3.1 intake question

[stellhornata]

if i were to replace an intake on a 3.1 what would i do with the air sensor on the air box??because i was thinking about just changing the filter to a k&n cone air filter.

Don't bother modifying the intake, the stock setup is just fine for a 3.1, just keep a clean paper filter in the airbox. The higher hp engines offered in these cars used the same airboxes, so they flow very adequately for a 3.1.

[stellhornata]

then what should i do about putting a little more power i to my ride?? I know its a 3.1 but hey its my ride and i wanna do sumthing with it (performance nuthung to insane) but sumthing nice.i dont wanna go mega ricer.

A tune-up(spark plugs, plug wires, fuel filter, etc.) would be a good place to start if you haven't done one in a long time. That could potentially gain you back a little performance and it will ensure you have a good starting point for more upgrades.

 

For more power, a chip from http://www.60degreeV6.com or an underdrive pulley for the crankshaft from FFP( http://www.fastfwdperformance.com/ ) would be a good start.

If you really wanted to, you could port/polish the intake manifold and/or TB, but you may be trading some low end torque for some midrange hp.

Heres my intake:

 

The sensor is mounted underneath and out of view right after the bend. I just drilled a hole in the tube and put gasket sealer around the sensor and used the factory clip. It works and I can feel the extra power from the filter.

"Feel"...haha! Take the car to a dyno and test each setup, you're in for a surprise if you think that hot air helps. I believe it was "Taylor" who dyno'd a cone filter setup, it gained maybe 4-5hp max, but took away 20ft-lbs or maybe more torque = that's a noticeable difference.

except i got cold air going to it. The tube is made of plastic so it resists heat and the heat sheild controls some of the heat. I also got ram air on my car which makes the filter get more outside cold air at a high velocity.

Looks good too! But Looks arent everything is it?

believe me from exp. 3.1 hate WAI (ram air or not)

Ditto.

 

I just gutted the airbox in my GP. Not sure if it made it that much faster, but it sure sounded mean. After I did it, I could outrun my buddy's 95 SL1 5-speed, and I couldn't do that before, so I guess it did help a little bit.

 

On the other hand, An open-element WAI kills what little performance a 3.1 has.

[Mach 5]

whatever guys. Say what you like. All I know is I love it and the car is more responsive.

[digitaloutsider]

How in God's name does that huge open-element make it any more RESPONSIVE? When I had that on my GP, I had to literally mat the pedal before I felt it start doing anything at all. It's taking away torque, not adding it. I think your ass-dyno is way out of calibration.

[Mach 5]

That ass-dyno your talking about is my foot in your ass if you don't stop complaining about my filter. Before my car started having injector issues I did feel it get more responsive. Maybe its because of my mind or what not, but all I know is that Im happy with it. That should be all that matters. And by the way, that WAI is now cold because the fan can't blow warm air on it. I also went out of my way to buy a plastic tubing instead of metal so it resists heat better.

wait wait wait......what GP do you have?

 

and you're better off just doing a K&N drop in filter...it seems to work fine for me

[Z34-5speed]

I know on my old 1993 Lumina Z34 auto, i ran it at the track the same night with and without the cone intake. The cone intake was consistently 2 tenths faster than the stock intake, with a k & n. Now on my current car i really want a true fender well intake because there seems to be alot more under hood heat which makes the car run like shit. Maybe some1 will actually get a video of a 3.1 or LQ1 on a dyno comparing intakes.

I dont have a vid at the moment, but my 3100 was consistantly 2 seconds slower to 60 with the cone. 2 SECONDS. I dont advocate driving with headphones on, but try it once. One run stock, and one run with the cone. That way you can stop using the EAR DYNO, and actually feel how much slower the cone makes it.

 

The 3.4 is not effected, because it is a completely different engine. DOHC motors love cones...
