Some say bigger is better
and
others say smaller is the way to go.
I got a good friend who is in the business of air flow, in pipes, ducts
and the like. He also works a lot with automotive ac stuff.
anyway .............
We were talking cars the other night and the subject of tb size came up.
He reminded me about how when we were kids, we saw many times, peeps
believed bigger carbs were better cause they made more power.
I told him you might not wanna compare carbs to tb's
as
tb's don't deal with a liquid like carbs.
He asked me how that made a difference when you just look at the
air flow side of both applications. Both have a butterfly to pass air!
He then asked me to tell him why, in the past, we used different size
carbs for different cars even though all were sbf powered and
to be specific with my explanation.
I said it was simple and it was backed up by what did and did not work.
600 to 650 Holleys for Street Cars
750 to 780 Holleys for 1/4 mile only Cars
We found the larger carb was great on Street Combos for WOT
but
It was lazy down low and at mid range
on the other hand ............
The smaller carb was great on Street Combos for low and mid range
but
It would not produce as much power at higher WOT rpm
He looked at me and said
You're saying ... different size for different application
His next question to me was .......
Why should a Throttle Body be any different
and
I really could not come up with an answer other than .......
Seems like it should be the same principle at work as the carb
btw ... It was Tom Moss talking about this the other day that
got me thinking along these lines and the talk with my friend
was just more info to motivate me to say something.
Just thought I'd share the info for who ever cares
and
I can see how both beliefs have merit here
I very rarely start threads
and when I do .......
I usually look for some good discussion
so
As Always ....... Feel free to agree or disagree
