My results. 340 WHP and 320 Wheel Torque. High 13s in the 1/4 mile. 0 to 60 mph 4.7. What makes me sad is that I got the same times on an APR stage 2 setup. My APR stage 3 setup ran to 60 in 4 seconds and 12.5 in the 1/4 mile. My car is AWD and a DSG.
I found out that a CTS Boss 3071r Gen 2 with a Nostrum HPFP and ZZP injectors and TTRS LPFP and a Torqbyte PM4 on 26 to 29 PSI measured by a analog boost sensor on a P3 gauge can't make over 400 WHP. Before this car made 375 WHP on ZZP injectors on the stock HPFP with an APR stage 3 kit on a UM tune.
Shop and UM say the car is done. Guess I am stuck and struck out on this build setup. Hoped I could get 400 wheel but I guess I have a laggy K04 setup based on dyno and straight line acceleration numbers. Find a build that works and copy that. I will need to find a way to enjoy this setup.
So after having a few weeks to think it over, it hit me, the engine was heat soaked during these times. I feel like an idiot not thinking about it.
The first three dyno runs were done trying to get the dyno in the right mode and the numbers of 343/320 was on the fourth run. We were in a time crunch so we didn't wait for the car to cool down.
On the drag strip, I sat in line for 20 mins on hot asphalt so the engine must have been heat soaked. The engine was idling most of that time.
The turbo is larger and is more laggy.
The transmission slips more clutch due to the tune or more torque so that adds delay.
The car at upper twenty PSI is very fast to me at 1000 feet elevation when you get the turbo to spool up. I know for sure it has more power at this elevation then Denver.
I will keep learning and seeing how we can get more power if possible.
Once I have the answers I need I will drop this.
