Slower after intake horn mod

[Rnolan]

I ran in the 12.5s a couple of weeks ago, after that i did the intake horn mod and ran consistant 12.7s. Do I need to make tuning adjustments with this mod?

good questions... i guarantee the Intake Horn Mod itself will not reduce horsepower. Did you removing any other components having to do with the boost tubes or y-bridge? You could have a boost leak. Post your before 1/4 mile slip and your after slip

The one on the left is my best before the intake, and the one on the right is what it ran with the modified elbow. Last nights conditions were much better then the night I ran the 12.543 on too.

It was on two seperate nights. I ran in the 12.5s for a few passes one week. the next week it went into consisten 12.7s then on weds i did 3 passes all around 12.6s. Racings pretty much done around here for now so I have a while to mess with it.
