Throttle body adapter

[David Gregory]

I've been doing some research and it seems these things are made for the GN?
So it would bolt to a "standard" intake, i.e. edelbrock?  These guys here
(http://members.aol.com/bigturbo1/buick1.html) have one that is meant for a
90mm Ford throttle body.  Perhaps this is the one the orginal poster saw the
ad for.

Digging a bit deeper, i found a GM part number (25525146) on www.gnttype.org
for "intake, upper Plenum".  www.gmpartsdirect.com has that part number
listed for $52.97.  I assume that if there are several alternatives for the
GM part, it doesn't flow particularly well.  But how well does it flow?

I also had a question about TB sizing.  Whats a good rule of thumb to
estimate the flow capacity of a standard round TB?

Thanks,

David

Precision Turbo & Engine in Hebron, Indiana does one of these.
http://www.precisionte.com/main.htm     I think someone else does but can't
think of who it is. I do right much business with PT&E and they are pretty
fair people to deal with. later, Mark
