Post Summary about Porsche reaction with more than 1000hp

after long reading hard driving and allot of analyzing
i've found that with very high power im facing problems with traction even if i disconnect the traction the car wont disconnect the traction 100% there will still be traction !

EVOMS 4.0 Ltr
The problems we faced were all due to the OEM PTM (Traction management) system preventing us to make a clean WOT run. The car performed flawlessly at 25 PSI of boost where it went the fastest speed. As soon as we turned up the boost / power, the wheel slippage caused throttle cut as soon as we shifted into 5th gear. The throttle from 5th gear on was reduced to 60%. We tried everything we could throughout the weekend to correct this in the software as well as different driving styles, tire sizes, etc but we could not get a clean WOT pass with all of the power on board.
and later i went back to old Threads and found out that
Evoms faced the same problem with there 4.0Ltr 1200Hp in the texas mile and that was there major issue for not accomplishing there target!
pls check the vid in the run @ 2:20sec

in other hand i also found out that the GT2 react absolutely different than the 997tt in the GT2 one of my frnds here running the GT3076.82 Protomotive package when he set the high boost disconnect the traction control and run a test Run all signs flash on the board which means the car has 0% traction control in this condition the car react insane and like a wild animal

motec ? i believe evoms should come out with a solution
Todd in protomotive is working on 5 engines in his work shop 2 of them will go for 997GT2 which m sure will not face problems 3 m not sure
but am sure he'll try the engines on 997TT and if he run it on streets he'll defo face the traction issue but on dyno he'll not

Porsche marketing material states that "if you'd rather enjoy your 911 Turbo unassisted, PSM can be set to standby at any time". The key is "standby" although the button says off.
It is never completely turned off.

Almost all of these systems will give you more rope to play with but not enough to hang yourself with.

FYI: Todd’s car is two wheel drive. They removed the front drive train (well, at least it was removed when I saw it). So I guess they are playing half the traction you are??? When I spoke with Todd in early Dec he mention they had difficulties trying to control the wheel spin and getting it to “hook-up”.

It's an untapped market really! Its kind of ridiculous that Porsche has the least aftermarket support for engine management.

AWD motorsport was working on a standalone solution i think.

9FF came across a 375kmh speed limiter on their 997 cars when the took them to nardo. It took them by surprise as their 996 cars weren't affected by any limiter. Very strange that anyone would bother fitting a 375kmh limiter, the idea of 375kmh and limiter in the same sentence is ridiculous.

hahhh now the 996 boost gage can read what ever boost comes to it but the 997 boost gage will only read 1.2 as a max on the 997tt and 1.4 on the gt2 boost gage and there's another undiscovered thing called 375 speed limiter lol ridiculous i wont bother and ask why !

Removing the Front Drive Train would make the car a Vette, yes it'll spin.
