the NEW CSF Built Supercharger Intercooler Bricks for the LT4 Engine #8366
Another weapon in our FIGHT against heat soak!
WE ARE TAKING PRE-ORDERS FOR UP TO 25 other sets that are EXPECTED TO ARRIVE LATE NOVEMBER. FREE SHIPPING ON ALL ORDERS + BUNDLE ITEMS for a VERY LIMITED TIME ONLY !!!!
For those who know our story, we have been laser focused on helping our beloved LT4 owners get the most out of their OEM 1.7L blowers since day one. Getting more power out of these blowers is easy, but mitigating the intake air temps is not. Which is where our focus began when we started to develop what would soon become our Stage.III Super Charger Cooling Package. Armed with lots of auxiliary diagnostic tools and sensors we set out to maximize the effectiveness of the OEM HX System. We achieved this by removing as many restrictions as possible, adding capacity and improving the hardware responsible for thermal conversion. The result is a HX system that helps the little CWA150 pump flow a whopping 100% more gallons per minute, while adding 815% more fluid to help fight against heat soaking the fluid responsible for getting heat OUT of the intake charge.
And that brings us to the final piece of the puzzle. The supercharger bricks.
For those who have fiddled with the OEM blower / bricks, you can agree that they are not only small, but Eaton did not give us much room to expand their size within the 1.7L casting. With the rest of our system working near peak efficiency it was time turn our attention to the pesky bricks. After a few weeks of designing different size and angle options in my garage it was time to call our friends at CSF for yet another cooling solution. It didn’t take long to get them on board, and just a few days later I was making the drive up to the CSF headquarters to have my freshly KONG ported 1.7L blower 3D scanned, so they could carry my design intent the rest of the way… and boy did they!
After two months or so, we had a full size 3D printed mock up that was just about ready for functional prototyping utilizing their recent investment in intercooler core manufacturing. Luckily CSF saw the value in helping us bring this to market, so with their extensive industry resources and experience, it was not long before we had the first functional model that was ready for bench testing.
Although we still have two more sets of prototype bricks out for additional validation testing, early results verified improvement in several vehicles and driving conditions. Preliminary street / DYNO testing showed MAT reductions of 5-20F at different points of a 45min test loop with multiple 60-130 pulls in 85-90F ambient temps. Additional DYNO testing showed not only IAT reductions increase pull and after pull but a subsequent increase in HP also. Although we are not advertising these as HP generating bricks, having a cooler intake charge (even 5 degree’s cooler) can prevent timing from being pulled if you were just over the threshhold, which can keep timing and HP in place when you need it most! As always, your results will vary.
These results are not surprising considering that these new CSF Bar & Plate Intercooler Bricks are now 50% taller than the OEM units, and hold nearly 70% more fluid! These 1.7L Supercharger Intercooler bricks also allowed the HX Coolant to flow 12.5% more GPM over the OEM units on our 1,000hp SHOP CAR that is currently running our Stage.III Super Charger Cooling System. All facts that will help them pull more heat out if the intake charge, providing you more cooling headway to keep those dreaded manifold air temps at bay, in order to delay or prevent timing from being pulled when it matters most.
Key Benefits:
Nearly 70% more volume + 12.5% more flow + 50% taller than OEM LT4 bricks.
No custom orders needed. These will be in stock and ready to ship soon.
Each unit is pressure and O-ring seal tested in a factory 1.7L blower.
Each set is treated to a durable CeraKote Thermal Coating.
Durable bar and plate design aids heat transfer and flow.
Billet End Tanks are CNC milled for precision fit.
Includes front and rear air deflector brackets.
Comes with a CSF 2-year limited warranty.
Each pair comes with new O-rings.
No loss in CFM airflow.
Why the bricks matter so much:
Simply put, the LT4 supercharger intercooler bricks are solely responsible for pulling heat out of the intake charge, into the HX coolant, for the rest of the front mount heat exchangers to exchange the heat once again, in order to provide as low of a coolant temp as possible, to enter back into the bricks in order to do it all again. That is why the bricks have always been the weak link of the system.
Understanding that O-ring seal leaks, and lack of 3rd party results have been issues plaguing other brands attempting to bring similar solutions to market, CSF went to great lengths to ensure a proper fit, and proven results before they would release to production. CSF even went as far to purchase a 1.7L blower to send to the factory so each new intercooler brick could be pressure and seal tested, in the intended location using pressurized helium gas (which has 36% smaller molicules than water) in order to ensure a tight fit, every time.
Tube & Fin vs. Bar & Plate
Both tube-and-fin and bar-and-plate intercooler bricks cool the intake charge through convection into the fins, conduction through the aluminum, and convection into the circulating coolant. With similar aluminum alloys, additional thermally active metal mass can absorb more energy for the same temperature rise. Bar-and-plate cores typically provide more of this thermal buffering, helping limit temperature increases during short pulls, while lighter tube-and-fin cores store less energy and have less stored heat to release during recovery. Recovery speed, however, also depends on how effectively each core transfers heat. As pulls repeat with limited cooldown, heat-transfer surface area, fin efficiency, flow distribution, and coolant inlet temperature become increasingly important. Greater thermal mass can delay warming, but maintaining low intake temperatures requires the coolant circuit and external heat exchangers to continuously carry that energy away. For the new CSF bricks, nearly 70% greater internal coolant volume adds thermal storage, while the 12.5% increase in cooling-circuit flow measured on our development car increases the coolant’s heat-capacity rate. Together, these changes provide an engineering basis to expect better consistency over closely spaced pulls, provided the core transfers heat effectively and the external heat exchangers keep coolant temperatures controlled. That expectation comes from the complete design; the bar-and-plate construction alone does not establish repeat-pull superiority. This is why we have always said there is unfortunately NO silver bullet for cooling mods. An effective system needs add both increased capacity, flow and heat transfer surface area in order to ultimately help your cause!
Bundle Options: In an effort to keep you cool, we are offering FREE SHIPPING on all bundle options shown. Items may ship direct from the manufacturer.
Installation Notes: Although we recommend that all supercharger intercooler bricks are professionally installed, DIY installation is possible, so long you are able to pressure test the bricks o-rings prior to filling with coolant. This is critical as we have seen the bottom O-ring roll out and create an air leak on more than one occasion. Which is why O-ring lubrication and pressure testing is so critical. As expected, CSF can only warranty their bricks from manufacturing issues. Issues caused during or after installation are not the responsibility of GMS / CSF. Please take your time, and follow GM service manual procedures to prevent leaks and engine failure.
Intended Fitment: All OEM 1.7L Eaton blowers found on all 2017+ Camaro ZL1 / 2016+ CTS.V / 2022+ CT5-V Blackwings / 2015+ Z06. Note; that GEN.1 blowers do require flange modifications if being used. Note; that the tall OEM lid or equivalent is required for fitment. The product will NOT fit aftermarket lids that are shorter then the OEM tall lid. The tallest point of the CSF brick, with bracket fastener is approximately, 1.3” above the lid flange. We have confirmed fitment with the DMS Lid, OEM Lid, MPI Lid, and Too High PSI Lid only. Although we do not expect issues with any other aftermarket lid, so long they offer a minimum of 1.3” internal clearance.
