OK, are there any legitimate and/or proven performance mods for the 5.7 yet? Last thing I want to do is dump money into something that won't work. So if anyone is aware of a good performance mod for the 5.7, then please let me know. Thanks.

I've heard of exhaust and intake parts out, I personally don't think they give much power increase for the price they cost though. You're better off waiting on something that can reprogram the Tundra ECU, either that or wait for the "trd supercharger" that I hear about. I hope they don't drag thier feet this time.

 

[TNK]

Nope not yet
They have a few people getting their butt dyno tickled,but as of late nothing is putting anymore ponies in the pasture.Theres alot of hype over the TRD Blower due out late 07 but who knows.
Personally I wouldnt mind seeing a Turbo or even a new reverse turbo system for this DOHC platform.I think it would be a great pairing

 

[asianflava]

I was on some dealership website that had TRD exhaust as an option. Don't know if it was for the 5.7 tho.

 

[Toreadorranger]

Yea my 07 came with the TRD exhaust.

That would be very very cool.

Reverse turbo? I've never heard of that one. What does it do, suck the exhaust gases out of the cylinders instead of using the spent gases?

Common, everyone knows that a reverse turbo only works when you are in reverse gear. It's for when you want to back up very very fast.

Intake, Exhaust and a Dyno tune could net up to 30 WHP if done properly. I'm waiting for another member here to dyno an intake and compare to stock (or stock with exhaust) to see the gains -- I don't imagine its going to make huge power but I'll be interested to see.

I agree with what everyone else is saying; if TRD is serious about the blower for the 5.7 that is probably your best bet. I'm looking for 500 HP:devil:

I checked with Uni-chip and they have a hard wire cpu upgrade at a local certified dyno. Cost $$$$$$ or wait till the plug-and-play is available at the end of the year.

Sounds logical to me.

So Uni-Chip is making a plug and play for the 5.7 huh? Any idea what this will cost or where I can read up on it? Thanks.

If their past products for new vehicles are any indication, be prepared to pay around $900 for less than 10 WHP...

I almost bought a Unichip for my 4Runner before I realized that I could do the same thing with a generic "piggyback" and custom fuel map tune on a dyno. Unichips are WORTHLESS without a dyno tune because their "maps" aren't specific to your vehicle (mods and sensors), location or driving style.

I've mentioned more about custom tuning fuel maps in my air filter thread. I may or may not do the same thing to the Tundra, I'm waiting to see how much power a CAI makes before deciding. :tu:

Had a friend at the stealership call uni-chip. All they could tell me is a plug and play by the end of the year. Spoke with a local hot wire dyno shop and they quoted me around $600-800.

Is there such a thing as a reverse turbo or have I been taken on a snipe hunt? :ts:

 

[sergtech]

Thundera, 30 WHP? You really think thats possible from intake, exhaust, and tune? I really don't see how on the 5.7. maybe 15 tops. But it would be great if so. Only thing is that the truck getting these mods would have to get dynoed completely stock first. Then dynoed again after the mods on the SAME dyno to prove any acurate gains. Is your guy doing this?

 

[GGWOODY]

No, no snipe hunt at all...I installed one on my tacoma....I also have carbon fiber muffler bearings, and dual inverted carb, 360 degree tracking gling rods, and I have also added laney grometts to all 7 cylinders.

actually it is real. Look up STS turbos. They make remote mount systems. They mount under the back of the cab or the bed.

Let me refrase that, not sure if a remote mount is considered a reverse turbo by some.

[TNK]

Yes they are in fact referred to as Reverse Turbos by some.(Sorry for the typo above )
This setup is to freaking simple to believe and yet proven as claimed for sound performance.

All the spool-up haters(turbo-lag) please dont bother trolling this issue. In a Tundra platform you'll be grateful it doesnt all hit at once. Pickups dont respond well to power adders unless some pimary traction issues are addressed prior to boost build ups.

So all the TRD fans best consider cost effective verses label trendy.
These turbo setups will smoke anything TRD will offer the public.Even with add-ons like injectors upgrades and tuneing,labor etc.,one would still be WELL UNDER the projected $7K for the TRD Blower.

DOHC motors and Turbos have alot in common,both pull steady up thru the RPMs without dropping ponies out/off at peak levels.
Plenty more but ........:tu:
