Are these equal to the bcp7res plugs? I want to give them a go as I heard they are better than regular plugs. I'll check my shop if they stock then. Repco is the biggest rip off. They want more than 5 dollars per bcp7res. I get 6 for 21

I was running bcp7res and i recently replaced them with bcp6res and the car doesnt feel responsive down low. it actually feels laggy and sluggish however it revs all the way to redline.

My car is making 256kw atw and i run splitfire coils, through trial and error i have found a happy medium gap of 9.5 on any ngk plug i use, this gap provides me with smooth revving all the way to redline. this is the biggest gap i can run without any misfires. I have run the BKr7e v grooves in the past and these definatelty felt the best alround. Problem is i cant find them anywhere.

I think i made a mistake in running a 6 heat range as the 7s seem to perform much better

Any opinions?

All good guys , Repco have them on the shelf

thanks for your help

How much a piece? I'm definitely going to give these a shot. I would love to try a larger gap but honestly, the pain and f**king hassle of removing the plugs, adjusting gap, running high boost and checking for miss well.... a pain in the ass lol. Next set ill try a .9 gap from my .8 and see how I go. Ill pull as much timing from my tune and run it incase it decides to miss it should be cool enough not to det. Yes my car detonates on high boost if it misfires(too much compression maybe?)

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
