rx7even, gohorns, have your ICs arrived?

forcefed1: you ever find the link with lots of pictures?

 

Does it look to you guys like the airpump is removed?

 

yeah I posted teh link back on teh last post of page 2.
check it out.
Did any of you start making an intake yet.
I currently have all teh parts Ill need asside from teh intake. I'm going to make one from aluminum. the only thing holding me back right now is time.

 

I started pulling the stock IC, then needed the car and had to put it back in. Weekends go way too fast.

 

I'm not sure if mine has come in or not. Unfortunately it's being delivered about 2 hours from me, so I might not get it for a week or so.

 

I've ordered some aluminum sheet from mcmaster-carr for a different project. I got .062" 5052 as I have a number of 90 degree bends. I may use a thinner gage for the duct.

There sure isn't much space for the duct to pass above the radiator...

 

ups delivered mine today. great craftsmanship and nicely done.

 

Good to hear, gohorns.

Like I mentioned, I started pulling the old IC. It's not obvious how to pull the old IC duct out. Know where there is a procedure posted?

 

This is how I did it when I installed my radiator:

Remove battery tray
Remove IC
Unbolt the A/C condenser unit
At this point you should be able to loosen the duct, you have to play with it, bend the condenser and the lines a little to get the duct out.

Hope this helps

 

Thanks. I was hoping I didn't have to remove the AC condenser.

 

How far are you guys on the project? Have you made the brackets yet? The front of the IC is held by a L shaped peice bolted to the front but how are you going to hold the back of IC in place?

 

I've been slacking. I may be getting a new radiator, so this will impact fitmant...

Since SR discontinued these, maybe they'd send us some installation instructions for their kit.

 

Stock mount radiator should not impact fitment. I got the Mazda comp and its a drop in. Costs a little more than the other but installation is an ease.

 

i THINK that if you get a HMIC it would be more for the circuit racing, and front mount for like drag racing... or you can go with the "V" style set up .... what do you think ??

 

I suppose with the v-mount you eliminate the belly pan. I think this is a bigger project than I am after. I'd also think you want an IC the same width as the radiator. The SR HMIC is narrower.

It looks like you effectively split the air between the IC and the radiator. I think you could spend a long time determining air flow characteristics with this configuration. I can control the amount of air the IC gets with ducting, and it's more similar to stock.

That being said, I think the v-mount is a good idea. Isn't this configuration fairly common in Japan?

 

Did rotary extreme ever come out with their HC?

Eddie

 

Yes, I'm interested in this answer as well. This seems to be the only IC that will work with Efini Y-pipe WITHOUT modifying the Y-pipe to any extent!

 

I thought the Efini y-pipe was a direct replacement for the stock y-pipe/airpipe.

 

Pettit cool charge II is a decent IC that works with the Efini Y pipe but is overpriced and temp drop numbers are'nt even close to M2 Med.

 

this sounds like rotaryexreme.com hmic is a great deal.

luigi

and yes it did come out

 

has exchanged emails with me regarding his HMIC Rotary Extreme. The IC kits are done, but the inlet ducts are not...

Chuck says the V-mounts IC/2-inch think Comp Rad are complete and available; the V-mount design is used on track in Japan FD race cars.

 

Well, I guess rotaryextreme doesn't agree...

 

Chuck's stuff looks serious and custom-made...

I'm anxious for them to get the inlet duct done for the HMIC...I'm sure I will order the RE HMIC, as it can be used with the Efini Y-pipe, and just about any intake.

Chuck says the HMIC's couplers will not pop off like they do with the M2 Large IC's because Chuck's HMIC is rigidly mounted via a bracket. There apparently is no movement once the HMIC is in place. Without the movement, the silicone couplings will not work themselves loose like they do on the M2's couplings.

From what I've seen, the M2 is not rigidly mounted. It's held in place with the 4 silicone couplings. With the motor moving around under throttle, it's easy to see why the M2 Large IC couplings are constantly DECOUPLING, and causing boost leaks out on the road race circuits!!!

Rotary Extreme has their own CAI in the works, and I might consider that one as a nice complement to Chuck's HMIC...?

 

I got a SMIC and my brand new SR HMIC is for sale if anyone is interested.

johnchabin ... Yes i see alot of V-mounts ... but i guess its just how you plan on driving your car.... Will you be running your car hard enough for the radiator to be a big factor, or will you be on the straight away track where you need the air for the intercooler ? its all in what you are going to do ..... i guess.
