Tommy Tape Silicon Rubber Wrap - $13 from bunnings. Has anyone used this to tape up their coilpacks because of a misfire issue and what r peoples opinions of this product? It says that it can withstand up to 200deg C temps only, but so is the Selleys industrial silicon 401 that lot of guys are using. I couldnt find anything good for 800C so bought this quality flexible tape which supposedly dosent come off like electrical tape. Phone dosent allow me to load a pic of the product :(

Do your have cracks etc in the casing?

If not then wrapping them won't do much as they are stuffed on the inside.

Only time wrapping them helps (and good old fashioned Elec Tap works) when they crack and arc outside the case

There is NO was temps will get to 800c on the top of the motor mate.

Inside the actual exhaust housing of the turbo, yeah maybe.

On my old skyline, it had Nitto tape. Never came off. Current one has.... Nitto tape too. Best shit.

I very VERY much doubt it will even get past 150c up there. Even at the hottest, the engine is still touchable up top.

Or just buy new coil packs.

My car rarely misses/pops/loses power, at least thats what it seems like its doing when it does happen, its only happened like 5% of the time on 3 or 4 days on WOT around 5000rpms and up all this time I've been driving. So could be anything really. Used to happen regularly before, after the tune with Nistune it went away completely for 5-6 months and then recently re-surfaced but only 3-4 times as I said so a bit confusing. I do run 0.8mm gapped NGK coppers...so thought, why not tape up the coilpacks and give that a go.....and Nismoid, I dont know if there are cracks in them as I couldnt see the last time I pulled them out- which was maybe more than half a year ago...pinch.gif

Think about what you just said. The biggest YOU CAN. If he can't run 0.8 then gap them down. Even with brand new OEM coils i was missing with a 0.8 gap. Now at 0.6 they are fine. There is nothing wrong with a slightly smaller gap. Do you think going from 0.6 to 0.8 will magically give you another 50rwkw and half your fuel usage??

the heat will still transfer through the bolt holding the coil to the head

Oh thanks for info pinch.gif ,

i may try few more on then see if that helps :thumbsup: ,

heat transfer`s regardlees that was just too see if it helped as coil pack sitting on head hurts more,

i looking at Heatshrink too see what happens with that,:thumbsup:

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
