RX8 Intercooler
 

Hi guyz.!

Juz wondering if you guys have any workshop to recommend to change my intercooler. Thinking of changing to a bigger one

Hello
Try GarageR. I get my parts from there. Their understanding of the 8 is great and their staff are friendly and helpful. Happy shopping...

Ok man... but heard their quite ex although their workmanship is great and all ..
but i dont think itz going to be easy on the pocket

Not many people here on our island knows much abt the ROTARY engine. SO, sometime got no choice to pay a little ..rather to have headache later, end up ..paying more :D

Go to GR. If u want to splash on something better, why be penny foolish? Might as well start a meaningful relationship as I am sure this will not be the only thing u are changing rite? :)

intercooler??!!

+1

wtf?

Yeah I'm with them ^^^

Intercooler...please go into more details

I am sure he meant radiator....

Yeah... i meant intercooler...

Radiators are not as efficient as intercoolers therefore i am trying to get someone to do the change. not sure if it will work but itz worth a try.

yeah.. i understand the situation :) itz definitely better to get someone who knows whats he's doing rather than someone who doesnt.

Wow, if u manage to get it change, tell us how good is it and wat is the damage like on our pocket :D
COz I would be keen too (if the damage to the pocket is not too serious :p ) ....

Oh my lord..no, no, no, no...please don't. :(

(sigh).


It's not worth a try...save your time and $ please.

Why not???
I find itz a much better system than the current water cooled rotaries that we have. If it works, it will be a much better enhancement and will prolong engine lifespan.

I am currently looking at a HKS intercooler made for the RX7, Will talk to my mech about it .

Well, do let us know if it works....good luck!

:confused: How would an inter-cooler cool the engine better than a radiator?

Why not get a better radiator, and keep the inter-cooler for your turbo kit?

I'm as confused as you are. :confused:

Sounds like a 'ricer-mod' to show off a big shiny intercooler.
I'm not sure whether it is technically possible. :confused:

BTW, upgrading the radiator and adding additional thermo fans is a better idea IMO.

Easier and cheaper to do as well with less headaches, then again, no big shiny intercooler poking out at the front......... :rolleyes:

More questions...my understanding of an intercooler is to cool the compressed air created by turbochargers. So how would a stock RX-8 possibly benefit from this?

It won't benefit - could it be that what the guy wants to do is say he has an 'intercooled' RX8, without the trouble of acutally building a turbo/sc system for the car? I dunno. :( I wish any benefits of the project could be explained to me.


But - it's his money to waste...after he's done, he can pick up one of these and be all set :)

Lol

Are you suggesting the use of intercooler instead of radiator? So, you will not be using water to cool your engine? Instead, air cool it with an intercooler? What happens when your 8 is sitting idle, no air blowing your shiny intercooler? And did you know that air gets hotter than water? Water is used because it transfers heat away from the engine better. An intercooler is used to cool down the air blown by a charger. Using the word cool in the intercooler doesn't really mean refrigerator cool, just cooler than without an intercooler ok? You will end up killing your engine replacing a radiator with an intercooler.

If you are just making an excuse to get that shiny intercooler up your front bumper, then get it installed there without a function, just don't replace your intercooler. I think this whole idea is just trying to justify a ricer mod, period.

Just save up your money for the real Turbocharger with intercooler instead of using that money for installing a ricer mod and payment for a damaged engine.

Pardon my ignorance but i assumed that the intercooler would work in replacement of the radiator.

It's cool dude. If you want better cooling for your engine, I suggest you look up Redline Water Wetter. Redline's website explains a lot about the benefits of it. Living in Asia, you wouldn't have a problem not putting anti-freeze in your radiator.

:p ........best thing I've heard all day.

no it wouldnt work.....
when i first read this thread, i was like... WTF :confused: :eek:
this would've top the N/A BOV mod... hahahaaa....

The radiator cools the engine. The intercooler cools the intake air. Different function.

Air is denser when it is cooled(at high temperature, the air molecules have faster speed and thus have more energy to bounce off one another and thus would be spaced further apart and thus there will be less air molecules per unit volume). What the intercooler does is to make the air denser so that there will be more oxygen molecules for combustion. But it does not cool the engine as it is not designed for it. If you replace the radiator with the intercooler, you will have denser air but hotter engine(I would say the benefit would be minimal as the high engine temperature would have offset any benefit of the intercooler). Without any effective cooling for the engine, it would overheat pretty soon and you would soon be looking for replacement.

WOW!
now thats a proper explanation that can be understood by a newbie like me, without having all the technical words. Good job Manwe!

Intercooler injects cool moist-liquidform(vapor like) air into turbo turbine. The turbine will then spinned the air from exhaust into intake. That converts moist-liquidform into air like particles. The cool air will then keep the engine cool, therefore less friction between pistion and cylinder body. This process will improve boost of RPM....

If you inject intercooler directly into your engine, it is like pushing vapor instead of cool-dry air into your engine. Imagine, water at the bottom of your oil-pan and mixed with oil when engine runs.... holy crap.... gonna be in deep trouble.... lots of $$$$ need to be invested.

I think you're getting confused with water injection. A regular intercooler doesn't inject anything. It just cools the air and makes it denser which like Manwe pointed out, provides more oxygen molecules for better combustion (with an appropriate increase in fuel, of coz). Manwe, still remember studying about those old turbo jet engines with water injection??

Wow, I didn't know some people do not understand what the Intercooler really does. I thought it was the most straight-forward part of boosting.

Yea... also remember all the piston engine stuff... tdc, bdc, displacement. Then still got gas turbine, supercharger and turbo charger etc etc. Also vaguely remember engine layout such as cylinder, opposing etc etc. But cannot remember where....think is in post or izzit pre?

Anyway, an increase in air molecules without any associated increase in fuel would also increase power by leaning the mixture with slight disadvantage of hotter exhaust(unburnt fuel would evaporate and cools) and that though boost power slightly would actually shorten the lifespan of your car. But considering the fact the the lifespan of the car is limited by the COE, I don't think it is a heavy penalty.

i know this is old but...
 

None of you understood what the guy wanted to do, he thought that an intercooler was ok as a direct replacement of the rediator, not with air cooling but like to hook up the water hoses to the intercooler, and the guy talking about injected intercooling with pistons and what not, was clearly being sarcastic, amusing thread tho lol

If you don't know, intercoolers are what you run the air coming through a turbo through to cool it which helps boost HP due to the cold air

Wtf
