So I’ve got one of these big dogs porting intakes here…

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.

Some flow bench testing would be interesting to see if they coincide with what Big dogs says they flow.
Fyi, whoever quoted me is on ignore mode so I can't see anything they said nor am I interested in anything they said!
Only thin skin Karens like you use the ignore mode. Be a real man and take WHATEVER someone has to say to you!! It's just words and if words hurt your feelings that bad then you need to grow up some!

The restriction that's causing a slight increase in boost pressure is the Cobras lower 80mm throttle body tunnel flow vs the Box R higher 90mm throttle body tunnel flow NOT the individual runners flow which is expected for those that don't understand.
When flowing a intake manifolds runner you are flowing one runner at a time so the TB tunnel is not a restriction when doing it that way. When the the manifold is on a running engine you have multiple runners drawing air at the same time which puts more of a demand of flow from the TB tunnel. It's that simple for those that may not understand.
Damn........That's a Richard Holdener explanation if I ever heard one...😂

Just letting whoever just quoted me know you are on ignore mode so there is no need to quote or troll me because I can't see it anyway👍
Again......Nobody gives a fu$k about the ignore mode except thin skin Karens like you that call the feelings police any time they dont like what someone says to them. Totally immature to say the least and you expect people to respect you as a legitimate business man with the childish attitude you have.
