Trial fitting an LSA supercharger to an LS1

[ArnieVXR]

Minutes later and I've successfully fitted it to my VT2...



Very minor bonnet clearance issue (ahem)


So, power bulge, cutout or fit it into something with more clearance (VXR8, Camaro, Chevy pickup)?

Will it fit the Zafira?

I like your thinking

[ArnieVXR]

I imagine even the LS9 lid would struggle to clear the underside of the bonnet. The enormous lid is down to the sheer size of the chargecooler. Makes you appreciate just how much more effective these reversed PD blowers must be at keeping IATs down.

Although the LS9 obviously fits under/though the bonnet of the Corvette?

The LS9 runs a dry sump, and probably sits a lot lower?

I've been trying to source a cheap LS9 lid to find out. No joy so far.

Dropping the engine isnt always an easy task. It's bolted to the bellhousing, and in a vette that's bolted to a torque tube which is bolted solid to the rear transaxle.

So if you move one part...ie the engine, it will have knock on effects elsewhere. I dont think there is much room to lower the engine in most cars anyway due to crossmembers, steering racks etc.

And some dry sump's can be fairly deep too. Shallower overall but the man tray and collector still has depth, usually more so than the shallow end of a typical wet sump

Quite agree. I admire what Arnie is trying, but the additional fabrication costs to make a £500 supercharger fit, will take the build costs close to the cost of a Magnussen. I'm puzzled by the talk of many being fitted to G8s in the US.

In a purpose built chassis yes, but it wouldn't in a monaro. The LS7/9 sump fouls at the rear at the stock engine height.





It's not really a conventional dry sump. The single pickup is wet sump style with a deep reservoir, only the oil is removed with a scavenge to store elsewhere. A proper multi stage dry sump would have a much lower profile.

It's unfortunate the LS7/9 are basically a rear sump engine, whereas the GTO is front sump. If that wasn't the case installation would be easy, but it still wouldn't sit much lower.

This might well work, but doesn't have the nice gaskets, oval oil ports and solid construction of the original. Also needs a remote filter, but that may be a good thing.

Any updates on this? Did you figure out adapter plates?

[ArnieVXR]

I've been drawing up a list of supporting parts. The complete front accessory and pulley set from Jegs looks good value and there are plenty of new water pumps on ebay.com. Aftermarket crank pullies of various sizes are easy to come by too. I can't find any aftermarket fuel rails, so I'm after the following parts: http://parts.nalleygmc.com/showAssembly.aspx?ukey_...

I haven't done anything with the LS1/LS3 plates, as I've been preparing for the 2015 season at York Raceway (anyone have a cheap 5-tonne recovery truck?). I need to pull my finger out on this...

Thanks for this. Its also my problem at the moment. i.e fitting a heartbeat to cathedral port heads.

When you look how crap the flow paths are inside the blower and base...I really wouldnt worry at all about port mismatch as long as you can bolt it up and make it seal.

It'll still work

Problem will be turbulence even with boost. You cant just sit a big lip in the flow path without extra penalty.

Again, look at the flow paths inside the blower itself, they're terrible but they still work.

And turbulence can be a good thing
