Automotive News, Media & Press - Official ZR1 Horsepower & Torque Numbers

http://www.autoblog.com/2008/04/25/officially-official-corvette-zr1-makes-638-hp-and-604-lb-ft/

Horsepower - 638
Torque - 604
And these are SAE Certified numbers!
Part i want to see is the fuel economy numbers, in the link GM expects the LS9 to be the most fuel efficient 600+HP engine in the world.

Video of ZR1 being tested by engineers at the Nurburgring! Awesome!!!**

I wonder what a tune will yield?

And then a pulley swap?

The upcoming Cadillac CTS-V is packing a detuned version of this engine. The Camaro is also rumored to be getting the same setup as well. Camaro ZL1 anyone?

I would love to see an LS9 in the Camaro, that thing will be out of hand. And yeah i want to see that motor with basic bolt ons, pulley, and a bad ass tune.
-Joel

638hp, that's a nice little bump up from the proposed 620hp number that's been flyin' around...VERY nice. :cool: :cheers:

Very nice!!

Thats sick

thought the cts-v has smaller charger

They vary some do 650, a friend of mine runs the dyno testng for gm and that is what he told me. Pulley, tune , intake, full exhuast, injectors (if it needs it) i bet you could easily see more than 700 to the tire

thought the cts-v has smaller charger

maybe the 1900 series not the 2300?

I remember Digital Corvette was saying this thing would have 650HP like 2 yrs ago...not too far off. Sounds like a bad ass vehicle.

W

so what did the ZR1 end up doing at nurburgring?.....I never saw the offical time

those are some good numbers..

im honestly disappointed. I wanted to see at least 650

Take it with a grain of salt but its the only source so far.

yea problem is I cant watch youtube @work, days gots its blockd

Take it with a grain of salt but its the only source so far.I would maybe take this with a grain of salt as well but Chief Corvette Engineer Tom Wallace is looking at possible 7:20s at the 'ring:

I would love to see an LS9 in the Camaro, that thing will be out of hand.

The LS9 variant used by the CTS-V is called LSA and packs 550hp, the Camaro will also be recieving it to answer the Mustang GT500.

Ive always wondered, would displacement on demand be feasible in a forced induction engine? I'm wondering since they made the 'most efficient for the power' comment.

They will probably rate it at 650HP the final year of it.

W

ok. fuck my plans to buy a house. i can do that whenever. the world is going to end in 2012 anyway (dont tell me otherwise or i may change my mind). you think i could get financed at 18 for that zr1 with like a 30 grand down payment. lol jk, but i may seriously do that for the camaro if it does it fact have that engine... i can only imagine...

Wow the car looks amazing during its top speed run, looks very smooth. And the guy driving probably has the greatest job on the planet.

Impressive numbers for a factory vehicle. But, some of you are acting like 638 crank HP is a huge deal. You can buy an LS2 2005-2007 C6 Corvette and install a Procharger D1SC, headers, cam, tuning and see over 750 crank HP. For much less.

Yeah but to think your getting this great amount of power from factory with warranty is just awesome. Course if i had the money for one it would definetly not be stock for to long.
-Joel

Warranty and reliability is enough reasons alone to take this over a conventionally modified LS2.

edit: So what, I can build x, y, or z to be faster or do something better than a ZR1, ain't that hard. Now trying to do a modified vehicle to be just as dead nuts reliable. Sorry, been there done that; and it ain't cheap.

umm.. not to be a dick but, they have CAFE to worry about, drivability, durability, FI working with DOD, etc. of which procharger and a h/c/i ls2 does NOT adhere to. to have this engine designed and built, and put in a relatively affordable package (when compared to its competitors ) with a factory warrantee and an SAE certification is nothing beyond amazing. this engine represents 53 years of small block design.
so basically, a procharged, h/c/i ls2 corvette is neat and all but why do that when you can have a factory backed 638hp corvette that has the potential to run the ring in 7:2x for less than half of what the car its going against costs?

remember you now have a viper (yeayea, looks etc, but my point stands), a pricey car when a simple procharger/bolt on c5 or c6 could beat it for less money.:engarde:

Nice kinetics...but I would rather have an LS3 M@RO.

