Hello Tom,
Long time lurker, first time posting, after joining today.
Have been following this thread for a few years, now.
Felt compelled to post.
Thank you ! Thank you ! Thank you !
Like a number of other folks on this thread, I read and re-read and read over and over again Gray Baskerville's prose on this awesome car. I cannot thank you enough for putting this car back to rights and doing it as it was originally.
I grew up in Dearborn with a backyard right next to Telegraph Road and the stop light on Cherry Hill was about a half-mile north of us. On Saturday nights, we could hear the racers shut down from departing that light, before getting to the Michigan Ave. overpass.
I had the good fortune to go out to the (old Gapp &) Roush shop on Levan Road, back in the very early 80s. A very nice fellow there spent a lot of time with me as I was interested in a small block to shove in a Capri (remember seeing a price list for a basic road-race Boss 302 at "only" $20K - too much for me at that time and now...) and when I mentioned SD, he kindly took me out to a garage in the back...
Shoved off to one side and covered with a good bit of dust was SD !
Since the hood was off, at first, I did not recognize it. It had the turbo set-up you referred to early on in this thread. However, it did not look like what was in the photos earlier in this thread. Above the carb was not the small inlet with blow-off, but rather a very large aluminum plenum that could best be described as a very large air filter but with the sides all closed off. At the moment, I do not recall if it was single or dual turbo, but I am thinking it was a dual set-up, especially considering the size of the plenum. Remember, this was the much earlier days of turbocharging and there was a lot of experimenting. Regardless, this big aluminum plenum was so large that I remember there was a section cut out of the cowl as it interfered. This might explain why you found the original cowl modification had been "altered" (to put it nicely).
I asked why it was just sitting there (this was before I read about SD2) and he explained that with the turbos (I do think it was dual), when the boost came in, the front end came off the ground (remember, this car was used from a roll, not a dead dig). So, imagine nailing it at significant speed and then the front end comes up and the car is uncontrollable...
That might explain SD2 and the NOS system they used instead.
Well, rambled enough I guess. Thanks for reading this far.
Again, can't thank you enough for saving this piece of history and bringing it back so beautifully.
