top mount IC opinions

[silver eclipse]

If thats the stock side mount just relocated i dont think theres a point even with what i said earlier. You still have the ristrictive and small size of the intercooler. If u could get a decent sized intercooler to fit, or a supra side mount (never seen one in person, so dont know the actual size), it would flow better but then u have fitment issues.

Just looked at your pics. That looks ghetto-fabulous...minus the fabulous.

 

[Burnett03]

yea i built a hood scoop on top of it and cut the hood out (profile pics) but i was trying to figure out how to block it off from the engine heat, aluminium sheeting maybe??

ewwww

 

[kgtalon95]

Do us all a favor before you do ANY other mods and get your body straight...........My god in heaven WTF

Also, that scoop is not going to draw enough air until your moving pretty fast by the looks of it. Notice how big the sti scoop is??? Its that way for a reason!!

 

[96blacktalon]

Don't take what all these people are saying too hard. At least you're doing something a lot of people couldn't, or were afraid to. personally, I think, yes, it is a bit ragged looking, but i kinda like the "road-warrior" look. it's unique. Some people are more concerned with "bling" or "I.C.E." Certainly not me. or you, appearently. An idea though, if you're going to put an aluminum sheet behind it, leave plenty of room for air to pass out of the IC. Also, i don't know how you did your scoop or the hole in the hood, but you should match the hole with the size of the IC, and put a rubber seal around the hole on the hood so that it seals to the IC with the hood closed. also, yes, you need to increase the angle on that scoop. From a larger plenum at the front, to smaller at the back. Think Magnus SMIM. Alright, that's all i have to say. Keep up the creativity.

Yeah I wouldnt take ALLOT of what most of these guys say too personally man. I see in their profiles all the time they have these mods listed and all this money into their cars but no pictures. You think if you could put all that money into your car, you could afford to buy a camera and share what all you have done to it. I am not saying EVERYONE so dont take it that way. I just have noticed a few people since I have been on here a short while, just dont agree with ANYTHING you say or do to your car. If you like doing it and brings you happiness to do it. BY GOD MAN DO IT !!!

Now thats some short route piping! I give you props for having the balls to attempt something like that.

 

[bob123131]

Yeah props on trying it, but the stock side mount is a very restictive side mount. I dont know if you are going to loose power here, but that scoop is not going ot provide enough airflow. There will be to much heat also. Maybe u can go to a small or medium fmic and put it horizontl from battery area to fuse box to where filter should be. I dont know how u could pipe this in any way but if u really want to go with the top mount u are going to need to change to larger intercoller if u plan on getting any good times.

Hey now!, I don't have any pics. Ha Ha. I promise I'll put some up when I get back to Texas next month. 'Till then, everybody will just have to take my word. Or I guess I could show all my HUGE bills, and all the debt i'm in. but, yes, I do have a camera. Gotta have one for the ladies...

[RedTurboEclipse]

wow looks ghetto.. but u did it all right..

although it seems like more trouble than its worth..

 

[sherwinz28]

It does look ghetto but man that is a neat idea...has to be the shortest route piping I've ever seen. I'm more into the clean look...not really bling but just clean. Your car at this point looks better then mine though so props to you, I bought mine for $250

 

[almostquick]

I'm sort of digging your rat-rod style you got going. to make your project better I would get a Supra SMIC weld custom endtanks w/ 2.5in outlets, make a bigger j-pipe and the rest of that very short IC piping 2.5in also if you havent already. as far as scooping the air, I would recommend you to go check out a mustang mach 1 and look how the scoop is connected to the motor and goes through the hole in the hood. so your scoop would be connected and sealed around the front of the intercooler and then come up through the hole in the hood you made , if you get what I'm saying. good luck with it and get some track times, from stock to relocated to see if it was worth it.

 

[92awdgsx]

the only problem i see other than it being a stock ic, is the scoop is WAY too small. other than that it should work good. maybe a heat shield for the ic too.

 

[never2muchBoost]

talk about short route piping

 

[HighPsi92GST]

At least you're doing something a lot of people couldn't, or were afraid to. personally, I think, yes, it is a bit ragged looking, but i kinda like the "road-warrior" look. it's unique.

a BIT? the front end is half missing and theres a peices of metal welded to the top of the hood

Nice idea for the IC though. Now spend some money and get new parts for the front of your car...

