I'm not sure if any sarcasm was intended with this comment so I apologize if my response seems inappropriate.

Efficient turbo set-ups, especially turbine priority designs, are difficult to wastegate, PERIOD. I think if we were to add a few u-bends to the 4 exhaust runners or a 90 degree bend at the front of the downpipe we would have better control of the boost. However, doing these things will hurt power and boost response..... things which are way more important to us.

Look closely at the exhaust flow path on our turbo manifold to turbo to downpipe and you'll understand that there is an inevitable challenge to wastegating. However, this is a compromise we're willing to make in the name of power, etc. Furthermore, I honestly don't know why anyone would want to tune for less than 12 psi with our turbo system anyways, and that includes boost by gear. If we were dealing with a traction limited FWD car, then my thoughts would be different.

holding 12-13psi steady is all good for me!
Cant wait!

 

Just say the word and I will ship it to you.

 

how much does the oil cooler help? Im guessing its mostly needed if people plan on tracking with the setup?

and.... when will these kits ship??? i can't wait to for my buddy to send me pics of what they look like so i have some fap material for over here

 

For the AP1 guys, we'll be installing and dynoing an AP1 here shortly and will have more data for you (thanks Sean).

No Toan, thank you for this amazing kit and all of the wonderful customer service

 

+1 on Excellent customer service. Toan and the PTuning crew have provided top notch customer service. From answering questions, keeping me updated, and providing good front desk service. I am extremely pleased with the service.

Stay tuned for track testing information/pictures/video.

 

Extremely interested in your results. Would be nice to have a reliable turbo option for track use.

 

if Jasons car performs anything like my car did in damn near 100 degree weather and temps not even flinch, then this is definitely going to be a great option.

Track happy s2k:


Car performed extremely well on track today. Before the turbo kit passing other cars took time and a pedal flat to the floor. Now when passing cars it's rolling on the throttle and quickly manuevering around them.

The last session of the day I pushed the car with wide open track and reached max oil temperature of 226*F and coolant temperature of 190*F. This is with the oil cooler, SPAL fan (included with kit) and stock radiator. The system worked beautifully and performed as it should.

Stay tuned for track footage tomorrow. I left the camera mount in my garage today

 

That's awesome to hear a plug and play kit worthy of track abuse without any issues. How long is the track?
