That would be the one. I've been running it, but only because it was under $100, not because I need it. I doubt he'll do a comparison of it in the vids.

If you watch the f-150 video, at 30mph it too was starting to get bubbles if you watch the bottom. The Ford never went to the 50mph that the dodge did either which really showed the bubbles.

Iíd be willing to bet all this testing was actually done over a day or two and the rest of the time was spent editing and reshooting the videos so they worked for them. IMO the evidence is inconclusive.
Its too bad the "baseline" wasn't the 11.5 diff, so I'm sure the evidence is being persuaded a touch. But at this point, I'm siding with Banks

Why exactly? Just curious.

The way I see it there are thousands of trucks with aftermarket out there, and yet we donít really hear of an excessive amount of diff failures do we? Or do I just live in an area that seems immune to a possible issue he is trying to expose?

One of the things I don't understand, is that he's acting like the pinion gear and bearings only get lubed by what the ring gear slings around. Isn't the pinion low enough to get it's own lube? Especially when it's overfilled.

Exactly! Also, why didn't Gale show the Mag-Hytec filled to the high line (8 qts)? Probably because the rotating assembly flooded the pinion with gear oil...

How many people tow at the max gvw? And there's a safety margin built into everything. I'm with Banks on the aeration in the oil.

I am curious of the ppe which i bought has fins on the inside, i wonder what that does and i am curious about heat... that is pic of the tranny pan, but diff is close to the same...

Default Banks Diff Cover Video

Pinion bearings will only see oil from the ring gear, the way it rotates, the ring gear is constantly pulling the oil away from the pinion when submerged and then is slung up to the top via the ring gear. If you open up a diff, you will see the channel for oil to be slung into and feed the pinion and also see oil keepers.

I donít feel the cover is stopping any amount of fluid from hitting the pinion bearings BUT Iím very curious if it is causing the oil to heat up more than a stock cover due to the increased work happening to it. thatís what will get me to either get a new cover or keep this maghytech.

The airration doesnít look any different and with the cover low filled, I only see that helping keep heat down if anything

It says right on mag hytec site that they run cooler. No actual specs though.

Not quite, James post describes it well. Also you may want to think about when towing up hill when the pinion will be at a higher angle and may not be submerged. It is the port above the pinion barring that the ring slings oil into that provides the real lubrication

ok, now hes making sales pitches and no longer actually doing any factual testing.



He is claiming all these things about lack of oil flow, heating temps up more than stock, loss of hp, etc yet he STILL HAS NOT SHOWN A SINGLE DYNO RUN beyond the stock one he did like he stated he would be doing in the very first video to show the temp difference. Instead, hes jumped straight into making his own cover to "fix all these issues" and no data to show for it...

I had faith he would follow through but after the monster drink pose and now this video, its clear thats not the object of the videos... that has certainly irritated me.

I agree with you. Either way aftermarket covers are useless (unless you plan on backing into rocks or something).
