I had a tiny miss at 26-28. Using a M&W cdi. Went to .022 and smooth as. It would just depend on your particular setup. They're all different. Went 9.88@145 mph on 15psi with that tiny gap.

What spark plugs are you all running with E85 and Aluminum heads?

 

[TT/Ameasap]

I ended up running time in my sig with my small gap. Smooth as butta now.

 

[MikeL.]

Nice...turn up the boost. That turbo is night and day difference at 25lbs.

 

[TT/Ameasap]

I ran 23psi on 93/alky a few times on the street. That was about as fast as I wanna go with non prepped surfaces

R42TS .030 28-30 psi

NGK TR5 .028, Stock coil,@ 29psi

Ran the E3's (E3.42) with the supposed pregap of .040 and it was lighting off 25-26psi no problem with a pretty fresh stock coilpack and newish Accel wires.

When I go WOT, sometimes the car feels like there is extra vibration but the power is there and the car pulls hard. It's not the driveline, the sensation is from the front of the car. This happens when approaching 20 psi boost. Is that a symptom of spark blowout?
