For those members that have turbo upgrades already installed here is a thread to let members know which upgrade you selected...You can also post supporting data and results here as well for others to review to help determine which upgrade best suits one's own personal goals...
Which Turbo Upgrade do you "currently" have installed?

Where is the real comparisons? I am certain this has been beaten to death on this forum. But what I cannot seem to figure out is why no one is bragging with real data about their results?
When you are doing a virtual dyno there is no standard for replicating the test. The gear your in, the temp, the location, the altitude, fuel, the person conducting the test, etc. Running your car using the virual dyno is useless if the tests are not consistent between those who are testing to use for any meaningful comparison.
Lest not forget here in the US we measure torque and HP as torque in FT LBs, and HP normally in WHP as in at the wheel. Across the water, they measure in BHP aka at the flywheel, and Torque in Newton Meters. These are not the same. Normally there is a 15% variance between BHP and WHP in our car. Torque is about the same variance. Yes I know, HP is derived from TQ.
And when reporting results, for them to be meaningful, both numbers need to be on the graph to show the relationship to each other in regards to RPM, and it would be really nice to see boost against RPM for your setup with your parts. Saying that your vehicle makes 240whp, or saying your vehicle makes 260WHP and 300FT TQ, without the graph means nothing, because if you are making all of your power at 5K, what is going on from 1Kto 4900K? Remember Boost is a measure of restriction. The higher the boost number don't always mean more power. If you have an efficient system, you actually can have less boost with more power.
In addition, how about sharing everything you have done to the car in addition to the turbo. We almost need a form to fill out on this forum to keep it consistent.
Obviously a tune is not a tune, and they are not the same between tuners. Where National Speed may go about it one way, DHM would do it differently and so would adam on the exact same turbo based on experience, and again it really matters where you are, altitude, temp, on the day you did it and using a real dyno and the brand of dyno you used. That's why Adam says buying the lifetime tune is important especially if you move.
With any curve it is about "Power under the curve" not peak. For anyone who does not know what that means, when you are looking at a dyno graph, the higher your lines are over a larger area of RPM, the better. If your curve starts off on a 45 degree and climbs to peak at 5500, you are outside of the normal driving RPM range. When you are running around on the street, you cannot be running to 7 grand every shift, well I guess you could, but not as much fun IMO. You want your torque to come on quick and taper off as HP climbs, but if takes 5000 worth of RPM to get there your max power is only good for 2000 worth of RPM. AKA NOT A LOT.
If you have real dyno numbers, not virtual dyno numbers, share them here, don't be shy and don't be greedy. This is not about I have more power than you, this is about being scientific about what we are doing. There are lots of people on this forum that would be interested, not to mention everything we post is available on the entire internet, so you would sharing your information to the world.
