has anyone heard of the wavy intercooler mod?
supposedly you just use a press to make waves into the intercooler.. effectively causing turbulence in the airflow which effectively decreases air intake temps by a whole lot more than a straight intercooler..

here is a modified greddy intercooler... from what i hear it doesn't work with cheap ebay junk intercoolers.. because all they do is snap in lots of places.. some people suggest that you stick the chinamen intercoolers into an oven to get hot before even trying to do the wavy mod on em...


the theory is simple.. that the air will have more contact time with the fins of the intercooler thereby decreasing the air temps by alot!




theres some dyno graphs out there and also ive heard this from more than one person.. theres also someone testing with a temp sensor on standard intercooler vs wavey and the wavy intercooler kicks the standard intercooler all across the board..

more temp drop
responds better to nitrous spray onto the ic

the only downside to the wavy intercooler mod is that it causes a little bit more psi drop.. but the considerably cooler air intake temps make up for that in hp.. the psi drop can be made up for with a mbc anyways

It's true.

All about thermal transfer, the same as your radiator, yes you can run without a thermostat and your car will be fine, but the added resistance in the coolant line directly after the radiator will help with transferring the heat into the radiator and out into the air.

As opposed to carrying it back into the block, though a mean coolant temp is usually established.

The temperature difference in water is negligible because it's got such a high latent heat capacity, but with air, that's a different story.

yeah i've read about this a while back, when the air goes into the intercool it bounces at the 1st wave causing it to bounce and not just go through the fins, but it has a longer time in there.....longer time in the intercooler, the more time to cool the air. the cooler the ait, the most HP gain.

MacONE

but you can't have too much wave....it has to be a optimum wave distance, or you'll cause restriction.. so dont try to wave your own intercooler, buy a real one!

I have successfully waved my own ICs for years.

isquishplantano, expect to hear from my lawyer first thing Monday morning regarding your revealing my proprietary race secrets on a public forum.

MacONE

sorry joseph this technique/technology has been out for years!

I followed the directions in this thread to the letter, and the results are amazing! I was able to run a leaner mixture and add more timing, car runs great.

ohh man dose any one make these?
were can i get one?

This is amazing. Wish I knew about this before I put my intercooler on my car, I guess I could always take a sledge to the bottom and try to do the same thing essentially.

this picture has 'good story' written all over it.

PhilStubbs

there isnt much of a story really. a friend of mine bought a greddy kit form a wrecked car. we used most of the stuff originally except the intercooler. then he sold the setup and started a new one. we threw that on his car for the new setup to see if it would work and it worked just fine. we ran 10psi with no leaks and made decent power for a b16 with 8:1 compression. im not here condoning that thing cause it is hideous, but it does work as it should

I seriously doubt the air is going to become turbulent inside the intercooler as the air passages are quite smooth, narrow and have internal fins (even the chinese ones I've seen). Also testing is subjective, if the intercoolers arent 100% identical, except that one is curved. Not to mention, I wouldnt want to have an intercooler infront of my car that looks like I had a crash. Not to mention, this isnt even mentioned in any of the more advanced books, which tells turbulence inside the intercooler is not wanted.

Actually the thermostat creates a restriction that causes pressure to build into the block, higher pressure = higher boiling point. Other use of it is to be a valve that controls water flow. Running without a thermostat can cause boiling inside the block. Old rally trick is to cut the center of the thermostat open or drill few holes on the rim, still maintaining the restriction.

"the wavy intercooler mod"

chimmike

I have a spearco IC that isn't wavy like that, but has more of a "twist" to it, laterally. Looks pretty badarse and holds 35psi, lol. I might end up using it on the civic!

I did this to a friends car to day, it help get into full boost faster!!! 1000 rpm faster. Great diy!!!!!

Can I get an ounce of whatever you are smoking? It's obviously some very good stuff.

Go gators!

Alright guys its mine. Its true, I am the creator of the "wavy intercooler technology". Its a patented design that will soon revolutionize the industry. For a limited time I am selling one at an introductory low rate of $60+shipping on Homemadeturbo.com in the for sale section. Dont pass up this great opportunity to own a piece of history. Be the first one in your town to use "wavy intercooler technology".

I dont think u smoke it?!

blinx9900

price to do this mod on my $1200 apexi GT spec core with custom end tanks, i will pay shipping both ways, thanks...

... this reminds me the thread on the ITR forum "if i cut 1 lug off my 5 lug itr can i fit 4 lug wheels?" followed by 5 pages of people saying yes.

Welp someone didn't get the sarcasm in my post cause they deleted it.... :Sighs:

Has anybody EVER looked at the tiny fins before? They are perferated and ribbed to create as much turbulance as possible, as well as to prevent any 1 path from not hitting a fin several times. Laminar air flow (no turbulance) is great for reducing losses (pressure drop), and one reason is because it doesn't disturb that boundry layer of air in which 99% of the heat exchange is happening.

Given that you have 100x time the surface area on the little fins than you do on the length-wise support plates, disturbing the boundry layer on those parts of the intercooler will result in very little gains in heat exchange.

BTW if your turbo is at the limit of it's efficiency range, that extra boost it needs to offset that pressure drop may make it worse. You'd be robbing Peter to pay Paul so he can pay his bookie, per se.

Negatory, speed racer. I am the only one allowed to fist someone's mother, and it only happens if they run an AFC hack after I tell them not to.
