Weapon R header

[Mando]

Im thinking about gettin the wepon r header w/ s-pipe for my tc and im really stoaked about it. The header gives 25 whp when put w/ intake and a catback exhaust. I know its not "Street Legal" but its a nice boost in hp. Now here is my problem i wanna know how loud will this be because thats a lot of hp for headers and i dont want to just be crusing at like 45mph and a cop pull me ova for noise pollution. Don`t get me wrong i like the loudness but my fear is it being so lud its sounding like im riding w. open header.Anyone know how loud this monsters gonna be?

[JoshCrane1]

NO LOUDER than hondas with shit mufflers at high rpm, and when cold.

[Mando]

So its not gonna be too loud?

[Krdshrk]

It will be pretty loud compared to stock. You'll get used to it, though.

[zanson]

IHE, (intake headers and exhaust) dont get you much if any HP gains... MAYBE 10 hp at like 5K RPM.... Maybe...

just sounds different and louder.

[Krdshrk]

Yeah - don't go by Weapon-R's numbers. Actual dyno numbers say about 12 WHP from headers. With Full Exhaust and Intake you're probably at +20 HP.

[JDub86]

Also if you have the TRD Exhaust it will probably be really raspy.

[JustAtC]

from what i've heard with several cars is that replacing oem header with an aftermarket header is going to lead to a very raspy sound. because you are removing the cat. it can be compensated a little by adding resonators though. just my $0.02.

[hotwheelsrs1]

yeah, theres no way a header is going to give u 25whp on a car that is stock with only 120-125whp, id say mabe 8-10 if ur lucky, and its gonna be really loud with the IHE combo, i would suggest a few resonators and a good silencer also. but for the record, i want to get the header also lol:rofl2:

[peety tC]

i would say DONT listen to all these fools unless they actualy have the IHE set up. Because i have the injen CAI, MMW ( weapon R ) 4-2-1, and the GReddy EVO II, and yes it is very raspy and loud, but if you have this set up you WILL notice a difference, and you will be faster. To prove my point, my friend has a 5sp tC with the TRD. So we raced..... got ahead of him from the start and the gap only got bigger. We only got up to about 55-60, but beilieve when i say it will give you hp, not a tone but enough to feel it.

i wasn't saying anything about hp numbers. i was just letting him know he's gonna be getting some rasp with any IHE setup he goes with. so quit flexing your e-muscle, because we are just providing our opinions on the matter.

[_Keith_]

The 20+whp is PEAK GAIN GUYS! You guys should know that....

[zanson]

-_- and this is why i usually stay out of these conversations. b/c people always get jumpy about it all...

[xX EL HeFFe Xx]

I have an IHE set up and plenty of extra HP compared to stock, the Weapon-R header IMO is the best one you can buy due to the fact of having the S-pipe already with it!!! I have very little rasp but i also have an 18 inch resenator...youll be happy with your purchase...my $0.02

[hotwheelsrs1]

^ yup thats y i never post in this area, and peety, no kidding u feel a diference from a header, axle back and intake, u better feel a diff. considering u droped about 800 to a grand for all that, and it doesnt hurt that u mentaliy think ur car will be "faster" so in turn it feels faster. and racing a buddy on the street doesnt mean anything for the performance gains on ur parts, cause no two drivers are equal, o and dude, ur sign is SICK, but... did u know ur tc is not JDM?:oopsp:lol

[xX EL HeFFe Xx]

1. megan header 145
2. HKS Hi-Power 200+100 (piping and resenator)
3. Injen CAI 0 (gf payed for)
--------------------
only payed 445, not 800!!!

[Krzd1]

Get the WR header. It's a true race header with the "S" pipe included.... Plus WR is a Scikotic supporter :)

[Krdshrk]

Just go turbo :D

[Firestorm]

Just go turbo :D

+1


and....


lmfao @ 25whp.

We took a stock 05 tc dynoed it at 139hp and 144tq.

