Lovely job....seems a shame to hide it under a bonnet..can't you just leave it on the mantlepiece and call it art.
How much amperage did you use ? Where did you use 2.4mm filler ? (pipe to flange i suppose ?) What diameter electrode ? 304L or 316L ?
I am about to try and do something similar to yours for my alfa romeo. I am on the Designers Board at the moment !
Well its a dry band saw, but this collector is from pvc pipe !
I have my jig ready (from a previous log style manifold, talked about in older posts) but i am trying to find how pipe bends and collector will go in place without wasting precious stainless...
Small budget yes.
So, you didnt mention, What were your amperage needs on average ? Did you go on the low or on the high side ?
Awesome job, very impressive stuff.
Will be having a go on manifold for a Zx12 mini project when I get round to it.
Where do you get the bends from ?
Hope it turns out as good as yours
Lovely job there Rick - much nicer than the one I made. I'm of the opinion that equal-length runners are nowhere near as important for a turbo manifold as for a NA tuned engine, though I did design mine to keep the runners as equal as possible given the space I had. Oh to have the room you get in a car engine bay
Nicely done. Only thing i'd critique is that filler additions could be tighter/pulse frequency increased- there's some 'fish eyes'/mini craters visible
Haha, i don't think another manifold in/around the house would go down well
Yes, big filler just for around the flanges, maybe a little dab here and there, maybe if there is a small gap.
I used a 1.6mm then switched to a 2.4mm, no real reason, i was just on 1.6mm for a real tight job but switched back when i had to sharpen, as i usually use 2.4mm red bands for everything.
Collector looks ok, i'm guessing you did it on a dry job saw?
Simon's car is horrendous off the line, but it was built more to be a good all round car not drag car. It might be better this year.
I've seen that vid before. What times does that Audi do?
So you're 'pumping the pedal' rather than carrying the puddle? Can't really increase the pulse frequency if pulsing via a pedal but tightening up the filler additions/not moving as far forward between pulses will fix it. This is what i'm talking about...

With a slow pulse that freezes the puddle there's nearly always some crater defects (from fish eyes through to full on pin holes), overlapping the filler additions by at least 50% will remelt them but you need more like 70 - 80% overlap to get a smooth root profile usually
Rick ! USed 304L or 316L ? I see you used 3mm which tells me you had cracked manifolds in the past ? Really informative thread ! Thanks for sharing your work !
