Hey everyone! A number of you have been asking me about what gains I had with a header and my filter so here is a video. 174WHP from 155WHP. TQ is now 138 LB-FT. Enjoy the turbo-like sound of hissing flex pipe and whistling intake pipe !

Feel free to ask questions.

TSX2345

Where did you go dyno at?

valeratj

Midnight performance, Rancho Cordova, CA

bc811

nice dude~ where did u get this header? And is it the most powerful (or most hp gain) header out there for a tsx?

vidgamer

I noticed a while ago that headers seem to be the best bang-for-the-buck mod.

(Too bad there are so many issues with flex pipes, rattles, etc.)

EuroRuben97

did you reflash too or is that just with the header and what not

valeratj

Only the header and K&N drop in filter. I am waiting for 05 AT reflash to come out

valeratj

THE most powerful headers are race headers which delete catalytic converter EX: Weapon R race header, TODA. The problem is that they are absolutely illegal in California, for street use. Topspeed header is for sale on Ebay from a user called tjbutique. I bought mine for $175. It is a replica of DC sports header but instead of being ceramic, mine is stainless steel. The hissing flex pipe is an issue but even if I was to replace it, it would still cost me less than $500 DC Sport header or $700+ Comptech header which rattles. Personally I would recoment this header for its unbeatable value Another person before me bought one of these and put it on a completely stock car. That gave him 14WHP. If u are planning on a CAI and reflash, I would definitely suggest getting aheader. As vidgamer has already pointed out, header = bang per buck.

TSX2345

The most powerful header would be the HyTech along with rest of HyTech exhaust system. HyTech =

carcrazyboy68

can someone guide me to a link for the topspeed headers on ebay. i cant find them

valeratj

is it because u are selling it ? lol

carcrazyboy68

do u know if it is carb legal?

valeratj

The header is placed behind the engine and catalytic converter stays in place so if u keep your mouth closed and no one sees it, it will pass smog

valeratj

I live in sac too !

CGP06tsx

I hope that was a joke. Most people know that HyTech is the best system when it comes to performance.

EuroRuben97

you mean you gained that kind of power without tuning? well i gues it doesn't matter if its legal who the hell can see it if they pop the hood


can i see that dyno sheet.

valeratj

Of course I was joking. Even a complete idiot would know that HyTech, TODA and Mugen are the best/top quality products.

valeratj

Yes. no tuning at all. how do I send a pic? not much experience with this site. The line on dyno sheet cuts of at 6800 with only 171 WHP.... So on the 2nd dyno sheet (just 2 printed lines) it shows 174WHP. I was a little confused myself.

shaang

Hytech set-up = 195 peak wtq on a dynopak = 186 peak wtq on a dynojet. That's with approximately 8% drivetrain loss on the dynopak and 12% on the dynojet. I'll post my dynos as soon as I have time to get it dynoed.

valeratj

195 with exhaust alone??? are u serious ? wow

shaang

Not just an exhaust system. Hytech set-up consists of hytech header/cat/mufflers. Add the comptech icebox, UR pulleys, 2 heatshield gasgets, 06 ITB which is 64mm, 06 IM, 06 intake tubing, 45 degree VTC, and a custom reflash tuned for the hytech header.

EuroRuben97

Do you mean ITB's as in individual throttle body's and your only making 190-ish or was tq either way thats tight.

HI OFECR

Any problem with the header hitting under the car Noise ELECT?


How much louder would you say your car got under normal driving conditions ?

shaang

ITB = intake throttle body

JTso

iTrader: (2)

The known acronym for individual throttle body in automotive terms is ITB.

valeratj

No issues so far. Car's sound just got a bit deeper and a tiny little bit louder. I love the sound change, its not loud and useless like muffler and way less annoying at high revs.

HI OFECR

TB = throttle body


ITB = individual throttle body



When you are talking throttle body's intake is usually assumed.

