Thoughts on Intercooler sprayer

[jonlax]

I pulled some things out of storage from before i joined the military and found 3 of my sneaky pete nos bottles. I originally used them on my 1991 turbo II RX7 for an intercooler sprayer.

I purchaced new and found a cyro style unit to mount to my front mount. worked great when i had to sit at english town and ATCO raceway on race days. Anyway long story short i am looking to adapt it to my top mount unit and eventually move it to my front mount whenever i get some cash for a new core.

Has anyone ran a system such as this with any results? Also anyone know when the NOS bottles need to be pressure tested again? They are 7 years old now and i can't find any thing on how long they are good for....

Also thoughts on changing to Co2 over the No2?

Seems No2 is colder than the Co2 but cost wise the Co2 is about 5 or so a tank.

Well it's been talked about before, so I would suggest searching. More people tend to spray deionized water on the intercooler than nos though.

Very true, thus the reason i used No2. I see alot of people complain saying that the No2 is uneffective compaired to meth and water sprayed on the I/C.

Everyone knows water or meth pulles away latent heat but the possibility of water on the track isn't good. Also the effencenty is stated with meth/water being cheaper and No2 not doing much.

Here is my findings when i had my front mount on my RX7. My intake charge was up to 20 degrees colder. Now i never used meth/water spayed on the I/C which would lower it but thats depended on evaporation and we all know summer months it wont happen.

So i come to this.....Does anyone have any logs or evidence of a gain over the dreaded heat soak?

[ScarMS3]

If the ic is hot and it is a fine mist I would assume most would evaporate. But +1 for the hero comment.

[shadesofgray19]

Meth/water sprayed in the motor is better, problem solved.

[86AmishMs3]

Of course there will be a gain over heat soaked engine. You already have the equipment, just do it and post up pics and how to.

[LuczOr]

I would say water, its all going to evaporate... Unless you are spraying it through a garden hose nozzle. Even if it doesn't evaporate, the valve cover is under the TMIC, and that bitch is hot as hell too. As a matter of fact, everything under the TMIC is hot as hell.

[Mistersix]

I would try co2 simply because its cheaper. You may find the need to use much of it for a worthwhile effect. The IC's right on top the motor and will probably start heat soaking immediately after you spray.

[86AmishMs3]

I would want one just when i'm at the drag strip. when you're moving everything is fine, but when you are sitting there is no air to help cool. A sprayer would help to cool the intercooler before a run. During run it would keep it super cold. I would do it if i had the money

But if your not moving how would the spray move over the intercooler? One would need some pressure to force the gas down, no?

When no2 or co2 comes out it comes out as a solid and it's also so cold it causes water to condensate and freeze. So it's not like it instantly evaporates

What i'm saying is air needs to flow over the intercooler in order for it to exchange heat. So if if your staging for a race whatever you spray would HAVE to move threw the bars and fins to chill them.

Hence you would need the gas to spray at some pressure in order to do so. Its not like the intercooler is wide open on the other side its kinda blocked. Without air flowing under the car to create a low pressure zone, there's now vacuum to help air flow in the ducting, over the IC and down around the engine and out.

This is why i wonder, if spraying an IC thats essentially in a tube with no air flowing threw it, would even be effective.

I think the air flow dynamics need to be addressed before deciding on what gas to use.

[ScarMS3]

co2 is a gas, unless its frozen...its not going to come out solid. ie dry ice.

[brantms3]

C02 for sure if you really want to try it . I thought about it after i saw some rednecks here in austin icing up there intercoolers before they shut the motors off on a bunch of 1JZ powered toyota sedan turds. but what was funny is that there cars actually idled better and ran better after each race on the streets. Test your theory withsome duster turned upside down or something. then if it shows any real advantage .. make up something permanent

[jonlax]

Well looks like I will be staying away from the Co2 just for the fact Its not as cold as No2 and the amount of Co2 needed is doubled.


Maybe the next nator day ill rig it up.

[Islandromeo]

Iv seen this method used very efficiently here in Hawaii where its hot and humid as hell I'd say try it but try to see if you could some how protect the motor from direct spray maby a deflecting under the TMIC

[jonlax]

If you put a deflector on the top mount you will loose any cooling it offers. A low pressure is below it which helps airflow.

I don't think a deflector would be needed anyway.

I would like to add something, albeit not spray bar related.
While waiting in the staging lanes with my 88 RX7 TII, I would ice the top mount and leave ice on it when going down the track. Times dropped from around 14s to 13.465 with no other changes. All I had was intake and exhaust...and wicked boost creep.

Funny story, the track official at the starting lights wasn't pleased when a few ice cubes slipped out of my hood scoop after warming up the tires.

Now I'm driving an '06 MS6 GT (w/o Nav). Currently stock with about 125k or so. Got it Dec 2015.

I guess I need to go back and read the rules again, I'm sure they've changed in the more than 5 yrs I've been a member.

As far as this forum being unhelpful, it's the only one I use. After a while you will be able to see that it has the right info, best info, etc.

Group hug time :-)

[faeker]

stfu. you're just post whoring. this thread has been dead for a long time. I'd take you back down to 0 posts instead of banning you, and just when you're about to hit 100, do it again.

[MS3Shadow]

I didn't threaten to ban you, i was merely informing you of the rules in case you forgotten,

You tried to sell something while under 100 posts earlier. I could've banned you then.

I put dis on my core..keeps it cold as...well...ice

Ok continue. My work is done here

[SofaKingAwesome]

Fuck that guy, banninated.

I told this clown to watch the line he was walking. Guess his ass didn't listen.

[PrematureApex]

I can't see all of his posts, but he probably didn't think that heeding advice from the type of mouthbreather who calls people "faggot fucks" (which is apparently not against the rules?) was a good idea. Can't say I blame him.

RIP20boxer...

Peter, commenting in here pretending to be another account is about the oldest trick in the book. And now you get permabanned for creating a second account to circumvent your first ban.

[faeker]

fuck off with your one post faggot. someone ban this dupe account.

[faeker]

the only people who get offended are faggots themselves. suck a dick dupe.

Sounds like @PrematureApex; came too early.

You can be banned for "Quantity" posts as it's stated in the rules.

This is twice in two weeks you have threatened to ban me. And this time it's because you poked your face into a thread I commented on. Sorry this forum doesn't have any good content that's recent. You post asking a question, you get yelled at to search. You search and comment on a thread, you get a trigger happy mod picking a fight. You obviously have a TON of time on your hands. You obviously couldn't let my lighthearted comment about "quantity over quality" go without getting your panties in a bunch. I paid to be a member on this forum to gain access to a community of people who can help. You are the antithesis of that. Go a head and ban me. Worst $25 I have ever spent.

You read the rules, you knew the rules, you wilfully and intentionally breached the rules. Then you tried to rub it in our faces. This isn't going to end well for you.
