Toyota Supercharger Removal

I would just give them a call or go in, they build and tune everything you can imagine.

I am sure Dan can get you set up pretty quickly.

I used to run with these guys and they are amazing at working with F.I. and tuning.
 
The TRD super chargers where never installed at the factory. they where a dealer installed option. (just FYI)

The "tan" model had a few issues and was updated to the "black" model. the black one works well and I have seen no ill effects. A coworker of mine has ran his for 120K miles (now has 210K) and no problems, even has the URD underdrive pully for the crank, and SC, he is pushing about 10psi and has no problems. he just installed the URD 7th injector kit. its amazing. I would run the 7th injector kit if you go past the stock pulley. if you don't then you should be A O K!

I would leave it. Toyota would not only honor the factory warranty with there kit, but include any Super charger related parts in there 5year 60K drivetrain warranty.
 
What psi do these run stock? When are they supposed to kick in? Is it supposed to be a noticeable boost like a turbo or is it more gradual? I've had several turbo vehicles but it's my first supercharged. How do you get it to run more psi safely and does it have to have fuel and air tuned to do that?
 
I am honestly not 100% up on "modifying" the setup. But it "should" be ok as is, and with the upgraded pulley.

To get more boost you put a smaller pulley on it to make the RPM of the supercharger higher in relation to the engine.

No its not like a turbo, the super charger has a fixed spool ratio to the engine so it does not "spool" it is constantly turning. the more load, and throttle you give it the more it allows the supercharger to compress, but its a instant thing.
 
130k on a stock TRD setup, zero fueling, pinging or boost issues... wouldn't own an auto 3.4 without one personally. I drive customer vehicles on a regular basis and built trucks feel absolutely anemic without the SC I'm used too... so much that I'm pretty much making it mandatory for my Tacoma#3 build. My 2 cents.
 
Does installing the urd pulley that increases boost cause any known issues?

Sounds like from everyones experience I'll be keeping my supercharger. Sorry Colton, Brandon, and the many others that were waiting in line. Colton, you'd just sell it with your runner in 2 months anyways so it'd be a waste.

The TRD supercharger isn't going to hurt anything or do any damage, they're engineered by Toyota.... they know that the 3.4l and the TRD supercharger are a winning combo and Toyota wouldn't offer it if it would damage an engine.

Seriously? That is a pretty naive statement. Why then would TRD come out with their own 7th injector kit to try and remedy the problem which they couldn't figure out and their kit was a complete flop which is why URD started making them. Having had one, my truck ran so bad I parked it for 8 months til I could afford the kit. If I kept running it I guarantee my motor wouldn't have lasted another 10k.

Were not talking apples to apples here. Yours being an 04 has a different fuel system (TBW) and therefore has less of the problems that the earlier trucks have. I Like the power mine has (although still underpowered IMO) but if I had to do it over I would have stuck with the stock system. So many more issues and problems that I would really not deal with although they have all been fixed with the urd kit.

Running a pulley will only multiply your problems. If you are having issues then the pulley adds more boost which will lean it out more.
Some trucks have no issues when slapping on the SC. Mine didn't for the first 2 years. The one day it switched and went to Sh!t. Not sure why but it is common to all of a sudden to have problems.

I've never owned one, so obviously I don't have the experience you have. I have driven several when I was looking to buy a Tacoma. I don't see how a factory engineered supercharger that is offered by Toyota would severely damage an engine. If there are issues with the 3.4 & the TRD supercharger combo, than that is a different case.

Like I said before, take the time to tune it right and keep the supercharger.
 
Also the TRD SC isn't from Toyota. May be part of the problem. I believe they come from Magnuson. I could be wrong though. They are the ones that service them and sells parts for them. Taking the supercharger off will lead to alot of disappointment. I have a 4 runner without one and so I often get ticked when the power isn't there while driving the runner.

I don't buy my truck because it was red ;)

When I found this combo my first two calls were my Toyota tech buddies whom had installed spasms of SC'ers in their dealership days and both and very accomplished techs. With their advise and my research I was confident with the setup. I've had a few throttle body issues potentially related to the SC but those are long behind me.

As for whom manufactures the SC, of course its not Toyota but they engineer it in house, I spent some time in Baja with the TRD engineers, very sharp folks and like motorsports folks. Head dude has a rocking SC'ed Tundra putting something like 500 HP to the rear wheel :cool:. Keep in mind Toyota doesn't make ujoints (Matsuba), tie rod ends (Joint Fuji), tires, sheetmetal (Araco), t-cases (Aisin), shafts (Seamaster), etc... They engineer them to their specs. All beside the point, the TRD fueling issues are a know issue on the early trucks. Hence why I don't ever recommend a SC to my customers with early 3.4's. FWIW (09/02-09/04) I.e. 2003 and 2004 models have the same TBW and injectors but a different ECU's.

Mine is an 03. Maybe I should meet up with one or both of you guys ( Lewis and Kurt) and let you drive mine and figure out what I'm talking about. I've learned how to drive it now with no problems but I don't want to have to limit or change my driving style.

Come buy some parts, I'd be happy to drive your truck and let you drive mine :D

I've driven a few dozen SC'ed 3.4's, 4.0's and spent a few thousand miles behind the wheel and co-driving in a SC'ed 1FZ this last weekend... I'm far from an expert on the computer/fueling interface but I can tell you if it feels right when I smash the pedal into the ground. Had a FULLY loaded 80 Series doing 95 mph near the Salton sea... not bad pushing 35's and literally loaded including several hundred pounds of gear on the rack. It felt right at home pulling :laughing:
 
The sticker says 8/03. Is that good or bad? I should be heading up there next week to get some new general grabber red labels. maybe I'll stop by then. I'd like some parts but I don't know where to start or what I want to spend.
 
Means its in fact a later 03' and I do recall reading that the last half of 02 models had the same fueling characteristics as the 04 models but my searches earlier showed that Toyota lists a different computer for all 03's and all 04's though both have the same TBI (APPS/TPS equipped) and identical injectors.
