TRD Supercharger

[DakineTX]

I doubt Toyota would sanction let alone bring out (with TRD) a supercharger if the engine could'nt handle it OR the design had 'extra's' to facillitate such an add on.

Why supercharge a truck? Why supercharge a car (unless for pure racing, as there IS a speed limit), just some have this as a passion/hobby me thinks.

As for a gas engine being silly to put forced air induction on, hmmm, I was'nt born in this country but believe ya'll have had supercharged gas vehicles for a VERY long time indeed. In europe turbo is more favoured but the gas exchange is still the same desired effect.

A turbo or supercharged diesel truck is for a reason (usually) other than speed/performance. I would say if TRD bring out a SC for the Tundra they KNOW the engine will handle it, otherwise (as it will be a warranty item) they will be shelling out for alot of new engines!

A high compression NA gas V8 is a pretty silly engine to put forced induction on in my opinion. Unless you plan on rebuilding the bottom end to handle more boost and plan to add a nice big intercooler for the charge air, you are just tempting fate to detonate your motor.

There's a reason that every sport truck ever made has been a gasser....sure, an oil burner is easier to bomb but you still end up with a near 8,000 pound pig.

And while I have no scientific data to back me up, 900 pound feet of slow revving paint shaker in a 3/4 ton performs like 500# of torque in a 1/2 ton gasser............probably both be 12 second trucks but one would actually be able to stop and actually go around a corner.

So while you think fast trucks may be "beyond you" (my '04 Lightning made me giggle more than any vehicle I've owned) .....a fast diesel is even futher out there in practicality

Like already stated (in other threads also) Toy is not going to market a kit, which will be warranted when dealer installed, that will grenade motors.

You're right though, start messing with bigger lower pullies and different tunes and all bets are off.

I have a Duramax and it weighs 6600 pounds so I don't know where you get your 8,000 pounds from. As far as "slow revving" goes have you driven a modded diesel lately? Absolutely nothing slow revving about the newer ones. The cool thing about a diesel is for relatively little money my truck is very quick and I can still tow about anything out there
I had considered putting a TRD charger on my Tacoma but changed my mind since i'd never keep my foot off the accelerator, if Toyota puts a charger out there for your 5.7 it will probably produce boost well below it's potential only because it will be warrantied. I'm sure one of you guys will blow off the warranty and see what your trucks can really do Your trucks definitely have the potential to be quick!

This is true with the turbo diesels. They can make tremendous power with $5K. But Toyota could produce a nice twin-screw supercharger or better yet-turbocharger that is low enough boost whereas it does not blow the bottom half of the engine. The hardest part on their list is to also cover this under warranty. Does anyone know if our motor has 4-bolt or 6-bolt mains?

Two buddies own Dmax's...........if I HAD to own a diesel, that is the most gasser like of the bunch (I have to suffer driving Ford PSD's at work Code 3 most of the time....and I'm a Ford guy) But even the Dmax has what? A 4,000 RPM redline and is not as quick revving as a gasser. (a guy on another site says they're spinning 'em up to 4,400 now after certain mods)

And you're correct, the high 7,000 pound trucks are the Fords and Dodges, I was surprised and impressed that the GM's are at least a 1,000 lighter. (pickuptruck.com's shootout)

But the 3/4 ton GM's are still at least 1000 pounds + over the 1/2 ton Toy's.

No doubt if I needed to tow over 8,000 pounds, I would have skipped the Toy alltogether.

If you go to the TRD site they appear to already have a P/N referenced for it. If we use some of the other SuperChargers as a guide I suspect it will be more than $4000 plus $1000 if you choose to have a dealer install it.

i'm pretty sure the p/n is PTR29-34070. i was looking at it when i was looking at the cai.
and if we go with what the concept sport truck had. it'll be an eaton roots type supercharger with an integrated air to liquid intercooler.

I think you are missing my point, and so is everyone else. I am not saying that adding forced induction to a gasoline engine is stupid. I own a turbocharged gasoline powered car right now. It was designed and built to be turbocharged. You know, low compression pistons, integrated computer control of boost and fueling, fair sized intercooler. The motor has the safe potential to make quite a bit more power/boost than it does now, and has a wide safety margin of avoiding detonation issues.

Taking a high compression gasoline engine and adding boost is not a good idea from a durability standpoint, and it leaves you no other room for further power upgrades. You can't blow much useful boost on a gasoline engine with 10:1 compression, and to get any solid power out of it, you still need to cool down that charge air. Otherwise heat soak from continuous work will make the engine management system pull timing and fuel after very limited bursts of high power. Not exactly real useful. All of your high performance supercharged or turbocharged engines start out life with bottom ends made to allow for boost. There is a reason for that.

