SignUp Now!Sounds like it might be time to upgrade to a Mark VIII fan system. 5000 cfm max. will suck your dog through the front damn ear.
Well, I've been building these fan systems for 1969-76 Vettes, 1st. Gen. F-Bodies and all 1964-88 GM A and G bodies. After mentioning this, I think I should maybe jump on board as a sponsor for the site so as not to sound like a shameless plug...LOL. Anyway, we combine the 1997-98 Lincoln Mark VIII fans (NEW) with the latest Spal PWM fan controller to allow full control over the fan, electric water pump or both. And, we build supplemental relay harnesses for use with them to run either dual fans, multiple pumps and/or manual over-rides for each. We aimed to provide the best fan on the market which in this case is an OEM Ford Motorcraft Mark VIII and it pulls 4800-5000 cfm @ 32 amps max. They measure 22x19x5.75 and can be trimmed to gain a little extra clearance. This fan does not require a HO alternator unless you want to use a relay to trigger it on/off instead of the controller...in that case, we have 70-amp relay kits for that. The idea is to use the most powerful fan available so that it only has to work at 40-50% capacity to keep virtually any engine cool, regardless of how hard you push it. For a boosted car with AC, I can't see a better alternative. The fan will speed up via the Spal controller to maintain a stable coolant temperature. It is triggered of a temperature switch which btw the water pump arm is the best place for it but that requires drilling/tapping. That's where we prefer to place it but the intake will work too. The ony issue is depth. You need at least 5.25" of clearance between the water pump and the radiator-that and brackets for mounting. Any questions about it I can answer at gmachinz@juno.com If enough are interested, I can arrange a GP after I add myself to the sponsor page. We stock about 20 in the shop at any given time and we let them go for $189.99. Dealers sell them over the counter at over $350 right now-crazy. We do a LOT of installs so we are given special pricing on them. If you want details or specs you can also reach me at 515-979-8602. -Jabin.
