I wanted to see who can claim the highest HP and/or TQ dyno numbers so far for a stock LS3?

I've seen a couple of stock SS's with 380 RWHP at our BBK performance meet a few weeks ago. I'm sure they'll post here. Makes you kind of disappointed when you've done so many mods and you get the same thing :(
I need a tune...

Wow, those are serious numbers for stockers. Yeah, this is true! or even a couple horses less! I know that the numbers can vary between cars probably 25-30 hp and very dependent on weather conditions. I hear ya, I need a tune too. But I'll plan on tuning the car once I get some new headers down the road (oh and a tuner).

My adjusted numbers were 368hp 372tq need to make an appointment to go back now that my exhaust is on before I do intake. Not expecting much but I want to see what each nets me.

being that the LS3 is SAE Certified, they are all going to make the same HP within 1% of the rated HP. The variance you will see in dyno numbers have to do with weather, tire pressure, engine/oil temp, how tight they strapped down the vehicle, and wheel/tire size.

And then you have to throw in the tolerances of the drivetrain (transmission, driveshaft, rearend/differential, half-shafts, etc...).

654 rwhp stock block. 7psi.

We had a couple dozen done on the same day, same shop, same conditions. They varied quite a bit! No where near 1% of the rated HP! Hopefully they'll post up here as we all got our dyno sheets e-mail to us...

Go by the SAE rating.

Dyno numbers can be all over the place.

you can strap and unstrap the same car and the dyno will spit out different numbers. that's just the nature of dyno's.

Mine was SAE adjusted. The dyno shop's AWD dyno was set up for turbo cars.

I'm trying to get a local group together to go to the dyno shop so we can use the same dyno on the same day under the same weather conditions.

That's a great idea - getting a bunch together at once. That way you will get a good baseline and as you perform future upgrades you will really be able to see the gains.

Yes, and it's less expensive too. Unfortunately, I only have a couple of people in the area interested.
