Spal Fan Shroud & Koyo Radiator
 

We're still waiting on the turbo for our kit build but in the meantime we've been working on supporting mods.

For our race car we wanted to go ahead and put a Koyo radiator in along with a proper fan shroud with Spal fans. We also want to make sure our turbo kit will comfortably fit the largest radiator and fan setup anyone would need to run.

This fan setup will also fit the stock radiator for those interested.

Finished... Not much room to spare.

Temporarily installed for pictures, we are waiting on some seals for the back of the shroud that should arrive tomorrow. We also have some wiring left to do, we are hoping to make it plug and play if we can find the proper connectors. For our car we will be using DTM connectors.

Very jealous of all the tools in that shot with the blanco table

MAN I wish I could run a shroud like that, but there's just not enough clearance on my car with the turbo kit and thicker radiator.

Aren't you running the Full Blown Kit?

He's coming out with the Fan Shroud.

Thanks, it looks like I may be trying that FB shroud out with some thinner fans.

I think that might work with the Full Blown kit. I would buy it in a heartbeat if I still had my car. With the shroud and higher flowing SPAL fans, I bet it would fix any idling/traffic temp increases.

I don't know if you could make it any thinner. This is only 2.65" deep at its very deepest point (measured from the back face of the radiator core). We used the thinnest fans Spal makes and only have a shroud depth of .65"

Any thinner than that and you either have a nonfunctional shroud (honestly this one could be deeper) or you have a crazy thin fan that isn't going to flow much.

I meant the thinner Spal fans.

My tuner checked the specs, and the Spal fans are slightly thinner than the FB fans, but flow a little less CFM's. They may be more efficient with the shroud though.

Those fans are nice, I just got some SPAL's and I must have ordered the wrong ones, mine are thicker then yours.

These are the thinnest Spal makes as far as I know. If you find different let me know. The part number I'm using is 30100375

noob question, but are these fans more efficient than the OEM thicker fans? Or efficiency on the fans do not matter?

they blow less CFMs

Lower CFM but lower amperage draw as well. They are definitely a less efficient blade design because of the shallow fitment. Spal makes hands down the best aftermarket fans out there and they are very efficient for their size. These will provide adequate cooling for any conditions with a Koyo radiator. I probably wouldn't recommend going on track with a stock radiator and these fans but then again I wouldn't go on the track with the stock radiator in the first place.

Once people take a look at the stock radiator and realize it's the same size as the ac condenser more will hop on the aftermarket radiator.

The prototype is finished and actually already sold... I really didn't even want to take it off my car but I can't complain about selling them faster than I thought. Hopefully CSG Mike will have a review as well as fitment feedback on a RobiSpec radiator.

Wiring is done with Raychem, Tefzel, and Deutsch DT Series connectors.

The seals came in today as well, they are a perfect fit against the radiator all the way around.

We added this clip to help keep the rubber compressed all the way across. You can see how much more room is gained for a turbo setup.

I had to at least take a picture of it fully installed before I pulled it back out to ship.

So with the Koyo rad and this fan, will it be a cooling upgrade overall compared to the OEM setup? My custom turbo kits hot pipe does run very close to the OEM fans, just like the FB kits do.

If this doesn't compromise the cooling, I am very interested so my fans don't melt..

How much are you selling the combo for?

(Fans and shroud)?

Will you be offering this with a thicker SPAL fan? I'm not going to be going the turbo route so I have some extra room and would like the extra air movement. I like what you guys are doing. Keep up the innovative work.

Yes, this will definitely be an overall cooling upgrade. I would also recommend a low temp thermostat to complete the setup if it is a track car. If it's just a daily/weekend warrior the stock thermostat is better.

We are selling the whole combo for $400.

