Wheel speed sensors

[TopTuning]

Hello all!

Just test fitted my new rear wheel speed sensor rings:





2 Part 60 tooth sensor ring for almost any 108mm CV joint. Clear signal for wheel speed, ABS systems etc.

Direct fit for Porsche 911/930 with 108mm CV joints. May fit other brand 108mm OD cv joints with 94mm bolt circle. Interlocking parts for a perfect fit and no disassembly required. Just fits under axle bolts!

Parts are magnetic steel and gold zinc plated to work with hall or VR sensors.

I made a LOT of extras so,

These are now available here:
https://www.ebay.com/itm/375521020952

Pelican parts member price is 35 for one axle or 60 for pair.



I'm now working on the much more difficult front wheel speed sensors. Would love to see what anyone has developed.

Sorry for the stupid.question, but what reason is there for speed sensors for a car made without sensors.
Nannys?

Traction control. Aftermarket ECM can use this input to close the electronic throttle and limit power output so you don't roast the rear tires when accelerating in traction-limited environments.
TOP has a throttle by wire ITB boosted, water-to-air intercooler setup on his car so his needs differ from others.

Traction control, cruise control, launch control, gear or speed based boost control, aftermarket ABS...

Very cool!

What are you doing for the front? I have output flanges for my gearbox with teeth...what I need is a good solution for the front wheel speed sensors on G-body front hubs....

As I thought , nannys ,
I am old school , I think nannys are for people that do not want to learn to drive or just can't drive.
So if you have an old school 911 why in gods name would anyone install nannys .
So I think it is more important to learn how to drive what you are driving , than adding nannys .
I am very aware of the benefit of cruise control , that might be a reason for the install .

I guess i am just surprised that a real 911 would get a nanny installed , or do that to a Lotus Elan or a Daytona coupe cobra, or a Ferrari GTO, how Bout Vick Elfords 911R
Learn to love the Magic !!!!

Or buy a Tesla .

I am interested because the MoTec M1 series traction control is a speed enhancement tool is worth some time on the race track. Both in the ability to come out of the corners harder and in reducing the chances of over heating the rear tires due to spinning the tires too much.

Bosch Motorsport ABS is another tool that would improved lap times and would prevent flat spotted tires.

Street guys? ABS and traction control are cool options that are not necessarily nannies and can improve the experience. Especially in a high powered variant.

Nice.

If anything, measurements and data collection is always a good thing.

These old cars can use more of those in the drivetrain for easier troubleshooting etc etc.

These are all learnable skills, The more talent you have the better your lap times without extra hp or nannys , sure build a good racing car , just nothin but talent for driving .

How do you think Bob Bondurant handled the cobras so well ? Pure Talent . Yep Pure Talent.
On the other hand , if you are lacking in talent then by all means go with the nannys , but that is like comparing apples to oranges .
Remember this is just club stuff, just for fun , to see how good you can get with what you got .

I just promoting the Idea of learning how to be the best driver you can with no nannys .

Still trying to figure out the front. There doesn't seem to be any solution that's "universal"

I'll probably build a setup that works off the 2 part brake rotor bolts for my own car.

I wish there was a setup that could be made to work with the bearing / hub, but I can't figure out how to do that in a reasonably easy way

This is for racing style traction control, datalogging and possibly Bosch motorsports ABS. Not some silly Nannys

[TopTuning]

I'm also running a 996 NA getrag 6speed (no vehicle speed sensor equipped) with a 964 speedometer (electronic)

I was nicely running a speed sensor just off the 6 axle bolts, but this will give me resolution below about 8mph. Not very important but as a tuner and electronics geek, I want to see high resolution speed data in the datalogs ALWAYS.

This also allows for some fun idle tuning / transitions / throttle mapping at low speeds. Your modern, daily driver does all this stuff, making it easier to drive. I've already implemented a idle "bump" up feature when the clutch is depressed. Makes an aggressive clutch more friendly and improves anti-stall characteristics.

My math with these sensor rings and the MoTec wheel speed sensors says they will give a clean reading from about 1mph to 700mph (10hz - 10khz sensor)

There isn't a human alive that can out perform modern, racing style ABS and traction control.

This also opens up the possibility of brake based torque vectoring, which no mater what you do with your feet, you can't beat.

[dannobee]

I already worked out the front sensors for a G-body.

You are wrong, Ian. These are not all "learnable" skills.

The only one you could argue about is traction control but it is banned in F1 because it is too much of an advantage.

Bosch Motorsport ABS cannot be beat by a human as it controls each corner individually. I don't think your Kermit has 4 brake pedals.

Your "if you are lacking in talent" comment, which you can stick up your butt, demonstrates that your thinking is from the 1960's. Traction control and ABS are not stability management. They don't replace talent. The best drivers are still the best when these tools are available. As for street guys, these options make for a safer experience without
removing skill from the equation.

Yes, your solution is the best I have seen. I wanted to see if there was a different solution...

Nice school yard thought . I will give you choice of any two Identical racing cars , one with ABS, one without . Now you select a pro driver that you respect , you drive the abs car , and he drives the other . There is no way on earth you could even stay close with your nannys.

Funny, I never said anything about my driving compared to anyone, much less a professional. I'll indulge you and your argument for a moment anyway. There is a lot more to racing than managing traction under braking and accelerating when the car is not pointing straight. So no, I don't see Bosch Motorsport ABS or MoTec M150 traction control suddenly allowing an amateur racer to become as fast as a fast professional.

But, I would expect that pro to be faster and more consistent with Bosch Motorsport ABS and MoTec M150 traction control turned on versus turned off. Why? Because I have seen the data proving it.

[dannobee]

I'm with Scott on this one. About two decades ago there were some nascar cup cars that had illegal traction control, all controlled through the MSD boxes. The traction control could correct wheel spin in the time it took one cylinder to fire. It was THAT fast. When tested, even the best drivers in the series would magically become nearly a half a second quicker on a half mile track. When the word leaked out, nascar quickly started randomly confiscating MSD boxes and sent them in for evaluation. And that put an end to that.

This is awesome and I'm stealing it!

I don't know why i didn't thing about that type of sensor, with the 90 degree pickup. DUH


Thank you