This car doesn't have displacement on demand. Even the LS3/L92 6.2L do not have that. Also, read my first sentence. I said it was impressive for a factory vehicle, I love this car. BUT, I was making a point that 638hp isn't that big of a deal like some people here are acting like it is. That wasn't a dig at the car, only the amount of HP as a number itself. My C6/Procharger statement was just an example of a simple combo that exceeds that figure. And it does so in a similar car.

As far as warranty, how many of you guys would trust the mechanics at your local Chevy dealership to wrench on your $100K+ car? The bozos here in Houston have trouble changing oil in my GM vehicles. Lets use the example of the supercharged C6 again, you can buy those for $40-50K, that leaves you another $50K to spend in case of "warranty" type issues. Think you'll use $50K worth of warranty repairs?

As for my Viper, there is no "cheaper" version to buy and modify to exceed the performance of the highest model. When you can buy brand new '08 C6 Corvettes for $39K, then that definitely becomes a valid alternative to start with, over a $100K+ version of the same car. I sure wish they sold new Vipers for $39K, I'd have bought one and modified it to exceed the performance of the higher end model.

I agree with that.

Right. Because the ZR1 is simply a regular Corvette that GM threw a supercharger on...

Honestly, you don't think a 640HP stock Corvette isn't incredible!? :rolleyes:

I don't think the horsepower is unbelievable or anything, I just think it will be an all around awsome car; Wieght/Power/Handling package. Sure you could put 85,000 into my 15,000 dollar camaro and have a faster car than the vette, but this is a factory car with alot of tech and engineering to make it one of the best super cars for the price.

Edmunds is predicted the LSA in the CTS-V will be closer to 570hp than the official estimate on Caddy's site right now.

Pulley swap anyone? I know if I afford the car 638hp would not satisfy me for long.

The fact that it comes with a warranty for that type of performance is incredible.

I've attempted to get Enzo beating performance and stellar reliability, and I can sit and look at my spreadsheets and say definitively: it's very hard to beat the ZR1 on cost and it'll still whoop me on straightline and it can waltz into a dealership when there's a problem. I have to pony up $3K everytime before my driveline can even be worked on.

So... about that ZR1? It makes me green with envy.

Manufacturers are hamstrung by a variety of varibles they have consider like regulations, emissions, etc. Owners are not. ;)

That sounds awesome. I'm a die hard N/A guy.. but wow. Imagine the hp potential of this car when modded.

I get the impression that the supercharger may not have that much left in it considering its displacement (2.3L). Aside from that, it seems like the LS9 could easily pick up another 50+ horses with a cold air intake and a top quality set of performance headers and complementing exhaust.

Good numbers.

Excellent car. But the comment about 50k in warranty work is spot on.

W

Take a standard C6 for $40k. How much would it cost to add an intercooled Supercharger, forged pistons and crankshaft, titanium rods and intake valves, dry-sump oiling system, dual mode exhaust, larger wheels and tires, carbon ceramic brakes, carbon fiber bodywork (hood, front fenders, front spoiler, hood, roof, roof bow, and rocker panels,) flared rear fenders, beefed up transmission with dual disc clutch, beefed up rear end, retune the Active Suspension, and the aluminum frame?

Next question...
In 10-20 years from now, how much will your modified C6 be worth compared to a real ZR1?

I have a feeling that simple bolt-ons (pulleys, headers, cold air intake, and a tune) will exceed 700hp. Probably closer to 720hp.
Why?
The stock engine is only seeing 10.5psi. The bottom end uses 9.1:1 forged pistons, forged crank, and Ti rods. Peak power is 100rpm before redline.
Increase the boost, spin it higher, and let it breathe better.

I'm going to go out on a limb and say that you could hit 800 crank horsepower without pulling the heads. It will probably require a solid roller cam though.

I don't even want to guess what a set of well ported heads would do at this point. The exhaust numbers on the L92 heads could be better and would definitely be a choking point. I'm wondering if the LS9 heads will receive additional port work like the LS7 does?

I agree with that.

