Looking good... I still can't believe you are having such luck with those F18 gearboxes handling that amount of torque. My D20's must have been made with glass gears lol

Quite an interesting setup, why did you decide to put surge ports on your compressor ? Benzino is right, it was mostly for the sound improvement (I like loud turbos). But I was also hearing some occasional surge at low RPMs and considering there are no compressor maps for the CT12 this was a nice f...

Yes I would be interested to see that when you get a chance. As for the conversation, I would like it to remain here - but you can make a breakout thread with a copy of all the relevant posts if you want, as it might make it easier for people to read / search. Perhaps all the posts from the "dyno re...

If Im not mistaken, the ratio at idle should be around 2:1 with the WG closed and BOV open and move to 1:1 or lower with WG open and BOV closed at WOT. Just something further to consider.... you won't be able to measure any tangible pre-turbine exhaust pressure at idle. If you have backpressure at ...

Wow that sucks... I found the timing belt system/tensioner to be a little strange on these motors, but eventually got it right in my garage. And as Daniel mentioned, he should have turned the motor over by hand several times to verify everything.

so the reading was taken before the turbine? wouldn't that affect the reading? I thought you were meant to take it from after the turbo The type of 'back-pressure' talked about through most forum does refer to post turbine resriction. Like a dam in a river it restricts the free flowing ability of t...

Sounds awesome. Love the extra spool noise. That seems like a shit load of exhaust backpressure though... where was the reading taken from? thanks man! The reading was taken right at the turbine inlet (made a tiny bung right in the collector). The pressure does get excessive at my high boost settin...

As promised, here are some dyno clips:

Finally got this little badass setup tuned, and I'm quite happy with the results. http://s18.postimage.org/wcorssq8l/IMG_4915.jpg Despite the turbo being undersized for 2.0L we managed to squeeze out: 214 whp / 207 lb ft . http://s18.postimage.org/lbtmnrxzp/214whp_big.png Through progressive boost t...

Here's some pics of the fuel system setup... I have switched my 2 additional injectors over to Siemens Deka 63 lb/hr as they are supposed to have one of the widest spray patterns which is well suited for the throttle body type injection they are being used for. We also tried to run as much hardline ...

Here we have the new external gate welded on along with a slip fit recirculated dump tube... Also if you look closely, you will see that we ported the compressor cover for anti surge and increased turbo spooling sound ;) http://s13.postimage.org/ujtte9sqr/IMG_4884.jpg http://s13.postimage.org/pwj5yr...

Looking nice there, excited to see the progress

Upgrades are in progress now - pictures will be coming soon

Wow nice progress so far! Is that last picture your car with the old setup?

Hoping to get started on this soon.... I've got the parts that I need :D Another Used AVCR for progressive boost control ;) http://s12.postimage.org/onbzl6xd5/IMG_4822.jpg A friend hooked me up with this, after his project outgrew it lol. I must have return system to run any more than 8-10psi. Yes I...