Injen CAI, MMW, S-Pipe, Full Exhaust = 19.8hp gain.

1500+ or more is to much for N/A parts.

TURBO FTMFW!!!
I found a site to get a Greddy Turbo + Emanage Ultimate, 440cc injectors for 3750 Shipped...

[fightinsk8ers]

im gonna get all this stuff then go turbo!

[JoshCrane1]

and waste your money go ahead, but to be nice, ill tell you, when you go turbo you will be replacing that header, and also that intake. so if your going turbo, save your money and just do s-pipe back.

[fightinsk8ers]

why must you replace the header and intake sorry i dont really know that much about turbos and have been reading up on them all i can...thanks for letting me knowi appreciate it

[JoshCrane1]

theory wise, turbo's spool up and create boost by exhaust flow. to do that the turbo must be in the exhaust flow,(in your header),called a turbo manifold, then be routed to your throttle body,(or through a intercooler first),thus modifying your stock intake piping.

[JoshCrane1]

without being too technical.

[fightinsk8ers]

lol that was a lil to technical for me but i kinda get it so the turbo mani replace the headers? idk im lost haha help me

[JoshCrane1]

lol that was a lil to technical for me but i kinda get it so the turbo mani replace the headers? idk im lost haha help me
yes, the turbo manifold replaces your header, and instead of your intake pipe going from your filter to your throttle body, the pipe goes from your filter to your turbo then to your throttle body,(unless you have a intercooler, then it goes out your turbo through your intercooler, then into throttle body.

[JoshCrane1]

a turbo is basically an air compressor, which is spun by your exhaust.

[Firestorm]

The Turbo Kit replaces, your Intake pipe which runs to the throttle body, and the Headers, with an exhaust manifold which the turbo is connected to and the down pipe.

The down pipe is what connest to your S=Pipe like a header would same 2 bolts.

Instead of sucking air in threw the filter into your throttle body. The turbo spins off your exhaust coming threw the Exhaust manifold which is basically your new "header. The turbo then blow air through and intercooler.

The intercooler cools the hott air before reaching your throttle body..

Thats why turbo's add more power.

The more air you rush to the throttle body the more power you will make. But you have to upgrade the fuel injectors to cover for the amount of Air. That's when tuning comes to play.

Your intake pipe now filters the turbo. It connects to the Spool housing so crap doesn't get sucked in it.

If your running an Open Wastegate like I am, some of the exhaust will "dump" out of it. 90% of it will still run threw your exhaust system.

Also if you ever turbo you should extremely upgrade the stock scion piping b/c it kills turbo life and chokes it.

There i tried to simplify it for you...

[JoshCrane1]

in more simple terms, your intake and headers will be replaced with a turbo kit, if you wanna learn more on how it works, there are plenty of other threads to explain in detail.:shock:

[fightinsk8ers]

thanks guys

[kris5597]

hey sup guys. im about to install a weapon r secret weapon intake on my tc and i wanted to know how much whp i will expect to gain from it. and also i wanted to know if anyone could tell me how much hp i can get from an axel back kit and a cat back kit. made by tsudo or just average it dont matter

[JoshCrane1]

INTAKE will give you <10whp, more noise than power increase. and axle back will give you bout same, cat back though put you about<15whp. intake and catback will put you bout 20whp peak increase. but seen dyno results of Intake,header, and catback being right at 20whp, so my numbers might be a tad high, good luck.

[Krdshrk]

You're not gonna gain much. short ram intake + axelback = MAYBE 4-5 WHP.

fightinsk8ers - here's a pic to make it a lot easier to imagine:
http://i3.photobucket.com/albums/y82/krdshrk/Car/IMG_5007.jpg

You see the turbo exhaust manifold takes the place of the headers - it channels the exhaust into the turbo manifold, where it spins the compressor. The compressor takes in air from the intake (you can see it's not going back to the throttle body like normal intakes do - it goes to the turbo itself), compresses it, then through a series of pipes (Through the intercooler) it goes back to the throttle body.

