Spy photos of the Rotary Extreme H-Mount IC
Hi guys, after a couple of weeks of brain storm and careful research, we have finished 75% of the horizontal-mount intercooler. Now we just need to finish the intercooler duct and the kit is complete. The intercooler kit will have the following characteristics:
1. It works with stock hood and any kind of aftermarket vented hood. YES!, it even works with the most popular Scoot replica hood as well!
2. It has a lot of clearance between the IC and the hood. You will have about 3-4" clearance so even with a stock hood, the hot air can still vent to the back of the engine.
3. It works with stock turbo and efini Y-pipe. It will work with a single turbo as well.
4. It will need a Greddy elbow.
5. You will need to either get a smaller battery or relocate the battery to the back.
6. It will work with M2 intake, greddy intake, and pettit intake. RE Amemiya and APEX intake unknown at this time, unless someone wants to donate the car for test fitting.
Now here are some photos.
If you are interested in this newly develped product, please contact me at rotaryextreme@aol.com.

Before I answer that question, I have to give you some fact:
1. This intercooler core is a newly developed one and it flows about 23% better than the large stock mount intercooler. 935 CFM (R.E. HMIC) vs 760CFM (large SMIC)
2. The core is tube and fin and the air can flow through better than the bar and plate intercooler.
3. There is 3-4" clearance between the Scoot replica hood and the intercooler core surface. The Scoot replica hood sits lower. On the stock hood, you will have 4-5" clearance so hot air can still flow to the back like the stock mount IC's.
Even with a stock hood, the intercooler will perform the same or even better than any of the aftermarket stock mount IC's. But with a vented hood, it will perform even better.

any comments?
Back then a lot of people were interested in the HMIC and now it's done but no feed back? Is it too late?
Anyways, another photo to show the clearance between the hood and the intercooler surface. There is a lot of room as you can see in the photo.

One more question: Which large SMIC are you comparing flow rates to?
And a comment: I like that you can use it with the efini y-pipe and pretty much any intake. That should really open up the market for the kit.

I don't know if $1450 will include polishing at this time but I think at least for the pipes the will be polished. I need to find a nice polishing place first. I will know for sure after everything is ready.
Air flows better through the tube and fin than the bar and plates.

Okay Chuck, I'll bite. Here's two easy questions:
- will the finished kit be polished?
- why go with tube&fin, instead of bar&plate?

The large stock mount IC is the one that has the 13"x17"x3.5" spearco bar and plate intercooler core. All the flow rates are given by Spearco. I didn't just do the test myself or made it up.
I am trying to make this as universal as possible so you don't have to spend additional money for something you already have. Very considerate, right? =)

Looking great Chuck!! Can't wait to see the finally product!!!
I'm glad to see your building this as universal as possible so we can all benefit using your new HMIC... I think it being polished and nice duct will result in a BADASS product... keep it up!!

Chuck, one suggestion I would have for the HMIC would be that the inlet pipe (turbo to IC side) should be removeable. Essentially it should have 3" or so coming off the end tank and be connected to the properly shaped pipe to connect it to the stock or Efini y-pipe via another sillicon connector. As pictured, your setup would not work for those that are currently running the M2 or Crooked Willow without going back to the stock y-pipe connector. That means more tube length, more curves, and more restriction. There could be two pipes to accomodate the stock and aftermarket setups where the airpump is removed. It would facilitate single turbo owners as well. would consider making the end tanks asymetrical and smaller in volume as well. All will help boost response. End tank design is critical, much more so than people think. Looks great overall though. ARe you making ducts for the back side of the IC to be used with the Knightsports style hood you sell? Perhaps a duct going to one of the vents, leaving the other side open for engine air heat?

Forgot to mention...there was a really good article on IC end tank design in RaceCar Engineering (published in GB) a while back...I'll try and find the article and scan it in.

i wanted to know if you still plan on selling the kit with hmic and radiator as on your website? if not will the hmic work with any radiator (obviously with some modification and in the stock radiator location.) if so, the stock radiator location is tilted forward wouldn't it work better if the radiator was tilted backwards, like the knightsport version?

That's what I meant. If you are talking about the charge row, the fins inside will play a big part on the flow of the air inside the charge row. And for that, you can just tell by the CFM and the pressure drop of the core.

Okay, I think I understand. You mean the cooling air flows through a T&F better than a B&P? You're not talking about the charge air with that comment, correct?

I think you got confused between the HMIC and the V mount. The HMIC retains the stock radiator but it has a intercooler inlet duct that feeds air to the intercooler like the regular stock mount. I haven't finished the duct yet. Once it's done, I will have photos posted here and on my website.

The intercooler is not fully done and the welds were not cleaned up.

I will keep the turbo outlet pipe on the intercooler. If you have more silicon hose joints, they will pop off more easily. This way you only have two silicon hose joints and they will not pop off at there is no way for the intercooler to move back and forth because the core is mounted on the chassis.
If you currently using the M2 or CWC intercooler, you will have to use the stock y pipe or efini pipe. I don't think this will be a problem because if you want to sell your current setup, you have to sell it with the pipe that comes with the kit. Otherwise, how is your buyer going to be able to put on the kit? You will be able to keep the air pump with my HMIC setup.
The end tank is asymetrical. One end if 2.75 and the other end of 2". You can see them better with the photos that I am going to post.
I will make the outlet duct as a optional part. I will probably just make them with the Scoot hood and the Knight sports one since they are the only two I sell and I don't have access to a Mazdaspeed one at this time.
