dual side mount...good or worthless?

[s13silady]

Hey guys.. recently i met a guy with a fastback s13 with an s15 front with sr... he's running a dual side mount intercooler setup... one connected to the throttle body and the other obviously to the turbo...he says his idle is close to perfect with no stumbling... you can hear it too...

well i was just wondering, if there was any point to doing this or if it was just for show or for function? what are some drawbacks for doing this as well as good points to doing it?

what do you guys think?

i wouldn't think it'd be much for show seeing as how using two sidemounts would be more discreet than a FMIC.

this would be good for you cali boys that get harped on by johnny law so much.

[s13silady]

yes it is a little more discreet... but would it be functional enough to makke a GOOD difference?

and yes we do get shafted with law...it sucks...

If its one intercooler per side, like reonator area driverside/passenger side, then its A LOT of wasted piping, ... unless hes running <2" I/C piping the lag would be retarded. every 90 degree bend is like 4 feet of straight pipe right?

well the more cooling the better so i'm sure yes it would be good...if i understand correctly you're saying the charge after the turbo goes:

turbo=>stock SMIC location=>SMIC on opposite side=>intake manifold?

[einherjar]

Wasted piping!!! ... i'm done.

[Ian]

well wouldnt it still cool better regardless of the fact that he has enough piping to plumb a condo?

wasted piping fix:

worm holes

you can thank me later.

[Ian]

yea i got those in the welds in my piping...


oh wait i have "pin" holes due to poor welding :(

lol, it would cool ohkay, but a FMIC would be much more efficent because the total surface area touching the air would be probably the same but FMIC is in direct air flow, and is less piping. My I/C setup (work in progress) is top/side, i have half as much piping/bends; and with stock wastegate i'm boosting 9psi instead of the usual 7psi, barely any lag its great, so pipe length does make a difference.

[s13silady]

well the amount of piping he had in his car looked exactly like a front mount...but it went to 2 seperate intercoolers.

[AKADriver]

So he's basically replicated the setup used by VW for the Audi TT 225hp model? That car has one SMIC in each fenderwell and a pipe that connects them running under the bumper.

It's not a bad idea at all, though if he's using stock SMICs that would seem a bit restrictive. It'd cool VERY well, though.

When doing a dual I/C setup you always do it in parallel, not in series. There's too much pressure drop running I/C's in series.

Personally I think running dual I/C's is a waste of time. If I were to do someting custom like that I might as well go V-Mount (if I'm doing it to go low pro).

[mrmephistopheles]

waste of time.

psssssssssssssh. worm holes?

i'm talkin speed holes

[MakotoS13]

OKAY, wormholes as in a physical impossiblity, not an actual HOLE.

haha
