I just purchased a fluidyne radiator because it was supposed to an OEM fit.

Everything went back in fine EXCEPT the PFS intercooler fresh air duct. It seems that since the fluidyne is slightly thicker the electric fan shroud sits a little higher. That puts my duct about an inch higher than the IC.

For those of you with the same combination how did you get it to fit? Do I have to dremel down the fan shroud a bit?

This forum has helped so much and I call upon all once again!

 

I've heard of people both shaving the shroud and cutting the duct in order to make that combination fit.

 

I have your exact setup and have about an 3/4" gap at the top. Unless your car is a show car I wouldn't worry about it.

I will say though to make sure you use the duct even if it doens't fit perfect. I ran mine w/o a duct thinking it wouldn't make a big deal. WRONG, the duct dropped my temps 20-25 C.

Also be careful dremeling the shroud, its not very thick.

 

I'm interested in this because I was planning on buying the Fluidyne to use with my PF intercooler. Are you still using your A/C?

 

If your asking me, yes I am.

 

Yes, I am still using my A/C. I don't know how others go without it unless they live somewhere where it is cooler. I find the car is so aerodynamic that even with the sunroof and windows open in the summer it can still get pretty hot.

From what I see everyone with this combo just lives with the gap. I was thinking of grinding down the brace for the fan motor to see it I can get the fit closer.

 

I am using the Fluidyne with a PFS IC/duct setup. It does seem that the duct is an extremely tight fit, and was a major PITA to get in there, but mine does line up witht he IC fine, I dont believe there is any gap up top.

 

Agreed, I have the PFS SMIC and a Fluidyne...the duct is a tight fit but fits OK. I do not have a large gap. You do have to be careful not to smash the fan wiring.

 

I know it's an old thread but I'm having this problem now. Can I see a picture of how deep the duct actually goes? Currently I have an aftermarket Radiator, I'm not sure which one it is but the duct wont fit.

The only thing I know about the radiator is that it says "Racing" on the top. I've still got the air conditioning radiator in place so I can't see if it has any logos.

I've got the Fluidyne radiator sitting in my garage and I plan on installing it. I just don't want to hack up my PFS duct to fit with this other radiator if it will fit with the Fluidyne.

I think I'll use the stock duct for now with the PFS IC until I get a chance to install the new radiator. Does anyone have any experience with this? Is it even worth putting it back in?

Thanks again guys,
Jeremy

 

It would be impossible to run the stock duct with the PFS IC....

Maybe your radiator needs to be lowered further on the mounting brackets. It is a bit of a PITA to get that duct to slide in correctly.

 

How would I go about mounting it lower on the brackets? They're welded to the radiator. Please elaborate. I'd love to lower the radiator but I looked at it for about a half hour and could see any way to do it other than cutting the welds with a cutting torch and rewelding them and I don't have that kind of equipment.

Thanks,
Jeremy

 

Update: Just found the radiator that I have installed. It's a CSF / RadiatorWorld racing radiator.

Gonna have to remove it to install the duct right?

I've got a Fludyne radiator and I'm going to install that one this week. That should fix the problem right?

Thanks,
Jeremy

 

Bring this back from the dead because this is exactly what I would like to know. Has anyone tried this? Since the PFS duct is such a problem with the koyo, has anyone made it work with the stuck duct? Maybe with some clever hacking and/or fabrication?

Thanks for the help!

I had the same issue when attempting to fit the PFS IC duct with the Fluidyne radiator. Eventually, I had to cut a diamond shaped hole (approximately three inches) on the fold of the duct that was rubbing against the fan and remold the duct to allow for the thicker radiator.

As a temporary fix, one can use a thin piece of metal (I used coping.) and a hammer to create a formed, domed piece with flanges that fits in the diamond shaped hole. The flanges can then be siliconed/taped to the outside surface of the duct. This allows the duct to be lowered and then connected to the IC.

 

I've had the Koyo and the Fluidyne Radiator. I also rock the PFS Medium IC. The Koyo will not work but the Fluidyne is piece of cake. You shouldn't have to hack up anything on the duct or the radiator. What I did was mount the Fluidyne radiator lower on the mounts by bending them down. It's fine because the posts from the radiator still fit in the holes. I used some rubber washers around the posts to keep any rubbing or noise down.

 

Damn John, one post in 6 years on the forum? No one's gonna acuse you of being gabby.

Good info to consider anyway. A soon as my motor goes back in, I'll be dealing with this same combination. If you happened to have any pictures of what you did, that would be great too.

 

My PFS duct already has an indentation molded into the fiberglass that fits perfectly on the fan shroud. R U sure you've got the PFS IC duct?
