....possibly
I've been in contact with a couple fab shops
928motorsports.com
and
supechargerrebuilds.com
Both fab high-boost impellers in-house for all the other designs.
They are both willing see if one of their aftermarket impellers can be modified to fit our SN cases and/or copy an existing design. But I have a few questions:
Does anybody have a VR-4 kit they're willing to send in to be copied?
Does anybody know if there's any copyrights on the VR-4 design?
I noticed the thin aluminum vein seperating the beginning of the volute from the end, is that the reason for a new back-plate vs. a spacer ring of some sort? (that qestion's from me, not them) Edit: nevermind, I see the intake is actually larger on the VR-4 kit also.
Since this is all trial-and-error, does anybody have any input on how much psi the stock housing could develop with a trick impeller? I ask this simply because it would be cheaper and easier if we could just drop-in a state-of-the-art impeller and skip the housing change.
And how many people are still interested in picking up something? I'm sure a posting on ebay would develop a new following for this old horse- but some commitment might get a better price/faster return rate for starters.
What are people willing to pay for a new, untried design?
