what is the biggest intercooler fitted to a VR4?

[CANDEE]

I have my crashbar spaced out 6mm and have no bumper fitment issues.

Im running a 280x600x80 intercooler and couldnt fit it in without cutting the crashbar or spacing it out.

There was a r32 at the skyline meet last Sunday with an intercooler 10"inches wide

But he was running 857 bhp

Looks like I got myself a near mint evo 6 intercooler, collecting it on Tuesday. To fit my FL what angle/size hoses will I need to order?

[GalantOnly]

Who need the crash bars anyway?? I just use them to keep doors open in the garage...

I never considered spacing the crash bar out by useing some washers, what a good idea, particularly if you only need a few mm extra to make things fit.
I will remember that one.

[jjayokocha]

Might do the washers myself cause don't wanna have the ic at a slight angle, so a 45 degree for the hot side and 90 degree hose for other do the job?

Why would you take a bigger intercooler and put it behind a crushbar?
Thats a waste of your capacity of the intercooler and waste of time to build boost, because it doesn't cool effective there.

I got a Autobahn88 600x200x70 fitted under the crushbar with the core fully in the wind.
Perfect fitment, good quality and very happy with it.

Because its a heatsink.. basically the i/cooler doesnt have to be in the airflow to cool the charge from the turbo's.

Remember the factory cooler is behind the crashbar too.

Thats illegal over here Alex, remember it also holds the chassis rails apart in a crash..

[NLduffyNL]

I wanted to keep my crashbar for my own safety. If a car hits me in the front it will be the crashbar first instead of some bits of weak metal and straight impact on the engine wich is pretty close to my feet and body.


Still, i bet the efforts of an intercooler (as big as possible) and got its core full potential in the wind, you'll get a better graph then a bigger intercooler wich has for example 100x600mm behind the crashbar. Thats just a waste of air because it doesn't get cooled effectivly. and because of that your air temperature would be hotter (No not a lot but still a bit) compared to the smaller one.
The reason you want a bigger intercooler is so you can cool more air.... behind a crashbar, it barely cools.

The crashbar only obstructs about 50mm at most of the intercooler. The bumper actually obstructs more airflow than the crashbar.

Example:


I've had a look and the bumper obstructs about another 5-7 cm at the bottom. Changing bumper designs (eg. the Crux kit) gives slightly more area for the intercooler.

[Davezj]

from a purely air flow point of view, i have modified my PFL front bumper to remove the jap number plate, cut the jap number plate backing away that protruds below the level of the rest of the bumper. remove original plastic mesh grill as this does not fill the gap now, make a mesh grill from metal mesh. Fit a standard UK spec number plate.
this makes a massive difference to the amount of air that can get to the intercooler and subsequently the coolant radiator.
i don't like the look of it but i need more air flow due to over heating issue when thrashing it. now the coolant temp does not go above 90 deg c when on a bit of a thrash.
so it does work.

i would have to agree with daniel above with regard to the bottom part of the bumper blocking a lot of the air flow to the bottom of the intercooler.

i must have at least doubled the amount of intercooler that is in direct air flow by doing my bumper mod.

[NLduffyNL]

I did a quick search on my comp, its not the best picture ive got, but as you can see, my bumper starts a little bit above the crashbar.
And i got my front bumper modified so it stops exactly at the bottom of the intercooler.

That sits in there very nicely, and looks great.

But as it is not a stock bumper plastics, it is like comparing chalk and cheese, (stock factory and aftermarket).

[NLduffyNL]

Thnx Your right about that.
But my opinion doesn't change that i would prefer a intercooler fitted between the lower part of the bumper and the crashbar instead of being there a bit behind.
But i think its a personally prefer. i dont have figures or something to know if its actually making differences.

One more picture of the people that might be interested, because the intercooler kit of autobahn88 is really great and fits below your crashbar.

It is an ideal size and eliminates the need for messing with the bumper bar. And will probably do a very good job. But not an easy size to find for little money, I looked for a long time to try and get a slightly smaller one but nothing ever came up for the money I was willing to pay. The 600x300x76 can be bought for about £85 new.

[jjayokocha]

I still have my square jap plate on but I've put it to the side to allow the fmic to get as much air as possible. Collecting the evo intercooler tomorrow so will throw up some pics of my £40 upgrade.

[jjayokocha]

Heres a pic of the evo fmic I picked up for £40, gna sit it in place tomorrow to try work out hoses and pipes. Do I need a pfl hot side pipe to get this onto my FL or can it be worked around?

[wintertidenz]

You can chop the FL hot side pipe and then put on joiners to fit it, but make sure that the pipe is clean inside after you cut it.

Alternatively just make up some piping for the hot side.

I've mounted a 34" modified IC on my VR2. It couldn't be any wider without chopping plastic off of the insides of the bumper!
