So the LS9 does exist...but wait!

[Mr. Wyndham]

While I was doing some light end-of-semester homework...it occured to me:

*cloudy dream like state*

"The recent introduction of the ’08 Corvette’s 430-hp LS3 V-8, along with the release later this year of the ’08 Chevrolet Tahoe Hybrid’s 6.0L V-8, represent the last editions of the Gen IV engine family, Stephens says."

*clouds evaporate*

I mean, to be fair...we really don't know that much about the LS9. So I suppose it could be a next-gen engine.
Both of the above engines have been released, now. So this whole situation begs the question: IS the LS9 a Generation V engine? (Meaning DI) Or was this Tom Stephens guy just 'talking'...



Thoughts?

so you propose the ls9 is a hybrid motor, to be used for the camaro????

Ya know Dragon, you make a good (albeit cloudy) point. I have been STARING at the LS9 (the link that YOU posted, thank you very much) for a while now and man, it's just a piece of art! In the top view of the intercooler, I can make out what appears to be the plenum "runners" that feed the heads, and with all the fittings and sensors shown in the pics, I would expect to see some injectors in or around those runners IF it were Port Injected. DI is a whole different story.

The LS9 as I understand it is an LS3+supercharger+intercooler, and a couple other little things. But basically its an LS3. I don't see it contradicting the statement about the end of the gen IV small blocks.

ill take it if they make it!!
thats my new moto!

[CamaroSpike23]

just cus they are the last of the gen IV engines doesnt mean they cant be expounded upon. ie: LS9 = S/C LS3...lol

[Mr. Wyndham]

Good points. That whole idea of it really just being an LS3 completely slipped my mind...

kinda the whole

LS1->LS6
LS2->LS7
LS3->LS9...or would it be LS8?

[Dan]

Actually its LS3->LS8->LS9

The LS8 is a detuned LS9. I have seen articles both saying it is also intercooled and it isn't so I don't know but it is supposed to be in the 550 HP area. I don't think an LS9 will ever be in a Camaro but I could see an LS8 in one as some kind of special edition, 100th anniversary of Chevy (2011), etc.

[Mr. Wyndham]

I'm just curious...how do you know that the LS8 isn't intercooled. Not being agressive or anything - just, like I said, curious.

[2010_5thgen]

so an ls8 is a detuned version of the ls9??

[Dan]

Well like I said I have seen it listed both ways for the intercooler so I don't know who is right. I would think at that power level it would have to be intercooled. The LS8 and LS9 are basically both supercharged 6.2s with different power levels. I just get the feeling that the LS9 is going to be a ZR1 only engine like the LS7 was a Z06 only engine. The LS8 is the one I would expect to see in other models.

or visa versa...This is how I see it:

Not understanding that pic. Are you saying you think the LS8 will be lower in power than the LS3?

Oh I get it, you are saying that both are derived from the LS3. I would agree with that, they are both basically SC LS3s. Whether they created the LS9 first and made a lower powered LS8 for other models or the LS8 came first (after the LS3) I have no idea.
