Hey guys they have the new Dyno numbers out from their reworked header ... check it out im guessing its an Automatic.. Not bad though


http://www.tctunerz.com/content/view/102/2/

8-9 hp not bad for whp. anyone have a price? I was going to try to wait for the weapon R header, it looks really nice and performs well

Well their previous header was selling for 299 i believe. I just wonder why TC Tunerz dosent provide additional information on the Dyno run. Things like tranny type exhaust configuration and so on.

If those numbers are just with stock exhaust and intake imagine the difference with intake and full exhaust..

Their base numbers are still way low compared to what everyone else is getting.

thats what worring me!

It says it has a built in catalyst. I wonder if this header has a carb number so it won't void the emissions warranty.

The car is automatic. Thats why the torque is so low. Its all stock also. The hp isnt really that low for an automatic. Some 5speed tC's are putting down those numbers. Before they dynoed with an open intake box (no filter) and the header. They posted about it.
I want to know what this header sounds like with the TRD exhaust!!!!!

The header is now $264, but I dont know if its the new header.

Hmm, for a header with a cat in it (assuming that it will be legal becuase of that,) that's actually a decent performance bump. Would definitely be interested in seeing some numbers with an intake and exhaust added to the mix.

^^^^^^ Definitely......

I've seen dynos for other autos that are still way higher than their numbers. Shouldn't drivetrain loss be consistent for both torque and hp? They're showing a 19% loss in HP (perfectly feasible) but a 25% loss in torque which doesn't make much sense to me.

Im curious where have you seen other Dynos for Auto TCs havent found any except TCTUNERZ.

Other boards.....I'll have to search them out again.

it might also be there dyno you'll hardly ever get the same #'s on diffrent dynos

Id say those are great numbers for an automatic. The torque does seema bit low.....

Those gains are great for a carb legal header. Well Im sure the header needs some test. Ohh, if some of you are wondering the header is made by Megan Racing.

i heard of that company before (Megan Racing)

I have one of thier mufflers on my Mx6. I have to say great quality.

I got an auto im really concidering that header but in about 3 months, for now let them R&D it some more. Megan is a good company as far as exhaust im getting the injen axleback its a straight through design sounds good and with a removed resonator and second cat i think it will offer good gains even with the stock pipe. Now if only some company released a good intake with reasonable unequivocal gains 10hp 10ftlbs or more. That would be sweet. :D

Do not put a full intake on an automatic tC. I had the K&N on my moms car and when removing that black box on the intake tube it removes low end power. Thats something you dont want to take away from an automatic.

I put the stock airbox back on my moms car and my god the difference is night and day. Although the car did pull hard up top with the intake I just cant sacrafice that low end power. Thats what gets the autos moving.

Lol i know ray ive been following your posts. It seems you do lose torque with all the current intakes but im sure eventually one will be made where there will be gain through out the powerband. All the inatkes for this vehicle you gain up top lose down low. I am getting exhaust for sure its just hard deciding right now with the lack of real quality catbacks. I wish we had a V2 with the kind of gains thet can be acquired on the civic SI 18 hp and 17 tq with nothing but intake thats really nice. :shock:

hey ray i got a K&N drop in filter for my2003 corolla that i superchraged. Do you think it will provide any gains or torque loss.

If you keep that stock plastic box (in the middle of intake pipe) the low end power will always be there. A drop in filter wouldnt lose any power at all. Some gains my be felt???

I dont think theres going to be an intake that will keep the low end power. All there going to do is dyno the car from 3000rpms and up. Thats what I dont really like about the TCTunerz dynos. They start from 3000rpms and go up. I want to know what the curves look like under 3000rpms.

it might also be there dyno you'll hardly ever get the same #'s on diffrent dynos

lol very true at one point one of their Dynos showed 130hp and 113 tq for and auto..lol really off, then another showed 130 hp 141tq for an auto TC, lol hmm big differences. Now they are sticking to one dyno. I emailed them and they posted more info on their project tc like tranny type and so on. The auto #s are 130 hp and 123tq to 140 tq.. wierd. :roll:

Don't know if anyone else noticed this -

in the article, they say "The Performance header installed dyno.. 138.9hp / 129.8tq"

But if you look at the dyno graph, it says "MAX TORQUE = 138.9 MAX POWER = 129.8" So it looks like it lost a little bit of whp but gained a lot of torque

The stock dyno chart says Max torque=130 and Max power=123. However above the dyno chart they listed the numbers backwards stating it had max power of 130 and max torque of 123.

So in reality it gained almost 7hp and 9 torque.

"Hmm, for a header with a cat in it (assuming that it will be legal becuase of that,) that's actually a decent performance bump."

It is against EPA and CARB rules to remove or replace a factory installed catalytic converter while the vehicle still has a factory exhaust warranty. If the original factory cat needs to be replaced due to damage or failure, it must be replaced with an OEM part.

Of course, if the aftermarket part in question passes the CARB certification process and is issued an EO Number from CARB, then you can legally install the part. Just because it has a cat does not make it street legal. Keep this in mind.

I agree!

Is there a pic of the honeycomb converter on the cat with this header set-up, because it still looks like a resinator to me.

Interesting, thanks for pointing that out. One more question though, do the CARB rules apply for states other than California? I know they're super strict on emissions, but I live on the other side of the country :P

Megan is a really good company.

Ill take any japanese performance parts over america. They are more reliable, trusted, and make great quality. they are also more expensive too.

too bad there isnt any japanese performance parts available now for the tC. (if there is post it here please)


as for the tctunerz new header, im pretty sure its not gonna out perform the DC header. with that converter in the way its not gonna be as loud without it.


Ima wait 2 weeks and see if anything new and improvement is going on. if theres nothing, ill take the tctunerz header. i hate that CEL light.

have to login to view article? oh forget it...
