Pack of ice on turbo/intake mani = better 1/4?

[OfnaRcR]

I've always seen this done on cars at the strip. Question is, would it make much of a diff on my car?
Only modest mods:
2.5 in hardpipes
Spearco replica intercooler
3 in exhaust with stock elbow and 3 in DP
shimmed wastegate (not sure how much, but it peggs the stock guage.)
Driftmotion rebuilt motor with about 6k

And just for fun, could anyone guess what kind of time i could expect?

Given the velocity the air is travelling at the minute you're past idle I don't imagine it helping at all.

id say you run a 16 maby a 14 if your lucky.

You're probably right. You always were better at estimating this kind of thing.

My mercedes mechanic from 10 years ago used to race in the 60's and he said a lot of the racers back then would use Dry ice in their air cleaners, they would have to have a specially fabbed tray for it though. It was placed directly inside the air cleaner by the air horn so it would be drawn in with the intake air but not impede the normal flow.
Im not sure how you could get that to work unless you had a box with the dry ice mounted at the initial intake in front of the air cleaner. Dry ice lasts for hours and would work much better than normal ice.
Let us know if you use it and the results.

I've heard of a few people icing down their intakes and intercoolers/piping. It probably only shave a tenth or 2 off your time. If that.

if you can find a way to place a block of dry-ice by your intercooler

ive always thought about buying those 1" thick blocks of dry-ice
since it CO2 anyways ands thats the same they use for the IC spraybars
only the one in spray bar comes in gas state
and the dry-ice is in solid state

so the idea of the spraybar is to cool-off fins of the intercooler so it has a better change of cooling the air coming from the turbo
although it only does it when its activated, and a really hot day, i can only imagine how much you need to actually get the IC cooler

but with the dry-ice if kept in constant contact with the intercooler will provide constant cooling

i dont know, anybody think this idea could work?

^^^I'd rather use a couple peltier junctions. Cheap refridgeration which doesn't require a refil. Google it.

[Supra2NR]

^^ i googled it, sounds like a decent idea

got a question tho? how much cooling capacity does it have?

[cre]

Depends on the pelt. I've seen a pelt turn a bowl of steaming water into a block of ice in a couple seconds before.

Peltier junctions are not very efficient though. Using a couple would probably require swapping in a lager GM alternator... not too big of a deal, they're not much larger than ours and they're pretty inexpensive.

Pelts also have to be cooled. The easy way of handling this would be to use a water cooling block for a PC and plumb it in with the cooling system. Wouldn't take much just a length of 1/2" hose... that or add a heatsink, but then you have to make sure the heat sink gets enough airflow.


To do somethinig like this and actually get a decent return out of it you would need to:
Upgrade your alternator
Insulate the intake piping (heat wrap or ceramic coating)
Make sure the pelts are well cooled


A setup like this would be FAR more effective than just a bag of ice set on the intake, but it's not the simplest thing to set up. A water injection setup may yield similar gains without the added power consumption.
