Tools R Us is a BAD DUDE!

Dan suggested I give this thread a read to understand the shroud trimming when putting one of the V6 fans in on my to be supercharged truck.

I thought it was a good idea to bump up this old thread for those who are in the process of supercharging their trucks. VERY interesting reading.

I ordered one of the V6 fans and some other fun stuff. Looking forward to the install next month.

Thanks for the bump !!!

I lost track of the depth discussion positioning the new fan inside the shroud. I have not actually layed-out the recommended fan with a trimmed shroud. It seemed that the thread established that the new fan is smaller but seems to move more air.

Would it be practical to put a bead of silicon caulk around the inside of the fan shroud to "tighten" the diameter to better fit the new diameter of the fan? If the fan shroud diameter were 1/4" - 1/2" smaller would it help the airflow much?

Can somebody that has received the new kits confirm that it comes with the same ringed fan ?

Yes. It looks that way.

Hmm - Maybe turbo is the way to go. Slee can you still get the SA turbro kits for the 80?

I'm running the ringed S/C fan with a blue hub and 1000 cst silicone. I have not had any problems with over heating and my temps rarely get above 185 even with the a/c on in slow moving offroad trail situations in 85* weather. I'm haven't had the chance to get into any hotter weather, so we'll see how it does then.

Sure, you can get just about anything if you have the $$$$

Here in az 85 is a nice Cool day and yes...I don't know anyone that has cooling issues at those temps. However, once it's over 100 and absolutely once it is over 110 it is a whole different ball of wax (wait the ball would be a puddle by then)

I could imagine that kind of heat would cause problems. For my climate, I haven't had any problems. If I ever get out of this ice-storm prone midwest I might have to switch fans.

Has anyone looked into an electric fan setup?

 

[-Spike-]

There's a couple of threads addressing electric fans laying around here somewhere. Usually as helpers, but the idea of replacing the mechanical fan with an electric has been hashed out pretty well too. The usual argument for an electric fan is control (i.e; water crossings and such) and the argument against is that the mechanical fan does its job very well, doesn't strain the electrical system, and is more reliable. If you're interested a search will probably turn up gobs of information.

Searching only turned up the JDM fan mod. From what I read here, it seems like the SC replacement fan just isn't doing the job. So it seems to me if you can't get a mechanical fan to pull enough air then maybe you could solve all the problems by using an electrical one that would actually pull enough air.

I'm talking about one large or two medium sized fan in a pull configuration in a custom shroud.

However, I would prefer to just find a mechanical fan blade that worked. Even if it isn't OEM.

All this is preemptive, my SC is on order, but I won't get to install it until I get back form overseas!

Does anyone think this would fit?

The #17118 fan is 18" in diameter and 2" deep. The flange diameter it fits
around is 2-3/8" and 2-19/32". The bolt spacing across the holes is 3" and
3-1/2".

We do not have that fan in stock so I was not able to pull any more specific
dimensions off of it but I did find a #17117 17" fan which should be pretty
close to the 18". The distance from the mounting surface to the forward
most part of the blade is a little over 1" and the distance from the
mounting surface to the rearmost part of the blade is a little under 1".
