3.4L supercharger

Light boost in closed loop is the only time it runs lean. As long as I'm in open loop my AFR's look great at any boost level mostly. The only odd thing I've noticed is that my AFR continues to drop the higher up the RPM range I get.

At about 3100' where I live and at about 5k rpm my AFR is right around 11.3-11.1. Took a trip the other week and about 5500' my boost was obviously lower but my AFR's were dropping to 10.7-10.5 around 4500 rpm.

Only time I've heard even the faintest bit of ping was when it was 80+ degrees. So far I'm quite happy with how everything has been turning out

 

So envious. I have one of those mega pingy 5vz's that I'd be convinced has some kind of damage or buildup causing it but I've read Gadget writing about coming across 5vz's like this that have no known issues. I think he even theorized some kind of tolerances in OEM parts that allowed odd-ball combos of parts that maybe have slightly higher compression or something. Maybe more likely is a variance in TRD blowers making some very inefficient and the charge air much hotter.

I've had to add so much fuel (closed loop splitsecond enricher + EMU) and pull so much timing I don't think a standalone would give me any gains anyhow.

I need to get my EMU fuel map switch fixed so I can start rocking E85 again.

 

Its almost like you should undue the FMU mod and put the OEM FPR back to atmospheric.

 

Everyone that just bought a brand new MP62 supercharger is probably saying wtf right now

That's awesome they are still developing new stuff for this engine. The built in intercooler system is a big upgrade over ours.

 

I guess I’ll be upgrading in 2023.

 

Wait what? Intercooler? Got a link to info?

 

Gabe Salazar
Just talked to Gabe who is at the Sema show in California and was talking to Magnuson.

The supercharger will NOT have an inner cooler.
The rotors will be a newer more efficient design,
Rotors will be 30 percent larger turning slower making less heat.
BUT cfm will be the same.
I guess a small pulley will create more air flow at the end of the day tho than the old supercharger,
Supercharger is still in development,
They may try to get the output to a higher number then the old supercharger with the stock pulley.
End of summer ETA,
Again it’s still being developed,
They need to get it to the 300hp line in my opinion

 

Booooo! I WOULD have pulled the trigger if it did, but not now... darn.

"no calibration needed"

Doubt. I doubt the efficiency gain is enough to make us pingy types no longer ping. And for the non-pingers you will still be loosing out on power, just look at the piggyback gains and then the even bigger gains of Haltech peeps.

IMO short of EMS the only thing they could do on their end to really nip low gear/low RPM high boost ping is to make the mechanical calibration or electrically control the bypass valve to simply not allow as much boost in lower RPMs.

 

I could definitely see that as with cooler temps, it should greatly reduce the tendency for knock. Now, whats needed to run it and whats optimal to run it are two very different things. I can see that being a good marketing point for the usual buyer that isn't in the know. Pretty cool to see a small comeback for these trucks lately

 

It'll need an intercooler for me to do a swap with my 2nd gen supercharger.

 

Weird that the info card in the photo says it's intercooled, when it's not? Unless I'm reading it wrong.

"High efficiency intercooler system for maximum charge air cooling and sustainable performance"

unless they just pulled that bit off the description for the same blower for the 2nd gen Tacomas, which does have an intercooler.

 

I think that’s the same model number as the 4.0 supercharger. Couldn’t actually find this one on their website.

I just received mine in thw mail. It’s still in the box!

 

From GABE SALAZAR at the SEAM show,

“The reason for the upgrade is tooling, it’s not really an upgrade it’s a replacement for there existing tooling‘s they’ve been using since the 90s that is worn out so they had to make a decision between rebuilding their own tooling, continuing to use the existing rotors or creating a new design with more efficient rotors and by doing a new efficient rotors to help reduce the amount of air temperature.”

“The misconception of the wording so while at the Sema 2022 decide to get the answers the truth is they are going to a new rotor design that will make the new supercharger more efficient which will reduce heat but it will not make any more additional power.
the new changes are due to tooling changes more than an upgraded supercharger and what you see is a 3-D print of the new supercharger,”
ETA is late summer,

The new supercharger will be more efficient spinning slower with 30 percent larger rotors with more air flow making less heat but the same hp because of emissions standards, (CARB certification) supercharger has to be the same specific, if they change that the new supercharger would have to be installed on each year truck to see if it passes.
So theoretically you will be able to get more power available over the old design if a smaller pulley is used because the new supercharger rotors will be pushing more air then the old rotor design if compared at the same rpms.
Because this supercharger is in the design stage it’s not known what the CFM is compared to the older supercharger at the same rpm’s.

