Reducing under engine temperatures

[warren_cox]

I've been getting some deformation of my intercooler pipe (front nearside), and wondered whether it was caused by heat under the engine bay or temp within the pipe itself + increased boost from remap.

Having looked at some of the threads on Samco hoses:

a) theyre not that cheap for 0.1% performace improvement
b) Some say silicon content is detrimental to cat and lambda probe

Would reducing the temp under the engine bay help at all? In the demon tweeks catalogue it says reducing the engine bay temp increases power using exhaust insulation wrap. Is this only an useful for cars without intercoolers?

Would it make any difference on an LCR or should I get on the phone to Forge Motorsport and get 2 samco pipes instead?

I know this isn't strictly 'Engine Tuning' but didnt know where else to put it.

i'd say do both

save power loss and reduce heat with some lagging

nd keep it in tow with the hoses

especially as Forge have a samco sale on @ the monet

Warren go samco m8,not heard of any probs plenty of peeps runnig this stuff mate,and custom ones etc

removing the undertray & under bonnet blanket helped mine no end (oil temps dropped a good 10C)

I think the main thing that's going to be causing the IC hoses hot enough to deform is the fact compresed air is being rammed through them...

OK, so cutting vents into your bonnet may help things, but I think upgrading the hoses is what's needed.

What's this about silicone damaging the cat?? New one to me!!

You could always keep your cat nice and safe in the garage!

undertray removal will lead to accelerated power steering belt failure, you heard it here first..
Due to water and dirt getting into and between the belts.

 

[warren_cox]

Settled, I shall do both!
cheers all

Max_Torque done once of his nice technical posts in which he pointed out that silicon hoses actually damage the cat/lambda probes (Can't remember which, probes I think).... I guess the post was in the Samco hoses thread.

Where's a "gulp" emoticon when you need one??

only over a long term use - say 50/60'000 miles

saying that most lambda's need cleaning out or replacing by then anyway

 

[CupraR-Rog]

And what's the cost of a new probe??

I'm starting to think getting the samco wasn't such a good idea now...

Well if you want to get rid of them Rog

I have never heard of a Silicone hose being blamed for lambda failure..... othe rthan lambda failure from normal mortality.. (lets face it how could you tell the difference)

Silicon spray however, a la shiney blinging up ya engine bay, can have a detrimantal effect.

Hoses are autoclave cured, and non volatile... but the aerosole sprays are more likely the silicon concern.

I wouldn't worry about the undertray either....
I lost my undertary when my car was a week old and the right angled lip it has caught over the top of a kerb when I parked.
Have done 60000 miles without it no problem..
I never thought about it but even in the summer and with revo my engine temp has never gone above 90degrees....maybe thats the missing undertray?
Engine bay is a little dusty though but nothing major and no rusty bits.

Gee... let me think...

Nah!!

 

[Jammy]

Be careful though, Engines are designed to run around the 90degree mark. Running at lower temps can be dodgy. Same reason you dont raz it when its cold.

I thinkt what they're aiming for is lower ambient temperatures under the bonnet rather than cooling their engine

but the point that people miss is that they're looking at the coolant, not the oil!

 

[LEO LION R]

I thought they were meaning reducing under bonnet temps, to help reduce air intake temps - ie lower induction temps by letting mor eair pass through the eangine bay ?

That doesnt make sense!!




The exhaust manifold wraps are a great idea, as not only do they keep heat away from the engine bay, but they keep the energy in the exhaust gasses which helps with turbo spool up, especially if the turbo is a long way from the manifold.

I am sure my tdi had hard pipes, inface my golf tdi has hard ic pipes as does my 944. Can you get them for the Leon?
