Metal Plumbing

[ugy]

The other day at the drags I seen a turbo with new plumbing. When I touched it the

pipe from the intercooler to the throttle body was almost to hot to touch and he had the bonnet up for about 10mins. When I touched my rubber hose it was cold. Surely this must be detrimental to performance. I was thinking of getting mine done now I am not so sure. Any thoughts on this.

Thanks

Makes ya wonder doesin't it

If the pipe is hot because the gasses inside are hot - then the fact that the pipe is hot is good - as it is helping to expel the heat.

but... if it is hot from the engine bay heat warming the pipe - yes bad.

I would have thought the alloy piping would be better at expelling heat, and not soaking engine bay heat?

Also - the piping can be lagged to insulate the pipe form engine bay heat (use same sort of stuff as used on headers etc, a fibreglass wrap.

With the engine off, the pipe will get hot however, once the engine is running, the airflow through the pipe will carry away the heat. The actual heat transfer from the engine bay to the metal pipe when in operation is going to be minimal and damn unlikely to affect performance.

Yes that would be correct. I think the only way to tell would be to touch the pipe straight after the engine was turned off to see if there was a problem.We turned our cars off at the same time and like I say his was very hot and mine was cool.

I would be interested to find out how the new plumbing works regarding extra power as I am looking at this to be my next mod. Maybe somebody who has had it done can help.

Thanks

you touched your rubber hose and it was cold, lol.

it doese seem a little strange that his piping was hot directly after you turned the car off, but what kind of driving had you been doing?

Also even if the pipe was to hot to touch I wouldn't be extremely worried, next time your out put you hand on the exit side of your intercoolers, this will give you a better indication of how your systems are performing, heat wise anyway.