Just because I don't see any reason to try to make a truck go fast in a strait line, doesn't mean you guys aren't free to do so. However, if that is your goal there are better options out there to build on than a high compression gas V8 (unless you plan on building up a small block or big block Chevy). Turbo diesels have an advantage when it comes to modding them for more power. They already have a turbo, intercooler, and motor designed/built for boost. Your performance dollar will go further with one of these, and you have a superior forced induction system compared to a supercharger to boot. Turbochargers are way more efficient, don't sap power from the motor to be driven, and on a diesel will not hurt your fuel economy under normal driving even with performance mods.

I think everyone gets your concerns...........you won't accept that they are unfounded with a mild upgrade.

One very quick point, the Tundra even with its rather high CR still runs on regular fuel.

A very efficient chamber and aluminum heads allow this.


Ford Lightnings did NOTHING to their bottom ends to run the extra 130HP when blown. (they did run a lower CR piston)

(original 5.4's ran forged cranks till aprox. '01 went to a cast crank after while the L kept the original crank)

You're also not grasping that NOBODY is arguing the power levels that an oil burner is capable of.......I, for one, don't want that nose heavy package.

A RCSB Tundra is under 5,000 pounds and could be very Lightning like with the right dampers/tires. A very decent handling vehicle that can still tow modest amounts and carry some payload when needed.

What's weird is we sold the Lightning for a Mustang GT (a high compression V8 that is reliably supercharged regularly with a warranty from FRP or Roush)

Now we're talking about selling the Mustang to get a RCSB Tundra.......with a blower.

[and deep down I'd also like to S/C my Crewmax]


You did lose me on the "(unless you plan on building up a small block or big block Chevy)." comment.

[DakineTX]

I had a SUpercharged Harley Supercrew. It did not have some of the internals that the Lightning had but still I had zero problems.

Point here IS, we ARE talking about the Supercharger for the new Tundra. NO doubt building your own engine for performance IS much better BUT that is not the topic here. Some of us are interested in the stuff we can do to these trucks.

Basically, no it's not a perfect situation BUT it IS an option and due to TRD offering it it WILL be warrantied and after seeing the rest of the trucks build I would hope the engine has been built to withstand whatever supercharger TRD produce.

I just bought two Tundras and do not intend to buy a car to mod at this point. Just am enjoying these trucks.

As for Turbo (with regards to gas engines), I am from the UK orig. and over there superchargers are near non-existant and turbo is the norm. In my experience (although only owning 1 supercharged vehicle but many turbo in UK) I would take SC any day if for nothing else than to negate turbo lag (which is present on pretty much ALL but the newest designs). Also, IMO turbo's are a royal PITA to work on yuck!

[Burger Steak & Eggs]

I wonder what a regular cab 2WD stripper Duramax weighs.

[tundradreams]

I had my parts manager plug in the part number the other day. Price was over $5,000 for part. Don't guess I'll be getting one.

A little bit of background on me, before I went to work for BNSF I worked for a Toyota, Lexus, BMW dealership in Springfield, MO. The dealership performed several supercharger installs on the V6 Tundra at the time (previous generation) and the previous generation Tacoma. Of those installs I recall only about 70% of them were still reliable after the supercharger was put on. Toyota would still fix it of course, but the trucks were no longer worry free trucks. I don't know if our service techs were screwing up the installs, or if the package was just no good. Either way, pissed off owners was the result. So I am not a big fan of TRD engine parts at this point, they overcharge for the parts to cover the reliability issues the parts will cause. Everyone is really optimistic about "Toyota wouldn't release a supercharger if the engine couldn't handle it". Toyota is in business to make money. They will release it at an inflated price with plenty of margin left over to cover what percentage of the kits they predict will be troublesome.

There is a reason TRD superchargers have never been offered from the factory. They cause higher rates of reliability problems, not only in the engines but the drive lines as well. How much torque is the 6 speed auto rated to handle? For those that don't need a super reliable daily driver pick-up go ahead and put on that overpriced TRD supercharger if you want. Just don't be surprised if the part never makes it to market, it may not be acceptable at all for Toyota reliability wise.

On the last comment, if you were going to use a high compression V8 to build up for a high power engine without lowering compression; I would build an SBC or BBC and leave it NA.

I don't question your experience and a 30% problem rate is unacceptable....but let me run a total hypothetical by you:

How many of those 30% were screwed with by the owner? Smaller top pulley; bigger bottom pulley; too aggresive of a tune....then when it fragged, it magically made it back to the shop totally "untouched".


One of my buddy's Duramax fragged.....of course it was bombed pretty decently. Magically it made it back to the dealer in stock condition INCLUDING a new manifold where he had to remove the one he tapped for the EGT guage pick up.


Your opinion is based on a lot of knowledge.........but right now all of us are speculating, and we'll know shortly which way it'll go.


BTW, I'll see your Chevy and raise with my 4 bolt Cleveland block(s) and future CHI or AFD heads (at 408").....

[Wildbill Tundra]

what kind of power will this thing make.....I would ateast hope 100 rwhp....That would be great and still warrantied
