Wow, I have some progress to report on the Timebandit.... 

The body is still in primer and is waiting for the pre paint mock up... by the look of things it can take some time. But on the other hand I have made some good progress on the engine for the car. The CE heads have had a running with the mill and is now down to 47 cc in the combustion chambers. The chambers themselves have been reworked by me and is strangely uniform in shape and volume. The valve pockets in my pistons adds another 5 cc to the equation, with 1 mm of deck-height, that leaves me with a low 10.2 CR. With my FK89 Im looking for something around 11.3.  So my heads will need another go in the mill before Im happy with them.

I have had about two weeks of vacation now and I have really enjoys the late hours I have spent working on the engine. Opening up new parts and finding them to be within specs brings a smile to my face. However I admit getting a "tad" frustrated with my new CB straight cut kit... I had five full blown attempts to mount it on the crank without getting it on....  THEN i measured the slot for the woodruff key....  0.5 mm to narrow! Out came the file... and the KEY went under surgery since the gear was way to hard to modify. I have also had some great fun dialing in the new FK89... was happy to find that cam card and reality match.

Oh and I took a hack saw to a pair of intakes... loving the results!!! 

I hope to have the engine up and running in time to SCC this fall....  Maybe I get to try it on the strip to... if the makeshift "race-car" gets thru the scrutinizing of the tech guys....

There has been a Bad Batch Of CB Straight cut Gears they are very Thight and I have Seen Three Different sets with the small gear cracking two cracked after the motor were run and had to be torn Down..

[Jon]

Okay, thanks... I didn´t know..... I dont expect mine to crack as it was close to the VW size in the hole (it was a little tighter) but the grove was WAY off!
Fingers crossed! :-)

[Jon]

Well, CB won over me again it seems... the crank lifts the cam up...   back to square one... out with the new and in with the old!

[Shubee2 (DSK)]

LOL  just put a set of Magnum gears in it  you will be glad you did sell the CB ones on Samba

[quickkafer]

Glad to hear it's coming along!

I spent ALL day yesterday with some friends getting my make shift racer up and running (with a 1600).  And today
I got the electrics to work and did a bit of break adjusting... and as by magic got the car thru MOT!!
It still need a of of work, but the basics are there... except the shifting... quite frankly it SUCKS even tho it has the daddy of all shifters... the BERG.

O happy days.. I got a bug to cruise in!!   

[Jon]

The shifter problems were dealt with tonight... out came the angle grinder, the worn out bushing holder was repaired and the whole lot went in again.... but 100mm further back... ups!! 

[Grelland]

pics?

[Jon]

You will see it live today Grelland!
The heads went under the knife again last night... it bounced up from 11.1 to 11.6...  Will it still run on Shell V-Max...? I don't know!?

I did the same thing last night even though I kept everything where it`s supposed to be  SCC..... I`m one small step closer!

Keep on with the good work JHU!

[Jon]

If every other method fails we can then distinguish our cars by the placing of the shifter.... mine is a 65 too you know?

Can't wait :-) The sun is shining, see you later

Well the engine is alive now....!! Took me some sweet time!! And the sound of it isn't what I expected. I have never heard any of my engines without the fatty stinger... but this one breathes thru a 2,5" Apple racing muffler... so the sound is all civilized... And It will stay that way for a couple of days more, as I welded in the bung for the LM1 Broadband lambda in the muffler side of the collector. As soon as I get home from work, I'm going to run sync the carbs and let it run for 5 minutes, then I’m dropping the oil, fit my temp sensor in the universal case block of. Fill up on cheap oil and find a good hill to get the rings to set. After that the synthetic SAE 40 will go back in. This is going to be a good night.

coming over to Bitburg jon?

[Jon]

No not this year...

Jon, i'm thinking about an Apple muffler too. Quiet? ,Restrictive ?

[Rune]

I have a short video clip of a friends car running an apple muffler, but I don't know how to put it out here. Very special sound, sharp and crisp. But at the same time nice and quiet on low revs. I think it is very free flowing as well.. 

[Harry/FDK]

Thanks Rune, i need something for the center of town (cops) Then WOT

[Jon]

I wouldn't say its quiet, but its muffeled. Just a deep dark rumble, it has a more muffeled sound than your average "fatboy". Probably due to the size of the thing.
But you hear it when you step on it....

Well, I drove my engine for the first time last night. And I have to say it was interesting   
The task at hand was to get the rings set and to do a bit of jetting. I used my LM wideband and was happy to see it being on the rich side.
Started out with 60 idle jets and 180 Main with 200 air. In F2 emulsion tubes. The ignition was set to 32°.
I had a serious stumble between idle and main and I also experienced some pinging in around the same RPM 3000 ish. I stopped and backed of the ignition 5 ° but still there was pinging in this transition.
And suddenly the oil temp was out of control, and I stopped to cool it of. I Suspected had misunderstood the Lambda readings and put in 70 idle jets and 195 mains.
Then I realized the oil temp gauge had made contact with ground, so I got that fixed and the temp fell down to 50°C puh.
But more interestingly the car was running EVEN richer (no big surprise) but the stumble had diminished severely and the pinging was also gone.

After a few pulls up a steep hill I decided to go home and think about my next action. I found out that my float levels still was to high and the fuel was dripping down into 3 and 1.
So I pulled the carbs and the intakes to mount a set of borrowed 51,5's to it. Might as well tune it in with those carbs, since my 48’s are a bit on the small side for this setup.

But my question is could my F2 emulsion tubes be the reason behind the stumble? I have a set of F9 and a set of F7's to, will test the F9s today to see how it acts.
Any ideas?

[richie]

i know very little about IDAS but they always seem to end up with F7s,just my experience,cheers richie,uk

Jon, did you drop the Synthetic in right after the break-in

[Jon]

I used cheap mineral from a chain that re-brands everything they sell, so I thought it was shit, but later I found out its Statoil 10-40 and was gutted.
After I was sure the rings had set I poured in Valvoline synthetic. I also had a chance to look at my lifters (stock VW's) and they seem fine, even though the K800s are sitting with 200psi in the seats. So I'm sticking to my "lifter-jumping-on-cam-kills-the-fun" belief... for now

[Harry/FDK]

That's still a quick move from mineral to synth...

[nicolas]

do you need to have a breakin time on mineral before switching to synthetic? i want to use synth oil in the future, but i may need some help regarding the subject... sorry to jump on your post.

[Jon]

Synthetic oil has superior lubricating capabilities and will not let your piston rings wear in (fit to the sylinder) as fast as dino oil.
I used Synthetic oil during the breaking in of the cam, since that is a case of work harding the cam and not a "wear in" issue.

Then I used mineral to set the rings, and back to synthetic before the dino stuff got the engine all dirty inside.
I set the rings by this method: http://www.mototuneusa.com/break_in_secrets.htm But I don't recommend it to others. People can chose for themselves.   

Harry, what do you mean with "quick change"?

What do you mean? Is there any other ways to break in a the rings           Breaking in the rings is the fun part

Very interesting view of breaking an engine in under full throttle, but in a way it makes sense that the pressure forces the rings to lay on the cylinder.But what is with total seals ?
It`s funny cause I came across this theme of the pressure forcing the rings to the cylinder with a friend as we talked over the need of total seals.
But we didn`t think about the break in...

By the way, very nice progress and the vids of your hill racer were so GO(O)D ! Go on and on...
