Jyrki drove to runner up position at Motopark Spring Nationals yesterday. We lost both turbos after three qualification rounds on saturday and had to take them off and continued. Jyrkis 0.01 reaction time put us to number two position after qualification and then we set our index to 11.99 and that caused focusing problems to our competitors  . So, good weekend, but expensive... Pics and vids will come later.

What happened to the turbos that you lost both at the same time? Great job changing back to natural asperation and driving to runner-up.

It seems to be that turbos did not get enough or at all oiling. When we put the engine together, we tested oil feed by cranking the engine with hose end of the turbos in canisters and oil feed was good. But after the failure turbos seem to be dry. Turbos are now sent to service and we sure hope they can fix them. Bearings to both, axle and wheels to right one and possibly axle to the left one. Six weeks to next race and we really want to go faster than 11.95 then... We are thinking about external oil pump to feed the turbos.

11,95 is quite good with 292 cid, ~8.5 cr and small exhaust outlets, I think.

Engine is now back together again and today was the time to do some fine tuning. And we did it for the fun of our neighbours again ! Here is the proof...

Alan, that garage wear was there for a purpose . Last time we did the same, exhaust pulses made a huge dust cloud out of a dry sand and that was a no no with open turbos .

So the idle advance is about 10 degree, max at 3000 rpm is 40 if running without boost. When hitting that 1.5 bar/22 psi, advance is 20 at 3000 rpm. Those numbers are not a dyno proven, so those are results of hunch of team's brainstorm aided by more badass turboracers. So if anybody got more ideas to this soup of speculations, feel free to leave a comment.

Great job guys. Congratulations!!One possible issue?
Many years ago I worked at Garrett AiResearch. I assume you have check valves in the turbo oil feed lines at the lowest point to avoid oil drain back? This was an issue on the first Offy turbo engines built for Indy in the 1960's; we had bearing failures that occurred on restarts with hot oil. This engine too had turbos mounted high up. Some engine builders also use an accumulator or auxiliary electric oil pump as well.

Good info WLJ. Thanks. In fact we have no check valves and that have not even came to my mind . But, this is learning all the time...

Thumbs up for the weekend. Tomorrow is first qualification day, saturday is another qualification day and then hopefully we will be in sundays eliminations too. I'm quite positive that we will go faster than 8.723 this weekend  . But, there is always a chance for rain to ruin our weekend...

We lost today on the second elimination round as Jyrki broke his 9.01 dial in by 8.885 / 226 km/h run with 1.217 60 ft time. We struggeled all weekend with fuel and ignition maps and last run on saturday and first run on sunday went badly due poor and slippery track conditions after someone oiled the track. Here is the list of runs:
R/T -.003 60 ft 1.487 ET 9.467 speed 227.62 km/h
-.018 1.245 9.126 224.94
.039 1.337 9.616 216.43
.046 1.258 9.226 224.03
-.024 1.309 9.037 232.15
.039 1.353 9.281 223.65
.090 1.350 9.832 213.25 one boost pressure hose got loose and sliding on slippery track. Won this as other guy red lighted.
.406 1.217 8.885 226.17 lost due break out
So, not the weekend we wanted, but the car is still in one piece and it's good to go to next race on next thursday to sunday  . We just have to get more ignition advance with 1.5 bar of boost to gain some more trap speed...

No casualties but Seppo and Jykä might have a mighty headache in tomorrow morning.I dont wanna spoil the official catastrophe report but there might be a couple of big holes in side of the block.

Jeah... One exhaust valve broke and then the piston and rod came through the wall... So, we lost a cylinder! Totally . That was in qualification run number three on Thursday and in about 1000ft. 6400 rpm and 1.55 bar of boost. Main reason is suspected to be too soft valve springs with boost. So, Jyrki and I have been trying to be just a little drunk ever since that happened... Two more days to go and then back home collecting money to build a new bottom end.

Ditto on Charlies WOW! If you keep breaking them like that we'll have to put you in touch with Pat in Texas. He splits the blocks completley. Somehow I don't expect you to find much useable out of that one. Good luck though. I hope this dosen't put you off racing. It is an expensive hobby though. Chuck

Looks like camshaft and lifters are ok and pushrods and roller rockers too. Crankshaft has to be measured and possibly #1 and #5 rod journal have to be grind to undersize 2.100. Other journals might be ok with only polishing. So, we only need one block machined, heads fitted with larger valves, one new piston and two connecting rods to build a new engine. And oil pump and shaft  ...

We were preparing our dragster today for the next event on coming saturday and with Jyrki's old normally aspirated engine. Some problems occurred during the cam break in as the distributor gear pin was broken and we didn't realize that before the engine warmed up and started running badly. The gear spinned over the axle and ignition advance got screwed! That breakage happened at the last race where our turbo engine destroyed.
http://www.youtube.com/watch?v=WvGmUd4mQns&feature=c4-overview&list=UUxZ94DRcBfpz0DstGIV1_QA
So, tomorrow we will install a new pin and do some more tuning and then go for the hunt of high 10's or low 11's .

