So i've been seeing people saying that SAFC will fixc the coil pack problem. Is this correct? If so, Power FC will do the same but more right?

If the sparks are leaking out of your HT ignition cct it is only going to get worse. Coilpaks & all types of insulation for that matter, age & eventually develop miniscule cracks (leakage paths) sparks burn, make/follow carbon tracks, line of least electrical resistance. Answer = Splitfire or in any event replace offending coilpaks with known good items.

no, niether is at all true. search.

arcing of the coil packs is due tothe resistence inthe electrical path being greater than an alternative route for the charge to escape from ..so the "spark" side steps the plug and either wholey or partially earths onthe engine head. this results in a weak spark at the plug and thus missfires. when hot (eg under load at high revs and when engine up to temp) this resistance increases so therefore the missfire ets worse.

as the other guys have said only option is to repair the brake in the circut. this can only be done by replacing the coilpack with known good ones.

as this aint cheap first check youre running correct plugs and that the afm is ok and air filter clean ...(carb cleaner)

im buying spitfires next week. as my coilpacks just died.

    • Hey Murray, hope all is good. I took your advice and put the filler first then the putty. Seems like a much better result but i noticed there are still pinholes. I even had pin holes when i initially put the putty on the body filler. Do you think it has something to do with my spreader being f*cked? I attached some images. This is the intially body filler i sanded. No putty yet  Applying putty. Final result after using wax and grease remover can see the pin holes. I just noticed as i look at the putty application it looks wavy not sure if it's supposed to be like that or because of the spreader.
    • Hey all just wanting some advice. I’ve just compression tested my RB25det and these are the following results  Cyl 1 - 135psi Cyl 2 - 135psi Cyl 3 - 120psi Cyl 4 - 140psi Cyl 5 - 130psi Cyl 6 - 125psi   do these numbers seem ok.  Thanks in advance 
    • I must say - this is how I picture all R31s!
    • Rust repairs completed, doors back on! pretty much totally back together running now. All future repairs will be fiddly wiring getting everything back up to road condition.  hasn’t  taken that long considering the condition I got the sub. note my helpers keeping the back seat warm 😂
