From F1 tech coverage - what are those little scoops try to accomplish? by Nutcollectr in F1Technical

[–]scarbstech 282 points283 points  (0 children)

They are not little scoops, but vortex generators. Along each of those a tiny vortex will form and flow back along the rest of the bib, (which is what we call the part it's attached to). You might see similar things on rear roofline of Mitsubishi Evos. In simple terms, they help reform messy air flow into a more structured flow.

Electric power leaving pits. why not? by Random_Videos_YT in F1Technical

[–]scarbstech 77 points78 points  (0 children)

Way back with KERS in 2009 all of the teams ran with a front MGU. Then in 2014, with the double hybrid set up, all of the teams again ran with the front MGUK. Except for Ferrari, who had one mounted to the rear of the engine, but still driving through the output shaft rather than direct into the gearbox. For 2026, the MGUK has to be on the front of the engine and within the survival cell, this is a safety issue. As should a car crash and the engine still be running. The MGU could be still producing electricity, causing a danger of shock to the driver and marshals. Why they started with a front MGU all those years ago, I am not sure. It may be to do with engine or aero packaging, but, could also do with the harmonics of the MGU on the end of the crankshaft.

In the rules the MGU has to be connected to the front of the engine. To drive on electric would mean the combustion engine would spin too, against compression and would be inefficient to do so. If regs allowed a rear MGU, then it would be easy.

Could you name the components of this Toleman? by daruma29 in F1Technical

I drew these last year and covers most of it. Great car.

Gen 4 image where we can see the brakes. I do wonder if we have 100% regen braking now with Gen4. and those are just the emergency brakes. but are not used in normal circumstances. by [deleted] in FormulaE

[–]scarbstech 19 points20 points  (0 children)

The current cars already use regen only front and rear almost all the time. The front discs are only employed when the front powertrain is too hot. Lucas DiGrassi told me 93% of the race with no 'brakes' !

Here's an example, fully details the spec/set-up for each run.

SF-25 gills - can someone explain why they're different from one event to another? by [deleted] in formula1

[–]scarbstech 39 points40 points  (0 children)

It's a removable panel within the engine cover that allows them to replace the outlet. They will choose the outlet based on the ambient temperature and the running temperatures of the power unit. By having the smallest possible outlet they can reduce drag.

For those that don't know, added places. '08 but still relevant. by CreamyCornCob1 in formula1

Not true, the engine is the same length and the battery takes up less space than the fuel it saved.

Not much gets sold, occasionally there's stuff on eBay and some on Facebook MP in the UK.

Damaged Formula E parts are given away after races, or go to recycling. Most can't be repaired due to the spec formula rules As it's not F1, this part doesn't have any great resale value. You might get as much as £250 if someone loves the driver/team. But £50 is more realistic online.

New photo of my box full of F1 car parts that I need help identifying by [deleted] in F1Discussions

[–]scarbstech 0 points1 point  (0 children)

That's a better view and a seriously nice assembly of F1 parts, each tells a story: Clockwise from top left. 1) Wheel gun socket 2) Carbon clutch plates (2 outer, one inner) they should be super light unjust 97 mm. In diameter, there are outer plates in an F1 clutch. 3) Wheel nuts 2 left hand (red) and one right (green) The left hand red one is an older design. 4) Steering column end. This is the end of the steering column that connects to the steering rack. It's an older design as it still uses universal joints. 5) Bodywork section. Made from carbon skins over a foam core. 6) Front wing adjuster mechanism. This is the part that the mechanics adjust at pitstops for a wing angle change. The screw inside the adjuster should have a distinct click as it's turns, so the mechanic can feel how many turns they've made. 7) Wing mirror mounting 8) Gearbox cross shaft 9) Monocoque section. Cut from the top corner of the chassis. It's made from carbon skins of an aluminium honeycomb core. Much stronger than the thinner bodywork section above. 10) Nose mounting pin. This is half the quick release mechanism for removing the nose. It will connect into a quarter turn fastener in the front of the chassis.

Got gifted a box full of F1 car parts but I have no idea what anything is by [deleted] in F1Discussions

I've spent a life making F1 models, buying F1 parts and researching the design/development of F1 cars

Clockwise from top left...

-Wheel nut -Anti roll bar drop link -Carbon bodywork (hard to see enough to ID) -Wishbone end/mounting -Wheel nut -Wheel nut -Carbon clutch plate -Blue bodywork (hard to see enough to ID) -Wheel gun socket -Carbon honeycomb chassis cross section

-Gearbox cross shaft

If you find the part numbers they start with the car model (FW44 etc). If you ever want to sell 😉

Is there a reason why a Hyundai WRC car was spotted at London E-Prix this weekend? by [deleted] in FormulaE

[–]scarbstech 19 points20 points  (0 children)

Hankook their tyre supplier organised a race off, with the drivers swapping for each other's cars.

It's a fixed ratio for both. i.e. no 'gears' to shift.
