Do these dyno # seem to high for LS2?
My LS2 with a vararam, ported TB, and bullets put down 371/379 on a mustang dyno today. I know the mustang dyno's are usualy high but I was only expecting 360rwhp at the very most. What do you guys think? I am still on the stock tune.

Just use those numbers to evaluate the gains of future mods.
People get touchy around here comparing dynos... this thread could get real long real quick...
For reference, my 06 Z51 M6 dyno'd 355rwhp with Callaway Intake, GHL Exhaust, and tune (on a Mustang Dyno).

Yea I know how it can be on here. I just wanted to see how accurate that dyno was. I have some buddies that want to dyno their cars but if this one is way off we will have to find another.

Well mustang dynos usually read lower than Dynojets. If you're concerned about the numbers you can always take it somewhere else and have it dynoed again, just for reference.
On the other hand, i've seen some cars come out of the factory stronger than normal. They're usually referred to as "freaks".
I remember when I had my 98 Z28 M6 I had it dynoed. It was stock with nothing more than a MTI intake lid and a flowmaster muffler. It dynoed 326rwhp & 330rwtq which comes out to be around 360-380hp. Strange from a car that was rated at 305hp stock. A buddy of mine had a 2001 Z28 M6 which came with the LS6 intake. He also had SLP headers, Loudmouth exhaust, SLP intake lid and a few other mods here and there. He only put down 317whp/329wtq if i remember correctly.
You my friend, just might have a freaky LS2.
Just my .02 cents

I hope I have a freak! haha Unfortunatly there are not many dyno's close to me in WV that I could get another dyno. In fact I had to drive up to PA to get this one.
On another note. The shop charged me $50 for one pull or I could get 3 pulls for $85. Is that reasonable?

His #'s are right in line.
"There are no c6 freaks"? Apparently you either haven't read or don't believe dyno charts people have posted.

You're right I don't believe the high dyno charts. These can easily be manipulated to show high numbers and are really only beneficial to measure gains when adding performance adders. GM on the other hand has to meet the guidelines of having all their c6's meet the stated hp within 2%. It's the law.

I agree with most, dyno's will vary soooo much that it is pointless to get caught up in how much a stock or very lightly modded car puts down. I can go to 2 different dyno's in STL that are both dyno-jets and put down 10-15 rwhp different on the same day blah blah blah.
Use them to compare where you start from and after performing some mods to see what type of gains you got.
Better yet, take your car to the track and let's take a look at your trap speed.
According to your power numbers D-Rod you should trap around 116? My car traps right at 115 with only 360/358 rwhp.(per the lower reading dyno)

Thanks for everyones input. I hope I did not come across like I think my car is stronger than most with the same mods. I just thought they seemed high and it is so hard to search for others dyno #'s anymore.
BTW- The shop owner said that since we were so high above sea level that my numbers should have been even higher. I told him that the #'s seemed high to me and he agreed but he stood behind his dyno, naturaly. He said the dyno was just bought this year and stressed how acurate it is. lol If I can find another dyno close by I will do another pull and post the #'s. Then I guess I can be the example everytime someone posts unnaturaly high #'s.

Well I stoped by the track today. This was the first time I have really ever launched a car hence the below par #'s but I was happy being my first time.
60ft- 2.06
1/8- 8.28
1/4- 12.60
MPH- 114.5
I know the car has alot more but I am just learning. My first run was a 12.96, second was 12.70, and last was the 12.60.
