TR6 , E85 what plug gap to run ??

[dynoman]

I just installed my TR6 & new wires and was wondering what gap should I start at ? I'm running E85 with NGK UR6 plugs . They are currently gapped at .028" Thanks , Sam

I have been told you can run the gap to .035 with no issues.

Start at 30, then try 35, then 25.
You will need dyno time or track time.
Swap out the three sets and see if you see a loss or gain.
This is really the only way you will know.
