I know he upgraded a few things, nothing serious maybe he'll chime in or i'll ask him!

At best the difference in airflow (VE/BSAC, or how much air is needed to produce 1HP/min)between the 2 engines can be 10%, and that is way optimistic...which means that torque should be within 10% of each other.

Joe,
It was the quote of Vicious in your post that I was referring to. Is this getting confusing or what And I agree with the rest of your statement except the part where a higher boosting engine outlives an engine revving higher, it all depends how much of each and how it is used..You can control at what RPMs you shift and peak torque will remain unchanged as long as you shift after 5K RPMs or so....but dial down the boost to save your engine and you loose the torque..
Scott (Divexxtreme), Todd did not say that K16s can go anywhere beyond 600HP on a 996TT. If it is your car you are referring to, that is another story, we all agreed that sth. is different in your runs, as no other K16 based car ever got close to your trap speed. I don't see where this debate fits in this discussion though
Happy New Year.

From what I've read throughout the forums, I get the impression that there is various customizing, specialized tuning and refining that can be done to "higher horsepower projects", which will create spectacular benefits. As mentioned in this thread, an example would be equal power using, relatively, less boost. Nevertheless, what I really like about the "high volume" EVOMS kits, specifically the GT700, is the transparent, "cookie cutter" aspect of it. In other words, I appreciate how easy it is to find out exactly what is going to be done to the engine (in detail), what the cost are, what the expected power should be and the numerious happy customers there are running around out there.
Though there will always be specialty customizing which can make any car just a little bit better than the next, I feel comfort knowing there are countless GT700 kits with the exact same set up and the owners have been very happy. I just wanted to give MAJOR KUDOS to EVOMS for making so many of these kits available to the "little guy", like me

Also worth noting-- there are still many coming to this forum that have not followed the blow by blow(no pun intended) evolution of the 996 TT performance gains and are only starting their path.

I never ran the car with higher than 65% on the Boost Controller...on the street, at the track, or on the Dyno-Jet where I made 600 rwhp...so to be perfectly honest, I may have actually ran my 10.6 @ 136 at only 1.2 BAR...since 65% is what I used for boost on the dragstrip.
It depends which boost gauge you believe to be more accurate.

On my "Pump" or Low Boost setting, the OEM Bar Guage reads: 1.1 Bar and the Greedy Boost Controller is reading: 1.02 Bar @ 40%.
So, I guess my question is: What is a more accurate reading - The OEM Bar Guage in the Instrument Cluster or the Greedy Boost Controller? I would assume that the Greedy Would be just as or more accurate since it is tapped right into the boost line right?
If this is true then, I actually could up the boost just a bit on the Greedy Boost Guage to get the full 1.3 bar on Race Gas even though the OEM Bar Gauge may now say 1.4 Bar? Is this ok?
Scott, Marski & Others - Would ignoring the OEM Bar Guage and just going off the Greedy Boost Controller by the wise thing to do even if the OEM states 1.4 Bar and the Greedy states 1.3 Bar? Give me your advice please!
BTW: When my car put down the 490 AWHP, it was onlt at 46% @ 1.22 Bar.

Dave,
yes you are correct and the 1.22 bars can still not be accurate because when u let off the gas u get a spike... so ur actual boost at WOT maybe be even lower then 1.22 bars...

If it's on the intake manifold (imo where it should be) then you will not see a pressure spike as it's occurring before the throttle blades. If it's pre-tb then yes you will get a slight spike, but even so it won't matter as it's only spiking against the TB blades.

So basically I would be safe by reading what the Greedy Boost Guage states and tuning the boost according to that and NOT the OEM Guage? As I tune it up and get a reading of 1.3 Bar on the Greedy, I may see 1.4 Bar on the OEM - This is ok since I am only seeing 1.3 Bar on The Greedy - am I correct? I would figure like you said before, the Greedy will most likely be the most accurate over the OEM right? I just want to make sure I am not overboosting or doing it if the OEM is 1.4 and the Greey is 1.3 on 101 or 103 octane.....
Thanks Mark!
