horizontal FMIC?

Post by **NeedCAforS13** » Thu Oct 09, 2003 12:36 pm

As anyone who has (or has looked at) a CA in an S13, there is a TON of space between the radiator support and the front of the engine... I was thinking of filling that space with my intercooler and I've been looking at how some other people have done it (and have come to like this idea best!)

Look how SHORT those IC pipes are... even more throttle response from my high compression motor!:) What do you guys think?

I'd obviously have to cut some sort of hole in my hood, and maybe make some ductwork to channel the flow better, but I've seen these on rally cars, and I loved the idea...but this was the first s13 i'd seen with it (with out cutting the radiator support that is)

ah yes the V-mount fit, the radiator and intercooler are lined up in a V, this provides excellent cooling, make those hood vents work!!,

wunder if any one sells those kits, because most v mount kits i see are for rx7s

Gonna be prone to heat soaking...

booth signals s13's in the newest or second newest superstreets have em like that...cept theres a metal plate over the radiator...or maybe it's just really shiny...but i really wanna do this too...dont want people knowin what's really under there...thought that might help ya some

It's more to direct air flow than anything else, It would certainly help to get more air flow, but it won't help the heat soaking.

there weas allot of arguement about this on fresh alloy a while back, i think the throttle response may be worth it if your cooling system is well thought out, you got to find a way to mount the radiator so you can fill it up, if you look at that guys photo he has a cathc can with a rad cap, that probably ahs a line to top up the rad, you got to have the rad cap at the highest point in the cooling system, or you cant blead it properly.

If you want better throttle response, get a N/A motor baby!!! Hehehe, JK, I just had to throw that in there. Anyway yes, this can be done, would I personally do it, no. The reason is that I'm a pansy and I like my A/C, and to do this, you'd have to ditch it. Maybe if I was building a track car only, this might be an option, but for a daily driver, there isn't enough money in the world.

there was someone who got the ac to work with this set up... placed it belw the radiator i think... with a fan sandwiched between it and the rad.

Post by **float_6969** » Thu Oct 09, 2003 12:36 pm

That's an awful lotta work....

any idea how he (or anyone else) might have this plumbed? I'm really serious about this idea... lol i was just out there test fitting my intercooler to see how much room I had to work with:)

i have a couple pics of the signal cars...i took them at the dgtrials event at english town...i can email them to you if you want... or im me at ride 4 lame

yeah please do! [email protected]

thanks,Sean

the lay down set-up is used for many N1 cars that run higher grade fuels, and can take that extra heat, and they do it for 2 reasons. 1) the air coming in isn't shared by both the I/C and the radiator, they both get fresh cool air, and 2) throttle response is imparative in N series and GT series racing.

FCs do it 'cause they run hot, and need the air to not be shared, you get significant gains on a rotary buy using this set-up.

If I had the extra cash, I'd do it, due to the fact that I haven't found any S13 aero kits I like, and would like to maximize the stock air passage,

as far as heat soak goes, the air going OVER the hood helps ALOT with cooling the lay-down core, air moving over the hood actually pulls the air through the I/C, aiding in it's cooling abilities.

I sent the email hope that helped....

Post by **NeedCAforS13** » Thu Oct 09, 2003 12:36 pm

those pics were great:D thanks!

I also found this thing... kind of like the one in my first post...

"This filler neck is designed for cars where the engine sits higher than the radiator. These necks give you an easy fill point to ensure all the air is purged from the engine."

sounds about right to me:)

I would think it would HELP heat soak, because hot air rises. As the intake charge heated the intercooler it would push that air up, which would then draw cooler air up through it.

so is there a huge difference between doing vertical and horizontal if i'm gonna be puttin out about 300hp and runnin the highest octane...i think 91 here....thanks

Post by **NeedCAforS13** » Thu Oct 09, 2003 12:36 pm

nope... no HUGE difference... but there might be somewhat of a difference in efficiency... I'll let you know if I try it;)

there's no real reason to do it, other than you're running sustained RPM, like in GT and N1 racing, and you need the MAXIMUM amount of air going to the radiator, since they run higher octane fuels, they don't have to worry about I/C'ing as much.

Sean, fight the urge. Be normal. Ok, nevermind...

bah! this coming from the guy who uses:fruit in his posts...hehe

but anyways, I found yet another part of my project idea... I found this hood, and was thinking the vents are perfectly placed for my intercooler! Its borderline too much though... ruins the sleeper look I'm going for? We'll have to see... its made by RS MAX called the: GT-300 style vented hood... gotta email about price.

here's some pics:

what do you think? good, bad, ricey, too much?:) will it work well?

Sean

Post by **Axlerod** » Thu Oct 09, 2003 12:36 pm

Sean that is just like the Koguchi hood I showed you... very NOT ricey

I absolutlely love that hood. It's probably your best bet for airflow. Notice its cowled as well, air doesnt sit under there for long! I dont think you can go wrong with it.

Post by **Nismo1182** » Thu Oct 09, 2003 12:36 pm

I like that hood, whether theres an intercooler under it or not.

Sean, YOUR GONNA DIE CLOWN!!!

Post by **Drill_Sergeant** » Thu Oct 09, 2003 12:36 pm

i believe another big reason they do it is to protect the IC when drifting just like zipties...just thought id bring back an OLD topic

Post by **float_6969** » Thu Oct 09, 2003 12:36 pm

Drill Seargeant, the 'D' and the 'E' arent in the center... but in I think thats a good idea, that I didn't think of! My intercooler has bent fins all over the place...

Side mount AC for those of you who want the V mount AND to keep the AC:

Some of the Rx-7 guys run A/C.
