Is the 4.0 Supercharger worth it?

I'd do it again, but $5k for 100hp may not be worth it for some people.

 

You gain 100 hp even with parasitic loss?...can't be true

 

Are these engines still reliable with the super chargers installed? As fun as the extra power would be, I wouldn't want to loss reliability .

 

It's more like 60 it takes a lot more than just the SC to get 100.

 

After all the stock TRD supercharged 4.0's I've driven I'd say no, they really don't pep up like the 5.7 tundra s/c.

I have yet to drive a tacoma with a URD upgraded s/c but I've driven an FJ with the 7th injector upgrade and a pulley.

That said, they are more reliable with the supercharger than most engines, I've yet to see a supercharger kill a 4.0, but I've seen two 5.7's die from factory superchargers.

 

That sounds better...just keeping it honest

 

Even if just the SC alone made 100 it wouldn't be worth it to most people.

 

Not to me...but some people like that.

 

Like I said, I'd do it again. It's definitely an improvement especially on the freeway.

 

I just upgraded to a 5.7 Tundra when it wasn't enough...makes the supercharger sound cheap

 

So yeah I actually was- funny story I had called the tire shop and decided to give the Rugged Trails a send off. Afterwards I found out that the tires where two days away so I had limp around on a tire showing its cords...the spare you ask? I had cut a side wall off roading and it was already dead too. good times!

 

Two of my neighbors just bought new Tundras. Both of them are lifted. They're freaking huge. I have no need for a vehicle that size. Extra power is nice I'm sure but those are some big heavy bastards too. My Tacoma is the perfect size for me.

 

I agree. I sold a 2500 Dodge with a 5.9 Cummins when I bought the Tacoma. This truck does everything I need from a truck right now. Not going back to a bigger truck, unless I need the payload and even then I would go 3/4 ton or larger....

 

I agree they are huge...I kept mine stock...and it's still huge! But shut off the nannies and the TC..it's a muscle car. I own and have owned LS swapped C10s....it would eat them for breakfast. Pretty good for a NA vehicle. It does suck to find parking though

 

SC is rated at 69hp after parasitic loss by Toyota. Add the 2.85 pulley stacks on another ~15 or so.

Also worth noting, the parasitic loss is 1/2hp when not in boost as the 2nd gen supercharger has a bypass valve for better efficiency, which is why effect on mpgs is minimal.

 

You sold the best dodge...with the best moter they ever put in them.

 

So your saying....I was right?...it's not 100

 

It was a great engine but maintenance costs didn't justify keeping it. Price a set of injectors for the 5.9 and you'll get an idea... even oil changes are 4+ gallons of oil.....

 

back down to the tire store for that Taco!

 

Yup my brother has one 600,000 still running...everything else is falling apart around that engine.
