It seems to me your only problem here is the fans are not pulling the amount of air needed in stop and go traffic to cool your engine down.



That or you have issues with your cooling system, air bubble/leak/stuck thermostat/bad water pump among others.

Apparently stock fans wont fit with my setup so he wanted me to get a 9 inch fans wasnt even sure why but yeah wouldve gotten an 11 inch

Do you have a shroud? What is the model of the fan.

What is the flow rate comparison.

My experience is OEM fans are typically better than any "slim" fan.

But, check the flow rate.

There is lots of info, I couldn't find the OEM fan flow rate in my 30 seconds of googling

What happens when you turn your AC on?

I don't have any flow rates but the Versus Engineering who posted that built a radiator and slim fan combo that supersedes oem cooling. So

The guy says he has 9” fans. I don’t know what the stock fans are in diameter or the brand or if they have shrouds, but it is entirely plausible that he made a downgrade.

This?

Note:
1. Designed for motorsport? Not stop start traffic
2. Car on website has bonnet vents

My take:

1. Whilst designed for motorsport may make it sound sporty, there is a huge difference when it comes to what works on a track and what works on the street when your stuck on traffic and not lapping at speed.

2. Op does not have bonnet vents.

My old R33 with a larger radiator and OEM clutch fan would still see much higher temps than what I liked on the street, track work was fine due to the airflow thru the radiator when at the track. I fitted a vented bonnet (pics are my old boat after I had just sold it) and my temps improved massively both on the street and on the track.

There's lost of people running them.without vents. Nobody will convince me that oem is better than spal fans.

Which one?

Just need to find OEM to prove me wrong.

When you do I will stand humbled, until then....

And what size does the OP have?

[Joveen]

9" fans. Not sure if they are spal fans. If it's the mishimoto one I know those are 12" but not spal.

I'm talking from experience my dude.

Stock fans are able to cool down an LS swapped 86 which generates more heat than stock turbo engine. While the super slim Spals that are included in all of the slim fan/shroud packages for this car cannot keep up.

I actually have a swapped 86 and have experience with it. With my setup stock fans did not fit and I needed to upgrade the shitty slim spal fans (the ones included with the Fullbown slim fan shroud kit which they claim it 1100+ cfm and I had found them to be 900 cfm) to 1328 cfm Spal fans. Still, stock fans were able to cool down the engine better than the 1300 spals, but they did an acceptable job.


I have a friend with a swapped 86 and stock fans who moved the radiator forward in order to fit the stock fans, and has never had any issues with cooling on his swap.

Granted, of course, no all Spals are made equal. There are larger/more CFM Spals that will be better than OEM. But given the envelope of the usual slim fans/shroud kit used for this cars, they are not better than OEM. In order to fit my 1328 CFM spals, I needed to increase the fuse from 25-30A, becuase they used a bit more current than 25A. Getting any bigger Spal that could "beat" the OEM fans, would require a larger relay kit/wiring.

The Verus kit huge improvement is because they use a super efficient radiator and like a previous poster said, racing is not the same as stop and go traffic in high heat. stop and go traffic basically the fans are by themselves to remove heat, unlike racing you have forced air coming in and cooling the radiator.


The more you know....
