gt3071r.
what is interesting about my setup is I'm running 1,55 bar at the middle and my ecu reduce boost up to 1,2bar at 7000rpm. power still rising.
why? because my engine is not producing power with higher boost on high rpms.
so he pushed 1,7bar from 4000rpm till the end but no extra power.
I think I need bigger heads.
I'm not using any external boost controller my original ecu control boost.

what boost you are running?
strange my friend is running 996 turbo with bell cores, gt3076r, big injectors, 70mm europipe, big tb, big pipes before turbines and big pipes before tb and ecu from giac.
boost 1,4 bar and his 100-200 is 6,2sec.
power? 608 Ps and 825 Nm from Maha dyno.
he runs rear wheel drive only.

we are running gas from first supermarket gas station.....
my engine is not knocking even with 1,8 bar boost but not producing power
I will build engine with big heads hope will run 1,8 till the end.

That my friend is fast....especially that the gears weren't changed & its a manual. 
hope to see you in Texas. By the way my 60-130 run was pulled right off one of my mile runs, No boosting with two shifts.

I think the 1/4 mile like Powell said especially if you know how to read the times and the splits and the whole time slip. Is a very good way if you only have one thing to go off to judge a cars performance. It tells you if you crunch the numbers what cars could have ran with more traction and better gearing and etc.
Yes there are cars built for the 1/4 mile but you will be able to tell that by how quickly they ET in relation to trap speed. I have gotten pretty close to the point where I can see a cars powerband and capability based on its time slip. Now with that being said in some situations adding the other data as far as the mile, and 60-130 times definitely brings a cars whole performance envelope to the table.
In the mile since you can't have slicks your really running a dance between traction and applying full power. So for numbers extrapolated from that you don't get the cars whole performance capability. You get a good idea of the max its capable on street tires but the Mile surface is worse than most drag strips. You can also build a car for the mile as well optimized to run quickly just there.
I like 100 to 150 or 100 to 200 times because most powerful cars have something approaching traction by that time. Unfortunately 60-130 is very beneficial for P cars and AWD cars so while it may be very good for the P car world its hard to compare to other cars.
In the end everyone builds there car for the discipline they want to focus on most so its hard to compare cars built for different purposes across the board. I hope I have not bored you guys, and I will get off my soap box!

A good way, but definitely not the "best" and/or "only" way.
I know of many drag cars that are geared for the 1/4 mile specifically...that pass through the traps at pretty much their maximum terminal velocity. So their times don't mean much, other than they are really good in a 1/4 mile.
You also need to consider the traction required for good 1/4 mile traps as well. On street tires, 60-130 is a more accurate gauge when comparing AWD cars to front-engine RWD cars, to rear-engine RWD cars, to cars on street tires, removing the ability to heat the tires, etc. It sort of levels the field.
IMO, the 'best' way (that captures acceleration capabilities in the most common driving situations) is a combination of 1/4 mile trap speeds, 60-130 times, and dyno numbers. Obviously, standing mile or 0-300 kph runs are outstanding ways of validating overall power and the ability to maintain that power over a significant amount of time, but the inherent difficulties that come with running at those speeds and distances (locations, safety equipment required, events per year) make it a very difficult performance measure to use on a broad-basis.

if you've never done it, next time baby launch and think consistent smooth shifting, see how high you trap..you'll be surprised. I like that the 1320ft mark can be used to calculate your hp by what you trap, which is usually spot on in telling hp(unless you are a REALLY retarded driver, but not thank's to pdk you're an ace
) Going for trap speeds takes out a lot of the driver error of going for et'ing. Someone on my subaru forum ran 11.7 with 337whp and at 116mph. He could trap(back in the day) almost 120 on his mis shift runs or bad runs..(that's kind of my point right there, the ~119mph are his hp)

I think in order not to have any excuses and have good idea of car overall perfromace is good to run 60-186 or something like that...but there is not many place where u can do this safely, so 60-130 is to get an idea..
Speaking as a customer of SPI..
THERE is NO HARDER TEST you CAN DO that WE DO it HERE...
NIGHT after NIGHER 0 to WOT, 20-30 1/4 runs 12 to 6 am, all night long....
MAX BOOST sometimes even OVER that, just to BE FASTEST and show better RESULTS...Then going to track and doing half day sesions...
All Switzer csutomers are crazy here, all of them know each other and all them RACE most of the TIME...that is why they tune the cars, tioll the end and no STOP...MAX POWER !!!
WE want to get some Evoms and Proto cars here and I am sure they will do as fine as well, at the end its all comes to customer service and support and how far does your tuner want to go with you... I mean we have tuned SPI 750 may be 3-4 times over 2 years to get even more from it and we did get better resutls.
Do they have any customers in EUROPE that can come to MOSCOW UNLIM with thier cars or can meet us in EUROPE...???

temp was 14c, Full tank, lb230+ driver :P
here is the number for the zo6.
60-130 6.3 sec in 270m with 2 shifts
100-200 5.04 sec in 212m with 2 shifts
200-297 11.28 sec in 818m
