Another quicker mod for your setup...

Bottleneck at your upper intercooler pipe to the intake mani. Replacing with a 57mm 45 degree pipe (and some choice silicone joints) removes it.

Past this point, the only other mod you could do that would improve things would be intake mani swap for a PD130... And a TIP swap...

It's a shame I couldn't get an old school old-man intake but that'd have to come from the US, or get someone who is good at fabrication to make me one...

...Any ideas?

cool 57 mm great 2x 45 deg and some straight bits. I did wonder about the choke of a plastic hard pipe.

air box cold feed and snow trap removal to do

whats old-man intake?

The old-man intake is what someone designed individually as a replacement for our TIP.

Designed to improve turbo spool up and reduce smoke.

A lot of the pipework is extremely restrictive on the ALH and lots of people have seen noticeable improvements at each point removing the bottlenecks.

If you think about it, with more fuelling you need more air. And more air that is cooler. So if you can remove the bottlenecks and can keep the air cool then you improve your power

I understand the concept and have seen improvements after changing pancake, but i cant see how that kit pictured will fit, but it has given me ideas and ill probably mock something up with silicone bends and straight sections of alli

cheers mate one more bottle neck to go

Well that kit there according to kermatdi fits ALH's perfectly - so... *shrug*

If you do manage to knock something together, if you could save me some details I might be interested myself

ill have a go, the way i see it from IC i need a 45 deg bend (hard) then a straight silicone, followed by straight piece maybe 10 inch (hard) and another silicone 45 deg bend - straight hard piece then to existing pipework to inlet manifold

Im on it, ive found someone local selling a cheap induction kit, dont know what car ots for but i can use most the bits and sell the filter end.

Ahhh you're still talking about the upper intercooler pipe...

I was on about the old man intake - that goes from your airbox to your turbo intake.

this is all very good cause lofty is my lab rat so to speak so i can learn from him whats good to do on the car and whats not since both our cars are the same engine and box ect......

Hehe - whereas i'm also an ALH'er so whereas my knowledge of them is quite extensive, funds and time to do stuff has been low on the ground...

...So it's good to see someone taking my recommendations and putting them into practice.

I think for me, my tinkering will come _after_ christmas now but then it'll be extensive lol

well shed some alh mod info my way aswell

ah for the turbo, ill prob not bother with that side too much, but from the ic to inlet man is a tiny little restrictive pipe

And what would you have in mind?

Common mods on the stock turbo are replacing all of the pipework with better options, vent arch mod, PD130 intake manifold and an EGR delete pipe... Removal of the snow shield and some ducting to the bumper for some fresh air... decat and straight through exhaust... Injector nozzle swap...

If you want more extensive then it's replace the turbo and go for a remap using your new nozzles... Which will probably result in needing a replacement clutch anyway and whilst it's off a single mass flywheel...

And to support the turbo then it's FMIC really.

You can go much much further such as PD pistons, cam, 5th gear swap (which is better for economy as well as opening up your top speed when you have more power), etc etc etc.

Just depends on how far you want to go

oh and all these bits im doing dont cost nothing, gutting cat free, pancake 5 quid. pipes and bits building up for free. I love it, it works well, may not look amazing but will do same job

get me some "cheap" parts
