dannobre - sent you a PM regarding the vents, can you share any of the details regarding yours / research on pressure zones / etc? Been looking for useful data, but haven't been able to find much on the 8, though there seems to be quite a bit on the miata...

I am using a Carbon Vented hood from Seibon, Don't have any airflow data I am afraid...just observations from the hood

I was going to use a smoke grenade in front of the grill....but though better of it ;)

aahh i see. Which did you opt for? TS? TSII? TT?

TS i think ..been a long time since I bought that 😊

so I lied about not going out in heat anymore. Looks like I'll be out this coming weekend in 100+ temps again, ugh. Saturday's forecast calls for 112???

I added some copper pipe insulation on the top and bottom of the radiator put air through the radiator, left the sides so that some airflow gets through, and am working on getting the Singular hood louvers installed to create more of a pressure differential from the front to rear of the radiator.

Fingers crossed!

Do let us know the coolant temps once you get the hood louvers installed. Always wondered if it really made a difference...

Hi pcs, I'm curious, which track are you headed to this weekend?

Also, I would like to help you get your temps further reduced, would you email me a few underhood pic's of your current setup when you have a moment.

Thanks pcs, look forward to helping, Scott

was going back through this thread and missed this. Was running FL-22 originally, but when I changed the radiator, didn't remember to use FL-22 and ended up with about 75% distilled 25% green coolant (not sure which one anymore).

Stock fans, yes.

Well I have finally bitten the bullet and ordered one of these. Will post some experience, data, etc when I get it running.

^thanks

Thank you Dragon, we appreciate your business! Sorry if I missed it, are you running the stock fans, pulleys and thermostat currently?

Everything stock right now, but AC removed and it is an s2 motor, so s2 water pump.

Is it an S2 model or did you do a motor swap into an S1?

Hey Guys, I wanted to let you know we just finished up another build run of these and have three units not spoken for as of yet! Thank you for your business and support, Scott

Hi guys,

Spring will be here before you know it and we have been getting emails from guys who are prepping their cars for the better weather and a new season of motoring! Emails regarding our dual pass radiator have been coming in and we are currently in a build run, if you have been putting off picking one up there's a couple spot's left in this next run.

The last one in stock is being shipped out to Ric Shaw Racing in Australia for a full on S2 track car build he's putting together. Thanks Ric! :wavey:

You know who you have to call 😎

I have yet to install mine and would be happy to take some measurements of it if needed.

You already know this of course, but it's BIG :) Troubleshooting this right now...

I just inferred you got the dimensions from Scott already, so you know the size of it. Troubleshoot was a bad term. I just mean it's get dirty install time. i went with the performance fan at the same time and have a tip from Scott just in case we need a touch more clearance to the cross member.

EDIT: it's in, just need to foam.

We currently have a just a few of these remaining in stock and ready to ship!

If you have any questions guys don't hesitate to ask!

Thank you, Scott

Anyone have photos or diagram on how to connect the fan assembly as it does not have the standard connectors?

Perfect fit

Finally got around to wrestling this bad boy in with the stock fans and intake yesterday. Just need to find a pipe to connect the reservoir tank now and hopefully all set.

Big thanks to escapedan because I'm pretty sure I would have given up and ordered some new parts without the pics he posted earlier in this thread.

A few tips:
1. If you don't have an assistant, get one. Otherwise be prepared for a good workout as you lift this thing in and out of the car 6 or 7 times.
2. In place of an assistant, an axle stand can be used to support the bottom of the radiator.
3. You are going to need to trim the oem fan shroud down some. Start with the right hand (looking from the back) edge and then a few other edge pieces to get it as flush to the radiator as possible.
4. You will need to trim some of the fan shroud to get the upper coolant pipe on. I recommend doing that now so you don't forget and then have to take the thing out one more time just when you thought you were almost done (guess what I did?)
5. It might be possible to do without completely removing the passenger side fan connector leg that I did. Instead, try shaving it down with an angle grinder, leaving most of it in place. I did this on the 2nd one. I didn't remove any from the passenger side, but I did shave some down a bit.
6. You will also need to notch the left and right edges of the fan shroud to accommodate oil cooler pipes and the front of the fuse box.
7. I don't drive the car any more than I have to between track events, so I'm not too worried about losing the pipe through which the fans pull air through the ecu box. I guess I will find out how well it and the small battery I have get on with the heat when the car is stationary.

Assuming it all works when I get the final pipe on, I'll be testing at LS next week :-D
