<div dir="ltr" align="left" class=""><font color="#0000ff" size="2" face="Arial" class="">Thanks to the Fot members for their reactions : most
are warnings that triple 45 Webers may be too big on a TR6 engine. But it
is a race engine (2720cc) and the owner has already bought 3 good
secondhand 45 Webers with identical progression holes : 36mm main
venturi's seem to be a reasonable starting point in this case?

Webers.</font></div>
<div dir="ltr" align="left" class=""><font color="#0000ff" size="2" face="Arial" class=""> I've seen TR6 racecars with 45 Webers and I
wonder if the Cannon manifold, with 40mm diameter bores on the carburetor
side, can be reamed to 45mm? </font></div>
<div dir="ltr" align="left" class=""><font color="#0000ff" size="2" face="Arial" class="">Another question : the valve seat pressure on my
TR4A racecar is 35 kgs/77 lbs. I've also a cylinderhead with only 25 kgs/55lbs
seat pressure. The springs on both cylinderheads are 5.25kg/mm
(290lbs/").</font></div>
<div dir="ltr" align="left" class=""><font color="#0000ff" size="2" face="Arial" class="">Do you think 25kgs seat pressure is
enough?</font></div>

TR6 Cannon Intake Manifold<br class=""></font><br class=""></div>
<div class=""></div>
<div class=""><font size="2" face="Arial" class="">I have to install
triple Webers DCOE 45 on a TR6 engine. The owner has also provided a
Cannon one piece intake manifold with balance pipes. The bore of the
runners is 40mm on the carburettor side and 31.5mm on the cylinderhead
side.</font></div>
<div class=""><font size="2" face="Arial" class="">Can these runners be
reamed to 45mm/34mm? If not, are there other inlet manifolds
available?</font></div>
