I have the Tc's Sc'd and at first I was pretty impressed with the feel of everything, power, delivery time, just the whole thing in general. Then I took it to the shop and added a handful of goodies, man it feels like a whole different car. I went with the Megan racing headers with the 2.5 inch t-304 magna flow exhaust... little to no rasp. I the added the 2.5 inch custom compacts s-pipe, I upgraded the Bosch BPV to the 110 sport and then built a custom cold air box. I will be going for the dyno in about two weeks but I'de bet atleast 230-240 whp. It hits hard even at 2,900 rpm's now. I love the feel and the only thing I have left to add is a FMIC. On 7psi, my car will keep it's warrenty and be around 280-290 to the crank. Oh yeah some nice 225/45 Bridgestone Re-750's for traction in the summer, and a limited slip.

To put it simple just like everything else the S/C is just a large peice of the puzzle. But if you can put the rest of it together correctly and be happy pushing 240-250 whp then you can do it under warrenty. I have had a few races with my car like this and I beat an RSX-S, S/C'D Tc and I decently modified spec V, all by atleast a car length or more from light to light. Not bragging simply saying that the S/C T/c if you free up the horses trapped in there can push some numbers. Also I found a great deal on my Magna flow exhaust pm me for questions if you are interested.

Oh for anyone screaming about the SI's they run 7.3 0-60 stock and out the door pricing starts around $21,000. Thats a supercharged or turbocharged Tc. Doesn't add up, but some are Honda loyal.

Personally i would have gone Turbo. Especially since you're in Kentucky...But congrats on the SC.

Nic gains. I am deffinetly going the same route. As much power with out hurting reliability and warranty. I have an HKS exhaust and the S/C. I want a header to s pipe but i dont want the rasp and CEL. And of course when someone has an intake it will be my first thing to throw on it. Let us know the dyno gains of your setup.

Nice job man :) Keep us updated with your dyno results.

Very nice enjoy your new goodies, just make sure you consider the SC pulley (not crank). It has been shown to increase output by 20hp 19tq. I will soon mod my RSX -S k Pro and a few other mods should be at 220whp N/a on a 2700 pound car. Hopefully i can SC my TC if they ever design a proper auto kit for it.

Nice Job. Don't forget to post up with the gains after you've dyno'd.

Congrats on the TRD s/c

Nice, but where are the pics?

sounds nice. but yeah i'm wanting some pics.

It'll be a little bit before I get some pics simply due to the fact that I don't ahave a digital camera nor do I have a scanner. I'll see what I can do. The dyno's are what I am interested in more than anything. I am really tempted to boost the PSI but there goes the lovley warranty.

think about swapping the spipe and switching catback -- thats gonn a give you a few extra hp right there.

I am a noob so I prolly have no idea what iam talking about but you mention reliability, if something breaks wont the warranty not be in use since you changed the supercharger? and I thought increasing boost on turbo or sc running up to 280 whp stresses your engine all the same weather turbo or sc?

If it's been said once, it's been said UMPteenth number of times....The Umitiza Intake works with the S/C...

I dont want something that just works. To many people go and add parts because they work. I want something designed for the s/c. It will be like adding high compression pistons just because it works.

I want something designed and tested to work with the s/c. I am in this for reliability and fun, not just to throw something togethor so that i have it.

Since when would new headers not void your warranty (granted you don't take it off before going to the dealership)? Exhaust I could see, or even the custom cold air box, but not the headers.

well not "void" your warranty but they most likely will refuse to fix something with your engine if its broken saying that a header caused it

well not "void" your warranty but they most likely will refuse to fix something with your engine if its broken saying that a header caused it

First they have to prove that the header caused it, they can't refuse, because "they think the header did it". You can slap anything on your car and it won't void your warrany just for putting it on, if somethig breaks and they determine that it was caused by an aftermarket part, then they can refuse to fix the problem under warranty, but they have to prove it on paper, not just with words.

huh, never thought that tC could be pushing about 280-290 at crank with just header and s/c, but it sure sounds sweet b/c I always thought that tC would just stay in a lower class compared to others (350z, S2K, etc) ANywayz, keep us updated.

