Wilwood Proportioning Valve


Recommended Posts

For those that have one with the stock brakes, where do you like to set it? all the way out? all the way in (I doubt this). A couple turns in? I just fabbed up all new brake lines and put one on last weekend. I installed it under the hood on the firewall because of time restraints so I won't have the ability to adjust it from the cockpit.

Half to full back on a road course, depending on conditions.

If you have the time, change your mounting location for easy access.

 

edit - I posted quickly and did not give much info.

My 260 is a well prepared, mostly gutted track use car without coil overs and the L series engine still kick`n.

It`s set up for track events and handles well for not being a "race car".

I have the non-vented Toyota calipers up frt and drums in the rear.

I use Carbotech (panther plus compound) pads and shoes and run Hoosier racing radials.

And I do ajust the shoes after each outing (after a little cooling down)(the tire and brake compounds I run alone would make "my setting" differ from someone elses setting)

John (as usual) said it best, test, try this / try that.

I have been on track at Summit Point and VIR only (both several times).

I find my settings to be pretty consistant at both tracks (with simular conditions, wheather, heat, etc.)

Now as far as the placement of the pro valve, I wanted to be able to adjust the brake bias on the fly (if it rains I`m not coming in to make ajustments)(and by the way some of the best learned skills were on a wet track)

I`m only offering my opinions, not what the "hot set up" is.

Test, test, test, test, and test. Put some used, but not worn out tires on the car ('cuz you're going to flat spot them) and rent a skid pad or find an open test day at a local track.

I'm lazy and don't want to test. J/K. :lol:

 

The reason I ask is because my car with be coming out of a 2 month

R&R on the shell straight onto the trailer and to the road course event. I won't have any opportunity for testing other than a warmup session saturday morning. It was a bare metal stripped down shell a week ago and quite a few things are new and will be track-untested. I'm not cutting corners really, but with my time contraints, at this point I'm not obsessing over the "ideal" either.

 

I'll have two sets of tires, a set of Hoosier bias road race slicks, and a set of Kuhmos. Maybe I'll kill the Kuhmos first.

 

The hot setup would be dual brake masters with adjustable bias bar on some reverse hanging tilton pedals and in-cockpit reservoirs. That's what I told my better half I wanted for father day, and the cost ...... But she didn't get them for me :cry2:

Don't need to go that far. I've got a nice custom bracket that fits the balance bar and two Tilton MCs to the stock brake pedal. I called S&P Engineering today (they deisgned and built it for me) to see how much they would sell the bracket for.

I'm interested.

I had a thought about how to set the proportioning valve. What if you took some sand to a parking lot, spread it out then used it as a skid pad. You wouldn't have to be going fast to lock up the wheels due to the sand, and you'd leave tracks in the sand so you could tell which wheels locked up first. Sweep the sand and try again.

 

Any opinions ??? It'll be a while before I get around to trying it, but it seems like an easy method. Of course you guys near the beach would have it easier than most of us.

Well I started out two turns in, the rears didn't seem to be getting very hot, so I put another 3 turns in, and that seemed OK too. I did't get enough time to really dial it in though. I crashed near the end of my second session - just as I was getting a feel for the course.

Has anyone driven a car with racing pedal setup like Tilton or Wilwood? Does it feel different than the normal vacuum-assisted braking? Does it require more pedal effort or distance? Can they be set up with ABS?

 

I've only see brake/clutch pedal sets. How 'bout gas pedal? Use the stock one? That'd look kinda awkward, wouldn't it? Where can I look for racing gas pedal to go with brake/clutch pedal set?
