Supercharger brackets....
Discussion
Long shot I know but does anyone have a Rotrex supercharger bracket for a Rover V8 that isn't in use at this precise moment or that I could get measurements from?
I've mailed SC Power but although they're happy to sell their kit they've not replied to my request about buying the bracket from them, similarly Phil Ringwood has one that he built himself but hasn't got round to building any more of and won't do for a while.
In that case would like to see how difficult it would be to make one...

I looked into this in quite some detail before settling on the turbo route and seem to remember there was something quite trick about the SCP bracket in that it allowed for expansion/contraction through heat cycling, which was apparently necessary due to the mounting points it picked up - if so, that implies considerable development was undertaken so imagine that might be why they are not separately available as it really is the key to the 'kit'.
It's quite some time ago now but Mike J (Boosted LS1 on here) did mention to me that he had one he had made that was surplus so maybe worth a ping. You've probably twigged already there are big differences between the power steering and non-PS cars in packaging a rotary blower... again, when researching, it seemed a no-brainer to get rid of the hydraulic PS set up and go electric to make room and avoid having to completely re-engineer the belt runs etc

Hmmm ... I'd be very surprised if thermal expansion due to heating and cooling was significant enough to make that much of a difference even in a TVR engine bay. As far as I'm aware it just picks up on the power steering pump mounting locations and uses those. Of course maybe that additional special thermal engineering is why the kit costs so much?

OK - might do that - thanks.Pupp said:

Absolutely - the only reason I'm looking into supercharging is because mines a non-PAS car - I would like to go for PAS in the future at some point but would probably go for an electric pump and Scooby rack.

OK so it can't be hard to fit PAS (you are still a girl) and I'd reckon an auto box (were they Borg Warner?) would fit the Chimaera.
Hoping it won't come to that but that could be the worse case scenario...Mark. said:
Come on bruv, you waited so long to get in one, got to keep you there now!
Oh believe me - you'll see me buried in a Blackpool bucket... I don't expect you'll get anything out of SC Power. They did spend a considerable amount of time and money developing the kit, and the price is set so they can recoup that money over time. If you want to use their design then really its only fair that you chip in for the development...

No idea, I'm neither an engineer nor a materials specialist so was quite happy to take the word for it of the guy who developed the thing. It was more to do with avoiding head gasket problems than anything as I recall, which suggests the deck is bridged. If you have the blower to hand , just offer it up and get measuring; after all, how hard can it be and what can possibly go wrong?

Yup - hence why I've asked them if they can sell me a bracket ... I don't expect them to give me one for free.It would be really handy if I could buy one from them because then that would mean I don't have to get one built for me ... and of course if I don't have to get one built for me then I won't be tempted to run off a few more for other people that might be interested.
Remember that it becomes reasonably practical to get castings made up nowadays when you have access to 3D printers and CAD software.

That's why they only sell the whole kit, not just bits of it.
Like Nick says SC-Power invested a lot of time designing everything, & (as you have discovered) the bracket is one of the key components & challenges to putting a readily available off the shelf supercharger on a Chimaera.
As such to SC-Power that bracket carries value way beyond it's material or manufacturing costs.
If you had made the same investment in time & effort I doubt you'd would want to sell just the bracket either, only to see it get copied.
Selling just the bracket is not exactly going to help SC-Power improve their supercharger kit sales, quite the reverse, once the CAD drawing is in general circulation demand for the SC-Power kit will vanish overnight.
And lets face it if you're one of their customers who's invested a lot of money in the whole SC Power kit you're unlikely let someone else borrow your bracket so they can copy it, only to watch them build themselves a supercharger kit for a lot less than you had to pay.
Personally, knowing all this from the outset, I wouldn't even have had the balls to ask SC-Power to sell me just the bracket.
It pretty obvious what their answer was going to be, TBH if it was me in their shoes I'd be tempted to be quite curt in my response to such a request.
The solution of course is to replicate all their design work yourself & create your own bracket, after all the initial investment in time & energy you could sell your bracket as a little business opportunity.
Until that is someone copied it
