Post subject: Fiero rear trunk removal  PostPosted: Jun 20, 2016 - 05:53 PM

My Diablo 60 is based on a 87 Fiero (fully complete and running) except the trunk is still fully there.
It has a 350 with a engine cover on top. One Rad in the front. The engine bay is getting very hot.....
I was thinking of removing the trunk and putting fans in the rear to circulate the air. Has any one removed the trunk with the body already permanently mounted. What would be the best way to remove the trunk? What about building a brace frame and welding it in place? Any other Ideas to reduce the heat in the engine bay?
Any and all advise is greatly appreciated

Thanks
CCIE

CCIE,
I have IFG coupe with American Supercar chassis with 350 engine.
I have dual radiators on engine and it doesn't overheat, but I installed dual fans that are temperature controlled to start up when engine bay temp reached 170 degrees F.
These fans can be removed and installed anytime I feel I may need them, like if weather is in the hundreds during the summer.
I have had my car idle for over an hour and never overheats.( that is without dual fans)
I do not have engine cover on engine.
But 2 fans on temperature control switch could help exhaust the heat.
You have the titanium diablo ray had on display in his shop at IFG?

Hi VT,

Yes I do, Unfortunately it was just a show car, I have been doing improvements slowly, It was built on a Fiero with just one upfront Rad. Belt driven water pump. The engine cover traps the heat in the engine bay and there is no circulation. I would love to drop dual Rads but its already complete. With the trunk in place the heat is trapped with no exhaust going out.
Would love to leave the engine cover in place without having to worry about it heating. Any ideas are greatly appreciated

CCIE

My IFG Diablo 60

This is an old pic
The engine bay is very dirty but you get the idea about the air flow

You could use fans like these to duct cooling air to your engine.

12vdc duct fans: http://www.mcmaster.com/#duct-fans/=12zcb6l

I am using two on my car that collect air from the rocker scoops, through flex hose ducting, through the fans and then to ducting around my exhaust over the transaxle and out the grill between the taillights.
You will still need to have an exit for the air but the air should find someplace to go.

RT...... Thank you for the reply!!!!!

I have purchase several ducted fans but as you said the air has to go out some how and the trunk is getting in the way. I thought about drilling 4 inch holes in the trunk and putting the tubes and fan (x2) and exit the air out the rear vent but the best solution would be to cut the trunk completely out and put some sort of steal to brace the body with. The issue is that with the body permanently mounted it looks really hard to cut out the trunk and weld bracing substructure in place. I was hoping some one has had to do this and had some advise for me!

I actually ran two fans to pull air out. See http://www.lambobuilder.com/after/index.htm

Dale....

Awesome Thank you.... In your build guide is that a replica Chaise or a Fiero.
If it is a Fiero is the trunk still there?
Is the air flow from the front vents to the engine bay then sucked to the bottom? Did you use any kind of ducting for the air flow from the front vents and any fans?

Thank You
CCIE

The 6.0 was on a NAERC chassis. My roadster was Fiero. The vent was simply to get airflow under the engine cover. The fans exhausted heat buildup.
On my Fiero Build, I removed the trunk. See http://www.lambobuilder.com/bodymount.html
I did fabricate a trunk later http://www.lambobuilder.com/decklids.html
