You could clea rance the back of the fan with a 2" sanding drum on a die grinder if you have enough material in the fan. That's what I did with the volvo fan. I'm pretty sure there is a flow equation for space between the fan and radiator but that is probably way more in depth than we need to go.

That's good info and I'll have to measure with the standoff is on the mounts provided but I think Soviet even had clearance issues mounting it flush. Maybe this is what merits using a smaller diameter fan but I can't justify purchasing third fan when I have to kicking around collecting dust since nobody buys used parts around here (where I live).
perhaps I need to get over my laziness for shipping and post them up here on this site |

My testing showed 3/4" is the sweet spot, less is bad, more only helps a bit.

Measured from the rad face to foremost blade surface? fwiw- Spal makes fan gaskets that work as an insulator and spacer. I'm using one on my 16" Spal mounted to the rad face.

doh- that sucks. You could diy with some locking edge trim?

Thats pretty much the same stuff I used too.
These guys have a lot of options too for just about everything. https://www.mcmaster.com/#bulb-seals/=1bsqz22 |

So shout out matrussell122 for sending me a a couple step files including his Mishimoto radiator file so I could reference the A/C fan mount bosses and compare. I don't have a carpenters square so I'm just guessing off tape measure. Matt's help is appreciated.
I rough modeled the dimensions of the Trackspeed radiator with it's 3" thickness and effective areas of interest and plopped the fan bracket on. In it's current position recessed 0.25" from the surface of the mounting boss, it will place the fan at 0.55" from the fins. I think this is as good as I can get and will have to test fit to see if further shimming is required for clearance to the sway bar. https://cimg0.ibsrv.net/gimg/www.mia...d6df356b3c.jpg https://cimg1.ibsrv.net/gimg/www.mia...15b0391962.jpg |
Made a mock up with Lexan. Fan mount hole positions are spot on and it fits the radiator perfectly. I'll have to fashion the mounts to the threaded bosses on the radiator, probably some angle or sheet metal drilled out. Will attempt to make the part and shim with a 0.25" spacer toward the fins and check clearance to sway.

The spal 14" has flat spots on the fan housing (like most slim fans) which nest perfectly between the top and bottom plates of the trackspeed radiator https://cimg8.ibsrv.net/gimg/www.mia...f1b09a09e7.jpg

Looking good :bigtu:

I keep coming back to this thread to look at that radiator. If you can move your fan to the far left side i bet you could mount your oil cooler on the right side and still have some spare room. Ill send you the oil cooler model and bracket i came up with a while ago.

Thanks, I'll take a look at the files, however without passenger side fan mounts, and how mich closer it is to the sway bar, I'm uncertain if I can get a 25row to fit.
I finally committed to taking A/C out so I was hoping I could squeeze the cooler where the condenser once sat. I believe it might conflict with the intercooler though. Preliminary ideas: https://cimg9.ibsrv.net/gimg/www.mia...da518de410.jpgNotched the rear to allow the core to breath but kept some of the vertical lip for beam stiffness. https://cimg1.ibsrv.net/gimg/www.mia...5f5f4b119f.jpgFlipped the top bracket to the front, will likely utilize existing threaded holes. I think for the stock hood latch I do not have. Please don't mind the mess, I've done something stupid and am in the process of POR15ing the bay. |
psyber, ive got something im working on...right up your alley i think. totally unrelated to the last few posts..
