2009 Supercharger Tacoma DC

Well the long wait has finally provided some fruit. I purchased my Tacoma DC short bed a few months ago and have been patiently, or perhaps impatiently, waiting for Toyota to get the parts, super charger, into their system. TRD completed all the approval processes for the emissions back in November and had started shipping the parts out. However, the dealers could not access the inventory until early January under a limited release program. Well… anyway I was able to get the dealer to order me the supercharger and fit kit for the 2009 model. The 2009 is different than the previous years as they moved some of the components around such as the intercooler pumps, etc. and in doing so it would seem that they had to have a new emissions map created and approved, thus the long wait.

The parts arrived to the dealer last week and I scheduled an appointment this week for the install. The service rep said that the install would take two days, which I could not believe, but what was I to do or argue against. I think it took two days because the tech did not start on it till mid day and it’s a full day install for an experienced tech.

Day 1 - After day one I drove to the dealer to see how it was looking. Thinking back I should have snapped a photo of the parts all over the place and manifold removed. To say the least, the tech had removed a lot of the top parts under the hood. The tech was diligently reading the install manual when I arrived so I did not want to distract him too much. Was not sure how many times he had done SC installs before but it was concerning me. Disappointed with the amount of work that I could see being completed for the day I left with anticipation of a great day tomorrow when it was all installed.

Day 2 – I returned to the dealer with a ride from a friend so that, with the install complete, I could pick up the truck. I gave it a quick look under the hood to check out the work and look for anything of concern. The new equipment looked really nice, the only thing that was a distraction was the fact that he made what use to be a very clean engine compartment, somewhat nasty with water spots and coolant all over the place. UGG! The truck only has 2000 miles on it. Come on man… keep it clean. Oh well I will have to spend some time on the weekend cleaning up his mess.

The new system requests the use of premium fuel vs. the regular as the truck started with. I knew about this before hand so on my last tank of unleaded regular I drained it down as much as possible before refueling with super.

With the system reading from fuel to engine I was ready for some test runs… Well to say the least the city streets make it more challenging for a fuel open throttle run up with speed limits littered throughout the city ranging from 35 – 55. The other challenge was not having other cars in front of me so that I had full open-street with which to "punch it". Eventually I found myself in the ideal street situation, strait and empty. The first run was 0-40 and it was quick. I tried to time it but it was too much to time and drive at the same time so I will have to follow up on that later. I managed to get quite a few small runs in ranging from 0 – 60 on the local streets.

The next morning I was able to get some freeway time and managed to get a 0 – 80. WOW! Ok the little runs were cool, but the full 0 – 80, OH YEA!!!!

The system was quick and the acceleration was fast. I will for sure need to have someone run with me and time it out.

Some things that I noticed about the overall system and experience were the following:
1. The automatic transmission is not the best for this type of application as sometime if I had any forward movement it would shift into 2nd gear which made punching it, down shift and go back to 1st. Once that happened it was a launch of power. In a manual you would still be in 1st and launch would be immediate.
2. The super charger whine. The documentation that came with the super charger describes the whine of the system as a normal function and not a mechanical issue. The whine is described as the systems blower component or otherwise described as the system that compresses the air prior to injection into the manifold system. The whine is not noticeable during normal passive driving and only manifests itself when higher engine demand is requested with more pedal pressed. IF you drive passively you may never actually use the power of the SC its only when you push the pedal down more does it kick it up several notches.
3. Gas mileage – I have no idea what all will happen with the gas mileage and super charger combo as my first few tanks of gas are set to burn at what ever rate the system will give me the most power possible. I plan on stepping on it as much as possible over the next few tanks, after all isn’t that what a super charger is for anyway, hauling a!

I'll follow up with some install pics for everyone and some gas mileage updates as the tanks burn through the system. In general the stock DC v6 provided just under 20 mpg under normal conditions for me which included city and hiway driving.

So to sum up this article, which ended up being much longer than I thought it would, the 2009 Tacoma super charger system is outstanding! The power is awesome and the system was well worth the wait.

Some descriptions on the photos

1st one shows an nice overall close up of the supercharger and its intake system along with belt layout
2nd photo shows one of the added radiators for intercooler fluid and some misc tubing
3rd is a shot of the actual intercooler and the tubes that are going to the radiator located in 2nd photo
4th is a misc shot of a part of the intercooler. Not sure what it all does...
5th is a misc shot of some of the wiring just below the SC on the right side of the motor
enjoy!

 

Impressive. throw up some pics and videos of the runs.

 

Another boosted 1GR.. NICE!!!

You think its quick now.. Put a CAI on it, and it will really open it up. I recommend getting an AFR gauge and a wideband. The TRD Re-flash is a hit and miss. Some trucks get tuned perfectly others too lean or too rich

I would get an idea of where your truck sits before you go pushing it real hard.

