Re: New Technical Inspection Addendum
Maybe some of the COPO's owners can answer this one. I'm not pointing any fingers at anyone but I was told some of the COPO's come equipped with a delay box built into their ignition. Is this true? Barry

Re: New Technical Inspection Addendum
I was involved in a race once that seemed odd to me... That being said there was about a 98% chance I was beat anyway...I was .03 they were .00 ..
they spotted me around .20 1/8 mile @ 330' I'm watching the nose of their car through my quarter window and this car is surging... coming up on my door and falling back to quarter window about 12-18'' THE STRANGE part to me is front of car is NOT bouncing or moving... front stays hiked up... no bounce.. nothing like it is full power... then a little before 594' he quits surging and pulls up puts his fender out in front of me and backs into me... YEAH I KNOW I was a sitting duck,but how was that car moving back and forth beside me slowing and speeding up enough to move 12-18'' beside me without the front end raising or lowering any? maybe front of my cars are just loose... but if I throttle or pump the brakes under power the front of my car is going to raise or lower some....this car NEVER change height AT ALL.... |

Re: New Technical Inspection Addendum
MSD grid system .race park. System
Can I ask why this is ok in stock or super stock? Can of worms. I don’t own one. But it does have timing adjustment ...traction control? and I believe GPS. Or something to the effect of plotting your run down the track On a no computer car easy to check. Late model 2008 or newer car. Needle in a haystack Oh yes people are cheating in plain site. But it’s ok MSD. Motec. Racepak. If you one of these

Re: New Technical Inspection Addendum
Does this mean that my wife will have to rename the line on the graph that says NOS "in' and "out" ??

Re: New Technical Inspection Addendum
I have been involved with the COPO program from the very beginning. I own the sixth car built. Holley has been involved in my program since early 2013 when I converted that car to Holley EFI. I have been closely involved in both programs this whole time. All I can say is, if there is a "Factory installed delay box," it has been kept well hidden from me!

Yes, you can map the timing on the MSD Grid to each individual cylinder and more. As DG explained earlier, there are a lot of different ways that you do so, especially with the high end ECU systems and their interface with the MSD Grid and Racepak data. I did a brief stint as the Chief Engineer of a shop that built racing engines for Trophy Trucks, ATV's, UTV's and also prepared them to off road races. We used probably every ECU available in the market depending on the customer choice. All I can say is that with the higher end systems like Motec, Entrom, BS3 and Holley, you can basically have the vehicle do whatever you please and do it in a discrete way that tech will not know what is taking place. It also requires the tuner to know what he is doing and have knowledge of the type of racing too. As an example, with the high end Trophy Trucks, we had barometric pressure sensors that would change the tune of the engine almost instantly for higher elevations and change the tune at lower elevations. Of course, the high end Trophy Trucks cost a lot more than a Pro Stock when they are race ready. I strongly believe this same issue took place in Pro Stock with the advent of EFI and why the dissimilar performance among teams until others started catching up. |

Re: New Technical Inspection Addendum
Adger, you being a machinist it would probably be more suitable to change it to "Go" and "No Go"?
