Wondering if anyone has had a 4.0 liter Toyota supercharger installed by the dealer. If so, how much was it and do you like it?http://www.toyotaracing.com/trd/features/package_4_0l_v6_supercharger.html

I would check TW or XRU. Plenty of people have it and love it there. No one here has one from what I have seen.

My brother had a Trd supercharger in his fj and he loved it.

I drove a buddy's truck with one and I wasn't too impressed. It was more likely due to the fact that it wasn't my truck so I was being nice to it. If it was mine I would have popped it into 4wd and launched away.

Haha yeah I never got a chance to drive his before he sold it I think one day I want to turbo mine

I think I would throw a blower on my truck but I wouldn't go crazy with a bunch of work. I would much rather put go fast parts on a sports car.

I wonder what kind of gas mileage you get with one.

 

[whippersnapper02]

The same as long as you don't boost.

 

[tacomalimited]

Does it need higher octane gas? Or can you still use regular?

 

[OffroadTaco4x4]

It needs 91

 

[OffroadTaco4x4]

I think it can use 87 but you have power loss because of the ecu, so basically you do need to run 91

 

[whippersnapper02]

Definitely 91 or higher only.

 

[tacomalimited]

It needs 91

That's what I thought:sad:

Does the O2 sensor compensate if i use 87 octane?

Let me tell you first off don't use 87. Technically it is possible to use it but the ecu will mess with the timing to prevent detonation of the engine, so you will get power loss. If you got the money for a blower, you should be fine using 91 or higher

Normally the knock sensors watch knock. If any is detected then timing is adjusted to prevent it but boost changes that. You can only retard the timing so much to prevent knock and it comes easier with boost. Some engines with direct injection can compensate for it since the fuel is injected when it needs to burn and not before.

Simply put if you have boost you need higher octane unless you like the sound of popcorn and you like vent holes in your engine block.
