Subject: Re: [Tigers] Blower/Heater
Hello,
Though my Tiger 1A is tucked away for the Massachusetts winter, thoughts =
of improvements/fix-ups still pass through my head. This question is =
about the anemic demister/heater system.
Two components make up this system
1) the blower with the squirrel cage fan
2) the heater radiator
The blower fan seems like it could use a redesign. SOOOO slow. Mine is =
working same as it ever was. Anybody tried upgrading this?
The radiator seems awfully small. Any smart-guy thoughts on this?
Anything else I should be thinking of? Any Ideas?
Even if the heater isn't regularly used, I'd like to be able to count on =
the system to defog the windshield.=20
