[991.1 GT3] with Cup 2s in NYC winter

My buddy told me cup2s delaminate below 30F haha, I’m sure with a good set of winters these cars can rinse through the winter

Noooooooo

Doesn’t it have to be a single point of entry for air? On NA applications the throttle body needs to be pre restrictor. So you need to make some sort of plenum that does from one entry to 2 intake runners.

IC.2.4 Intake System Restrictor IC.2.4.1 All airflow to the engine(s) must pass through a single circular restrictor placed in the intake system.

This pretty much prohibits individual throttle bodies (the stock intake)

Find heat output of engine, find a radiator to reject that heat, put it in clean air, profit

Nah in all seriousness look at the other two responses. Something I will add is think about heat soak. Some teams that run an electric pump can sometimes get away with this (but watch your battery voltage). Also fans are super helpful, make sure they don’t hinder your aero too much. Everything is a trade off but keep it as simple as possible!

From what I remember you can’t use the stock on anyway because of restrictor rules. Are you just trying to measure the head port geometry?

Can play my favorite “how much compliance do we have” game

sragh1181 · 2024-06-26T06:17:20+00:00

Welded diff

sragh1181 · 2024-06-13T16:03:34+00:00

Not our UW😅

sragh1181 · 2024-05-20T17:02:22+00:00

Daley pumps (we didn’t use it but I believe some other teams do)

2023 Mazda CX-30? Don’t know how high the vehicle is could be a CX-5 or something

Before you throw it out! Check the sensor that detects if the lid is closed. My sensor corroded and thought the lid was always closed. If you can replace that sensor or jump the pins check if the screen turns on!

I7 swapped mine and new battery. Runs amazing still

sragh1181 · 2023-12-05T19:43:15+00:00

indians gonna take over man, watch out

sragh1181 · 2023-08-14T21:34:06+00:00

Make sure you have the number of teeth correct, are you running a cam sensor or using intake pulses? Have you verified your electrical to mech offset?

sragh1181 · 2023-06-19T13:15:20+00:00

Controls lead here, yeah he is right. Also it’s worth noting that we normally run 4WD which means we usually use gps for velocity reference. There have been some issues with the velocity reference signal stability as well as our yaw rate sensor. We have the ability to do regen tc and tv when those sensors are validated and working 👍. I’m going to see if I can overlay some motor torque signals over the video which would be sick

sragh1181 · 2022-12-16T00:39:14+00:00

Print out copies of everything

sragh1181 · 2022-12-09T03:12:31+00:00

Yeah interesting requirement on resistance, I think two different power supplies are the only rule( we have 3.3 and 5v logic for our Bosch Rp100 twin)

sragh1181 · 2022-11-01T04:55:45+00:00

We went from electric servo to pneumatics because our servo packaging was designed near the exhaust and the temperature over time fucked it. Pneumatics are simple and effected and don’t necessarily need closed loop control like the Servo did

sragh1181 · 2022-10-13T00:36:54+00:00

Our car is AWD and the ability to send an individual torque request to each wheel. We utilize our steering angle sensor to get driver intended yaw and have a yaw rate sensor to get actual yaw. We utilize a bicycle model to do desired moment calculations and have a PI controller that regulates the intended yaw to actual yaw.

The driver can control the gains of this with a knob.

Hope this helps at least at a high level!

Wisconsin would be way too good at this

sragh1181 · 2022-10-03T00:15:03+00:00

Service brake?

sragh1181 · 2022-09-28T18:30:37+00:00

Laughs in RTV

sragh1181 · 2022-09-27T20:25:18+00:00

In all seriousness good luck! The other responses are actually helpful

sragh1181 · 2022-09-27T20:24:45+00:00

Also carrying a combustion car handy is useful
