Default 300 mile plug check....how do they look?

Running 6psi on a GSR.

Plugs are NGK-R's...BKR7E's I think. Heat range of 7 for sure.

Labeled the way they were removed...from right(1) to left(4).

I think they look fine. What managment are you using? The gap doesn't look too small, but what is it anyway?

Gap is between .028 & .032

Engine management is Hondata S100B w/440cc's and Walbro 255 pump.

OT:what kind of power are you making on 6psi?

for 300miles that is about right.
if they look like that after 3,000 miles your definaly getting lean too offten.

Hella_JDM- The car made ~18 dyno pulls during tuning this past Monday. Since then I've probably done about a dozen WOT pulls on the street.

Charlie Moua- At 6psi it made 212whp with a leaking wastegate which was causing extremely late spool up. It made 232whp on 8psi as shown here- http://jtaylor.u24.hosting.thr...0.jpg

Notice the late powerband. Heh...
