Magnuson supercharger

Hi folks,

I've been sleuthing the threads for a long time, but never registered. Does anyone have any information re: Magnuson customer support? I'm planning to purchase a supercharger for my 2017 Tundra within the week, install myself and hopefully, many more trouble free miles of happy driving afterwards Is customer support good if issues arise?

And is there a warranty on the blower itself if problems come up?

Thanks,
Travis

 

Warranty info is here. https://www.magnusonsuperchargers.com/Articles.asp?ID=254 Read the fine print, as I am not sure if you get the warranty if you install yourself. I thought I read somewhere (could be wrong) that you had to have a Magnuson approved installer do it to have the warranty.

 

Thank you. I had saw the page, but didn't read through it carefully. Appears that they warranty it for 12 months / 12,000 miles if installed by an ASE certified technician (I will have one of those guys by my side the entire time). The truck has 62,xxx miles on it. I've read through the entire 76 page installation manual 5 times, about to be 6. LOL.

Can't wait for some boost, though. It seems the engine tolerates it pretty well, as long as you aren't abusive and keep up on maintenance (both of those items are a check check). I do a fair amount of towing (an 8K lb. 5th wheel camper). Hopefully the blower won't screw up the trans or any of the engine bearings. From what I can find, neither of those things are an issue, provided I do adequate maintenance and don't redneck it.

 

I see in your info that you are on a flex fuel? I thought there were issues with flex fuels and the superchargers? I've not seriously considered one, so my knowledge is pretty sparse, but I thought I heard that somewhere. Any truth to it?

 

I spoke to Magnuson on the phone regarding the Flex Fuel situation, last year when researching their supercharger. They told me there were no issues with their revised supercharger on Tundra Flex Fuel engines. If memory serves, they stated that they have updated the injectors and the Bully Dog tuner which is included in the package to make everything compatible. They also stated, for reasons that I cannot recall, that the updated Flex Fuel compatible supercharger setup actually puts out more HP than the original Tundra TRD supercharger.

 

Cool beans. Good info for the FFV crowd. Thank you.

 

I would also look into the harrop TV2650 supercharger

 

Good luck and report back. That is going to be an awesome upgrade. If I thought I could get away with it I would order one right now.

 

Whipple has one out too.

Yeah - I saw the Harrop and the whipple. I'm probably gonna stick with the Magnuson blower because it's been tried and tested and I honestly can't find anything negative about the kit. The Harrop has the benefit of having larger displacement (2650cc versus 1900). The boost provided by the Harrop is the same as the Magnuson kit (6-7psi), but the Harrop offers lower discharge port temps. I don't know how much of a difference this will make, but in my mind, not a whole lot unless you're wanting to increase boost and custom tune it. And yes, one added benefit to this one being a FFV is that I don't have to replace the fuel pump - it's already a high flow pump. I believe the non-FFV trucks require the additional step of dropping the tank to replace the fuel pump (the included pump being the one for the FFV). I'll post back with updates, but hoping for weekend after next.

And yes - the Magnuson kit is advertised as 550hp, which is 50 more than the TRD kit provided. I believe that hp figure applies to both FFV and non-FFV, probably as a result of some clever tuning I'd imagine.

 

Hum very interesting I’m really excited to hear how this goes keep us updated I am wanting To do this also it’s 7000.00 for the kit right

 

Magnuson manufactured the S/C for TRD. From what understand its the same S/C wthout the TRD stamping. I've seen different tuners used with the Magnuson so this may vary per kit. Performance will generally be the same between tuners.

 

I did the install myself a few years back and did a little thread https://www.tundras.com/threads/diy-supercharger-install-2016-5-7-ffv.26402/
Very easy to install and a little time consuming, I have to check back with Magnuson about injectors and see if tune has changed.

 

RE: Warranty

From the PDF posted on the Magnuson site AzureNightmare linked:
Term: 36 Months / 36,000 Miles Time Measured from Vehicle Original In-Service Date. Mileage Measured from ZERO (0).

Sounds like no warranty at the expiration of the terms above; this is consistent with Tundradude34's review of the Magnuson S/C on YT. If you have any doubts I would get clarification from Magnuson, I've had good luck getting a quick response from them via eMail quickly.

 

Welp...the commencement ceremony begins tomorrow at 0830 MDT.

 

You'll love it. Added mine in February 2020. I'm also flex fuel and 56k miles on the odometer when it was installed. I got the new injectors with my kit and hptuners for the programmer.

 

Thanks. Can't wait. Same here. New injectors and HP Tuner for the new ECU calibration.

