FMIC - Single Or Twin Pass?

[Phoenix27]

Pro's and con's of each please guys?

I've had a little search but all i'm getting is 'will this intercooler fit?' lol...

Looking into this later on in the year maybe, i'd prefer a twin pass as it looks neater and a bit easier to install, but a single pass seems to be the way forward for everyone else (the cheaper way too, although i'm happy to pay a bit extra).

i had a twin pass on mine which was a bit on the large side but the piping finish was hidden. on a single pass you will have a shiny pipe going to the back of the bay. power wise etc you will have a few different opinions but andy lang on (used to be on) here managed to get another 40bhp from my old one (dont ask me how).

What bends did you use as i saw your dual pass set up and it looked wicked. Much better than other uni fit fmic's. Thanks mate. Daz

 

[SalSheikh]

i used some bends that were made up by a custom exhausts place but i wasnt too happy as it had some 90 degree bends so the flow was a bit pants. it should have been much better tbh and could have been but the fmic was too large. there is a smaller one available on ebay which would give a bit more room to play with.

twin pass for me. you have seen mine anyway. mines mahosive too.!

 

[cupra-db]

so are you happy with the results G1NG3R? been looking at your built thread, youve been very busy lol, thanks

 

[G1NG3R]

yeah well happy still not mapped yet and run 197.8 on the rollers. yeah been a bit busy with her if you look at my facebook theres is loads more pictures on there too if your intrested.?
search me its 'Lee On-cupra Jones'

Depends what your plans are? If your looking to go the bigger turbo route then go with a single pass straight away as the flow doesn't get cooled twice like a dual pass intercooler but flows much quicker, that's why I had to change from my forge dual pass to the cupra big race single pass intercooler.

 

[Mo Arif]

which ones single pass the one I have? or do I have a dual pass (pipes either side)

 

[ADAM_84]

Pipes both the same side is a twin pass as it goes in gets cooled, then back again cooled again and then to the intake manifold.

Pipes either side is single pass air goes in gets cooled then off to the intake manifold, single pass has the quicker flow rate.

 

[Mo Arif]

i'd stick with singe side, why else would top performance cars use them

Not planning to go big turbo for a long time, just a nice high stage 2 will do me. The performance differences between a twin and single pass are negligible at the level i'm going to apparently.

The twin is looking like a good direction to go.

so effectively your saying single pass is better? The forge one is dual pass at £700, toyo is £250 and single pass.

Which is better single or dual? Best performance?

 

[ADAM_84]

Cooling wise the dual pass will cool more because the air is going round twice where as single pass is only going through once but flows quicker which is why they are used for bigger turbo applications.

With regards to Forge there dual pass LC intercooler is more expensive then most but it is a superb bit of kit fits spot on, I know because I had one, without companies like Forge you wouldn't get the cheaper copies. The Forge LC intercooler is made to fit straight on using new silicone pipes to the intake manifold and to the pancake pipe where as the toyo sport goes over the top of the engine and to the intake manifold with various opinions on fitment.

ah right. cheers for explaing that. i want FMIC in the near future but really dont know what to go for. £700 forge/ pro alloy or the likes of toyo kit which loads have tried and tested for £250
