The Intercooler Thread

[Peter_D]

OK so if I'm understanding this thread correctly our best choice would be.
Intercooler PIPES 2 to 2.5 inch stepping up to 3 inch at the intercooler inlet and of course returning to 2 or 2.5 at the outlet.

The Intercooler size anything around 600x200x70 including Benny's 400x300. But nothing bigger than 300 as it is to high and nothing wider than 75 as some metal cutting will need to be preformed. Bar and plate is best.

Check the inside of the intercooler to insure that it is clean of metal fragments which could "frak" the motor.

yeah but is that relevant to me, remember only 12" from turbo to intercooler and 4" from intercooler to throttle body..

Yes, forgot about your application-sorry
In that case, get an expander from the turbo and keep it 3 inch, get a cooler with 3inch inlet/outlets, 3inch to throttle body.

Should be very responsive

Intercooler PIPES 2 to 2.25 inch stepping up to 3 inch at the intercooler inlet and of course returning to 2 or 2.25 at the outlet.

Peter, Yes, i would suggest a PWR core in the 400x300x100 size- they are the best value for money in that size.

The A.R.E cores are industry leading, you will pay more for them as they are without peer. Richard has spent 10 of thousands of hours testing and developing them for a massive range of applications.
I use and custom dual pass core as my radiator in the nissan, its smaller than the oem core and incredibly efficient. never gets above 79degrees on road and never above 90 on the track. I challenge any other company to better that

The throttle body is 60mm (sometimes 64mm) which is around 2.5". To me it makes no sense in reducing the piping out of the intercooler to 2" or 2.25", you might as well make it 2.5" the whole way to the throttle body.

 

[Outlanded]

Just to add;
I have factory y pipe then goes to 2.5 from the join down to the fmic (600x300x76) then is flared upto 3" into the cooler then 3" out of cooler flared down to 2.5" all the way upto throttle body with a silicon elbow that goes from 2.5" to 2.75" for the throttle body. I find this to be very responsive and boost comes on faster than stock application.

 

[timmae2006]

anyone out there heard of a delta fin IC. Looks interesting

does anybody know much about this style of cooler??

 

[naughtika]

dunno much about it.. but i know X3E can supply as well..

 

[timmae2006]

will a 600x280x76 fit without any compromise anyone?

 

[bradc]

You will need to modify the impact bar a bit.

fellas.. got a question lingering in my head for quite some time now..

as we all know most intercooler install are on a vertical position.. are there benefits in positioning the intercooler in a slant position? as in the top being leaned forward or back a little.. I notice this kind of install are done on RX-7 (Series 7 or 8?!), silvia (s14 & s15) and i think i saw a couple within supra..

what's your comment about this type install?

 

[Outlanded]

I think they do that because of space restrictions in rx7's as they are very small nose... to get the bigger cooler need to tilt it? thats my guees anyway

 

[SiliconAngel]

Chris in order to achieve maximum airflow through the core you want the IC mounted perpendicular to the flow, ie vertical. As Brent said, angled design decisions are made to overcome space restrictions - as we don't have to concern ourselves with that in the VR4 (in fact, by angling your IC you'll have LESS space) its not something I'd concern myself with

 

[naughtika]

i knew that our coolers won't have much room to play with, its just a thought i've had..

what if we had the cooler on an angle (top part leaning forward) and have vents to guide it out to the back and/or out the hood? and as well as have air guides at the fronts too.. ?!?!

 

[BuzzPuppy]

A 600x260x76 with the end tanks fit fine on mine (again sourced from Ivan).

It seems like it won't fit together (ie, cut/bash the crash bar) until you bolt it in and works like a charm. No movement at all and sits vertically

 

[Guest]

christian, that will work . An intercooler can be mounted at stupid angles and still retain almost all its efficiency, i'm talking 45% plus. Have an article on it where it was done

 

[godzilla]

just popped into Autobarn and they are selling 600x300x75 bar and plate coolers for $229 ! has anyone else seen these, or for that matter bought one? was under my car on the weekend and found that my cooler has taken a bit of a hit underneath it and i am thinking for that price i should grab one just in case mine has a bit of a leak.

 

[Outlanded]

you can get them cheaper on ebay

 

[Guest]

hey guys is there any good places in sydney that do custom intercooler piping? i have some coolers im looking at just waant the hard piping done adn install bov.

cheers

 

[sexspecvr4]

wat do u guys think of his as a cheap option?????? should work with a

little bit of work

 

[bradc]

You might be able to cut it to pieces to get it to suit but it will be a lot of work.
