This now has me wondering how well a BLAT Eagle run by AAR could have done with a 935 motor instead of their small-block Chevy.
OMG.... ![:confused:](https://forums.autosport.com/public/style_emoticons/default/confused.gif)
I've had terrible discussions elswhere within this forum about this car because o......
OK, at the risk of yet another provocation of our self proclaimed aero specialist over here of who I wonder if he ever had seen such a car to begin with....
I have seen the BLAT Eagles in real.
According the designers the car was not a ground effects car according the letter of the word and like the then current generation of wing cars.
Nevertheless: the BLAT Eagles did have a tiny air intake that fed the diffuser that was created by the floor of the car.
Thus: the floor of the car was raised upwards a bit.
And believe me, the diffuser at the rear of this floor had quite a steep sloping upward profile.
The exhaust system of the engine would likely have been compromised in the same manner as we saw in later years with the Porsche 956 and 962. Not in the least because the Indy Flat-6 only had water cooled cylinder heads, the crankcase was still aircooled and this airflow had to be disposed as well through the car.
The basic 935 engine like the one you suggest was fully aircooled and had even more air to dispose,
Then, the Flat-6 was wide. And when fitted with the Chevy V8, the cars has radiators at fuel cel level, ahead of the engine. Such was possible due to the width of the V8.
My guess is that had the wider Flat-6 being used, the airflow through what was the equivalent of the Side-pod would have been compromised quite a bit. Probably making a relocation of the radiators more forward necessary. And how that would have affected the basic design and principle of the BLAT concept.
All together: A Porsche Flat-6 engine in the Eagle would have made it an entirely different car then as we know it and wonder how such a modified variant could have worked as well as it did with the Chevy. and could have worked with contemporary V8's in the basic design as we know it.
But having said all of that, I really wonder how the car that was designed around the Flat-6 (the 1981 Interscope `Batmobile`) would have had performed with that engine.
