I'm procharged and looking to buy oil pump gear and crank sprocket

Hey stang. Any of them will be good over a factory one. Things ive gathered is that boundary gears are made of a slighty weaker steel vs MMR and TSS. I dont believe anyone has broken a billet OPG no matter the brand at our power levels. If/when I go with one ill be getting a boundary set with CS.

Do you have any links or info on the boundary gears being weaker?
No way to post something like that without some info or thought out reasoning.
I like TSS, cause they are based out of Orange, Texas, and have a long history supporting Ford. But I would NOT poo poo Boundary unless there was stout evidence for them being weaker.

That info is so far in the weeds... lol, I heard Tim Eichorn would rather that post disappear. I would take that thread with a serious grain of salt and its ripe for responsible moderator cleanup. You check YB and other forums first for any corroboration?

First off, our motors are interference motors. If you catch a valve you shatter the roller followers and the roller bearings love to ride the galleys down to the pump pickup. Run one thru an oil pump and the gears look like shit.

Then a story about a customer “bringing in” a torn up gear? Come on mang:shrug:

Either 9310 or 4140 are excellent choices and their finished properties can over lap considerably depending on heat treatment. These parts are built by laser scanning an OEM gear, processing the data to create a wire edm tool, and speccing a heat treatment by a production shop. Its pretty hard to screw that up. If you do screw up the material or heat treat, it will be hella obvious and someone will post a brinell series and bust the mfg on alloy or heat treatment.
If dims are off, people are going to post micrometer or at least caliper measurements (calipers are inadequate for precision gears).

Out of respect for people that bust their asses to build a business, I am simply suggesting that it sounds hard to believe Boundary has built a business around making quality gears for a decade and decided to make crap gears for Mustangs. Dont take my word though; there are trusted vendors (reputation and trust is their life) who feel compelled to make their first hand experience known.

Dont think so highly of yourself, I dont trigger easily, youre way overthinking my "feel free to search" response. You also missed the part of my response where I said if I get OPGs Ill get boundary so I dont know why you think im trying to knock them, just giving OP info to help him make his decision. Its a holiday, chill son.