[kris5597]

are u sure thats all i get is 5 with axel back and weapon r? cause i was reading and the weapon r gives me at least 10 whp. now ive heard that the axel back is just sounds not power but if i combined it with a midpipe it would give me about 10whp? is that true?

[Lunchbox]

Nick.... I'm going to steal your turbo kit.... don't leave your car alone...... :shock:

[Krdshrk]

Weapon-R says 10hp, but they don't also tell you that that's with full exhaust, headers, etc.

I go with true owner's dyno tests.

[kris5597]

o ok well that sucks. then how in the hell am i supposed to at least get to 200 whp without turbo? so ur saying with headers, full exhaust, and weapon r, that im only getting 10 whp? that sucks ass.

[maloy]

o ok well that sucks. then how in the hell am i supposed to at least get to 200 whp without turbo? so ur saying with headers, full exhaust, and weapon r, that im only getting 10 whp? that sucks ass.
thats gonna be tough but doable ur better of saving either for sc or tc in the long run makes things easier for you.

[kris5597]

alright kool. what do yall suggest tc or sc? sc will keep my warranty tc wont so ill prob go with sc. plus no turbo lag with that anyways

[Krdshrk]

There's no real way to hit 200WHP with just bolt-ons without investing serious money. The motor's just not built that way. People have tried it - it just plain doesn't work.

Intake/Header/Full exhaust (S-Pipe, Midpipe, Axelback), pulleys, etc, will net you maybe 30 WHP. Stock manual tC dynos at 145 WHP so at most you'll be in the 175-180WHP range.

Turbo lag's negligible in my car. I spool up to full boost at 3500 RPM which comes fast. Superchargers don't hit peak boost until they're up around 6000 RPM.

Or.... you could go with Nitrous :p

[fightinsk8ers]

Thanks Nick i really appreciate it...tahts why this group is so awesome becuase people will take the time to teach you unlike some other websites....so anyways yeah im not gonna be putting on any of these bolt ons the only one i will probably do is the pulley but other than that im gonna save all my money and go TURBO, ive realized there is no way to get the kinda power that i want from simple bolt ons and its pretty much a waste of money if you wanna go big. Thanks again


craig

[kris5597]

alright ill go with the supercharger and get the good bairings and the work but what a bpv and where can i get one and where can i get the pulley thing u were talkin about. sorry dont feel like going back and looking i gotta headache and reading aint helping but hey somebody call me and talk to me about it that knows what they are talking about i would really appreciate it. just when u get a sec. my name is Kris and its 225-907-3514 it will be easier to understand over the phone than reading a bunch of forums but yall would be the shit if yall would call me and let me know what i should do cause im clueless so many parts so many dif ways i just wana hear about them. basically to sum it up i want my tc pushing 200+ with torque and horse nearing 250 thats what i want so if any ideas drop me a line laters

[kris5597]

well how much horsepower on average will putting on a weapon r secret weapon intake, invidia s pipe, tsudo catback, lightweight pulley, and ignition equalizer. how much horsepower do u think i would get from all that combined. then i will state the point im getting at just reply with what u think.

[xX EL HeFFe Xx]

probably 20-25

[Krdshrk]

Don't waste your money on the ignition equalizer - it's pure bs.

With the Intake, S-pipe & catback, you'll probably add about 10-12 WHP. Pulley will add a couple. 15hp max.

