New Magnuson TVS1320 Available for 3rd Gens

Looks interesting:

TVS1320 Toyota 3.4L V6 Supercharger System – Magnuson Superchargers

Kinda surprised they're still developing parts for these old rigs, but glad they are. I'm gonna have to look in to this.

Tempting!

I'm not sure if I'm glad or disappointed that it doesn't have an intercooler like the later gen TVS-based offerings.

Upside: MUCH cheaper
Downside: Less tuning capabilities.

Either way, glad it exists! They only delivered it a few months after they said they would, which is good.

That's odd that the graph they show doesn't match the 260/260 numbers they are spitting out. Also those peak numbers come at much higher revs. Granted I don't know much about boosting things but that seems a bit oversold. That said it does have quite a bit better torque throughout the rev range which is pretty cool. Not ever going to shell out 4k though so w/e.

It's a much larger rotor group with the TVS design (better than M62) so more efficient. Looks like boost is lowered from 7psi on old unit to 4psi on new unit and bearings are upgraded too and same power output at lower boost (cooler). A bit smaller pulley and 9psi on this thing would be making some good power I think. Pulley changes much easier as well. I could probably swap blowers in 30 minutes hmmmmm. Wonder what I can sell my current one for?

Mmmmm....nice. Even though it costs more than I paid for my rig, it does look nice for that big a performance boost if it really does what they claim.. What are people's thoughts about supercharging a motor with a quarter million miles on it, though? Seems sketchy but I have zero experience or science to back that up.

can you elaborate on how it has less tuning capabilities? maybe I missed it, but does this unit allow for a 7th injector to be installed like the original?.. the pictures don't let you see the other side....

Same here. 242k and I'm about to pull the intake to swap the knock sensors and valve cover gaskets. It would be nice and easy to just bolt that back on. I'm weighing a trade to a GX470, but I really don't want the bigger size and the loss of the roll down back window. If I could get the same power without sending my head gaskets flying, then I'd be tempted to keep it. Dropping the boost to 4lb, as I understand it, would help with durability.

This is something I am eagerly awaiting to see how the reviews come back.

Not a lot of info out there at the moment.

I keep thinking there's a way to make this work on pump fuel. How cool would that be dropped the compression just a smidge. Leave the fuel system alone. Man, how cool would that be?

Just the fact that they're using so much less boost alone will make a huge difference in Intake temperatures.

It would've been nice if they could've intercooled it though.

Lower boost would be better on the engine internals and provide more longevity compared to the old style SC in theory, yes? I'd like to know if it's quieter than the old style.

I mean it has lower max power potential than if they were able to integrate an intercooler. With the TVS blower though, it has higher efficiency, both at the stock boost and higher boost/pressure ratios.... (say, high 60's to low 70's vs. high 50's to low 60's) But the ideal gas law still applies - even a perfect compressor heats up air when you compress it.

Look at the TVS1320 kits for the later gen 4Runners and Tacomas though - all are intercooled.

Magnussen does make a BUNCH of different pulley sizes too... hmmm. Time to talk to the wife. :ballchain:

John's Tacoma (the single cab 1st gen seen on The Fast Lane Truck on YouTube) has this new supercharger installed already and his truck has over 750,000 miles. There's no doubt a supercharger can be harder on your engine, but I wouldn't hesitate to install one on a higher mileage engine given the opportunity.

Edit: John has a build thread on TW and goes deep into the tech and features on this new supercharger, read all about it here: 1997 Tacoma SX v6 5sp TRD supercharged 300 HP! Haltech ECU, Reg Cab 725,000 Build

"Boost" is really a measure of restriction so I'd not get to wrapped around the axle on that. I tuned my Hellcat and it doesn't even reference "boost" in the tune, it references aircharge that is measured in milligrams. So think of it more in terms of airflow than actual boost pressure.

More air = more power. Less "boost" will mean less heat which is a good thing especially on this non-intercooled style positive displacement supercharger.

I'd for sure wanna go with a bit smaller pulley if I get one of these. I'd wanna make a bit more power than my current setup which is a black TRD supercharger with 2.1" pulley and water/meth injection to keep things cool. I'd keep the water/meth on the new setup. That has worked well for me, and I have a URD 7th injector that gives just a spritz of extra fuel way up in the RPM/boost range as some extra insurance on fuel delivery and also enrichens fueling at part throttle boost areas.

Subscribed to his thread. Hopefully, he will get it on a dyno to verify their claims and report any issues on a high mileage engine

I just saw this announced too. I'm at a point where a SC might make sense for the build.

I saw in a FB group someone mentioned there isn't a need for the 7th injector kit with this TVS unit, due to "greater efficiency". I assume that is with stock pulley and boost though.

I'd like to see some folks running this on stock fueling and ECU for a while, and get their reports, before I drop the $4k.

I also imagine, and am hopeful, this means the used SC market will be more reasonable/affordable for us in the near future.

I imagine the high gear low rpm ping will still be a problem. I'd not plan to run this on stock setup without a piggyback to take some timing out at lower RPM and boost at a minimum.

He's been supercharged the entire time though. That's a major difference over being n/a for 300k+ miles then deciding to throw boost at it
I remember some user on here put on a s/c at around 300k, and despite his compression checking out great beforehand, it only lasted 10k miles before the motor cracked a head/blew a head gasket and killed itself

It's a gamble flat-out, no other way to put it. It's a risky maneuver that might pay out well, or it might screw you severely, and there's no way to find out unless you do it. Doing a compression test will at least give you an idea on the life of your piston rings and valve sealing, and whether or not you even have a fighting chance, but things like the integrity of your head gaskets and transmission are all still up in the air and just as crucial
It's a good sign it runs less boost than before and will reduce all this strain slightly, but is it low enough to be negligible for your car? Who knows, that's part of the gamble. People like to say "it's not permanent, you can take it off if you have problems" but that only goes so far and really doesn't help you with any serious damage that can happen
If it's not your only vehicle and you can afford an engine/trans swap worst-case-scenario, I'd say do it anyways. Otherwise I'd really think twice. I'm at 317k and have been wanting to add a s/c for a while now but this is my only vehicle and it would really suck to blow it up, so I'm playing it safe and staying n/a. Which really sucks, but doesn't suck as bad as buying a new car. I've heard some people say they're much harder on the trans than the engine, and idk how much I believe that since the A340F is pretty damn stout, but it was still enough to spook me

if you plan to maximize use of the SC and make the A340F last long, I think there's a need to have the valve body modified by specialists such as IPT and the tranny specialist that Gadget of URD recommends, but I forgot the name.

Mines been supercharged with smaller pulleys for almost 20 years. Trans is bone stock.

I feel the same way for now. Unless I stumble across a backup 4Runner to swap my mods to if I blew something up, I'm not inclined to take the chance. It was a dream anyway - I need a transmission currently. Like others said, I'm glad the new option is out there. I won't have just one of these rigs in my life forever.....I hope. There are quite a few still out there in my neck of the woods, and by that I mean urban, stock, lifelong garaged examples that are second or even 3rd vehicles that their kids didn't want......
