How are you going to even compare this engine to the enzo's ancient V12? The Enzo's engine was first developed and built in 1996 from a derivation of the '95 ferrari f1 car, which was let's see....12 years ago. Then it was finally put into production in 2002. It is also exactly 6.0 liters, and produces >650 hp. Ferraris are track cars built with the intention of having an almost constant torque curve (albeit low compared to your beloved pushrods) and tons of high end horsepower, which creates a power surge as you accelerate.

Step on the throttle in a ZR1 and all you see is tire smoke with uncontrollable power.

You can't compare American muscle to (old) Italian finesse.

Check your facts.

The LS7 weighs 458 lbs
The new e92 M3's V8 weighs 445 lbs

My facts are dead on. The GM Performance catalog has the LS7 weigh in at 440lbs, including 30 lbs of packing material included with the crate motor. 440-30 = 410. 410 < 445.

Page 24 is the GM Crate engine quick reference guide, with the power, torque, and weight of every engine offered by GM. On top of that, the LS3 weighs a whopping 50 lbs less than the BMW plant.

I chose the Enzo motor because it was of similar output. I shoulda choose the McLaren SLR 5.5 s'charged V8. It's only SOHC but none the less its barely smaller displacement wise and makes around 620/575. So are you calling that motor unimpressive to?

Also Since the Ls9 is of the the LS family and I started with the LS1 in 1997]]>Apr 25th 2008 4:28AMhttp://www.autoblog.com/2008/04/25/officially-official-corvette-zr1-makes-638-hp-and-604-lb-ft/http://www.autoblog.com/2008/04/25/officially-official-corvette-zr1-makes-638-hp-and-604-lb-ft/
and the improvement from 617hp@6500, 575ft-lbs@3250-5000, in the higher output version, SLR 722 edition, 641hp@6500, 605ft-lbs@4000 compares favorably with the ZR1.

i am going to start using my favorite arbitrary engine stat, hp/camshaft

the ls9 makes 638hp/camshaft, ferrari needs 4 cams to get there only making 162 hp/cam. now that is what i call lazy engineering. ferrari needs to start outsourcing their engines from the same place they get their shocks!

bmw can only manage 127 hp/cam, PATHETIC! even a mustang gt gets 150 hp/cam. get your act together europe and japan. you have a lot of catching up to do.

but seriously, i swear you guys would keep bitching about hp/liter even if GM found a way to fit 10 liters and 800 hp in something the size of a shoebox that weighed 100 lbs and got 40 mpg. get over hp/liter and look at the numbers that actually affect the performance of an automobile and you will see why the chevy small block is the most successful performance engine in history.]]>Apr 25th 2008 1:11PM