I'm pretty sure that they wont let your average GM tech change the oil,let alone actually do any sort of warranty repair..If the dealership wants to work on these cars,they will have to get specifically trained people..That's howw it was with the '90-95 ZR1's.

The best bargin today is the 1LT Base C6. With it's 450hp LS3{Dyno Confirmed} it's only 50hp shy of a Z06 at 30K dollars less.

I haven't done much reading up on the LS9, but is the top end work substantially different from the L92's? Or did they run with a "lots of room for improvement" mentality on it?

If there's a lot of room for improvement, I would expect to see at least 800 crank hp out of the engine before breaking too much a sweat. Pulley + straight pipes+ better intake +tune.

The best bargin today is the 1LT Base C6. With it's 450hp LS3{Dyno Confirmed} it's only 50hp shy of a Z06 at 30K dollars less.

And the Z06 has more than 50 flywheel hp more than a base LS3 still {dyno confirmed}. It is more like 60-70rwhp difference between the two. You have LS3s with M6s in the 380-390rwhp range and Z06s in the 450-465rwhp range. That is a pretty significant difference, especially considering the Z06s upgraded brakes, dry sump oiling system, lighter weight, wider wheels/tires etc. The Z06 has more options standard as well (I think HUD is standard on the Z06, that would require 3LT on a base C6) and a base C6 with Z51, dual mode exhaust, 3LT, etc wouldn't be 30k cheaper than the Z06. The LS3 C6 is definitely a bargain though, I won't argue with you there.

You get an "F" in reading comprehension. I already said the ZR1 is awesome for a factory vehicle. Go ahead and write that statement down before you forget it.

So, in summary for you reading challenged:
1. The ZR1 kicks ass for a factory vehicle.
2. I myself, personally, feel that 638 hp is cool, but I'd want more.

2. I myself, personally, feel that 638 hp is cool, but I'd want more.

Then mod away. It seems to be what all of us do with our cars here, none of us are satisfied with our cars no matter how much power they make. I'm sure someone who has a supercharged Viper could think up some stuff to do to that ZR1.

That is exactly my point. I would modify a ZR1 for sure. But then the argument for "all that power with a warranty" is not valid any longer, right? Exactly my point again.

Summary part 2 = GM warranty work is sketchy, and most of us wouldn't use it anyways. So, who really cares about "all that power with a warranty" on a $100,000+ car? I sure wouldn't base my purchase decision on if the car had a warranty or not. If you can afford a $100,000 toy, warranty work is probably the least of your financial concerns.

You're just mad that the Vette is making more power than the Viper.
Viper-> :punch: <-ZR1

I want a warranty, and you can definitely bet that a good chunk of hyper-car buyers that don't modify vehicles would also want a warranty. Don't assume that because they have to money to burn means they actually want to burn it, wasting money to waste money is tacky and cliche.

Take for instance Ferrari's: Your either in with a factory blessed race team and they perform your maintenance or you use a favorite dealer: why? Pedigree. Applies to Porsches as well.

Same ideology would apply to the ZR1.

Mods and it's out the window, up to dealer to pick and choose; that point everyone pretty much agrees on. But if your going to modify out the wazoo and you try and have the warranty cover questionable problems (Oh the humanity! I snapped my axles... don't blame those drag slicks over there!), then you shouldn't be modifying in the first place as that person obviously is either crooked or broke.
Moral of this story: "Pay to play and use a little common sense."

From the factory the numbers are awesome!

But yes, if/when (lottery permitting :eyes:) I get one I would add headers, do a pulley swap and a tune to put me over 700. Wouldn't be able to let down a loss by anything under 100k on the street.

ZR1 = :drool: :hail:

Basing whether or not you buy a car on its warranty is stupid, I agree. I think most people are just trying to point out that there aren't that many vehicles out there (maybe none) with this kind of power coupled with a decent warranty. I doubt anyone will be thinking "OOh a super car with a warranty, I'll buy this one!", they'll just be drawn to the performance/collectability etc.