Audioserf

Nice gains. If you get sick of the hissing (I did), get a Vibrant flexpipe welded in place of the Topspeed one. You keep your gains and lose the hissing for around an hour's labor at an exhaust shop.

DAYTA

Dynapak dynos take measurements from the hub (not the wheels), so they typically read 10% higher than Dynojets due to the lack of rotational mass from the wheels being run. Thus, if you're at 195wtq on a Dynapak, you'll probably be closer to ~175wtq on a Dynojet.



Wow, along with the Hytech exhaust setup, machining the VTC mechanism apparently really adds some nice power. Please post your dyno when you get it because those would be impressive numbers if they are correct .

valeratj

Hehe, I am starting to get sick of it. Thanx for an advice

shaang

I beg to differ... take a look at a totally stock 2004 tsx dyno done on church automotive's dynapak, same exact machine that I dynoed/will re-dyno on:

From hondata's tuning the tsx article:

Tuning the TSX

184hp/165tq

This is where the 8% drivetrain loss is seen.

On the exact same dyno I'm putting down 195 peak tq. Do the math.

shaang

In other words, if I were to dyno completely stock on a dynojet, then again on a dynojet with my current set-up, we would expect to see an approximate gain of 30ft/lb peak tq.

You guys have seen my dynos a few years back when I first got the Hytech set-up. I've been away for a while, now I'm back and I've added pulleys, 06' parts, and 2 heatshield gasgets. I will redyno soon, but based on my previous runs and TSX2345's last dyno runs (all at church's AND both cars equiped with Hytech set-ups) I'm pretty certain I'll be putin down around 225hp/195tq to the hubs.

Without the 8% drivetrain loss = 245hp/212tq at the flywheel. It sure feels like it behind the wheel!

shaang

From a few years back, in case some of you newer guys to the site haven't seen this:

https://acurazine.com/forums/perform...ll-set-up.html

Sorry but no more pics for now. The web host I was using since then no longer exists, and I gotta dig up my old dyno files...

DAYTA

Your initial reply makes it sound like you're pissed that I'm questioning your expectations. However, I'm fairly confident my math is correct.

This is taken directly from the Hondata article that you linked in your reply:

Also, based on a large pool of dyno runs posted in the "TSX Dynos" thread, a stock 2004 6MT TSX hits between 150-155wtq on a Dynojet. If you take the average of that range (152wtq) and calculate the ratio to Hondata's dyno (152/165), you get a proportionate difference of ~8% - which is exactly in line with the article from Hondata.

If you're putting down 30 lbs-ft more torque down on Church's dyno, why would you assume that'd you'd see identical gains on another dyno that reads peak numbers at 8% lower? If you recalculate the gain based on the ratio above, it'd be closer to a 27.6 lbs-ft gain on a dyno jet, which when you add it back to the average torque numbers hit on a Dynojet gets you to about 180wtq (right in between the 175wtq and 186wtq you and I listed).

Again, this is all hypothetical since you haven't made any dyno runs with your new parts, so get that done first .



...back on topic ...

shaang

You're initial estimation of 175wtq is 10wtq less than my estimation. Your SECOND estimation after actually running some numbers brings you within 5-6wtq of what I'm estimating. 5wtq makes a difference let alone 10wtq. Anyways, its all talk until I put down some real numbers.

valeratj

Latest update: my MPG has increased by 1.9 after I installed header. According to my on board computer ( yea yea I know it overestimates, but still gives a vague idea of actual MPG) I did 34.5 MPH hiway, I just tested the car on freeway again and got 36.4

carmagnut

Wow. Thats pretty good MPG. I have an 5at 06 and have 44K on the car. Mileage from day 1 has been hovering around 27. I used to do more local driving but now am racking up the hway miles. always sunoco 91 fuel.

valeratj

Thanks. My city mileage is terrible. I manage to achieve about 24 MPG when perform combined driving. Always Chevron 91
