Thanks Protomotive!

Don't make your own interpretation as mine. I also always said that it should be 2 shifts to make it real life comparison and comparable, you were the first one to post one shift runs because you could not get better than 8.6 seconds and wanted to go with the one shift...I didn't and don't care until now
In fact, I never authorized my run to be posted here and I would like it to be removed (Divexxtreme please). With the integrity around some of the numbers posted I certainly don't want to be part of the circus.

Let's define LAG
Ok, all you guys comlaining about LAG... Let's get to the bottom of what it really is, and that you're calling it LAG, when it's not.
LAG would be the time it takes for the turbo to spool up, that TIME, not rpm, and I would mostly want to define that during a time when the turbo is in it's proper operating range, so not I wouldn't compare the lag of a GT35R to a K16 at 2500 rpm's because I wouldn't bother putting a GT35R on a car that was to have it's optimal operating range there...
Same deal goes for comparing a 1000hp twin-turbo viper to a 1000hp formula 1 car... Let's not talk about power to weight here, just LAG time vs. usable rpm range.
So, would you try to compare the 1000hp tt viper at, say 4-5000rpm's to the lag of an older gen. 1000hp f1 car?, no... The F1 car's usable rpm range is more like 9000-14000 rpm's, and they designed the turbo to work properly under those conditions. Just like the vipertt, well, for one, you couldn't compare it to the f1 car at 9-14k because it'd fly apart!
So, Markski's car has GT35R's on it because he has a usable rpm range of about 4000-8200 rpm's, and the turbo's response TIME, aka LAG, during that period is very similar to a K16 on a stock 996tt in the 2500-5000 rpm range that it's very usable. That is, the time it takes to spool the turbo (LAG) when the engine is in it's usable rpm band.
VRalexanders car was also developed to run high rpm. His heads are actually flowed to go 9000rpm's, but the Porsche bottom end is just not designed to go there, so we've limited him in the 7800-8000 rpm range where he's making peak power. His also has a usable rpm range from 4000-8000, like Markski's. Putting a K16, k24, GT2871 or GT3071R on there would be senseless as the turbo would be done when the engine is turning on. And vice versa... Putting a set of GT35R's on an engine designed to only run to 5000 rpm's would be horrible... The engine would be all done by the time the turbo came on.
So, please, let's use the terms properly.
LAG = TIME to spool the turbo during the usable rpm band it's designed to operate within.

The time that it takes you to reach 60-130mph will not matter, he will be ahead of you anyway.
But again, for the sakes of the rankings, great, but if you are interested to know how honest your tuner is with his numbers and what you paid for, then you would compare apples to apples, or at least try to. It all depends what each one of us is after at the end of the day, no right or wrong answer.

BTW this may seem funny Jean, but wouldnt "real world" be more like optimal, as in doing what you would have to do, for best/faster results?

You are determined to convince me that I am seeing this as a contest..funny.
I can crank up the boost to 1.3 Bar and post a sub 6 second easily, or easier still, take my car to a 5% incline and tilt a bit the unit etc... Do you think anyone would know? Please. I could have a 4 second run posted here if I wanted.
This car that Protomotive built kills anything in its way on the track, lap after lap, this is the only thing that matters to me.
Willie thingy..Not my game.

Jean you are awesome, im just messing with you, i would never challenge your knowledge, to shortly get schooled/shot down, it just wouldnt look good for myself! hahBut it is an interesting concept if you think about, only reason why i brought it up!
Jean,
You appear to have yourself in a Dander
KPG-> That's my point about Markski's vs. Jamies car... I would probably start a gear lower in Markski's vs. Jamie's due to the rpm range they work in. And have a lot more FUN doing it
Markski's car kinda ruined most of the driving in the other cars now ;p In a good way though...
I still think he needs to publish acceleration runs as ring tones for everyone... What a glorious sound that car makes

you can have faster time between the 60-130 and be behind the other car because he took the lead on you earlier, you cannpot get back to him (distance wise). It is a bit tricky, I know.BTW My comments were not posted for you!

I do this all the time and there is no problem with motec or other BC, same as extrenal BC... Using it in the EMS can give you some nice featers and there is alot more going on then dragracing, when thing should hold toghter for like 7 sec you can have and diffrent approch to things
Like I said, of course using the BC functions inside an AEM or Motec can be productive, but they are not used by anyone tuning a car to the max. I'm sure you know the reasons since you tune cars....

I experience very little lag when I line up on the highway....as long as we're using a 3 honk start....which I can never hear anyway