 

how would you suggest re-tuning in the case of too lean/too rich? URD maf??

Just trying to get all the info on this i can.

 

I will have to check on the tuning of the system, was not aware of it. Perhaps that was the dealy in the new emissions map to fix some of those previous problems.. I have been looking for some type of scan tool to see those outputs from the computer including how to changing the door locking options on the vehicle. The owners manual does not show how to change the door programming, but others seem to have done something similar on previous year models through a sequence of door and ingntion key turns..

 

The URD MAF cal will work, but for this kind of application you are better off using a more powerful application. I HIGHLY recommend the APR X-1. It was designed specifically for the 1GR motor, by some very respectable engineers. My next suggestion would be the Map ECU 2 then URD Maf Cal.

There are some tools out there you can use. But a wideband you could hook up, place in a gauge and have it always available.

 

So I have not posted photos before but looks like there is a limit. Would be nice to see how I can add text between the photos to help explain what the image actually is. Anyway, here are some more.

The first photo is of a device just forward of the battery. I do not recall it as a standard item.

2nd photo is of the new pully and belt routing. This supercharger requires a different belt design and as such additional items.

3rd photo is of the additional radiator that is added to provide cooling for the intercoolers pump. This device lowers the intake tempature of the air.

The 4th and 5th show pictures of the intercollers pump. Its locate just above the front bumber behind the grill.

Enjoy!

 

A follow up on the previous posts... I attempted to do some test runs with the truck and timing my 0 - 60. Its was not the easiest things to do but here were by three times as best as I could get them.
run 1 - 6.17
run 2 - 6.09
run 3 - 6.06

Don't take the times as gospel as driving and working the clock are not the easiest things to do at the same time when the truck is lurching forward at full speed. From what I can read elsewhere on cars.com the standard 0-60 stock speed is about 7.38 so I would say this was a nice increase.

On a side note it was a total pain in the a$$ trying to keep the wheels from totally peeling out when I smashed the pedal down, there is just a lot of power coming off those wheels.

 

Try loading some photos onto a website like photobucket and copy and paste the IMG code to make the photos larger and then you can just type the text inbetween the photos as you load them.

Looks great by the way. Keep the updates coming and great job!

 

Another follow -up Seems that the truck is running a little hotter in water temp than before. I am not sure if this is a result of the additional radiator they installed as its in front of the main engine one...

 

sweeeet...

 

What is your water temp at?

 

Im not sure but the indicator on the dash seems to be a hair higher than 50%. For some reason I remember it somewhat lower before the install.

 

You should get your self a scangauge 2 or similar. My guess is your water temp is probably between 184-188* which is about normal. You could invest in the X-1 kit and get the 170* T-Stat.

 

That is so freakin' awesome! You are a very lucky man.

 

What the supercharger set you back if you don't mind me asking? Looking to get one this year just didn't know it was available already!!!!! Sweeeeet set up!!!!

 

I am not sure what the retail on them are but I negotiated my during my vehicle purchase. I was able to get a price of 4100 installed plus tax which I feel is a very good price. I beleive the retail on the box with fit kit may run around 4800 plus install but I cannot be sure. The 09 fit kit is different than the 05 - 08 years in ways that I am overall not sure about. I do know a few things. For example, they had to get a new emissions map approved as a result of the new fit kit. This may be due in part to some of the other posts I saw regarding mixtures being too rich or too lean. I understand that some of the componets of the fit kit may be installed in different areas vs previous years. My buddy would be able to tell me more once I show him the install, he did several of them in years past.

I was trying to post a video of the run along with a nice sound clip, however the file extension is apprently not compatable with this forum. I will need to covert it over to an mpeg then post it.. maybe later today. Sounds nice..

 

So I have been keeping track of the gas mileages to see how things were pre and post install. Of course Driving habits and my ability to request full open throttle from the truck effect its MPG. Anyway I will update this post for the first few tanks of fuel so all can see the estimated MPG pre and post install.

Pre install - ~20mpg average driving
Post install:
Tank 1 (first tank after SC installed) - Unrecorded. Mostly due to the fact I was pounding the accelerator at each stop.
Tank 2 - ~16.7 mpg (mostly agressive driving w/ some moderate)
Tank 3 - ~18.8 mpg (passive driving as best as possible)
Tank 4 - ~17.9 mpg (mix of fun and moderate driving)
Tanks 5 - 8 ~18 mpg (Mixed driving - I just cannot keep from smashing it at the light and dusting the others) Forgive me

 

Tank 5 should be light throttle just to give an idea of how it runs when the charger is used barely. It would be interesting to see.
