Dyno of my turbo charged 993 VRAM @ 10psi
I am very pleased with the results! By keeping stock compression the car has that wonderful quick response of the NA motor.
The downside is I have to blend in race gas to make it all work cause I kept the stock compression. I plan to install water/meth injection in the near future to solve that problem.

Impressive numbers. Very smooth transition up the band except it dips a bit at apprx 5K RPM, do you know why...what is your A/F ratio? Can you share some of your turbo specs.

AF ratios were 10.9 then dipping to 10.5 at redline. When I data logged it on the road it showed slightly leaner so I need to recheck that.

5+ years later the car is still running strong! No surprises. Just oil changes and plugs.
Recently I installed a Greddy electronic boost controller to cure the 8 to 6 psi boost taper. The torque curve is completely flat now. That should get me 500 WHP (600 Crank) with the new 6,900 redline.
I have played with various boost levels over the years and settled on 8.7psi. It seems to be the best setting to maintain good overall balance through the twisties etc. The dual throttle body VRAM allows you to be very progressive with power delivery and make the most of the setup. I have run up to 14.7 Psi (with proper fuel and knock monitoring) for about 700hp. While exciting down the straights it kinda ruined the balance of the car.

While there has been a LOT of interest nobody has pulled the trigger. I am getting close to pulling the ad down. Not one single person has taken the time to come see the car and go for a ride. It maybe one of those situations where I was never meant to sell it.
I have been able to fund most of the real estate investment opportunity I had the money ear marked for by being creative. As that need changes so does my need/desire to sell it. I gotta say after last night's ride through west Marin I can't image a better setup 993. I would be hard pressed to let it go at this point.
