Supercharger charge pipe question

[Ashikabi]

Hey guys. I'm curious about the effect of charge pipe length on supercharger(specifically centrifugal). Most if not all kits currently come with a front mount intercooler. But what if someone used a liquid to air intercooler? Assuming you could find one that would fit between the throttle body and your supercharger outlet of course. Would the elimination of charge piping running thru the bumper increase throttle response? Decrease charge temp? Thoughts?

Ps: I am aware it's easier to just buy a kit and use what they give you but I'm curious about this.

sprintex's and other twin screw supercharger kits use Liquid to Air intercoolers. necessity varies depending on your supercharger of choice.

since most of the rotrex and centrifugal kits work like a belt driven turbo, it is more effective for these kits to run an Air to Air intercooler, which works most efficiently with heat radiating off it.

You'll still need some air going to it. Look up the last gen celica all tracks. They have a top mounted water to air inner cooler. But it has a hood scoop.

To me it's extra work for a bit of gain. More stuff to go bad. But if anything it could be done, lower air temps and what nots. Not sure how much power you'll gain but some one out there might find out.

I was thinking more for the reduction in charge piping. Would that affect how quickly boost is delivered since there is less pipe to pressurize?

I assumed that was understood.

It takes almost no time to pressurize the pipe and IC. I went from a TMIC to a FMIC on my WRX and it really made almost no difference. The on/off throttle response was still very good even with the larger FMIC and it used longer and larger piping than what you have with a S/C on this car.

This is the kind of info I'm looking for. Thank you

Supercharging by design is instant. Pretty much by the first crack rotation it's up and ready. Doesn't really matter how long the inner cooler pipe is. It would stay in vacuum after the first time you turn the car on.

Turbocharged that's a different story. I'm thing your mixing your forced inductions. No worries I been there. Both of my old cars gets me thinking at times

He's talking mainly about centrifugal superchargers which are belt-driven turbos, for lack of a better description. They generate boost faster than a turbo since they aren't exhaust driven, but still need to pressurize a charge pipe and IC.

The thing is on or off throttle at a given rpm the SC is flowing the same CFM. The variable is the bypass valve so really throttle response won't be changed with charge pipe length, only BPV responsiveness will play into throttle response since all the airflow is already being pushed back against the throttle body and out the BPV.


Disclaimer: I could be wrong and if someone points it out to me I am ready to learn!

????????
Uh. Supercharge... Boost is instant. No mater what version. Roots type or centrifugal.

Interesting fact one of the later ford lighting trucks played around with using the AC to cool the inner cooler. Cool idea but extra load and worse mpg for a daily driver.
