First dyno with new turbo was super disappointing. Car produced bit under 300hp and bit over 400Nm of torque which means that Gt28R produced only under 15hp more and over 50Nm less than my old K03 Hybrid.
Something is not right.
Trackday catastrophe first fan cut the lower radiator hose. After that was fixed couple laps on the track power steering started to make some noise. Now it sounds like angle grinder and have to drive 100km to home.
And there's also some where small leak of around the turbo.
Trackday with new setup, still minor problems to solve. Like why not enough power, did powersteering pump give up or not. Now powersteering fluids seems to stay where they should, leaking was from the oil feed line.

Extra fuelpump to ease the fuel supply. Trying to keep everything "stock" look.

Couple weeks ago we did small ecu tuning and got ~30-40Nm more torque with lower boost settings but there's still some bottle neck in the system. Something very stranges because we cannon't get car boosting over 1.7bar even port closed. Also boost hose before FMIC tries to pop off time to time. We have started to suspect that there's problem with the FMIC. SeatSport oem FMIC do not flow enough or that at some point of rebuild I have for got some damn rag in the boost pipe. Last night I tested if I can get something out of the intercooler by pushing air in to it but it didn't help.
Also I have asked new even bigger turbo for the car, so most likely I will buy at some point new Garrett GTX2871r and start to drive with E85
I just want to say your tune is fantastic, It wont be overly exciting however thats the perfect tune for a track car, you don't want a huge surge and drop off, a nice linear path is fantastic.
Great work, beautiful car!
Some updates planed already. New exhaust manifold is in order and most likely I will upgrade GT28R (GT2560r) to those new GTX serie turbos. Also got software changer so next summer I can run with 3 different softwares. Possible street software for gasoline and E85 and race software with E85
I has been while when I have updated anything. Basically I haven't done almost anything for the car. GF bought house so we have been renovating it. And rest of the time I have spend at work or doing/studying one WRC RX car.
Bedroom renovation in progress
Some handigrafted pillars for reinforcement, Old wall was removed at somepoint of history and need some supports. This was my vision of it. 6x6" Timber and lots of time
What I have done with cars I have bought new manifold for Leon
And tried to do some ECU stuff for my friends project (desolder eprom, read it, modify it, write it and solder back to motronic 3.8.3)
Finally decided what turbo I will have and ordered that right a way. week or two I will have GTX2867R Gen 2 and have to start again taking Leon to parts.
