My first ram horn
I have been working on this manifold for a while now (too long) for a friend and so far it seems to be turning out ok. I have been building this with a very antiquated saw. This so far has seemed to be my biggest issue. I had someone custom cut the collector for me. Each runner was cut 5" long and at two 15 degree angles. This manifold was originally going to be a miniram but because of the really long runners would not work. (runner length has been noted in my branium for future manifolds) I attempted to cut them shorter after I had already welded them but it was to late to try to get the collector any shorter. Hopefully these issues will be solved once I pick up my new saw (complements of the guy that couldn't turn into a parking lot).
The next hard part about this manifold is the fact that I am human. These being the case, I only have two arms, and attached to those two arms are only one hand per arm. Simple math, I need more hands. Trying to make the pieces all fit together, now with a slight lack of symmetry I might add which you can see in the top view of the collector has proven to be challangeing. I have managed to shuffle everything into a way that will work out pretty well I think, but over all, this usually would not pass my anillity standards, although I am cutting myself a little slack as this is my first. (That last sentance had a lot of commas(I suck at english)) I have a few small pieces left that I need to tack together to make sure everything fits, then I will be breaking it all down and finish welding it, but for now, here it stands.

Re: My first ram horn
it looks ok for your first one, but you need to spend more time making the collector square, so that when you start adding runners to it, they all come off at the same angles. if you don't do this, it looks funny.
a little hint to help you square it up. tack the collector to the turbo flange, then start building a runner i start with 1 or 4. Then measure from the turbo flange to the head flange. this will get you very close, then you need to watch so it is square. so if you were to set it on a table the head flange would sit straight up and down.
This way i can make ramhorns on my bench with out even using a motor.
also i use a 4.5" collector on my ramhorns, this allows you to fit the collector and trim the excess off to fit.

Re: My first ram horn
Yeah, the other issue with the collector to is that I cut it with a wood chop saw with a carbide blad on it so the cuts on the collector ends where the runner meets are not square either. I am going to be picking up a horizontal bandsaw from grizzly in the next week or too once my insurance money gets here. Should help me get a lot better cuts. Thanks for the suggestions by the way.