An Intake is an Intake in my book. Unless it's dyno proven of course.

thats the whole point - when they come out w/ the s/c intakes they are going to be dyno proven..... the same way all the other parts are. Scion people go by what looks good, what sounds good, and what performs. This car is too hot to not be picky ...cause the next company that is putting out a better product is getting the sales.

How can you cater an intake to the S/C. i don't see how an intake on a S/C car is going to be any different than the same intake on the N/A version. Besides putting out more power DUE to the S/C.

certain pipe sizes and designs could just possibly be the difference of 2 horse power and a few foot pounds. Thats why design counts... just ask zpi, they are spending a nice amount of time on an intake and stuff like that for the supercharger.

^ exactly

man that sc is looking pretty good especially for someone like me who wants to learn how to tune everything myself sc is a lot easier then a turbo and same hp is possible, hey were you thinking of upping your boost a little with the pulleys, that and the fmic sound like it would put you in the very good hp range

man that sc is looking pretty good especially for someone like me who wants to learn how to tune everything myself sc is a lot easier then a turbo and same hp is possible,



You forgot to mention with the addition of a few more thousand dollars, the same hp is possible.

How about a timeslip?

Haha thats true, but a sc seems easier to tune for me ( I never tuned anything, just small stuff, cai, oilchanges, install subs and amps, but never f/i ) turbo is more complex i think id end up blowing my engine

plus everyone is saying turbos are cheaper turbo kits are all in the 4500-5000 range, exept for zpi stage 0 but no intercooler no fuel managment thats just as bad as the sc and cost only a little bit less. I do like the fact that its easy to install sinc ei plan on installing w/e i get myself

Why does everyone leave out the fact that it's OPTIONAL.... :doh: Stage 0 with added IC and E-manage still comes out cheaper when comparing $ per HP.

sure - if you dont want a boost in hp throughout the entire band, get a turbo.

That's incorrect. The turbos make more boost early on than the TRD sc. ZPI's kits make boost around 2k RPM whilst the sc requires revving to about 5k rpm to get full boost.

Its too bad that TRD isnt making a turbo that will make your warranty happy.... :tap:
or maybe toyota making it so we can put a ZPI turbo on and not void a warranty :tap:

i was big into turbos but not anymore --- the more im reading about superchargers in general ....the more im liking them. its a personal thing --- next year the supercharger is going to happen for me.

Yeah I'm leaning towards the SC too, but some of the numbers that I have heard off of that stage 1.... whoa.

ive talked to too many people - you get up into the 300whp range ... you need different pistons and it wouldnt hurt to get diff rods.... like i said.... nobody has to respond to this statement but that is my view on the matter. I think this engine was rated at around 260whp w/o internal work. Higher then that i think internals is a must. The supercharger can put out more boost that what you ever will put into your tc. Its running 6.5psi and is able to be turned up to 19psi if the setup could handle it.

Yeah see I spent quite a lot of time reading about superchargers and turbos and their difference and pros and cons and in the end i came back to what is in every comparing situation sounds logical: Nither is better, each has pros and cons.

Here is what I got out of the articles summarized(iam going to compare trd sc therefor a lot of pros of sc wont apply to it, because it is cenrifugal) - Turbo - ZPI0 - turbos create more boost meaning more power meaning if you want a pure race machine turbo would prolly suite you more, just as an example the sc can spool to 40,000 rpms which is a lot higher then other sc however compared to a turbo 150,000 this is nothing.. However turbos are harder to install, harder to maintaine( you have to wait for them to cool down before turning of your engine and you gota check on your oil a little more often), and generaly are a little less reliable then a sc compared to the centrifugal sc not by a lot. Supercharger TRD - this is a bit tricky since a lot of normal sc stuff doesnt apply here because trd uses a centrifusial sc which is more of a turbo driven by a belt instead of exhaust (compared to totaly diff design with 2 other sc) the sc is a simpler, it is virtualy maintance free(no oil checks and waiting for it to cool off) saying that sc give you low end power doesnt apply here since likea turbo you have to wait for the sc to spool up to give any significant boost. oh and you can keep your header with the sc where as in a turbo will replace it with a turbo manifold (and be trickier to install to a custom spipe) the zpi 0 also is not much harder to install then the trd sc most other turbos kits will get complex though compared to the sc.

