Nathan, do you know if there have been any issues with the SC12 clearing the hydro mounting plate off the firewall.......?

Was looking yesterday and thought it may have to be moved to the right (looking at the bay from in front) to gain the necessary clearance?

O no... Steve is getting ideas

Sssssshhhhhhh dammit

Hmm... good question there Steve..... I think clearance will definately be an issue for 2 reasons....

1- the new thermo-stabiliser bar uses the 2 subframe tower bolts as the mounting for the body bracket. This bracket will definately need modifying to allow the hydro line to pass thru it (between the subframe tower bolts). I would say you will need to fabricate a different bracket here.....

2- The supercharger will most likely be exactly above where the hydro/body bracket is fixed.... which will not allow room for the hydro line to come up above the bulkhead crossmember........ see pics below..





You should be able to work things out from those 2 pics.... I would say "hydro + SC = not gonna happen". Maybe time for a dry spring conversion.

hmmmmmmmmmmmmmmm another boggle to add to the massive list that i already have

I disagree........only because I'm stubborn.

Extending the undercar pipe on that side should allow for relocating the bracket slightly sideways or higher for mounting the connection to the hydro hose.

And like you say, a new bracket would have to be fabbed for the other mounting point where the house exits the firewall crossmember.....not impossible.

I sent 92 a PM yesterday or the day before and im just wondring is he still doing the kits or not anymore.
I really want to buy one when im over there to put on my motor when i get back.

Yeah, I didnt think of that before, but it came to mind today..... but you beat me to it.....

The steel line would need to come up alongside the radiator... between the rad and the bulkhead.... its the only open spot that is close by....

So yes, it IS possible.... but still not 100% straight forward.

I didn't really design these with hydro suspension in mind
and yes the steel pipe could be bent to the radiator side about 70mm and it would clear the blower pulley and the new engine steady could have a hole cut in it big enough for the displacer unit hose to run through so it all can be got around but as SC 850 said not a straight fit

Hey guys... forced induction seems like the cheapest bang for buck in the search for power. And as soon as my bank balance recovers from some recent spending sprees I will be searching for power.

If I were to put a SC12 supercharger on my engine how would I lower the compression to a level that would make it work? At the moment the head has had a fair bit of work done and it's currently running at 9.5:1 compression. What compression ratio would be recommended or does it all depend on the level of boost?

7.5:1 would be ideal.
Can be done through enlarging the chambers on the head.

My SC12 Supercharger is still for sale, if you havent already found one.
$250 i am asking.

I've been warned against listening to you willy... can anyone else answer my questions?

Stocko compression, about 8.5-8.8:1 is about ideal. (But not with standard pistons, use forgies) This is what most new turbo cars are running. It gives you a little more oomph down low, but not too high so as to hinder the boost. I know this is the case with Turbos, but with S/C type boost? Not sure.

Maybe 92 or SC 850 can help? These two maniacs have been playing with forced induction waaaaay longer than me.

I have an 1100cc sligtley modified motor, custom needle, headers/extractors, rebuilt/reco engine, new gear box, 1.5 inch SU, can this sUpa charger work - is my engine compatible?

You can go about it a few ways..

You may be able to take alot more out of your head, but seeing as it's already ported, chances care that it's been skimmed a bit though too..less room to play with.

This means either getting dished/deeper dished pistons and/or using a new head if required..

If your going to supercharge it, I would rebuild the bottom end first..unless you just want to strap it on and blow it up..then build it properly for the charger

9.5CR is too high to get away with...you want a max of 8.5:1 at minimal boost..4-6psi...lower if you want to run more..

From what i've read anyway..i'm no forced induction expert either..
