2.0T upgrade program part 3: 400 BARRIER CROSSED!Between part 2 and part 3 we posted an onboard acceleration video of the new setup. Because, claiming 400+ hp is one thing, but actually showing it is something else. With almost 200k views, the video got its attention and comments. We want to show you the data in this post.To recap, we started with a stock Giulia Veloce 2.0T, did the Squadra Tuning software and got ~310 hp and 470 Nm. Later we added our 2263 hybrid turbo, secondary heat exchanger for the LT (intercooling) water circuit, downpipe with 200 cell cat, Ragazzon 3” valved rear muffler and 3” centre pipe. ECU and TCU were updated with the Squadra stage 3 programs, which resulted in a ~365 hp and 490 Nm.Apart from the performance upgrade parts we placed the following instrumentation from Banks Power:- Idash datamonster- Air mouse- Thermocouple module - Analog moduleWith this we are able to log EGT, EMP scroll 1, EMP scroll 2, Post turbo exhaust pressure and several others important parameters. Also for fun we added the Banks Pedal monster.In addition we are using the Squadra Performance logger that can capture a lot of valuable ECU data together with a precise power and torque calculation. All this data combined tells a lot of the engine performance and shows which mods make sense and which doesn’t. Ofcourse we wanted to achieve more power than the 360-370 hp almost everybody is making with hybrid turbos, and over the years we figured out that the limitation must have been in the exhaust housing, we just couldn’t validate it until recently. Data from the banks instrumentation showed high turbine inlet pressure, especially in one scroll that resulted in a power ceiling. When we replaced the complete turbo with a full frame monoscroll unit the turbine inlet pressure decreased with 0.5 bar (and that resulted in an immediate power increase of ~40 hp on the same tune! What changes is the cylinder scavenge ratio, and Banks Power made a great representation of this Idash parameter that we’ve borrowed to fill in our numbers. A 13.6% percent improvement in pressure balance led to a 11.4% increase in power output as seen in the picture below. Looking at the power and torque graphs we notice the torque curve shifted around 500 rpm to higher rpm, but from 4000 rpm onwards instead of tapering down, it increases and it remains higher all the way up to the rev limiter. As a result, the maximum power of 412 hp is now achieved around 6300 rpm and still at 400+ at 6600 rpm where we had the limiter set. In reality, the torque loss at low rpm does not affect driveability, and the stronger top end really makes the car pull hard until the end.As of now, we’re not finished as some areas still aren’t optimal. With the planned mods in place we hope to hit 420 hp which isn’t too far away. Stay tuned!
The webshop is now live again, after the PHP safety breach was fixed last evening.Also we’re back from holiday so order processing will restart today.
