Sparky, who is the supplier for the silicone hose in CO. Vesco is looking for vacuum hose that is gas proof.
Thanks
Glen


Well Joey D and I  got really lucky today.  I found a web site with nothing but silicone hoses on eBay and in CO. and ordered the hoses to make this thing work.  Went to the steel place and found a 90 deg weld El that was slightly larger on one end and we to the local turbo shop, Turbos Direct and pick up a T2 flange. I used the die grinder to recess the weld El and walla -- we have exhaust plumbing we should be able to weld a tab on the curve of the 90 and bolt it to the frame. We used a cut off wheel to modify the exhaust flange and a vice, vice grips, and a ball peen hammer to fab the exhaust.

Will order the 12 volt tranfer pump from RB Racing on Monday

Oh by the way the name of our entry is BlackSmith Racin---go figure

Be carefull on silicone hoses for vaccum and pressure. There are many aftermarket companies that are offering silicone hose that are using inferior product. I would ask for some type of spec sheet. Make sure it passes SAEJ20 Class A specs.

The thing you want to look at most is operating temp of the hose, don't take salesman word for it get a spec sheet.

There are silicone hoses out there that are thick but the operating temp is only 150-175 degrees. The hotter it gets weakens the structure of the hose. And that is where the problem is.

I know of a quality silicone hose that has 300 degree sustained temps without collapse at 25"/hg .... Max temp of 400 degrees reduced performance will happen.

Enclosed applications like streamliners should be aware of this.

Question of the day: Heat Shields

I have an elementry knowledge of heat shielding and we have under way trying to build a 3 layer system with SS and alum.; three dead air spaces under the seat that air can flow through

What are some magic materials we can pad the seat with and cover the turbo with to keep Joey from having calf fries? shocked

Thanks for  the question about volume---we did some research and decided to match up with the 2" od end and not the 1.75 od end. That will give us  500cc in the tube alone not counting the volume in the head or in the turbo  so I am guessing we will be around 1.5x displacement.

Looking for sprockest today and found out the stock compression ratio is 9.2 and the stock springs float around 8200--hopefully they will handle 7-8 psi. at 7000.  Thanks to all who responded  on and off.

Type "motorcycle gearing calculator" or similar into a search engine and several will be available.  There is one on the formulas part of this website.  Assuming a reasonable top speed, 3 to 5 percent tire slip, and the rpm you will use for sustained speeds, it is possible to figure out a starting point for the sprocket combo.  Extra sprockets of different sizes are always handy.

Don't knowif this will help but on my 500 Norton I run 22/42 on the primary and 21/42 on the rear.  In fourth at 1:1 thats 3.90 overall.  On my sidecar also powered by a 500 Weslake single the gearing is 26/42 on the primary and 21/47 on the rear.  3.84 overall.  I think with a turbo you could gear a bit higher than that.  I'm taking the sidecar to Bonneville this year and am considering going to 28/42 for the primary.  3.73 overall.  Hope this might help.

Baby has new Avon shoes  will take picts this weekend.

Question of the day:

Does the reference in the rules about streamling leathers refer to the hump behind the helmet that some leathers have?

Yes, it does mean the hump in the back of the leathers, Sparky.  The hump isn't supposed to be there if you're running in a "naked" class.