So its a choice between simpler and less maintance (good for newbie tuners like me) and a tiny bit more reliabilty over getting more horses but doing some extra work for them (dont get me wrong this kit isnt much harder to install then the sc just harder to upgrade). Now people will say but the sc can be moded up to the same hp as the turbo yeah true but you are also sheeling out more money for it so comparatively speaking the two differences will always stand. Both setups can yield 300 whp gains I believe.

Yeah I'm leaning towards the SC too, but some of the numbers that I have heard off of that stage 1.... whoa.

As much as 400hp has been achieved on stock internals with the TC. Not recommending it, just stating a fact.

I thought 520 was achieved until something blew. I meant both system can achieve 300 whp with mods to the turbo/sc and perhaps forged pistons for safety.

im not saying that 300whp is possible with the stock setup but I have talked to too many people and "I"wouldnt do it to my car.

with forged pistons and valves why not? stock i wouldnt either but froged internals why not?

with forged pistons and valves why not? stock i wouldnt either but froged internals why not?

im saying what you are saying. I think that with forged you are good ...but stock I wouldnt go crazy w/ thehp.

oh yeah i dont think for a daily driver that wants to maintaine realiability and races weekend to go above 7 psi or about 250-260 hp ones you get to 300 or above 8 psi you gota start investing into forged internals.

260 is good enough for me for a daily driver. But 300 hp would be nice too.

Yesterday I headed up to Louisville to hang out up at ZPI w/ Kenny. Man they know their stuff up their and they have a real nice garage and cars in it. Id'e say total they had 6 tc's up there. Anywase I decided to add the zpi supercharger pulley and I go in for my dyno Tuesday. Pretty much I've done everything to the supercharger set up other than an e-manage. I am excited to fin out what kind of numbers it is showing. The whole staff up at ZPI is great I highly recomend. Any garage that let's there customers sit in there with them and watch the mechanics do everything is a reputible company that has nothing to hide.

Hey cant wait for you to post up the dyno wondering how mkuch power you are running anything above 230 whp will arleady be good in my book. Btw def agree with them letting you watch what they are doing. Other places always give me crap saying how insureance and so on and you cant even watch from the outside which i think is rediculois. Needless to say I stay away from places that have a problem letting you watch from the outside, and try to do as much work myself.

yup - post up the results when you get them. ZPI seems to be a quality company as they interact w/ the public. Other places need to take notes on this. I know i asked this last week and got a reply but any new news about the supercharger intake ....lemmie know. Im checking back daily because im interested in knowing how the intake is performing w/ the supercharger. I wish zpi was close to where im at cause i would take the trip and pick some of their minds.

Yes an intake would be nice. Since the whole point of me getting the sc, is that I can do small upgrades first aqnd then keep them with the sc hehe.

dyno please?

SALLAD where the beef? (dyno)

SALLAD should have a dyno next week. I think we are going to try for wed or thurs. He has been waiting for me to set it up with our dyno guy and I've been waiting for my dyno guy to get back in town. He is due back in monday so hopfully we will get it worked in next week.

I planning on taking one of our 5 speed tCs and use it for a base line hp and tq #'s.

I promise SALLAD or I will keep you up to date.

come on i want to see the dyno numbers! lol i'm planning to have the same setup as you but im waiting on an aftermarket emanage that works and can be tuned until i fully commit to getting the s/c.

I'm looking foward to seeing the #'s myself.

