HPC is not cheap :)

Shiroi is right here. Heat wrap does crack you headers after a while. I've seen them crack in 6 months. If you don't want this to happen but cut down the heat in the engine bay, HPC coat it. Looks the parts and doesnt have any cracking problems. There's only slightly a bit more heat but the difference is to small to feel it.

On top of that, buy a better header as cheap ones tend to crack after a while

neither is heat wrapping, but the cost about the same

You also forget the poor welding jobs, though from the last copy I've seen made locally, I may have to eat my words on that. :P

LoL. Thats right. Seen that happen too.

Yeah J101, HPC coating is not cheap but even though it cost more, its better to do it right the first time. If it doesn't look right the first time round, it probably isn't. Heat wrap is about 2/3 the price of HPC. I don't see why people are always saying HPC is so dear compared to heat wrap.

I think over here, the transportation costs are a problem.. which is why the HPC is so dear to Malaysians.. They're essentially forking over money for transport rather than the product itself.

what about JDM ITR 98 4-1 header anybody know about that?

 

[hattech-v]

yeah... i know about it.. n i got it... if interested please visit http://www.avantech.com.my

Good information here:

"In summary, plan where you want your peak torque will be and how wide your power band will be along the rpm range. Then choose a header-cat-exhaust system with the design characteristics that facilitates that goal.

You may get more midrange power but give something up at the top rpms.

Or the opposite, you can plan that you want more power in the upper rpms with some compromise losses at the midrange rpms."


good words from page 3. the words "plan" and "goal" are often forgotten by the user due the excitements of the brand names especially.

wonder why honda engineers fit in 4-2-1 for B16B & 4-1 into 98' B18C even both use same cam? thats mean they want to achieve peak power at lower rpm for B16B compare to B18C? But B16B achieved the peak hp & torque as high rpm as B18C.

something like that, but peak power also based on piping size.

 

[Enthusiast]

mind to elaborate more on that bro shiro?

 

[shiroitenshi]

Sure.. let me organise my thoughts first. A bit busy with work these couple of days.

 

[J101]

lets look things as an overall. b16b is a destroked engine. destroking will reduce torque output, which directly reduces power output, but in this case the better rod/stroke allows for higher revs, and the power comes directly from revs alone to overcome power/torque lost from less displacement. you see more CTRs on the track rather than ITRs. same concept goes to the touring cars where they destroked the motors to get 300hps with the high revs.

just my 2 cents.

thanks for the explanation. u mean CTR produces the power by revving high, then wonder why it is fitted with 4-2-1 instead of 4-1? Is it the 2.5" collector with allows it to achieve the peak power at higher rpm?

 

[J101]

because of the low power and torque output they used the 4-2-1 rather than the 4-1. its all a give-and-take design. you dont want to slug on the pickup especially with a 1.6 factory engine.

thanks for the explanation. Will the Spoon 4-2 better than CTR 4-2 beside spoon one look nicer?

 

[J101]

if money can spend, why not. take the spoon then.

i'm curious about one thing....for those who uses stainless steel header and vented CF hood....when it starts to rain and water drops onto the hot stainless steel header thru the vent, will it somewhat damage the header in the long run?....like crack or sumthin'.....
