How many are there??
I’m wondering how many CERTIFIED (actual proven numbers from dyno runs) LS2’s are out there in the entire country ( NA LS2’s) that have 524 Wheel Horsepower or more that are stock motors , no strokers or other internal builds & no larger injectors & fuel pumps but simply LS2’s that do the norm.... mass air , P&P throttle body, intake , cam , CNC heads & headers w/ X-pipe & no cats are aok but that’s it. I mean REALLY telling the truth.... are there only a handful? Or are they a dime a dozen?? And if they did achieve 524/5 did they do it at 28 or 29 degrees of timing ?
plz let me know. Thanks much.

Curious as to why you are asking? 524 off that cI takes a lot of work to get.
Id believe mph from a timeslip way before some dyno sheet fwiw.

I know of several at 525whp and a few at 523whp, but not a single one at 524. That must be really rare.

Dyno numbers are not always the same. The guy that does my work leased out his dyno for a week to a guy and the first car he did after that it it suddenly put out about 50 HP more than any car with same combo as mine, so once it was re calibrated, the numbers fell back in line.
All I am saying is that sometimes people play with the calibration and if a number looks too high, it probably is.

Just like placing a hot cup of coffee next to your home t-stat will cause your AC to kick on, the same trick on the dyno sensor will cause a power reading compensation.

I don't get caught up in the dyno numbers. Mine only put down 450rwhp unlocked but ran 128mph with a 28" tire and a 2.56 gear.. Mods at the time were vararam, ported tb, ported Fast102, TFS225s, custom cam, ARH 1-7/8 headers, high 11s on the compression, ss3600 and a dragpack. It was actually on a no. 8 plug at the time because it was really setup for nitrous. I think the timing was 27* IIRC.

Hi Everyone
Thanks for all the retorts( the nice ones) I apologize because first of all I NEVER SAID MY CAR HAD 524RWHP. After 9 pulls, 4 on straight 91 & 5 on higher octane ( 2 on 95) & then 3 with 98 octane. The numbers were all in the high teens ...516-519 & then we increased my octane to 98 & she put down 522.8 so call it 523 & she was very hot by this time . My tuner is one of the best & he DOES NOT PAD NUMBERS TO MAKE A CUSTOMER HAPPY ! If we stick to my original thread then sure.... ok... my LS2 only did 515(515.6) on pump gas(91). I know not all of us do but when ur NA I figured just about everyone runs an additive or does some good mix to help as much as possible. I don’t track my car or tk her to the drags as I’ve had over 2.5 decades of racing so being a bit spoiled with where I live( 20 min from ANGELES CREST HWY) lots of HIGH SPIRITED DRIVING ( sorry guys I’m older & not real good at all these acronyms) the routes Me & my Z06 buddies take is an immense amt of fun. I consider myself a well abv average driver &even with full race Wilwood brakes I can EASILY OUTRUN THEM with under 525whp so I often wondered why anyone wud want much more.... that’s only if ur “ RoadRacing” so to speak. Anywho.... thanks much for all the input. Is very much appreciated. Btw, I’m sure someone will ask who my tuner is but will ask him before saying so. But I will say MOST of u in California probably know him. Hv a Happy Thanksgiving everyone!! Tk care & Godbless. Rob

Lost on the question, since stock LS2 motor in the 05 to 08 vets make 411hp stock, and can be re-tuned to around 426hp in oem conditions.
As for ASE certified Dyno's, they are out there, and calibrated correctly. The problem is to keep having the dyno's re calibrated and re-certificated, that it really cuts the dyno's down to the car manufactors that have the money to justify such (and them actually post the real numbers, isntead of some other marketing ploy to devalue the motor rating for other reasons).
Hence in 05, GM rated the LS2 at only 400hp, since they still have C5 z06s on the lots making 405hp that they needed sell. A few years later, GM published the real HP SAE number at 411HP instead.
As for what a N/A LS2 motor can be built to, the sky is really the limit instead.
Hence the higher you can rev a motor, the higher HP you can get out of it. This is the reason that some 4 cylinder motors that rev past 9K, make over 1KHP.
So the real number to be looking for on a 3000LB weight car, is the torque value of the motor, since that drops around 5.4K, and puts the motor into the usable range of a street use RPM's isntead.

why dont you NONE experts try posting some engineering FACTS backing that up
my car doesnt have that never said it did but theres quite a feww CF folks that disagree

tell me why that is? do dynos only post odd numvers or something? when you answer something , TRY EXPLAINING your " comment"
so us non vette EXPERTS will know as well

another SA comment like i toild the others, instead of comments that serve no purpose at all but show an inability to possibly converse with actual meaning
try explaining WHY 524 is a ' SPECIAL" number
