Air tank size vs CFM tornador black

Ok lets say tornador black uses 5cfm @90psi
Which air compressor will work better?

20gallon and 5.2 cfm@90
10 gallon with 11cfm@90
10gallon with 16.5cfm @90
 
I`d go with either the 11 cfm or 16.5 cfm. The Tornador Black can be used at max 6.4 cfm, so you`d be missing on some of the power with the 5.2 cfm unit.

My inner "Tim the tool man Taylor" says to go with the 16.5 cfm just in case you ever want to run more powerful tools :)
 
That was my thought too, but wasn`t sure how the lack of air reserve would effect tool runtime even though it supplies more cfm then tool consumes
 
Ah good point. Using the Tornador at 6 cfm...10 gallons isn`t too big.

If my math is right that will only give you 15 seconds of run time?

6 CFM = 44.88311734008 Gallons Per Minute or 22 gallons per 30 seconds or 11 gallons per 15 seconds.

I think you need a larger tank...

I remember reading a post on AGO and someone tried it on a 5, 7 and 10 gallon tank and he recommended 10 gallons at the bare minimum. But 20 gallons would be much better. I`ll try and find it to link...
 
Found it: Tornador: compressor test

Conclusion: A large storage tank or a high cfm compressor is the key to getting maximum benefit from the Tornador. A large tank would allow you to blast around with the Tornador, then wipe clean with a rag while recharging the tank. Since large tanks are cheaper than high cfm compressors, go with the biggest tank you can find. I would recomend at least a 5cfm compressor with a 10 gallon tank at the minimum, a 25 gallon tank would be even better.

Yeah, I seen that threads, and imo his test didnt mean much to me as the compressors he tested were all outclassed by the next...all largely dissimilar, non with similar specs.

Now a test consisting of a properly matched compressor(who knows what that is lol)to tool vs low reserve/high cfm compressor vs High reserve/low cfm compressor is what I`d like to see
Like 20g 5cfm(high reserve low cfm)
15G 6.5cfm(cfm matched per tool)
10g 9cfm(low reserve high cfm)

Or even same reserve but different Cfm ratings

Would one with higher cfm last longer or will they last same since both 20? Imagine this answer will vary depending on tool consumption to cfm output of compressor ratio

will high reserve compressor bandaid the the runtime of tool since tool requires more cfm then the compressor outputs
Will the high cfm compressor compensate for the lack or reserve since it puts out more cfm then the tool can. Consume?

My handicap my Kia rio5 hatch.
I simply don`t have height for a verticly and even some horizontals
The horizontals that do all are similar spec 15-20 gallon 5.3cfm at 90psi
The wheelbarrow compressors I found will easily fit, but 10g tank and 9cfm to 16cfm
 
The Tornador Black does force my 10 gal compressor to run most of the time. Mine is the 2hp Harbor Freight model and I just leave it outside with a quality hose. Doesn`t bother me much that way.

The 10gallons I`m looking are 6hp and 9hp and feed more cfm then the tornador uses, so curious if the drain time/kicking would take longer
Other then that is yours adequate enough to you??

You know what..I can always run an auxiliary tank inline if I feel I`m lacking capacity`

Quite happy with the set-up. For my needs and limitations, really don`t need more.
 
I am no expert but have used some tools and paint guns over the years and from the 3 listed I personally would go with the highest 10 gallon compressor. Even though the 20 gallon is say .2 CFM higher than the output of the tool in my limited experience the compressor still will not keep up. It seems that a tool rating never seems to match a compressor rating. I would go with the high CFM smaller tank before I would pick the larger tank and the real low CFM. If you have room for a 20 gallon I would personally look for a higher CFM pump though, at least double the 20 gallon listed. Just remember the higher the capacity the longer it takes to recover when empty. The lower the CFM the longer it adds to that time.

Thanks
If I had the room(height) they sell a 25g with same.motor/cfm specs as the 10 gallon versions
Prices are practicly the same too
So, even if I add an auxiliary tank I know it`ll take it like a champ
