Anyone bypassed the water pipes going into/out of the throttle body? Can't see the point of having heat going on in there....is it as simple as it looks to do? I'm making the assumption that the two small pipes, one either side of the bottom of the t/b are the offending items...if so, is it a case of just removing them and joining them together? Basically, just trying to lower inlet temps.

 

Yes, yes, yes and yes.

But you may need to reconnect in winter to aid warm up in cold weather and prevent 'carb icing'.

I dont think your going to gain much performance or benifits...

Think about it, your turbo will be pushing air into your engine at, at least 0.9bar so its not going to have enough time to be heated up by the throttle body..

Thanks lads, somewhat conflicting views there, but both appreciated nevertheless!

 

But it costs nothing and may help to reduce inlet temps...

My thoughts exactly, cheers Floyd. Incidentally, have you actually experienced the " icing " problem....I live in the sunny south and as a consequence, have forgotten what ice is!

 

Carb icing is not a problem with fuel injection, the injectors operate at too high a pressure for any "ice" to block them up

Matt

 

Yes but the throttle can ice/stick i think

Only reason i gave my answer is because its been discussed before and the hassle of reconnecting it for winter outweighted the performance increase.

The temps in winter here shouldn't cause the throttle to ice up. The sytem is really intended for places that do get really really cold, further north then the UK. In terms of heating the air... yes it does. The intake charge will ideally be about 40degC, the throttle body and inlet manifold will be heated by the 90degC coolant so it will make a difference. Every little bit helps. Have you felt how hot the inlet manifold gets.... if you disconnect the coolant to the throttle body and ISCV and use inlet manifold spacers you will be surprised how much difference it makes

Tone, any recommendations as to a supplier for manifold spacers? Thought about this before, didn't pursue it due to being overcome by laziness!
Btw, any comparisons re. temps pre/post spacer and throttle bypass?
