Thanks Pinhead
1bolt,
The testing you refer to, was it done by Jesse Lackman of RevSearch?
If so I'm very familiar with what was done and how the engine performed in the car
after the dyno. Jessie did a great job with the test keeping an open mind and tried
very hard to provide accurate results.
I have my opinion on why the dyno didn't show the same improvements we enjoy at
the race track. I'm thinking the 10% Klotz HiTRATE used to eliminate detonation
had a big impact on combustion. Jessie tells me the owner of the engine is thrilled
with the performance on pump gas with iron heads at 11:1 compression.

My opinion is more than just a gut feel. Some of the engines I have done have shown
as much as two tenths improvement at the drag strip and others have won multiple
track championships! Although most people want to know how much more power
an engine will make with the grooves, that's not why we run them. The primary reason
is because the engine runs cleaner. Nothing that requires any scientific testing, just look
at the plugs, exahust, oil etc.
