Stock Air Flow Numbers and Mod

Nice stance with the 38's !

im am running a purolator (i think) filter, flowmaster muffler with duals, and the ASP pulley kit. I've never cleaned my MAF, so its a good idea that i should do it, I'll work on that today!

How do you like your pulley kit? Notice any freer revving after you installed it?

I like it, you can tell there is a little more power with it installed

Any problems with the headlights going dim when you stop for a red light?

How about the power steering and air conditioning?

The flowmaster with duals will scavenge your cylinders a little more causing some vacuum to develop. A standard filter like the purolator will also keep the vacuum up. Try a free flowing filter like a K&N or if you are opposed to that, one of those fram "air hogs" should flow better than the stock style one. The air box mod will have much less impact if there is a filter restriction.

You are very welcome, I hope the info is helpful and an deliver similar results for others.

here are some pics of what i did, so far its working well and i am noticing a slight increase in mpg and power, but i would like to do a little bit more driving and testing before i confirm these statements.

Looks good, probably cheaper than the rad hose route too !

[Burger Steak & Eggs]

Mine looks similar also, except I used two black plastic fittings on the air cleaner and rad support, and the hose is a 2" fiberglass piece normally used in air cleaner snorkel preheater applications. Can't wait to see if it helped ETs.

Soon after I did the mod, one of the other dudes at work couldn't wait to see it. After he had a look, he couldn't resist doing the same to one of the company trucks.

[apimpdad]

yes, it was like $5 to do it all with pvc fittings, all were 1 1/4". I already had the silicone and the pipe at my house, so that made it even cheaper. Since the pics i have added a mesh screen that goes over the intake part, to keep bugs and larger stuff out.

I finally got some time to run it down the track. I am now running 15.0 which is three tenths quicker.

WOW this is what I've been looking for for four years! A mod with scientific data to back it up. Thank you.

What year and model of truck is yours ? ( ie 4x4,regular cab etc.) and what have you done for mods besides the air box one ?

Thanks
