I had to wait for the pistons to be made as they are 87.5mm
(5s is natively 87mm standard bore) so this took 6 weeks, I receievd them 3 weeks ago and had the block machined straight away.I also did some other alterations to the engine while I was on and I had some wiring alterations to make too.
I put the car back on the road last saturday and put 60 miles of light boost partial throttle driving on the engine, changed the oil out and put another 100 miles on, then on thursday drove 260 miles to the dyno, more mileage than i wanted on it before the dyno really but I will only have Ryan G map the car and its worth the drive.
We went for a safe map as we have a 2500mile trip to italy next month, and this session was mainly about making sure the engine stayed in one piece! It made 580hp
@ 1.5bar and at 1.8bar it was wheel spinning and we werent getting an acurate reading, Ryan took some timing out for longevity sake and estimated it around 600hp at 1.8barI have some other things I want to do and alter so will run it up to 2.2bar next year and get some solid figures for those who need to see graphs.
I had a 6 point cage welded in last year and put some 4 pots on the front, its on coilovers and usual other supporting mods but I wont bore everyone with a list.
Aside from the roll cage and machining of the engine parts I built this car myself completely.
