What plugs gap's and boost you gents running
Turbo Mini Forums

tried a few diff combinations now and still having missfire troubles under boost :( uspect the crappy rover ignition coil but wana get the basics right

turbo 16v k-series 11.9@118.9 :)

running about 1mm gap with megajolt and 20psi.

balls to the blower!!!



1330,stage3 head, gt1549, canems ecu, S/C box and drops

what coil? the edis one? and what kind aplugs, cheers :)

NGK 7's, 25thou gap & up to 16psi.

champion C57, Rover (sagem) dizzyless coil pack, 30-thou gap, 16psi.

was running NGK BPR7ES with .8mm gap, jolted and 15psi.

Erm,

with the C57's are you running an ecu? if so do the C57's not bugger it up being non resistor?

whats the resistor value?

wel i think i sorted my missifre, was simply that i was beeing way to carefull awith the ignition timing, whacked 10 degrees onto what i had before and car pulled on boost to 7.5k.

with the C57's can you use standard ford "edis" coil leads, as i notice the edis pack i have jsut aquired has a weird fitment..

Interesting,

When I was test running my megasquirt on the dining room table with std non resistor plugs and a ford coil pack and leads the ecu and laptop kept locking up and crashing, changing to resistor plugs cured it,

mind you the unsheilded plugs were about 2 ft from the laptop and ecu....

i think i checked my edis leads at around 10k ohms ,eeek i thought ! im running non resistor bp7es at 35 thou,6 psi at mo .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

A resistor champion plug has to have a Q or and R at the beginning - not the end of the description.

The actual plugs in mine are QC57C
ie CDI resistor, 14mm, 57 heat, copper plus.
I'll be trying C57C plugs next year - basically to see if i can (they're all I can get over here). I am running magnecor resistor leads incidentally.

If i run the champion race plugs i'll be stuck with no resistor, as i'm on 10mm plugs.

I'll just have to see if i can get away with it!

I didn't say that C57R's don't exist - but if you look at the Champion specs, the designation of resistor is either Q or R and before the numbers. Going off the 'R' after the letters - that designates 'push wire' (whatever that is) at the firing end ?
I don't see why a global company would change its designatory specs for different markets?
