Europa TCST
BDA:
That's what I remembered! Thanks for posting that, JB! I had forgotten is was done by Checkpoint America - I believe it was started by Dan Gurney.

Nice! I like the part "will out accelerate a Daytona Ferrari from 0 a 120 mph"!
CWTech did not use a kit , he did (or had made) all the parts he used.

My first challenge will be trying to get a jack under a Europa with four flat tires.....

As far as Checkpoint America, I don't believe Dan Gurney had any involvement. ...Back in 1974, when I spoke with them, it was owned by Bob (Vanderhoof) or (Vanderhoot). [CRS strikes again!] :headbanger:
The Checkpoint America conversion was not sold as a kit. ...Turbo installations had to be done by them. ...That is why I designed my own.
Checkpoint America used a Rajay turbo, which did have a seal on the suction side. ...Air Research also had a small turbo which used a seal on the suction side. ...At that time, it was very difficult to purchase a single turbo, as those companies wanted to deal on a larger scale.
Crane Cams (in Hollandale, Florida) was just getting into the turbo business and selling components. ...They were in process of developing kits, but that never progressed. ...I became a Crane distributor (long story) and was able to buy direct from them. ...They used Schwitzer turbos, which had a "piston-ring" type seal on the suction side, and were not good if subjected to high manifold vacuum.
The Schwitzer turbo was fine for a blow-thru (the carb) system, but weighing the pros & cons, I wanted a draw-thru system ...I incorporated a design to isolate the compressor side of the turbo from manifold vacuum, yet it could still "free-wheel" to reduce turbo lag.
Back then there was little information about turbocharging available. ...Many people that knew wouldn't talk, and many people that talked, didn't know! ...I learned a lot through trial & error.
