Traction control, wheel speed sensors... who wants 'em?
 

So I'm having a buddy of mine who works at a steel facility lazer cut a set of trigger wheels for the FC. These will be a 24 tooth count wheel cut from A36 mild steel. 5/16" thick in the front, 1/4" thick in the rear. They will both bolt to the back of the drive flanges.

In the front, you would need a GT101DC sensor, a 5/16" dill bit, and a 3/4" drill bit to mount them on factory ABS equipped knuckles. Or if you're baller like me, you have a 1/4" - 1 and something colbalt step bit. The better the 3/4" bit the better, as you need to drill out the cast iron or whatever it is hard as hell steel front knuckle to at least .7" to accomodate the sensor.

In the rear you would need to remove the drive flange, bolt them on, and press them back into the hubs. I didn't pull a measurement on the bearings as tyhis just now occured to me... you MAY be able to slip them on over the bearings, meaning press the entire bearing assembly out, slip the wheels on, press the whole assembly back in. Otherwise when removing just the drive flange, you are almost gaurunteed to destroy the bearings which cost $55 each.... You would also need to figure out a way to mount the sensor. According to my math, using a flat plate of AL, and bolting them to the dust shield bolts, you'll end up with ~.035" of clearance... it doesn't get much better than that.

This has the potential to be a one time gig, I expect very little to zero interest in these and thus there won't be any GB pricing structures so don't even ask ;)

We're also looking into getting them cadnium or zinc plated. After a year of use on my car, the fronts are showing age already.

So, if you're interested, post up....

Think Race Logic systems, wheel speed sensors, aftermkt speedo's, AIM or Racepack digital dashes, baller MoTeC Traction Control systems that I was looking at tonight and have built in 2-step and launch control... expect more fireballs than usual at this years DGRRXI, that and I think Dave's asshole might pucker a little when we dial this thing in on the street :smilielol5: I logged a near 4s 0-60 launch with the 6-spd and wheel spin at the top of 1st and 2nd :gnorsi:

Price might help..... Depending on the cost of the plating, price should be under $10/wheel but I won't know anything for certain until we figure out the cost of the coating.

Oh, and this is happening soon... like as soon as possible 'cuz I got a lot of shit to figure out on my car and I haven't even pulled one part off it yet for Deals.... and there's 62 days left, and I need to send shit out for ceramic coating, and plating, and powdercoating, and new brakes and yeah like 49 other things... literally, and I need to get on the motherfucking ball.

So if you want 'em, lemme know and how many.

So I would have to be able to break traction for these to help, correct? :rofl:

I'd be in (even though im years away from this) for that price. Final price is important though, but for $10 a corner, I doubt i could pass it up.

:lol: In a way.... yes.... Also consider swapping a trans to something that doesn't have a speed sensor, or running a different speedo... whatever the case may be.

Keep in mind this is ONLY for the trigger wheel. There is a $50-$80 sensor that is also needed.

Yea, but sensors you can get any time, these are one offs

Ohhhhhhhhhhhhhhh, i have another question related. Does motec have a TC switch, to just turn it off when you need to? Say in snow where spinning is better than not.

Yup, and built in launch control. Fully adjustable programable TC... Can't wait

Almost all aftermarket ECU's have a DPI (Digitally Pulsed Input) which can be set to a binary switch type deal (on off).

B, I may be interested in these, but I have to get my car setup and together before I go investing money like this. Is there any reason in particular you chose mild steel as opposed to another ferrous metal with less corrosive properties or are you planning on offering powder coating of the wheels as well?

(Ferrous non-corrosive metals include most stainless steels; T300, T400, T600, etc)

I was told to use mild steel for the best signal quality. When the .dxf are finalized I'm going to keep a copy in a safe place. From what I understand many of the lazer cutters won't take on a small order much like the one that's going on here. There are a few water jet co's out there that will, but they'll be more expensive. The one in the lic is a water jet piece, and it was something like $27... EACH.... so yeah, 3-5x the price for small shit.

I'm not going to powdercoat these as it may affect the pickup. Candnium or zinc plating is where it's gonna be at.

You have means to do that plating? I would think the zinc would be prone to flaking due to press fit and what not.

I know of a waterjet company that does a $150 min order for whatever you want (Regardless of what you want cut the minimum order will come to be $150, if materials and labor are in excess of that, the price is reflected to match).

Well... nevermind. I just double checked. The PS1k and PS2k don't have traction control based on wheel speed :(. They have boost control tables based on gear, but not wheel speed. :(. If that changes I may be interested in it.

I don't have the means to do that plating, but I know of a few co's that can, as does my buddy who is doing the cutting.

Nothing is a press fit either. The pressing is the rear wheel bearings in and out of the carriers to get the trigger wheel on the back of the flange.... thatnks for reminding me... gonna go grab a busted bearing and pull a diameter see if we can't make the wheel a little wider on the OD to avoid pressing the hub out of the bearing and destroying them. Pressing the bearing out in one piece as oppoed to pressing the hub out of the bearing. Anyone who has replaced the rear wheel bearings on an FC know's what I'm talking about.

That was about what it was up around here. I did find one down south that would just cut whatever. I used him for the original order which was average $30/wheel. Lazer is faster, and thus cheaper.

Blows.... Motec 1 Haltech ZERO!! AHAHAHAHAHAHAA:fawk:
