FATech Thursday: The Damper System 🏎️
The damper system controls how the car behaves over bumps and in corners, keeping it stable and predictable for the driver.
On the FT25, we use the KW V5 Evo Formula Student dampers, paired with our self-built rocker arms.
Small components, big impact: a well-tuned damper system makes the car faster, safer, and easier to drive. ⚡

FIEver wonder what actually happens inside a torque converter after a pass? 🔧🔥
The beauty of a bolt-together converter is simple… we can tear it down, inspect the lockup clutch, check the turbine and pump health, and know we’re ready for the next round. 💪
When you see RPM drop slowly instead of sharply on shifts, it’s a sign the lockup might be slipping… so we crack it open, verify the clutch health, and get dialed in before qualifying.
This is how you race smart. Inspect, adjust, repeat. 🏁
Got questions about converter health or shift behavior?

EN“Just sniff the oil.” 👃⛽️
You spend thousands on machine work, the perfect ring set, and hours of assembly—only to wash the cylinders and kill the rings before the first oil change.
Keith Jones from @total.seal shares a wild story about a "mystery" engine failure that was solved by a Pepsi bottle and a quick sniff test. The culprit? A "dyno carb" that masked a massive tuning issue waiting at home.
Don’t let a “safe” fat tune-up turn into a solvent that destroys your cylinder walls.

COIf you’re looking to take your bracket racing to the next level, a transmission temperature sensor is a must. When you truly understand your car and how it reacts at different transmission temperatures—whether it’s cooler or hotter than normal—you can use that information to your advantage and adjust your dial accordingly.
By adding a trans temp sensor to your Pro Dash, you can set clear blue, green, and red zones so you instantly know if the temperature is where it needs to be. With just a quick glance, you’ll know if everything is in the sweet spot, and over time you’ll develop the knowledge to make smarter dial-in adjustments when it isn’t.
This is how you take bracket racing to the next level.
Tune by data, not ET slips. 🏁

GLHow It Actually Works Turbo lag happens because exhaust gas energy at low RPM is not enough to spin the turbine fast. A NOS ejector solves this by using nitrous oxide to artificially increase exhaust energy for a short duration. When nitrous oxide is injected near the exhaust manifold or turbine inlet, the high temperature causes it to decompose into nitrogen and oxygen. This reaction increases exhaust mass flow and creates rapid gas expansion. The ejector nozzle converts this expansion into very high exhaust gas velocity, creating a low-pressure zone that pulls more exhaust gases towards the turbine. This jet-pump or ejector effect helps the turbine wheel accelerate much faster. The result is instant turbo spool-up, reduced turbo lag, and quicker boost generation, especially useful during launches and low-RPM acceleration in high-boost setups. Once sufficient boost is achieved, the NOS system is switched off to avoid excessive thermal stress on the turbocharger. This system is mainly used in drag racing and performance applications where fast boost response is more important than long-term thermal efficiency. #Turbocharger #NOSejector #NitrousOxide #TurboLag #BoostedEngine ForcedInduction TurboSpool DragRacingTech PerformanceEngineering AutomotiveEngineering ExhaustEnergy HighBoost MotorsportTech EngineDynamics AutoXec

ENStressing out over your LS block? 🛠️
Ever wonder if you should be vibrating your blocks to relieve stress before the final bore? Joe Creason and Tim Eichhorn weigh in on their process for aluminum blocks and whether frequency tuning actually matters in the real world.
This episode was one of our most active EVER—we covered everything from "crush" specs to the "Step-Down" method. If you’re serious about the "Art of Sleeving," this is your masterclass.

COAs air compressors and starting line enhancers become more common, knowing your air pressure before you stage is extremely important. The worst-case scenario is going to activate the starting line enhancer and having nothing happen. By adding an air psi gauge to your launch screen, you can set a warning light that alerts you before the run if pressure is getting too low.
We also like to use the sensor to help control when the air compressor cycles. You don’t want the compressor kicking on during the launch or while going down track, because it can rob valuable battery voltage that your ignition and electronics rely on for power and consistency. If you notice the pressure starting to get low, simply cycle the starting line enhancer a couple of times to use some air and trigger the compressor before you make the pass.
Control your variables, and you put yourself in control of the race.

SIPrecision fabrication isn't just about making parts fit—it's about flow and building strength where it counts. Every bend, weld, and joint affects how your race car performs on track.
Don't settle for sloppy fits that kill power and durability. When you demand precision, you get a machine built to win.
Tag your racing buddy who knows the difference between a quick fix and a pro build!
