Just did this mock up using GM's engine dyno chart and the Voodoo dyno chart that someone took a picture of. Numbers aren't perfect and are an estimate in some areas but should be pretty close.
While the initial numbers of the Voodoo look pretty good, it's the area under the curve that tell the whole story and it looks like the LS7 is a much more stout engine with the power. A lot less spiky and more predictable..

Not putting down the Z/28 and its LS7 since I almost bought one but decided on a Stingray instead and then the Z06... absolutely no complaints.
The 2 principal factors I like in the voodoo is the broad TQ curve at 3500+ and the high-rev/breathability at the upper rpm's. Plus from all the info so far it seems to be that it'll be a great track and street machine combo with excellent midrange too and it's not just a single-minded beast like the Z/28. The GT350's weight compared to the 5th gen Z/28 is another big factor... no figures yet but it's a given it'll be less. I'm already 110% sure it'll be a huge improvement over my ex-Boss 302 so that's a no brainer for me. Can't really go wrong with either cars, but for me it's the new Shelby... a better complete all-around package for my preference and moolah. |

Lastly, the gt350 makes nearly peak power well into 8,000rpms as the ford dyno release showed. In the graph listed here, it falls off far worse than it should from 7500rpm. The ls7 is great but I would like to see Chevy revise it to about 550hp. It has the potential and would help Chevy continue to command an ls7 premium. As it sits, the 455-460hp 6.2 is too close to the ls7's output to command a typical $25-40k premium. Many have argued the majority of the z28's $75k price (advertised as the cost of the vehicle) is because an ls7 is a $20k+ crate engine. I wonder what a z28 with a 460hp 6.2 would really leave on the table vs an ls7 z28. Price wise it would likely have left $15-20k in a buyers pocket.

Again great work on your part, it's just manufacturers messing with an unbroken system to advertise their own marketing points. Maybe ford wanted to show its so rev happy, I am legitimately unmoved and jaded by the choice as I wanted a legitimate dyno to look at but ford chose to leave that up to people with the desire to make a proper graph. Good work nonetheless.

If it was like 2005 where 505hp was exceptional and easily commanded a $75k price, I'd be all about the z28, but I think GM could pull 550hp+ from an ls7 revision while losing a few lbs, maybe 5-10, and bridging a gap from rivals. It's a sad truth that a scatpack challenger makes 485hp with 6.4L. Yes it's heavier and simpler but that's only a 20hp difference. What's more is dodge underrated the engine if dyno results are accurate. Many ls7's dyno 445whp with a manual transmission. Scatpack challengers have seen 440whp in manual transmission cars and 432whp (iirc) in an 8spd auto as tested by hotrod magazine. No, there is no science to comparing dyno numbers but when the numbers fall within 2-3% continuously it spells a pattern. I want the gen 6 z28 to come in around 3650lbs +/- with 505+hp and a $50-65k range much like the gt350. Let people option up to the all star, or buy the less optioned model if they want. I think the gt350 should be sold with a track and tech option though. I feel it would better warrant $60k if I could make an m4 of sorts with comforts/luxuries and speed.

There is a thread over on that other site with a poll of folks who have ordered a GT350. If you look at the numbers, it is pretty obvious that Ford's multiple option strategy is going to sell a lot of cars whereas GM's "here you go, we already decided what you want in a z/28, so give us your money" approach has made it hard to move the cars to anyone but the dedicated track jockey or people looking to add the car to a collection.
More people are optioning their GT350/GT350R's with the technology/electronics packages than without. |

So... they over produced by ~700 units. I bet they still consider it a marketing success that elevated the Camaro brand.
