Blipping the throttle to around 4k in neutral with the bonnet open you can clearly see the pipe (post ic above the turbo running to the throttle body) implodes...

I've seen silicon pipework collapse pre turbo due to fiter/inlet restrictions but never seen it post intercooler.. I thought the APS ic was fairly free flowing?

I've checked for restrictions/blockages but found nothing. Has anyone else experienced this with the APS?

I wouldn't worry, it's only ever going to be a problem at high vacuum. As soon as the post turbo pressure is around atmospheric, there won't be any collapsing.

Pipes collapsing before the turbo it's still a problem, as high boost will generally mean higher vacuum before the turbo than low boost.

Harvey has had some stainless stuff done for his.

IMHO aps pipe work is ****.

Perhaps David but a fair few people have had good results using the APS FMIC though....

Just a thought

What's people's opinions on heat soak when using metallic pipework?

Matt

Pavlo

not really a big problem, but insulating around hot components like turbo a good idea.

heatsoak is a much abused term I think

Guys,

Dont see why you are upset about this excellent feature! The APS pipework has obviously been designed with a variable intake path geometry system such that the intake tract tubes offer variable internal diameters depending on the engines needs... on vaccum, they shrink to improve gas speeds through the lower bore of the tube, and on boost they billow out to improve flow capacity through them! How can you dislike suck a clever system?

matt,
sorry but that is the lamest argument I have heard in ages.

Just because people useit with success does not mean that the design might be flawed or capable of being improved upon.

Plus it is entirely subjective.

Before my car blew up it was running like a dog with a dodgy standard fuel pump not up to the job in hand. A nova boy would have gone for a ride and thought it was greased lightning, because his perception would be different.

Since most people only tend to fit one fmic in their tuning lives, few are going to know the difference between decent improvement and dramatic improvement.

Personally I think the aps pipework is a nice idea, it just doesnt suit my boost needs.

mutant_matt

LOL @ Moray - Adam **** off

I was just pointing out that people have had successes with it, that's all. I said nothing about it being the best , either in application or design

Haven't there been people who have indeed gone from one FMIC to another (e.g. Pace to something else? )

[devils advocate mode] Interesting that the new APS front mount for new age has I believe got steel pipework [/devils advocate mode]

Don't get me wrong, I'm an APS fan, I have an APS exhaust and love it. But if they didn't think there was a slight possible problem, why did their "continuing product development" change this?

Matt don't listern to Adam he's just feeling old and washed up

i am old.

am almost 30 now.

Matt,

I know I have changed intercoolers that was why I said what I said

ps. **** off!

I know you never said it was the best, but as I said, great results are subjective. You are just being defensive cos you fancy APS intercoolers and dont want to publicly admit your fetish for heat exchanger cores.

mutant_matt

Adam,

You are mistaken - I don't fancy APS Intercoolers, I fancy going for a drive in my Impreza.

Shame you can't do the same

Matt

MorayMackenzie

Matt,

I suppose its good that _someone_ fancies going for a drive in _your_ impreza.

tee hee. lol @ moray.


Matt. why would I want to go out in your car? its a fugly. people point and laugh!

scoobeee

maybeee its R E L I A B L E guys but then you wouldnt know what that means would you

ho ho ho
