So are there any TRD Superchargers left? (2 Viewers)

Was hunting for a TRD 3.4 supercharger kit for my buddys 4runner (thanks for helping Beno), he wound up getting one from Toyota of Dallas aka TRD Parts 4U, and while talking asked what was up with the 80 series charger. The salesman (can't remember his name) claimed that TRD approached them with a new design 80 series supercharger kit and asked if the customer base would pay for a $7000 price point. The salesman claimed that TRD Parts 4U responded "no", and they believed the future of the 80 series supercharger is not likely. Absolute truth? Don't know, but it doesn't sound good
 
Don't forget the 80 is a world market not just the US.
 
And most are diesel.......:meh:
 
There are a ton of petrol trucks in Australia and south america

They should come out with a kit and immediately discontinue it. That will ensure alot of people will want it.

And Australia has the Sprintex kit. So I wouldn't hold my breath for a ton of TRD S/C demand Down Under.

I don't see the system on their price list anymore.
 
Hmmm that Sprintex SC is kind of weak. They list 316Nm at 4160 rpms. That is only 233ft/lbs. I made 453ft/lbs at 3300rpms. lol. So much for that old theory of SC's making more torque than turbos down low. :flipoff2:

With the current exchange rate the way it is, the cost is comparable to a TRD unit, not counting the tuning it says is required.

I personally don't like a few things about it:
1. It's ugly, clunky, however you want to put it, not aesthetically pleasing.
2. It requires a piggyback ECM and tuning.
3. It comes with additional boost injectors?

For all of that work, may as well go turbo like Scotty and put out some serious numbers. But that's just one man's opinion.

It does NOT require a piggyback ECU (and even if you went with the ECU, it comes with a basemap; tuning isn't required, and is only if you'd like to tune for your specific setup to harness max power output).

And the ECU + additional injectors are OPTIONAL.

Basically the Sprintex is the same as the TRD power-wise, but will only surpass it (50% more HP vs the TRD at 25% more HP) IF you utilize the OPTIONAL ECU & injectors.

But I really don't wanna hash out all that info again. You can read all about it here: https://forum.ih8mud.com/threads/sprintex-supercharger.451246/
 
Not sure if that was me scott or someone else, but for me I wouldn't do a bigger SC in stock form and I wouldn't add a smaller pulley unless I intercooled.

The reason, if you start pushing too much air too soon, you are making too much boost in closed loop. With really big SC's you can push a lot of boost right away because it is engine driven since you can not adjust the fueling it is not what you want. The opposite side is that with a small SC like the TRD SC you can't make anymore top end because it is basically linear based off of screw RPMS, which are based off of engine rpms.

If you had smarter boost control or ignition and fuel control you could make it work by basically opening the bypass in closed loop situations keeping boost in check and then closing it and adjusting as much boost as there is fuel to handle in open loop. How you could get the boost controller to recognize the open and closed loop conditions would be a tuning nightmare but it is basically a second option on how to setup a piggyback.

Or go with a turbo type setup that I have laid out in other threads that allows you to control boost by rpm and you should be fine.

nah. I'd like to see what Scott would spec out for a good SC.

I think running on the stock fueling is a big part of the lack luster performance numbers from the TRD unit as well as any power adder that utilizes the stock system.

At just above atmosphere it runs a 10:1 AFR and beyond that it pulls timing. Not good for performance numbers
 
Well the TRD system is really maxing once you start spinning it faster. The M90 was somewhat designed to go on the 3.8L Pontiac, Buicks and Olds with their L67 engine.

The third gen M90 at maximum rotor speed is rated to about 500cfm. You convert that to lbs/min and it is only ~34-35lbs/min, then subtract the 42hp to spin the SC at 12,000 rpms to make that volume and you will see less than 310 crank hp. or roughly 205hp at the wheels.
