finally fiished cleaning up the lower of the Track Heat. it's going on the combo in my sig. the numbers i made were with the cobra intake. what are your guesses as to what the new numbers would be. also, the a/f was a little fat at 11.5:1. we're gonna lean it out to maybe 12 or 12.5:1. and the n2o is currently not installed. thanks.







here's the upper and TFS elbow which i painted the letters on:

Isn't the TF lower the highest flowing lower out of the box anyway?

So was there still allot to remove?

1 more thing, are u sure thats a Track heat? I see the emmission port in the middle, I thought only the street heat had that?? It looks like my Street Heat.

I just go done with my lower as well(TFS-R). All I did was smooth out all the casting burrs and finish with a 400 grit roll. Smooth as a babies butt now. I would show a picture but I cant get the pics file size small enough to post.