 

[boostedinaz]

Take everything I say however you would like. These are just my thoughts.

At least you're doing something a lot of people couldn't, or were afraid to.

There is a HUGE difference between trying something/being inovative and just doing something that will work half as well as the original plan. Sometimes things arent done for a reason. Looking at this car and this mod is definitly one of those things.

Some people are more concerned with "bling" or "I.C.E." Certainly not me. or you, appearently.

You can have a very nice car that is also fast. Bling really has nothing to do with this except to justify a crappy looking car/mod.

Keep up the creativity.

Jeff

I agree 100%, but put some common sense behind it.


So here are my technical worries.

For one the stock sidemount blows. It works well for the first couple pulls then its useless. You have now put it in a hot environment and only provided minimal air flow. The scoop isn't big enough and if it was were is that air going to go? The engine bay is fairly cluttered and there is alot of stuff under your intercooler so the air flow will marginal at best.

So to sum it, you took a crappy sidemount from a space that had a TON of airflow and put it in a hot spot that has minimal air flow.

Again, these is just my observations. Good luck.

One major problem with a top mount design with a forward facing hood scoop is that this placement puts the i.c. intake in a low pressure zone. Counter to what everybody thinks, you might have airflow reversing direction or just stagnating. Basically hot underhood air flowing up and thru the hood scoop, not the otherway around. Scoobies have this very problem.

The stock sidemount was already in a high pressure zone, better than even a front mount since there is no radiator blocking the rear, and no radiator heat soak either. Sidemount is not really a bad compromise from an engineering point of view, other than the small core size required.

Didnt even think about that. Good call.

If air moves at 2 different speeds the air that is moving faster, over the air scoop, will have less pressure than the slower air, under the hood. So it is a possibilty that you may actually force air out of the scoop as opposed to in the scoop.

 

[HHIVR4]

Top mount would have to be dirrectly over your mani..It would be very hot

 

[1993eclipseGS]

You could always just get a fmic.. Woulden't it be worse in there with all that heat, Aposed to the stock location where it actually gets air to it..

 

[Malero5]

Lets think about this logically. Heat rises, cold air sinks. If you are idling and go to launch the first air you are going to pull is the hot air comming form the engine. The body is also designed to pull air into the radiator/wheel well. I am sure when subaru made their car, they took extra care to do two important things. Make sure the air flowed correctly from the hood on up, and thatt he exhaust manifold didnt heat up the air under it. There could even be issues with reverse airflow (as mentioned above) that could actually hurt your ability to breathe.

However, there is some novelty in your idea. Shorter hoses mean more low end torque. If you were to cut a much larger scoop and get 2.5 inch pipong/a better sized intercooler then you could see some sort of benefeit. You would alos need to put some sore of heat absorption device between the manifold and the engine. I'm just worried that without a well working turbo that some N/A honda is gonna smoke you Please spend the 200 bucks at your nearest junkyared and pick one up.

First off, good job on being refreshing and original.

Unless you can fit something larger than a smic then this is not worth it. The wrx does it because it's engine sits low and so there is plenty of room for a big core. You will see some 240sx owners custom "v mount" a core which is similar to the wrx set up but this is only because there is so much room between the engine and the end of the engine bay.

Also as everyone has told you the scoop is too small but more importantly not the right shape. Scoops are very difficult. The wrong shape will either not draw air at low speeds or allow a high pressure area to build up at high speeds thereby making air pass over the scoop entirely. This the problem with "ram air" domestic set ups. They only work at certain speeds.

Basically you have a good deal of work to do if you want to make this as productive as the worst fmic setup.

 

[HHIVR4]

Subabru have horizontally opposed engines so there is alot more room up top.Subs upgrade to fmic just like everybody else.

 

[HighPsi92GST]

Subs upgrade to fmic just like everybody else.

Exactly what I was planning on saying.

Never have seen a 4g63t with a top mount. The auction says it is a 6bolt but doesnt directly say what car it is from. What car was this motor from? I have an idea but cant remember the name of the car. The tranny is AWD too, just curious.
