straight to the pool room!
Well done man...
They look fckn amazing! Engine bay pics!

+1 huge patch
they look amazing just wondering why does it have a slight funnel shape (looks like it goes from 2.15-2.25) at the end is that so it has a bit of back pressure?
Huge props for going to all that effort. Turned out real nice. I'd get sick of trying to make them all equal length and give up if I were to try something like that.
One thing I stumbled upon the other day. You can make the runners equal length but it doesn't mean they flow the same due to having different bends in each of the pipes at different points distances from the port, right? Would extractor design be better off trying to get each of the pipes to flow the same CFM instead of having the same length?
Not trying to rain on your parade or anything, just something I came across in a book the other day. Am I overthinking it?
Haha thanks guys. And yeah Skylar, i probably would have given up on trying to make them equal length, but because the mate i had over at the time has as bad OCD as me, he wouldn't let me haha. That worked out well for me i guess
And yeah, you are indeed correct - but because (in my case) i used a similar number of the same bends for each runner, they end up pretty close - as far as my brain told me, the real way to know if the *lengths* are the same, is to CC each tube. Because i welded each of the runners off the the flange/collector, i could do this, and the result were pretty similar (within 20cc or so of each other) - but this wasn't exactly easy or perfect, as you have to refill the burette many times to fill up one runner, which leaves a margin for error.
To be honest though, there are SO many variables that come into making a perfect header, that i'm not educated enough to even go into any more detail
Sorry if any of the above doesn't make sense, i am faaaarked.
looks really good mate, have you thought about just chucking them on a 20v and seeing if they dont leak or crack or whatever?
possibly chuck them on a car on the dyno for shits and giggles? (it should only take about 30mins to swap them over on a already converted car)
the speed of the resonance waves should be fairly constant regardless of the bend radii. If the length is the same and the pipe diameters are the same then it should work out exactly right.
