Cooled Operating: Pushing The Porsche 992’s Limits With CSF & Autowerks
It’s straightforward to take without any consideration simply how a lot improvement goes into ‘correct’ modification.
However that’s additionally a testomony to doing a job correctly. As a tuner, you’re supposed to do the onerous work so the fortunate buyer can reap the advantages after. And within the case of Porsche 992 tuning, meaning further energy. Tons of additional energy.
Once I visited Bangkok just lately, I had the pleasure of spending a while with Warren Adulayavichitr and the group at Autowerks Asia to get a really feel for a way they function and what they do. As certainly one of Thailand’s greatest tuners, they’re chargeable for a few of the wildest builds proper now.
And meaning frequently looking for out the tech and merchandise which elevate their tuning to the subsequent stage, such because the just lately developed CSF intercooler improve for the Porsche 992 Carrera platform.
The automobile pictured right here is way from inventory already; it’s primarily modified to a ‘Stage 2’ stage, which consists of an Akrapovič Evolution titanium exhaust and hyperlink pipe, IPD consumption plenum and BMC air filters (in addition to the all-important software program). The means an influence hike all the best way to 550hp and 700Nm, which is greater than wholesome for an in any other case ‘base’ 992 Carrera.
However energy isn’t the one focus right here. AP Racing discs and features deal with the additional stopping energy required, and HRE R101 solid wheels beef up the outside to match its efficiency. However what about if you wish to push the tuning envelope even additional; what occurs then?
Ever since Porsche made the soar to a 3.0-liter turbo engine, it has (inevitably) introduced a whole lot of potential into the aftermarket tuning scene. With primary mods 550hp is a wholesome end result, however swap out for larger turbos and also you’ll quickly be knocking on 700hp. Or as Warren from Autowerks helpfully explains, the “GT3 killer” package deal.
Fashionable engines are extremely environment friendly, so the second you start pushing them into severe energy ranges the necessity for cooling will increase exponentially. And that’s not only for the large horsepower builds; the identical goes for these wanting a extra track-focused construct too.
So, what you’re taking a look at right here is likely one of the first intercooler upgrades for the 992 Carrera, constructed and developed by CSF Radiators. With a little bit assist from Autowerks, it’s additionally the primary 992 in Thailand to be fitted with this equipment.
Naturally, Warren and the Autowerks group have been tremendous eager to see what advantages could possibly be gained from the CSF improve. Time to get the intercooler fitted and reveal some correct numbers…
For this specific check, Warren strapped the automobile to the dyno in an effort to achieve a base end result. Autowerks use a SuperFlow Dynamometer, an extremely subtle chassis dyno that ensures correct information is gathered in real-time for exact tuning. After placing the 992 via a number of runs, the general room temperature was taken to be 28°C (82°F), which is value noting for after we see the ‘after’ figures.
I’m at all times amazed by simply how tightly packaged trendy Porsches are. It’s a testomony to Porsche’s engineering division, however a headache in the case of attempting to extrapolate extra cooling efficiency, as there merely isn’t the house to suit the most important cooler doable. We’re not within the ’90s anymore…
However fortunately, Ravi and the CSF group thrive on these type of challenges. By improved core expertise and packaging, they’re capable of significantly enhance the stream and general space.
You possibly can see that right here with the inventory versus CSF items positioned side-by-side. Discover how the CSF unit manages to make the most of extra of the realm across the edges to maximise cooling. That additionally means the all-important manufacturing facility ducting may be retained, in addition to the intercooler using all the inventory mounting factors to end in a brilliant slick set up.
CSF even embody becoming directions with each equipment to make set up as easy and simple as doable. Simply look how neat the intercooler seems to be as soon as bolted in place – you’d be fooled for pondering it was an OEM merchandise! However seems to be are nothing except it’s enhancing efficiency. Time to go again to the dyno…
Thailand is a scorching nation, and by this level within the day the air temperature inside Autowerks’ dyno room had risen to 33°C (91°F). Followers on to maintain the check as truthful as doable, the most effective we will do it deliver the temperature all the way down to 29°C (84°F) – not ultimate, however not too far off from our base stage.
With the 992 going via a number of runs, it was instantly clear that – regardless of the hotter ambient temperature – the automobile was already operating a lot cooler, even via the mid and excessive rev vary.
The outcomes fairly actually communicate for themselves. Energy is up all through the entire rev vary, with the most important beneficial properties coming in between 3,500rpm and 4,000rpm – an extra 32hp and 50Nm of torque simply from the intercooler improve. However honestly, the most important good thing about this CSF improve isn’t simply the ability enhance – it’s the power to keep up constant energy (and temperatures) run after run.
“From our personal testing on the 992 Turbo and RS6 coolers – which use comparable core specs – the most important delta between CSF and OEM is that the efficiency from the OEM coolers deteriorates rapidly after a number of dyno runs,” Ravi at CSF explains. “Evaluate that to the CSF coolers they usually stayed constant from the primary run proper via to the fifth. That is particularly helpful for monitor vehicles, drag vehicles and even quick highway vehicles. There’s no energy loss due to warmth soak.”
Whereas it’ll come as no shock that an uprated intercooler will increase energy, it’s superior to see that – even with vehicles as environment friendly and tightly packaged because the 992 Carrera – producers like CSF are nonetheless capable of push the boundaries leaving the door vast open for tuners like Autowerks to proceed improvement.
We frequently look again at eras of tuning with rose-tinted specs, and when you might argue a 992 Porsche doesn’t actually need anymore energy, if we’d all adopted that angle there wouldn’t be a tuning business to take pleasure in. So we salute CSF and Autowerks; if our time with ICE engines are restricted, we might as effectively take pleasure in them to their absolute restrict.
Because of Warren at Autowerks and Ravi at CSF for serving to coordinate this shoot. Keep tuned for extra from Bangkok!
