Turbochargers work off of waste heat energy, keeping as much heat as possible in makes them more efficient (until material failure obviously).

Your supercharge doesn't run off of waste heat, however compressing air produces heat as a by product, that heat is shed through the intercooler, supercharger body, etc. Basically you want to remove that heat as fast as possible. By heat wrapping your supercharger you'd be insulating it and effectively be heating the air faster and keeping it hotter.

Also I would spend more money on good ducting then vented hoods, etc. Any extraction hood needs to be properly designed to put pressure zones where it will actually pull out of the engine bay. Many of the "style" vented hoods actually adversely effect cooling. However a car like Cody's with giant turbo in cramped bay with all manner of important things near it would benefit from a vented hood just idling/slow moving traffic because all the heat could rise out rather then be trapped. However ducting its definitely the way to go an Cody's car will be getting that sorted as soon as all the bugs are worked out.

An example of effective ducting is my car. I removed the splash tray 3 years ago, it still cooled fine, no biggie. However now my A/C works again. At 80degrees ambient I can cruise the highway with A/C on fan speed 1. Above that it triggers a warning light for overheating because the cooling system can't handle the additional load. If I were to throw my undertray back on though it would most likely be fine because more air would be forced though the radiators.

TL;DR Heat wrapping a supercharger is a waste of time.
Edit: I also really enjoyed my Thermo class.

And Boom goes the knowledge bomb.

Do you have any data on the pressure zones with the 370z?
Asking more as a point of, no one does and knowing the actual areas and working around them will help everyone on cooling. As of right now we have no data and what aftermarket hood will or won't work efficiently.

With Pat's engineering/fabrication background and me with the wallet, car, and extra hands for helping everything is possible on this car at this point. Pretty much all of the things people want to see but no shop bothers to attempt will be done to my car....diffusers, solid underbodies, vented hoods, custom forced fresh air/heat ducts.

But no as of right now that isn't something we have.

I personally don't. You can always do the yarn test.

I have been trying to research the 350z, obviously similar design of course, and see if there are any details but no one really seems to dig deep into into.

I am picking up a Seibon TS hood in a couple weeks, though I have to get it repainted, I will see if I can acquire some stuff to test between the two hoods.
I plan to do some basic cipher logs on the car, engine oil temp, air temp, water temp, speed, rpm, etc to get a baseline for my car now.

This is one of the more informative articles I have been able to find.
AutoSpeed - Undertrays, Spoiler & Bonnet Vents, Part 3

Long read but worth it for the data inside.

the hood I designed will be aerotested and refitted for maximum sucking power..

I did note that there was a temp difference of about 10° idling with the 2 center vents

That's nice!!! Maybe I will just let you do all the work developing it first :p :tiphat:

So they'll design it based on your mouth...?? :rolleyes:


:inoutroflpuke: :bowrofl:

<3

no no no, this was designed following FP... im not very good at the suckin :bowrofl::bowrofl::bowrofl:

Your photochops say otherwise... :ohsnap1:



:bowrofl: :inoutroflpuke: <3


Get that hood done s0n!

:bowrofl::bowrofl::bowrofl: oh lawd! you had me in tears!

This is why I bought vented fender liners :3
Thanks - just wanted to be sure. I worry an awful lot.
