this is off the intake I just popped out of my tx19 project, looks kinda hokey to me and it's a cast material. The cast part almost makes me think it was some kind of production or standard aftermarket part that was available off the shelf. I'm also curious about the five bolts across the back and the position of the other four bolts. The shoes I have in my other boat have bolt holes much closer to the front tips of the shoe which seems like a better mounting method.

Is the this type of shoe here garbage or can you buy solid new replacements that would work at triple digit speeds? Otherwise I have a stock berk intake I can have machined for mpd or someone's shoes and run that. Or I'm considering low pro

Thanks for the info Joe! This shoe is just so beat up and had so much pososity in the material, plus I would like to have the option of trying other shoes on for tuning. Does it look like something interchangeable with a shoe someone still makes or a custom one off? Since the bolt pattern is so differant than what I'm used to I was thinking of swapping intakes to use someone's shelf shoes on this. I also plan on setting the intake at 5 degrees versus the 2.5 it was at so id imagine I need to start from scratch with the shoe?

That custom shoe I had machined out or a chunk of aluminum I got from k and h metals ran over 300.00 said and done.

Dollars?!?!?!

13.5 is the standard intake opening size.  A half inch change in opening size ROUGHLY corresponds to 1/16" change in biting edge depth.
