Hey, I was thinking of going the dual pulley route eventually and I hear some companies say you need to upgrade the charge cooler. Now do any of these companies like Viezu and Eurotoys have any temps recorded before and after the stock charge cooler was changed? I know they are 30 % bigger or so but want to know if anyone has any actual data.

 

My understanding is that un uprated charge cooler isn't strictly speaking necessary. I unfortunately don't have any data on which charge cooler from either of the companies mentioned is best. My guess is they're probably very similar. Having said that, I will be going with FI Interchiller for my charge cooling needs. This heat exchanger taps into your car's AC system to supercool the fluid going to the TMIC for the supercharger. It's a lot more complex than a standard heat exchanger but the temperatures can get below freezing and it is hands down the best way to combat heat soak if drag racing is your thing. I hope to get started on this project next summer, but if you want to know more you can check out their website. Their FAQ section is amazing and very thorough.
