Are you planning on rolling road before and after to see what difference this makes?
I get the lower temps you are recording but does that actually translate into anything useful?
You got lower temps? Can you elaborate
Sorry, I meant I understand the fact that you are recording lower temps. My question is does this make any difference to performance - and are you going to measure that?
Thanks
Mark

Well atm i wasnt able to log under full throttle and summer temps but like pointed out, the more heat you keep inside the exhaust, the less will fill up your engine bay. So the less "extra heat" the air intake will pull and cold turbo will absorb. The difference wont be that much compaired to water injection but at least you battle the source. Heat soak in the long term kils performance and engine parts.

Cheers :)...hm that you mention, totally wrong material (lets heat through instead of blocking)!
Will remove it, leave stock or check for better material.
Meanwhile did one downpipe. Only +-30cm from trubo downwards, witch is the place were the tunnel starts to open up again and hopefully most heat finds its way outside...
Still gonna do the other downpipe and call it a night :).
Hopefully it was worth something...
How's it going, do you know the manifold temp before and after the wrap?

See on page 7 (before and after temps).
*manifold:
Before +-300°c
After +-80-90 (yesterday messured a 120°c).
Still havent full pushed the car, to slowly 'burn' in the isolation, but i think it is save to say all shielded parts temps are lowered at least 1/2 to some even close too 2/3 :).

Fantastic, are you experiencing any mild power improvements?

Not really, but it is winter so the cold ambient air is cooling the engine bay already. Guessing when summer comes we will see some gains...over unshielded :).

Great find, im learning fast that water methanol is an absolute MUST

Still curious, afaik you need a custom tune that takes in account the methanol boost (basicly race fuel values i suppose). Just wondering, how the care behaves when it isn't beeing pushed and no methanol is injected (since our cars can't detect octaan levels).
My tuner hasn't answered me, in a way i would love to just water inject under boost/when IAT temps getting higher...and maybe seperate system or switch/tank with water/meth mix when wanted.

Who told you the ECU’s can’t detect octane? Water will half IAT’s with or without a tune

That is/was my general tought the ECU in our platform can't auto detect octane and adjust...
1. that is why apr for exemple offers several octane tune files (and you can swap afaik, but you need to load them into the ECU so it doesn't detect on the flow -> if injected).
2. with VCDS you can't read the octane level of fuel type.
That makes me curious how the car behaves when you don't use the meth all of the time and in my case it wouldn't make use the most of it (unless i tune for meth).
Fact is i been using a 1/10 mixture of bio ethanol (100%) in combination with my regular 98 gas. I don't know how equal ethanol and methanol are, in some ways simular (octaan boosters), both burn at lower temps and clean afaik.
The bio ethanol goes in my fuel tank (7l on full tank).

That is why i maybe should just focus on the water injection instead of water/meth.

And you receive more power with ethanol right? That’s because your ECU will advance your timing due to the added octane, tuners will offer different tunes dependant on fuel to be mega safe, and maybe even adjust boost down on lower fuel quality to reduce knock

I didn't change my tune after the aquamist instal. When the boost is low the meth is off and the car drives normally.

I see, cheers :).
Then i suppose the gains are 'minimal' and its first priority is cool things down, but nice non the less and that would be my goal aswell (some extra performance is always nice).
