Kendall you just confirmed my desire to get a better ignition system. Although stock works great even in heavily modified cars, it has to be in top shape to function well. I had the same thing happen to me during a dyno session.
Clinton, I hear your concerns regarding the stock ignition system - but here's my observation.
For the Heffner TT's, we are seeing max boost pressures of about 22 +/- 1psi before we run these cars out of fuel. So, while the turbos can do more boost, unless we start modifying the fuel system, we're gonna hurt something! On the ignition side of the equation, the cars seem to be fine with a .024 plug gap. Yes, that is small but it really hasn't given us any problems at all**, and we have probably around 50 1-mile runs between Tom, Terry's, and Kelvin's car with this sparkplug config. **OK, we DID have our first problem on the dyno with the plugs but the concensus is that C16 leaded race fuel and putting around town on it, is a recipe to really hurt the plugs. Perhaps with better ignition system, we would get a better burn under this condition, but who knows. Anyway, it seems that a good solution is to better manage the use of C16.... keep it for the track events and then try to go back to something less corrosive for everyday driving.
Was this the 1st test of the digital boost controller since they were installed? I will be listening for the updates on what cause the lack of boost control
No, this was not the first test of the digital boost controller. We had previously set up the boost controller on AlohaGT's car - where it performed flawlessly out of the box, then we did Tom's car which we also dyno tested (the 1019HP pull was when we were dialing in the controller) and finally, we have done Terry's car. All have worked perfectly. Based on our findings, I would say that the boost controller performance is no longer a suspect in Chip's car either. Remember, we switched to Aloha's solenoids and then finally to complete manual control with no difference in results.
I am a very strong advocate of this controller based on our experience. Each one has work perfectly and consistently. Programming is very straightforward and easy. I will keep you posted on what we find out on Chip's car. Since running 220+ at a mile event (where he obviously had 20+ lbs of boost), the car has been in at least one other shop and has had additional (albeit small and easy) mileage, so we just need to make sure everything is as it should be.
