While the event seemed like an explosion, the fan cut through my fingers about every inch until the blades were gone. The fan went into my hand from the radiator side and pulled it in, and neither the fan nor I faired that well. I was very fortunate that one of the best hand surgeons possibly in the world was on duty that evening and he took on the challenge with his surgical team. It was his first night back at the hospital after a three week speaking tour. The emergency room doctor had already told me that they would just clean up the hand and amputate the fingers back to good flesh and bone. Just after he told me that, a couple of young doctors came in and said they were looking for a challenge for their surgical team, and I was definitely it.

The fan blade still hangs over my workbench as a reminder to try and not be a dumbass. It's been a little over 10 years and the arthritis is settling in like they warned me, but I have full use of the fingers. Dropped a lot of nuts and bolts for the first two years but surprisingly have almost full feeling in the fingers now. The X-ray was taken just after we walked into emergency and we had gathered up parts and wrapped them up with the hand in a not-so-sanitary towel, and they just took the X-ray through the wrapped up towel.

My wife is an OR nurse and I showed her your xray. She said " what did he get it stuck in". That's a serious injury.

I'm in the process of an engine swap and adapted a MK8 fan to a 68 shroud

That looks fantastic. Did you use an original Lincoln fan or is that a repro?

I have a dual fan setup I bought for $1 off of a dude at a swap meet who didn’t want to take things home on Sunday. Codes out to a G6 if I remember correctly. I’ve been meaning to swap the fans into something usable for an old car. It’s too wide as is.

freebie original with a bad motor. bought a motor on Rock auto. Painted the fan parts with Eastwood plastic renew paint and satin clear coated the original Pontiac shroud. The Lincoln fan I think is ABS plastic while GM used fiber reinforced polypropylene. I couldn't find an economical glue or epoxy that sticks to PP. I used screws and butyl rubber to stick to both plastics. I use aluminum sheet to bridge the gaps and painted inside surfaces and the butyl to keep it from attracting dirt during use.

Also, I will be controlling it with a PWM controller (HF-125) from this guy:

Yesterday I watched an episode of Matts Off Road Recovery (southern Utah) where he was going over his fleet of vehicles and touching on their shortcomings. When it came to his XJ jeep with a inline 6 in it he talked about the fan and the hood louvers. He said that he had tried every electric fan that was highly touted as the answer to a changeover from mechanical to electric, Including the Ford/Lincoln fans that everyone talks up.

He said all the electric fans failed in that application and he kept going back to the mechanical fan for his XJ with A/C. He said no matter the ambient temp he never has to stop and let the vehicle cool down with a mechanical fan like he did when testing the electric fans. I thought it was a good apples to apples test under extreme conditions that in his application he had never been able to use an electric fan without the vehicle overheating. When he switched back to mechanical fans the problem was non existent.

He issued a $10,000 challenge that if anyone had an electric setup that could cool in southern Utah and they could prove it didn't overheat, he'd give them $10,000. Putting his money where his mouth is........

Just for an observation, I've never seen any closed course race cars with electric fans used to cool them, always mechanical fans. i did see one autocross car many years ago with an electric fan that failed miserably after only a lap around the course.

Probably a little known trick to cool oval track cars down during a red/yellow flag was a water reservoir using a washer pump to squirt water over the core of the radiator while bringing the RPM up, works very well under extreme conditions. The water and air mixture together, will pull a lot more heat from the core than just air will.

I think this guy is having the opposite problem that nearly all of us have with the under-radiated 60s cars. Unless I am reading it wrong its not really an apt comparison.

I also never have to stop to cool down....I have to start moving to cool down. Its the stopping that's the problem. And that's where an electric fan would benefit me. I don't think anyone would make the argument that a big mechanical fan wont move more air under RPM, including racing like you said. The problem is getting stuck in traffic, or a drive-through etc. I need more air at idle.

My car is pretty well sorted out, Cold Case, big 19" clutch fan with a modded clutch to engage faster (I could probably bend it a little more even). And its fine, but it creeps enough at idle that the thought of getting stuck in a bad traffic jam scares me. And its hard to keep temp down in the staging lanes unless.

Plus I have the Terminator installed and Im not making use of its fan controls, which activates my personal flavor of autism and annoys me. Ive just always had something more important to spend money and time on than moving this one to electric.

Sounds like you could benefit from adding a slim helper puller electric fan inside the mechanical fan shroud ( if there's enough depth)
