So, Jyrki (yfreak57) is now first ever certified Y-block drag racer here in Finland. He drove five license runs at 5th round of Finnish Championship series race at Motopark track. Runs were not extremely good, thus we had problems with trans brake in all runs. Overflow cans water hose got loose on one run and sprayed Jyrkis helmet and he had to lift. On one run, little amount of oil came up from dipstick tube and he lifted on that one too. Then he hassled badly one run after he had to wait over half an hour at the water pot because former driver oiled 660 ft of another track and they had to clean it. At the last run we raised boost pressure a little to 14 psi and due that or that earlier mentioned water problem and overheating, we blowed the head gasket and number one filled up with water. We found that out right when we tried to go to run number 6, but water was dripping from under exhaust manifold. Then we pulled the plug from #1 and thats it. Race was over, because we went there to race, not to wrench  . We had no spares along and you know, here in Finland it's little hard to find Y-block gaskets from another drivers  . But, we made a new Finnish Y-block Record by 11.818s and 187 km/h. Car really has potential to lot better times, but we are still learning... And, what is good also, we got the car certified to 7,50 and slower times! Here is some pics anyway.

Nice pix! Sorry you had trouble but that's racing. Nice patch on the jacket.

Simo, absolutely not for that, but we did that too  . I'm still having a headache ...

More pix from Pro Photographer... 
I think that last one is the ONE that Jyrki screwed by making burn out without towers permission  . Starting line judge didn't like about that ! It can happen to rookies.

Here in the states we call that "new car blues". Happens to everyone. Do you have some type of pan evacuation system on the engine? That will help stop pushing the dip stick tube out, and help seal the rings. You guys have come a long way and will get everything sorted out i am sure. Great looking car.

Found some water... . 
Could be better open up the other side too?

I have never seen intake valves that look those.

Seppo: Yes, I would recommend you look at the other side. Did you run the engine through a few heat/cool cycles and retorque the heads before hitting it with boost? You should do that.

Seppo, Just out of curiosity, what are you using for head bolts/studs?

what are you using for head bolts/studs?Bolts are stock like almost all parts except water pump, intake, headers and valves...

I’m assuming you are running posted heads? Definitely switch the head bolts to a true grade eight bolt though. You might consider upgrading to a ½” head bolt also so that the head bolt torque values can be increased. Keep at it as you’ll eventually get the ‘new car’ bugs worked out.

Great job! Keep up the great work, Just shows Y's are still running hard round the globe.

You can get the bolts from Ted or John Mummert. Studs are available also. Ted do we, or could we get a picture article on posting the heads. Feistritzer uses bolts inserted thru the top and pushing against the deck on non-posted heads. But I doubt if he's ever photographed the process.

As a cure for the problem, we are just going to add more fuel to the fire! We just bought 75 lbs/hr injectors and those should be enough up to 1000 hp . Won't go to lean anymore... If that was a part of the problem. At the dyno years ago and until now we had 30 lbs/hr injectors and those were at the limit in that last 330 Hp/ 630 Nm pull with 5300 rpm limit. So, now that we had more revs and more boost, that may well have been one reason to that gasket failure. And that slight overheating and loose bolts were possibly other reasons. So, we will put it back again and readjust the shifter cable to get that trans brake working properly and then we just wait for the next outing. Or, we tear it all apart and start to make it to last longer with H- profile cons and forged pistons, main girdle and billet steel main caps and ARPs everywhere .

Try these two links for information regarding adding posts to heads that do not have them. If you already have posted heads, then just disregard this. http://www.y-blocksforever.com/forums/Topic47592-3-1.aspx http://www.y-blocksforever.com/forums/Topic33877-3-1.aspx

I wonder if we should have a "how to do it" section on the forum for articles like head posting etc. I know there is a tech section off the home page but people don't seem to find it. Just a thought Jim? Chuck in NH

Heads are C0AE, so they are posted. Question about ARP studs: What stud would be long enough to reach up to oil pan attaching level from main bolt holes and even ½ to 1 inch above the oil pan level to bolt main girdle between the block and the oil pan?

.......Question about ARP studs: What stud would be long enough to reach up to oil pan attaching level from main bolt holes and even ½ to 1 inch above the oil pan level to bolt main girdle between the block and the oil pan?For the main support girdles, I’m using studs and hardware found in the Granger catalog. They are coarse threaded on both ends. On these, there’s enough thread to torque the main caps down without the girdle in place and then with the proper spacers, lay the girdle on top of those nuts and then another set of nuts to hold the girdle in place. Double nutted when the assembly is in place. When cutting out the girdle, if you’ll leave some material in the girdle on the engines right side, you’ll incorporate some windage control into the girdle. Here’s a picture.

Jep, we are planning very similar set up, exept that we are going to fab new main caps tall enough to touch that girdle and then just bolt all together.

Ted, do you happen to have any girdles to sell or is it possible to make more of those. You sure have the drawings and it might be even cheaper to buy from you than discover the wheel again and manufacture those here in Finland .

Ted, I would also like to piggy back on these requests for a girdle. If we are going to step up the speed on these Y-Blocks (especially turbocharged), we need to do everything possible to hold them together for a WOT three mile ride.

I had a lot of trouble with my head gaskets blowing as you had probably read on my post. I did post my heads and used ARP head studs. I threw the torque spec out the window and toqued them to 120 lb/ft and then grabbed my breaker bar and cranked them down some more. I was tired of blowing head gaskets and thought they will either hold or I will the strip the threads out of the block. I am running 10 lbs of boost and so far they are holding together just fine. I love the block girdle. I am waiting for my 235 lb/hr injectors to show up so I can really crank this thing on the dyno. Good luck can't wait to see that thing roar down the track.
