This looks a nice heat shield :)

Shame I dont have a Supra anymore, as this shield would have suited my setup nicely

I wonder if that would fit with a single...anyone?

Not sure about the single fitment but I have a polished brake fluid reservoir & relay cover from them and they are spot on, great fitment and superb finish!

I like the way they put the holes in it...................................to let the heat thru to the filter:search:

Looking at this picture:

It looks like the holes are there to allow air to come in from the stock top air feed?

That is just stupid

The air feed over the rad works on suction (same as the one under the headlight), no air is forced though it at all. In fact, the fan blows hot air right over the top of the "holes" in this "heat sheild", making it useless.

So isnt this basically the same design as the Blitz filter heat shield, but with an elonged lid with the holes? Also the Blitz shield is slightly angled on its lid too.

Also, please dont shoot me down on this, but I did notice that either side of the heatshield I had would get hot. Wouldnt the holes above also allow some of this heat to escape?

EFL stuff is usually good quality

That thing, although shiny, will do absolutely NOTHING useful at all. The air intake needs virtually hermetically sealing away from the engine compartment, so it can ONLY pull cold air from outside of it. You know, like Toyota did it with those oh so dull looking bits of black plastic.... You don't need to insulate the outside of the ducting, the surface area of a tube's walls in comparison with the volume of air passing through the duct and the time gas molecules stay in contact with the walls, makes lagging intake ducting pointless.

Makes sense, so what do you recommend we single owners should do?

I am going to try and make a cold air box for mine fed from one of the spotlight holes on my bomex, or you could mount the filter behind the bumper.

Cool. Looking forward to the results.

I got some aluminum heatsheild in order to make up an airbox for the car, however as we are trying to keep hot air away from the filter and not WATER, I always struggled to understand how we could do that without the box being air sealed.

I would try and modify a stock air box unless you have , or have access to, excellent tin bashing skills.

or have access to, excellent tin bashing skills.

you make me laugh...

Question - if one does modify the stock airbox; would the stock element have enough flow for a small single (T61).

Easily. I am using a stock air box on my RB26DETT Skyline engine, I did a pressure drop test on it today, when taking it for its MOT, and it was negligible. It's already making over 500 and should do an easy 600 HP. Given the build cost I can assure you that if I really thought it needed a trick air box I'd have probably gone the extra nine yards and made one. A LOT of stock stuff is fine unless you just can't resist shiny things

bugger....lets hope I havent binned the stock airbox.......
