hey ive been wanting to do something to my truck performance wise but have no idea what where or how would be he best way to approach this situation.

any place i should start specifically about the only thing i know performance wise is a cold air intake.

 

CAI's are a joke
i bet others will explain more on this later but basically bolt on cone filter intakes suck in air from your engine bay....have you ever opened your hood after driving for a few minutes? its not cold
unless you build an intake that sucks air from outside the engine bay (fender well, grill, hood scoop)...you'll be sucking in hot air and hot air is bad for performance.

start with underdrive pulleys or a drop in filter ( k&N)

you'll see minor gains with those just to get your feet wet....

 

the engine bay is still hot with out a cai....adding one doesnt make your intake suck in hot air.... its going to either way. besides the facotry box is restrictive as hell... adding the cai increases the flow of air into the intake, its not much of a gian but it helps. also adds throttle resopnce

 

Well Walter , after looking at your profile , you have a '98 3.0 .
Don't expect to make it a "Super Truck".
3.0's are reliable , when taken care of , but don't expect high performance.
About the only best mods you can do is an underdrive pulley setup like Stig said.
Is this your DD (daily driver) ?

 

yes its a daily driver but i dont go many places but my local town and school no crazy road tripping for me.

i have the truck and just got the whole thing running tight after a few things going wrong (bad alternator spark plug wires some odds and ends, brand new everything for brakes) but now im just lookig to do something in general to take up time. Love the truck to death but i see so many people with so much done to theirs and just want to get down and dirty and do something with it. problem is i mostly know how to fix cars and trucks not enhance them.

so about these underdrive pulleys i did some research and apparently they mess with a/c and some other things but in general what are they supposed to do? im not trying to do something crippling for a few more horsepower.

 

in order of performance gain:
1. programmer (superchips, jetchips, bamachips) will run you between $100.0-$200.0 (used) / $300.00-$400.0 (new)
2. underdrive pulleys
3. E-fan (electric fan)
4. larger air intake

for my intake, I used the stock intake box, but removed all the guts as well as the port from behind the headlamp. blocked it off from the rest of the engine bay so it is only sucking air in that comes from outside. also I built something that will direct the incoming air right at the cone filter. sort of making it a short ram intake, but not quite.

 

Good idea on the intake i might have to mod mine like that.

 

This was a post (may have been on TRS) on a good test
for aftermarket intakes / filters:

I don't know how many of you caught this post in the link I posted, but the test this guy did is pretty conclusive test that the OEM intake and paper filter IS NOT the limiting factor for airflow into the engine, and you won't get any more airflow with the K&N. And on top of that, it's with a GM product!!!:icon_rofl:


"Only way to really know is to read your Mass Airflow Sensor on a scanner with both filters. Take a WOT run and record the highest MAF reading, then swap filters and go for another run. If there's a considerably higher reading with the K&N, then your engine is outflowing the paper filter. If they're similar, then the engine is not making any more power with one vs. another, no matter what your "butt dyno" is telling you.

Sometimes the K&N filters make the airbox louder, but really aren't doing anything else. People tend to equate more noise with more power lots of times too.

On my old '97 Grand Prix, I saw MAF readings of 19.8#/min with a new Wix paper filter, a K&N drop-in filter, an open cone, and an aftermarket CAI. This tells me that the engine was breathing just as well thru a paper filter as it was thru any other filter I tried. The paper filter and factory airbox were of sufficient flow rates for this engine."

 

fail

 

how so. my mpg went up....

 

Mine did too

 

ditto for me.

 

If you're even remotely interested in building up your 3.0 V6 I suggest checking this site out.

 

My 3.0 went up from 244 avg a tank to 266 avg a tank from a volant cai.

 

you can also get roller rockers too

 

Im glad you mentioned that, I was going to if someone hadnt. This man's site (Tom Morana) holds the key to unlocking 3.0 full potential. But its costly. I have a K&n and can say it took me from 15 MPG in the winter to 17 MPG. So I know the CAI's have a bit of influence.

 

I did this a long time ago and my truck still hasn't blown up. It uses the stock air box.
RIDING ARIZONA - MORE
I also have the UD crank pulley and a tuner.

 

My attainable list:
UD Pulleys - DONE
Screamin Deamon Coil Pack - DONE
MAF MOD - DONE
Roller Rockers
Escape throttle body
JBA Headers

Dream list:
3.4L Stroker kit
Whipple

 

No tuner?

 

I think the noise of the added CAI System caused everyone to take their foot out of the throttle a little and then the mpg’s went up.

Adding CAI without a corresponding header and valve timing changes usually adds only more noise and in turn the sense of going faster or more power.

 

the only change to my driving style comes from if my 4 yr old is with me or not.

 

About how much HP have you gained from doing all of this? Also, what is this MAF mod I keep seeing, but can't find anything on what it is, or how to do it. I've searched, and still have found nothing, can you guys help me out?

 

Of course its going to go up you're burning less fuel because your engine is retarding the timing.

 

Because that's a real Cold Air Intake
