exactly. They didn't bother with the 6 bolt as the larger diameter of the studs, holes, threads didn't warrant that style of stud. The ones in the 6 bolt haven't met their limits yet, at least not that I (or they) know of!
Yea there is definitely something fishy going on. Are you feeding it from the OFH or the head?It's possible that the pressure relief valve in the OFH is gummed up or stuck, causing oil pressure to get out of control above 6000rpm. It's happened before.
@ 2 bar i'd use their H11 head studs. I have them on a built engine ready to push 45-50psi with a borg, and from my experience as well as others the MAP h11's are beast and worth the investment
The ECU does send a signal to kick on the relay for the fuel pump, but to be honest, you're on a 420a, and that's completely out of my range of expertise lol.If it was a 4G i'd know more, but idk shit about the 420 ecu or wiring, so i'll let the NA gurus chime in
You could also feed from the head like these ^ guys lol...If you go that route, make sure you plug the filter housing outlet with a bolt that is BSPT (british standard), not NPT. I can't tell how you many people i've listened to wonder why their filter housing cracked or is leaking when they...
which is why you should put it on a JMF Drag manifold, works beautifully :o)(except its so damn big and sits so low on that SMIM that you need to eliminate heater core hoses and all kinds of other sh*t)
regardless of its location, if you're blowing fuses that fast I would once over all of them and check if anything else blew. Clearly there was some sort of short/power draw causing this.
+1 for adjusting the greddy, but that may or may not solve your problem. If the bov is leaking from the seal, adjusting it will do nothing. It might make a minor difference, but it will still need to be fixed.
If it fires from 1 wire on a coil, it will fire from the other. The transistor, as well as all other ignition electronics are before the coils, so they will not interfere once the current reaches the coil, only before. The coil fires both wires/plugs at the same time, hence "waste spark"...
