Fluidyne Unresponsive

Hi all, I have a Fluidyne FHP35-CTSVJX heat exchanger going in and the shop is having trouble with the install. They have attempted to contact Fluidyne regarding the issue with no luck. Has anyone here been able to get help from them with tech support? The shop is trying to get some answers on fitment as they are having trouble getting the heat exchanger installed.

Also, if anyone has any info on the install of their latest 5-Row 3-pass heat exchanger that would be great.

Thanks!

I installed mine with very minimal “fabrication” work. Maybe find a new shop?

I centered mine below the crash bar and used an 18" length of fine wire (Amazon link) to fish M6 bolts through the holes I drilled from either end, rather than a cutout. Flat washer, lock washer, blue locktite, and the nut. Looks the same as 713V's above.

Maybe find a new shop?
I concur.

Yes, that one. I do remember that the steel is harder than hell and went through several new bits, but got it done…

If you have a 2010 or later model, use Cobalt drill bits on the crash bar.

I doubt you are going to get any support from a company like Fluidyne because their product spans many applications. As stated earlier, I installed mine with no instructions because I obtained mine used. The shop should be able to figure it out by looking at the mounting tabs and hose locations.
If I recall, the stock hose in terms of location should fit no issue, however I do seem to recall that the outlet (or inlet?) was larger than the stock hose. This fact drove me to eliminate the factory hard line and run 3/4” or 1” heater hose.
You might consider replacing the stock intercooler pump with a more robust pump, like a Pierburg CWA (?) due to the volume increase of the larger intercooler. Now would be a good time to consider either an under hood tank or remote tank.
Regarding performance, along with the above mentioned mods, and a larger reinforced brick I have IAT’s under control. It is certainly doing what it is supposed to do.

I agree find a new shop.

Install was not intensive at all, hardest part was the drilling. The rest was cake work.

I had to shift mine forward for clearance as mine has the fans on the backside

THIS^^
Is my case as well. It is an exceedingly simple task for any experienced hotrodder, I mean really. I would definitely find another shop if these guys need instructions for this.
In my specific case I drilled and installed rivnuts into the underside of the crash bar.
The notes that I would offer up is this: on the chance that you might someday decide to add the SPAL fans that they offer, go ahead and mount the HX as far FORWARD on the crash bar as you can, keeping the tabs within the bar. There is only a small amount of latitude front-rear but that half-inch makes the difference in being able to mount their fans as intended while NOT hitting the AC condenser or them not fitting in place.
Also, I DID speak to someone at Fluidyne when seeking to buy their fans. She was nice enough to tell me that
1. they were out of stock
2. I should buy them from Amazon as they would be much cheaper
3. Use this Amazon link
4. I find that this HX NEEDS fans for around town. it's fine at speed without them, but with its low mounting, it does NOT get effective airflow from the factory radiator fans. It NEEDS augmentation.

I don't have install help but I do have a question.

This looks like a really nice HX. Is this a newer offering? I have the weapon X track attack that I have yet to install. Is this Fluidyne or a C&R recognized as a better option than the track attack? Curious, about what factors made people pick this design over the bigger frontal area but thinner track attack style design? This one is likely more aesthetically pleasing but I'm after the unit that sheds heat the best. Any feedback or thoughts?
Once it heats up more here, I can tell you more. I've got the fans hooked up to come on when accessory fan comes on(I need to change that this year, I have a thread on it I haven't updated in a while) life got in the way and I dug a 1+ acre pond lol...... but I digress, so far with the Temps here it recovers pretty quick for me so far. Fans should make it quicker once I fix them. Maybe someone with a track attack can chime in... I can give you so recover #s and times but it will be a little while before I can
As far as installation, drilling and tapping a hole is also an option
Thanks! I'm curious about what others think about it. The installation on either doesn't seem too crazy. The design of either is pretty different. I'm a function-over-form guy. I just want the one that cools the best.
