Upcoming LS engines

http://www.leftlanenews.com/a-detail...tor-plans.html

Interesting stuff, dunno how much of this is really true though.

Quote:

LS7

This is, of course, the current 7.0-liter, naturally aspirated motor in the Z06. It's handbuilt at GM's Wixom performance center and is very expensive to make. Too expensive with the LS9 motor coming. While there will be several months where the LS7 and LS9 will be built at Wixom, the LS7 will eventually die, probably sometime between late-2009 or mid-2010.

Several publications have repeatedly insisted the new CTS-V will be powered by the LS7, but this is completely false. GM cannot spend engineering dollars on a CTS-V to start with the LS7, then 12 to 18 months later, switch motors after the LS7 is discontinued. Rather, the super Caddy will feature an all-new powerplant.

LSA

The LSA will find its way under the hood of the 2009 Cadillac CTS-V. The LSA is a 6.2-liter, smallblock V8 with a supercharger. It features an intercooler integrated into the intake manifold.

Preliminary specs have it over 500 horsepower with a choice of manual or automatic transmissions. The CTS-V will start production in September of 2008 with this motor. Look for around 6000 to 8000 units annually.

Original plans also had the LSA going into an Escalade V-series truck. However justifying the development cost — not to mention CAFE considerations — might put possibility of such a truck in jeporady. At present, it is unclear whether the Escalade-V a truck is still part of the plan.

LS8

This is another 6.2-liter, smallblock V8 with a supercharger. It also features an intercooler integrated into the intake manifold. This will be the motor going into the top-end Zeta platform cars. The most premium Camaro, probably called Z28, will get this motor.

That said, original plans had this motor going into a Denali SUV or truck, however, those plans now seem to be canceled. Again, this maybe a result of CAFE.

Some of Holden's vehicles may also get this motor eventually. Initial specs have this motor at 475 to 500 horsepower with a choice of manual or automatic transmissions.

When the LS7 dies, the Z06 will get this motor. Possibly, slightly uptuned from the version the Zeta cars would get. This motor will start production in first or second quarter of 2010.

LST

Yet another 6.2-liter, smallblock V8 with a supercharger. It also features an intercooler integrated into the intake manifold. This motor may or may not still be in GM's plans. The original plan was to put it in GM's Heavy Duty trucks.

Delivering in excess of 450 pound-feet of torque, it was set to start in the middle of 2008. However, it now seems this motor may no longer be part of the plan. GM may have decided its diesel offerings were sufficient. It's also possible GM had a hard time justifying the cost of development. Of course, CAFE might have also played a role.

LS9

This is the 6.2-liter, smallblock V8 with a supercharger going into the ZR-1 Corvette. Like all the others, it has an intercooler integrated into the intake manifold. Original specs had this motor at 600 horsepower and 550 to 560 pound-feet of torque. It now seems the horsepower rating may have jumped to as much as 650.

If that's true, it would probably be safe to estimate a similar jump in torque to around 600 ft lbs. Sources have stated the LS9 can make 700hp on a test stand. Obviously though, that is without a car attached to the motor. Don't look for any production hp number starting with "seven."

It now appears an auto/paddle shift may also be an option on the ZR-1. This motor will be handbuilt at GM's Wixom performance center. They will only make 1500 to 2000 units a year. Production of the ZR-1 starts in July of 2008.

they said the most premium camaro will be the Z28?? i thought the most "premium" camaro was/is the SS??

They going backwards?

:drool::drool::drool::drool::drool:
which one to get for my T/A?????

I still say 'back in the day' the Z28 was the premier Camaro....

I cant wait for this car. I will order one! Ls9 motor around 600hp is amazing! Im just glad its not another weird design to the motor like the original zr1. Im hoping its also priced under 70,000

Wouldn't it be cool if there was a luxury manufacturer which has plans of topping those hp #'s in the near future... and astronomical earth shattering tq??? ;)

The SS package used to be more of an appearance package, that came with some performance upgrades, while the Z28 was the "race" package. Hopefully GM will be returning to that setup :)

No way in hell. Every estimate I've seen for price has pointed to somewhere around $100,000.

Sigh - not even close - it will be WAY more expensive :(

Oh no, not gunna get into the Z28 vs SS battle....
In a nut shell, SS was a hood scoop, wheels and exhaust over Z28 for the 4th gens. Untill then Z28 was king.

The new SC 6.2's are just the begining. Remember that GM could easily make 500hp out of a direct injected 6.2, and they already have. The test mule for such engine exists as a 08 Escalade and it makes "well north of 450hp" and that is with the truck L92. The LS3, its higher performance brother, makes 40 more hp over the L92, so a 500 hp 6.2 could be easily done, and that would make more power then MB 6.2 :)

The SC motors will be great, and the LS9 is said to be DI, hence the massive power over the other SC 6.2's. We could very easily see a 650 stock ZR1 Vette, and just a simple pully and tune away from 700+.
No, it wont come under 70k, not with what they have planned.
