Six runs during final round of Finnish Drag Race Championships in Motopark raceway and engine is still in one piece. Lost in third round of 32 car ladder. Good news is that all runs were under nine seconds and best was 8.644 and it is now new European Record! And as a back up 8.660 is also good one. Also our best top speed is now 245,49 km/h. Previous best was 243 km/h. 2 kilos of boost is NICE! 8.845 / 245,49 8.674 / 231,89 8.660 / 238,42 8.661 / 244,25 8.644 / 245,03 8.715 / 245,03 !!!

Hollow Head (8/17/2014) Six runs during final round of Finnish Drag Race Championships in Motopark raceway and engine is still in one piece. Lost in third round of 32 car ladder. Good news is that all runs were under nine seconds and best was 8.644 and it is now new European Record! And as a back up 8.660 is also good one. Also our best top speed is now 245,49 km/h. Previous best was 243 km/h. 2 kilos of boost is NICE! 8.845 / 245,49 8.674 / 231,89 8.660 / 238,42 8.661 / 244,25 8.644 / 245,03 8.715 / 245,03 !!! That’s an excellent run of numbers and it’s good to see the car going rounds with fewer issues. For awhile I thought you might let me slip back into the #3 all time quickest slot with my current combination. You have definitely lowered the mark to the point that it will take some serious work to just get to where you are now. Good job guys.

Hollow Head (8/17/2014)
8.845 / 245,49 8.674 / 231,89 8.660 / 238,42 8.661 / 244,25 8.644 / 245,03 8.715 / 245,03 !!!
8.660 is made with 1.93 Bar / 28PSI of boost but when fuel pressure was too low, air/fuel ratio was too lean before finish line. Then we rised pressure and the moment before finish line was too rich so boost didnt rise enough, only 1.6 Bar / 23 PSI but there was still more power than before. Then came the Elimination day and tuning the engine to get more power in E.T. class is quite stupid thing to do, so we dint lean the engine enough to find the sweet spot.
There is still more power in reserve beneath the 2 Bar line. How much, I dont know but I hope we will find it after the winter hibernation. Engine goes maybe a little bit too rich in whole quarter mile and the end is way too rich. Then there is ignition advance what isn't dyno proofed so there might be some loose horses too.
