I wonder if someone could help me out. I have an Alta Version 1 Intercooler and it doesn't seem to be doing the job Properly. If I was going to spend some more money on an Intercooler which one out of the subject line is going to be the best one to go for?

Thanks in advance

 

I love my GRS chargecooler (water to air) - since the fuelling has been sorted, IAT don't go above 38 dec C, and the car feel 'clean and crisp' at all times, even moving through traffic.

Far better than an A2A in my opinion - those that whine about heat soat, track use etc are unlikely to have had/tried/tested both. I've have three A2As and now the chargecooler - there's no comparison really.

Cheers,

Henry

 

I have the Madness water to air and really like it(got a really good deal here on NAM marketplace, 1/2 price used). My MCS has consitant power now. I have also had the Alta V1 and V2(DFIC) which had a lot of heat soak in stop and go traffic.

 

From what I've read and come to understand it does depend on your application. Track needs are different from daily driving and even then daily drivers differ. Those that are stuck in bumper to bumper traffic often have a different need then those that have commutes that offer more open road.

What is is that you are experiencing?

What otehr types of mods do you have?

This is more holistic approach then asking whats best, as whats best for me may be different then you since our overall situations may differ.

 

Thanks,
I live in Australia where the climate is pretty hot. I have a 15% S/C pulley and a 3% Crank Pulley along with a whole heap of other mods. I have just had my Unichip custom tuned on the dyno and they have had to take a whole bunch of timing out because the IAT's are so hot. I'm talking you can't put your hand on the intercooler for about 5 mins as it is really hot. You could almost cook off it. Plus the cars is running 17 pound of boost!! So I am going to drop back to just the 15% S/C and stock size Crank pulley. I really just want to get the temps down so it can be tuned better. I am thinking of just setting up a whole bunch of water sprayers triggered by the Unichip to come on at boost and at Idle just to keep the temps down. The one at idle would only come on for about 10 seconds once you back off the pedal.

 

Glad to see you going back to a 15%
This is exactly the problem with running so much boost through an Eaton.

 

I have had a few different air to air intercoolers and I have had the best luck with my Mini Madness air to water. I dyno pulls are almost the same time after time. With air/air I was losing 20whp after each pull even with fans and spaying everthing down with water. I'm a believer of the air/water for the M45 Eaton.

Hey revolution,

Thanks for your input, it is good for a vendor to help out on this sort of problem and get advice off as well. What sort of intercooler would you recomend? From what I am hearing this water to Air sounds like it is the way to go, especially in our climate. Any other vendors that would like to add to this would be great. But I really would like to see numbers on what each one does. I now know that the Alta Classic or any like this for that matter are not the efficient as the air blows through the intercooler straight onto the top of the engine. When idling the heat just radiats off the engine and this intercooler just soaks it up like a rag soaking up water.

 

Testing IC's on a dyno doesn't work. You really need to hook gauges to the them and log the data then drive on the track or street to see whats really going. On the Dyno there is not the airflow needed for an IC to work properly, even with fans on them.

 

We are testing a Laminova core on the track/street... so far so good
we will also be making a more compact version soon.... too many projects

 

Laminova Please explain, is this better than a water to Air? or how does it work?

 

it's a water to air core
it's known as the most efficient core type

 

How much will you be selling it for? What other makers use this type of core?

 

we are in the process of designing a top of the line system for very high hp cars. It's in the developmental stage at this point so there is no pricing. We hope to get something around Christmas if everything works out.

 

Witht the water pump, how do you normally hook them up. Is it via a relay of some sort or is it just hooked up so when you start the car the pump is pumping?

 

Might be a stupid question or not as I don't know much about them. How does the Water to Air intercooler work?

general information on water to air intercoolers


i am pretty interested in a water to air intercooler/exchanger. i guess i'll wait to see what Rev. Mini cooks up.

 

Make sure your hood to diverter seal is sealing,(take a flashlight and look into your scoop with the hood closed) if you have a gap the cooling air will go on by and not through the IC. Water sprays will only work well in low humidity high heat situations unless you have cold water and alot of it. Now high pressure water injection is another matter. It uses much less water and you will be able to get your timing back.

 

I am not sure if the water to air is better in all conditions but in most of them is!!!

You have much more constant temperature comparsion to AA version.

If you have AA you don't have any cooling at start. Even at lower speed that could not work great.
With Water to Air you have full cooling at start, because the water circulate all the time. It is true water geting warmer, but look you cannot warm 5 liters of water in few seconds.
My KMT Water to Air works great. I won't go back to AA setup. I have two radiators to cooling water and I do not have any bad words about it. This sistem have about 5 liters of water and the pump circulate about 23 liters of water per minute.

 

Does anyone have pics so I can see how they are hooked up. Also how is the water pump hooked up?

 

I will do it just for you a few pic today.

 

I await your post with great anticipation.

 

Everybody loves Pics!

 

Hmm last time I got my car Dynoed I was within 2HP on all 3 pulls, I wounder if I was already heat soaked?

 

It doesn't sound like it. I was going from 227whp down to 201whp down to 180whp with an air/air.

BTW how do you like Fresno, I'm looking at buying a business up there.
