i think raspy is more like it... any header ive ever heard makes the car sound more raspy.

 

A Sound or video clip from roaring Vtec would be great Filmed from opened hood?
Just a sample of what we are expecting?

 

I'l get you a sample, lets see if my camera's recordgina abilities are any good.

 

yea thats what i am talking about...
By the way..
If i get it right.You had ricks header before...
I know that BUTT dyno is a hard thing but have you seen any difference?
Performance whise?I took my Cat off and felt better acceleration on Vtec but that lasted a week or so when it came normal....
And in the end -comparison on subjective base between two?
And the dyno will tell a lot.

Ricks definitely gave more power, i never dynoed it but butt dyno said alot. Mid-range and top end i really feltt he improvement. The megan doesn't seem exactly like Rick's but rick added like 4-6 whp on their dyno, maybe megan's improvement (if any) is not as much.

 

that sounds disappointing...

just look at the views this thread has, we have all be looking at every new post hoping for good gains. Knowing the gains of Ricks/Mugen and hearing that this feels like less doesn't give much hope.

Oh well, J's stays on top I guess

 

Lets Keep the Hope Alive...
Only the Dyno would tell.Well lets hope for the best... Gain all over..But no Lost hp.
In my opinion the S needs Power Up to as it screams its way to top.
Mid power like the mugens or Ricks is good for track use I think.
You pull out of corners with mid Rpm and floor it on exit and that's where mid counts I think.
But for us Street racers Top is always welcome and we Squeeze every bit of Rpm Left and This means TOP power....
As far as gains I think on our cars which are 200whp stock 5 hp is very hard to notice...The only thing that makes us believe is the Sound deception of the Aftermarket installs.Louder- must be quicker.
But most products are improvements and Mind peace that its not stock
Anyway 5 hp is 5 hp. No matter how expensive it is or how cheap it is.
Lets keep the hope alive and see the dyno.If not us Megan will be disappointed also.we are the largest buying S2000 group and if this proves to be poop I think they will be left with lot of S2000 headers.

 

well the design of this header doesn't look to be one which will increase the top end. a more free flowing 4-1 should do that. With this initial report, i'm kinda glad i got lazy and didn't pull the trigger. Final judgement will be reserved for after the dyno results. Thank you Roaringvtec, you're a good man

 

This is the email from megan company

That was a pretty strong email there. The dimensions of the engines
remained the same. Same blocks, same cylinder heads and bolt patterns. The
internals of the engine was all that changed, so the headers will work with
all the S2K's.
When we went through the designs of this header we started off with what we
knew. The basics of headers, equal length primaries, smooth bends/welds,
larger diameter primaries and collector and to keep the velocity up by
allowing the primaries to be straight for awhile before bending.
After we get it on the car and do a few tests, we tuned it to get the
power where we wanted. We weren't looking for peak numbers, we were aiming
more for a flatter torque curve. The S2000 already has high-end power, but
it suffers a lot in the mid-range. That's why we went with a Tri-Y design
over a simple 4-1.
I don't have the dyno graphs with me so I refuse to quote any numbers.
When people quote numbers it's usually under the perfect circumstances. It's
with below room temp intake, low-drag, low-altitude, and a cool engine bay...
so don't believe everything that you're told.
We also NEVER copy other companies and refine things. If that was the
case then there would be no research and development... in which I wouldn't
exsist.

^^Interesting. I might have to buy one. Did I see a group buy in here? Someone had the hook up.
