Well Dyno Day came around much quicker that I expected and after spending 10 hours the day before servicing and prepping the car I loaded the car on to the transported with only two goals for the day. First, I wanted the can to have a good shake down and to see if the engine mounts I had made and welded in would hold the engine in place and not fail. The second goal was to be able to drive the car out of the dyno and start getting it ready for its first MOT since August 2016 and finally I wanted to make a little bit of power, I had a goal of 335 hp.
So how did the day go?
I think badly I think sums the day It wasn’t terrible I met both of my goals. On the first run up and checks the car made 7hp and reached a coolant temp of 117 C.
So clearly there was a problem, after a little searching I found a kink in the hose going to the rad. A few days before I decided to change the coolant pipe set up because I had to many connectors and they were rubbing, so after changing it it seems I did not see the kink I had caused. Solving this little problem took a few hours as there was no way of not having a kink in the pipe. The guys at emerald were fantastic they found some mild steel pipe 25mm opposed to the 28mm I was using, bent it to shape, found some clip and we solved the coolant issue, however in my rush I damaged the starter solenoid wire, and the car would not start and while an easy fix it still took time to find the fault and fix it.
So after a few hours the car was back on the dyno ready to go, and this time it made a 40hp, before it developed a misfire so a check of all the wiring turned up nothing, so the spark plugs were pulled out and I don’t know how but 3 of the 4 ceramic casing were cracked. These were gapped and quickly swapped out and now the car made 69hp on the next run. From this point the mapping of the base map went well until the car stopped making boost, so again working over the hot engine a search found that the turbo to the intercooler pipe had worked loose, most likely when I was working on the hose and starter wire. A quick fix and off we go again, the car was responding well, the coolant temp was stable at 98C, and the car started to make boost 5-6psi so things were looking up until a huge back fire and the car started acting like it had ran out of fuel. So again, another search and the OEM temp sensor had fallen out, so the car was getting too much air and not a lack of fuel.
After the days events the base map was finished and with 5-6psi of boost the car made 197hp, now as we start rolling in the boost nothing happens the boost does not go up not matter what we do to the boost controller so at this point I decide that even if I fix the problem I would only get a max of 10-12psi, which is not ideal so I decide to end the session (it was 5.30pm) and go away and resolve all the issues before going for more power.
The car is booked into Emerald again on the 22nd of October and the goal is to drive the car up to the session make my 300+hp goal and drive home.
