hi

im pretty sure the IC spray on the newage cars is useless , on my brothers jdm car on auto, it has never even come on..

i know people benefit from putting liquid c02 onto the IC etc.

has anyone managed to use the current setup but replaced it with something more worthwhile? i.e. instead of water something else?

or is the only method to remove it and replace with a liquid cryogen kit?

pics of your mods /setups would be good.

cheers

 

If you want to lower charge temps there's always aquamist

haha i agree i press the button now and again makes a noise but seems to make no difference at all to the car!

 

ive heard in another thread that the standard ECU can cope very well with temperature differences so of if you use N2O or CO2 to cool the IC, (even unmapped) you'll get more power.

is there no changes that can be done to the current system to make it better instead of replacing it?

 

I don't know how it's mapped on the newage cars, but auto spray on the classics requires a coolant temp in excess of 75 celsius, engine speed in excess of 3800rpm, road speed in excess of 96km/h, MAP (repeat, MAP) in excess of 1.14 bar and inlet air temperature in excess of 28 degrees celsius before it will activate.

If the activation parameters are similar on the newage, that would probably explain why your brother doesn't see it very often. It's rare in this country to see an inlet air temp in excess of 28 degrees, for example.

If you know how it's easy to alter the control strategy so it functions more (or more intelligently). As I run charge air temp as well as inlet air temp sensing, mine is programmed to switch on when the delta between IAT and CAT exceeds a preset value, rather than on the basis of an absolute air temp, for example.

All that said, the ability of water spray to materially affect the charge temp is relatively limited.

 

Do a 50/50 with water and meth then you should definitely feel a difference

 

Mine feeds the washers now, as I needed the space upfront for a catch can.

And don't pour "meth" over your engine bay, please..... unless you carry an extinguisher !

Having a manual button only is pants !

P.S. The AIT sensor is in the MAF housing, so it won't really "know" what's going on, IMHO.

 

It knows what the inlet air temp is, which is all it needs to do most of the temp compensated stuff on the standard ECUs. However, you're right in that the standard setup does not provide a complete enough picture as one might like, in this area in particular.

50/50 methanol and water in the aquamist would be better.

Shaun

 

what would this do? better cooling than just water?

lol as for water/meth injection, seems quite pricey to setup/install..

maybe for drags i should get a c02 fire extinguisher and spray the ic before each run lol

 

That's no help if pouring liquid NO2 onto the IC in my HO...



dunx

 

ive heard the water/meth combo does work well, you spray it internally though dont you

 

It makes virtually bugger all difference.

If you really want cooler charge temps get a front mount

 

Good point Duncan

Banny

 

lol i i know a front mount would be the best way but i dont wanna go front mount as i get enough people trying to race me as it is..

i think my mate still has the cryogen kit he bought, but never fitted, if he does i think i might give the liquid c02 kit a go and remove the IC Spray.

 

Easiest way to get lower charge temps as Shaun says above, would be with an aquamist 1s water injection with an aquamist dds 3 gauge for monitoring.

Then you can run 50/50 mix with water and methanol, with a boot mounted tank.

Banny

 

i dont really know anything about water injection or who can set that up for me, i'll have a look into that aswell

cheers

 

Andy @ Richard Henry was willing to install mine, then just get Duncan to map for it job done and a nice increase in power too

Banny

 

cheers banny

any links to the kit i should be looking at? or can richard henry get hold of them?

 

This is the kit:

http://www.aquamist.co.uk/cp/sys1/sys1a.html

and monitoring gauge

http://www.aquamist.co.uk/press/DDS3-v8-web.pdf

He wont be able to supply them afaik, you could get a spec c boot mounted water tank for the o.e look.

Banny

 

thanks banny

 

See bottom of post #5.

 

indeed lol

I did actually measure the effectiveness of the ic spray when i still had the tmic and charge temp gauge at the throttle body and the difference it made was about 1C (if that). Be quicker saving the 5kgs+ in weight.

 

I've got a Spec C 12 litre tank of 50/50 meth and water in the boot with an aquamist system mapped by Bob Rawle.........makes for interesting pub talk (Foke Wolf 190's used methanol injection) but very expensive for each BHP gained though. LOL

Shaun

 

I run both a W/M injection system and waterspray over the tmic. The injection is tapped into the underside of the intercooler at the outlet into the throttlebody and progressively sprays water/meth into the air charge. The kit was about £500 but the installation costs were nearly as much. It does work and is reliable but as Shaun says it's a low return on bhp but it does make the engine safer.
The waterspray is limited in its use. I cannot see the point of spraying tepid water or water/meth up onto the intercooler, however I target my usage with very cold water i.e 3-4c and when ambient temps are 20+ it does make a difference.

And we used nitrous oxide, damn those Germans....

Why does Subaru go to all the bother of fitting them then

and even take it a little further with auto option and 12ltr tank

 

Because any reduction in charge temps, be it only a couple of degrees is helpful in improving charge density and reducing the possibility of det..as TESCO says every little help LOL

Water has a high latent heat of evaporation and if air is flowing over the intercooler then the energy for this will be taken from the intercooler...in hot and dry climates this would be quite helpful but as britain has pretty much a cool, and lets not deny it, wet and dreary weather the effect will be marginal LOL

Shaun

 

Two laps on the track - with and without waterspray.

Air temp 30 C that day !
