i have a b18c1 with a drag gen 3 kit with 310cc injectors running 6-9 psi of boost how much ignition retard should i be running with the colder 7 series plugs from ngk and how much should it be if i had stock heat plugs? i am useing .5 of a degree with the colder ones is that to much or to little?

 

is there anyone that is using a BTM on there FI Honda/Acura?

 

1/2 degree per pound 16 degrees base timing.

 

i'm using .25 for street and 0 for track. thats w/ 9psi on an LS...i wouldn't try that w/ a gsr though..

 

i am at 16 deg with .5 per psi with the 7 series ngk plug

 

another thing when i was on they dyno, butting the btm to 1deg took almost 20 hp out.

 

i dont know if you can use it on anything else because it is boost dependent.

 

i have felt the power drop to at 1 deg i went down to .5 but dont know if i should go farther i might with the colder plugs

 

is that 20hp drop from 0 deg to 1 deg/lb or what. wow, you run 0 deg at 9psi at track.

 

is that 20hp drop from 0 deg to 1 deg/lb or what. wow, you run 0 deg at 9psi at track.

i have mine at .75 deg/lb with stock timing at idle. also using ngk 7 heat range.

 

i am running stock timming and .5 per psi on the btm is that too much or can i go lowwer? i also have ngk 7 heat plug
