Here is the last dyno pull on Matt's car the night he brought it over before doing repairs to the car and adding boost. As you can see I sent the car out with a 11.5 A/F at around 8 psi in the top of the RPM range. To be honest I do not have any text messages from last year. I wiped my phone clean New Years day. I am only going from memory here so I am not going to get in a debate what was said and not said. It seems to me between the boost leaks, exhaust leaks, and a boost controller I remember seeing a text from Matt saying he got the boost as high as 13 psi. What I do remember is telling Matt we need to get the car back on the dyno given the amount of boost increase we were dealing with. He asked me if it was ok to drive it untuned for the increased boost. I explained to him to use caution and drive it easy until we can verify A/F's and timing. With the car making close to 600 wheel horsepower at 8 psi I imagine it had a decent jump in power at 13 psi. Again this is providing that the car did see 13 psi of boost.
Lot's of variables here folks. I can not remember the compression of this motor. Between pump gas, 13 psi, and no tuning up at these boost levels it is hard to say what caused the failure. One would think it it would be over 700 wheel going from 8 to 13 psi.
The purpose of my post here is not to Slam Matt or make excuses as to why he had lost his engine. If someone cares to share this on the Corvette Forum you have my permission. Matt, If I am going to be tuning your new combo again I want to make sure we have all our "T's" crossed and our "I's" dotted so we can do our best to make sure we do not have another engine failure. We also need to make sure all parties are comfortable as well.
Last thing I am going to say here. Let this thread die and come this spring come out and meet some of these people here on the forum. There are number of people who I consider my friend's posting in this thread and are good people. I feel lucky to have a number of them as my friends.
