That's GT500 and 911 Turbo S territory - with an NA engine.

Carwow got a 10.1 out of the 911 Turbo S!

I don't know exactly who the dude is. But there was some dude on a ZL1 page talking about how potent the Voodoo engine is. Come to find out his GT350 had been in the shop for almost a year. I asked him how much he had into it and made a guesstimate of around $20K and he said it was much more. Another shop had a GT350 that they pushed to like 800+ RWHP. A few people commented on it that they were concerned if it would last. It most certainly did not last. The engine blew up. It is not a wise investment to say the least. But to each their own.

However you want to say it is not important. The point I'm making is that there are a few options but it would be nice if one could get a more power trim without having to step up to the ZR1. In the C7s, it would have been nice if they did a reverse of the GS. Like maybe the C7 Z06 engine on the Z51. That way you have a car that still handles decent, you're not spending Z06 money, and you get the power. Some people love the handling and that is cool. But I think more people would have opted to have that 650 HP instead.

That's GT500 and 911 Turbo S territory - with an NA engine.

A few weeks ago I watched the Lamborghini Aventador review by Throttle House on Youtube. The Aventador was 759 NA hp which runs 10.5 @ 136 mph (C&D). A comment stuck with me from that video. They said they had just recently reviewed the GT500, which at 760 FI hp has broken well into the 10s on many occasions on stock tires, and hit 132+mph trap speed. They have about the same amount of power, but the reviewer said that the Aventador felt like it had 1000 more hp than the GT500. While the Lambo is obviously quicker (and $400k+), it is NA and felt much quicker to the driver than the GT500 did, even though they are only a few mph different in trap speed and have very similar lbs/hp ratio (5.2 vs. 5.3). The GT500 is ~200 lbs heavier than the Lambo, which helps partially explain the lower trap speed (and likely aerodynamics is the other part), but you'd think the difference would be slight, not drastic. Anyway, it was an interesting comment because I've always thought that most people thought forced induction engines feel quicker than similarly powered NA engines because of the torque. I realize this is comparing a Lambo to a Shelby, but I brought this up because they have nearly the exact same rated hp, and similar lbs/hp ratios, yet the amazing NA engine in the Lambo feels much quicker than the Predator.

Personally, I like high hp NA engines. Getting a car to go fast with boost is one thing, but getting similar trap speeds NA is on a different level. i.e., Huracan Performante (traps 136 mph), Ferrari 812 Superfast (138 mph), Aventador (136 mph), GT3 RS (129 mph), I'd even throw the C6 Z06 in there given C&D was able to trap 127.1 mph with a 2006. High hp NA engines are a dying breed; I'd love to see a 625+ hp NA C8 Z06.

Like a Stingray with a Super charged LT2 plus forged internals etc.....like an LT4 is essentially. I can't see why not!

Just in name only. The E-Ray is basically the Grand Sport.

Get past the nameplates and it's basically everything that the rumored GS was supposed to be.

Anyways, who cares, it's going to weigh a ton with the battery and electric motors. I care more about what the specs of the Z06 are going to be. That IMO will be the Goldilocks C8 version.

Oh, wow. Yeah, the new 911 Turbo S w/ 640 hp is very quick. I won't be surprised if it does 0-60 in 2.2 seconds when it's finally tested by C&D or MT. Of course, those AWD cars are helped immensely by the 1 ft rollout stat the magazines use because they launch so hard out of the hole they're going 5-6 mph in that first foot, so those quick 0-60 times are really actually like 6-60 times. Compared to a front engined RWD car that is probably only going 2-3 mph after 1 foot.

Anyway, I should have clarified - I meant the 580 hp 991 version Turbo S, per MotorTrend:
Our track results can vouch for the newfound potency and response. It reaches 60 mph in 2.5 seconds (reading that sentence aloud takes 2.5 seconds). It does the 0-100 run in six flat (not bad for a flat-six), and blasts from 0 to 100 mph and back in 9.7 seconds. It almost makes the Porsche's 10.5-second, 131.8-mph quarter-mile time anticlimactic.

Roll out is comes into play on a timed 1/4 mile track. Its the time it takes for the front tire to roll out of the beam to start the clock. Roll out is worth .1 to .2 reduction in ET. A car that runs a true 11.0 for instance will ET at least 10.9 . Thats why you stage as shallow as you can to increase roll out. ET is the only important factor, not MPH. Some Magazines show at .2 lower ET and note that is figured with the 1 foot roll out factor just to show and sell hype of low ETs

Agreed with everything said here. If the goal is achievable through an NA application, that is preferable imo.

The c6 z06 is a good old school and "low dollar" example of this.

Look at how capable the McLaren F1 was an NA car too.

The new 911 Turbo S is just an animal and a big jump over the previous car.

Yea GM's r and d was taking place on the race track not through the customers at their expense.

But I think more people would have opted to have that 650 HP instead.

The gt350s motor is stout up to around 800rwhp and there are plenty of anecdotal examples that support that. Gt350 reliability is a crap shoot stock or modified though, but what I'd really worry about when making anything much past stock power is that trans going any second.

Wording may not matter to you but it does matter. GS shares the powerplant with the z51, it shares literally everything else with the z06. More than just dress up.

While some might like the idea, I don't think GM would ever stick a 650 or 755hp engine in a chassis that isn't really set up to handle the power. They usually build complete sports cars but I get what you are saying. Same as the guys that want an LT1 trim style Camaro with an lt5 in it.

yep, my second motor didn't get a whipple because mcleod was having major issues and the transmission was iffy on handling the torque. those motors just seem to randomly go south whether stock or modified like mad. can't deny there's a bunch of them making huge power now and doing it successfully.

Yea it seems to be the luck of the draw with voodoos, though you could say that about a lot of engines the voodoo's are obviously more susceptible to random catastrophic issues than any other current American v8.

Non the less there are examples of some kicking strong. I would say if you are going to mod, be prepared to pay the price of things going wrong. Really that's with any modded car, but with the voodoos history and associated costs it is much more of a concern.
