I didnt read through all this arguing. My car came with no CC. I do want to add one to properly pressurize the tank.
What do you think of a motorcycle CC?

charcoal canister delete on the mk3 bad?

The amount of vapor to collect scales with the tank size. Did your motorcycle come with an 18 gallon tank?

Haha that's what I was thinking. I doubt that little thing would do much for us
So then how are people getting away with getting smaller units? Was the Supra stock one oversized?
They prolly have more pressure in them and perhaps not as much vapor absorbed by the charcoal. It'd still work I'm sure, just not as well. I can't remember for sure, but I believe the factory one is close to 1.75 liters big or so
Once the can is saturated, the vapors spill out of the canister vent. US EPA requirements are quite strict (3-day diurnal + hot soak test and so on) and the smaller canister won't pass (it gets saturated after too many days without a purge).

Not to be picky but in this case the process is adsorption. Activated charcoal is used because of its huge surface area versus size.
I still remember my air pollution engineering class and when activated charcoal came up I thought the surface area in the text was a typo. Unfathomable surface area. Absolutely incredible.
I couldn't believe nobody else was impressed. I was in awe and everyone else was asleep.
I remember adsorption vs absorption, but couldn't tell you the difference off hand.

I know it from working with high vacuum systems back in the day. Sorption and cryogenic pumps, molecular sieves, that kind of stuff.

I checked it out for a bit on wikipedia. My gf didnt find it any more entertaining than you did haha. I think it's pretty interesting stuff myself. Thanks for the vid, I'll check it out later
one thing i love about the supra community compared to lets say honda..... i learn so much about cars here and fundamentals of cars
Thank you!
Thank you!
As others have mentioned the JDM CC is much smaller and designed to work. I purchased one on here a while back by positing a WTB thread. I then ran the feed line to the (US) passenger side fenderwell and mounted the CC in there. I now dont have that huge bastard in my engine bay, have a place to one day place my oil catch can, and still have the full functionality of the CC.
Actually you have partial functionality, since you no longer pass the US evaporative leakage test suite, but at least its better than nothing.
Sorry i do not have the measurements and it is tucked between the fendor and liner so it would take a bit to get at. However, here is a picture of it next to the stock CC that it replaced. I should mention that i was told that it was off of a TTR so not sure if it is smaller then a normal JDM one or not.

I know its hard to judge by a picture... but does this REALLY look that much smaller than that TTR??
for cheap on ebay all day long, it may be worth a shot.

Definitely tough to judge, it looked much smaller than that in the other picture. I'll have to look into this myself, as mine didnt come with one
