Ok, I know everyone on this forum is all "get a Godspeed its incredible" but what are peoples opinions of the koyo 55mm? and more interest to me.. has anyone had any experience with the new Springfield Dyno Spec Miata Radiator? its supposed to cool better and more then the koyo... a test they ran the car never went over 170* for a 34 min test... the koyo ran the same test and hit 190*
Thoughts?
I know its $600, but id rather do my re-route and spend the 600 and never have another heating problem then trying 5 different things and never get it right..

For 600 bucks, buy two Godspeeds so you have a spare, a pair of electric fans, and Mega Squirt so it will turn them on and off. Should run you around 600 bucks.

Seriously, what's your power goals? What do you plan to do to this car? Most conclude the size of the radiator isn't what matters (after you have a big one), it's getting air through it. People who track their cars run different hoods, under tray's, high performance fans and shrouds, etc to get air through the radiator. I'd have to say the GS radiator is plenty big for 99% of the peoples needs on this forum.

id like 275-300hp and i overheat like a beast... thats one reason im doing the re-route... but it doesnt seem like it will be enough

if you have the money and want to spend it on a radiator, go ahead man...
other than radiator, what else will you do to prevent overheating?
fans, shroud, ducting, extractor hood, re-route? all those things help in keeping temps down
the GS rad has enough capacity, more than you need, its not the best radiator out there, but how much better do you need, $600 better? id say no.
most people here want reliability and power, we all try to save a buck or two, but will not do so to sacrifice reliability, iow just like you i assume...
the GS will be enough if you do other things as well, things you should do with the $600 radiator as well
its your choice, most here use the GSb/c of its lowcost and high capacity

Yea, IMO you don't need that 600 dollar radiator. Give us details. Do you daily drive this car, or is it a race car that's gonna see hour long track sessions? Don't just answer this question in a single choppy sentence with no capitalization, punctuation, apostrophe's, or clarity. Explain yourself clearly! Keep up the crapy sentence structure like Whaam and people will ignore you.

Are you trying to save a buck, or do light your cigars with 100 dollar bills? Throwing parts at a car is not the way to solve your overheating problems, you have to make logical reasonable decisions. IMO, blowing 600 bucks on just a radiator is crazy unless you've done every possible thing to increase airflow through the radiator and your 400whp beast just needs a little bit more cooling for those long track sessions.

I have had the Ron Davis radiator now for years and have never overheated....haven't even come close. Worth the money for me.

What's wrong with a 190f coolant temp? The on temps for the OE fans are good indicator of ideal coolant temps. The engine actually makes more power around those temps than colder (or hotter).

highroller101

I am in the process of a coolant re-route going intake side. I have ducting and I have been reading up on oil coolers... is this a decent one? http://www.good-win-racing.com/Mazda...t/10-1001.html
Fans are in parallel right now, but don't really need them because the car is almost never on the street(only to get to the track) I was reading up on M2's mini scoop extractor, and it seems great and I may invest in one myself. Like I said, I dont want to buy things more than once... I have done it enough, so I just want something that I am never going to have to fix ever again.
But if its just as good, maybe Ill consider it since the price is so much different

highroller101

What does IMO mean? This is a track car, rarely used for DD, it sees 3 sessions in a row of 30 min each on a rough day, but it needs to last at least 40min of track time.

I want the cure of overheating! haha. If it cost me a $1000 I dont care as long as it works I am also talking to Whaam about his front bumper because I think that will help with more flow also. I am looking for 300whp and beating the crap out of it on the track.

highroller101

Link? What are the specs?


PS... I read in a post that there is a dual core, dual pass rad...? This sounds intense.. Has anyone heard of it/ run it? If they have could they also supply a link? Thank you!

highroller101

There is nothing wrong with 190. I am more concerned with 200+ coolant temps. Once the car starts to overheat, my Link shuts the power pretty much off and there is no power left.. I stick it in 5th gear and drive around the track half a lap and the coolant is back to normal

During controlled dyno tests, we have seen 15-20 degree drops on intake air temps.

that truly is an incredible radiator I'm going to assume they're talking about air flowing through the rad. But you gotta think if it's dropping coolant temps that much, then it must be exctracting lots of heat from the coolant... and where would that heat go?

highroller101

I think they meant coolant temps. Because I saw that on JVTR's 3 row rad and I laughed.

Here's the link to the Ron Davis radiator I have.

and

Here's the link to the dual core radiator.

FM is where I got mine, but looks like they switched to PWR and dropped the twincooler as well.

Is that dual core rad, also dual pass? I think it was in M2's post he was talking to someone and they said they had a 4 row rad and they and he explained it as dual pass and dual core.. not just dual core.

Thanks for the link!

Ive got the Koyo rad for mine, after speaking to some people over here running bout 280hp they said with the bonnet lifters, koyo rad and 16- 19 row oil cooler their running temps are fine but its cold here most of the time anyway.

highroller101

off topic.. Vash, do you play xbox live?

highroller101

Its been 100 degrees out on track days... and that really kills me. I am looking into a oil cooler.. I supplied a link to one I'm looking at. But im not necessarily sold on that one if anyone has a better option.

i'm actually using the dual core one... not from FM but from Koyo... the OE replacement for the automatic? it IS better cooling but i'd rather just buy a godspeed

Here is M2's post.. Ps. M2 could you give pics... On this link they dont show up. https://www.miataturbo.net/forum/showthread.php?t=4530
