C6 dyno #'s inside!

[Miriah]

Here are the first dyno pulls on the car with no mods and 185 to 195 coolant temp, it now has 444 miles on the odometer.

001- 358.4 Tq 356.4 HP
002- 355.1 Tq 355.2 HP
003- 356.2 Tq 353.3 HP

444 miles from the original post.

Now, that is more like it. :cool:

[StealthZ06]

Where's all the haters now???

[02blackws679ta]

awesome

[MJSbossman]

It probably had headers. ;)

[roSSco]

:woot:

@ 13-14% d/t loss that puts it right on the money! ;)

[Sally 5.0!]

Is this one a ringer?


:umm:

[Beavis]

I'm guessing 370+ after 5k miles

[JohnnyLS2]

Wow, that pulls almost to 6500! :eek:

That's over 410hp at the crank. Looks like you got a strong running car. :D

[Mike's02Z28M6]

Congrats! Great #'s :D

You got a few more miles to go before you bring her to the track?

[CT Morgan]

Looks more like expected... break in time DOES have an impact after all. ;)

[roSSco]

13-14% is the generally accepted d/t loss on a C5. I would assume the same for a C6. That gives a figure of 402-405 ;)

The engines are hand built and are dynoed before they leave. They are pretty much as broken in as they are going to get. Don't expect much power to come from "break in". You'll get more power from switching out the shitty 87 octane that GM puts in from the factory. With premium fuel I'd expect a slight increase, but the cars are dynoed out of assembly.

Id like to see some flow #s on the heads.:cool:

Actually, the C5's have more than that. They have more driveline loss than an Fbody. They have an IRS suspension which isn't as efficient as a solid axle. They are more around 15-16% with a manual. ;)

Better not dyno your car too much...it'll hurt resale value..

Making back to back pulls over 10 times, plus making pulls on another dyno at 44 miles will break the engine in enough. We are talking maybe 2-3hp over 5000 miles. When the engine is dynoed like that, the piston rings have already seated and are ready to go.

When I had my new motor installed, I said, "so will my car free up more horsepower once I drive it?" Speed Inc. said, "we already dynoed your car, its as good as broken in..."

I'd trust what they say over some internet racers. I have yet to see someone take a bone stock C5, dyno it. Then after 5000 miles go back and dyno it under the exact same conditions and yield a gain of significance.

I've seen it a ton of times on LS1 F-bodies...on ls1.com

I disagree with this. I've spent a lot of time on Corvette forums and they say 13-14%.

Like I said. Same dyno, same temp, same DA, same elevation, etc. There is no significant gain.

I'll use my car. I bought it, dynoed it after I put 800 miles on the car. Bone stock, 305.4rwhp/31xrwtq. I then dynoed my car 4 months later after I put an extra 5500 on the car. It was within 1rwhp, and 3rwtq. I then installed my exhaust and the car made 318rwhp/328rwtq.

Believe what you want. That car WILL not pick up anymore than 5rwhp from a "brean in" period. The gas has more to do with the numbers than the actual breakin.

And these are the same people that bitch about what license plate cover looks the best.

That information is inaccurate. If it were to be true, then an Fbody would be 11-12% driveline loss. :rolleyes:

[jdsgn]

the dyno will not equate to the same as 5000 miles, motors loosen and the tolerances get better and more power is made, things do settle enough from the factory that you can rag on it if ya wanted out of the showroom, but there is still more to be had after the motor loosens up a bit

He is right at least as far as Z06s are concerned.

My car dynoed about as low as I have seen any 02+ Z06 dyno. It did 347rwhp stock.

That is a 14.3% driveline loss.

I have seen an 04 Z06 dyno 362 rwhp stock.

That is a 10.6% driveline loss.

On average, I would say its close to 12.5-13%.

[Borla]

Moved to appropriate forum. :) Let's get the LS2 area rollin folks. :cool:

u just killed it

[GarySS]

First off those are killer numbers.I have seen dyno numbers from 335-356....remember each dyno will be slightly different so take your numbers with a grain of salt....On the subject of correct driveline % loss......there is no exact number but a range....The bottom line is rwhp....That is what I go by....:drive:

On average, I would say its close to 12.5-13%. Mine did 347 bone stock as well, with no "dyno tricks" like letting the motor cool for a few hours, packing ice on the intake, or putting huge fans right in front of the car while it dynos.

However, it responded VERY well to mods. My car's at 423rwhp currently with just CAI, UD pulley, LT's, a Corsa catback, and a modest cam (227/224).

I can only imagine how well the LS2 is going to respond to these sort of mods.

:shrug: Really, the driveline & differential isn't going to take 14% of 800hp. It's going to take more of a flat #, not a percentage.

[Miriah]

Car is 100% stock. We just picked up the car Monday night left the dealer at 11:45pm. :)

Sweet as hell I love the car... I'm not a vette girl at all or I should say I was never a vette girl before...but I LOVE the C6.... The ride, the looks ah so nice!:D

[Chief Pontiac]

Thanks for the info Miriah and those results should get better when the Vette has some miles on it. :)

I want one NOW!!! I had such a hard time falling asleep last night. I was just so excited about the C6. LOL I still can't believe I'm saying this! Ha ha... I just love the car inside and out, my only wish is that they didn't do the head lights like this...maybe it will grow on me I don't know but as of right now I'm not found of them.

It truly is a "keyless" entry car. All you need is to have the keybob with in 3 feet or so of the car and you can "push botton" start it or "push botton" open the trunk. They ONLY key hole on the car is for the trunk and you can only see it if you bend over and look up for it. To get out of the car it's also a push botton feature no more handle to grab to open the door...

I just love it I really do.... I'll have the pics up tonight just have to bug Phil to load them for me. :p

[Chief Pontiac]

Ya its one beautiful car and make sure you post some pics.Cant wait till I get mine.:)

didnt they say it would have 400 hp?
dang how did i get in this forum :D

[Chevcamaro18]

Good numbers but for some reason I was just expecting more.

[triggerjerk]

:hmm: 356/358.... Don't 405 hp Z06s dyno about that stock?

[Cam]

Threads merged.

[BurnsRubber]

Very impressive.:)

They only ran 13.2 on Motorweek last night, but it trapped 112MPH. That's a strong run, good for low 12s with the right driver and traction. Should be a beat on the freeway with that redline.:D
