So I'm going to start up the beast for the first time tommorow and I'm wondering what I should gap my spark plugs at.

I'm only going to be running ~7psi for the time being. What do you guys run?

Setup:

te04h turbo
log manifold
2.5" charge piping
d15b7 w/ uberdata
450cc dsm's

So yea, what do you guys run?

 

gapped mine at .28

 

Can anyone explain gap at all? I'm a tad confused.

 

I'm running BKRE7's gapped at .030" and them seem to be fine.

You want to run a small gap on a turbo spark plug to reduce the chance of the spark being blown out from boosting.

 

SO the stock plug for the d15b7 is the zfr5f11

I'm wondering if NGK makes ZFR6F11's? As i understand that would be one step colder?

I can't seem to find any colder plugs in my area. Suggestions?

 

Your going to have to special order them. Stay away from platnum and iridium plugs on a boosted car.

I still don't understand why you can't use iridium's, they have a higher heat
rating then the v-powers. I understand that copper is a better conductor but
with the smaller point and the correct heat range I can't see the spark
being that much different. Is there actual proof of why not to? Or is it hear
say?

 

anyone??

 

use ngk bcpr-7es,they work great.....

I know you don't use the platinum becuase it gets super hot and can cause detonation. I would imagine that iridium is the same way. The reason they work so good is how hot they get.

 

I run BKRE7's and they are gapped at .28.

 

got some BKR7E.s and gapped at same magical .28

but I might try the bcpr-7es like AL.RODD said

 

I'm running NGK R5671A-10 Gap at .028

But the iridiums are made for hot applications the heat rating is alot higher
then the standard ngk's.

Right so are the platinum. The problem is the tip gets really hot. It becomes a hot spot in the combustion chamber and can cause detonation.
