JDL fan shroud vs Mishimoto fan shroud
 

Hello,

Just picked up a turbo kit and I'm researching fan shrouds for the OEM radiator. I saw some people say the Mishimoto fan shroud was no good but these posts were lacking in detail as to why/how so I'm wondering if the JDL is worth the extra scratch?

Use case:
2017 86, I don't wan't more than 300whp on e85. Occasional autox not really any track. Already have oil cooler.

thanks! Tried searching using google and couldn't find any definitive answers.

I have the Mishimoto slim fan shroud. Have not used it, but it's installed.
It fit well, obviously easy to install, plug and play fans are nice. The welds are absolutely ugly, but they aren't holding liquid so they'll do.

If the price is similar, support JDL and get a fantastic product instead. I have no data on these fans yet

In darkpira7e I trust. It's about $200 less for the mishimoto.

Ah I did not see that the fans were additional cost on the JDL shroud. I am certain it is still worth the cost over the Mishimoto shroud and fans.

I have the Mishimoto shroud and its fine for the job it does,( the Mishimoto fans are not that great though).
I've added Spal fans, and simply cut bigger apertures into the Mishimoto to allow the larger diameter Spals to fit.
Still holding together fine, no signs of fatigue or failure.

Were you overheating with the mishimoto fans?

Yeah, under hard use at lowish speeds, but to be fair the car is supercharged.
If you compare a high volume Spal next to the Mishimoto fan, the difference is quite amazing (and ideally run a direct power source from the battery or similar)

i run the Mishimoto Radiator/shroud on my JDL turbo. Coolant temps are about 195-210 while driving/stopping. Also run their oil cooler (mishimoto) and oil temps stay about 185-205 driving/stopping. in arizona heat

Turbo or supercharged?

Turbo

Do you autocross/track?

No I don’t. Street driving daily

I went with mishimoto only because plug and play convenience. If you are good with wiring go with JDL. Also I live in CT so I'm not too worried about my temps when the turbo is install because it gets cold up here majority of the time and this car is my daily year round.

I just installed the JDL Slim Fan Shroud, build quality is amazing. Only issue I'm having is figure out the wiring part. Was told a 14 amp relay is what I need (if anyone done this already let me know)

I’m running the Mishimoto, so far, so good. Ill be heading to the track in a couple weeks, we’ll see how it holds up

Sweet, I just finished getting all of my parts, deciding if I want to install the turbo setup sooner or later :bonk:

Pick that big of a relay or larger. Use the existing fan wiring that powers it to activate your relay. I don't think it's run via a relay already. The stock fans are weak. Use the relay to wire in directly from the battery with properly sized (larger) wire to handle the added current the better fan system will draw.

You can look up data on wiring gauge and how much current each size can safely handle. Then check your fan amperage and add a 1.2-1.5 safety factor selecting your wire.

HKS SC on a 14 FRS for reference. I never see my stock temp needle move off the norm it's always run. I watch it closely, but just don't really push that hard or do any track or autox. I'm used to the car much feeling much warmer before the FI upgrade.

Yeah I'm trying to look for the wiring gauge to buy & a diagram for guidance. Have the relay waiting now. If you have useful links please let me know

Just look up a relay schematic, then select proper wire. I gather the fan kit will tell you amperage draw requirements. Add some wiggle room to your fuse unless actually specified in the instructions.

Your power wire for your OEM fans is now your signal wire to flip the relay. And you retain stock on/off temps. Not sure how to change these, probably in the ECU. Or you could wire a switch to run them yourself, on command. Not sure I'd do that either, if I did, I'd wire both in so I could turns fans on or off, but keep the OEM signal wire in the loop as well. This would be some double relay setup and creative wiring.

I wired my Vanagon back in the day to split the batteries to individual service so I could use the starting battery to run the stereo/car when running, and the RV battery to run the stereo and RV side (lights/waterpump) on a different battery so if I killed it with the stereo or lights left on, I still had a dedicated starting/auto battery. It worked awesome.

Quick look to try and help. Looks like a good source for guidance. Draw your own schematic first using a relay schematic, then it's just putting placing the bits and putting it together. Some good crimpers or solder and heat shrink.
