ok everyone,

i just came back from a the dyno shop and the results are in. sorry for the crappy picture, i had to scan it. acouple things to remember.

1. these are SAE corrected
2. both runs were done with 19's on
3. both runs were done with the engine at operating temp to simulate normal driving conditions
4. car has 92,000+ miles
5. both were 3rd gear pulls
6. the gains are from AEM CAI, UR pulleys, and AW headers



blue - stock
red - AEM CAI, UR pulleys, AW Headers

hp gains 227-197 = 30 whp
tq gains 192-175 = 17 lb/ft

notice the low, mid, and high rpm gains. there very smooth compare to the baseline pull.

assuming the pulleys and intake gain 10 to 15whp, then Aw headers are doing it's job providing 15 to 20whp for a total of 30whp. getting AW headers for $300 shipped to my door, it's a bargain.

also i calculated the drivetrain loss from the baseline pull is equal to 24%. using this percentage i calculate that my car is producing around 314 flywheel hp. which means flywheel gains with three mods are 54hp. that's pretty impressive.

 

Sweet!

How much HP should a CL-P see from these headers? 15-20hp?

 

i'm not sure, but my friend has a tl-p and he's getting AW headers shortly. so hopefully he'll post his results soon.

 

Nice can't wait!

 

awesome i got aem cai on my car, and i got the AW headers in my trunk, goin on tomorrow... this is awesome news!!

 

good #'s. nice to see some data

 

hmmm not too bad. whats the website again, and who do i contact

 

i think the #'s would've been different with lighter wheels. but these are similar #s to ct headers IMO

 

Real nice numbers. I think you've found a worthy replacement for the Comptech's.

 

i got mines from ebay, but here are a few other sites

http://www.speedstash.com/headers.html
www.wheelsnext.com has some too but the site is down right now.

 

$425 and $475?

Thought they were only like $300??

 

on ebay i got them for $300, but there hard to come by. you might have to wait awhile to spot them. search for 98-02 accord v6 header, that's what i have on my car.

 

thanks for the dyno bigguy.....i have the alpha headers and the UR pulley waiting to be installed

 

i finally got mine, gonna instal them in a couple of days

 

Finally some hard #'s.

I got an Icebox with the AW Headers.

I wonder if my gains are the same as yours bigguy.




I shoulda got a dyno done.

 

That is quite impressive considering you don't have a flywheel

 

why doesn't he have a flywheel?

 

Automatic transmission. Horesepower is rated at the crank.

I could be wrong though... but I'm pretty sure.

 

Nice numbers. I just got the alphawerks headers on my TL-P not to long ago and bought them of a local guy doing a group buy for $300. They are definitly the bang for the buck. I don't have the money to do a before and after dyno. So I'm just going to wait to put my NO2 wet system in before I run it.

 

nice work, and you did it all so fast. when i saw your car in july it was close to stock.


we on for saturday?

 

auto or manual both have flywheels

and even when i took my old car to the dyno which was manual they give u WHP, since the only way u can really get flywheel HP is by dynoing the engine itself without the tranny

 

Do you get any kind of resonance or weird noises with the AW headers like the other brands have been reported to do ?

 

I assume they have no 6 speed version correct?

AW headers + Icebox + Unothordox Pulley would be 250whp/220wtq on a 6 speed, and all for about the same price as a set of CT headers.

 

Nice Numbers

Time for a 75 shot to give MattG a little competition

 

i am in the process of ordering, do the welds look better than obx? fitment is perfect i hear, and stock gaskets i should be using, and the alpha werks emblem should be on the rear of the header.

 

great #'s

and joe all those mods are still way cheaper that the comptech headers

ur crank 200
intake-250
headers-300

total 750

headers: 1100

 

Congrats! Nice gains.

 

Well I figured $400 for the headers cuz the intro pricing is done with and you know ppl on here are gonna have it installed by someone else, so theres a couple hundred bucks. Either way still a much better $$ : hp gain than the CT's.

 

[QUOTE=Renegade]... and stock gaskets i should be using....QUOTE]

isnt it bad to re use the stock gaskets?! i got new gaskets w/ the headers.......

 

no noise what so ever. the only thing that got louder was the intake, but that's a good thing.

 

that's next on my list. i'll have to see what i put down at the track on saturday.

 

looks exactly like the comptech headers from what my friend (acura tech) said. welds look good. there was no fitment issue and i used the stock gasket. yes, the emblem faces the rear of the car.

 

i kinda got alittle out of hand. but it's worth it. see you on saturday to

 

This is awesome, a dream come true, those 19's hold the dyno back a lot, i think the alpha werks perform just as well as the comptechs 25 hp 20 torque, and since no one has had trouble with fitment and the welds look good its awesome, especially the price!

I did hear that the honda accord 98-02 v6 alpha werks headers fit the same on the cl, is that true, so its the exact part as the cl type s header made by alpha werks?

 

Damn, us 6MT drivers got the shaft, AGAIN!

 

same exact part for the cl-s. i checked with nexusindustry website, exactly the same

yes you should use stock gasket, they're better than the ones they give u.

-rez

 

yes it's true, there the same exact part#.

 

anyone know if these alpha werks headers come with any warranty if purchased from nexus themselves, because I am getting some tomorrow for a good price, but I dont think any warranty comes with it.

 

any resonance with the AW headers? Are they smoother than the OBX's?

So would total HP become 290HP in bigguyonbike's case?

 

I just got my alphawerks headers in today. I can't wait to install them.

How hard is it to install these headers? Does the alphawerks plate go in the front or the back?

Thanks
