Post the pipe.

Sorry Wob, this one, and thanks for your great reply.

What was the pipe called , was the EngMod project name up at the top.
If I get a dull moment I will update it for you.

Can't see a name anywhere. Here are the EngMod details

Dutchpower, this is a pipe you've tested?
I'm aiming for a tuned length of 820, starting at 35mm with a shallower header than the original drawing.
I have partial measures of a HGS pipe and probably a standard somewhere, are you asking to see those numbers?

Forget the 35 we go to 36 and lost lots of hp
Here you got new exh.

[andreas]

I'll test it.
You built this in Engmod, or tested on track?
And it's for the powervalve yz85?

Both track and dyno

Both track and dyno

Ok, great, looking forward to test it. How do you face it to the duct, it's smaller than 38mm right?

You can make it bigger is also oke

[andreas]

I mean, the cylinder exit on the yz is close to 35mm, I believe. How do you join them?

After 40 years of pipe building using Dynamation , then Mota , then EngMod I have never seen anything make good power with a 1.8* header , nor a 12*/30* tailcone ?
Sure its good to try things that have never been done before , but weird is still weird at the end of the day.
Its like " Stuffing " telling everyone our headers and diffusers should be 34%/68% - never seen one , never built one - why would I , the code says its shit every time.

Make it better Wobb and help ( andrea ) maybe I can learn something after 50 years of making exh.

Send the .pack to wobblywayne8@gmail.com.
Its impossible to optimize any pipe in isolation.

[andreas]

It's fine. Anyway I don't have the data.
Fitted v-force today, with positive report.

Hi there .
Why did you make them (pipe) in section rather than hydroform?

[andreas]

Simply, was never acquainted to that method.
