Flex Fuel and The 07+ Toyota Tundra Supercharger Systems.

Over the last few months we have been testing and developing the ability to supercharge the Flex Fuel 5.7L Toyota motors using as many OEM parts as possible to complete the transformation.  We are proud to announce that we are now there and selling these kits as installed options only. So pop the cork off the champagne and lets celebrate with some horse power! 

This all started last summer trying to shop for a Regular Cab short bed Tundra.  Personally I think its the way all pick up trucks should be, but understand the reasons for back seats as well.  Finding a RCSB tundra is like finding a needle in a hay stack.  At any given time there are 1000's of Tundras on the market for sale,  The number of them that are regular cabs are is in the teens at any given time.  Make it 4x4 and short bed.. maybe 1 or 2 for sale.  To make it worse, most are flex fuel 5.7's and I always wanted the supercharger on my truck.   I searched for months to find a low miles RCSB 4x4, Non Flex fuel Tundra...  At the end of 7 months, I passed on the idea of supercharging the truck and purchased a low miles 2013 from Oklahoma that was a FFV truck.  

As soon as I got the thing I planned out a mod path and purchased the blower unit to see where we could get.  I have read that all kinds of other stuff was needed but I was up for the challenge.. even if it meant a no go on completion and selling the supercharger on to another lucky tundra owner that was not FFV. 

We sent the truck off to the Dyno and posted 317 WHP and 371 FT/TQ stock. Which was no slouch for a light weight regular cab.  The Truck posted mid 6 second 0-60 pulls from stock and even a bit quicker with the 4wd turned on.  Then it pulled into the shop and did not emerge for 5 weeks... Waiting and working on this was both fun and exciting.
5 weeks later the truck emerged..  Here are the results.... 

A truck that drives smoother than it did stock. 
The throttle bounce issue is diminished. 
The hunting for gears on the highway is gone. 
So far MPG has totally been un-effected, yet you do need to run 91/93 octane fuel.
 
The truck threw down after install 456 WHP and 478 FT/TQ  with an AFR of 11.6  So even with these numbers we are conservative on the AFR side.  If you use the Stock Toyota HP/TQ figures and drive line loss to the first set of Dyno numbers, that is 546 crank horse Power and 573 Crank TQ ! ! !  Because we are using custom tunes to get this system to work we are able to see more power than the factory non FFV trucks are putting down.  Its one hell of a ride I gotta tell ya.  The rear wheels don't get traction until it shifts to 3rd gear at 65-70 mph.  The 65-100 mph pull is nuts and rivals most muscle cars that I have been in for sure! 

So if you have been totally disappointed by the fact that you can't supercharge your Tundra 5.7 because you have the FFV motor.. Think again.... and then give us a call.  Kits are ready to be installed as well as several happy customers enjoying the extra grunt from their Tundra.  Even 2014+ Customers.


Mod List:
2013 Tundra RCSB 4x4 3500 miles
Wheels:  Konig BFD 18x9 +12 Off set
Tires: BFG K02 35x12.5R18
Exhaust, Corsa Sport, custom bent
Front Lift.  Fox Factory 2.5 adjustable Coilovers, Icon upper control Arms.
Rear Lift. Ekstrom Designs +2 Shackle Lift and Fox Factory 2.5 RR Rear Shocks
Extras, Roll Top Tonneau, Bed Rug, LED head light upgrades and Sport Grill.

See Below for 0-60 Run, keep in mind that 12% speedometer correction is needed from the tire change, so 55mph reading translates to a 60.5 mph ground speed :-)  4x4 0-60 times is right around 4.2 seconds flat.

That's awesome. I have a supercharged flex fuel tuned by Unichip, but my local tuner won't tune it any leaner than high 10.0s on the AFR, it dynos 437 to the wheels. Can you tune a Unichip without having the truck there? It's a awful long drive from California.

Can you still get SC's and if so what would be total cost to add to 13 5.7 Flexie?
