because of stronger internals.

I've *heard* of some guys claiming 18+ on stock rods, and if it's true, imho they're playin with a time bomb. Most guys can run 14-15 lbs and still be relatively safe. And yes, the Cobra's come with forged internals, we have ( and this is still in debate, but I'm goin with what I believe) steel cranks and forged pistons, but we've got powder rods. Snap like a twig.

BeefTip

ok, I was pretty sure that there was some difference.

damn this makes me want a lightning, ive always loved those trucks

The boost can usually be around 14-15 #'s on a stock motor and be "ok". It's all relative to the power the truck makes, elevation, climate, ect. Around 450-500 rwhp the rods usually crap out. All Lightning's have forged pistons and cranks but, the rods are JUNK. As a matter of fact, all 5.4's have forged steel cranks from Ford, unless they were a reman'd engine. They wil have a cast crank then. The 03-04 Cobra's have forged internals and I have personally seen them make 700+ rwhp on stock heads, motor.

yeah ive seen those cobras make some insane numbers.

a KB and some nitrous!