16 ladder elimination today and Jyrki took a red light at semi final and we lost to Janne Noren's Chevy powered '34 Ford! 11.859 / 175,69 was best the normally aspirated Y could do with non ported heads and about 10.4 to 1 compression. Seven runs this weekend and three 0.001 sec reactions. All runs in 11.859 to 12.004 range and all top speeds within 173 to 176 km/h! One race weekend to go this year...

And a short video about one 11.9 second run. Doesn't even lift the wheel without turbos . And that steering does some strange moves when turning... Whoops! 60 ft times were around 1.6 seconds.

That is a huge turbo sticking out of the orange chevyII, and does the blue mopar run 8.0's, Nice looking top quality cars. Looks like it was quite a show. Hope you get your turbo engine back together soon. Any plans to get the kids a JR dragster?

Sorry to hear that Hollow heads lost their engine block.. However, have followed their exploits here & in Y-Block magazine for some time. Sorry, but I'm not surprised, as I think they have been expecting to much. This is a case of to much Turbo charging & not enough time & money spent on the engine under the turbos...
|
|
By MoonShadow - 11 Years Ago
|
I'm not sure what they did to the bottom end but it was pretty stout. If it didn't have a girdle and reworked caps/bolts it probably will soon. They are far below their fastest, more is yet to come.
Are you following the super horsepower twin turbo pickup on the forum? I'm still waiting for it to over test its bottom end. Chuck
|
|
By Hollow Head - 11 Years Ago
|
Paul, you are right about money spent. With more money and time we could have gone to dyno more often, but it takes 500 euros each time.
Chuck, you are right about that bottom end. It really is stout and can handle a lot torque and horsepower if balanced right. Even with stock bolts. Don't remember if Hutz is using ARP stud in his engine, but we had stocks. And that our mishap did'n come from bottom end...
And, about our expectations... Sure, we expect a lot but we still are sure we will do it. It's just to get all things together and working right. Going fast isn't easy or cheap, but it's fun! Is there really any point to stick with carbs and without boost .

Since the failure was caused by a broken valve..the question is, was it a used stock valve? And, what kind of valve springs were used? Are the valve keepers original factory etc? Ford only recommended a max of 5400 rpm for the standard stock component valve train. On the Dyno tests, was there indication of valve float ? All questions that need to be answered to avoid a nasty repeat episode..
|

By Hollow Head - 11 Years Ago

Ferrea stainless steel 1.84 intakes and 1.70 exhausts. Comp Cams 942-16 springs without damper coils as they did't fit with non massaged guide bosses . Comp Cams retainers and locks. So, that exhaust valve broke simply because of too soft spring set up and valve beeing too large diameter for our stock bore size and hitting the corner of the cylinder wall. Nothing secret here, just old stupidity. Also, Harland Sharp 1.6 roller rockers helped lifting the valve too far... And causing several bend push rods. Push rod cup end breakings were caused by too wide ball ends as discussed in different topic earlier. So, we are learning the hard way and piece by piece, but be sure our next engine will be even more aggressive and records will be broken. If not the WR, atleast our own. We will double our injector size as now used duty cycles show that we don't have enough fuel flow with E85 and 1.5 bar of boost. And something else too . Visiting the dyno with time and money collected during the winter time...

One thing about learning the hard way, you will not make those mistakes again. Not only is it expensive, but you don't get to race when your car is broke. I think your group has come a long ways from the hot rod. Keep the Faith, baby!

Way to go guys, and to think that I was a witness to the original "Hollow Heads" engine firing up for the first time. Everyone keeps coaxing more horsepower and lower ETs out of our old powerplants. Would love to see you guys at Columbus! I just bet that someone would stick you in a car!

Jim, funny that you mentioned our Hollow Machine engine. We just sold that one to our friend in Tampere and it will power one customized '53 Ford that was originally four door sedan and it is now two door chopped custom. Time flies, but I doubt that we come to Columbus this year. We are afraid to be put to stick cars with carbs . Would be funny though, to see all you there...

Considering your short summer you should get something like that going over there. I'm sure you already have ice races. Just have to get them to straighten the track a bit. Does look like winter fun. Chuck
|
|
By Hollow Head - 11 Years Ago
|
Chuck, indeed we have ice races but on past five to ten years all races here in southern Finland have been cancelled due too thin or at all ice on the lakes. Even the motorcycle races have been cancelled as tractors would have gone through ice when clearing the track. And also the "green" peoples have caused problems and most of the southern lakes are not allowed even for boats with motors and so cars over the ice are also a no no! Soon they propably will cancel all skiing on ice and snow as the ski waxes dirt the earth...
But, we still have some nice things going on... LSR racing on ice!
