He could use a couple washers under the hood hinge bolts to raise the rear of the hood a bit and then remove the weather strip to create an area of low pressure for the air to flow to under the hood, but I don't know about putting the SMIC there. I would think there would be issues with hot air rising up through the IC from below (especially when driving), and it would be super prone to heat soak in the staging lanes or at the light. Dunno.
At least you're thinking outside the box to some degree. If this doesn't work out, it could be a step on the way to something that does.

hey I appreciate all your comments. I understand that its not the best way to go. I totally understand that. I had a few parts I had collected here and there and I just put em together. I am just trying to have some fun. As far as cooling It should work. I installed the intercooler before I had the turbo on, and my car wouldn't run on operating temperature. it would stay a lot cooler. I didn't post this pics to tell all the tuners I am a genius I really didn't mean that. Just wanted to show something different. other then that it s all cool. I still haven't ran it yet. Oo I forgot the hood scoop its going to look a lot better when I put the mesh grill on it. it will definitly change the way it looks I'll post more pics depends on the request. We'll see what the mitsu can do.

You may wish to reconsider the wastegate. the Turbonetics gates are awful and you've not routed it's exhaust properly. You're going to melt something if you don't run a dump tube.
The Deltagate was my first external and I can tell you it's not what you want. The smaller TiAL gates will bolt right up to your existing flange and work much better.
Think about a N.A.C.A. duct for your top mount.

Yeah the hood scoop could stand to be toned down a little but other than that it looks cool that you are trying something different.

The base of the windshield/back edge of the hood is about the highest-pressure area of the whole car. Lifting the back of the hood makes air flow into the engine compartment at speeds over 30.

I'm just getting broke off left and right this week over here.
Even so, I would think a set up like that could use all the air it could get. Oh well.

Not necessarily. This is the same principal as cowl induction hoods. There are tons of cars especially camaros that run cowl induction.

Air moving through the hood will reduce the high pressure zone at the intersection of the hood and windshield. Splitting hairs for sure but downforce will be reduced.

lol what do you mean by "pointless? If us turbo guys can run 17 psi and run a high 12 second pass on a stock sidemount with longer piping then how is his setup "pointless" coming from a mid 16 second car? I think it definitly added power so please explain yourself.

suieclipse has his opinions, and just about everyone on this site has learned to ignore him.
I think it looks cluttered, but it is deffinatly original. Don't like the scoop much though, that could use a little work. As far as temps go... I think it would be terrible. The 420a runs so hot as it is, adding your IC in there can't help. I think you should try to create a hood with a scoop in the center, almost like the STI. Just on the underside of the hood, rout the air to the IC. SRT-4 guys do this all the time to get cold air to their filter.
Very original, and great work.
To the kid who wants to know about the t25... just read a little bit... nobody likes that turbo

i think making a heat shield to go between the engine and the IC would do wonders. i dont think there would be room to route the air from a center scoop to the ic. i think he should do a scoop like corbins.

acutally a intercooler cooler would be a good idea. Nitrous or CO2.

How true.
One thing to think about is even if you get air to the intercooler you still need a place to send the hot side of the IC. If it's sitting up against the engine your not quite helping it. Still a cool and original idea if you can get it to work without heat soaking the core.

If you're trying to flow air through the radiator and out through the bottom of the car, then having air coming in the back of the hood to fight it will be bad. Raising the back of a hood is bad. It is stupid. It only cools things down when stopped.

hey guys. I really appreciate all the things you guys said. And everything is true. The hood, the whole car needs a lot of body work. As far as heat I have no problems what so ever. The car runs the same temperature it was running before turboing it. I 've even taken it on the high way and I feel no difference in handling it or any problem at all. I have been out in the field for more than a week and I was really surprised when I saw all this good comments thanks yo. Ya motivate me to try some more things. Another thing there is plenty of room between the block and the IC. They are not touching at all. The IC is not touching to anything. I moved the computer to. I mounted it a little lower. No problems what so ever so far. I have one more picture I have to show you guys. I will take it as soon as possible and I will post it. thanks yo .
