Title: Over 1 BAR on 996T? Post by: NOTORIOUS VR on June 19, 2013, 08:57:10 AM I'm trying to get more then 1 BAR boost on a standard 996 Turbo, but it seems like it only really like to see that kind of boost before the air charge/motor is warmed up.
From what I've read, some people are saying that to consistently get over 1 BAR all the time you need to run upgraded WG actuators. Does anyone have any experience w/ the 996T? My logs indicate that I am indeed requesting more boost, and I've made the PID maps for the WGDC quite aggressive once I didn't see an increase after the car warmed up so it must be a hardware issue. Title: Re: Over 1 BAR on 996T? Post by: NOTORIOUS VR on June 19, 2013, 11:19:00 AM Welp, by the looks of it anyone running 1+ BAR consistently has a modded/different WG actuator.
After a few more thoughts I figure the stone cold motor raised boost levels are coming from the fact that the spring inside the actuator is cold and therefore stiffer giving the boost spike. Once the actuator/spring warms up and becomes softer the party is over and boost falls. Title: Re: Over 1 BAR on 996T? Post by: Topspeedwolf on June 19, 2013, 03:54:30 PM Hi NOTORIOUS VR
Do you have a Definition File ? I am looking for a very long time for a File. Title: Re: Over 1 BAR on 996T? Post by: ddillenger on June 19, 2013, 04:06:33 PM I do. I'll post it later.

Title: Re: Over 1 BAR on 996T? Post by: NOTORIOUS VR on June 20, 2013, 12:57:53 PM Good to know, thanks! and yeah, more testing last night is starting to reveal that there is a hardware issue on the car.
Even with pinched WG lines the boost did not go past 0.7 BAR... only strange thing is when it's cold it makes 1.1-1.2... WG feel fine, so next step is to check for boost leaks etc. Logs show ECU is req more boost and PID values for N75 are @ 95% (although I cannot seem to log actual DC with Durametric), but all signs point to hardware in this case. |
