im currently looking for a SMIC for my car but am curious to hear some views and opinions as well as previous experiences with different brands and setups.........thnx

 

I have the M2 large and am very satisfied with it. My temps are excellent and have had no cooling problems with it. It does require you to relocate the battery, and I had to cut a hole in the bottom of my hood for it to close right, but all in all I think its a very good product. What setup are you planning to run it with?

 

Type those four letters (SMIC) into the search function at the bottom of the 3rd gen forum page, and you'll suddenly get a gazillion threads dealing with this subject, the vast majority of which should answer any question you might have.

 

In particular there is one thread on the *ahem* exact subject you have just broached. It's something along the lines of "Which SMIC is best for me?".

 

yes i am aware of the previous threads on this subject.....i am running full exhaust, stock twins non seq., apexi intakes, and a greddy elbow with two additional 720cc injectors.....would also like to run 1bar of boost.....

 

It really depends on what you are looking for... As far as performance, most of them are about the same. I remember reading a thread where someone dyno'd a M2/ASP Med SMIC verse a Greddy SMIC and there was no difference in output power.

However, the better the IC the less work for your turbos to produce the same power. If you don't mind relocating the battering, the Pettic Cool Charge III or ASP Large will be your best bet (same IC core basically).

If you want to keep your battery in the stock location (and some track events have restrictions or need other things done if you relocate the battery) then something like the Pettit Cool Charge II SMIC, PFS SMIC, GReddy or Blitz SMIC's would fit the bill.

Check this thread:
https://www.rx7club.com/forum/showth...threadid=81194

It has info on just about all available SMIC's as well as installed pics....

 

If you get the Large though, be prepared for mega heat soak.

It takes around 3-5 minutes of highway driving to bring my intakes back down to the upper 40's C from starting my car and seeing 75C temps.

 

great thread mahjik!!..thanks to all!!

 

Of course the ASP Large or medium IC's are your best options. They are both available directly from the RX7 Store. This is my completely unbiased opinion : P.

As for the Cool Charge III, throw that garbage away. If the best they can offer is a cheap knock off then they don't deserve anyones business. A vendor should be at least smart enough to try and come up with their own concept of a good product, if they can't they should close the doors and put up a sign saying, "shame on me I'm an idiot and can't think of my own ideas." That goes for anyone trying to make copies of products btw.

Rant off. (smirk) I had a beer or two.

P.S. The person that said they had to cut a hole in the hood for a large IC should send me a private message. Sounds like something else I need to correct by going back to the old ways.

I think the ASP intercoolers ARE the best out there. The only thing your intercoolers don't have Kevin are CARB Legal numbers. ~GET ONE!~

 

I have the Greddy SMIC.

My mechanic had the M2 medium and then went with the Greddy and noticed very little difference on the PFC commander readouts in temps.

The nice thing about the Greddy SMIC is that it fits perfect and that u can do it urself with mediocre installation abilities.

 

Actual numbers I've seen for the Greddy years back don't match up with your mechanic. At WOT and max boost, ~15psi at the time, there was a fairly surprising pressure drop difference and delta temp after a couple laps.

I'm not familiar with the Greddy duct but the mechanical skills required to install an ASP medium IC are on par with those used in changing a flat tire.

If your just comparing the air temps via the commander, for both ASP med IC and the greddy, then your wasting your time, but you might be having fun driving the car. The stock air temp sensor is slow to respond to changes in air temps at its stock location due to heat soak from the manifold. Chuck has mounted his in the greddy elbow and it does react much faster in that position. I think the greddy SMIC would be fine but I just don't link the lower end tank.

Heh. The reason you're not familiar with the Greddy duct, Kevin, is because it's non-existent. I wanted to get one of your ICs, but didn't want to wait until I died of natural causes before it eventually got delivered from M2, so I sprang for a Greddy. I was aghast at their idea of a "duct": a piece of sheet aluminum with some bends in it for the top portion, and a 14" x 14" piece of rubber mat for the bottom. The rest is up to the purchaser to fabricate. What a joke.
I could've spent another $150 to get a Pettit duct and trimmed it, but I ended up ghetto-fabricating my own duct that seems to work just fine. The Greddy is nice if you want to keep the stock airbox and battery, plus, as mentioned before, it has CARB certification, so the smog ***** can't pin you for it.

 

I need to check with him, but believe that this was also verified with Dyno results.

 

Unless you've got a dyno in a windtunnel it won't tell you much of anything about the intercooler.
