Re: Early Pictures of Paolo Catesllano\'s DIY TT for Gen II Cars
Are the turbo's located under what appears to be heat reflextive material???
Simms, the compressor inlets are directly below the airbox. The exhaust(turbine housings) are under the heat shielding.
im no TT expert but those foil wrapped things look horrible. Or is it my untrained eyes ? ? ?
and a little powdercoating would help.
Plumcrazy, That is a certain type of heat shield wrapping that keeps the heat in the pipes feeding the exhaust gases into the turbos.
It is largely a matter of personal preference as to what is visually appealing. Some people like the futuristic silver space program-looking heat blankets and some do not. I can understand your thinking it looks funny to have aluminum foil all over everything, but maybe a personal viewing would give you a better look to really see it and how it works.
Thermodynamically, the kinetic energy of the heat retained inside the pipes by the heat shielding assists the gas flow to spool the turbos.
The turbo heat shields keeping the heat INSIDE of the pipes(from radiating outwards) Helps minimize radiant heat transfer that can heat soak the engine compartment.
I can tell you my car's engine compartment with all the heat shielding was actually cooler than when it was stock form.
The heat shielding blankets/wrap does a much better job than the ceramic coatings mainly because it is much thicker than the .005-.015 thicknesses of the ceramic coatings with which I am familiar.
The other benefit of the heat blankets and wraps is the fact that there is an air gap between the actual pipe and the insulation material which allows for better heat retention.
Air is an excellent insulator aiding to keep in the heat.
That is just some heat shielding I had laying around from my project. It will not necessarily be the final choice for what we use for every bolt-on system.
We might do something different all together.
I just posted some pictures as a courtesy for some potential customers who asked.
Please keep in mind this is by no means the final product.
I have not yet gotten a chance to mirror polish or powdercoat the compressor housings. It will be done according to the specifications required by the customer.
I can assure you the finished product will be very impressive and clean looking when you open the hood.
