PI Intake Swap & MIL

[Blev]

alright well heres an update.....


after driving to school approx 30 miles rountrip....there appears to be no whistle anymore.....when I pulled in the garage I got out to listen for a leak didn't hear anything so went to go turn the car off and WHAM....check engine comes on.....so I am going to head to autozone here in a few and have them pull my codes and see wtf is goin on......

all in all car still runs strong ...but I want to get this ***** figured out!

What did they say?

Lean in both banks........same as before just minus the gauge issue....so I am thinking maybe 02's or maybe it's just taking longer....I finally got a hold of my buddys obd2 reader and I erased the codes and am gonig to see if it fixes itself this time...or if the codes come up again...if they do then I will get a little more involved....but for now the car runs great and pulls like a MOFO...

I will keep you posted...

Does the PI intake really make that much of a difference on our 96-98 mustang's? I thought it was the heads on 96-98 that lacked the power? If it is the intake, how much hp do you think you gain and was it noticable?

Yes....

The PI intake alone is one of the best MOD's out right now for the price. A solid 15hp has been seen with almost everyone who has done this. There are also the PI adapter plates which is supposed to increase the hp/tq numbers by making the transition of air from the PI intake to the non PI heads smoother. I have them but won't be on the Dyno til Saturday, so I'll post numbers than. You will obviously benefit more from the entire headswap, but not everyone can afford to drop 1600 bucks (not including labor) at one time for the swap. The intake swap is very straight forward and is just a matter of taking things apart and putting them back together. As for SOTP, it's their in a big way once you hit about 3300 RPM's. You can do a search for it see what others have said about it. I don't think their is one person who hasn't been happy with this mod.

Yes it makes a huge difference....my car feels completely different....as blev said people have picked up 15-25rwhp peak....and at 6000rpms' where are cars make nothing people are picking up close to 40rwhp.......so for less than 200$ for everything it's a damn good mod for the money......unless you go with the adapter plates then it's more expensive...but you hvae piece of mind....which may be worth it..

i dont think you o2s are bad, it is just saying that your car is running lean. when my o2s went bad they said circuit malfunction. i think maybe that you just need to get your car tuned.

not sure why I would have to get my car tuned when people with the same or less mods than me do not........so I don't think that is the answer..IMO.

update....light came on....again...so something is definately causing this to happen..now I just need to figure it out...

First thing I am going to do is check for vacuum leaks, and leaks around the intake as best as I can......if I don't find any smoking gun then I will swap out the o2's for a buddy that has an extra pair laying around....and if that doesn't work then I will probably be forced to redo the swap

This may sound odd, but it works. To check for leaks, get a piece of PVC pipe(any pipe will do) about 2 feet long. Put one end to your ear and move the other end along the engine. This will help you listen to one small area rather than the entire engine. I'm almost sure you have a leak along the intake. Good luck!!

 

[ChadS98GT]

well today me and a buddy checked for leaks with carb cleaner...and he had a car stethascope.....we couldn't determine if there were any leaks.....so then we also switched out my o2's with a buddys to eliminate that problem........and still getting the lean in both banks problem....

The intake is coming off tommorow and I will be redoing it........can't think of anything else to do...

With the swap you could feel alot more low end torque too? If swaping the PI intake is a realistic 30 hp at the wheels then Im doing this next on my to do list. Is it as much of a feel as gears: going from 2.73 t0 3.73?

I have only seen Dyno numbers that show about 16 - 20 HP gain. However, the boasts of 30 - 35 are said to be from the adapter plates and I'll have my car on the dyno Sat. to see what gains truly come from the plates. In either case, the PI intake is a must do mod for us pre 99 guys that can't afford the entire headswap. You can always get a set of heads and build them up yourself and than slap them in when your ready!! Either way, I say do it

 

[mustang90]

Im going to use the livernois kit eventhough its 650 bucks. I think I will also throw a upper intake elbow on at that time too if the price is decent with a upper/lower spacer. The Pi heads only add 10 hp from what I heard. Please show the dyno #'s when you get them!

I have done this mod as well and it's better IMO.....I think it makes the gears actually feel the way they are supposed to.......our cars have such crappy power up top and with this intake swap it helps alot.....you will not gain much torque....mainly just HP.....but I notice it from about 3k all the way to 6k.....trust me it's worth it....even though I am having to go through all this B.S. to get it working...

I didn't feel anything below say 3,000rpm with the PI intake alone, so IMO, no low end torque was added. Now, the PI cams did add some torque felt down low for me as well as hp felt in the upper range.

Blev, Any update on the dyno?

You don't wanna know. The guy broke my throttle cable mod on the first pull, so I wasn't able to get WOT. I saw some crazy numbers before it broke than it dropped like a sack of potato's. I swear I saw 238 but they didn't print it out. They ran my car 4 times and all it would hit was 200. So the only thing I could think of was it was becuase the throtle wasn't all the way open. I don't know. Here I am up on the Dyno preparing for dissapointment.

 

[LI98GTStang]

Sorry to hear about your troubles. I wanted to see some decent numbers out of your car before the PI cams. Nice hood props though.

 

[ChadS98GT]

eeek how did they break your throttle cable???


I redid my swap and everything is good now....no ses codes or anything runs strong.....I will have numbers soon...hoping for a nice suprise

i know im comming in kinda late, but the PI intake bolds directly on? i thought the PI intake had to be port matched to the NPI heads. where can u buy these kits with the adapter plates and what not to do the complete intake swap? and how much does it run in $$$.
