yeah 7's are probably the way to go in a TT, i think ill change mine . personally i think 1.1 is too much in a TT with high boost and/or aging coilpacks
because under high combustion pressures it is much harder for the spark to jump the gap, so in high compression n/a or boosted TT a smaller gap is generally used. ageing coilpacks also dont put out as much spark as new ones and cant jump a 1.1 gap so you get missfires under load
wouldnt that mean that you would want a shorter gap length in order for the spark to not have as far to travel?
thats what i was saying aswell lol meh i dont have a tt anyway its just common sense that if you want it 2 run better on boost then you would want a plug thats gapped shorter
Stock gap for TT is 1.05mm. You really want the largest gap you can without plug blow-out. 0.8mm gap is used all the time in TT's because of blow out under load/higher boost. The better solution would be to get some good aftermarket coil packs like splitifre, hks or even some bosch coils then keep the gap nice and big and get a stronger spark. I use 0.8mm gap on pretty much all boosted TT's because people don't want to spend the dosh on the good stuff. It works just as well though. And for the high boost, colder plugs are the way to go; 7's in street cars and we run 8's in a lot of our drift cars.
