there is only one belt length that is 13.9, the rest are 14MM, also 13.9 is a htd tooth profile, there are HTD and GT profiles in 14 MM
the Boost is better, but the real benefit to the LB-20 is lower manifold temp, less parasitic loss, more consistency from run to run , and...
Cost of a rebuild runs about $350, That's restrip, seals, check timing, gaskets, etc How often, depends on what you are trying to achieve
If you do put a divider in, in needs to be .060-.080 from the rotors, the divider helps the air from spinning like a tornado in the injector,...
It would be interesting to see the outlet temps between those two blowers and the parasitic loss comparison, because that has a lot to do with the HP
if I'm not mistaken, waterman has a shop in Indy and in charlotte,
the blowers made today from "most" of the manufacturers are more efficient than they were about 5 yrs ago. In blowers there is "parasitic...
To clarify, we are not having them made by fowler, we have a complete new and different person doing them for us
We knew this was happening long before, and were already getting new ones made before it changed hands, i believe the new ones are better than...
Jeff fowler bought the Kobelco supercharger operation, tooling, blueprints and everything that went with it,
I'll check the book mon morning and let you know
Being anodized or polished wouldn't matter about the rotors, call whichever mfg built the blower, most blowers have a serial # and that tells what...
What you want to do does work, the divider needs to be about .060 from the rotors, there is a lot of harmonics with the divider plates because of...
As I heard recently, throw $100,000 into a fire, if you don't flinch, your ready to build a race car
Like mikesaid call Darren, I can't do it our shafts are different
Two ways to look at it, actual cost of going down the track without hurting parts, or, total costs of the operation divided by runs made for the...
turn rotor about 800-1000 rpm, feed the tool slow as possible, take a rough cut about .030 bigger than final cut, there should be a number stamped...
I set them up with .002 on the bottom, they will have 007-008 on the sides,from rotor to case, the Teflon wear is more critical than the nylatron,...
you could most likely slow your overdrive down about 10%, be pretty close with your tune up and get the ET your looking for
the 16-71 is a high helix you have with a delta bottom is most likely a high helix, the only reason we can't make a 16-71 LB-20 is the case...
