A kind gentlemen - who is not big dogs, or affiliated with them sent me a big dogs cobra intake that has been ported. I’ll be replacing the box r intake on the car temporarily to see the difference.

I won’t get into the pissing contest, really here as a third party to make a comparison. Here are some pics of it compared to a factory explorer intake. All measurements are in mm.

This will be a strict a to b comparison deal. I’ll look at fuel flow and dragy times to see which one works the best. Engine is a woody built 347 with a f1r blower. Any ideas on which will come out on top?

If anyone wants any other pics or measurements, please Let me know and I’ll oblige if I can.

Looks awesome. What was the motivation in staying with a Cobra intake vs going aftermarket?

The box r will eventually be going back on. This is just to do some testing.

It’ll be interesting to see how the lower matches up to your heads.
I think it will be a bit smaller judging by the 1262r on there now.
Looks nice, can't wait to see the results.

is this the cut and welded upper?

Lower looks huge, which heads are you running?
I believe it’s just welded on a couple runners to allow for more room to port.

They’re 11r 205s

I've always been curious about numbers on the intakes. I have no desire to partake in the pissing matches.

WHat exactly is the test you are going to do? Stock explorer lower and upper, vs the BD cobra upper and lower?

Tech is good, but the upside readings are killing me lol
Lmao. I’ll upload them again and flip them.
this is the cut or uncut upper?

where are you located, i have a R long upper you can try and a systemax. might even have a tmoss lower to compare too.
I believe it’s uncut. What size opening on the long r?

I’m going to see how the cobra intake does against the box r.
Actual measurements are nice, but we need sockets per square inch of port volume to get accurate information.
Hold on I’ll stick a couple sockets in and get back to you :LOL:

I was always told by the best it's not sockets, it's golf balls. "Oh yeah this is ported so great you can roll a golf ball down the port.
