Stevinson Toyota East in Aurora, CO has created this Tundra to showcase their customization skills.

The supercharger mounted on Stevinson East’s All-American Tundra.

When we got their, Ryan Prue and Tanner Tilton were finishing up the install. After dropping the fuel tank and putting in a new high flow fuel pump (and adding some 91 octane gas), they double checked everything and flashed the ECU. Then, it was time for a test drive.

No traffic laws were broken – we swear.

We’re going to visit Bandimere speedway next week with the guys from Stevinson East and participate in a few 1/4 mile runs. We’ll keep you posted. By the way, Stevinson Toyota East isn’t selling the truck they’ve made (at least not yet). If you want one, however, they can build you one for about $30k. Pretty cheap for such a fast truck…

NOTE: This was written prior to news about the TRD Tundra Supercharger Specs – it’s still interesting background info, so we decided to post it.

The evolution toward the 5.7-liter supercharger is truly intelligent design. TRD has developed horsepower/torque pushers for the 2000-03 Tundra, the V-8 Tacoma, the Camry Solara and Scion tC and others. Tundra watchers knew it was just a matter of time before the wizards addressed the big ’07 Tundra. Then at the November 2007 Specialty Equipment Marketing Association (SEMA) Show in Vegas, the concept Tundra Double Cab was spotted with the supercharger and air-to-liquid intercooler generating “approximately” 500 horsepower – no estimates on torque increases. Since the Toyota booth display vehicle was attached to a 10,200-pound gooseneck car hauler, the extra power had to be more than simply wishful thinking. Two months ago, the 5.7-liter supercharger surfaced on a Sequoia – the SUV that shares its iForce V-8 with the Tundra.

So, given the information available, what manner of beast will the Tundra TRD supercharger be? We know it’s an Eaton-Roots-type, or positive displacement, supercharger. The patent dates back to 1860 when Philander and Francis Roots used the technology to ventilate mine shafts – an interesting tidbit to toss out at your next barbeque. When automakers were faced with upping performance by increasing engine size or engine efficiency, they opted for efficiency. The concept of a blower was incorporated into automotive engines in the early 1900s by Gottleib Daimler and by the 1920s, appeared in racecars and premium autos. Eaton-Roots type superchargers are reliable, nearly maintenance free, and eliminate drag on the engine when the boost is not required.

Fast-forward to the TRD 4.0 V6 supercharger, the presumed “Mini Me” to the 5.7 V8 TRD supercharger. A reasonable way to anticipate the features of the 5.7 unit is to look at those incorporated into the most recent TRD performance upgrade. The 4.0 was the first TRD model that included an intercooler and Toyota-supported reflash of the factory engine control unit (ECU). The inclusion of an intercooler reduces the inlet temperature to the engine and allows more aggressive ignition timing. The bottom line with the beefier TRD superchargers is improved engine response, increased power output, better resistance to detonation, plus a safety margin under heavy duty use. To rebalance the air/fuel mixture, the 4.0 blower includes high flow fuel injectors and iridium spark plugs with a slightly colder heat range than standard plugs. The fuel pump and fuel pressure of the stock engine are the same. A significant first for the 4.0 (and presumably a feature continued with the mythical 5.7) supercharger is the integration of the factory ECU recalibration allowing for very precise settings based on the performance components and power increases.

Okay, all this guessing in anticipation of the 07-08 Tundra supercharger may be a new form of cruelty – like a big carrot dangling just out of reach. But with any luck, in less than a week or two, the 500+ horsepower Tundra will be ours.

Here are the official specs: The 5.7 with the supercharger makes 504 HP and 550 lb-ft of torque. The list price for the entire kit is $5,875. Dealer cost is about $5,000 (but good luck buying one for that).

The total cost (including installation) is going to be around $6,800 – based on a labor rate of $105 an hour. If you’re trying to get a better price than MSRP, try negotiating off that installed price. Maybe the dealer will knock a little off since you’re doing the install with them.

Features:

• Unique design fully integrated into the engine with the latest generation Eaton® Twin Vortices System (TVS) roots-type rotor pack.
• The twin four-lobe rotors feature 160-degree twist improves air-handling, noise, and vibration characteristics

Kit includes:

• High flow fuel injectors, single belt drive, and lower heat range iridium-tip spark plugs.
• Water-to-air intercooler system with a custom low temperature radiator (LTR)
• A new performance air Intake system is included in the kit with a TRD re-useable performance filter, Intake Flow Accelerator and a larger upper air box lid with a filter service gauge.
• 50-State emissions legal.

Power: 504hp up from 381hp / torque 550lb-ft up from 401lb-ft.

Installation: Installation time is approximately 9 hours with the first installation likely to take longer. Installation instructions are available on TIS. To aid in installation , TRD has developed a hoist mounting bracket that bolts directly onto the supercharger housing lid. The bracket is made from stamped steel and plated to prevent rust (PTR25-34070).

Engine calibration reflash is available through TIS using your scan tool or TechStream device. No other special tools or adapters are required.

Warranty: Warranty is the same as other TRD powertrain components: 12 months or 12,000 miles or the balance of the 5 year/60,000 mile new car powertrain warranty, whichever is greater, when installed by an authorized Toyota dealer. Superchargers installed by anyone other than an authorized Toyota dealer are warranted for 12 months or 12,000 miles. Specific warranty information is included with the supercharger

Sales Notes: This TRD supercharger is to be sold only as a dealer installed or over-the-counter option after retail sale of the vehicle. This supercharger may not be sold to the customer at the same time as the new vehicle and may not be financed together with the new vehicle.

Maybe.

As I’m sure you’ve all heard by now, the TRD Supercharger has been given a part number in the latest Toyota Accessory Guide (part #  PTR29-34070), but that’s no indication that the supercharger will be available soon.

However, I spoke to a friend of mine that works in a local Toyota dealer’s parts department, and he was estimating he’ll be able to order in a month or two. That would mesh with Toyota’s stated time line (see the picture below), but that’s not really any indication either.

My guess is that the Tundra 5.7L TRD Supercharger will delayed — it’s pretty common for these things to be held back by either the EPA, CARB, or the internal bureaucracy of Toyota. Take, for instance, the debut of the supercharger for the Scion tC. It was supposed to be out in the fall following the car’s debut (it also had a part number in the catalog), but EPA and CARB regulators held back the release more than 6 months. Same story with the Tacoma supercharger back in the day (and the one that’s supposed to be coming out).

But, it’s cool to imagine getting our hands on one…
