Eagerly waiting for your meticulous test results.

I found this! Lets see how the competitors compare.Also in! Waiting to hear about this guy before I just up and snag the "competitions" product.
Interesting feedback Justin! Thanks for being transparent about the review. What do you think of the stock heat exchanger? Does that mean that the stock unit is as efficient as it can get?
Thanks for the information @kern417 . Much appreciated. Do you have any experience with circuit track type racing with this heat exchanger on your rig?I don't have a mkv, but was asked to add some B58 data. I have a 440i with a supra HPFP and custom E85 tune from F80Paul. I'm estimating that I'm between 450-500whp
Method: 3 back to back pulls from ~40-140, starting in 3rd at 2500rpm and running 4th out the redline (manual transmission). I truncated the data to be 3000rpm in 3rd to 6900rpm in 4th. I know it's not perfect but I think the general concept is solid.
Ambient/IAT Delta = Difference between ambient temps and IATs
Intercooler Delta = Difference between intake temps before and after the intercooler
https://datazap.me/u/kern4179/stock-v-csf-iat?log=0&data=
My main takeaways
1. The Amb/IAT delta are similar, but the temps were 20F hotter for CSF pulls
2. The intercooler delta increased with the CSF radiator despite hotter ambient temps (made the intercooler more efficient)
3. The rise in IATs during a pull is reduced with CSF
4. No matter what, temps increase in back to back pulls - unfortunately I couldn't get the super flat temp curve that was advertised. I agree with Twisted that it depends on how hard you're pushing the turbo.
I don't do track days in this car, so unfortunately I won't have any data in that department. I could log some backroad runs but I never push as hard on the street. That was my goal with doing the back to back pulls, since at a track you're always either on the gas or on the brakes. I would suspect that you'd have a lower equilibrium temperature, but no space to test it out.Thanks for the information @kern417 . Much appreciated.

cool, should helpPlaced an order for this through @Titan Motorsports, should release first week of July
Doing this alongside a Pure800 on 93 and will see how it goes
140+ IAT's here will need all the help there is
