Spark plug gap?

[SKREMN]

I'm running NGK BKR7E-11's copper spark plugs in my car
B20 vtec high comp
i've got a MSD 6A unit and external MSD coil with 8.8mm leads
should i increase the stock gap to bigger then 1.1?
or leave it?
I was thinking with the stronger output from the MSD units I may be able to increase the plug gap or am i wrong?

thanks for that i might as well give it a go i can allways bring them back down
how much bigger do you think i should go?

and can anyone else back up claymore

go 1.1mm, its also still with in Hondas Specs.

going 1.1 is the stock gap size therefore i'm not really wideing the gap...
is it better not to go any bigger?

trial and error,

you have nothing to loose, try 1.3mm and see what happens.

you have a pretty strong ignition system thier

Thanks I will give it a go i'm shure improvments will be marginal but i'll post up how i went

with an msd unit i'm pretty sure you can go way bigger than 1.5mm

i know coz i only have an upgraded Crane Cams LX91 ignition coil (with the stock dizzy) and it sparks nice and fine on 1.3mm using the same plugs on an sr20 (but 6 heat range and measured using gapping tool and vernier calipers). at the same time though i increased fuel pressure gives it a nice noticeable increase at the butt... however dyno will tell which it should!!

on a side note, when my car broke down last week (unkown ignition prob at the time) the nrma dude had a test plug rigged straight to my coil (not one of the plug leads) and i swear the plug had at least 5mm gap and it still sparked mad... no bullshit!!! <-- ***EDIT*** someone has kindly informed me this is due to different combustion pressures compared to atmospheric so disregard ;)


***EDIT***
also, use a fresh cheapo copper plug for testing, you can't keep regapping your good ones especially since they get exerted to extreme CC heat.. they'll just randomly lose their set gap as you would have softened the opposite end of the electrode.