If the new rotors pushed 30 percent more air theoretically there would be a nice potential for more power at the same rpm’s with a smaller pulley over the old supercharger.
Their is NO intercooler in this supercharger!
Price is not set but will be maybe a little higher

 

I politely disagree. With just water spray on my old meth kit it wouldn't stop audible ping.

Key word, audible. That means there is inaudible ping happing just below that threshold.

More context to my opinion is use-case too. I want Toyota reliability, meaning going up a mountain pass in constant low rpm partial boost EGTs are not getting out of hand. Or other long duration high stress driving. I don't like 'no calibration needed' if the consumer reads into that "nearly as reliable as before" vs "you might have to change your driving at certain loads and keep your ears open for ping".

Thankfully these 5vz's are stupid strong. In no other platform have I ever heard of so many engines pinging under boost and not granading shortly after.

It's partially the reason I made an electric S/C bypass mod. There are conditions when I'd rather not be boosting -
https://www.tacomaworld.com/threads/sc-bypass-switch.582614/

* The bypass is small, it doesn't fully bypass all the SC air at higher RPMs so you still get some boost going up grades. Wish there was an easy way to upgrade the bypass.

 

Tell you what, I like the way the Gen2 supercharger looks (one piece, OEM looking) and the now Gen3 (I think its safe to call it this), but hot dang the Gen1 variant is better for the tinkier types:
1) modular design allowed one person to DIY an air/water intercooler setup (googling now to find the thread)
2) said modular design also makes the bypass external and can be dissembled = easier to modify to increase it's capacity.
3) IMO it looks like the gen1 bypass is already higher flowing



If I twin charge I'll likely pull off the 9.5lb 2.2 pulley to an underdrive variant that pumps about 5psi. 9+ lbs of boost under 1.5K RPM is just a huge timing pulling, tire scorching ping-fest anyhow. The 5lb pulley will be much more forgiving to the bypass restriction. Or hell the 4psi (that option is new since last I checked)- both designed for the "no calibration needed" people that live in Ping hell/have adversely pingy 5vz's.

I could very well be wrong, thats just my opinion based on general theory and experience with forced induction platforms that the lower the IAT, the better chance you have to run higher timing and/or reduced knock.

I've ran mine with just water vs water/meth mix and theres a huge difference. With just water it may be cooling it a little bit, but not the same as methanol will. I have a 98 with the old TRD FMU so even on shitty california 91, its rare I get any pinging.

 

Well, it’s gonna be a race to get ‘em apparently. That’s awesome an intercooler and larger supercharger, aftermarket control mods mean we’ll be able to add some horseys when this comes out. I’m gonna be saving for the year so I can plop one on my single cab manual and then my 4 door will be sad

 

No intercooler, that was an error, it’s still in development, ETA end of summer next year

 

Yes, but some of us super pingy 5vz's this is just not enough. I'm jaded- when I went two step colder plugs I was hoping for improvement- nada. Went with 160 thermostat- nada. Its taken sometimes -9 or more degrees of timing retard AND very rich mixtures to get rid of low gear/RPM boosted ping. Some of you peeps are lucky and don't ping and doing fuel/timing mods just gains you power.

With mine, before getting EMS just getting into 1psi would cause audible ping. Did colder plugs, thermostat, FMU mod, would still ping at anything 1psi + unless I went WOT (air fuels would get rich, RPMs shoot up).

Yep, sounds like you have one of those boost friendly 5vz's that is easy to please. Anything you do probably makes your setup just that little bit safer. Its like some of the super pingy 5vz's have glow plugs or something lol and to mitigate the spark knock or pre-ignition it takes a lot of tuning (timing retard + enrichment).

I bought my rig 2nd hand so if I camera my pistons maybe I have pop-corn (pitting) on them and the googles says that makes an engine much more ping prone (hotspots). But I do recall a post by gadet (or on his site) mentioning he has run into a number of ping happy 5vz's, like there is some factory variance because everything he investigated (camera the pistons, valves, timing light, fuel enrichment, injector cleaning etc) was not the cause.

Another variable are the blowers themselves. But with mine I took it strait to magnuson for a service/rebuild. They replaced the screws, all bearings etc and it wasn't less pingy.

E85 was by far the funnest, got to zero out timing retard (when I was using the AEM FIC). I haven't run E85 on the Greddy EMU but I look forward to feeling what advanced timing in boost feels like (greddy EMU can do that). These standalone cats can take E85 to the max (perfect Air Fuels and massive timing).
