Hey anyone have any suggestions for some performance upgrades on my 4.2L V6 engine for under $400.

 

A superchip and intake would hop up your truck for just a little over $400

 

Get a Superchip and a K&N (K&N cheaper than an Intake) and shift kit!

 

chip, and if your straped for cash get a k&n and do a poorboy fipk

 

ok... here is what you do and you will get GREAT performance.
[list=1][*]Superchip - $235 Shipped - 20BHP (real #'s)[*]K&N Filter w/ Airbox mod - $49.95 - 5-7BHP[*]29 1/2" Cherry bomb Glasspack w/ 2 exhaust clamps - $20 - 8RWHP (cut stock muffler and bolt this muffler on... available only at PepBoys)[/list=1]

Total: $305
33-38BHP

The sound is decent for the glasspack with a loud low rumble but a little quiter rev. When I had mine, the glasspack by itself add 8RWHP. This is the basic and best bang for your buck mods and will bring your 4.2L V6 from a stock 205BHP to ~240-245BHP. This is my fact and may not be others fact!

How much louder is the Cherry bomb Glasspack ? I just saw one at pepboys for cheap and Iam not sure if its worth the $20 Will my truck be a lot louder?

 

well, lately i've been removing my cats and have been dumping just straight headers... just on the weekends tho. and during the week, i have the cats on with it dumping right after the y connection... so I'm pretty used to the loudness... yesterday i added 30" of straight pipe and put my 6" turndown on.... this makes it very quiet to me. i can bolt on any 3 of my choice from loudest to quietest, straight pipe, flowmaster 40 (2 chamber), and then the glasspack.

i bolted on the glasspack and to me it sounds like a stock muffler with a low rumble growl thats real quiet. at pepboys it's only $14.95 so if you don't like it your not out that much money. I don't like my flowmaster 40 and that puts me out $75!!!. I'm going to dyno the the three options i have to see what puts me where. then which ever gets me the most... i will then dyno the airaid vs. K&N w/ airbox mod.

 

Thanks for the information. I think I will wait for a while and grab a gibson. As you know V6 F150s are quiet stock and I want mine to sound like a V8.

 

then go buy a v8. the glasspack is the only thing that makes the v6 sounds like a v8... ESpecially at idle. the glasspack has the loudes idle of all. remember... i'm used to straight headers without cats and cats w/ dumped right after y pipe. the glasspack is a great buy, but i want the loudest setup possible, so i go headers!

 

With my setup(dual in dual out flowmaster with dumps) my truck sounds very much like a very lightly modified 5 liter with say dynomax mufflers or most like a stock 4 valver 4.6. I think a lot of it has to do with my intake mods as well as the extra timing my chip has dialed in. I lowered my idle speed 200 RPMS(with no MIL suprise!) and Ihave to admit my truck sounds like a million bucks, I was expecting the raunchy V6 sound but all through the range it sounds very nice and when I get on it it howls like a whipped dog, only a lot meaner...I've also noticed that this thing revs like it has a lightened crang/flywheel/clutch, it truly sounds MEAN. The only thing that I think it sounds most alike would have to be a DOHC mod motor.(except of course when you slap I nice set of mufflers on the DOHC and then they just sound terrifying)
