big mouth vs accel base
which flows better with little or no modification, TPIS Bigmouth or Accel's superram base (no runners, just the base comparison)?
I know this is oft asked but couldn't find an appropriate thread!
thanks guys

Re: big mouth vs accel base (Ramanstud)
I would like to know the answer to this, too as I am building a new motor. I have heard that the TPIS is an Edelbrock with the TPIS name on it. Another question to add to the discussion is what happens when you use large tube runners? Do you need to port the intake openings to match the larger than stock runners?

Re: big mouth vs accel base (vetracer)
I found this data if it helps
TPI, stock base, stock runners, 48MM - 185 cfm
TPI, Accel base, large tubes, lots of porting, 52MM - 212 cfm
TPI, Accel base (cheater), large tubes, lots of porting, 52MM - 226 cfm
SR with unported Edelbrock base, 52MM - 224 cfm
SR with unported Accel base, 52MM - 233 cfm
SR with heavily massaged E base, mild port runners, 58MM - 256 cfm
SR with heavily massaged A base, mild port runners, 58MM - 259 cfm
You might want to run a search, this has come up several times before.
Id say they both flow about the same, ported they can flow equally.
