Well Gurus, I wish I had better news to report from the first race of the season but it just didn't work out that way. The new MT 275 Pro Radial tire has proven to be a major challenge for me. I went out for first round qualifying with what I thought was a very conservative tune up, intending on going A to B, just to see where we were. Didn't work out that way. This happened instead. |

Wow, that's a tough break. I'm glad you and the car survived, though.

Good driving, that you held it straight is what matters.
Crashes on the strip are usually pretty bad. |

If you can't run wheelie bars how about a sensor?
Not traction control, but tilt? |

I don't know how I would even do anything like a tilt sensor. My car is bare bones pretty simple as far as electronics and engine management. The only thing you use it as a trigger to kill power, would be ignition retard or nitrous activation. As far as traction Control, Davis Electronics makes a TC box all the "street race" guys run (we run them in our dirt late models as well) but it's like 5 grand and my class can't run them anyway. Really the best thing to do is to use the suspension to keep the car on the ground and pour all the HP I can to it and get it down the track as fast as possible. You'd be amazed what limiting the front travel (extension) or using a strap/chain to terminate it abruptly, will do.... Also I got be better prepared as the driver to recognize what the car is doing. This was the first nitrous pass on those 275 radial tires and I (as the tuner) just misses the set up, then missed driving (as the driver) properly.... lol. Will |

You sure don't have a LACK of traction.
Glad you are ok... that had to be scary. The rear tires were off the ground... a little more speed there, and you could have gone over. I look forward to hearing about the solution. |

Is the bump adjustable on the rear shocks? If so, was it set soft? |

When you say "Bump" on the shocks... typically that means the compression setting but I just want to make sure...
My rear shocks are Penske 7500's. They are common "double adjustable" with separate Compression (40 clicks) and Rebound (19 Sweeps) adjustment. Clicker adjuster (actually an allen head) on the compression and then a sweep window near the top of the shaft for the rebound (what a PITA to adjust on the car). I have them set dead center, 20 from loose on compression and about 3/4 tight, 15 from loose on rebound. The front shocks are Viking double adjustable but they use clicker knobs for compression and rebound. 19 adjustments for each one. I was 10 from loose on the compression and full tight, (19 from loose on the rebound. Will |

Somehow, I missed this post. Yea, bump = compression. My only thought at the time was that the rears were a little soft allowing the rear to squat very fast making it easier for the front end to come up. |
