Post Missing Effects

I have a little miss if I put the foot down hard and it comes onto boost.

Ofcourse, this could be coil packs on the way out, maybe the ignitors aren't strong enough, maybe its just rich and retard. I'll work towards that one in the future.

One thing I have noticed, which I find interesting, after I have this little miss at say 5,000rpm, the car sounds different aftwards. Not missing, just a little more fueled up. Few more pops for a while.

Also, I have blocked off the BOV outlet and run a POD. I can really here it whistle when its cold and just started up.

After a little miss, its hard to hear at all. At first I thought i'd blown the turbo.

Do you think when it misses, it increases exhaust temp and this is transfered through to heat right through the engine bay?

Do you think this extra heat is causing the huge difference in the way the turbo spools ( at least to the ear ) and changes how much fuel is being dumped in to combat that heat?

I ran standard boost and the car is standard.

OK, well I'll assume it is heat then and a front mount and reduction of inlet temps will help spooling of the turbo.

Hopefully the SAFC helps it out a bit...

the intercooler well help drop the temps after the compressor outlet but if its sucking in hot air in the first place, its still going to be hotter

OK, but what I'm really wondering about is...

why does a few pops and a bit of missing from 4500-5500rpm suddenly make the turbo sound different and not want to build boost as fast???

then after a while, its very audible again and building boost quickly?
