The deal is if you run more boost the gap needs to narrow from stock (per above) a bit to prevent spark blowout.

that Hyper link is only for heat range 5 and 6 does it matter the gap if i have heat range 7 ......since i am running more boost then stock how much narrow does the plug need to be? anywhere from 0.8 to 0.039?

With that plug, I'd gap it at 0.028" and give it a try. Every engine is different when increasing boost...you are not going to get an exact answer (but lots of opinions though )

thats all i wanted to hear 0.28:icon_bigg....just for the record when boosting more then Stock every Supra has a Different spark plug gap?:sarcasm: there is no certain number correct? the only fact is that the more u boost the small the gap??

Like I said, it's not exact. Old coils vs new coils...cylinder compression...spark plug wires...etc all have an impact and once the mods begin, each car becomes more different from another. You just have to try it out and adjust...in general, the more boost you run, the more narrow the gap (to a point). What I told you is what I would do

thats all i wanted to hear 0.28 :icon_bigg

I really hope you don't gap at 0.28"...over a quarter inch would be a bit much

what do u mean by that ???

 

[jdub]

Dude - Read what you wrote (.28)...that's over a quarter inch. I said 0.028"...big difference with the zero behind the decimal. I was busting your chops a bit
