Good to see this! I've been running BKRE7's at .020" on E85 and still have random misfires. Going to try gapping tighter, to see if that helps.

 

Yea I had to go way low on mine, but once I got it down there I never had anymore issues. I run a similar gap on my dad's car on e85 as well. No spark blowout on either car with this gap.

 

U could always run a kbas. Then u can run stock gap.

 

Im runnig the KBas at max voltage. ~20volts. No break ups on BKR8 on stock gap at 17psi.

Was running stock coils and was getting severe misfire / breakup in the 6k rpm range in boost even with the KBAS. The misfire devoloped all of the sudden. It Only misfire in boost above 12psi. Changed out to new RSX coils and no misfires since.

 

What's KBas?

 

Kenny bell boost a spark. Had to gap by Ngk's down to about .019 to get to 18psi with meth.

 

Lets say I have a pet goose that lays golden eggs. So without the concern of cost, how do the Okada coils compare to BAS?

 

Bas>okada coils.

 

making 800 at 30 psi, stock coils, bas, bkre8 gapped to .25
