In using out water/methanol design for five years it was time to check and see how engine is doing with the long term use of water/meth.

Results below and we see even using E10 gas with our 1999 LS1 that is 372 stroked and 11.3:1 compression still has zero engine knock or misfires.

Weather was only 60 degrees so if anything a tweak of tune could be done to lean up AFR for part throttle just a tad for winter weather.

This run was not about maximum performance but how engine is doing with different engine loads seen in daily street driving
