Horace - the rebuild
Horace has been sitting idle at WPVW for nearly 2 years whilst we have concentrated on drag racing , hill-climbs and super-sprints ......
The engine in Horace has been stripped down for a full rebuild in the attempt to gain more power from the 1641 NA engine . Last dyno session it
produced 93hp @ the wheels , and I am now looking for 100+hp .
The Scat crankshaft is linished and a new set of alloy Pauter Pro-series conrods are to be used .

Horace - the rebuild
2 years ago Ben Ford was at the wheel of Horace when an inlet valve broke while the engine was turning 7000rpm ...... the damage was fairly
substantial with a valve going through the piston , massive damage to the combustion chamber & valve seats , and the valve stem came back up the
inlet port ( punching a hole through the inlet manifold )
the cause of the broken valve was due to an inlet valve guide coming loose in the head and as it shuffled up & down it wore the hole in the head
(where it is located) so badly that the valve was coming down crooked into the seat , which in turn stressed the valve and snapped the head off
.......

Horace - the rebuild
the bottom end is assembled and a piston is fitted to 1 conrod to check the deckheight .....
the new Pauter conrods look half the size of the piston that is attached to them , I dont think the conrods will be the weak link in this little
engine
the cylinder head is welded , machined & new valve seats installed along with new valve guide
porting then starts around the chamber & in the ports

Horace - the rebuild
the ports are all cleaned up , the chamber is refaced and the head is ready for final seat cutting
note the spacers used in the chambers.... these heads with 42mm inlet & 38mm exhaust valves were previously used on a speedway midget which was
bored for 94mm barrels . I had to have spigot sleeves made to locate the 87mm barrels into the heads for the 1641ml engine

yep Craig ..... when we made 93hp@ the wheels the compression was 11.4 , now I have set it to 12.5 that should make great
power with the right tune .....

Horace - the rebuild
the spark plug hole is re-drilled and the seats are refaced in the heads . I then lap each valve into its seat and check the valve face & seat
face with bearing blue to ensure a perfect sealing surface

Horace - the rebuild
after calculating the compression ratio at 12.9:1 , I have decided to install a set of .020" barrel shims to bring the c/r down to 12.5 .
the pistons and barrels are installed with Berg circlips and hi-temp silicon sealant at the base of the barrels
