most miles without issue on superchargers

What's the most miles anyone has had a supercharger installed without major issues? Trying to get a ballpark on reliability, as it seems to vaguely somewhere between "the 4.0L is indestructible" and "Well, Toyota abandoned support and sold it to Magnusson's ex-Toyota owner because they didn't trust it over the long haul."

Thanks!

Only had my URD on for 10k. No issues with the SC or install.
All issues I've been dealing with have been exhaust related due to the headers, y-pipe, and cat-back.

Has anyone ever see one make it over 100k miles?

Not that it's remotely comparable but I have over 125K miles on my CTS-V. Most of those miles are modded with 14+psi boost and E-85 fuel. I do oil samples every 7500 miles and the engine show little to no wear. Toyota's engine build quality is better the GMs so that's something to be said. LOL

Over my years working at Toyota I've installed probably 20+ TRD supercharger kit and not a single issue while I was there. Unless you are in the boost all day long and keep up with maintenance you shouldn't have any issues. More damage can and will occur from owner ignorance and abuse than just normal supercharger use. That being said you are taking more risks though.
 
Installed one on my 2010 Tacoma at like 80K miles. Almost hit 140K before it was totaled. Never had issues except inconsistent performance. I blame the Toyota tune for that.

The tune can't change. More likely it was a poor tune to begin with along with heat soak and pulling timing. If it was strong at times but not others it can't all be blamed on tuning alone. We had issues at Toyota with the bypass valve not being adjusted correctly and bleeding off boost at times.

I always saw 6psi stock and 8psi after the pulley. Sometimes it would be a monster and other times it a dog. It was actually slower at the track the first time around after the blower went one. I never monitored AFR but I'd get puffs of black smoke on the 1 to 2 shift (auto) and when I let off at high RPM. It was just never right on my truck. The tune was verified to be the correct calibration file for my truck.

Sounds like it was running really rich and/or pulling a lot of timing out. So hard to get a "one tune fits all" calibration, especially on boosted vehicles. I've tweaked the tune so many times on my Caddy. It actually performs better on a "street" tune with a wideband then it did with the dyno tune. Boosted cars are very fickle.
 
I think a couple tuners are working on the sc 4runner - and finished a tune for the Tacoma version.

Hmm sounds interesting but not fully baked, though.
 
I had 200k on a factory TRD supercharger on my 2001 4Runner. I never even serviced it. It was the 2nd generation model for the 3.4L. I think it was made by Eaton. I also had the TRD 7th injector kit. It was totally worth it increasing the factory crank hp from 183 to ~270. It was a must for the 3rd gen if you towed or wanted to climb grades. I also ran 285-75-16 tires for about 160k of those miles. Of course, the cost back in 2001 was only $2k for the supercharger and about a year later $1k for the 7th injector kit that improved performance, hestitation and fuel flow. As for my 5th gen, I’m satisfied with the torque and the power seems adequate with my 275’s. I’m not sure at this time I would spend $5500 for one when the stated increase at the crank with the canned tune is only 30% over stock. If it were a 50% increase over stock like my 3rd gen I would be a little more interested. My TRD supercharger was installed by Toyota and had a factory 3 year 36k warranty covered by Toyota. Really like my 5th gen, but still miss my 3rd gen.

The URD/Whipple kit is $1k more at $6500, comes with 7th injector setup, and hits that 50% more mark.
