So on track I seem to be overheating on my 6-
7th lap. Wondering if anyone has upgraded thier
Radiator if so what size radiator..i tried to order a koyo
36mm part #v2577 but was told they only can order
The hh version which is 48mm..wondering if it will
Fit with stock fans..
Any other options
For what its worth i will not install any
Mishimoto garbage on my ride..
Any one?

 

Might fit but will be tight.

And 7 laps FI isn't terrible. Most people have to run cool down laps after 4-5 laps especially FI will all cooling mods.

But bigger is usually better but also think abou getting a higher flow bumper. Sometimes the rad just work over time cause it's not getting full flow through them which is how they work. No air no cool essentially.

Fans aren't meant to chill, but maintain and save from over heating mostly in mind traffic and commuting. Let alone full track hot laps.

 

Your only chance to getting that Koyo 48mm radiator to fit with the Vortech is if you get slim fans. Look around, the 36mm should be available somewhere.
