I was expecting animation with narrative from the science guy.
Nice work. |
Very cool.
A lot more holes to plug in an OE sub, but it might be doable. |

Mark, Is it safe to say that a majority of the cars on this site would see a disadvantage to this set up? I distinctly remember Wilwood telling me that many don't get enough heat in the brakes to make them perform at the top of their capabilities in our segment.

I expected that some of work you did on the new Z28 would trickle down into your new 69..
What are your thoughts on traction control for these old hot rods? Currently researching Racetronix & Bosch Motorsports ABS.. Quote:

On most Brembos they have a clear coat. Look at CTS-Vs at a track day. If the guy is on it, his front calipers will not be silver they will be gold. At work we get them to a carmel color. On that note anyone doing hard track work should run a high perfromance brake fluid. I change mine twice a season. ABS brakes also drive rotor temps up. ABS also allows later braking points which means you are trying to get gid of more heat over a shorter period of time. If you are braking at the 5 going into a turn and I'm braking at the 2 my rotor temps are higher and I'm going faster. Thanks Mark |

Not until the Z/28 was PTM (Performance Traction Management) ie Traction Control equal to drivers best effort or in some cases better. The other thing about PTM is it is much easier to drive fast. BTM is very complicated. It is a fully integrated system that uses the following sensors: Throttle position 4 wheel speed sensors 4 suspension travel sensors Lateral sensor Longitudinal sensor Yaw sensor Tire Pressure Sensors All this feeds into a predictive tire models that predicts how much power the rear tires can take. We even use the suspension travel sensors to know if the car is airborne so not to cut power when it lands (Flying Car Mode). So can it be done? Yes. Do I use it on my Hot Rods? No. I don't have the time or the money to calibrate it. At 875 HP the integration time takes a long time and a lot of tires. If I had a shop and sold cars to the public. (Not that guy in Woodland that can drive high HP stuff) I would think about slip based traction control to keep people from hurting themselves. My cars can do 3rd gear roll on burn outs! The pro race teams tune the TC systems to each track so it is easy. A one sizes fits all calibration is tricky. Mark |