I'm at 63,xxx miles now. I'm also in AZ, in Kayenta (on the Rez) about 2 hours NE of Flagstaff. Elevation here is around 6000ft. Driving without a load isn't fun and with a trailer just plain sucks. I can tell the transmission shift points change as elevation climbs, guessing as a result of the lowered barometric pressure sensor readings. Holds gears SOOO long and downshifts unnecessarily IMO. Have you had any experience with driving at high elevation? And any thoughts on that?

 

Omg a dream is coming ture today hell yea

 

Honestly I haven't driven at elevation since the install. I did take a trip to Palm Springs, CA last month which was the longest trip I've been on since the install. Power on the freeway was a major improvement, plenty of passing power with room to spare.

 

Welp. It's done. I'll post a photo later, but honestly, if you've seen one, you've seen them all. There is an unresolved issue. The very first section of the installation manual - flash the HP Tuners calibration to the ECU went fine. Then the instructions report to open VCM Suite and watch the ethanol sensor % after starting the truck the first time and watch the alcohol level "decrement" over possibly 10 minutes until it reaches 0%. Mine never did that. First drive, it settled in at around 30%, second drive, it settled in at 14.9%. Tried their procedure of refueling and then unplugging battery for 10 minutes and then it settled in at 27.2%.

Magnuson tech support was phenomenal via email - basically, they said it must be refueled with at least 8 gallons to trigger the ethanol sensor reset (??). Basically, none of this makes any sense to me at all. They said that spirited driving was okay because high ethanol would cause a richer mixture, which was safe, but in their instructions, it's supposed to read 0%. I've watched catalyst temps via Torque and they haven't gone over 1300 deg. F. AFR sensors won't report anything lower than 11.96:1 (I'd imagine some programming trick with the calibration supplied by Magnuson). But at least I know it isn't running lean at all. Any advice on the above is appreciated. I'm continuing to work with Magnuson on this and will report back with an update on this. I just don't understand what's going on here, or what's SUPPOSED to be going on...

Onto the good stuff:

1) the power increase is pretty insane. I recorded a rough 0-60 time of 6.5 seconds and I'm at 6000 ft elevation. It is gratifying to say the least.
2) my biggest gripe with this truck was how badly it hated to stay in 6th gear and ESPECIALLY at elevations like this. The transmission was constantly downshifting to 5th and sometimes even 4th when climbing very small grades. Not anymore. It holds 6th gear with torque converter locked like a champ!
3) the sound! You've heard videos. Mine's no different. It's a little bit orgasmic.
4) highway passing power is where it shines. There's no need to ring the gears out to near redline. A downshift to 5th or at most 4th gear to get moving quickly is all you need.

Stay tuned for more info re: EtOH sensor or if anyone has any advice, please chime in.

Thanks,
Travis

 

Good read. Can't wait to install mine, looking for all the same reasons as you

 

Update on this ethanol sensor issue. Magnuson tech support has been AMAZING!! I've exchanged numerous emails with them and they have gotten back to me immediately each and every time. I've been very impressed!

So this is probably common knowledge, but not something I've ever cared to research or find out, but now I do care and after some pretty exhaustive reading on the forums, etc., have discovered that apparently, our Tundras do not have an actual ethanol density sensor. Toyota screwed the pooch - they utilize this whacky algorithm whereby the ECU uses long-term adaptive values in combination with watching AFR's for the first 5 minutes after refueling to determine the ethanol % (and locks that number in for the remainder of the tank I guess??). I've also read 10 minutes and also 7 miles - take your pick, but within a short time/distance after refueling with at least (again, conflicting information) 3 or 5 gallons (but Magnuson says 8 gallons - that's the one I'm trusting), the ECU calculates the ethanol density. I've never cared to look at the ethanol density before now, so I have no idea what was running pre-supercharger, but would about guarantee it was running higher than 10% (have never ran E85 mind you). Anyhow, as explained by Magnuson, for some reason Toyota is being selective about which trucks get an ECU and fuel pump update to remedy this issue. An elevation in the ethanol % causes the AFR to run richer, which according to them, as long as it isn't reading over 30% should be fine. It's pretty well documented on the forums that some of the 2015 and prior models had the cold start issue when the ECU went haywire and started ramping up the calculation causing an excessive rich cold start and open loop operation causing startability and cold idle problems. Apparently part of the supplied tune is aimed to alter the ethanol calculation logic in an attempt to get it to read lower, but there is no way to just turn it off like with GM and Ford. 0% is optimal, but not a huge deal if it doesn't read 0. As said, they advised that 30% and under was okay.

I'm going to send a logfile using VCM Suite to them next time I refuel and let them look it over to make sure it looks okay. And to be clear, the truck runs GREAT! There are no issues other than not liking the numbers I'm seeing, which apparently is okay too.

Will post back with an update later next week.
