Cooler, faster, better... Turbo Wraps & Intercoolers

[HPRS230]

Anyone done any water spray intercooler mods?
Found a small kit (DCI) which is about 1L.
I also found a 100L weeds sprayer kit 4L per min.
Toying with the idea of 100L in the boot for a track day.

Brisbane is Hot atm that's all (35+) and I now have a JB4 so more heat

100 Litres (?!?) you will be slower because of the weight
Before the days of E85 I did it in may LAser Turbo Race car, you just mist it, 5-10 litres in more than enough for 20 minutes, if you have a temp based switch even better

I'm also toying with the idea of water/meth... Gotta fine tune the rest of it first, but would be beneficial - especially in this heat!

After the Happy laps on Sunday at Lakeside.
Ambient temp was around 30-40C

JB4 Map 1 and 2 ran well.
Temps were
Inlet: 40 - 50°C when at full throttle
Water: 95 - 108 °C (1/2 hour session)
Oil: maxed out at 114°C.

So maybe my 100L water tank is a bit over the top.
Would be nice to get the oil a little lower.

Yes 100L tank is heavy, but wouldn't need to fill it all the way once I had worked out how to deploy is to reduce temp.
Air flow is key, so If I say out of traffic, then all is well....

......But inevitably it collects moisture leading to corrosion - I see it all the time.......

Reading an old thread & came across this.....

Not negating what you're saying, as you have experienced it personally, but I'm curious how the heat of the exhaust could possibly allow enough moisture to condense or get trapped under the heat-wrap, without being boiled or evaporated out the next time the exhaust gets up to temperature?

Wouldn't any moisture just get fizzled up?

Not everything will be cooler, the turbo internals and the down pipe should be hotter - that's what I was referring to needing to be engineered for the extra heat

Sorry to disagree Martin but none of the internals can actually get hotter than the original heat source i.e. the exhaust gas. Wrapping, blankets, coating can't make internal items hotter than they already are as the heat, which is at peak temperature, radiates out from the internal source. They may keep the outside surface hotter than standard in some instances, but we are talking about metal surfaces that are designed to take the maximum temperature of the internal heat on it's way through them to the outside world.

What happens with effective thermal insulation is that the exhaust gas retains more of it's heat (doesn't lose as much to the metal surface then outside world), which helps it flow better & actually extract more of the heat from the combustion chamber & exhaust manifold etc so that in practice the external surfaces run slightly cooler than standard.

With respect to wrapping it does retain moisture over time & will rust through pipes eventually.
