i have a 62 TR4, which was pretty modified by its two previous owners. i've kept up the tradition; it needed an engine rebuild so we upped it to 89 mm pistons. needles to say, it runs a bit hot. did not have a mechanical fan on it when i got it; it had a pretty strange big heavy metal motor driving a very funny looking little fan. i went to ebay, found a nice electric fan, pinned it to the front of the radiator, and figured i was good to go. been out and driving it for the last month or so, and finally got caught in stop and go traffic. the needle just kept going right, even with the fan on (and i've also upgraded to a 60 am alternator). i don't yet have the shroud on, and i figured i need to move to puller instead of pusher. but i'm thinking i need a much higher rpm fan and i'm looking for recommendations. as i said, i replaced the 30 amp alternator (like i said, its been modified quite a bit) with a 60 amp, so i can handle the pull. or maybe someone can give me some guidelines on rpm?
thanks!
thanks!
