Hi all,
As the engineering report states, ambient temperature on the day of the testing was 72*F at 29% humidity. The 10*F temperature drop mentioned is an additional 10*F drop over the efficiency of the stock core, IE: (stock inlet temp - stock outlet temp) - (mishimoto inlet temp - mishimoto outlet temp) = -10*F. The engineering report also states that the truck was tuned for testing to better match what many of our customers run; I can try to get the details of that tune for you all if you'd like.
Both cores are very efficient at removing heat over short periods of load, with the Mishimoto intercooler bringing outlet temps down to <10*F above ambient temp throughout the testing and the stock core rising to around 10*F over ambient on the last run. While a 10*F additional temp drop is not huge, the main takeaway from the engineering report is the fact that our intercooler was much more resistant to heat soak under load than the stock intercooler.
Throughout the testing, there is an upward trend to the outlet temperatures (as there would be with any intercooler, hotter inlet temp = hotter outlet temp in scale with the core's efficiency). However, unlike the stock core where outlet temps increased exponentially under load; the Mishimoto outlet temperature does not deviate from the trend line, indicating a high resistance to heat soak. That means that you'll be able to push the truck longer under load without loosing power, where the stock intercooler would begin to heat soak and lose it's ability to remove heat from the intake charge. This would be true whether or not the louvers were removed as the heat rejection properties of the core remain the same.
Wagner's graph is a good example of an overall intake-charge temp comparison over a run, but it does not account for the intercooler's ability to resist heat soak over long periods of load.
Feel free to let me know if you have any other questions,
-Steve

I mean if you're doing dyno pulls with cooldowns, at least do it in 4th or 5th gear so it's a longer pull. And yeah if you can get the details of the tune that would be awesome. I'm considering a purchase of this thing when it comes out, but i need to know it'll actually be enough better than the stock one to resist charge temps coming way up over the course of a multiple gear wot pull.

Thanks for replying but I don't feel this is an either or situation. It's important to compare it properly. Heatsoak is but one facet of the performance.. How's it do under multiple gears under wot at speed? If you can show it being significantly better than I feel like you should...

We did not design this intercooler to provide massive temp-drop, as the stock intercooler is already very efficient. Rather, we focused on creating an efficient intercooler that had a high resistance to heat soak and thus maintained that efficiency throughout high-load situations.

Ok, well this is a 3.5L probably wringing about the most the stock turbos will output tuned on e50. So i take it that means i shouldn't use your intercooler judging from that response?
I know yours will be very superior to the stock one, but i need one that's efficient enough to cool to near ambient when pushing the stock turbos pretty hard, so i guess i'll get one of the other ones that have more volume and surface area. Thanks!

Keep in mind that a thicker core doesn't always mean a more efficient core - as air moves through a thick core, it heats up and looses its potential to pull heat out of the core. Eventually adding thickness to a core does nothing more than add weight and increase pressure drop.
Are you drag racing the truck and do you know what your IAT's normally are under the conditions you're looking to cool? The owner of our test truck is also one of our fabricators and drives the truck almost every day as well as drag races it. He's noticed a big difference in IAT's pushing the truck pretty hard, but I don't have data to show backing that up. I would think that on the stock turbos and E50, your intake temps wouldn't be so high that our intercooler wouldn't provide a significant improvement. Below are our surface area and core volume that you can compare to any other intercooler you may be looking at.
Thanks,

Hey everybody,
Just wanted to give you all a heads-up that this pre-sale will be ending tonight, so if you're still debating ordering, now is the time!
Thanks,

Hi all,
The pre-sale has ended for this intercooler. Thanks to everybody who hung with us through the delays, your orders should be shipping out soon. For those of you who would still like to order the intercooler, you can do so from our website or keep an eye out for discounted prices on our distributors websites!
Thanks,
