Columbus would be nice but we need a big sponsor for that and finnish Y-block racing part markets are quite small in today.

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.

Ted, I'm sure you will cut couple of tenths off of your times, so you will give us good pressure with your stroker motor. We really should have gone a lot faster this year, but maybe this "one tick at a time" approach with turbo screw is wiser than that 2012 " hmmm.... half a turn ain't gonna hurt anything" method  . By the way, how much stall do you have and what is your rear end ratio? Maybe we have to lower a little our gears from 4.29 to 4.11 to get some more top speed...?

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.

I’m currently running 4.30 rear gears but considering switching to 4.44's or 4.56’s. I’ll not be doing any gear changes until later in the year though when the temperatures are cooler.

Interesting... We have 33 x 14.5 - 15 tyres and we are suffering lack of speed and revs as we have only 7200 rpm at the finish line due home ported C0AE heads. That's why I consider gear change as an option to get more speed, if our engine makes power enough to launch it hard with lower gears. So, as I assume, your engine revs much higher at the end, what is your point to get more gears? Our 60 feets are almost equal, but we have issues with bouncing and slipping. http://ammikanala.kuvat.fi/#/kuvat/Auto+siellä,+toinen+täällä/Blaklader+Finals,+part+II/_MG_4344.JPG

Interesting... ..... So, as I assume, your engine revs much higher at the end, what is your point to get more gears? Our 60 feets are almost equal, but we have issues with bouncing and slipping. I run two different sets of tires and wheels; a set of wider and shorter tires for normal bracket racing and a narrower set with much narrower wheels for ‘quicker’ runs. The narrower set of wheels allows the tires to grow another 3-4” in diameter which helps the topend charge. My rpms going through the traps are in the 6600-6700 rpm range. It’s because I do have some rpms left at the top end of the track that I’m considering more rear gear. Converter slippage is minimal in my case also which may be a player in your combination.
