Are you running it down track or just in the pits? On my sons 500 hp LS1 street car we lost 6 hp on the wheel dyno with the air filter on. Tom

The reason for the loss is attributed to the permeability of the gauze media in question - approximately 80 SCFM per square foot at .5" w.g. In addition, the outlet configuration and resulting profile are poor.

Why are you considering the use of a filter?

I run it all the time with filter.

I'm guessing you don't use the Jessel belt driven front mounted distributor? I used one at dusty tracks, until I went to a Bowtie block and put that thing on. Won't fit now. I have zip tied a damp shop towel over the TB to try to keep dust out of my cylinders. At Noble I often pull it off in the staging lanes, put it back on down on the return road. Every year I swear I'm not going back. LOL

I don't have a Jessel belt drive as I don't think that would be allowed in Stock. I use a filter to keep non air particles or chunks out of engine.

Nobile is one of the dirtiest pit areas I've encountered. Ennis is right there too.