Hard to justify buying a $100K Corvette as not being "wasteful". That is a large purchase that isn't really a necessity, and I'll bet 99% of the population would see ANY new Corvette as a frivolous cost. Since we are gearheads, our viewpoint on the subject is just a bit skewed from reality. We easily self-justify car purchases :)

I wouldn't compare Ferrari trained techs with high salaries to the GM dealer warranty guys. I've rarely been impressed with any GM warranty work, and I've owned dozens of brand new GM cars. Also, most Ferrari owners view their cars as the ultimate perfection in stock form, Corvette guys tend to modify. Nobody thought that people would be modifying the Z06 as much as they do, but now we know otherwise. You will see plenty of modified ZR1 Corvettes, and plenty that are just parked in a vault.

Not mine :devil:

Who said I was mad? I may still buy a ZR1. Then you can be mad at me :D

I may still buy a ZR1.

If I had the money, it's definitely something I would be considering. The value of that Corvette will, theoretically, only go up over the years. The first production supercharged Corvette, that has to be worth something in itself. :)

Nine Ball, I'd be bawling in tears if a ZR1 didn't get modified; that'd be a travesty.

I was just quibbling over a minor point, but I do hear you on the generality of your statements. :chug:

Not to argue, but don't the GM techs have to undergo special training/qualification to even touch the Z06s/ZR1s? They aren't exactly normal Corvettes, and their owners would be MIGHTY displeased to find some retard broke the dry-sump system on their LS7...

Well i sure hope that if you have a Z06 that they have a specific mechanic doing all the work, same with the ZR1. Last thing i would hate to find out is the same mechanic that works on the cobalts is working on my Z06/ZR1.

Yeah, but on the flip side if you have an Aveo you could say that a ZR1/Z06 mechanic fixed your car.

I agree. I thought it would be closer to the 700 range. The preliminary figures on the C6 forum from some of the insiders was that it was going to be around 680. Still a nice car!

LMAO yeah i guess you can its more like the sword can cut both ways.
1. You got your Z06/ZR1 and an average mechanic is working on it, yet your paying an assload of money to have just that and average mechanic work on it.
2. You have a mechanic that works on the Z06/ZR1 working on your Aveo, and just like that when they are done your going home in an Aveo.

Im sure as in the past they will have specific mechanics that will work on the ZR1. Im sure they will just pick a mechanic that works mostly on vettes, then just train that guy on what proper mechanics for the ZR1. I would love to be that guy, GM call me!
-Joel

It shouldn't take that much to ge it past the 700 mark anyways, its boosted now. Look at cars in the past like the 03-04 Cobras, Twin Turbo Supras, Evos, STIs, all these are boosted cars. And the slightest mod to them will make instantly more power than what the factory imagined. I can't wait for the first dyno vid of one with intake, headers, exhaust, pulley, and tune.

Yeah , that really don't sound so high & mighty since Shelby's Super Snake Cobra has "725 HORSEPOWER" !

But Shelbys Super Snake thats rated at 725Hp gets the warranty dropped. And don't forget the Mustangs still weigh as much as an Abrams tank. Im sure the the ZR1 will completely outperform any "snake" that Ford or Shelby can throw at it.
-Joel

I've read that only a very limited number of dealerships will be able to sell the ZR1.

I also read that this engine has the capability of making well over 700hp, but the head cheifs at GM said that it wouldn't make top capacity in its first year.

Im sure the the ZR1 will completely outperform any "snake" that Ford or Shelby can throw at it.
-Joel

Even way more so turning left and right!!

Lower weight, cg.
Crazy better weight distribution, and instant center.
Wider wheels and tires.

...and probably a hundred other things I don't have time to list!

Here's it doing 205mph...

The passenger has balls of steel. I could get up the nerve to drive a car that fast, but I couldn't sit in the passenger seat without having a heart attack.

Man that engine is just SINGING at the end! Beautiful car! It almost seems like it could do more with a higher gear or an extra cog....unless the top speed we are seeing is drag-limited...

IF anyone has balls its that driver, at the 200+ range he was constantly checking out the reading. The car sounds great, and climbs easily to 200mph, but im pretty sure it has to do more with the gearing. For it to perform the way they say it will im sure the gearing is set for more all around performance than top speed runs. Which it looks like it wont have any problem performing at any range of the speedometer.
