Being pleased with our design in comparison to the stock unit, it was time to put this radiator to the test and see how the improvements would impact cooling efficiency. The first true test for this radiator would be fitment. Although this product was designed based off of dimensions from the stock radiator and the engine bay of an E36 M, we still had yet to drop this unit into a vehicle to ensure that all components bolted … Continue Reading ››
Alright, the prototype is in and ready for comparison against the stock unit. To show how much different this radiator is compared to our current offering, we would also be bringing in one of these radiators to observe the differences. First, let’s take a look at the stock radiator we have. This unit was used to pull critical fitment dimensions.

We are huge BMW enthusiasts here, myself included, and we have found a gap in … Continue Reading ››
Finally, we made it to our day of testing! We had previously confirmed fitment and made a few minor adjustments to some external end-tank features to improve coolant flow and ease of installation. A member of E90post was kind enough to lend us his vehicle for this round of testing. This 2007 sedan was equipped with a manual transmission, JB4 software and an intake. This vehicle would be ideal for collecting testing data, we have found that the “Average” E9X owner has … Continue Reading ››
Now that we have a prototype E46 radiator, what should we do with it? Test it of course! The data for this entire build is based around radiator testing. Check out the report from our lead engineer.
