Does onyone know if these are 2 completely different engines and if not what is it that makes the LS9 so F****ng awsome?

CamaroSkooter · 06-15-2010, 05:10 PM

As far as I'm aware, more of the internal components are beefed up in the LS9 and the supercharger is bigger...

2SSARMY · 06-15-2010, 05:16 PM

LS9 is a stronger engine.

Lucky SOB · 06-15-2010, 05:30 PM

Well it makes what, 70 more HP? I'm going guess it's a bunch of different things... heads, cam, stronger/forged rods, pistons, intake.

wylde1 · 06-15-2010, 05:30 PM

LS9 - forged internals (crank, rods), Supercharger is 2.3L

LSA - cast internals, Supercharger is 1.9L, and slightly less static compression ratio I hear (around 9:1, LS9 is slightly over 9)

I believe their intercoolers are slightly different as well. Different compression suggests different heads because I think the block and bore/stroke are "shared". And with a different supercharger, you're probably lookin' at different cam and intake as well.

EDIT: just found this too

LSA Cam specs

Valve Lift .480" intake / .480" exhaust

Duration(@.050 in) 198 intake / 216 exhaust

LS9 Cam specs

Valve Lift .562" intake / .558" exhaust

Duration(@.050 in) 211 intake / 230 exhaust

For interest sake haha

LS3 spec
http://www.gmperformanceparts.com/En...1992&engCat=ls

looks like you throw in a forged crank and a super charger and the LS3 would be on top of the LSA. On paper anyway

mcrizz · 06-16-2010, 01:35 PM

Very good info thank you.

halo8hkk · 03-29-2012, 07:10 PM

Wow that's a tiny cam in the LSA. I thought there would be more lift than that.

fourmz · 03-29-2012, 07:12 PM

Also , I believe the LS9 is a dry sump whereas the LSA is a wet sump. I could be wrong though.

Cpanthers85 · 03-29-2012, 11:35 PM

Holy revive old thread batman!

The LS9 is dry sump. It also has forged crank and rods, a different cam and valves/valve springs, oil cooled pistons, and a bigger supercharger.

I'm taking my L99 and converting it to a mock LS9. LS9 cam and valve train and then in using the Edelbrock SC
