Would fitting a intercooler give much more gains in power without the remap or would this have to be done to see any real gains.

Won't give you any real gain in power.
But it will stop you from losing power when it gets a bit hot

Yes it would

The larger the intercooler, the greater the cooling effect, the cooler the mixture, the greater the power potential.


I don't know enough about the Noble ECU to say if you would need a remap (isn't there a laptop program you can tweak?)
But you will be getting cooler air so you could now add more fuel = more power.

Does the Noble has an air mass sensor?
I guessing the ECU should sort it out if it has.

As mrpbailey say's just changing the IC won't give you more power but will help the loss of power when warmer, however with a remap yes you should be able to gain abit although would be best if done I conjunction with other upgrades.

What do you guys mean by when it gets hot?

So my understanding is the hot exhaust gas spins the turbo, the intercooler cools that air, surely a better bigger intercooler will give air more dense and has more molecules into the engine.
So when you say hot do you mean when the tubro is spinning for example at the top of the rev. range?

Or do you mean for example after you have been driving the car hard for 5 mins?

When you squash something, it gets hot.
When you squash air, it gets hot.
A turbo squashes air.
Turbos make air hot.

When the weather gets warmer the standard intercooler doesn't get a lot of air therefore inlet temps rise & reduce power, by fitting a better intercooler & improving airflow in & out of it helps maintain the power thumbup

[quote=CaptainPeter]What do you guys mean by when it gets hot?



The Nobles engine compartment has next to no air flow running through it, the turbos along with the inlet manifolds and exhaust, creat huge amounts of heat in that area, the IC cant handle the temps, and so the car suffers heat soak, so looses power. This is mainly a problem on track, or very long journeys. Adding a more efficiant IC will help with that problem,
but will not solve it,
The tunnel mod that we do also helps allow more air into that area.
Then by mapping you could see a small gain in power, but more importantly tbe engine would be more efficiant.
Hope that makes sence

Every day is a school day, but I'm still a bit confused.

So if you had a standard car with a standard intercooler and a standard car with an upgraded intercooler, they would both have the same power, same speed, but one would get hotter quicker.

Driven hard what are we talking 3mins' 20 mins'
Most people running 500+HP don't have a standard one, I was thinking colder air more fuel more power, but it looks like I stand corrected.

Basically a standard car wont make more or less power with a decent aftermarket intercooler... the standard intercooler isn't restrictive at stock power AND it works ok at cooling stock power on the road.

However power will be restricted when your on track as the stock intercooler isnt great at cooling for long periods and once the inlet air temps reads over a certain threshold the ECU pulls boost out the car and power drops like a stone to protect the engine.
Hence people are saying upgrading the intercooler stops you loosing power but doesnt give you more power.

If you modify the car then the stock intercooler becomes a restriction as it cant flow enough air efficiently and thus it will be loosing you power and you need to upgrade.

What power bhp can a standard intercooler take.

Having said that, my standardish car was noticeably more responsive once the ProAlloy was fitted - even on a cold day...

Well... it might make more power.

If the new intercooler is very efficient and has less pressure drop across the core then it would stand to reason that you might end up with a bit more power.

No need to feel like you've been corrected! What you're saying is true of an upgraded car where dense air makes a difference to the power. What Andy is saying is that with standard power the intercooler is sufficient in most cases for the ECU to manage and when the cooler is overwhelmed, the ECU reduces boost to attempt to cool the charge air. Therefore replacing with an uprated intercooler alone isn't going to allow the ECU to trim anything beyond its mapped tolerances and so you'll see very slight improvements at best due to the adaptive maps taking advantage. The bigger change will be the ECU is far less likely to have to rein in the boost as the charge air won't have got to the programmed limit.
Remapping a car after an uprated part goes on allows the mapper to effectively move those tolerances around and tell the ECU what new limits it should work within.

One thing to note in the middle of summer on a warm sunny day after being stuck in traffic the std intercooler will not get the temp down to ambient !!!! No matter how far you drive , a bigger intercooler will achieve that much easier !!
