Kamikaze*********

I was curious if anyone had any experience with it and on the dyno NA not supercharged?

I can't see it being too bad... mid to upper range.

 

I think it looks great especially how it comes in a 4-1 design and the price is not bad either. Someone must have one!!

 

i dont have a dyno,,,but i did run this header un-tuned and notice little differences at all....seemed to be bad down low and pick up the same at wot...who knows though but dyno can be shitty

 

I had a Kamikaze on my B16A. It was absolutely BALLISTIC on the top end!!! With no loss (maybe even a gain) in midrange!!!

Now I have an F20B. Since the results were SO GOOD on the B16A and they are both top end engines, I will be getting the same (2.5 downpipe/collector) header for this motor.

The F20B is of course a slightly destroked and smaller bore version of the H22A, so it should boost performance somewhat similarly I would think.

 

mmmm curious as well

 

stay away from this header for an allmotor h22

i had one, it sucked, you will be pissed after you feel the loss of power

i had a dynogragh way back in the day but i nolonger have it

30+ tq loss (dynojet) through midrange no joke

peak power was slightly higher than stock header but not much

 

30+ torque loss?? Come on dude, REALLY??

Find any dyno (on H-T or the net or any other resource) of ANY engine, where a 4-1 header losses 30 ft. lbs. of torque to a 4-2-1 design.

...I DARE YOU...LoL

 

whats wrong with the header you make and sell?

 

are you kidding me

tri y headers are good for tq, 4-1 headers are good for hp, experience will tell you this.

yes really, huge *** dip unlike anything i have ever seen before. im just posting as a public service, if you like i will gladly go away and not try to help you freshman save your hard earned money to make better choices anymore.

the header is not designed for allmotor, its way too big and huge tq loss is the result.

 

Actually, I thought you were kidding.

A Tri-Y header is NOT good for 30+ in torque over a 4-1. No matter which configuration you choose. Even though the Kamikaze is primarily designed for super charged setups, it makes for a great header on high revving NA engines because of the primary length. The Kamikaze is also not that big. The primaries are 1.75". There is even a choice between a 2 and 2.5 inch collector on the B Series header. I do not have a comparison dyno of the header from my previous header. I do know however that there was NOTHING in the range of a 30+ torque loss!!! EVEN ON A B16A!! A true public service would be for you to provide evidence of what I consider to be a ridiculous claim.

The included attachment and following info is said evidence:

The LOWEST torque output of any of the 4-1 headers is 122.
The HIGHEST torque output of any of the 4-2-1 headers is 132.

THE HIGHEST TORQUE OUTPUT (139) OF ALL HEADERS WAS PRODUCED BY A DC 4-1!!! Beating both Hytech and SMSP Tri-Y headers.

The following "CLASSIC" header test is also indicative of a true comparison between a Tri-Y and 4-1.

STOCK JDM ITR swap, EG CIVIC.
NO MODS, stock airbox, stock manifold, stock everything.

PLACING:
1st RMF NARROW 4-1 185.61whp/128.49TQ

2nd SMSP Prototype 4-1 184.70whp/128.98TQ

3rd SMSP 4-2-1 182.38whp/123.82TQ

4th ANR w/Merge 181.05whp/125.79TQ

5th DTR B-Unit 180.82whp/125.46TQ

6th Hytech Production 180.63whp/124.19TQ

7th DC JDM 4-1 174.24whp/124.04TQ

NO LOSSES IN TORQUE HERE EITHER!!! EVEN THE SMSP 4-1 PRODUCED MORE TORQUE THAN THEIR VERY OWN TRI-Y.

No dude, I do not want you to go away. H-T is for ALL to share their knowledge and I truly respect and welcome your insight. I am VERY FAR from a freshman. I am 39 years old and have been tinkering with Hondas since 1990. Dont let the amount of posts and join date sway you. This is my second stint on H-T.

Best Regards

 

Does kamikaze only make one h22 header? The one with like 11-12" primaries?

 

Yes only one. The only options for the H22A header are the coatings. The primaries are all the same.

 

I think ESP is trying to push his H22 headers here.

He makes them you know.

And you know, what, I think I will try one next year, I got everything else he makes lol

 

idk, do you have a dyno of a Kami on a H22? Just wondering.


