Thread: help a newbie beat the ricer squad

Sabrewings, have you scanned your IAT's with the sensor in that location?

I did scan and found that there is little to no air flow in that part of the box. This lack of flow creates a hot region. I let Jim at easyperformance know about my findings and he sent me an extension. With the extension I could put the sensor about mid way down the filter element so it could more accurately read the incoming air.

on topic to the OP. When I had my 05 Impala 3.8 na, I did a CAI, and 3" DP. It definitely killed my lowend torque and my MPG instantly dropped. I was getting 28 MPG on the hiway before the DP and immediately after it dropped to 21 MPH. The combination of loss of tq and mpg was quite frustrating. I'm sure that kind of mpg result is rare but none the less happened to me. The loss of lowend tq however is NOT that uncommon.

Not scanned yet as my Aeroforce gauge is in the mail. I take it you ran the extension to the filter neck and made a hole there?

And, I should note, I have a 2.5" DP and didn't notice any losses at all, but in fact gains throughout the power band.

I just fed it through the Wizaired PM strap and have it on the outside of the edge of the filter. Your idea of putting it in the filter neck is a good one, however, I have my stuff out so often testing things, it may be came a pain. I like it though. If the tubing were stout enough right before the TB opening would be ideal, but is not the case, unfortunately. If I had a shorter filter I would have installed it in the end of the filter, like some K&N's come stock.

Having a scanner ahead of time, allowed me to not only feel the difference from adding a DP, but allowed me to see the differences based on throttle postion. If you push the pedal farther you can overcome the tq loss. However I'm talking same throttle versus same throttle. I'm also that oddball that rarely has the radio on because it prevents me from listening for changes. OCD, probably.

Perhaps since you went with a 2.5" DP instead of a 3" may have made all of the difference. One thing to note, that tq loss was not only felt on my 05 LS but on the SS as well. Fortunately for me the SS didn't experience the MPG loss that the LS did.

When I put in my DP, the best part was the low end at first. Sure, some high end was there, but in parking lots it felt like I could barely touch it and she'd want to lurch forward. Took a little getting used to.

I already sent my stocker back for the $50, so there's no going back to scan.
