A little birdie dropped off a note today regarding the '10 Camaro Z28 with supercharged (1.9 TVS) 6.2L/LSA:


The Z28 will also have 550+ HP that's underated. The dyno chart showed 520 RWHP 492 RWTQ. Changing a pulley and adding a tune & exhaust the thing had 615 RWHP and 602 RWTQ. They said that that was with a mid size pulley. They have smaller ones.

On the downside the car will weight at or over 4000lbs.

The SS is still going to be 430hp from a LS3 (3900lbs). It's gone 12.7@113 in testing.

The 2011 Mustang GT receives a 400hp/360tq 5.0L/4v revised Modular with VVT and 6spd but no DI (yet) and manages to stay around $30k. It will also only weigh around 3600lbs--PtW says it's going to be quicker/faster than the Camaro SS.

ChryCo, wake up and get the 6.4 to market already. The 2011 GT500 is going to be one SICK puppy--that's without direct injection. The DI numbers for these motors (LSA/5.4) are CRAZY. Unless ChryCo puts a blower/turbo on the existing powerplants (even a N/A 6.4) we won't be able to keep up.

ps--don't believe what the rags say about the stang getting a 6.2L Boss V8. It's a truck motor and that simply isn't going to happen, especially with the new/retarded CAFE regs otw.

At least we still have some time left to make the Jeep's faster. We'll still have the AWD street killa' advantage too.

What are the chances of all these rigs making it to market with gas prices? I'm just imagingin a board room of stuffy-shirt bean counters giving the big THUMBS down as people clammor for mass produced 40+mpg cars.

Everything I've posted about has already been given the greenlight for production, trust me I can't wait to see them in person either. ;)

There will always (at least until 2020) be V8 Mustangs, Vettes, F-bods, and other high performance cars. What will be different in the future is that they will be produced in lower volume (consequently priced higher) to allow the number of sales of Foci, Cobalts, Calibers, etc. to offset their gas guzzling ability.
From what I hear we're good to go until at least 2015 with GT500s, Z28s, ZR-1s, etc. though we'll be seeing a lot of turbo 4 bangers (even in vehicles like Explorers) in the near future. It's not all bad news, at some point (not until 2012+) Ford will stuff the 3.5L TT V6 in the Mustang (there will still be a V8 variant) and that little bastard will have the abiity to make more power than any N/A 6.1/6.4--weighing less than 3500lbs to boot.
Makes me wonder what Dodge is doing with PD blown 6.1 they've been testing for years...:confused:

Big cubes and N/A has always worked for Mopar. I hope they keep it that way. Throwing a blower or turbo is the easy way to make HP.

Sorry but an S197 will hand our Jeeps their ass on a twisty course, assuming equal power--in '11 they'll have a much better PtW ratio and will literally smoke us. Here's to hoping ChryCo steps up.

Several people who post on the CZ28 site actually work for GM... I know of one guy who can be canned by tomorrow if he even mentions what he knows (another words he stopped talking as soon as the hiatus/hush order cleared).. It's hard to believe information when it pops up out of the blue and the few guys who seem to know what is going on won't/can't vouch for it. That said I am still reserving judgement until something is verified.. (aside from it looking like crap...I can make that call already..haha)...

Granted the LSA version is a bit on the chunky side... But a gain of 500ish #'s and 200more rwhp.... Gotta give a little to take a little. I'd give back 400#'s though! LOL:eek:

Hater! Hahaha! I like the way it looks. But it really is one of those "love it or leave it" looks.

I know Scott quit posting up as often as he used to. I was hoping my post would bring some people out of the wood work. Then again, I haven't posted on that board in a looong time. This year's my 10th anniversary for being on that board. :o

There are already cars that beat the piss out of us in rwhp.. they are not AWD so we smoke 'em. Why does it matter if they have 100hp on us if they can't hook up?

Well, when they do get traction they can make up for lost time.

Anyone that's not brand loyal that's into performance cars.

It's going to be easy to get 700rw from that motor with pulley/tune/exhaust with the stock 2.3L TVS blower--and it's ~300lbs lighter than a Viper.

Sounds like Chevy tore a page out of Ford's playbook. ;)

Like it or not, we're going to start seeing a ****load more small/smaller displacement motors with blowers/turbos.

That and these cars do hook as evidenced by their 0-60 times. It may take more driver to get it out of them, but they definitely have more potential.

That's a bit Naïve... please post of your 1/8th mile times... a rwd car with 100 more rwhp than your awd vehicle is going to spank you period. 1/8th or 1/4 mile it doesn't matter which. Post up your magical 1/8th times that makes you believe you 'rule' the 1/8th mile.

The only way they will SPANK us....is if they are running slicks! street tires vs street tires with 100 hp more it's gonna be close!:(

Very nice...wonder what the bumpstick I had would do in a jeep like yours (230/244 116 LSA)...

Just for an example -

2006 Z06 bone stock (street tires as they come with)...
7.168 @ 102.45mph

2008 C6 Bone Stock (Automatic 2.73 geared - street tires)
8.040 @ 92.824mph

It doesn't take 100 more horsepower for a rwhp car to run you down in the 1/8th... I am not sure what you meant 100% but it sounds like you are a bit 'overly confident' of your capabilities in the 1/8th mile. You are obviously running me down (I go 8.6 @ 85mph in the 1/8th) but I also have ~300rhwp (no where near 100 more than you ;) )...

Maybe you could elaborate a bit for me?

all I know is I beat both a viper and a z06 in the 1/8th.....both drivers sucked I guess....they sure were spinning alot on the line! My best races have been against evo's (awd).......maybe it's 50-75 hp more? Are you saying a rwd with street tires is just as good as an awd with the same hp, and same weight in the 1/8th.....that's just ridiculous.

Never said that at all.... but your not talking about cars of equal weight or horsepower... if we are going to talk apples to apples it's a completely different story. You can't simply say 'it takes xx rwhp to beat xx awhp'... too many variables.

The fact that you beat both a viper and Z06 in the 1/8th means you have encountered people who have trouble driving (not a very good indication of what RWD can do on street tires)... I think this explains why you are so confident.

Bone stock 2002 C5 Z06 - Street tires (as they come..)

More on the Z28/LSA and welcome back the GN:

I saw a vid where one of the engineers at GM ran 11.9 @ 123. I don't know what's done to that car, I was led to believe it had DR's and that's it.
I saw the test car with the pulley,tune and exhaust, no cai ran 11.2 (the MPH was cut off of the screen.)

A Grand National is in the works. 400+ HP turbo charged 6 banger. Very early stages.
