Couple of Q's for the Exige tuners

Couple of hopefully very quick questions you guys may know the answer to.

If an Exige S has 240 bhp at the hubs/wheels, what is it likely to have at the flywheel? I know this will be a estimate but is there a rule of thumb for a Toyota powered Exige?

Secondly, what sort of surface temperatures can you expect on a ali Forge intercooler when pushing hard on track? (I.E how hot will the actual top surface of the intercooler get)


Sorry if these questions are a bit basic - I’m new to Exiges (but loving every minute of it so far!)

About 10% loss is about what I go for, as for temperature no idea…

Not sure if you are talking about a standard 240 but that is the power produced by the engine not the power at the rear wheels.

It’s not a standard 240, it’s an Essex Autosport tuned Gotham with a forge intercooler and Larini exhaust. 240 is at the hubs (EA’s dyno)

Frying eggs maybe??

We used to do this on the exhaust of Centurian tanks when on exercise!!!

Not fried eggs :slight_smile:

I’d like to tone down the shiny silver intercooler as it’s looks a bit too “bling”.
A mate runs a sign writing company and suggested making up a rectangle of dark vinyl to stick on the top surface of the intercooler.
Purely cosmetic and loads cheaper than anodising it black.

Don’t bother, shiney makes it obvious it’s not the OEM rubbish ( or not depending on where you read) and black absorbs heat not radiates it (small potatoes but I like to show i remember physics O level at all opportunities)

Yeah don’t knock the OEM cooler too much. :wink:

Too right ,they’re ace …
Anyone wanna buy mine ?
:wink:

Vinyl will melt in this situation, as would egg!!

That sorts that out then - vinyl is a non starter!

The only times I’ve actually felt the intercooler after driving, it’s just been luke warm.

Sounds like I need to try harder :smiley:

It looks miles better in chrome IMHO and as pointed out above black is the worst colour for an IC as it will soke up more heat from the engine bay :slight_smile:

As not exactly demonstrated in the I/C comparison thread last year where OEM did rather well against the forgery and others :wink:

OEM cooler in black available from me now…
Roll up roll up !
I’ll let it go for half the price of a forge …
BARGAIN
:smiley:

Its simple physics, black absorbs more heat than a lighter colour. It might not make much difference on the move but it will when stationary.
My Forge has the gold stuff on the bottom.

On the subject of surface colour…
black colour = high emissivity/absorptivity"
In other words black absorbs radiated heat well but also radiates excess heat well.
It’s no accident that most of the Worlds automotive/commercial radiators are black !
I see no reason why you shouldn’t have it sprayed Matt black if you wish…After all The original is !

Mine’s not… :smiley:

The amount of heat lost by a car radiator by radiation is less than 1% of the heat it loses by forced convection. The reason they are painted black is because it’s the cheapest paint. Think of the Model T Ford. :slight_smile:
