is this true, if yes what kind of headers - comptech?

NYZGREATST

no no, more liek 20-25 i believe is more likely. all headers will give you the same output but its quality. i got the cheap OBX ones figuring even if they crack they are still 800 cheaper then comptech

MikePA

Go to the CompTech website. They have a dyno graph containing all the information you'd ever want to see. Hint, headers add no where near 30 hp, 18 hp maximum, and most of that is gained at 6,000 rpms and above.

By the way, all headers, regardless of who makes them, provide the same gains.

sbuswell

18whp equals about 21-22HP which is what headers companies will advertize. We have AT's so we lose close to 20% HP to the wheels. MT's lose about 15% so they actually achieve more HP at the wheels for the same car and engine. Header companies claim 25HP. That may be true, but WHP is closer to 20 maybe less. Still 18-20whp is a lot and you will feel a big difference. Headers start producing more power way before 6000rpm's BTW. MikePA you probaby have a 00-03 tl, i have a 99tl and feel a huge difference at about 3750-4000rpm's all the way slightly past redline 6500rpm's. Still a 00-03 tl you should start feeling the power at 5000rpm not 6000 that gives you no room at all for the fun.

remember the type s gains are higher than the dyno chart tl-p

car_lost

type-s gains about 32whp from headers.

MikePA

I quoted dyno figures directly from the CompTech web site for a 99 TL.

WiLLs TypE S

I was told for I/H/E you get around 25-30whp for the Type S.

SLAMMED_WDP_TLS

I dont think so. There is NO way you get 32WHP outta headers. max 30 HP but WHP NOT the same as HP. WHP is how much power you put down on the ground and there is not WAY you get 32WHEEL Horse power from headers. I have I/H/E/P and the car pulls hard. Dont be so caught up on the numberlets jsut say you will FEEL a harder pull with Headers. You definitely will. The thing about headers is just the quality of the headers. how well they fit and if they have any leaks or fitment issues. all the headers out there will give you almost the same HP. Hopefully that helps

No way in hell. Don't believe everything ebay tells you.

Satisfactory/average is about 15-18 to the crank not the wheels. You can lie and say you're getting a hell of a lot more, but... you're not and any dyno will prove it.

car_lost

an old thread:

https://acurazine.com/forums/showthr...ht=header+dyno

26-28 at the wheel... peak.

car_lost

you wont because you dotn have a type s. a type s will give more gains... plain and simple. i didnt pull 32whp out of my ass or off ebay. i know i saw it somewhere on here though.

ou sig

20-25 WHP increase is the norm of our engines - more toward 25 for the Type S. Dyno proven

car_lost

here you go... http://www.comptechusa.com/images/dyno/2000CLSplot.pdf

read it and weep. look specifically at 6600 RPM.

and the thread that came from: https://acurazine.com/forums/showthr...ht=header+dyno

WiLLs TypE S

So if the Header does 25-30whp on the Type S...can I believe that I/H/E will get me around 30-35whp? I know that they work together...so it may cancel each other out...so thats why im saying can it be 30-35whp?

fsttyms1

its not ebay its fact! previous members and comptech had dynoed the type s around 27-30 hp

MikePA

CL Type S --------> Click Here

5,600 rpm and below, the gain is 6 hp or less.
5,800 rpm and above, the gains start at 13 and peak at 32 hp at 6,600 rpm

TL -----------> Click Here

5,500 rpm and below, the gain is 4.5 hp (3,750 rpm) or less.
Above 5,500 rpm, the gains start at 7.3 hp and peak at 17.9 hp at 6,750 rpm

You people shooting this down need to do some searching. The Comptech headers have been out for over 4 years now...about as long as the CL-S has been available... and MANY people have done dynos.... average gain is 25-28 HP... at the wheels. This is just a fact, and has been the case for these headers. Even the companies who make knock-offs (OBX, Stone, etc.) get 23-26 HP gain at the wheels... all dyno proven.

You can choose to believe it or not, but the bottom line is that this has been proven with many, many dynos from members dating back to 2001.... so do a search if you need more proof.

car_lost

where are the nay-sayers now?

MikePA

Most of the 'problems' are caused because people fail to distinguish between TLP and TLS models. They just say, as happened in this thread, "I hear headers get you 30 hp."

This thread...

The max gain is around 30whp. The PEAK gain is around 20-25whp.

MikePA

Perhaps this thread, or at least the links to the CompTech site, should be a sticky. This comes up all the time. From people using their butt dyno or mis-remembering other posts, every thread ends up the same.

It'd be nice just to point people to the site where the dyno runs are.

SLAMMED_WDP_TLS

Take a CLOSER look at the comptech site. So you are telling me that putting on the headers will give you max 32WHP which the SC only give you 34-4o WHP??

http://www.comptechusa.com/store/med...ls6auto_sc.pdf
http://www.comptechusa.com/store/350062tl.html

This dyno graph and the ad posted by COMPTECH themselves stated WHEELHORSE POWER gain will increase 34-40 WHP with s/c. By statiing that and what YOU have stated, the headers, which by you stated give 32WHP and the s/c will only give you 34-40WHP. In real life header WILL NOT come cclose to the power of the SC. The comptech dyno graph stated WHP for the s/c but never for the headers or exhaust.

samkws

i have a 2002 TL-P with comptech H/E/I

so how much gain i should have?

MikePA

The links I posted, both for the CLS and the TLP, state WHP increase for the headers. Taking time to compare the s/c with headers and the headers alone, shows that the s/c increase hp gains at the lower rpms.

It's not as simple as just looking at max hp increases.

MikePA

No offense, but visit the CompTech site and discover for yourself. There are a number of dyno graphs there.

People not reading the graphs for themselves is why threads like this happen.

Listen up rookie, you are wrong, plain and simple.

The headers will give you a MAXIMUM gain of 30whp. END OF STORY. At PEAK you'll only see 20-25.

The supercharger will give you 30-40whp ON TOP OF the gains you see from the headers.

My supercharger gave me 295whp; a hell of a lot more than 30-40whp over a stock CL-S.

Dyno's have been posted on this forum time and time again. A bone stock Type-S makes around 190-195whp. With I/H you'll put down around 220whp. With exhaust and pulleys you'll make closer to 230-235.

samkws

they do not have a dyno for all intake, exhaust and headers for the TL-P sucker

MikePA

They have one for exhaust and headers. Did you forget that intakes are just for noise, sucker?

samkws

you are DEAD WRONG

comptech icebox is quiet in normal operations and it gives a lot more low end torque

for a TL-P it has about 7-10whp gain

fsttyms1

they do moew than make noise. the comptech and aem have dynoed at 10-11 hp

WiLLs TypE S

Someone just close this thread...lol..its getting to violent.

keepingitclean

I might get flamed for this but why dont we start estimating quarter mile and 0-60 times instead of horses on wheel. Isnt that what we all care about?
For exmaple, how fast should a tl and tl-s be expecting to run with each mod

I was thinking with headers and intake, a tl-s should be expected to run 14.3-14.5 correct me if im wrong

samkws

a stock can do 14.5 without a problem

MikePA

No duh. I have one, I know.

Make your mind up, are we talking hp or torque?

What's your source for this information?

CompTech quotes 14 hp and 13 ft lbs for a 2003 CL-S 6 speed. No information there for a TL.

WiLLs TypE S

It all depends if you're lucky and pick a fast TL-S from the manufacturer. A stock TL-S should do high 14's to low 15's. 0-60 is around 6-6.3 seconds. With Headers and Intake and with good tires, should pretty much get u down to mid 14's-high 14's, and high 5's to low 6's for 0-60. I have seen a TL-S with I/H/E run low 14's, with the setup, but then again..it all depends how you launch, and what tires you get.
For a stock TL-P(5 speed), I have read and heard the 0-60 is around mid to high 6's. 1/4 should be around mid 15's to high 15's. With intake and headers should get u low-mids 6's for 0-60, and around high 14's to low 15's. That is why they say when a TL-P has I/H/E it should be where a Type S should be.

samkws

extxxz's 99TL beats the TL-S numerous times

he has a pretty much same setup wtih mine but a 4 spd, except he got pulleys which adds a few hp more

samkws

stop being a jerk dumbass, didn't you said intake is just for sound only?

and i am talking both hp and torque here sucker, and stats show there's a huge gain for the type-S motor AS YOU QUOTED, 10whp gain for a reguar TL sounds logical and reasonable since the regualr TL motor is more restricted with the stock airbox, with no restriction it does perform a lot better

i got comptech exhaust, icebox and headers and i can feel the difference by installing them one by one

it makes a significant increase in thortte response ever since i got the icebox, and the headers really gives a huge difference at acclerating in 4th gear at 110mph

ALSO....if you don't like the fact that you are being owned, then don't post here coz your posts really made us laugh by saying this and now that, in fact you don't really know so don't try to be an expert here

Icebox gives you 8-10whp.
