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.

just curious why measured in mm... canada? or some other county thats non SAE?

wouldnt it be more useful to do measurements in inches in a case like this in 'Merica?

I wanted to spice it up a little bit.
LMAO i hear ya... well i'm not sure of the conversion... but i think by my calculations either you can fit a small child in there... or a few single celled organisms... possibly the reality is somewhere in between.. good luck with the test...

p.s. whats the metric equivalent for one HORSEPOER.. like 3.2 goats?

Lol. The "Metric Horsepower"

1 HP = 1.01 Metric Horsepower. o_O

1 Horsepower lifts 550 pounds 1 foot high in 1 second

1 metric horsepower lifts 75 Kg, 1 meter high in 1 second
