I guess there are a few different philosophies.
I would prefer low-end torque in a truck. The throttle response driving in town won't be an issue if you have proper throttle deadening. (Don't install a sprint booster).
A supercharger is probably easier to mount than a turbo in our application, but if you don't have the lower-end power a typical supercharger gives you you're missing the biggest performance benefit that it has over a turbo.

It is not recommended to install an SB. This kit is relatively easy for the mechanically inclined. The instructions are extremely thorough and those who have never installed one will be able to do it if they take their time. You are getting a significant increase and response in tq compared to stock. However, it isnt tuned to just be snappy to the point where you could break something. You have an increase however it is gradual. I dont know of any tuner where power/tq gained isnt adjusted gradually. You want a smooth curve throughout the powerband and the timing needs to make sense.

Stating the obvious but if you have a 4th gen different rear diff. 8" vs 8.2. Not really a size difference in reality, but it is stronger. Seen the 4th gen one break quite often. Still have not seen a 5th one break yet. Not saying it won't... just seems to be quite a bit better. The housing and shafts probably have worse limits than the diff. You break stuff with a heavy foot and big tires.... Shock loads will bust up just about anything other than a Dana 60 or other custom axle with all chromoly...
Front end is a different story and should be the same.. Still CVs typically let go before the diff.
There will be some boost down low, just not without throttle... we can speculate all day... but driving it will truly be the only way to tell for sure what it feels like.
The supercharger will not cause you to break in the rocks.. Your right foot might.

Actually, we're just trying to keep this thread on-track and focused on the OP's topic, without the sarcasm or drama...so lets keep that going. Feel free to add anything USEFUL to the thread. :director:

My concern with the axle is going up a pass with a trailer, I step on the throttle and get a hard down shift. For me that's pretty normal use. In generally I think the 8.2 has proven to be pretty reliable and durable. I'm not sure if anyone has broken one yet. If they have I haven't seen much info about it. Front Range builds a direct bolt in Toyota 9.5 housing that retains all the parts except the differential and housing - so it's fixable without a huge price tag. Or a limited with AWD is Toyota's default solution. But I am curious how hard Magnuson has pushed it's test mule.

We are mostly if not 100% agreeing with each other.
I will add; 100hp 4 cylinder trucks can break shafts and differentials just as easily due to their stupid high crawl ratios in their differentials. It has to do with torque.
So either way you are going to break stuff in the rocks.
Driving slower is a bit more controlled but sometimes you need momentum.I think if Toyota uses the same crush washer in the 8.2 its only a matter of time until they weaken... Although it does seem they are a bit more durable, if the FJ crowd is any indication.

It was tested pretty thoroughly on its way to FJ, to AZ, and many times on the dyno. They know what they are doing when it comes to testing. If they didnt, they wouldn't be as successful as they are. I can tell you I personally have had some fun with it.

So no updates on who was picked yet? I'm excited to buy one when they're done working the kinks out.

The individuals have been selected and will be getting notified shortly if they haven't already been. Some may or may not be on the forums.

I've seen 5th gen blow a rear-end, the same way the 2nd gen Tundra, 1st gen Tundra, and 2 Tacomas did this year. They spooled up on ice and when they finally hit pavement it shattered the rear-end (One Tacoma shoved a 1/4 of the ring gear into the housing hard enough that the tip of it was poking out). That's not including 1 Tundra front diff and 2 transfer cases.
Bottom line, not driving the vehicle properly will grenade your diff more than adding a supercharger will. Also keep in mind that the 4th gens used the same rear-end for both the V6 & V8 (gearing was different) and they didn't explode regularly with how often people use their V8's for towing and abuse.

Geesuz, understandable you could damage to failure in that that scenario but sending a shard through the casing, that is pretty crazy.

I wish I snagged a picture, was the most impressive rear-end failure I've seen in a while. It wasn't a shard, it broke a 1/4 of the ring gear off and shoved it into the housing so hard it started poking out the other end.

Magnuson has proprietary tuning capability for the Toyota ECUs where they can modify the stock calibration.
They will ship the kit with a canned tune for your ECU.
There are a few tuning shops that claim to have recently achieved a similar ability. One that I know of for sure is DAP in Dallas, TX. But they can only do it on the dyno at the moment. I will probably take my truck to him at some point for a custom tune since I may do a few other things to it....
Another option is the URD piggyback. That should be available very soon.
