2010 Camaro Dyno Video / Graphs

[Chris@Livernois]

Yesterday, we had a customer bring his 2010 Camaro SS in for a tune. The car is a bone stock automatic.

The baseline numbers were 318 RWHP / 345 RWTQ, the tuned numbers were 339 RWHP / 360 RWTQ. Similar to our G8 tunes, it did pick up power, but our transmission calibration makes it feel like a whole different car!

Earlier in the week, we had another customer bring his in for a baseline. The car is a 6-speed manual, bone stock with 850 miles on the odometer.

The numbers were 378 RWHP / 381 RWTQ.

I said it in your other thread, but I'll say it again here.

I can't believe there's a 70hp difference between the two. That's depressing for those that wanted an auto (me). Stock LS1 numbers but weighing 300-400 more is not what I wanted.

Those numbers are very close to what we see from a G8 GT (auto) and slightly higher than we see from a G8 GXP (manual), but they are in the ballpark.

I wouldn't be discouraged. I think with a CAI, Catback, and tune the auto car will run excellent.

or... our most common package for the G8 GT is our stage 1 cam, headers, and CAI and we have one customer with these mods and a converter going high 11's and another customer with these mods + ported intake/tb, and U/D pulley going 12.2 @ 119 mph on street tires with a stock converter.

You have to take into account the drivetrain loss with the automatic. So there isn't a 70hp difference between motors. But just going by these dyno numbers, I would say there's a 40-50hp difference at the motor. The A6 may be making more like 380 hp at the motor.

We'll need to see some more car dynoed for sure.

What do your stock G8 GT's dyno? automatic
And what do your G8 GXP dyno? automatic

A stock G8 GT makes around 315 RWHP.

All but one of the GXP's we've done have been manual transmissions and the only auto was baselined with less than 50 miles and then we installed a Magnacharger, Rotofab, Corsa Exhast, and tuned it. I feel the numbers were very low due to the mileage. It made 330 RWHP stock.

Our GXP manual was baselined with 20 miles, then again at 1,000 without any mods and it picked up 20 RWHP.

Once they get some miles, they all seem to make around the same baseline numbers.

I'm not doubting that with a few mods they'll run great, but the stock numbers are a bit disapointing. I know people say dynos are just tuning tools, but they still show how an engine is performing.

Either these cars are tuned severely conservative from the factory (which might be the case considering your post-tune numbers), or the AFM really puts a damper on the power. I'm pretty sure it's not the transmission, since the 6L80E is just as efficient, if not more, than the 4L60E was.

Since the A6 Vette has basically the same driveline as the A6 Camaro, with the only big difference being the engine, I think it shows how limited (from the factory) the L99 is compared to the LS3.

Yes, I'm aware of the loss the auto will have compared to the manual. 380hp at the crank is not good, considering GM rated them at 400 at the crank. Either the 6L80E is very inefficient (which we know it's not), or the L99 is a bit overrated from the factory.

Well here is the deal on that..we know they have the same head design, the same parts in the shortblock....L99 has a little less compression and the AFM system with the 4 AFM lifters, and a little different cam spec. So...essentially to correct that buy the AFM delete kit, remove the stupid AFM system, and use a thinner head gasket to bump up compression...if you planned on a cam swap now would be the time, since your already replacing parts, and this would negate the small difference in stock cam specs.

Just face it guys, if you bought an L99 (like I did), your gonna have to mod and mod quickly, because your already starting out from behind vs the manual (and behind the Mustang or so it appears).

Yeah, we'll have to see a few more cars dynoed before making any conclusions. In the different thread (L99 1/4 mile baseline) it was mentioned that that car made over 330 rwhp stock.
But 320 rwhp is very common for an Automatic LS2 GTO, and they are also rated at 400hp.

So go figure.

But the 345 ft lbs of torque is really nice. That's considerably more than my stock automatic 06 GTO made.

Good info

My dealer emailed me to come up and check out a SS on monday, I want this car that I ordered but having to play catchup to the LS3 has been my biggest gripe. First it was only 25-26 hp differents then the dynos started showing the real numbers. Been reading threads today and the L99 owners/some are not happy with their HP/performance. If I was still able to drive a maual thats the way I'd go. Just have to spend a little more money to catch up withe LS3's thats all right ?

[Scott@Bjorn3D]

Well I for one am upset. GM tells us it is a 400HP car and it does the same 0-60 as the LS3. In my cars case that is total

I am very unhappy with the setup of my car now that a Mustang kicked my but so badly.

Here is ny baseline run done this morning at Maryland Performance Center.
Certainly not big numbers, but it’s what it is.
I got 305 RWHP, and a guy with the same car but a M6 got 343, so I’m figuring it’s realistic. (Delta of 38 RWHP L99A6 vs. LS3M6)
They say the Superflow is a touch conservative
Hopefully in the weeks ahead I’ll be able to report some gains




Ok, so when your not as happy with whats under the hood , you make up for it on top of the hood (at your favorite bar of course)
