Anyone Else Dyno in At 390+ RwHp Stock?

[Nighthawk89]

Ill have dyno sheets posted early tomorrow morning. I wasnt able to make the trek yesterday to pick them up. Traffic in california is like waiting in line at a theme park on "everyone gets in free day".

My bad. It was 400 to the wheels not 390..

[ChocoTaco369]

My car dynoed as high as 376rwhp and 380rwtq bone stock. And it was an 80+ degree day. It was hot, folks, and I pulled right off I-95 and onto the dyno 10 minutes later.



That was bone stock. There are all kinds of tricks you can play with the dyno. I could've thrown ice bags on the intake and let the car sit for an hour. You could play with correction numbers on the dyno's software. You can play with tire air pressure. I'm sure there are plenty of things you can play with that I am totally unaware of. I mean just look at it - there is a difference of 8 rwhp just in between pulls. Do you really think there is a difference between a car that dynos 380rwhp and 390rwhp?

Who cares what your car dynos?

It pulled in at 400 at the wheels and there wasnt any tweeks made as this was to get a "before and after" result test. The likely hood of them wanting the numbers to be lower on the first bare stock dyno pull is more likely then them trying to tweek it to show more horsepower being stock and less of an impact once the supercharger was on. The purpose of this thread was to see if anyone else had dyno'ed at the 400rwhp mark before any modifications not to bash on anyone elses stock dyno pulls.

We get what you're saying. But the point people are trying to make here is that on a stock LS3. You're simply not going to dyno 390 let alone 400rwhp on these cars, unless you're dealing with a funny shop.

I don't think anyone is taking offense, I mean shoot they better not. ... They're just dyno numbers. Which is why most drag strip Champs rely on trap speed and times versus numbers on a dyno. Because they vary greatly.

I dyno'd at like 350rwhp on a really stingy dyno after my headers and Cai with a tune.

some pretty good figures here...all i know is my new baby is way faster then my 4.6 mustang..

I'm not necessarily saying that the numbers were intentionally fudged, just some shops set up admospheric correction, and some don't bother. My shop doesn't.

Interesting read on different dyno outputs.

Have not had my 2015 on the dyno yet.

My 00 Z28 however put down 323/314 at the wheels with just a muffler delete... through a 4l60e even.

Blew that motor up a few years ago though

I guess never say never..
And im just assuming Magnusons Superchargers Headquarters Doesnt play in any funny business.

Before the tune the RWHP was around 370RWHP if I remember right. I could certainly tell the difference after the tune.

I have an R6P (pre-production) SS and the guy that did the tune said that the pre-production cars have more HP than the later production SS's. I don't know that to be a fact but he said the 4 -R6P Camaro's he did tunes on all ended up with higher HP than the later product Camaro's.

And there it is.

Dynos are PRECISION tools, not accuracy tools. Taking your car to a dyno at Shop #1, then doing some mods and going to Shop #2 to compare numbers is meaningless. Two different dynos, two different days, a useless comparison. A dyno should be used as a tuning tool only. Same shop, same day, minutes or hours apart as you're changing settings it is useful. It is also useful for manufacturers that build and design longtube headers, exhaust systems, camshafts, etc. If you control enough variables you can use the dyno to gauge performance and modify to optimize said performance.

What you dynoed stock at some shop is meaningless. Your car can dyno 10rwhp higher than mine bone stock and it won't mean a damn thing. All it does is show how inaccurate dynos are. If your car dynoed 390rwhp stock, it's just as fast/slow as the same Camaro that dynoed 370rwhp stock at a different shop assuming the transmission, gearing and options are equivalent. The whole "factory freak" thing is unfounded as well since dyno performance does not translate to track performance, and track performance is really what matters.

Couldnt have said it better, on the money Sir!

It is too often that people get caught up on the dyno numbers game. Factory freak, you say? I say, let me see your car runing and Ill tell you...

Bingo... thank you!

Stock or not they are selling the idea that they do the same thing everyone else does and are getting better results. Now when you lose races to cars with lower numbers they will just blame your driving, traction, etc.

It won't be their fault, they helped make your machine superior to everyone else's.

It's marketing and you fell for it, with the notion that you have some factory ringer as well. You are happy, they are happy, everyone wins.

I've worked at a dyno shop before, no one wants their dyno trash talked around town.
