I know its not for sale and probably won't be, but I would say 1500$ for a one off piece like that is more than a bargin. Remember, when someone is buying something thats low production or handmade, you're not paying as much for the product as you are for the knowledge, as obviously, not many people can build things like that.

That's Schnobbin' !! ... one question though Warren. Would putting a couple of slip joints in the last section of each of the legs (where you welded the 2" spacers in) ... would that simplify the turbo mounting? You wouldn't have to allow for so much heat related movement in the S/S.

The Harley dirt tracker theorists say their advantage over the parallel twins over the years was the uneven pulse of their Vtwins; they think it allows the rear wheel to hook up between pulses of power to the ground. In euro FIM grand prix mc road racing, they HAD something called the "big bang" where they had 500cc 4 cylinder bikes making 500 hp and ALL of it hitting at one instant! with 360* of rotation between power pulses! Same theory, within a single wheel rotation, a single big pulse as opposed to four little ones, allows the rubber more time to grab the pavement and hook up. Whether they got away from the big bang for other engineering reasons (vibration/blocks splitting) or not, I have not read of.

Slip joints would likely leak gas pressure, or be so tight as to render them useless. The turbo can be removed through the top left of the intake no problem..........I've read a comment about the header hitting something during hard use, not going to happen as there is ample room. I've measured about a million times............You only have to be smarted than the tubing to build these.

hahaahahaa, Good one, "smarted" hehehhe

Whats smarter now, the tubing still?

BTW, is this the only item your changing?

Don't shit up a perfectly good thread with "Lounge" antics.

The tubing is still on top!

I was thinking more about controlling the expansion of the pipe not getting the turbo out
I know you said you had that covered. ... just not how to brace the turbo. Cutting the pipe movement off near the turbo would mean you could almost solid mount the flange. You'd have to engineer a slip joint exhaust gas seal though.

That thing is crazyer than the one on my car i like it. Well you did a nice pice of art work how many days do you have in it now , I don't want to change that head gaskets on that one, just joking it won't be worth it .

Maybe this would work better than slips ... no seals to engineer.

Oh, ok I misunderstood. I have all my turbo mounting figured out, I will post pics when I have it all built. those bellows seal are interesting.

From what I understand those still break. They would end up fatiguing over time and developing stress cracks(unless they were titanium...didn't look all that well, but then you have to figure a way to secure them, ect.)

I know...screw it. Use some of that steel strapping material to make a sling to hang the thing from and hang that bad boy from the intake! t won't go anywhere then...(this is a joke BTW)

Your a moron!
I was joking around, Warren got it, why couldn't you?



Anyhow, back to our scheduled program-

What about using the slip fit and using springs like we do on our Motorbikes. We use Titanium systems and they don't leak. There mounted solidly and don't snap or fatique crack?
