It works with stock y pipe, efini y pipe, air pump.

It will work with any kind of hoods: stock, mazdaspeed, knight sports, Scoot, RE amemiya, etc.



I don't know if it will work with the RE intake. I need you take a pic for me and do some measurement for me as well. Thanks.

Please go to my website. I have all the info and FAQ there.

It should answer most of your questions. If not, you can post here.

The intercooler is easy to remove. Only 2 bolts and 3 silicon hoses. I am going to cut the pipe from the IC to the throttle body into two pieces and put a silicon hose joint there for easier install.

Why V mount is better than a SMIC:



1. The SMIC air exposure is fixed by the duct. Even if you upgrade to an aftermarket bumper, the air going through the SMIC is the same. Your SMIC will not get any benefit of that. But ifyou use a v-mount, you can increase the air flow going through the intercooler to increase the efficiency.



2. There is no such thing as intake, intercooler, radiator fighting for air. The total amount of air going through all of them is fixed, determined by the frontal area of the bumper. Even if you have a cold air box, SMIC, and regular stock mount radiator, the total amount of air going through them is still fixed. The benefit of V mount is that you will be able to distribute the air flow effectively by using ducts. You can never do that with a SMIC.



3. It simply works better with a vented hood which is getting popular now than the SMIC.



There is a few long threads on the rx7forum on this. I have explained in details there. You can go there and check it out. Thank you.

1. You are correct the smic air flow is fixed by the duct and its also "tuned" for the size IC. The IC core cant flow its size in air because the core is about 70% metal which doesnt flow. It only flows about 30% of its size which is why my duct was 30% the size of the core.



2. Why wouldnt you be able to distribute the airflow with a SMIC set up? Even the stock system distributes the airflow. The way I see it is that the V mount doesnt distribute without ducts, which is what I was saying in the beginning....which was based on me not seeing any ducts. Now that you say you are including duct, I agree its going to be a good setup. Without the ducts though I dont think its all that great.



As for your test, I dont know all the conditions so its hard for me to comment. How long were you driving? How fast were you going? Was the temp 80C cause it just wasnt enought time? Where did you take your air temps at? What rpms were you running.



I dont expect you to answer those, I'm just pointing out that there are a lot of factors. Mine also shows ambient readings under the right conditions, right conditions being the key word there haha



What made you decide on the Vmount instead of something like a liquid/air set up? I'm thinking about a liq/air set up now.



And yea, I've seen the thread on the other forum already.

Hello Stephen:



Here are the answers to your question:



1. You can't caculate the air flowing through the intercooler like that because you are not taking pressure into consideration. Even with the same area of inlet area, with a higher pressure, you can get more air through the core. But how much air going into the channel is already pre-dertermined by the size of the inlet. To think of it in an easier way, if you can increase the size of the inlet and still getting the temp down, you know the size of the duct is not big enough.



2. You definitely can distribute the air with the SMIC but how much you can distribute is fixed. Let's say if you get a bumper with larger mouth, can you get more air flowing through the intercooer? You can't because the size of the intercooler duct is fixed. You will be able to get more air flowing through the intercooler on the v mount even without a duct because right now there is more air flowing into them. Even without a divider, the intercooler will still get more air flow than your SMIC because how small your intercooler duct is. The key is the size of the inlet. On the v mount, the size of inlet is the openig of the mouth. On the SMIC, the size of the inlet is only about 3"x10" at most.



3. When I did the initial test, the car has been driven for 50 miles. The car is fully warmed up. The air temp is taken at the manifold read by power fc. I am accelerating from 50-100 mph running 14 psi on T51R kai so about 4000 to 8000 rpm on my automatic in 2nd gear.



4. I don't know how you can do a air/liquid intercooler on the street driven FD. You either need a ice tank or another heat exchanger like the radiator. For the ice tank, you can pretty much only use it on the drag car. For the exchanger, we don't really have another place to put it do we?



The key point is the inlet size of the duct or air channel. Thank you.

I don't know about that V mount, I kinda like my fmic never had a problem and it looks good

yayer

this is definitely what i'm getting when it comes time to upgrade the ic

Mazdabation

I'm with you on that one

FikseRxSeven

this is really cool, i dont race much though....... so i dont know if i really need it....... but



i really really want to get this eventually
