I think its the scale of both graphs. Are you sure that is a base dyno? hahah look the base is making more then the dyno sheet on the intake. However, The AFE intake dyno is under 210. while the base is over 210 in both runs. HAHAH I have never seen a G make under 200lbs of torque. Its got to be a fake dyno LOL. I just didn't look at the numbers on the side of the dyno I was just comparing the lines in gains. But the idea of having a straight pipe with no interruptions restrictions sounds like a more efficient way of sending air through the intake.

 

when I was a kid I used work at my uncles shop and he used to restore classic muscle cars. I remember some of them polishing the inside of their piping and manifolds, throttle bodies, to a almost chrome smooth finish to help the travel of air faster to the its point. Hence, the name Port and Polish. the grooves of the natural unpolished pipe surprisingly slowed the air down. I remember I used to see a big gain just from the polishing of the intake ports and piping on the dyno. Has anyone polished the inside of their intake mani ports , and throttle bodies here?

 

the fact that it's lower doesn't really mean anything because it depends on the dyno used. My guess is they took the lowest stock dyno they had and used the highest "after intake" dyno and put them on top of each other to make it seem like it gained that much.

it may be the scale like i said, but something still doesn't look right

 

yea your right it does look that way.

 

^ not true.. our intakes are designed the way they are to help air flow.. A more agressive situation would be the Honda Engines.. if you take apart their air housing you'll see little channels everywhere for air to travel around. This works with the pulsation of the valves opening and closing. Or to simply say it you will never find a RSX increase horsepower with an aftermarket air intake. I can tell you this for sure because I've spoken with a engy for Honda and we've dynoed tested back and fourth between an RSX-S... Yes I know this a RSX and we drive G35s but thats just an example of why we have the weird tunnels and stuff in our intake. Our VQ motor doesnt loose any performace by switching to an aftermarket cone nor by removing resonators but it doesnt help it either.. I mean think about it.. The amount of air that is pumped through our motor at WOT in upper RPMs do you think a slight change in the shape of tubbing will increase anything? it'll be like sucking air through a normal straw vs a L shape straw of the same diameter..

In the end you can probably get a HP increase by swaping to a cone filter with the hood popped and a dyno fan blowing against it.. but If you ever dyno an aftermarket intake using:
Within the same day
Same tank of gas
WITH THE HOOD CLOSED
Same condition (1 Burn run and using the 3rd final pull as compairson)

You wont see any gains.. but you may see a loss.

Aftermarket intakes = for the sound and the ability to clean and re-use the filter

As for the Dyno used.. You can do that by compairing lets say the 5th pull to the 1st pull..

EDIT: in the end I like the design of the air box. It'll probably make a good intake and wont get heat soaked like some of the other aftermarket intakes. The Mass Air Sensor will go between the tube and the shield.. overall looks pretty cool and props to the company but whoever buys it please comment on quality and material used. but boo on the dyno tho [but hey you gotta sell some how]

That's what I thought, I just didn't want to make a$$ of myself, if I was wrong like before on a other thread.

 

I thought mirror finishing the inside of the intake and ports increases the velocity of air to the motor? I thought the key to performance was the elimination of the air resistance to the motor. So Polishing intake runners and gaining velocity for performance gains is just a figment of a tuners imagination?

 

looks like a nice intake. definatley something i thought i would have seen already. the only thing i see that's odd besides that dyno is that if the diameter of that intake tube where the maf sits is different from the stock maf bore, it may cause some issues. MAY. not really sure but i believe ive heard some performance junkies talking about the negative effects of that happening. overall looks good though, if i didnt have the stillen id buy it.

 

I would just do Ztube and PopCharger

 

electric tape ftmfw

 

That's not a VQ35 dyno. I call BS.

 

I'm starting another thread about a theory please chime in. Teflon coating intake s?

 

I think thats grease I don't see any tape.

 

my thoughts exactly.
