With the Huron v3 T6 kit, has anyone found it possible to mount fans as pullers instead of pushers while not having to cut and move the rad forward due to clearance issues?
Not here to debate pullers vs pushers, this thread is about getting pullers to work.
The Mighty Mouse shroud is nice, but the 9" fan is on top, still requiring you to cut the car and push the rad forward in order to run puller fans.
In this image below (not my car) a Griffin without the inlet and outlet on the passenger side was used. What about using a griffin 1-58241-XLS with a custom shroud similar to the one pictured below where the fan is on the BOTTOM, and maybe a smaller 7.5" instead of a 9"? (image below is a 9") The Spal Puller 30100394 is 7.5" and 500cfm and same 2" thickness as the 9" 30100452 that does 650 cfm. Hard to say, even with a 7.5" mounted on the bottom might not give enough clearance. Basically I took the image from MM site and relocated the fan to the bottom, but a 7.5" gives even more room but not sure if it will be enough room. This is just something that has to be mocked up I think because it's hard to tell if it will clear or not.
These images below were taken from evilz99's thread showing a S485 setup with a Huron V3 T6 kit.
Huron V3 T6 kit here as well.
My car has both radiator ports on the passenger side and the radiator is flush mounted with the core support and there is no room between the turbo w/ blanket and the radiator.
In fact, I had to add a small piece of sheet metal to the radiator core to protect the radiator core because the turbo blanket rubbed a hole in the core.
You would definitely have to move the radiator farther into the nose of the car to accommodate puller fans.
As you can see, I'm running dual pusher fans currently.
Thanks for the pics. What pusher fans are those and how are temps? 160 T stat? No room then on the bottom side of the turbo for the smaller 7.5" without cutting?
Also what alternator relocation bracket did you go with? Looks like the rad will need to be moved up this much to clear based on these other pics I found. These ones are spal IX-30100400.
I need to fit a trucool 40K, vintage air condenser, and a 6" intercooler up front so going to have to run mine as pullers.
Both fans are Spal's, I don't have a stat because I run a Davies Craig electric water pump setup.
Temps are mint, car will idle at 170-175 degrees all day, 190-195 degrees going down the highway at 2,500 rpm on an 80-degree day and will cool back down to 180 degrees by the end of the offramp.
Alternator bracket is a Goat Built product, works pretty well, had to shim the tensioner a bit because it kept throwing the belt at 7,500rpm.
Unless you're using a shroud with pullers, then there is no difference in cooling capability.

Thanks again! Those temps look good! I was planning on running the shroud, I just don't think I'll have enough room for the other items if I run the fans as pushers. Going to have to mock it all up. Will look into that bracket as I plan to mount my alt there as well.
Are you running the Davies Craig DC-8065 setup? I think 42.8 gpm is the biggest one they offer?

You mentioned a condenser, I'd definitely try and use a puller setup.
I ran a pusher setup with AC and my temps in general would be higher when using the AC.
Not sure on which DC setup it is but it has the pump/fan controller which all works very well.
Would definitely recommend the Griffin brand dual pass radiator, be careful on the eBay special, seen guys buy them and find out the divider that is supposed to be in the tank opposite the fittings was missing......
Turbo is on the driver side in a huron V3 kit so the area of concern is going to be the distance in red and the distance in orange and if the smaller 7.5" spal puller fan or even a 9" has the needed clearance in that area. I would think that the larger 16" fan on the pass side would be OK. Going to have to mock it all up with cardboard and if it's a no go, then probably just cut the rad support and push it forward. That should still leave enough room for the trans cooler, vinage air condenser and the 6" intercooler. Those items may also still fit using pushers but I would think that the air flow would be blocked. I have a burkhart front bumper support. Undecided on fully cutting it all up and using the RSM front end kit just yet. Going to open up the front bumper as much as possible for air flow. Power steering will be replaced by volvo electronic setup. Alternator relocated like you have done and maybe use an electric compressor with the vintage air mini setup to keep AC unless a sanden air compressor can go where your alt is at and not interfear with the BOV's and the alt mounted top driver side. Can't mount the alt in factory location because I'm going to use a 5" to 4" downpipe through the BMR turbo K-member with a cutoff to retain full exhaust and keep the center mount look. If it robs too much power, I got a full 5" downpipe ready to go and will just cut the bumper. The weight savings would be nice in that case. Rad in back or trucool in back with fans is another option but would prefer to keep it all upfront if temps are reasonable.

Yeah it may come down to having to cut the support and move the rad forward no matter what to run pullers. In that case I'd just use 2 spal fans with shroud and ditch the large/smaller spal fan idea. It's the legit 1-58241-XLS that I purchased.

You may want to consider using a single 16"or 18" brushless fan with a shroud.
The shroud will ensure you pull air from across the entire core so two fans may not be required, one really good fan may be plenty.
Just a thought.

Will look into the single brushless fan. I also have a pair of Mishimoto Slim Electric 12 pullers that I picked up awhile back for cheap but those only pull 1150 CFM each and not sure if they are junk or not.

There is a post on here going over the new Proform Brushless fans a user upgraded to, and he seems very happy with them.
Wanna say it was pulling somewhere in the 3,000-cfm range, plus its PWM controlled so you can ramp it in slowly as temp increases versus it just coming on full blast all the time. Proform brushless cooling fans? - LS1TECH - Camaro and Firebird Forum Discussion

I will check that out. Saw one setup where they had a pusher fan on one side (bumper side, driver), and a puller fan on the other side with shroud (engine bay pass side) with the griffin not having to be pushed forward.
I wound up going with 2017 chevy 12” volt brushless pwm puller fans. I had to cut the bottom stock rad support and have a new one fabricated so that the griffin rad could be lowered and pushed forward, right up to the hood latch support. This gave the needed clearance for the S488 turbo with compact race cover to fit. Pics are in post #5 here: https://ls1tech.com/forums/forced-in...-220-pics.html
In the spring I’ll have a custom shroud made for these fans where the fans are built into the shroud to save another inch or so on clearance.
