"shorter intake track"
hi there guys,
i was just wandering as far as more performance per haps would you gain any hp or rpms/better throttle responce from making the air filter duct shorter?
as in i mean instead of the stanard long air filter base/duct where it is and as long as it is ,how about putting a conical filter on a shorter duct and then connect it to throttle body!
for instance when i used to be into goped motorised two stroke race scooters we used to lenghten the intake tract/manifold which gave the motor a little more torque so i am thinking now the corvette has such a long complete air filter tract that if you were to shorten it and have conical filter closer to the throttle body that they may give more rpm or may be quicker throttle responce may be?
the only down fall i can think of is though the filter is going to suck in more engine bay heat though as it is closer to engine/manifoid isnt it?
what do you think guys please?
thanks

hi andrew,
thanks for the reply mate!
just a thought anyway!
i noticed the "ram jet 502 chev" comes with a short conical filter instaled to the throttle body thats all!
it had no long intake system on it so was just thinking some!thanks for your input mate!

I believe your thoughts are correct. A filter on a short duct will suck better than one on a long duct with bends in it. However, in the case of the vette, what little you would gain with a short duct will be more than lost due to engine heat. Temp is way more important a factor than length of duct.

hi hot red 94,
thanks for the reply!
i am running 8"hood cut naca ducts and hood rear vents as well for the hot air to escape along with the a/o engineering forced air number plate coupler/duct also!
so there fore the engine bay is alot cooler than normal!
also i was thinking of adding a deflector shileld around the bottom of conical filter to deflect away heat as well!
would things be better/different now with these extras?
thanks

On the subject of engine heat in that area of the TB...
Speculation doesn't work in the real world.
How about some real world tests while running down a track or something where the car is moving forward and the hot air is flowing away from the intake and tb?
I would also think that more air, even if warmer from the engine heat, would be worth a lot more than cooler air being sucked through the tiny straw of an intake box.

"On the subject of engine heat in that area of the TB...

I left a tool sitting on the radiator shroud and part of it was sticking over into the air that the fan blows, it was so super hot that I almost dropped it. That's what would be blowing into the TB. Put your hand in front of the cone and see how hot it is. With the fan off there will still be heated air there when the car is moving.
"I would also think that more air, even if warmer from the engine heat, would be worth a lot more than cooler air being sucked through the tiny straw of an intake box."
The air intake flows more air then the engine needs so it makes no difference. That tiny straw feeds more then enough. Does everyone with a larger displacement engine change out the air intake?

I made 378HP (408cid) to the rear wheels on my 85 through a dirty K&N, stock airbox and MAF sensor in place.

Who is pulling better numbers with a non stock intake? Being intrested in gaining power, I always read those topics and don't remember any. Here are a few I know showing stock is fine:

If a ZR1 gets enough air, the L98 will. It's just dyno results of non stock air intakes. It applies to the L98. If you search more you can find other topics with dyno results on the L98, I just remember those links well.

Obviously the best solution is to improve both areas--more and cooler air. What about putting the air filter on the MAF building a full shield around it, then running cool air ducts into the shielding from the outside? I've always thought that was the best solution, I just haven't found a convenient cold air source yet.

For reference on the A/O intake the above link talks about the maker, I have one on my car. I wanted it for looks.
