It will definitly take away from those high numbers you have....you should really get some numbers with the new rear end and ds....
This makes the 490 claim inaccurate now...

Not a "claim", the car made 490.... I have the dyno sheet and video to prove it. I'll dyno again within the next few months with the 9" and see what happens then.

Which clutch are you using?
That thing is going to fly with good track prep and a better DA.

In my opinion and experience a car that dynos at 490rwhp and with an estimated race weight of 3500lbs (Car weight 3300+you at 200) should trap faster than 112 at 7300ft which corrects to ~124mph at sea level.
As a comparison my car with a race weight of 3400lbs traps ~122 at 2000ft which corrects to ~124 at sea level and I know my car does not make anywhere near 490rwhp.
Although I am sure that your car makes good power and your ¼ mile trap speed is strong it just does not match a car with 490rwhp.

A 490rwhp vehicle weighing 3600 lbs should trap around 123 in the quarter at sea level. If the race weight is 3500 lbs, it should trap 124 mph in the quarter at sea level. Add 7300 DA to the equation and the mph will drop around 7-8 mph. That means 115mph at worst and 117mph at best.
With trap speeds of only 112mph NA in 7300 ft DA, this is only 119-120mph at sea level. Certainly strong, but it would suggest some missing ponies. We never did see the dyno graphs showing the SAE correction. Is it possible to post them up?

Well guys as a sponsor of this site & the person that dynoed the car I'm a little offended that you moderators are basically calling BS on Sean's dyno graph.
First thing in the morning I will be more than happy to post the graph again with SAE clearly on the side of the graph.
I'm really disappointed in you guys, you'd think moderators wouldn't be so biased towards their cylinder head of choice that they would attempt to discredit a vendor on this board. You both are basically hinting that the dyno sheets are completely false & that the results aren't accurate. How do you figure Sean's results are somehow that far off from the power your car makes Patrick? He's running a larger camshaft, and a cylinder head running a port developed by one of the leading LS based cylinder head specialist in the country.
This is Sean's first trip to the track with a rear end & a sticky tire. How about instead of attempting to discredit him & one of the leading shops on ls1tech you just give the kid a opportunity to practice & hone his driving skills.
Once again I'd like to offer up the opportunity for ANY heads cam stock bottom end car to race my heads cam stock bottom end car. I'll run the PRC cylinder heads against any heads cam stock bottom end car you want. No matter what the valve angle!

Dyno numbers and track numbers with a M6 can be two different animals.
I believe the dyno numbers, and they are impressive. The track results are a little weak but most of us get better over time (probably with the exception of me driving stick).
I'd have to be there watching this guy make passes to see what power is left on the table.
There would be a big difference say having Rodney (Smokino1ta) wheel that car and the the owner, Rodney has a ton of fast passes with a T56 under his belt.
Play ball but nicely.

Jason,
I hate that you took offense to my opinion and it was never my intention to question your integrity.
My opinion is based solely on the data in this long thread. If the heads were AFR, ETP, or TEA my opinion would be the same.
There is no question in my mind that when you dynoed the car it did put down the 490rwhp on your dyno. But the fact still remains that a 3500lb race weight car making 490rwhp should trap faster than what this one did.
Maybe the driver was short shifting; maybe the car weighs 3800lbs?

I'll write this one off as lack of racing experience or an improperly set up combo (suspension, gearing, etc...) for the track. A properly geared 6-speed with that power and weight would trap in the 123-124 mph range at sea level. But, it wouldn't run like that the first time out, without dialing the combo in.

Take it from another 6spd racer that when my car is right and I am right, it runs strong for the weight and hp that I lay down. Now , when the trans was giving me problems then it was a different story. My trap speed goes down from 121 in good air to around 119 and that is still not being terrible at driving a stick ,just not on par with what I can do when it is right.
Give the boy some time and he may get the trap speed up with some driving improvement.

Jason, there you go getting all defensive again. I did not say that your product was sub-par, nor did I even hint that another product was better so RELAX. I merely pointed out that with several runs that night and the best mph being 112 leads me to believe that not all ponies were present the night he ran. Do I believe the car made 490 rwhp on your dyno? Yes. Whether it was STILL making that power at the track is what I was questioning.
Not posting up complete dyno sheets after repeated requests only adds to the confusion.

weather and driving plays a HUGE factor. explanation:
car is a 02 Z28 with lid, catback, maf (330rwhp)
my first night out i got a cool night with low humidity.
best trap: 111
next year on a hotter, humid day, and not hitting my shifts as good.
best trap: 100
who's to say there weren't other variables? there is way too many other factors for people to be saying the car is great or a dud.
