Charcoal canister question Options

[mb911]

I want to add a small activated charcoal canister on my gas tank vent. Is it just activated charcoal in the canister? Thinking something very small any thoughts?

The 914 system is the EASY BUTTON!
Nothing to it.

I once taught "Engine Performance 101" at my local Community College.

Trying to teach something IS the very best way to learn it yourself...

It was the MOST eye opening thing I ever did in college because I got to see what the college wanted from their instructors.

It's a money game, pure and simple!

What I learned (automotive) was the progression of emission control devices, their effect on engine performance, and the resulting changes over the last 50 years...

The when, the why, the changes that came after BIG TIME!

For use on the streets the ONLY reason to NOT use both a PCV and EVAP system is if you have a complete perfect concours example of something that didn't come with it in the first place.

I once told a Bloomington Gold 63 Vette owner that wanted EVAP to build an external garage as adding it to that car was sacrilege in my book. His wife bitched about its odor in their garage...

ALL of my street cars will have active EVAP and PCV. I will use a series of catch cans and filters to not allow the heavy hydrocarbons to hit the intake but the light ones will get burned!

If you also apply modern build techniques and accurate DFI you can make a serious preformance car that is also multiple times cleaner than the original today.

From no emissions and crappy build specs to modern full-on stuff is about 1000/1

Yep, 1000 brand new 911s are cleaner than one early one.
Bunch faster as well...
