I have several pulls to redline, many WOT runs, dyno pulls, etc. Does this mean my rings are obviously not .007 because it didn't fail yet or I'm just rolling the dice over and over?  |
No reliable way of knowing what your rings are unless you take the motor apart. In which case, you could obviously fix them or install forged pistons and new rings.
The reason that I am stressing this ring situation is, most of the posts on the board about supercharging the LT1 have been painting a pretty rosy picture. This gives something of a sense of overconfidence. I myself bought a supercharger with that incomplete information. Now that I know the risk when using the supercharger for my purpose (long runs) would have been very high, I gave it up. We need to make our individual choices, which are best done with more information.
Since Mr Jannetty is already tuning your car, then the things he discussed about reducing the heat in the rings via the tune are probably already in your tune? As far as extra steps to try reducing the heat, there would be adding water/methanol injection or straight methanol injection. Yet another would be to convert to E85. This last one for you, I think that you'd probably have to go back to a larger pulley (slow the blower down). Less boost would be because LT4 fuel parts are not very big, so I tend to doubt that they could handle E85 with the blower spinning this fast with the 3.7" pulley. You could ask JRE (your tuner) about these ideas if you want to try one of them. As previously mentioned, these types of measures could help reduce heat, but if there is a mechanical problem, they will not fix it.
