I'm imagining a full TRD build (Cold Air Intake, Exhaust, Supercharger), and I'm trying to find an estimate of total gain in power/torque at the wheels. Could anyone help me with that?

And does the exhaust give any gain at all? I couldn't find something to really clear that up for me. AND am I missing any other TRD performance parts (other than suspension mods), as far as I know there are only those three. Thanks for the help!

TRD exhaust is an axle back, no gain there. Cold air intake doesnt work with the SC unless you mod it.. and probably wont make much difference anyway, even with boost. So you are looking at the normal SC gain for power.

 

^ Ditto. SC is it for TRD power... and if I recall, some people were getting nearly 200whp from just the SC, so that's not terrible really.

If you want a different sound, then go for the exhaust... but there are a LOT of axleback exhausts out there if you just want a different sound (there's a thread with a lot of videos in the Drivetrain/Power forum). So listen to as many as you can before you get anything.

Even if you replace the ENTIRE exhaust (header back) you're not going to get incredible gains. Maybe something in the neighborhood of 10-20whp or less? And that would be for anywhere between$700-$1000 in parts (or more).

YMMV though.

 

Okay, thanks for the help guys. I was only curious really, just trying to imagine what it would be with full TRD equipped motor.

My friend's tC (John) has the TRD supercharger, and (I believe) a CAI (TRD) on the engine. I'm not entirely sure though, because he doesn't show it very often to me. He'll be losing the supercharger soon and the CAI; he has plans to turbocharge it instead. From the numbers he's been telling me, it sounds like a ZPI Stage 0 (230 hp, right?).

Anyways, thanks again!

 

we had the exhaust right from the start, and added the sc as soon as it came out. Now TRD told me the exhaust was good for several hp, but i'm sure that isn't the case. We just liked the sound of it compared to other versions ( especially after 30k miles on it ). TRD offers a cai for stock, but it does not work with the sc ( in fact they hit the no-warranty card if you put an intake on the sc ). Though i was told by a regional rep that the new xb ( w/ our motor ) will have the sc as an option, and he thought with the cai as well--which makes me wonder if at some point it finally will be come avaiable for our sc's. Our dyno #'s were in the 190's, which is fine for us right now...... for awhile...... until.....
but we won't knock our components--they delivered what we expected.

 

Thx for the info. I was debating on whether or not to s/c my tC. Are there any other kits for s/c'ing other than the TRD? Could anyone give me some links?

Until I see something better than the TRD s/c, I think I may just go w/ a nitrous bolt-on, but I need to do more research for that.

 

Most of the dealers will try to claim that the TRD exhaust adds HP... but that's pretty much a no. I mean certainly not anything noticeable. Maybe 1 or 2 whp... but unlikely. But ya, does sound nice.

 

No other superchargers... just a bunch of turbo kits.

 

Bummer.
I was hoping.

I guess if I add anything on the motor, it'll probably be nitrous then. That way I can keep the fuel economy w/ a little bit of fun when I want it.

 

i've never ran a car that had nitrous ( my disclaimer here ); but i'd suggest some homework on that before you choose it over a sc or a turbo. Not just for any warranty implications, but overall motor concerns.
Again, no experience with it, but i've read enough that i'd research before ever using it

 

what is your goal as far as power? if you really wanted, to, get the trd supercharger, monster motorworks short ram intake, headers and s-pipe, and a full s-pipe back exhaust. put on a 9 psi pully and get it all tuned with a piggy back ecu like unichip or emanage or even a standalone. you could make some serious power like...250 whp.

now it is easier to do that with like a turbo kit, and usually safer since the supercharger has alot of problems and those mods will void the warranty. but it is something to think about.

 

TRD stuff is well overpriced. The s/c, i think, is worth it. the intake, definitely not. it's the same as AEM's intake i believe, jsut rebadged TRD. exhaust wont net you anything noticeable until you get a full exhaust system. TRD shocks and springs combo are worth it. rear sway bar i cant say because i dont have one but many people say it's the way to go for those that dont want a more aggressive setup in the hotchkis bars. front strut bar, eh, take your pick of the ones out there.

 

I don't think it's really the supercharger that has problems... but when you start adding stuff to it, like the pulley or headers - that's when the problems come in with leaking seals and stuff. I don't recall reading too many issues about unmodded ones. But then, where's the real fun I guess... right?

 

This is all very early sort of brainstorming. And I won't be doing any of this until maybe 4-5 years down the road.

I'd like to be making around 200-210hp, around that # for tq. I know that the TRD s/c gives those kind of numbers (hp at least), so I'm considering that. But I'd like to consider just using a nitrous kit and making similar (and less, if more reliable) power, and that would keep my fuel economy at the same when I don't need the extra power 24/7. Besides, it's more affordable as far as I know. I do need to do more research into it, and find more information on the issue of reliability as well as recommended mods and price.

What I'd like to avoid is getting a turbo, because those are even more expensive than the other kits AND I hear that they require much more maintenance than the other kits. Issues like clean, good oil. And the # and $ of mods that are almost necessary for a good, stable t/c'ed vehicle means even more $$$!

So, right now it's between the nitrous and s/c, for me. Again, in the long run (4-5 years).

PS - technically, wouldn't the nitrous be 'forced induction', too? It is adding more oxygen into the fuel, right?

 

my s/c was stock when it started leaking oil. got the replacement and said screw it, now i know it's not mods that cause the leak

why not get both the s/c and nitrous? my bottle should arrive on friday ;).

 

I don't want to go that far overboard! I'd like to keep it practical, that's why I'm only aiming for 200-210 horses.

 

i'd say get the s/c then. you'll eventually spend more on the NOS with the refills. the s/c doesnt need to be refilled

 

I really don't think I'd use it that much, but I don't know. I may change in 4/5 years.

 

There's no real advantage going with only TRD stuff. Your warranty is voided either way

 

im looking into an exhaust for myself also....and i dont think that the intakes wont work with a s/c(without throwing the c.e.l.) but i can tell you that i made 206whp w/ trd s/c (stock boost= 7psi) on a manual '07
