Thread: has anyone dynoed the different intake types?

OR

You run right off the throttle body, completely non-restrictive, no bends or anything, air getting pulled in is warm, blower heats up air anyway.

Thanks man, I think I'm gunna go this route then and sell my FWI.

Thats what i thought is it had some kind of reason for being there. So wouldnt being just ziptied out in the open give it improper readings? I would think it would need to be somehow incorporated into the actual airflow of the intake like normal to get proper readings allowing the engine to run optimally? Correct?

Ha right. Didn't think of it that way for some reason. Good point thanks for clarification.

no, it affects the timing tables. it doesnt really do all that much once you tune the car to run whatever timing you want though.

i had it zip tied right next to the cone filter, so it was probably getting damn near what the actual intake air was at.

Ah ok. i dont yet understand how all the sensors an stuff work. i can replace them an fix broken things and now build a 3800 but as far as tuning and exactly what all the sensors do and affect and what all their #s mean i have not yet learned. Hoping to in the future though.

I had mine zip tied for A LONG time...plus the fact when it is colder IMO it helps it being outside anyways. Maybe that is just me.

So just ziptie it onto the filter?

here is where mine was:



you can see it on the left hand side where the filter meets the throttle body.

I guess that's how I'll probably set it up then, thanks bio.

the IAC shouldnt create an SES unless its unplugged or gone because it melted on your headers.
