Ford X/Flow/ Pre X/Flow
Protune are masters in the X/Flow and Pre X/Flow
department having endless success even today. This engine just
goes from strength to strength. With all the years we have spent
racing and developing various specifications we can honestly say
that we have not had a single failure to date. As with all our
engines we only use race proven parts that we have tested ourselves.
We have won many races, championships and set lap records with
our X/Flows and it is one of our favourite engines.
Our specs have proven reliability with superb drivability and
deliver good smooth power and torque. In fact our 160+bhp 140
ft lb 1700cc spec cast engine has proven to be a drop in and play
engine. We have built many of these and it is our most popular
by far giving years of enjoyment with just regular servicing (engine
oil, filter and tappet adjustment).
This spec is commonly used for race, hill climb
sprint and it makes a fantastic road engine. We fitted this spec
into a Caterham 7 and to date has done some 5,000 hard track miles
in UK and Europe and is still going strong without any problems.
Caterham 7 owners have enjoyed years of trouble-free
track and road usage from this specification.
We also offer all steel spec engines 180+ bhp
for the more serious user or can build to your spec/budget.
As with the X/Flow we have been building these
for many years with the same success and results. At present we
are still having outright race wins and outright lap records in
the HSCC Historic Road Sports championship with the Lotus 7 S2
in the hands of Andy Shepherd. Andy has enjoyed years of race
winning with Protune Pre X/Flow, X/Flow and Lotus Twin Cam engines
as have many others.
