The factory B4x/B58 heat exchanger is not built to cater to the rigorous demands often associated with a modified build. The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast.

The Dinan B4x/B58 heat exchanger for the F2x/F3x chassis assists in mitigating these issues with a more robust core (48mm thick Dinan core vs. 27mm thick OEM core) that wields 78% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness requires unique "L" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15° IAT delta recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment!


ENDURANCE TESTING

Charge Air Temp Reduction, or Intercooler Temperature drop (Intercooler dT), is a measurement of the temperature drop across the intercooler (inlet temperature - outlet temperature). For this testing and data presentation, the measurement was taken at the end of each pull (~100mph WOT). The end of the pull was chosen as it generally represents the highest load on the charge cooling system. The charge cooling system has two parts, the intercooler and heat exchanger. The data shows that by implementing the Dinan heat exchanger, with the OEM intercooler, the charge cooling system pulls more heat from the intake air (lower IAT's) and performance decays slower (longer time on track before cooldown required).







Features:

  • Average of 8° reduction in IAT's with a maximum reduction of 15° over 15 successive WOT pulls
  • Reduces the tendency to heat soak / go in to limp mode
  • 48mm thick Dinan cooler vs. 27mm thick stock cooler
  • 78% more cooling surface area and volume than stock
  • 100% TIG welded and pressure tested
  • Installation hardware included (inclusive of xDrive specific transmission oil cooler brackets)

Great for my Quilting!
Format: Hardcover, Format: Hardcover
I bought this book at launch and it has pretty much become my “bible” for Final Fantasy pixel art. I sew and love making nerdy quilts so when I saw this, it was a total insta-buy. It showcases so much original art as well as newly designed sprites (for both older and newer games). I honestly didn’t know about the newer games being designed as sprites so when I saw this, I immediately got to creating. Beyond this being a great pattern book for pixel quilting, I loved seeing a piece of FF history we don’t get to know about. Also loved the interview showcased. A good book for any Final Fantasy lover collection!

A great book for a fan of the early final fantasy series.
Format: Hardcover
I love this book! I grew up with the NES and this brought back a lot of memories of how as a kid I would get lost in the creativity of what developers of these games made with only some blocks. I love pixel art and this book is great if you enjoy making your own and admiring the work of someone else's and seeing their imagination from some truly great games. This book is small in size but is perfect size to show blown up images of final fantasy pixel characters and creatures, also of places from the games. Also having final fantasy characters from beyond the Nintendo/SNES was a really cool surprise to see if they had been made in that era.

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.
