A few of my customers have dynoed their bone stock C6 Z06 and they are making 455-460 RWHP..so GM is real conservitive on the 505 FWHP..looks like they are making about 535 FWHP give or take a little at the crank.
Doesn't an M6 C5 usually drop about 40 - 45 HP from the crank to the rear wheels??
C6 shouldn't be very far from this.
Wouldn't that put the C6-Z06 closer to 505?

That is a little baby cam..the car idles a 600 RPM and has no vibration at all..can't even tell it is running..you can use the new Z06 as a around town dailey driver if you want to ..a very docile car till you put your foot in it...now on the other hand put a 254\254 .630\.630 110 LSA in it and watch what happens...that a long with a set of long tubes and a good exhaust system with a custom tune and it makes 640 + HP at the crank all day long...
I agree that the cam is small but, my car bumps around pretty good at the stop light. You can definitely hear the cam. I've had many people comment about the sound. I have the LG long tubes with an exhaust switch. I'm sure that helps a little. Even when it was stock (2 weeks ago) you could hear and feel the cam.
The car pulls like a jet airplane taking off in every gear.

No, because drivetrain lose is a %, not definite rwhp number.

I'd think about that for awhile
You're saying that as I increase the HP of an engine (mod it ), at the flywheel, the parasitic losses increase also??

The loss from the flywheel to the rear wheels is usually in the 12 % to 15 % range. If you use a 15% loss from the flywheel to the rear wheels my math is correct...15% of 535 is 80..now subtract that from 535 and you have 455...so the LS 7 is making around 535-540 FWHP to be putting 455-460 to the the rear wheels.

Your math is correct.
But you cannot base your computations on a loosely held estimate of RWHP. The drivetrain losses of these cars are known.
The losses do not increase just because the HP does- for a given vehicle.
I doubt the C6 losses exceed the C5 by much if at all.

Ok here is one for ya..Hot Rod Magazine just did a dyno test on a LS7 crate motor and it made 540 HP at the flywheel..what a coincedense...

Kinda OT, but could you put this cam in a LS1 and get any power gains? Thanks.
If you are going to the trouble of doing a cam swap do a REAL cam swap

What the LS7 puts down (or out) isn't the point. The failed assumption that you can reverse calculate 10 - 15% of any HP rating is the point.

STOCK LS7 CAMS INTAKE EVENT CLOSES LATER THAN A LOT OF BIGGER (233 duration@.050) CAMS.

a few questions Bill, if u dont mind
can this cam be used in a conventional
ls1 engine?
does it have the reluctor ring at the rear of cam?
is the LS2 timing sprocket and front sensor needed to run this cam
in a ls1 with the stock sensor in the "distributor hole"
i am intersted in the cam because i understand its under
200$
looks good for a budget FI cam
What affect does the huge difference between the intake and exhaust duration have on performance? I am wondering if I can use my 224/224 as a smog cam for my new motor.

Sorry, but Bink is wrong the losses are proportional to load. If you jacked the rear end off the ground, replaced one wheel with a crank handle and held the clutch down (or to be totally accurate, removed the friction disc) with the tranny in 1st, your could probaly spin the input shaft up to over 1,000 RPM with your puny 1.0 AP (Arm Power), and the limiting factor would likely be how fast you could move your hand, not the load resistance. The friction losses in a bearing or a gear pair are very much proportional to the load they are carrying. This isn't to say the losses are a guaranteed, set-in-stone fixed %, but they are definitely proportional to speed and load.

Try reading the article in HOT ROD..the dyno test on the stock LS7 crate motor with stock exhaust manifolds no cats no mufflers produced 546 FWHP..knock off 20 or so for the no cats and no mufflers and you are at the number I posted..that is the point ! ... I said that these motors were way under rated and the are..happy phuchin new year

Wow, the thumbnail Gollum posted shows a Stage 3 cam w/ .050" numbers of 233 intake vs. 276 exhaust, I have never seen such a huge split before. I guess the exhaust side is really compromised to allow for the largest possible intake valve and angle.
