HIGH PERFORMANCE TURBO DOWNPIPES BY HPA

Maximizing engine performance starts with engine heat management. Turbo charged applications generate extreme amount of surface heat at the turbo charger that radiates directly into the aluminum head reducing the engine ECU's ability to advance ignition and fueling maps due to detonation. Besides strict global emissions standards resulting in restrictive catalytic converters being installed, oem engineers must factor global restrictions on minimum clearances for front impact crash test results when packaging and designing the factory turbo downpipes.

Each HPA downpipe application is designed around emissions compliance requirements, thermal radiation/contact surface clearances and engine ecu software framework. The calibrators drive the hardware demands to ensure that the dimensions and catalytic converter requirements are calibrated within the spectrum of the ecu's capabilities. The goal is to reduce the heat at the mounting surface of the turbocharger to the aluminum head. When the balance of heat reduction has been realized, the calibrators can create a fuel and ignition mapping that will ensure that the tailpipe gases are clean and the boost levels can be raised. Heat is the enemy of HP and even your stock mapping will benefit form a more fluid design of exhaust gas discharge.

The average OEM 63mm downpipe diameter coupled with a restrictive catalytic converter and varying angles don't allow for ideal flow specifications and result in higher back pressure at the turbo forcing it to work harder and generate excessive heat.

HPA's resulting 3" downpipe is a fabrication assembly designed around functionality and durability and proudly manufactured in Canada. .063wall T304L stainless mandrel tubing is precision tig welded and Argon back purged for an ultra clean look on the exterior and a perfect clean weld on the interior. Our CNC formed hanger and laser cut flanges mate this assembly to the chassis and will withstand the thermal conditions the turbo will generate. Our flex couplings feature an internal stainless steel interlock liner that facilitates smooth flow of high temperature exhaust gases.

HPA EA888 Gen 1 and 2 street downpipes come standard with our 100C high flow cats while the new MQB GTI and Golf R come standard with our 300 cell metal cat, the same quality of cats used on all HPA twin turbo high performance vehicles.

Nice product
Color: Gold-aa
when having guests over, it's nice for each one to use their own towel instead of having a 'community' guest towel, or those fancy ones that people feel guilty using. This solved the problem.

Poem by Luci Shaw and Illustrated by Ned Bustard
Format: Hardcover
A wonderful book for all ages! Thank you to InterVarsity Press, Luci Shaw, and Ned Bustard. The book ends with A Note from the Author. Luci Shaw writes, "And if this book inspires children to write their own poem or story, or create some art, both Ned and I would be so very pleased!" Thank you.

Colorful and Vivid
Format: Hardcover
This picture book features vivid cut-paper illustrations that visualize the concrete images in the poetic text. I found aspects of the poem abstract enough that I'm not sure if young children would connect with it, but they can enjoy the rhythmic language and emphasis on phonic sounds related to the letter "O," even if some of the abstract thought is beyond them. The vivid and colorful pages will definitely appeal to both children and adults, and the book has a nice message about hope and God's love. Throughout the book, the letter "O" appears in different colors, and the note at the beginning of the book encourages children to find things in the illustration that start with that letter. Children could also count how many times the letter appears in the text. This would be a great choice for Christian families, churches, and Christian preschools, and would combine very well with a cut-paper craft for kids to do. The author's note also includes some open-ended discussion questions that adults can use with children.

Our Creative Designer Invites Us to Hope Fully in Him
Format: Kindle
Because I’m spending time now in the public schools, I’m seeing how desperately our children need an infusion of hope, so I’m thrilled to share an InterVarsity Press collaboration between poet Luci Shaw and illustrator Ned Bustard in which hope and joy meet. Little meaning-makers will be entertained by whimsical images and then gently introduced to our safe haven of hope, “the center of the loving heart of God.” The O in Hope grows up with your child, for toddlers can point to the multicolored O‘s on each page while older children identify the O words and play I SPY in search of critters beginning with the letter O. Both poetry and hope are meant to be spoken out loud, so wise parents who are determined to “hold fast the confession of our hope without wavering” will find strong support in words and images that point to the creative Designer whose faithfulness invites us to hope fully in him. Many thanks to IVP Kids for providing a copy of this book to facilitate my review, which is, of course, offered freely and with honesty.