His car is strong. He has been nice enought to let me drive it a few times, I can safely say it noticably quicker than a stock s/c tC.

His real problem now is traction, but he is working on that also.

7.3 stock? thats terrible. My tiburon cost me 16,800 OTD and ran 15.2's with a 150$ intake (automatic!, 7.2 0-60 iirc) >_>

I have the Tc's Sc'd and at first I was pretty impressed with the feel of everything, power, delivery time, just the whole thing in general. Then I took it to the shop and added a handful of goodies, man it feels like a whole different car. I went with the Megan racing headers with the 2.5 inch t-304 magna flow exhaust... little to no rasp. I the added the 2.5 inch custom compacts s-pipe, I upgraded the Bosch BPV to the 110 sport and then built a custom cold air box. I will be going for the dyno in about two weeks but I'de bet atleast 230-240 whp. It hits hard even at 2,900 rpm's now. I love the feel and the only thing I have left to add is a FMIC. On 7psi, my car will keep it's warrenty and be around 280-290 to the crank. Oh yeah some nice 225/45 Bridgestone Re-750's for traction in the summer, and a limited slip.

To put it simple just like everything else the S/C is just a large peice of the puzzle. But if you can put the rest of it together correctly and be happy pushing 240-250 whp then you can do it under warrenty. I have had a few races with my car like this and I beat an RSX-S, S/C'D Tc and I decently modified spec V, all by atleast a car length or more from light to light. Not bragging simply saying that the S/C T/c if you free up the horses trapped in there can push some numbers. Also I found a great deal on my Magna flow exhaust pm me for questions if you are interested.

Oh for anyone screaming about the SI's they run 7.3 0-60 stock and out the door pricing starts around $21,000. Thats a supercharged or turbocharged Tc. Doesn't add up, but some are Honda loyal.

waiting for the numbers man.

sounds like a great setup. just cant wait to see the numbers

Myself and scion_south... Jonathan the Scion manager at Toyota South should be going up there thi supcomming wek early. Sorry it has taken so long. I am going to get it tunned also next week.

You should definately crush my numbers man... Cant wait to see it.

Ok we dyno'd my car today. We took a stock Tc up there at the same time. We are going to allow ZPI to host everything so It should be up soon. Thanks for the patience guys. The dyno was done on a Dynamics Dynamometer.

Oh yeah we also did all the air fuel numbers for everyone to show the numbers and what the ECU reflash does. Also what the ZPI pulley does and whetehr or not it could cause any damage to the supercharger or engine.... oooo the suspense

watchin this like white folks watch FRIENDS

Thats just wrong.. lol.. such suspense.

watchin this like white folks watch FRIENDS

or american idol..... :clap:

c'mon you guys are such teases. Post the results already :pray: :pray:

where are the numbers at already?

Just kind of glancing through this thread, I haven't seen anyone state that this power still has to make it to the ground to be useful. Unless you are doing it for burnout contests or something. I don't see the point of having a 300+hp FWD car. Drag racing maybe but that gets boring.

well, we're all hoping lsd comes out to help us out too.

I'm running almost the exact same setup, same parts just different people. The power gets to the ground, just don't count on it getting there in second gear.

With an lsd this car will definetly be a beast

headers void warranty usually

not at our dealer :lalala:

(we're in the same town btw)

So whatever happened to the dyno results?

nov 26 this thread started, and we would have numbers in two weeks. Jan 12 it was finally dynoed.

I have nor problems with people not wanting others to know their numbers or setups. But why start a thread, promise a dyno, take forever to get one. Then not post the results.

3 keys on the keyboard will make alot of people happy and answer alot of questions as, what to do next.
Maybe i am in a bad mood at work, but come on....post the numbers already

Sallad posted his numbers here: http://www.scionlife.com/forums/viewtopic.php?t=104908&highlight=

yeah I am sorry about that. I thought my dealer had posted the numbvers a while ago and never really bothered to check to see if he did. I ended up posting them on another post just as a reference. I am sorry guys
