can anyone please comment on the differences of the Spoon header vs the MG racing? I mean as far as theoretical power gains... ie high end, low end? etc. If explaination can be included, that'd be great... just trying to learn a little here.

Spoon:


MG:


It's clear from the picture that both are 4-2-1, but the MG has a lot longer "2" section where as spoon is a lot shorter. Just wanted to know how that effects the power range... things like that.

thanks,

You forgot this:

 

My take on it is that each will have a different power curve with peaks at different RPMs and torque curves that will be a bit different.

We already got Mugen's numbers, I do wish to have someone (like Prolene) dyno his full Mugen setup at my dyno place back to back with mine (Spoon/Mugen hybrid setup).

 

Also Shing, a minor variation in intake may have a dramatic effect on the power curve. So when we dyno all three, all three cars should be as close as possible in terms of the intake portion.

For example: Prolene's car is a perfect candidate for back to back dyno with my car since his airbox is stock with JR filter and P-flow TB bore, my car has the stock airbox with JR filter and Spoon TB.

 

A little off topic, but related
I was also wondering why no one has tried a 4 into 1 header just for the hell of it to see what the difference is(yes I am thinking of having one built) If I do get one built, would anyone in CA be willing to dyno on their car VS. Richards? Since I live at altitude my dyno numbers are all screwd up. Or mabey I will drive out to CA and dyno my head work at the same time.
Sugestions?Comments (4 into 1 header)

That is the theory, but I have seen instances on other Hondas where that was not the case, and the 4 into 1 ended up producing more torque and power through the entire range (ITR in particular-dyno proven). I know that the cars are not the same, but I am just trying to think of other potential avenues, that may not have been explored. My thinking on this is that strictly because the factory used a 4-2-1 setup, many manufacturers may use this as the baseline as opposed to bothering with a differing set up. (increased r+d, noise, I have no idea???) If this is the case then it would be great to have the option of two types of headers.
Am I the only one who thinks this? Has the 4-1 set up been tried, with failure (power loss)?
Feed back is appriciated

 

I see what you are saying... well, I just wonder why the S2000 headers have to cost so darn much, I mean $1300-$1500 for a header is like WOW. I think the DC sport titanium race header(for the B18C) is $1500 and it actually makes mad power.

I'm sure those other headers "make" (I prefer to use the word "release" or "free up") mad power because the stock headers on those OTHER cars were most likely either restrictive or wasn't optimized in the first place.

I've seen 4-1 headers for the Accord lose power down below, but I don't know about others. Like I said: you change the length of your intake piping, and it's a whole new ball game. This is what "tune" is about, right? There's no "right" answer really, it all depends on what people are looking for. I look for low end torque because I drive in traffic and rarely stay up in the VTEC range, another friend of mine who race his car all the time could care less for anything below VTEC. So what works on my car will most definitely not work on his car. It all depends on what you want and what you are looking for.

Take a look at the dyno graphs when we do get them, you'll see that the curves are all different among the headers. If a set of headers made "mad power" up in the top end, netting an impressive amount of HP gains, it might not be as hot down below and may "lose" power down below - but that would be GREAT for my racer friend who cares mostly about the top end. Whereas for me, Spoon's headers gave my buttometer a good kick in the pants sort to speak when it came to low end power, but I can't feel anything in the high end.

I agree with you on that different headers will make power differently. I was looking for some reasoning as to why it did that. In other words, I wanted to know why the spoon made more low end than other headers for example.

BTW Richard, the more I look at that picture, the more I want to get one.
