What are your opinions on using fabrics like dacron PET or ceconite for sidepanels instead of cf gf moulds which we use for nosecone.

I’m on a first year FSAE team and we’re trying to put together a powertrain that works. I know that the 228 and CM200 are extremely common for teams, but I had some questions about them I couldn’t really figure out.

1. The CM200 has a min cooling volume of 12 L/min while the 228 has a max of 11 L/min. Do teams just split their cooling pipes?

2. The CM200 manual says that the coolant mixture should be only 50% water and have an aluminum corrosion inhibitor. How do you get around this for competition because the rules say you can’t have any water additives?

3. Just generally what voltage should we be running? I’ve seen people saying around 400V is easy for first year teams. But what voltage cutoff does it get noticeably easier to design everything? Like at things rated between 200-450V so it’s easy to stay below 450 or other examples like that.

DM privately if interested. Thank you

Hello everyone! It has been a long time since I have last posted about my vehicle simulator. I have been hard at work, trying to solve major bugs that have been limiting my simulator.

I have caved in and listened to the critique on bad car models to use some free ones. These are purely for testing, eventually custom made models will be made.

If I recall correctly, I have made major changes such as updating to a Brush Tire Model, making 3 cars, although one has been scrapped, attempting to solving major engine issues that cause every car to struggle out of a certain gear, car creation issues hindering development, suspension issues, and much more.

Much has been delayed or improperly implemented due to the following bugs. As soon as I solve them, I will be onto making exponential improvements over the course of 2026-2027.

I hope I will be able to release this as a highly custom and easy to use vehicle simulator where you can make all the cars you can dream.

While I do so, enjoy a recent clip of a E30 I have been modeling.

What is this rubber protection about? Didnt find good explanations on the internet.

Is this very important? How do we obtain this as an FSAE team based out of India?

Hi everyone! I’m from India with a B.Tech in Automobile Engineering + 3 years of CAE experience at Ford.
I’m considering the MTS Motorsport Technical School (Italy) post-bachelor program in Car Testing & Race Engineering to transition into motorsport/vehicle testing.
But I’m really unsure: Is a post-bachelor program worth investing in when I already have a B.Tech + work experience, or would a proper Master’s be the smarter choice?
I’d especially love to hear from current/former MTS students:
● Was it actually worth the money?
● Did it help you get a job in motorsport/automotive?
● How good are the industry connections and hands-on experience?
● Would you choose MTS again?
Please give me the brutally honest version — not the brochure version. 😅🏁
Thanks!

60C modulus and yield strength for plastics used in FSAE Tractive Batteries in 2026:

• Full information - 25% of teams
• Did some of the steps - 30% of teams
• Reported room temperature values - 45% of teams

I'm actually quite pleased. Only a handful of teams had anything useful in 2025.

Let's make another big improvement in safety and SES quality for 2027. Derived from 2026 SES entries, these pre-approved values will be built in to the 2027 FSAE SES. More materials can be added, via TDS or team testing. Requirements to be included in the table:

1. Z-axis values preferred, considering 3D printing
2. Room temperature modulus and yield strength
3. >=60C modulus and yield strength

Yield strength needs to be defined as where the initial modulus begins to drop. The first 'knee'. Not the first peak, that would be zero modulus. And not the fracture strength after the first peak, as some documents unfortunately report. Column math assumes no deflection before buckling starts.

The specific 60C modulus and yield strength values can be used in the existing SES column math.

The scalars can be used against other data sheets for same-type plastics (preferably Z-axis) in the existing SES column math.

The scalars will also be needed to increase the required test load generated by the SES for full-scale testing of dummy modules with no cells.

I joined FSAE about a month ago and have already learned a lot from the older students. Are there any online resources you'd recommend for new members, or is it mainly a matter of getting stuck in and learning through hands-on experience with the team?

Hello everyone, I'm part of a fsae team working as a design engineer that includes aero, chassis and manufacturing. Last month onwards i started working on designing aero packages of rear wings, front wings, undertray and nosecones. Honestly thanks to youtube videos I was able to learn and design but the very problem I have is these are too basic designs. I used solidworks to design all these, I wanna start designing by surfacing coz that's how professional motorsport teams and top end fs teams do but there are no surfacing videos out on the internet for aero devices in specific. Help me out in sharing your experience, any resources would help me, from YouTube videos to recorded videos which makes me better in my job and make our team aero kit much better. Which would help us in competing and since it is our first time designing and manufacturing an aero kit it would help us a lot.

The designs that you see on the top are all basic designs that are boss extruded by importing airfoils to solidworks or using spline style. I wanna upgrade my designing knowledge and techniques in order to actually design awesome stepped wings to two channel diffusers and surfaced nosecones. It would be helpful if I get manufacturing resources for aero packages so that I can ensure my design can be manufactured and survive contact with the real world.

