914 GT 3.6 Ferrari Build, - Mechanicals coming along, electronics soon! Options

OK, I'll tell you what!

Slice it into quarters and see if can be used as the basis for a radiator venting system!
Clearly a ways to go but, so far, I'm encouraged! It's nearly a perfect fit. What are the odds? (IMG:style_emoticons/default/smilie_pokal.gif)

And no, that's not the radiator I'll be using - it's just a mock-up part.

I like venting into the wheel wells but what about the bottom louvers? Would you remove them and close that off? (IMG:style_emoticons/default/beerchug.gif)

[technicalninja]

The BIGGEST problem with radiator shrouding is the amount of restriction that they create behind the radiator.

MOST (almost all) are too shallow. Like the one that is currently mounted to the radiator.

That one IS NOT!

Now ending it directly against a wall isn't good either but I'm betting you have a solution for that.

That looks beautiful!

High flow to the max!

@Cairo94507 Michael - I'm still thinking about that. There's a possibility of splitting the bumper intake and running a false floor with an oil cooler venting through the floor louvers and the radiator venting out the fenders. I need to get the actual radiator I'll be running and work out if there's enough space to pull it off.
If not, I'll need to see if leaving the floor as is (for extra radiator venting) is a good idea or not.

[Chris914n6]

Exit holes only need to be 20% larger to accommodate the freshly heated air.

If you are going to cut holes into the wheel wells, which is ideal, then fill in the floor, which leads to rear end lift.

Also, I'd never run oil lines all the way to the front of the car. Get an oil-water cooler or a plain air-oil cooler and duct some air to it near the engine bay. Your engine isn't oil cooled so it's not vital like a big -6.
I only installed an oil cooler due to the lack of airflow compared to when it was a front mounted engine, and I needed a remote filter mount anyways. The stock cooler for my 3.5 is just an oil-water oil filter extension.

5 minutes of interesting build info crammed into a 28 minute video! (IMG:style_emoticons/default/av-943.gif)

[technicalninja]

Thank you for 30 minutes of cool!

The mufflers arn't...

Those are modified glass packs!

It's NOT going to be quiet!

You can freaking see through them!

Might even get flames...


The radiator ducting is awesome!

And you have shitloads of room for a condenser...

A BIG one!

I'd build it out of something that has less heat transfer than aluminum.

I built a really tight aluminum block off "box" (air filter) for one of the Miatas.

I completely sealed the air filter from the engine compartment and fed the housing from clean frontal air. Worked great!

After a 15-minute drive you could BURN your hands on the air filter side of the aluminum.

Had to go back in with some of the gold foil on the engine side which helped but didn't completely solve the heat transfer.

Had I made it out of stainless or better yet, plastic, it would have worked better...


You're lucky on the midget NASCAR. The track needs to be an oval which is a bunch easier to build than the 917 shown.

I'd bet there are BUNCHES of NASCAR themed slot car too...


And then there were the DEMONS!

My favorite part.

Very telling that you DIDN"T open the door! (IMG:style_emoticons/default/av-943.gif) (IMG:style_emoticons/default/av-943.gif) (IMG:style_emoticons/default/av-943.gif)

Man, Chris just never ceases to amaze. I love the mock-up for the radiator cooling system. I have to agree with technicalninja, that exhaust system should be pretty loud, but it does look bitchin' from the rear. It sits nice and high. Are you going to run some sort of rear valance? A shortie?

[tygaboy]

@technicalninja @Cairo94507 - That style muffler is the same as I'm running on my LS car and they aren't that loud. Granted, those are Magnaflow and these are Borla but same-ish design.
I was contemplating a rear valance but I REALLY like the view without one. We'll see.

[technicalninja]

Your cooling system ducting has energized me!

I'm going the water-cooled route as well and the basically circular tubes offer another option.

Get rid of the piss poor efficient flat fans on the radiator and place ducted fans near the outlets!

At first, I disliked dumping hot air over the brakes; on a race car this might be a poor choice.

On a streetcar with performance brake pads, it might help them not get cold soaked from in-activity, long stints at cruise.

Might be a BETTER choice to have slightly pre-heated pads...

This gets deep quickly and is applicable to using ducted fans as a thrust source, but the math is good, worth reading.

Here's a question about the V8 car. Did you ever notice excessive heat on the windshield/frontal sections of the car?
I'd expect the exits are far enough away that it wasn't a serious problem, but I'd like to know. The exit air is not stupid hot either.

Those stupid ass "exhaust through hood cars" will MELT the inner layer of goo between the dual pane front windshield.
While turbos prefer NO exhaust the rest of the car doesn't...

If you do a valence I'd make at least the center section out of mesh. You've had a couple of good examples hit this thread already

The "Ferrari" on the ass end of the transmission needs to SHOW right up to the point the Ferrari attorneys bitch about it.

At that point they need to be modified into "REDBARN" keeping the "font and style" identical. (IMG:style_emoticons/default/devil.gif)

I would add a tiny little LED to light that puppy UP at night...
If I did that I'd used a LED that had the ability to change color.
Imagine the letters mirror polished, on the jet-black housing, glowing RED!

Version 1 of the header-to-muffler tube. I don't know... (IMG:style_emoticons/default/dry.gif)

[tygaboy]

Actually, I do know! I slept on the Version 1 design and decided it's a no. The s-bend doesn't relate to any othe shapes in the engine bay (plus it's fiddly to make).

So here's V2. Better IMO because:
- more cohesive w/the rest of the shapes
- moves the exhaust tips in-board, which I like better (I cheated the muffler tip fixture to the right so pay no attention to the location of the right side opening)

[SirAndy]

So here's V2

Mine too.... The muffler should be parallel to the transmission. I prefer version one.

yup

[technicalninja]

I LIKE #2!

Much straighter tubes, easier fab.

Now, I DO agree with the others as well. Where the exhaust tips exit should be parallel with each other.

Not pointed in like a cross-eyed Siamese cat!

Besides the tips no one will ever see the angle of the mufflers except you guys who have been able to see "under the skirt" from the start...

[technicalninja]

It also aligns the exhaust tip exit with the license plate depression in the bumper.

You guys need to give me a little more credit. The exhaust tips will curve right off the mufflers. They'll exit straight out the back.

[saladin]

@tygaboy for kicks and giggles...and if I remember correctly you stated the muffler was reversible...why not reverse them to align the muffler with the trans and the header to muffler pipe more closely matching the angle of the lower trans support bar like the below photo...or flip the exit further out with the other mockup trans muffler mount bracket...