[kris5597]

is it really ok i wont. ok how much stock is a scion tc. hp/tq 161/163 right. you add 20-25 hp and u get what 185 or so. i was reading at a scion website, not sure which one but they had an 05 tc with an ingen short ram and a injen exhaust and their car was pushing 185 hp with just that

[kris5597]

why does each part that i look at say that it will give me an increase of a certain amount of horsepower. i mean i talk to a lot of ppl about performance parts and shit and everybody says a dif thing so im stuck smack dab in the middle and dont know what to believe. so im prob going to just have to get all the things i think will give it more horsepower and put them on then compare it to stock. and see how much each thing says its supposed to give and add that up which should be 200+ according to each part. then ima take it and dyno it and see what that says then i will just go with that. and deal with it and then i will know who to believe. i want s pipe back exhaust i wana keep stock headers for rasp purposes and warranty if ya know what i mean. and why is the ignition equalizer such bs. u know anyone who has it that can tell u it was a waste of money? cause i think ima still buy it regardless just for my own personal experience. ima put a secret weapon intake on with a cold air box for it. then a lightweight pulley, and iridium plugs, which wonht make a dif ill just know i got em. then i will just go with that because thats what i want. if its not enough then ur advice for sc will be taken and i will purchase one when they are cheaper. but thats what i think.

[_Keith_]

Get a base dyno of the car stock

add the parts you want then dyno again

[Krdshrk]

tC is 160 HP... AT THE CRANK. At the wheels, the car will dyno about 145 WHP (Manual), 130 WHP (Auto).

Bolt ons will never add on power linearly. With a cold air intake, you actually LOSE some power on the low rpm side because it takes longer for the air to travel into the intake manifold. You do make higher PEAK power, and for some reason that's what everyone thinks you make ALL THE TIME. It's just not true. The best CAI (Injen) makes 8 WHP. The best header (header only, no s-pipe) makes 12 WHP. However - the power is not linear and doesn't just "add up". You can't count the intake/header as 20 WHP because the power is made at different points. The only true way to tell how much you will gain is to dyno it, bone stock, then add on all of the parts, then dyno again, like Keith said.

Also - do you know what the "ignition equalizer" is? It's a larger ground kit. This is NOT a honduh with a weak grounding. The ONLY way this would be able to help you is if you have a sound system that has a huge power draw.

Trust me - I've been a tC owner for 2 years and have seen what people have gone through.

[kris5597]

sweet alright thanks. yea ill prob dyno as soon as i get the chance then put on my shit on and dyno it again. i understand what ur talking about. and yes i knew that about the cold air. takes to long for air to get up a longer route. only true way to get the power that anyone wants it sc or tc. and which is why thats what ima do... eventually when they mark down the 07 sc cause that shit aint worth it. but yea ill just get everything i planned except the ignition equalizer and be happy with it for that. but u think i will feel a pretty good dif from stock to secret weapon intake, lightweight pulley, s pipe back exhaust, and a torque damper??? to send more of that juice to the wheels?

[Krdshrk]

You'll feel a slight difference. Short ram intakes help a little with power. Not as much as a CAI but you don't lose the low-end power. S-pipe and full exhaust will help too. However, the part that is the most restrictive is the Header. Because there's a catalytic converter in the stock header, that's where the most power is lost. The 2nd cat is in the exhaust midpipe. If you get a full exhaust, try to get one with a high-flow cat.

[kris5597]

ok thanks ill look into it

[satyr1ne]

damn this thread has some great info on turbos and such. i really wish i would have went turbo a long time ago.damn like i said great info!!

[kris5597]

yea ive learned a lot just by talking to these guys they really know what they are talking about.

[Krdshrk]

You pick up a lot of stuff when you own the car and have been working on it for 2 years :)

[kris5597]

well yea i can def see that one. i mean i looked aroound for a long time before i decided to go with the weapon r secret weapon. it looks promising. it has more air flow than a conventional air intake and so does the sw filter. its supposed to produce more power than a short ram because of its design and 3x as much as a stock intake. but produce just as much power as a cold air without the loss at low rpms but we will see it comes in tom ill let u know what i think.

I think you need to read up about different dyno's and how they read different

[kris5597]

ok. why. it said hp and tq. and it was like an 8 hp dif between stock and intake.
