So where are the dyno's of the Comptech Race header?
So where are the dyno's of the Comptech Race header?
We all know the big daddy's are the SMSP and Hytech pieces.
Best off the shelf JDM header is Toda and Spoon.
Best bang for the buck is DC Sports JDM 4-1, and JDM ITR OE header.
Best USDM header is Comptech 4-2-1
Comptech Race header just as good as the big players SMSP and Hytech? Owners opinion of this header is appreciated.

Re: So where are the dyno's of the Comptech Race header? (Edwin)
Comptech Icebox w/ Stock Snorkle
K&N 2820 Air Filter
Comptech Race Header
Comptech Adapter (Test Pipe)
Hondata Intake Manifold Gasket
Toda Cam Gears (Gen 1; Untuned)
Comptech Street (Power Pro) Exhaust
Hondata S200
Prelude 290 Injectors
ATS Final Drive
Fidanza Aluminum Flywheel
185 whp
126.4 ft-lbs of tq
Big thanks to P1 Auto for Tuning Assitance!
Once I have time to get back to the Dyno I think there is more Tq to be had (Tuning cam gears mostly). Maybe a hp or 2 but not much, could be none but I can have a glimer of hope. This is inline with the Hytech and SMSP users with similar mods.

Well, if um Comptech quite clown around and hurries up with mine, lol I may do a few dyno runs with the Comptech race vs the JDM DC 4-1. My engine setup is semi-build, though, keep that in mind. Alot of the charts with SMSP and Hytech out there are B20 fully build whereas my will only be a 11:1 minor port work with JUN 3's only. Then again, my time is very very limited too.

Re: So where are the dyno's of the Comptech Race header? (BERT-O)
Thanks for input guys.
If I decide to get this header I will graph it against the Comptech 4-2-1 USDM street header.
I hope to improve top end and be in the 195hp range. The PDF file on Comptech USA's webpage compares their street header vs race header and looks like it would do what I want.
http://www.comptechusa.com/ima...r.pdf
183hp with 130lbs of torque sae corrected on a dynojet 248c.
Mods are: Comptech 4-2-1 street header, 2.5" exhaust + high flow cat, k&n filter in stock air box, hondata s200, comptech aluminum flywheel.

Re: So where are the dyno's of the Comptech Race header? (Edwin)
Edwin,
I don't think you will see 195 on stock cams regardless of the header you choose (Hytech, SMSP, Comptech) without loss of midrange. George made almost 200 hp with his setup but lost so much midrange I think they found the area under the curve to be greatest around 190 whp. Austin makes 189, George Makes 190 and I am making 185 and we are all on stock cams.
Not saying it is impossible but just saying be realistic with the goals. I might have missed a mod that will put you there though.

George's set up
George should be in the 210-215 range after the winter mods, that he knows very little about.
Just put some $ aside George and we'll take care of it.

I don't have numbers, but I can say that it's a very nice peice. The welds are extraordinary and it's a pretty beefy unit. I'll complain all day long about the ground clearance, but I haven't dented anything yet. Just minor scrapes. Knock on wood. I love mine, but I'll be moving up to the SMSP after my second build. If they're available.

Re: So where are the dyno's of the Comptech Race header? (Unsung EM1)
I've got one here and two more on the way (they are special order starting Sept.1 and only available direct from Comptech starting then).
Might toss one on the car and see what happens.
how long is the drive from Annapolis to SgT?

Re: So where are the dyno's of the Comptech Race header? (Asahi)
Very true, I'm at 187 on stock cams, HyTech header/exhaust, and cam/VAFC tuning. The cam gears could have been adjusted for more bump up top but the beefy midrange that these sequentially paired extra long hybrid 4-2-1's are designed to give will be gone. Seems like all of us Comptech Race/SMSP/HyTech folks are making around the same power with our bolt-ons only setups.

Len will need something with a BIGGER collector soon enough.....
As for the ground clearance - comptech WISHES they had copied hytech's supreme ground clearance setup... Comptech SUCKS ***. I hope you guys who have that header are at stock height... The first speedbump you don't see till it's too late =
Looks like a quality piece though - if it's readily available and you don't wanna wait on a custom unit, it's good!

I asked this before but forgot... On the famous great header test, the comptech that they tested, was that Comptech Race? Possibly an older design?

Well Comptech traded ground clearance for not needing to shave the stiffener, which is required for the better ground clearance on the HyTech.

Like Surfer X Mentioned Ground Clearance is an issue but they did it for a reason which you left out. There is no cutting of the stiffener and the install without removing fans is possible.
To be brutally honest, Hytech has ground clearance but crappy car clearance, Comptech has good car clearance and crappy ground clearance. If I recall correctly SMSP stock cam car is making the most power, requires NO cutting and has more ground clearance than Hytech or Comptech.
Take that for what it is worth but I am lowered 1.25" and have NO issues with hitting my header. It is closer than comfortable though. Some suggestions are don't lower the car too much and keep the front shocks fairly stiff if you have damping adjustability

NO. THE HEADER IN THE TEST WAS NOT THE RACE HEADER.

Hey Edwin... I have a crazy idea.....
Why dont you pay me the money you owe me, before you start purchasing race headers.....
Just a thought.

Bad comparison, I'm sure that if I had a ported head the story would be reversed, not knocking George, his car, or SMS, just a bad comparison. The numbers between George and I are quite close...I'll eventually have the 200whp, but I'm not as power hungry as I used to be, to me it's more important to learn how to properly control the power than actually having it.

I hear or recieve any emails, im, or phone calls that day or to this day from you about it.
All I saw was you the highway that day and that's it.
My condolenses to you and and your family. I hope for a speedy recovery.
Let's take this into PM.

I wasn't in anyway trying to knock anyone. You have a headgasket, George doesn't. Not sure the extend of the port work GK has but he has stock injectors and we don't. Plenty of subtle differences but enough I would call a lot of it a wash. Infact I would say the power difference would more likely be luck of the draw on how strong your motor is when we get to thjis point.
Heck you made 189 vs GK 190 (IF I am remembering numbers right) so that is just as easily margin of error between Dynos.
I do like the last part of the statement. I can relate.
