LS9 camshaft - what's it good for?

[ArnieVXR]

Will it work well with an LSA supercharger (TVS1900) that's going to be spun reasonably hard?

Yes it will. I have an LSA cam at home but the LS9 will wake the car up a bit. Most gained 30-40rwhp over the mild LSA cam just by doing the swap and re-map.

Will dig out the dyno graph comparison when back at my computer. Decent gains to be had at top end iirc

Bare in mind AFAIK the LS9 is a single bolt, so it's only a cheap purchase if using it with single bolt cam gear

That onthedyno page did some tests and even a relatively mild aftermarket cam did yield good gains over the LS9 cam.

So Whilst an LS9 cam would be better than other standard cams, even a mild aftermarket will allow better gains

Looks like you need to register with them to get the full info as it isnt on their site anymore.

This graph is still on their FB page though. I'm sure I remember there were other tests with different cams somewhere though.

Depends if the supercharger is attached to the engine. If it's all in a pile on the garage floor, I'd say it doesn't matter.

LS9 is better than stock but you are better off with something with a bit more exhaust lift/duration. Monkfish cam seems to work well for most. I'm very happy with my GT9 cam but it struggles with emissions.

The BTR cam faired very well in the test I linked to earlier.

Interesting that it comes as standard with the LSX376-B15. Explains why I found a new one for £110 plus vat and duties.

They are only about US$150 new from GM, but to use in a 3 bolt application you need a fitting kit which ends up making it near the price of an aftermarket cam.

Odd...Their listing says the LS9 is a 3 bolt and those wishing to use single bolt needed the fitting kit. I thought it was the other way around

One of the ADM twin turbo Camaros has run over 200mph in a mile, auto box and generally seems to be a great build and runs the LS9 cam.

Even MF seem to list them at £147 all in.

Good value upgrade if you've just a standard factory cam other than that

Can confirm the Cam is 3 bolt and as such a direct replacement in an LS2.
Still running mine. Hard to quantify benefit over stock as I've no baseline, but dyno runs show power increasing all the way to the redline at 6800 with my setup. No emissions issues as expected with an OEM cam and not too harsh on the valve train. Was lingenfelter's blower cam of choice before the GT9 arrived.

Sure a few more ponies can be made with an aftermarket cam though. Takes your choices.

I think the B15 comes with an LS7 cam. Take a look at this article: http://www.chevyhardcore.com/tech-stories/engine/1...

The cam they end up with is sort of similar to the GT9. More intake duration though weirdly.
