I have done 175mph with my modified SC.
I have custom ram air that gets me about 4 to 5 lbs extra boost that climbs starting at 90 and seems to level off boost wise at about 120mph. Other mods might equal 275hp. Total could be 300hp with ram air. I have read a long time if I remember right that each pound of boost could be about 7 to 8hp.
I remember an old SCCOA magazine, vintage 10 years or more ago that I can't find that had the supercoupe running 205mph at Bonneville, holding some class record at the time. I can't find any info on this on the web. The picture of the car showed the engine compartment with intake mods, most likely a high flow exhaust was installed, however at that time I do not believe the engine could be modified with much more than 400hp.
I have had an argument now with someone, that supplies all sorts of comparisons and calculations, that this SC must have had at least 500hp.
My point is this, and it suddenly dawned on me. It is very unique to have a car stock with only 215hp go 160mph stock. Is there any other car that you can think of with as low horsepower going so fast? Gearing is not the biggest impediment to this type of speed, it is hp and aerodynamics.
Meanwhile I did find some info on the aerodynamics of the SC. Sorry to copy all this but I cannot find the website I got this from. Note the coefficient of drag has to be multiplied by the frontal area to get the real total force that the car encounters when in the wind.
The SC may actually be better than this, that is one of my questions. If this is taken with a standard body, the SC ground effects should make it better.
The other question is, if it is true that the mods at the time would have given this car at most 400hp, was the secret ram air?
