Thanks for heads up 1lowdiesel!
The Extruded Tube Design core we use is the highest quality core design available, you do not need to be an engineer to appreciate the difference between this design and the others...
Looking at that cut-away image not only shows a clear flow advantage but also shows a reliability improvement. The extruded tube design will eliminate heat distortion that is typical of the bar and plate and stuffed fin and tube designs. When using these intercoolers in applications that create more heat and pressure than they were designed for increases the heat distortion factor resulting in failure. These bar and plate designs are not engineered to see 500 degrees and 70+ PSI of boost!
We have been using these intercoolers in the Dodge Cummins powered diesels for a few years now in applications over 800HP and I assure you the 150-200 degree drops in EGT's are real! I know we are talking about the Duramax here but the results are the same.
I run a 03 Dodge with an A/C condenser in front of the cooler and I see noticeable differences at the track. My X2 records minimum and maximum values and after installing the BD Cool-It Intercooler the temps were about 10% lower on average... not a huge drop but never the less still a reduction!
A typical intercooler using bar and plate technology will usually net a 3-4 PSI boost loss, with the extruded design we see less than 1 PSI boost loss. Picking up 2-3PSI of boost will also contribute to lower EGT's... again not huge gains but when we are talking about the track, everything helps.
Now that covers about 5% of the target market, the other 95% that are using these trucks as a work horse see tremendous benefits in everyday towing, especially at altitude!
One more thing I would like to add that ties in with the A/C condenser topic....
The BD Cool-It Intercooler flows better from front to back not only from left to right. The design of the tubes and the fact that there are more tubes that are narrower not only allows for better cooling of the charged air but also result in better flow through the front of the cooler. This results in lower coolant temp allowing more air into the transmission cooler, the radiator etc...
Like the slogan says..."when you know the difference, you will choose BD"
