are there any turbo or super charger kits for the magnas if not are there any place that would happily develop a turbo or super charger kit for a magna

Sprintex Superchargers

Meh

another newbie with lots of questions.....
rpw, or sprintex....
or just got a custom like me

Meh - do you have any details on who, how much etc for custom job?

IIRC you went a CAPA/centrifugal supercharger didn't you?

heath-ive been quoted a fair few different prices, $12 000 (twin or single), $7500, (single)
mines costing me around $10 000 all up but im not goin to one specific place

Ah - fair enough. From this I would assume this is turbocharger rather than superchargers (twin superchargers would be nuts :nuts: )

I cannot believe the price it costs to throw a supercharger on a Magna.

Thinking about throwing an M90 out of a supercharged VT in between the heads - on a custom manifold. Prefer this over turbo because...

Sealed for life lubrication system (no oil lines yay)
No tricky (hot) exhaust work
No water cooling lines (yay)

Only issue is how to run the belts (safely) and bonnet clearance... Also probably reinforcing the mounts, and adding a piggyback computer (for more fuel) and water/methanol injection to avoid preignition. (Don't like the idea of running extra injectors, seems like a bandaid solution to me) - Fuel is meant to burn, not cool the intake charge.

Doing most of the labour myself would mean it would probably cost in the region of $3000 - not bad, especially if I didn't go overboard with the boost levels...

Heath the custom intake you will require will take a bit of work (Sprintex spent a bit of money developing their one) or you can always add a nice big bonnet buldge lol . But I like your reasoning in going with this approch. Please keep us informed with any progress :D

The custom manifold is going to be the issue.

The design I was looking at doing is probably going to suck for low end torque (very short as in almost non-existent runners), but would basically follow the same sort of design as the VT manifold - that is, the under the supercharger you have a very small 'plenum' with runners being from the 'plenum' to the cyls - the magna is great for this type of design, the injectors are mounted into a seperate part of the intake manifold (which makes a custom manifold a $hitload easier to design and build, no worries about fuel pooling etc. Fantastic.

Think inverted pyramid for the design. The tail of the VT supercharger is designed to take a throttle body easily (and a 65mm one to boot) mounted at a 45 degree (roughly) angle.

Got to work out the gear sizes too...

Yeah I know what you mean with the short runner length. While this will ultimatelly effect the torque/power curve by reducing the effeciency of the engine at lower revs, it will obviouslly not be of great conciquence in this application. I'm sure the torque curve will still be greattly beefed up accross the rev range.

If I had some basic dimentions (on a simple drawaing depicting the valley between cylinder banks) I could try draw up some intake variation to see what is possible.

As you mentioned having a plenum will be important to help even out the cylider fill. I might play around with a few scetches when I get time :P

Heck yes - you wouldn't run these without a plenum, but the VT's go close - there is very little volume to play with (I wouldn't have designed them this way but meh)

I would try to get as much volume as possible to get an even fill - manifold would be made of 5mm aluminium, welded, with the tip of the upside-down 'pyramid' being bolted on to where the stock intake manifold fits (with a gasket of course, and portmatching yada yada), with the access being where the supercharger bolts on - the M90's have top mounted bolt lugs.

My main problems will be - getting a belt safely to the snout, dealing with the throttlebody being closer to the middle of the engine (throttle cable length, piping to MAF - although a totally custom CAI may be of use here) Emissions friendliness is also an issue - not sure how the hell to mount the EGR valve.

More info on how the bypass valve works would be good too - I get the feeling that it is vacuum operated, so the SC is bypassed in cruise situations, and closes as you approach 0 vacuum (under load)?

Also of concern is the mounting strength of the studs used for the standard manifold. Not sure if Sprintex / RPW design strengthens these with extra bracing on the manifold or not. Don't want to rip off the studs!

You could use the Holden gasket to make up a CNC milled top plate, (for the SC) and the standard Magna intake manifold gasket for the bottom plate - then just make some sides, with as much volume as possible. Giving clearance to the injectors etc of course.

I don't think that the standard engine covers would fit over this, maybe possible though... A nice black understated supercharger would sure look nice :)

I should scan in some of my sketches (or redraw them in *cough* word).

Well you pretty much have it all planned out. I didn't even think of th eEGR (as I don't have one, 3.0). Yeah the pyramid idea would be the easiest with this type of charger, seeing as you are incorperating the lower half of the standard intake.

If you can be bothered scanning you scetches post them up or PM for an e-mail, I'd love to see them. I'm not planning on supercharging or anything I just have a thing with intakes :redface:

If I find them, I'll post up some scetches for a varible length intake manifolds I had in mind for a magna :D
