Last week I installed my FMIC , pics at :

Wow that's an awesome setup. I hate to say it but its gonna look a lot more aggressive too. I really think the the piping looks great.. Are you getting any issues with fitment of the bumper.

 

i count 6 90 deg bends. that cant be good for flow. thats a very clean install. the mounts are great. but im not so sure about the efficiency of the setup. thats a lott of bends.

only six??? Let's not stop there...

At least:

1 - on the primary inlet
2 - on the secondary inlet
3 - on the y-pipe
1 - on the cross over
5 - on the turbo side of IC (yes I'm counting the one from the end tank into core )
5 - on the elbow side of the IC
3 - from elbow into motor

THAT'S TWENTY TOTAL

so what's 6 extra in his IC design???

 

id say that might have something to do with pressure drop. . . thats what the extra 6 are. . . BUUUUUUUUUUUUD.

i only counted 6 cause there were some that cant be counted due to mazdas design or the inlet to the ic. . . dont count that. . . cause most all of em on an FD have those bends right at the core.

heres the reason i pointed that out. https://www.rx7club.com/showthread.p...highlight=fmic

again, i think its GREAT that you made yourself an intercooler kit. . . im sorry that i made some criticism. i didnt mean it in so much of a negative way. the way this intercooler was done is the reason i did mine. . . the way i did mine. better efficiency. what is it. . . . flow drops something like 25% per 90 deg bend. . . or something like that. at any rate. . . flow drops at a bend. . . so WHY NOT make them minimal.

Nice job to both of you, I cannot believe the timing because I was planning to build one like it.

What core size and end tanks you using? and supplier?

 

It looks like you removed the bumper from the support area.( The bumper being the big solid piece across the front.)

Have you had any wierd flexing in the front end with that missing? Other than that ( and I may be incorrect that you removed it) Very cool set-up.

 

Well, if its not the most inefficient IC piping I have seen, its gotta be close

 

That bumper is going to block a lot of air. Might as well just cut it out.

 

I just whant to tell you who thinks you know everything
about pressure and cooling that this setup dropped my inlet temp and increased the hp alot.

 

looks good

 

OMG, another FD bites the dust. Yeah his front end flexes, he just doesn't know about it....

1st you decided to go custom instead of buying one off the shelf because why? Did you think the welds and extra bends in the IC piping would help flow?

2nd you took the bumper reinforcement off, your car will get bumped and it'll get totalled out.

3rd and actually my biggest problem with the entire install. You CUT OFF the structure of the car that holds the frame rails together in front. This is NOT a good idea, it weakens the structure of the car and really makes the car vunerable in any type of front end bump, not to mention the addition flexing the front will see in day-to-day driving.

For all the newbies, this is a perfect example of how not to mod your FD.

 

No ****, Sherlock. Going from stock to anything else will result in that. However, if that system was designed intelligently, it would do more.

Your changes in inlet temp, and hp increases aren't worth the loss in structural integrity. Nor will it be worth rebuilding your engine because you didn't get it tuned for more hp. But you don't care, as long as you have a big IC in the nose.

 

It looks great. Despite flaming going on here, do take note of what others have said about safety. Other than that, I do like the way both pipes come to center. Optimal or not, it looks cool.

 

If you "turbojeff" and "PVwerdieck" put on your glasses
and look at the pics all the orginal parts are there , bumper reinforcement are not removed !!!
I have cut out the structure between frame rails but as you see I have moved it up abit with a new bar welded in place.

This setup is much better then orginal IC . I get cooler air and thats the point !?

I have read many threds in this forum and you two are the ones who spreads most negative stuff to all happy RX7 owners.
I olnly get tired of you who has answers to everything in the world.

Thanks........

 

Let 'em hate. You achieved your goals and you're happy. Custom stuff rocks.

All I can say is that many of the kits out there are functional but not very optimal. The best I have seen is the Blitz FMIC and the HKS v-mount, HKS even addressed the poor elbow design. Stock mounts are questionable in theory but have proven to be very effective on the road courses where coolant temps are of paramount importance.

 

jeff. . . can you tell me how "structural" that piece is in the front? how much does it drop the rigidity of the frame. . . what percentage. . . i could see something wrong with removing caps (if they existed) from the ends of the frame rails, but thats not the case. . . HOW MUCH FLEX OCCURS AT THAT POINT?

Though I'm still new to the rx7 club, i must emphasize that we own a "sports car" not a cheap honda or toyota. Though the idea of installing a custom made FMIC is tight, i would have it inspected by an rx-7 specialist and see what they would say? Because the RX-7 is a quality car... putting "inexpensive parts" is in way... insulting. Either way much props but get it checked out before driving it much further.

 

I´m not finished with the car yet ,its progress pics !
I know that many of you thinks that it´s wrong to remove parts from the car and I´m still working on a new bar between the frame rails.
BTW its no inexpensive **** I´m putting in. I have not found any setup I like, that´s why I made a coustom setup.

Let´s bury the axe and just be friends here !!

 

hagge had the same idea i had. . . i didnt like the fmic's that i had seen. . . and the core i stuck myself with was in no means optimal size for an smic!!! haha.

flipmode, what makes you think this was inexpensive? i dont know how much hagge spent. . . but i spent over $1k. . . and i KNOW i have a better fmic that the same money paid for. this myth about "cheap" parts has got to be the most ridiculous idea i have heard of. . . just cause its a "sports car" doesnt mean we gotta spend a life savings on it!!! putting "inexpensive parts" is actually in way. . . SMART!!! saying its insulting is likes saying we should be spending 500.00 + on toilet seats like the pentagon or something. . . cause hey. . . thats your *** youre putting on that ring-o-plastic. . . and my *** doesnt touch anything "insulting".

btw. . . how long have you owned your FD?

paul

 

yeah, don't listen to the retards. they think that the only way to work on cars is to buy a "kit" because they are to lazy and lack the creativity and knowledge to build something them selves. but hey i guess if it costs more that means it's better right?

 

The negative opinions are valid ones(don’t just shake them off as flames), and I too think you should reinforce the front structure of the car as well, from the pics you have I don’t see any helpful reinforcements that directly take place of what you removed torsionaly wise

But it takes guts to make something like that and some talent you should be commended on a pretty good job. You too Paul you have any new pics?

I find the most rewarding thing is not the actual part ,but the experience and knowledge you gain and also the fun you have just building something for yourself that you can tell other people that are interested were you got a piece, that you made it your self

But it does have an awful lot of bends, which will increase pressure drop significantly. Perhaps a better solution can be worked out in the future. Good luck and good job

Here are some pics of the stuff I have been working on http://www.nopistons.com/forums/inde...howtopic=40047

 

did you trim down the re-enforcement to fit the intercooler ??

 

Nice work rotarypower101 !!!

Yes the pipes are going to be straightened out soon.
I´m glad somebody understand that my plan isn´t wrecking down my car and do it undrivable.

If you meen

 

If you mean the fiberglas reinforcement behind the bumper ,yes a little bit is cut of to make room for the IC
