Finally got the 3.0 turbo right!
Well the dyno session is complete at the results are in...
The car ran faultlessly with rock solid intake temps never rising under boost and coolant temps were good as well. Really pleased with the way it has all come together, the custom front mount IC I designed has paid off as it is totally unfazed by anything I throw at it.
The results
401hp and just under 420lbft torque.
I have images of the dyno charts I will post shortly.
We spent lots of time on the drive ability doing road mapping after and also going the idle right which has bothered me for ages. I am now able to say that the car now runs like a factory car. You can drive it down to the shops and never know any different it's just like a standard 968 off boost, but wind it up and it takes off like a scalded cat! Very pleasing to drive.
I have Thoms old turbo installed - he went to GT30 as some of you will know. I didnt need the extra fab work for now, just wanted to get the car running so the bolt on option was good for me. I took off the old Vitesse Stage V (an old version), nothing against this turbo, it was great in the top end but just to laggy for the 968 box as the gears are shorter and it just doesnt get a chance to load up, at least it didnt on my car. Thoms turbo is much faster spooling and the car really comes alive with it on, there is a price to pay on the top end but I am happy with the figures. It is a street car and the low down torque combined with the 968 box works really well.
Thanks to those friends who have been through this with me for a while and helped with the r&d on these 3.0 conversions. Patrick, Thom, Duke & Tom in particular but the wealth of knowledge in these forums has in no small part helped me to complete this build. My car is as much 951 as it is 968 so it deserves a post here!

Congratulations Nick. The charts look good!
A lot has changed in turbos over the last 8-9 years, now start driving and really enjoying the car.

Thanks John. This is not a new turbo though, it was out together not much later than my old turbo. I know your new stage v performs a lot better though and agree things have moved on a lot. This turbo came up at the right time and was a good halfway point for me for now until I find the final solution that will hopefully give me the best of both worlds with less compromise.

Congrats Nick! Great to see all bits and pieces coming together with nice results!
As much as I enjoy over the top monster cars that hardly can idle right - a nice 951 or 968 with a refined turbo package with enough power and a civilized manner is just perfect for the street. Great job!
Oh and I would rate those 401 bhp as similar to 401 rwhp Dynojet.

Nick, that's great news after such a long and at times frustrating process. Congratulations for seeing through especially with all the other 'stuff' you've been dealing with. Dyno Dynamics tend to be pretty conservative compared to some other brands and going off the curves you have, the car looks very nice to drive with plenty of early torque and a very smooth hp curve. Plus this is all at modest boost levels. Looks like you will have many years of really satisfying motoring ahead and also plenty more power to be gained should you wind the wick up! Great to see. :-)
