Don't know how it can be a moot point really. The best heads flow more at high lift.
All the stats I've found seem to measure at 0.4 or 0.45. Your own TPR2 spec quotes a max lift of 0.41 int & 4 exh
Here's what I've found.. I've calculated the %age flow increase over stock from the numbers published to give some comparison..
Int 3.8% @ 0.4 Exh 4% @ 0.4
Int 22% @ 0.4 Exh 33% @ 0.4
Int 14.3% @ 0.45 Exh 36.5% @ 0.45
Int 25.7% @ 0.45 Exh 34% @ 0.45
Int 11.4%, Exh 18%
Int 9% @ 0.4, Exh 25% @ 0.4
Can't find any stats for a Thumper head though. Can you share?
Think you'll find Thumper doesn't have any / doesn't share, and rmw don't need toCan anyone please update this with Thumper TPR1/2/2R and RMW's head(I believe there are two)??
Tested at different water level'sSide note, closest comparison through reading this thread carefully, Jan said his heads exhaust was 188cfm while it's quoted above that the tpr3 was 121cfm on the bench... Flame on, sorry I don't know what this means for MY needs.
Thanks Phil, not sure what that means but thanks for that.Tested at different water level's
The start of this thread was for a Head comparison, thought this was a good place, but may start a new one as suggested.Youre probably better of starting a new thread to get the info youre looking for….also i dont think it would make sense to have a chart coparing the TPR-1 with RMW's head. The RMW would need to be compared with the TPR-2/TPR-2R
