It is mandated by a local (Midwest) vintage racing authority
(VSCDA) that I must run straight water in my cooling system.
I can, however, add water pump lubricant and Water Wetter
(real or "home-made").
That is what prompted my initial question regarding my 7 psi
radiator cap yielding a 225 degree boil over point. I wouldn't
mind using a higher psi cap (if one was available) but am
unsure exactly how much pressure a Mk I radiator can handle.
I imagine the filler neck could be modified for non-LBC caps.
Has anybody obtained/used a higher psi-rated cap and used
it on the early down-flow cooling system?

The EGW (coolant) has a very slight effect on raising
boiling point. I have to run, but will give exact
info later.
And I really hope you can predict when stuff overheats
- that's what I do all day.