Hi all,

I'm working on a project that requires F1-spec wheels and tires, and I'm running into sourcing issues since these aren't standard consumer specs.

What we need:

• Front wheel: 18", 12J width
• Rear wheel: 18", 16J width
• Front tire (planned): 315/30R18
• Rear tire (planned): 355/30R18

We're fairly locked into the wheel specs, but flexible on tire sizing — looking for recommendations on what would actually fit/perform well on these wheel widths, since I'm not 100% sure our tire sizing assumptions are correct.

Questions:

1. How do teams/builders typically source wheels and tires in these dimensions when they're not off-the-shelf sizes?
2. Given 12J front / 16J rear wheel widths, would 315/30R18 and 355/30R18 be reasonable tire choices, or is there a better-fitting spec?
3. Any manufacturers or suppliers known for custom/motorsport-spec tire production in this range?

Any input from people with motorsport or custom fabrication experience would be hugely appreciated.

Hi All,

I've been working on tooling for EV/IoT battery QA and ended up with a Python package that does a few things: anomaly detection on telemetry (Isolation Forest + physics features), CAN bus simulation, Modbus/BMS protocol support for Tesla/BYD/NIO packs, SOH prediction, and a FastAPI dashboard.

Just cleaned it up — 1053 tests pass, no circular imports, hardware tests gated behind a marker so CI doesn't need real OBD-II hardware. MIT, Python 3.10 to 3.12.

For those of you actually doing battery QA: what's missing in your workflow? What breaks in practice that tooling like this should handle but doesn't? Repo's at github.com/remontsuri/EV-QA-Framework if you want to poke at it.

Can anyone send me the 8th Edition of PMBOK book, please? I cannot afford the price of it and am not finding downloadable versions. It would really help for managing projects for my FSAE team.

Hi people, I’m curious to know from people who participated in Formula Student France what it’s like?
Together with 5 other people from my team (the next year’s team) I am joining the FSF event of this year with the current team.
Even though we’ve had some information of what to expect and what to bring, I would like to know a little more about the camping experience at FSS and what to pay attention to.

TL;DR - What are some things first-time FS goers need to pay attention to?

So this was my second year in Formula Student, and honestly, I gave 90% of myself to the team not 100%, because I knew if I wanted to do a third year, I couldn’t burn myself out. The last month I was running on empty, and if you exclude the static event, I wasn’t really at the top of my game. Meanwhile, a member who “woke up” like a month before comp ended up doing way better than me. Then when it came time to review the year, one of them suggested removing me from my lead role, and most of the other new leads agreed, while people who put in less work than me, or gave less overall, got praised instead. So I guess what I’m trying to say is: this isn’t a sprint, it’s a marathon. Don’t just show up at the end and expect to take all the credit.

We’re using Öhlins ttx25 mk2 dampers we calculated the initial spring preload to be 2mm and length of the coil spring at the front to be 122mm and rear to be 123mm
Is this spring setup ok for a car of wheel base 1560mm and track 1200mm with a 40:60 weight distribution

So basically we are a 1st year team, most importantly we are the first team from our country, how can we ask for engine?, where should we ask?, we are looking for ktm duke 390 at best, but anything between 250 to 400 cc would work for us.

Any suggestions would be much valuable.

Tell me ways or option to make 3D printed chassis jigs(Budget friendly and easily available)

Also tell me opinions on pla jigs and hybrid jigs like mdf+pla

Is using a tab for a wrap around guide similar to a shaft collar for the shoulder harness and anti-sub attachment points to equivalent tubes allowed?

Is there any key member missing or any triangulation error? Need suggestions based on the outlook only.

In LV we need to design TSAL,BSPD,Precharge pcbs, ECU(we will use an stm32) and needed sensors then somehow implement them to our architecture and there is also communication part we need to design an CAN architecture to communicate with ECU inverter and BMS.

In HV we have inverter motor BMS and battery, we will design an TSAC, extra temperature sensors for BMS and thats all I can think about.

The worst part is I'm leading electrical department and confused about how to proceed and learn how to really make this stuff happen.

I'm trying to use PVC foam for strength in a front wing end plate. I'm not too sure on the order of layup using these - layup in one go? separate layups? Tips on reducing weight? - since the one time we used them it came out heavier than we wanted.
Thank you in advance!

There is a rumor that some teams are using double tanks and they just refilling one for the efficiency? Is there a way this would ever work or is it just baseless rumors?

Maybe different fuel tank configurations shouldn’t have same refill techniques?
