with the 10.5cm2 turbine housing the ability to flow at rpm is greatly increased...
what I'd much rather focus on however is that TORQUE LINE!!!! thats not a torque curve lol. That has to be one mean car on the street.
props to a sick powerband!

Once again I'll try to find logs for he 1psi boost drop and honestly tird of everyones smartass comments and stupid useless remarks. Stop the hating. Binh got a tatse of the evo today so you could aks himn for impression. On a side note while on the highway cruising at 80mph the devil took over and smashed the gas pedal and before I knew it we were at 150mph w/out a sweat and only 6800rpm.

Warrtalon is right. It is almost impossible to prevent boost taper to redline. All you can hope for is reduce it. Those who say that they do not get taper are relying on their gauge and almost all gauges are off. The only way to find out is to log your boost.
The pic below is a table of 10 3rd gear logs. The numbers w/o brackets in the max boost recorded in those runs. The number in brackets is the average boost. Even with the exed set to 100% boost at the high end, there is still taper. Boost peaks @ 21.6-21.7 and tapers to 19 by cutoff. A taper of 2.6-2.5 psi.
If your car is not tapering, then please post a log showing it. No log=No proof.

As far as the 3.5 exhaust goes, does it make more power, on a big turbo I am sure as far as stock goes not positive on that. I had a great deal on it and couldnt pass it up.

Right, and like I said, you were running 24+ psi. Hello, McFly, try to pay attention. We are talking about running 22psi and only tapering to 21psi. You ran 24.4 and tapered to 21.7 - that's a drop of 2.7psi, which is almost exactly what NJ showed above and thus further supports our argument. Btw, it doesn't matter that you have the stock BOV - that doesn't have anything to do with the boost taper. It just means your turbo is having to work harder at 7000rpm to maintain 21psi due to the weak BOV. This means you turbo is being less efficient due to blowing more hot air just to maintain the same boost levels than if you had a good BOV...

Thanks for showing a real log, though. You and NJ have shown actual proof on this side of the argument, but we haven't seen anything from the OP.
