There was a lot of talk about the aquamist-system a while ago, but it has gone all quiet again.

 

So, I was wondering if there's anyone here that has this sytem actually fitted in a Z ?

Any good/bad experiences ?

I know a few people with it - but not one with a Z .

 

Personally I like the idea to start with but when you look into the details of the system it arroses some questions that i have not been able to answer to the extent i would purchase the unit or recommend it.

 

A lot of the guys that i know run it on Supras and Sevesn and don use it for in cylinder injecotion they use it to cool the intake charge which kinda defeats the object.

 

I'll keep looking into it - but i would recommend you go into looking at bigger IC's and even the IC ducting to improve intake cooling as much as you can first... unless you have done all that already in which case I would sonner have N20 :)

 

Z ya

Hmmmm...... That gets me thinking - group buy on N2O systems anybody????

I think that the Scoobey Doo idea was pretty neat, button on the dash which sprays water onto the IC during boost. Was this just a gimmick like the exhaust note button on the GTO? Or did it actually have a + effect?

 

It must have done something good otherwise they wouldn't have put it on in the 1st place I suppose...thoughts?

I used aquamist on a heavily modded escort turbo and it allowed me to wind up the boost quite a bit more with no signs of detonation. Setting up a little pump to spray water on the intercoolers is a very cheap and easy mod what might be worth doing.

I have tried NOS on my Z and it does not like it very much so im taking it off. If you want Nos to run well on one of these cars I would suggest you buy a fully progressive controller for it so you can delay the gas a little to allow the fuel to get through the solenoid and pipe or you will detonate.This adds quite a bit more money to your system and would probably be better put towards bigger turbos or something.

If anyone does have NOS and needs any re-fills I have a full size cylinder of the stuff here that needs using up.

Paul, tell me more about your NOs. Who fitted it, how was it fitted and what's a progressive controller?

 

There was a guy (Malcolm) at North Weald who fitted his himself and it seemed to work well. He posted some impressive times in the 12's.

 

I also see that on their web site JWT have a set up for the 300 to run NOS, and go in to all sorts of technical details.

I would only advice a recommended NOS kit.

 

For TT's i would say go with bigger turbos and then get the anit lag NOS if you really want it.

 

If you get a Dry shot off NOS with Traction controll you will blow the shit out of your engine as you will lean out to shit.

 

It is good for NA's tho...

 

Z ya

Still at work and pissed as hell !

Well...about the the intercooler spraying:

It was done on Z's by a few guys on the Aussie-forum..

There's also a writeup on the installation of it: http://www4.bs.monash.edu.au/oz32/Tech/icspray1.htm

 

They don't prove/show if it has any positive effect though.

I personally doubt if it will have much effect at all with the temperatures that we generally have here in the UK/Northern-Europe.

Oh..and for those that are not familiar with the aquamist-system...

Don't confuse it with intercooler-spraying.

 

The Aquamist-system actually sprays a thin *mist* of water into the intake-manifold/engine to cool the air.

 

The intercooler-spraying just sprays water on the intercoolers.

 

-Eric

 

i remember reading the articles and findings about ic spraying, and basically, you need to spray before you boost, so you need a pre-emptive system really....

 

as by the time you boost, you already need cold i/c's....

 

 

 

Time for a showdown Craig!!!

 

Simple physics m8. The greater the temperature difference between hot and cold, the more heat transfer per second! Think of the temperature as volts across a resistor - the greater the voltage dropped, the greater the current. Therefore the water cooling would have more effect AFTER the turbos.

Will I get barred from the forum now for trying to be too clever?

 

Henri - any questions???

lol

 

Only joking Henri!

My Nitrous was from Highpower Nitrous in Doncaster, I know their stuff is good cos Ive tried it on cars and bikes. I think that a Z with a boost upgrade is running near the limits for detonation anyway thats why its prone to Knocking when you hit the gas. It would probably work well on N/A version.

A progressive controller allows you to delay the nitrous and/or fuel ,and bring in the extra power gradually to avoid wheelspin (which doesn't feel so good if your on a bike).

I think the idea of watersprays on the IC's would work, after all its the same principal as a chargecooler only cheaper :-)

Water does dissapate heat better than air.

The ideal intake temp at the plenum is 40 degrees so I beleive and at around 1 bar of boost temperatures can reach up to 100 so cooling off the IC's must do some good. A simple microswitch to switch them on when you hit 3/4 throttle will make sure they are getting a good soaking when you come onto full boost.

Paul

 

erm.. andy.. want to read what i wrote again ?

 

if your i/c's are warm (read heatsoaked from lack of external airflow) then when you generate boost (on the move) you have to cool the i/c's down a bit first, before they start cooling the air going through the i/c's internally

 

therefore, to get the most from the i/c's and an external spray system, it would be better to spray the i/c's before you start to boost, so that the i/c's do not have to cool down externally before they start to cool the internal air down

 

you follow that sonny jim ? ;)

 

Oh I see - why didn't you word it better then!!!!! ;)

 

OK, so we're both right!

 

Andy

 

the cheapest and most effective way to get water into your intercoolers is to ride your car in the rain lol.

therefore you have it in the uk 364 days a year.

so whats the point of fitting it.

ps (one day of sunny weather is taken into account)

 

cant u just put a window washer motar near the ic sounds a cheap easy way only cost u about £15 including motar wire and switch this is probably a stupid idea but it might work

A Cyber spray kit is a cheap and worthwhile mod on any turbo motor running mods on poor intercoolers. Nissan, until Skylines came out, never put decent intercoolers on their cars, infact some had none. Everone knows the Z ones are a bit small for the job, check out all the Renault 5s and Scoobies, Cyber sprays fitted and some come from the factory like that. I know SE have done this to at least 2 zeds. Using the headlight washer bottle for water, a 50 degree sensor on intercooler pipe and the wiring not to sure about. It has the same effect as driving your motor on very cold winter morning. Anyone like to make up the kit, then put me down for one, definately. Smithy, i.o.m

 

i know i will probably have a contract put out on me by johnny and the purists out there now but has anybody thought of doing a frankenstein and using a couple of rs500 intercoolers under there instead a quater of the price just as good if not better and although larger im sure they'd fit and the hose connection is still the same size

 

Tooley, fitting a couple of those babies would probably cause serious lag, although not very large their cores are designed to cool air sufficient enough for around 500 bhp if not more, fitting I/C that are tooooo big is a common mistake,our I/C are small yes, but the cores are not of any great thickness or quality and that's what lets them down. Unless you were going big in power terms using a Cyber spray kit would be ideal, cost would only be around £50.00 but then a days labour on top. If someone helps me locate a couple of spare standard Z I/C i'm looking to have apair made up that are only a couple of inches bigger all round, but fitted with WRC cores and possibly displacement plates if the fabricator thinks neccessary, his work is some of best i've ever seen anywhere.

I'm considering getting it installed.
