The complete charge air cooling solution for Porsche 911 992 Turbo / Turbo S
Bigpack Ð intercoolers and charge pipes sold as a unit
Alongside our intercooler kit we also offer various of other products for the Porsche 992 In this bigpack we give you apart from the intercoolers themselves our intercooler pipes and silicone hoses for improved airflow that will last over time
If you ask us this is as good as you can make an intercooler kit for this platform No rock has been left unturned in our quest for maximum performance in any given section of the system The starting point is the cores from renowned Garrett Motorsport these are incredibly wellmade with thin and stacked fins exactly according to our specification in the weighing of cooling and airflow The end tanks are made from thin cast aluminum to keep the weight down and still utilize airflow To accommodate the thicker core we replace the air guides with carbon ducts made from the best quality And to remove bottlenecks throughout the system the intercooler connections are made bigger and come along with do88 silicone hoses designed with soft sweeping bends We have not made any sacrifice or compromise during this development Ð behold the results

Complete set of charge pipes containing powder coated pipes high temperature silicone hoses and hose clamps of higest quality
Background
Earlier versions of the Porsche 911 have their intercoolers inside each rear fender with a ypipe uniting them both before the charge air reaches the inlet manifold The 992 has a different setup entirely The intercooler and ypipe are now combined to a unit that sits beneath the rear wing The ambient air is pushed via channels from the rear window into a scoop on the decklid and onwards through the intercooler core for optimal heat transfer Looking at the construction from the side this configuration really makes more sense but is also more demanding for us a performance cooling manufacturer To be able to fit a core with greater volume and surface area we had to develop new carbon ducts to allow the increase in thickness We are very happy to have taken our carbon production to the next level with this product the fitment and finish worthy of an icon as the 911
Cores from Garrett
The cores are BarampPlate made by renowned Garrett Motorsport Quite frankly they are as good as they get Thin and stacked cooling fins give a dense construction providing very efficient heat transfer The core measures 105 mm 4Ó and are exactly as thick as you possibly can make them for this application The air is distributed to the entire core via free formdesigned cast end tanks Designing these was a significant undertaking that concluded 3Dscanning CFDanalysis and 3Dprinting many times over until we had a finished prototype We chose as usual to use cast end tanks as they allow shapes that CNCmachining cannot replicate and to us function always conquers form Maximum airflow supersedes the bling factor The tanks are made with machined 70 mm 275Ó connections to enable high outputs To pair with these bigger connections we also include silicone hoses Both cores are united by a central outlet tank towards the inlet manifold utilizing machined connections and meth bungs
Ambient air guides made from carbon
The air guides are made from vacuum infused prepreg carbon and all pieces come with fastening grooves for the air channels just like the OE bits As complex as the shapes are we still guarantee perfect fitment They come with proper rubber seals where this is needed to prevent the cooling air to escape pass the core
Aluminum pipes
In the bigpack we also include the do88 charge pipes Ð a distinctive improvement that replaces the OE hoses Made from mandrel bent 63 mm 25Ó aluminum pipes finished in a tasteful satin black powder coating they provide better airflow and sustainability over time Included with the pipes are four silicone hoses of which the turbo outlet hoses are made from a hightemp spec material rated to 240C 464F continuous temperature The hose clamps in this position is of the Òconstant tensionÓ type meaning they will compensate for thermal expansions in the material
Performance
When it comes down to performance the do88 intercoolers significantly reduce the intake temperature In the graph found in the product pictures the difference towards the OE 992 units is presented The data is collected with an AIM race logger under 4 consecutive runs in an immediate sequence on a closed airstrip Full throttle accelerations between 50250 km/h 30155 mph carried out in a Porsche 911 Turbo S 757 hp with updated software and exhaust Hard braking no cooldown in between just full pull five times The rear wing was in its upper position all the time
The test was conducted in the following manner
Firstly 4 runs were made with the car equipped with the 992 OE intercoolers Stop fast change of parts to the do88 intercoolers Shakedown for a few minutes and then five runs made in the exact same way as with the OE parts The decrease in inlet air temperature is significant peak delta is 12C 216 F
Cooling is important and so is airflow After many hours in the development refining the end tanks and choosing a core to meet our demand the result is an intercooler that is much more efficient in terms of heat transfer as well as airflow Using our inhouse flowbench Superflow SF1020 Probench the airflow is verified for both the do88 intercoolers and the OE 992 units What you see is what you get Ð true performance
