[Spridgets] Blanking sleeve and blocked bypass again...

[Michael MacLean]

Well, let me know what happens.  You have my curiosity up.  The thermostats
with the blocking sleeve are quite expensive and you are limited in the temp
range.  I did run with a blanking sleeve at one time, but I did not block off
the bypass.  I don't remember having good results with that, but I did not
know much about the cooling system back then.  Besides, it was something I
tried on the original 948 I had in the Bugeye at the time because it was
overheating.  The 1275 I have in there now runs at a perfect temp all the
time.  Gerard built the short block for me and did an exceptional job.  His
work is impeccable.

I was just googling thermostats.  Some modern ones are 
two
stage affairs so that when they open they have another valve 
that closes the
bypass.
 
A solution that might work for you and I.   Drill a 
small bypass
hole (maybe around 3/16") in the thermostat 
itself.
That will allow a small
amount of flow to bleed past to 
let the thermostat know things are warming
up.
 
I don't know,   The more I think about it, it might 
just be best to run
without the thermostat.  
I'm curious anyway,  I'd like to see how cool it
runs 
with the bypass blocked on a hot 105F day.  
 
If I'm driving it on a
cool day I'll just get on it harder to 
make it warm up.
