Stage3 doing 3.68 200-250. Integrated high flow turbokit. Development and racing.
Hello to all forum visitors and performance enthusiasts!
This is my first post here but i hope it will be pretty interesting for the community.
As a racing team and engineering company we purchased the Turbo S in 2020.
We were not the first to get the car but had 3 warm month to work on ECU tune and light mods - downpipes only, OEM non-sport exhaust.
Best ET as for 2020 was 9.577@231 km/h (144.4 mph) and best trap speed was 235 km/h (146 mph) in the 9.586 run.
Spec: 20" MT S/S, catless pipes, ECU tune, BMC air filters. 992 Turbo S on a drag strip
Posting here to share the ideas, process and results of our 992 platform development process.
While it was cold winter outside - we disassembled and scanned the car, worked on the design of a complete turbo package.
At the moment we have made several units and now testing manifold.
The intake manifold is quite similar to 991 product we proudly produce for By Design https://rennlist.com/forums/members/...-bydesign.html.
The design efficiency is proven by several powerful 991s with ByDesignXR turbo kits and we implemented the development method to 992 intake manifold too.
Complete solution overall idea is a FLOW - get the lowest pressure drop on every step and every corner, reducing backpressure and avoiding excessive engine load.
More power with less stress on engine components seems like a great goal for us.
Manifold provides great torque gain above 4000 rpm (working now on the dyno numbers to be exact) and the I/C provides true improved flow as well as core volume.
82 mm TB is a default for the manifold, OEM fits via adapter
I/C specs: - Complete one-piece design to ensure best flow rate possible. No bottleneck transitions or unnecessary flange connections. No air traps on the flow path. - CFD optimized end tanks design to reduce pressure drop. - Core volume increased by 31% compared to OEM. - Increased transection of a whole unit to create perfect flow. - Direct fit air ducts to suit bigger core. - Air ducts equipped with water spray ports for future upgrades. - Pre-TB watermethanol threaded ports. - Removable bypass valve flanges for future upgrades. - Pre-TB threaded pressure sensor port. - Lightweight 5-axis CNC machining design of parts. - Designed to suit OEM and LEVEL TORQUE MONSTER intake manifolds. - Bolt-on fitment, NO modifications to car is needed. - Different core types for specific applications be available.

We are now limit by OEM clutch capacity even on high revs, so OEM turbos are not maxed out yet.
Need to add some PSIs on the clutch and go further. Then grow the capacity and go one more step.
More products are coming.
Welcome with any questions and comments!

Reason: renamed the topic
You using CSF intercooler cores, or your own? Nice stuff, my 991.2 was done by Sam in 2018, my 992 tts will be in Cali in Sept. needs to be made fast. Really nice products you guys make.
That's stuffing a lot into the back of the car. Gonna be a serious piece of hardware.

These ones are BELL intercoolers bar and plate, we used them in several air-to-air and air-to-water setups with fully proven efficiency.
Current setup balance is in thicker core and bar/plate design. 992s seem very similar to 991 but new era has come for sure - all components are next gen. Oem core is a really nice one, much better then 991 had. So It is difficult to achieve a real improvement there.
We are working on the 4.5 and 5" core unit design with custom spec rolled tube cores too - for time attack and endurance applications as each core type has pros and contras.
Wait, did I read that right? Clutch capacity is maxed before stock Turbos?
How much HP/TQ you putting down at this stage?
Beautiful Work!!
We are going solid 9.57-9.58 with 730awhp/905 N*m (dynojet reading, DIN). It is a really solid and safe spec, reliable at -30..+40 celsius. Torque is limited for safety and moreover - the peak is doing nothing during launch starts, all the race revs are above 4200 rpm.
As we experienced during testing - clutch protection activates at ~950 N*m (on dyno) and as reported by partners clutch is actually slipping at 970 on a stock! intake manifold and exhaust at 2900-3100.
We experienced slipping above 970 N*m in a 5000-6000 rpm zone with our new manifold. So need in clutch pressure raise procedure FTW. It will allow us to go higher.
simultaneous work of variable geometry and electronic wastegates is awesome for stock but pretty complicated to control. Torque peak at 3000 rpm is an issue. It should be significantly limited.
We spent lots of runs to keep torque curve linear.
There is a user-friendly dyno result image to compare hp and torque in different rev points. Pick a point and you'll get readings and gain.
What fuel specs on the 9.5 at 146mph passes. Well done ! Awesome power. Any Dragy pics ?
Vp Racing MS109 for all the runs. And to be precise (my first message will be updated) the trap speed at 9.577 run was 231 km/h (144 mph), 235 km/h (146 mph) was a trap speed of the 9.586 run.
Sorry for the misleading translationin first message.
No dragy for the best run but attached the screenshot from the live video.
Btw, how do you find the 1.425-1.440 60ft time comparing to US strips? We cant get lower yet.
