Turbo 2.8 with the intercooler housed in the spoiler? (Page 1/1)

Not sure if this has been discussed before (I'm sure it has at some point), but has anyone seen this turbo Fiero with the intercooler housed in the spoiler? It's the second car in the video, at about 51 seconds. Very interesting!

That was a prototype car. There was some debate whether there was enough airflow to actually make use of the intercooler.

This car was originally called the Porsche Eater. It was built along with a Black car in 1984/85.

It originally was a GT coupe and had a 2.9 Turbo Engine in the car.

Not sure what engine is in the car today. This car has seen a number of changes over the years.

The black car is still around pad in a museum in Northern Europe. It is still a coupe but it was given the DGP body kit with the GT wing. It retains this look from 1985. I believe the 2.9 was removed for other show cars.

Both cars were called Porsche Eaters due to the powerful 2.9 engines and the tail lamps that would light up saying Porsche Eater in the lens.

The air flow here I expect was more than enough as these turbo systems are based on much older low flow and pressure systems. They are not like today’s systems that are pulling mega boost and flow.

To do a modern system with high boost you would need more air and fuel. My 2.0 DI system was pulling 23 PSI on pump gas. Today’s systems are using Direct injection that helps cool the cylinder to cut down preignition. Same with better oiling. These old systems were very limited in boost, power and durability.

I have seen a couple modern turbo systems in the Fiero and the owners used the trunk to better suit the modern systems they use. Larger tubes and larger coolers. Also better air flow ducting and fans.

Interesting stuff for sure! The more I learn about them, the more I love them. Such an incredibly versatile car.

Where is this car now, GM collection?

The red car is still in the GM collection.

IMO, the system is a novel design but highly impractical. When you close the deck lid you have two flexible hoses dangling near or on the exhaust. Fire hazard, maybe? Also those long tubes in the engine compartment can really get hot negating the function of the intercooler. The system looks nice for a prototype show car but that might be it.

Hard to say how much hazard if it is high temp hose or not. It has never burned and the car in the past did get driven.

Also this was a car built in the late 80’s. Much has changed since then in Turbo tech. Things were no where as effective, efficient or durable. We had just seen the first water cooled turbochargers on the GN a few years before.

The greater issue is the lack of air flow. Not much air travel to the spoiler anyways.
I recall driving in the winter and the snow would remain on the spoiler accept for the ends where the vent heat blew over it.

Yeah it was really the novelty of it that caught my interest. Practicality may not be there but I thought it was a unique and interesting design.
