if you don't have experience with Dynapacks as pleas don't make any comment about it!, your statement like "highest reading dynos out there" are based on your own experience?,
and as to your desire of track results: that's really reflecting the change what about the weight of the car? Tires and wheels? Driver's weight and skills? etc. etc. etc. those are huge variable factors, isn't it?
Thanks

a dynapack reads very high. higher then a dynojet.
yes it does reflect track times. i dont care if your car weighs 6000lbs and that your a suck *** driver. if you run 20.138 before the swap and then 18.43 after the swap then clearly there is a change. or am i missing something

[SIZE=3][B] a dynapack reads very high. higher then a dynojet.
what is "very high" honestly that's doesn't sound very scientific , I can explain why one is more accurate and the other is not, but unless you show me the same car at the same temperatures running on Dynapack and than on Dynojet: I could only quote you "or am i missing something"

it will reflect track times in the same conditions, including temperatures, same track etc. but if you noticed my post, I'm not building this car as a drug car, but as the ultimate street/durability car, so it doesn't really my concern on the track times. and one more, is a track times will show you the real scientific improvement of the head change? So ok after the change with the HeadGames head we will be probably faster, how much faster is a big improvement and wharf doing a HeadGames head conversion
im not trying to be a d!ck man. not my intention. but a dyno like everyone says is a tool. even if it reads the highest or lowest. the track is the best place to see improvements or issues. you get a slip from start to finish. they can tell a big big story. your *** dyno on the street wont tell you jack compared to what the track with timers will tell you.
i understand your a street driver and you want reliability. but beeting the crap out of the car on the street is more abusive then going to the drag strip 11 sec at a time...... so what your not a drag type guy. bring it there to learn about your gains/looses and move on to the next mod you want. then do it again. compare and learn. your guessing on the street.

Well, what is a street/durability car? I don't even know what that is. If you never take it to the track, then you'll never know it performs. You can't even do anything on the street. The problem is you are claiming a world record, but all you have is a dyno sheet from the highest reading dyno in the world and with no track results to prove anything. I think this head is probably awesome, and I'm glad HeadGames is "in the game" with Evos, but think a second when you say things like this:
Does showing a dyno comparison when you changed from the stock ECU to a Motec, gained 1psi, and got a retune show real scientific improvement? We don't know the gains because of these other changes. We also don't know if the car is any good, because all you've done is hit the throttle in one gear while stationary. That's why track results mean so much more...
is a track times will show you the real scientific improvement of the head change?

maybe I'm missing something?
Are you claiming that I haven't improved anything in my setup according to the dyno results? And my change will not take effect on the track? As a "street guy" I can tell you that the change is dramatically noticeable and especially the torque improvement is phenomenal, and for me a torque improvement is much more important from getting extra few more horses at the top end, but that's me and maybe I'm dreaming
so I'm not guessing anything on the street, I'm living the street, and with all the respect to the track (and honestly I have) the durability of your car, is not judged only by times, times important but you have other factors as well, just one of them is early nice torque

and beating the **** out of your car on the roads is much more abusive then a drag pass. but i dont understand why you cant figure that out.
im sure its a great head. well im positive its a great head. enjoy. i dont know what more to say. but headgames rules.

you are not helping me, and I am not looking for "your great help"
you are only writing in a very rude way, but I guess that's you
I'm not trying to drive you nuts, as you stated, that's probably you

im not trying to be rude
im trying to help you understand where and how to see the car is ACTUALLY working for you and your driving me nuts not understanding what a few people in this thread are trying to explain to you. i was trying to fix that but i guess you are thick headed and cant understand that real world results will show on the track not racing around on the streets good luck sir. you do indeed have a good company that built your head.

Everyone’s dyno reads low and everyone else’s dyno reads high... 
Claiming dyno records in general is pretty silly (IMO) and I agree with most here, take it to the track, get a time and then see how you compare to the other similar setups...
I'm actually pretty fond of Dynapacks, it's a great tool and unmatched for repeatability (FYI - I've seen Dynapacks that read higher than Dynojet, some the same and others lower...) A hp gain of say 20hp will be the same 20hp gain on any dyno, regardless if the baseline is higher/lower on one brand or another... Problem with some dyno is the repeatability, I've seen differences between 5-15hp just between runs on some other dynos, while the Dynapack is VERY consistent...
What I get out of this thread is the OP has a really nice setup and the HeadGames head definitely made power... switching the ECU and 1psi increase is not going to give you those gains...
