Beautiful engine bay, love the diamond plate cowl replacing the cardboard original. I am facing a header install when my '80 engine comes back from shop, thanks for succinct tutorial
@@stephennickles7389 thanks. The diamond plate was pretty easy to make. Here is a video on how I did it ruclips.net/video/zK_f5skMUoE/видео.htmlsi=F1-tgIY8-Jx2934T
Vert clean! Thanks a lot. Did you build heat shield yourself? Have a plan of an upgrade on my '72, with Weber 32/36 and a friend looking for almost sane setup as yours with dcoe45.
I understand your perspective... But, I initially tried Stainless, and it turned out the heat transfer was not "radiant" but transferred through the head back into the intake manifold. Also, I have thermal barrier on the back of that Aluminum sheet. The idea of that was to increase the surface area to allow the heat that was being transferred to be dissipated prior to being transferred to the carb. here is the video of the stainless attempt ruclips.net/video/BihaJZrMMZA/видео.html
The point I'm trying to make is you've boxed in the engine bay so you've removed a massive amount of air flow from the engine compartment. As you stated your car isn't in a high state of tune and therefore not creating additional heat it seems rather odd you're having to completely reinvent something that has worked fine for years for just about everyone else.
@malcolmlane-ley2044 well, this setup is far from stock. It was a barn find that had a blown head gasket and had suffered from overheating. It had a burned exhaust valve, and a oil ring had rolled. So it had this issue a long time ago. I am just trying to resolve it so I don't burn up the engine as it had done before. Your point is well taken. But since this 1977, 18v type has a 1974 head with the large intake valves, and a Kent fast road cam installed. Not to mention the Weber dcoe 45 carb. (A larger than usual carb) The heat issues are not because of air flow in the compartment, but rather other heat sources.
@malcolmlane-ley2044 I re-read your comment a few times. And I believe I have figured out your perspective. You may be referring to the diamond plate mud plate below the radiator. If your model is an older you may have a fan mounted on the front of your water pump. On the '77 it has electric fans mounted in front of the radiator. In the place where I put the diamond plate, there was a cardboard and tar mud plate. Mine had deteriorated so I replaced it with the aluminum. I have a video on that. Sorry for any confusion

Nice and clean install…I like it!

@yannbarraud4767 yeah the heat shield was developed over a few tries at preventing vapor lock. I also made bakelite phenolic spacers
Here was my first attempt

This is the one that worked

@@AlexPlatacis thanks a lot! No pattern or measurments by any chance?
@@yannbarraud4767 I try will do a follow up video later today. The bolt pattern will vary based on your manifold, and Carb.
Where did you get the EGA badgeforyour MGB grill?
My wife gave me that for Christmas or birthday...
She probably found it online idk. I will ask....
I'm rather surprised you're complaining about too much heat when you've enclosed the engine bay with aluminium sheet.
