R34 Twin Inter Cooler

[maddowse]

does anyone know if i can install a second intercooler on the drivers side of the car ?

i looks like there is room for it but figured if its been done someone here would know about it.

if it can be done can you please direct me to a link explaining

[R31Nismoid]

Why would you bother mate?

You then make the pipework even longer than the factory setup... little point in doing that.

It does look pretty awesome, but the extra piping will probably cause delay in the air being rushed into the intake manifold.

it does look awesome !!! so your saying there would be more power loss than gain ???

[daisu]

Doesn't look like that much extra piping. Especially when you consider some of the other alternatives like a turnflow frontmount on an RB20 or 25. Plenty of piping there.

I cant vouch for it, but theoretically speaking the air has more room and more distance to travel. It *could* cause delay. Due to the extra room in there, it *could* cause a drop in pressure as it will take more air to fill the chambers. Don't take what I say as facts, I'm not sure. Someone correct me.

OK when you say delay are you talking off the line drag racing delay (where .5 of a second counts)

because for cooler air i dont mind the slight delay if the end result is more power or punch if you know what i mean , i dont drag the thing its just fun to give it a squirt and i dont want a front mount , after all there is already an oil cooler and a radiator there so i figure use the available vacant space.

it would be good to hear if someones done it and verify what your saying ,

thanks for the advice if its may cause a huge delay and drop power i might think about leaving as it is

Well lets look at it like this, its a common practice to have two sidemounts. It wouldn't be done if there were no benefits. All benefits come with their losses. Bigger exhaust, less back pressure. Pod filter, heat intake. Bigger turbo, turbo lag etc.

But the gains are there. What I mean by delay, is the air has a longer distance to travel through all the intercooler piping before it gets to the piston housing. I don't think it would cause any performance issue once the air is fed through, but again I'm not too sure.

right i get you now

thanks for your help

so the other thing is if i were to do it could i use one off the left of another car and just flip it to fit the other side ?

You are going to have to consider the piping behind the bar. The water bottle for windscreen wipers and coolant are right behind the front RHS of the car. You could use another R34 sidemount and flip it so it mirrors the other intercooler.

You might have to use aftermarket cores (like the two above) if you intend to use two coolers.... If you run much more air volume than stock you will probably find a nasty flow restriction using two factory cores.... if your running stock boost (or close to it) with your stock turbo you should be allright.

You'll have to vent both coolers (air feed AND exit) well to give them any chance... maybe consider a water spray or thermo fans as well.

If you go with a foward facing plenum, it will reduce the overall length of the pipe work quite alot with this style set up.

If you do go with two cores, tap a boost guage into the charge pipe just after the turbo and one just before the throttle body... if you have more than 3/4 psi difference, it's to much or a restriction.

I'm not saying dont do it, but even if two cores arn't a flow restriction, they won't be as efficient and will heatsoak quicker compared to a larger fmic.

More effort, more cost (if you don't do the fabrication yourself) for less result???

At a guess it would at least be an extra 30cm, perhaps more because remember you still have to go back to the factory plenum and so on.

So going from turbo --> cooler --> across car --> cooler --> back across car --> upto plenum

Thats fairly long

That looks bloody madd!!!

Im going to take a guess as he is Melb, he is trying to avoid defects... so plenums and things will not really aid the situation.

If i'm right, the smarter way would just be a returnflow FMIC, stock airbox, problems all solved without much hassle.

For the ultimate stealth cooling... just install some 1000cc methanol injectors and pump straight methanol into it ha ha ha.... no coolers required!

Not exactily practical.... but stealthy.

lol yeah im in melbourne and wanna avoid the defects, cops here see so much and an led light and they will pull you over to give the car a once over.

see what i dont understand about the front mount wouldnt it be less affective as the air is heated twice before it hits the radiator (inter cooler then oil cooler then radiator) thats what i want to avoid you know it great to give more power but woulnt it make the car run hotter or has this already been explained before ?

sorry new to turbos !!!!

Front mounts work better in stop start traffic due to the airflow provided by the engine fan. To make side mounts cool well in traffic you would need to install thermos on them which sucks more power than you gain I would guess.

Heat soak may be confined to one intercooler which could help too.

well as i said im very new to it all and im sure youv all had this question a million times ,

i guess ill look around to getting a front mount some time in the future, iv got to change my front bumper first (i have a series 2) will a front mount hide nicely in a series 1 bumper or do i have to go a nismo bumper or something?

Ok so it's as i thought, legalities...

Just put a RETURN FLOW FMIC on... one that uses factory piping etc.

Stick to the factory airbox, then you are 100% legal in that regard with only one intake modification.

[(OO)SKYLINE(OO)]

^^ +1

Just go FMIC with return flow piping and leave air intake with the stock air box or upgrade the panel filter to a high flow one.