We definitely could, there are a number of SPAL fans with identical mounting points. Most of the larger fans are almost double the price but we could definitely put a package together for you if you're interested. Feel free to email me at ben@carolinadyno.com or PM me if you're interested. For the turbo guys you could also run a thin fan on the turbo side and a large fan on the open side. Honestly though there wouldn't really be any reason to increase the fan size, there should be no cooling issue regardless of climate or use with this setup so all you would be doing is adding draw on the alternator.

Oops :D

When will these be available?

@Carolina Dyno: Ben, do you know the CFM of the stock fans?

Wow great deal!! I will for sure jump on buying one of these!

I wish I did. I assume it's a good bit higher than any slim fan just by looking at the OEM profile but that's just an assumption. I don't know of anyway to find out besides having one tested by a third party which probably isn't worth it, there's not much we can do with that info although I'd love to know as well.

Thanks, we should have them available within the next week. Our online store will be up shortly as well.

I'm happy to report that the shroud fit on the Robispec radiator. We did have to supply our own hardware, but that's our fault for being in a rush to purchase the prototype... :)

can you please post when they are readily available for sale? i am interested!

This gives me plenty of room for LSX swap and room for little spooling action!

Sorry about that, I could have thrown some in if I knew you needed it. Glad to hear it fits well, was the seal properly pressed up against the core? There isn't much wiggle room with the seal we had to use.

Absolutely, they should be ready around Wednesday next week. Our online store will go live at the same time. Ill post the minute it happens. Thanks for your interest

Have you already started the swap? There should be tons of room I'm interested to see the finished swap.

@Carolina_Dyno No I haven't but just by looking it would give me room for FI on the LSX engine where it would have been tight before. I am still aquring parts at this moment

You are in my State and not that far so this is for sure on my got to buy list now

If i could get someone to buy my FA20 engine and transmission and help put in engine & trans, i would have enough to do the swap in the next month or so. I already have the engine just needing a few things to complete the swap plus mods for LS engine

This all looks to be fantastic:bow:

Oh, it's our fault that we were in such a rush :)

was the seal pressed properly against the core?

So how much will this be without fans?

@Evasive Motorsports did the install; this actually is currently on @ImperiousRex's turbocharged car. I did, however, see pictures, and it is sealed all around to the radiator.

We used a SPAL 12" slim and 12" medium fan. The fatty fan (that I would prefer to use myself) did not fit due to the Greddy turbo kit. I believe it will fit without issue on a non-turbocharged car; fitment is TBD on other FI solutions.

This is a quality piece, and I don't often say that :thumbsup:
@Carolina Dyno: Ben, I suspect we'll be ordering a few more of these in the future...

We will be selling these with no fans or hardware (just the finished shroud and rubber seal) for $175 plus shipping or $400 plus shipping complete.

Great to hear it fits the robispec, we'll add it to the fitment list. Thanks for the good words.

For anyone in a rush, we got a couple of these done tonight. They will be finished and have the fans mounted as they are ordered to allow for custom options. The website should be live on Wednesday but we can accept PayPal or CC by phone until then.

Nice work! I'm expecting to get my car back from @Evasive Motorsports in a couple days and when I stopped by last week to check out the fitment, everything looked good. Dennis at Evasive did mention they needed to trim a little around the side hosing for the radiator as well as provide the nuts and bolts to get everything fastened on but it wasn't anything major. Can't wait to test out the new fans and shroud at the track next weekend and thanks so much for accomodating me via @CSG Mike :)

Good to know, I would love to know where they had to trim it so I can update the design to fit the Robispec without issue. I only have a Koyo, and stock radiator on hand.

I'm glad you're happy with the shroud, let us know how it goes on track.

Should be soon Ted :burnrubber:

Our online store is now live at store.carolinadyno.com

One more pic while we're at it. We are pretty lucky with this platfrom to be able to perfectly fit these fans, notice how little space is left between the seals, it's almost all fan. We did everything we could to make sure there is no overlap around the edge of the fans, even between the two. The only place the aluminum protrudes into the fan surface is at the bolt holes and that's completely unavoidable.
