damn 108, it's 94f today in NYC and I felt a bit hot.

I have a feeling we might hit with over 105 this year in NYC. ahhh. world is ending ! panic bitches !

 

And that was at lunch time. My GF and I went to dinner at about 6 and the temp was 110F in her Mazda 3S.

 

word its been averaging 96* up here.

 

Hey 9k. New setup looks great. I'm having some cooling issues. Just wanted to see if I could pm you and pick your brain.

 

PM away

 

So now that we have the install and review done, here's a Group Buy! https://www.rx8club.com/showthread.p...13#post4016813

 

nice DIY, but the OP fails WRT resulting operational data

 

I do have some logs but honestly doing a comparison to the stock logs I took previously is difficult to post up in a way that most will make sense of it. I think this radiator is as good or better than the OEM but the Mizu fan shroud is not as good (still works fine just temps in traffic are about 10F higher) at low speeds and in traffic. I will be installing a new OEM shroud and fan pack soon and then I want to compare everything. The bottom line though is that so far everything works and fit pretty well, even in these extreme temps we have been seeing.

 

I wasn't so much knocking you as egging you on ... and I was wondering about the effectiveness of that fan kit over the OEM setup which has a pretty strong flow performance rating

 

The Mizu fans have thinner blades which would seem to allow more flow at speed. But when standing next to Hoss-05's car after a drive there is definitely a lot more noise and a lot more hot air being blow out from under the car than you feel with my Mizu fans. I'm not sure if it means anything in terms of cooling but the Mizu fans are very quite compared to the stock fans. I should have hooked up both fans assemblies out of the car and done some testing. Maybe I will do that one of these days since I will have the car apart anyway.

I should have a Mazmart radiator, pump, thermostat here pretty soon for Hoss-05's car and I am curious to see how it works out. I will have logs from his car as well.

 

9k: any recommendations on sealing up the bottom of the radiator? After putting new sways in i noticed that the foam seal has become brittle and blown away as well. Thanks in advance!

 

Yes, at Lowes or Home Depot they sell rolls of square 2"x 2" x 2" x 2" foam insulation. You can use double sided tape and attach it on to the bottom of the rad. When you put the tray on it will seal up good.

 

thanks! So im guessing the other foam tape you used wasn't as good?

 

It was okay but you have to stack it. It works on the aluminum rad but not as good on the factory rad because there is not a flat surface.

 

is it anything like a Mishimoto rad? only ask as i upgraded my stock rad in my gsx before i sold it, and used there fans/shroud and noticed a -10/20deg difference althou it sounded like a jet engine on high lol...

I like the install, have you done ducting work? as i see what i think is the Ac condensor? in front, helping air threw that and extra around would help (not sure how the front is laid out, as i have yet to tear mine 8 apart lol) but with a FMIC or AC condensor ducting helps, well it did with the gsx, -4deg extra drop.

 

Updates?

 

Currently my baby is on jackstands awaiting my fresh built motor from Pineapple Racing and my newly upgraded and Greddy turbo by AMR. I decided to go big and do everything as best I can within my budget. Most would knock my choices on cooling but I think the Mizu will handle things just fine. Stay tuned, my car should be finished soon.

 

Got my Mizu silicone hoses in!! Thanks www.sparkplugs.com!

Did you make that aluminum undertray?

 

Yeah I like the write up for the DIY. I had put mine in and for me installed is simple only thing I disliked like I had to make a few adjustments to make it fit properly. Plus this is a nice radiator I got mine with rad and shroud for cheap. But the construction on the welds are nice so I would recommend this to someone who Needs a replacement radiator and fan

 

So far so good with my Mizu fans and radiator on my new engine and turbo setup. But I have not gotten into boost during hot weather and that will be the test.

The workmanship and fitment on the radiator was as good as I have seen and I have a brand new Mazmart (Ron Davis) unit in the garage that I compared it too.

My setup is not really comparable to most but the radiator is definitely a great upgrade if you need to replace your factory rad and or fan shrouds.

 

No problem, I'm glad if it helped.

 

Update:

One of my Mizu Fans failed. I have been having some intermittent high coolant temps and I really could not figure it out but I guess the fan was working just not all the time. I noticed over the weekend when it started getting hot that one of them was not blowing very hard and then today after lunch it was running warm and when I checked it, it was dead, not blowing at all so I only had one fan in use.

I had already purchased this Flex-A-Lite setup to replace the Mizu's after I started seeing issues and found out they are only rated at around 1800CFM. These bad boys flow around 3,000-3300CFM (spec differ from the online specs and the catalog) which shoudl be more than enough.

Here it is test fit on a Mazmart Rad Hoss-05 is waiting to put in.

Rubber seal all around the inside to seal against the radiator.

I will replacing the Mizu fans with Spal units that I will install on the Mizu shroud.

 

Why did you use this instead of the spray insulation?

 

Because spray insulation expands?
