Anyone using a barrel air-to-water intercooler?

http://www.pwr-performance.com/intercooler.htm

At the bottom of the page there's a kit for $935 that has the 6" barrel, heat exchanger, electric pump, etc.

I know the ST205 air-to-water IC is ideal, but considering the limited space in our engine bay, this seems like the perfect alternative. The ST205 piping has to be modified, and I'd hate to track down a replacement Toyota electric pump if it fails.

This kit would offer the least mount of piping with a straight shot from the turbo outlet to the TB inlet. Also, since the heat exchanger is far smaller than the ST205 heat exchanger, you could mount the exchanger in the stock intercooler's location.

Anyone who's using a custom, NON ST205 w2a IC please chime in.

"I'd hate to track down a replacement Toyota electric pump if it fails"

I had no intention of using a toyota pump You can buy an uprated lotus esprite one in the US for $125 - this is what I actually imported to the UK for mine and we got the St205 celica's over here anyway

Water-to-Air Intercoolers are no longer allowed in the NHRA SP/RWD class (as of this year) ... unless they are an OEM unit.

Do you know the reasons for this new rule?

 

[JekylandHyde]

No clue ... but they did say you can have nitrous or CO2 in there instead of water and that IS okay ... BUT it counts as a power adder so you have more of a weight penalty.

are you sure they are not talking about water sprayers and not air to water intercoolers. Many drag cars run air to water, i dont see this happening, if so that sucks

I don't really care bout those kind of rules. I am a street car guy that runs at the track every once in a while. I have the big PWR intercooler. It has worked great. It has a little bit more of a pressure drop than the Spearco that is close to the equivalent, but I get very consistent intake temps with no heat soak. It would be cheaper to piece your own kit together as well. I mounted my exchanger in the front. I call it my front mount interfooler... ha ha. Anyway, It seems to be a good product.

morons....all I gotta say...like a2w is the same a Nirous or C02...fokkers.

perfect solution imo would be a top-mount tube/fin type core mounted on the left side of the bay. main reason why: it's AWAY from the downpipe. the border racing intercooler kit comes to mind.

NHRA Rules Changes for 2005

Engine
Intercooler must be air to air only. CO2 or NOS is permitted as a cooling medium in place of water in liquid intercooler, but will count as a second power adder; i.e. if CO2 or NOS is used as an intercooler medium, NOS may NOT be used in the engine. OEM liquid intercooler permitted only if OEM engine and OEM power adder is used.

is that the same as nopi, is that your class?

 

[tilma800]

Which pumps will work for us and are reliable and relative cheap.
Where can I source the Lotus one?

 

[JekylandHyde]

MR2 2NER, NOPI has different classes and rules. They allow much more.

 

[Tomg]

SO the rule say, if you use water in the a2w ic, it is fine!?!?

"OEM liquid intercooler permitted only if OEM engine and OEM power adder is used"

Ambigious rule realy.....can mean anything.

[Tomg]

It sounds they will allow a2w as long as you use water as the cooling medium. It is only when you use c02 or NOS as a cooling medium, it will be counted as a power adder....now why anyone will do that when they can use ice in the resorvoir, is beyond me...

[JekylandHyde]

Tom , they mean you can use water-to-air if it is OEM ... if you have a stock water-to-air (like the celicas have).

 

[JMcDonald]

Wow Jekyl that is a wierd rule! It wouldnt be so bad however if MR2s didnt have such an obvious advantage lol (engine being where it is). But I still think that making money less of an object in lower classes (no hinting or anything J&K ) makes it more fun and more about driving and making the most out of what you have, instead of who has the most money.
