Questionnaire on the future of turbochargers
Hello everyone
I am currently doing a degree course in Motorsport Engineering at University of Bath and am researching topics for my dissertation which is on The Future of Turbochargers.
Below is a link to the questionnaire that I’ve created and its purpose is to help me understand what motor vehicle/motorsport enthusiasts’ opinions are on the subject.
It would be of great help to me if you were to take less than 5 minutes of your time to fill it out. It is made up of just 10 questions, mostly of the multiple choice type. The questionnaire is designed for anyone from a regular car enthusiast to experienced race mechanics/engineers.

Thank you all in advance and have fun!

Done. Enjoy the age range question. 40 and over is a BIG group! 
Good questions. Turbo is the future...

Something your survey did not touch upon is that forced induction coupled with direct injection can yield significant power, fuel mileage, and reliability. The best of all worlds. For example: Mazda Skyactive, Ford Ecobost, GM SIDI, Audi FSI, and Porsche DFI are all examples where the major manufacturers are moving towards this newer technology.

Internal combustion engines are a dead end, simply based on thermodynamic efficiency.
Forced injection/induction merely speeds up your path to the dead end.
It seems pointless to spend large amounts of time and resources continuing to develop the ICE, rather than a new technology that doesn't have the fundamental limitations.

Completed the survey. I was formerly business manager of McLaren Engines and after we got our butts kicked by the Penske Porsche 917 in Can-Am, GM gave us a contract to develop a turbo 430 c.i. Chevrolet Reynolds block. Twin Garret turbos netted 1200 HP as compared to 750 HP with a 452 c.i. NA motor. The Hewland gearbox was not strong enough nor was the M20 chassis. No money was available for further development.

This is the logical place to post, since the 3-liter 930 Turbo was one of the first supercars, even production cars, in the US market to be made available with this technology. Saab also offered the 99 Turbo, but there really weren't very many commercially available turbo passenger cars at all when I started working on cars for a living in 1980.
I started in the early 1980's installing BAE Turbo kits on Ferrari 308's and, of course as a tax dodge, Ferrari built the 208 Turbo to take advantage of the tax laws that gave a discount for cars under 2-liters in Italy, at that time.
I installed Legend Industries turbo kits using the IHI RHB6 on Fiat Spiders at the dealership I worked at and Garrett AiResearch T04's on bigger stuff. We had a lot of trouble with people not warming up and cooling down the turbos, resulting in thermal problems that would cook seals and burn up impeller shaft bearings, so they went away.
Seems like its come full circle now in the quest for efficiency.
I will NEVER forget the first grey market, Euro Spec 3.0 liter 930 Turbo I drove after replacing the clutch in it. Moved my cheeks back, pushed my eyeballs back in my head and I was DAMNED glad the thing only had four speeds, 'cause I was moving the shift lever as fast as I could! Awesome...

Done. One note: the multiple choice questions likely should only allow one answer each (they're check boxes, which allow you to select all the answers for a given question).
Best of luck.
