DIY T-4 head volume CC kit, on the cheap Options

[rfinegan]

I put together some cheep pieces to make a CC kit
I got from amazon but I am sure it can bee done even cheaper> about 10 bucks per kit
FREE shipping too

just drill a hole, seal with petroleum jelly and use ATF or Colored washer fluid

I post a video of how I used it soon....

Burettes are more accurate but a bunch harder to use IMO.

When you're pushing 13-1 a cc of difference is a huge jump in static comp ratio.

When you're pushing 9-1 a cc doesn't do shit...

I drill the inlet so a hypo "sticks" in the hole and holds itself upright.

If you drill so the hypo tip just clears the other side you don't have to worry about the volume of that hole.
The breather hole should be so small as to be an insignificant volume change (especially at low compression ratios).

I use antifreeze as my CC fluid.

It has a super low surface tension and bubbles don't get trapped or created as easily.

And, because it has a low surface tension it will leak past the valve seats like nothing else in this world.

I combat this by smearing the contact point/valve seat with candle wax.

Anything that doesn't evaporate quickly will work, ATF is fine.

I've always used old school green antifreeze.

When you're blueprinting a motor and varying chamber volume to account for deck height/piston differences. you can end up doing this crap 4 or 5 times on a single chamber.

This is more critical as compression ratio move UP. Building a 8-1 turbo engine is SO much more forgiving regarding perfect CC numbers that a 13-1 NA engine.
