TPS Vs RPM
After A little three months of engine running
We open engine a apart for some upgrades we notice that there is pitting on the pistons on the exhaust side.
Wondering is it piston is not genuine or there is a problem with my timing table, do think that the numbers in the table are very very minimum?
Did check for Knocked with Links knock equipment, no sign's of knock.
Wondering which part went wrong that cause the issue.
For fueling AFR is around 10.5 at WOT, engine make 354 WHP
Already did check for timing drift there are no signs of it drift from 1.5K RPM to 4K.
This have been hunting me for the past week, hope that you guys can shine a light on me.