Well, half of them.

 

[QUOTE=A Blue Lude;43111901]idk, do you have a dyno of a Kami on a H22? Just wondering.


No I do not. I am new to the H/F camp as of February.

My interest in this thread was to refute the suggestion that any Tri-Y will outperform a 4-1 by 30+ ft. lbs of torque. As stated previously, I have an F20B at this time. It is COMPLETELY stock except for the removal of the resonator box. I will be dynoing my car at Super Autobaccs next Saturday, July 31st.

Originally, I was going to dyno it to see what a stock F20B with a fresh oil change would produce and also to get a base line for reference purposes to compare with the modifications that I plan on performing. The first two mods WERE going to be a new OBD-1 ECU program that I have in a P28 and a Buddy Club Spec III catback for my Accord SiR-T that I have been waiting a while to install.

......THAT HAS CHANGED......

After becoming involved in this thread and to satisfy my own curiostiy, I am now compelled to dyno the engine in its completely stock version and then add the Kamikaze header ONLY in order to see the results.

I wont be able to order the header until the middle of next month, and of course it has to be shipped here to Tokyo.

I will post the dyno results and some pix in this thread once I have dynoed with and without the Kamikaze.

Stay tuned.

 

Stay away from Kamikazi header , that thing is a joke. Also the above tests was on a Civic? Those vehicles can run a 4-1 , not the prelude. The best header for a prelude is a 4-2-1.

The prelude is a torque beast , so dont be too worried about torque. It needs more top-end anyhow. I had great results with the greddy header , not sure if their still around. Either way just get the hytech replica.

End of story.

 

LOGIC MUCH???

Since the H22A is a torque beast and you DONT need to "be too worried" about torque, then you would WANT to improve the top end with the use of a 4-1 header....

Secondly, the F22s and F23s are even GREATER torque beasts than the H22A.
Hhhmmm.... What does Bisi use on those "torque beasts" of his to dominate the competition??????
Hhhmmmmm, I wonder....

Thirdly, the 4-2-1 configuration is NOT designed for performance purposes. It is designed strictly to be a COMPROMISE for street driven vehicles.
That is why OEMs use them. It is NOT intended or optimized for all out performance applications.
NAME ONE RACING SERIES THAT USES A 4-2-1 HEADER???

Lastly, you did see the data, right??? The B18C and the H22A have exactly the same rod ratio. This means that breathing wise they will have the same potential and power production characteristics. If a 4-2-1 is NOT the best header on a B18C then it WONT be the "best" for the H22A either as you have suggested.

Just some of my logic.

Best Regards

 

There might be some fuzz in the logic, but more dynos are always great to see and useful.

 

LoL! Some fuzz, huh??

Yes, I agree with you that a dyno plot is the best choice for providing emperical data. That is why, great results or poor results, I will be conducting my own experimentation with this header. If for some reason it fails to perform as it did before then I will opt for something else.

My only concern is that the header is designed primarily for the high end. That being said, I will have to install the P28 and get a baseline beforehand because of the higher redline. Then counduct the header test. This way the header will not be limited to the factory redline.

 

On a stock cam motor the stock fuel cut will be plenty to see what is going on - you won't be making peak power after that I think.

Still, more RPM data is helpful, of course. And it's not like peak power is really important anyway.

 

What NAH2B is talking about could be true, I was just curious if anyone had any dyno charts to show of this header on a NA motor....

I like collecting H22 junk and I purchased the top half off ebay for 30 shipped... Flange it self it self is 2.5" the ID of the piping which is slipped into the flange is 2 1/4" this one is polished.

What may be the loss of power is because the merge is too close and the runners are not long enough length wise... there is a certain amount of length the runners need to be for optimal flow and power like a normal 4-2-1.

exactly

the primaries are too short and the collector itself is garbage.

for top end power you normally want 20-24" length primaries

for low end and midrange performance you want alot more and the tri y is perfect because the design itself adds length to the header.



i never measured the length because i didnt know better bcak then, but i can tell you they are VERY short. if the info posted earlier is correct and they are 11-12" why the hell would anyone want this header LOL!!! unless of course you just dont know any better like me 10 years ago

fyi here is a good 4-1 H header:
