Ok guys. Initial dyno results are in. With conservative timing, rich mixture, and pump gas, she made 720RWHP at .9 bar. Next run, we will move the timing to where it belongs, lighten up the mixture, and enhance boost to 1.1 bar. Expected to run about 750 RWHP on pump gas and 860RWHP on race gas at 1.1 bar.

impressive power for not so high boost. your tuner decided to push the timing instead of boost route?

I'm hoping Craig will jump in here really soon because as yesterday he got to DRIVE the car for the first time!!!! I can tell you this as, I did Craig, the WHP numbers on this car will seem very very low as compared to the performance of other cars with the same power....For those of you that have followed this thread remember that the car turns 8000 RPM and has individual throttle bodies which changes everything compared to the rest of us with a more conventional factory type turbos that just have more boost. There is almost NO lag in this car and when it hits it's like a Freight Train ... almost like an NA car. To answer the question above ... the 720 "Rear Wheel" was done on a Dyna Pak at .9 Bar with 15 Degrees (which is nothing) of timing and .7 CO... very fat.. almost enough to make it miss but, this was for break in and making sure it couldn't go lean... Since the car has motec, later the timing will be set up to jump to something like 28 degrees until it approaches max torque where it will then back off to somewhere in the high teens I would guess then back to low twenties. I'll never know exactly because that the secrete of the tuner (Loren Beggs of 911 Design) but, Timing Bell curves typically go something like that and I'm sure he'll have a race gas map too... I personally feel the number will go higher than the 750 PG and 860 RG as quoted.... but, the way this thing is built it will always stay cool, live as long as a stock production car and have tons of drivable power. To put it into perspective if Craig were just looking for power in all seriousness this motor could go to 1.8 bar, bigger injectors and something like a modified GT35 turbo's and hit over 1300 possibly 1400 at the crank and then likely rip the case apart or something. We know this all to be true because this engine is modeled after another engine that ran at about 1000 Bhp in a race car for more than 300 hours without any failures at 8500 RPM. I don't know that anyone else out there has done that but, it's a pretty impressive testimony. Craig researched the heck out of this car and I honestly don't know of anything else out there that is as complete as this car....and I can personally tell yo the best part of this is that Craig couldn't be a nicer guy! This car is built as much for all of you that what to see something like this built but, don't have the time or means to make it more so than it was for himself... he's very unique this way almost that he has no ego. I think I can speak for most of you when I say, "Thanks for sharing this entire build with us Craig" I hope as many people as possible get to see this car in real life! I really hope the car makes it to SEMA this year... I'm going to do what I can to make it happen.. OK, enough butt kissing.. CRAIG!!!! TELL US YOUR IMPRESSION OF YOUR FIRST DRIVE IN THE CAR!!!!!!!!

The bottom line is that this project started out as an 18K engine and suspension mod and then grew into a passionate expression of my inner self assisted IN A BIG WAY by Cary and Loren Beggs. I do not know what else we could have done to this car. The list of mods is three pages long and there are over 400 pictures of the process.
It took 3 years to build and I drove it for the first time last Thursday in Ontario,CA and it was incredibly cool, and way scary, at the same time. The thing idles at 1600 RPM just like a race motor, which I guess it really is, and the acceleration will scare the crap out of you. There is NO lag in the acceleration. When you hit the accelerator, the engine raps just like a Ducati, I know because I have spent some time on a 1048. Additionally, the Tilton carbon clutch is absolutely amazing as it is butter smooth and holds very well under full acceleration. The sound of the motor under acceleration is nothing I can describe. It has its very own sound and to hear the suction of air under acceleration is nothing I can define other than to say it is incredible.
Cary is right, this project is a tribute to the Porsche brand and its fans and what can be done to create an incredibly fast car that can handle very well at the same time. I have always been in love with Porsche and its pursuit of perfection. The rear engine design may not be perfect from an engineering standpoint, but I will tell you, Cary and Loren Beggs have certainly spent a lifetime figuring out how to extract every ounce of power and handling out of the 911 configuration. I can tell you first hand that what I have is the coolest car I could have ever imagined and I will spend many years to come trying to figure out how to be the driver that this car deserves...actually, this car probably belongs in a Porsche museum as a tribute to the fans who have made Porsche what it is today.
In the next couple of weeks, I will try to put a video on You Tube of the car in action. I think we are going to take it to Willow Springs before it comes home to Scottsdale, Arizona. I will also see if North Scottsdale Porsche (Penske) will let me put it in their showroom for a few days so people can come by and see it first hand.
We are close to the end of this thread, so thanks to everyone for your kind words and support through this build...and more than anything, many thanks to Cary and Loren for their endless ideas and help in building such an incredible street and track car. It is perfect. Long live the Porsche brand!!!!!!!

Wow! What do I say...certainly a better analysis by Cary than I could ever have stated.

). I'm really happy for you to see it all the way through. You seem like a really candid and genuine guy and didn't ever once come across as bragging or arrogant through this process. You just seem like a really upbeat guy who felt you could help others by sharing your build/experience with us and that shows just by the fact that you'd like to share it with as many people you can by putting it into the showroom to share with those of us that have followed this thread. Also, you seem like you're truly going to enjoy and appreciate the car and all that went into it. Not everyone does, infact I'd say MOST people don't. Most people would rather just open their checkbook and buy the fastest thing off of a showroom floor. Thank you for sharing the the good and the bad with us. Now comes the shakedown part and to work out the inevitable bugs that only appear once actually on the road detached from dynos and computers. I have really enjoyed this thread and feel in some part like I walked down the road with you through your words and pictures (luckily I didn't have to foot any of the bill and open my vitual wallet either 
) You've spent a lot of time on here when a lot of people would have ended the reports and updates, so again, thank you for taking us on this awesome journey! Keep the pix and posts coming, now they get to be pix of the car going through sweepers or it's unloading at Thunder Hill or coming down the famed Corkscrew at Laguna Seca! I've really enjoyed this thread and followed it from day 1. Thanks again, it's been a long "Three months"
