Hi!

Is there a noticeable difference by fitting the bigger hks intercooler and aluminium piping kit?

Anyone has it fitted?

Hello Maxi
I have tested a HKS Intercooler and piping kit and found it to be only 2dc better than the standard intercooler so it was a waste of money.
Thanks Mark

Mark,

This was good to know - esp. when the HKS intercooler and amp; piping is over a grand. Just for info, you say a '2dc' improvement - do you mean 2%, 2 bhp or something else?

Hello Steve
It is 2degrees celcius air temp when the stock intercooler was 24c and hks was 22c you can see it is not a worth while differance,I like to test parts before I will sell them so you get parts that are reliable and work which is the differance between myself and the so called other tuners.
Thanks Mark

Yes that's good to know, but I mean the standard intercooler looks pretty OK to me, anyway there's not much to cool down, the standard Evo is not that fast I think.

The standard intercooler looks pretty ok to me!!!

Claudius,every single standard part looks ok for you!!!
The standard brakes,the standard turbo,the standard filter,etc,etc.ok.
BUT EVEN THE STANDARD EXHAUSThttp://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >!!!!!!!!!

The standard parts are there just to be changed!

Saying that they are so expensive to change is a real thing,but no they're not ok[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >!!!

So how's your AYC equipped TOMMI MAKINEN EDITION with the stage 4 conversion(BLITZ FILTER,DUMP VALVE,RALLIART KEYHOLDER AND FLOOR MATS)?

Are you still giving an evo vi for free with the alpine hi fi system you are trying to sell[img]http://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >?

But even if all the standard parts are ok for you then you keep complaining that the evo it's not fast!

So why don't you prepare it?
Sell your evo vi at the real price(1800£)and buy the parts for the tommi!!!

The standard intercooler is pretty efficient as it is and I didn't notice a difference with my HKS intercooler at first, but now that it gets warmer the difference is quite big and I'm sure it will make a difference in Monaco. Madevelopments, what how warm/cold was it when you tested it? Also, it is quite a bargain if you consider custom made intercoolers as I got mine for 500 quid as handluggage from Japan.

A thought here - the temperature difference is one thing but the overall airflow efficiency could also be improved by better piping. I noticed that the standard piping on the turbo side has a pinch point where it is slightly flattened (where it is closest to the ground). Could the HKS kit imrove overall airflow? If you have got uprated induction and exhaust it is possible the intercooler piping become the restricting factor in the engine's breathing.

Any thoughts?

Steve.

This is true and as I wrote in another thread it ####ed my cars boost level up. My ECU had to be remapped after I fitted the piping because it went through the roof. Another thing was that my car started stalling, buy this was sorted out with a HKS Idle Stabilizer.

So Mickael K you are saying that one should FIRST fit all the pipes and intercooler etc and THEN get the Motec?

Madevelopments, How did you measure the air temp? While driving?
 
G

·
Discussion Starter · #12 ·
As I have learned now one should first get the Motec (screw all other upgrades) and then all the rest... You still have to remap, even if you have the Motec. Before you start with the engine I'd recommend to get a Proflex (or Öhlins if your Mr. Money). All of this has sadly been learned through hard and expensive experience

Michael,

I do agree with an ECU being a good starting place but think that there are many computer alternatives. Understandably you favor Motec as you are familiar with the product but there are other companies that produce excellent hardware. I have fitted a GEMS and have never regretted the purchase. I have also heard good things about Haltech and Link seems a good budget alternative. I think an ECU upgrade has more to do with the implementation than actual hardware.

Upgraded intercoolers are only required when boost is increased or a larger turbo is installed (same thing in a way) , then the intercooler wud need to be at least 30 % larger to provide a benefit , this means custom made and body mods to install.

Don't expect too much from most of the bolt on aftermarket products , they are marketed to exploit most petrol heads urge to upgrade their car easily. Serious extra power costs money and needs knowledge , unavoidable I'm afraid.

Hello
Test was carried out 5c outside temp so you can see they are 19c and 17c above ambiant temp so the diferrance shows the hks intercooler upgrade is not actually worth while,and to say its better now the weathers warmed up without refitting the standard intercooler you are just fooling yousel if you are fitting a bigger more efficient turbo running the same boost you are actually suppling the intercooler with cooler air so it is more efficient,you actaully need to test each part separately so not to fool yourself in to thinking the parts actually work.tests where carried out with a K type probe and a james scientific display which has a super fast update rate test was carried out on the road from 30mph to 130mph through the gears so to make the intercooler work hard,the hks core is the same but slightly longer.
Thanks Mark

standard pipework is restrictive in places ,restrictions cause pressure and heat,the hks kit is very well flowed/fits well
hks cooler needs chunks taking out bumper,moving watersprays,and is a bit of a fiddle
size of std intercooler is ok,its the core you need to change for any benefit.....
more efficient trick internals
if you are going to mod your car,you need a combination of parts
an ecu alone is useless

Surface area and depth of core determine the rate at which the intercooler (incorrect terminology btw , the correct term is aftercooler) can dissipate the heat. Internal flowing effects the pressure loss within the cooler hence loss of boost pressure.

Look at any turbo race car to assimilate what is needed when serious power is the issue.

So Michael

you are saying that you should get a Motec mapped, then install HKS piping, then get it mapped again, then install an exhaust, then get it mapped again, then get an air filter, then get it mapped again???

Why wouldnt you just install the following
exhaust with extension kit
alu piping and silicone hoses
air filter
and then Motec M 48 mapped to your turbo pressure specification
 
G

Discussion Starter · #19 ·
No, no, no! I'd recommend getting the exhaust and filter done at the same time as the ECU, otherwise there's not much point. Then when you get bored of that start adding more bits. I've had my piece of **** ECU mapped twice by those brainless monkey's at my least favourite tuning garage...

I got the HKS intercooler and I dont know if it was worth to install...I do have a bigger turbo these days(HKS gt 28/35) but I cant tell if the original intercooler would have been good enough as it is running on a calibra these days...
