I have no idea. I'm actually using a w110 now though.

So I had completely forgotten about it but recently it has come to my mind that I have not figured out the cc of the combustion chambers. I didn't really know how to so I searched it up and found this video.

Is it necessary to buy a kit for this or is there any other way? And also, does it matter what kind of fluid I use? I guess it has to be thick enough that it doesn't leak around the "cap" piece. And what do I need to know this info for? I'm just confused in general about compression ratio and chamber cc's so any help is appreciated!

You can "bodgy" it by using an old CD and a syringe if you don't want the kit, just seal the disc to the head with some vaseline and fill through the hole.

Many people try to use a fluid with lower suface tension, but plain old water will get you there also.

Once you have done your measurments, put your figures into the attached link and find what static CR you have

I just got done checking the chamber cc's and it looks like they're all around 70. I guess that's the difference of hemi heads, huh? So I put it in the calculator and figure that with a deck height of 0.04" it'll be around 7.2:1. That's pretty low, isn't it?

Mon Jan 09, 2012 10:36 pm

Help?

Mon Jan 09, 2012 10:54 pm

Yes thats pretty low, Gene Berg would be proud, time to flycut

Is such low compression bad? And what is flycutting? I thought they were already flycut?

Tue Jan 10, 2012 5:05 pm

Its not bad but you won't get the performance you want out of it, flycutting will reduce the combustion chamber volume increasing the static compression ratio.

Tue Jan 10, 2012 6:03 pm

So what does flycutting involve?

:lol: I'm a Berg fan and that's funny!

Flycutting, anyone? What do I need to do and what is involved in it?

Well guys, it's been a loooooooooong time coming but I have decided to take all my parts to a local guy that builds engines for everyone in the local VW club. He doesn't mind if I'm there helping and learning, so I'll know how to do it for next time! Soon I may have my 1915 :D

Tue Feb 28, 2012 10:35 pm

Okay this may be a stupid question, but... do I need to use washers when bolting the gear to the cam? :oops:

Tue Feb 28, 2012 10:39 pm

Normally yes

Wed Feb 29, 2012 1:04 am

If you use flanged type bolts, or at least bolts with a good sized head to spread out the load, then no washer is needed

Thanks guys!

Okay took the parts to the builder today, forgot the heads at home, stayed too long talking, and was 25 minutes late for class! While I was there talking, he pointed out that my block doesn't have a hole in it for a mechanical fuel pump. I hadn't even realized that! So will any old electric fuel pump work or should I get some certain one? Keep in mind that I don't want to break the bank.

If you are still using the webers, a lot of people are using the carter rotary pumps, they are internally regulated to 3-3.5 psi, CB Performance sells em but you can usually get them cheaper if you don't mind hunting around

Is this it? http://autoplicity.com/products/1287010-Carter_P46...SNOFITMENT

I looked on cbperformance.com but the only electric fuel pump i found was this. http://cbperformance.com/catalog.asp?ProductID=577

And then what about this one? http://vwparts.aircooled.net/Facet-Electric-Fuel-Pump-3psi-p/1008.htm

Thu Mar 01, 2012 9:36 pm

the CB one goes "whrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr"
the facet goes "click click click........click............................click......."

Which sound effect would you prefer?

Thu Mar 01, 2012 9:40 pm

The one I was talking about is CB part no. 3193, the facet ones work well also but can be quite noisy unless mounted with isolation blocks
