Delete. twin w2a ic plumbing

**danomite02** · 05-28-2013

Anyone have any suggestions on an effective plumbing of 2 w2a ic cores? Anyone with fluid dynamics experience, knowledge, advice would be greatly appreciated. The unfortunate thing is that the IC under the blower has 5/8 inlet/outlet, while the turbo IC has 3/4. Im a bit perplexed at the moment...

A simple adapter or stretching of the hose at two points wshuld fix your issue with sizing. Chose one of the two and stick with it throughout. On the duality.. two seperate front mounts or just one feeding both items?

For coming off the IC plate on the LIM, gates hose part # 20662. It's a 90* molded hose with 5/8" on one end and 3/4" on the other

I didnt mean the size difference in regards to making it fit LOL, i meant in terms of orifice size and flow restriction.

Both the supercharger ic and the w2a turbo ic will be cooled by one large 3.5in thick fmhe.

If you can't change the 5/8ths, you can't change it, I would just try to run 3/4ths whenever possible. The biggest issue is if one intercooler/pump fails. Are you using one pump with that large fmhe? Air to air ic for the turbo and w2a under the s/c would be the most effective on the street and simplest in terms of reliability but may not be optimal for the track. Do you have temp sensors for post turbo, pre intake or how many are you going to run?

When Matt had his twin turbo setup, he used 2 w2a cores fed by one large fmhe.

i have one large(biggest i could find) fmhe, which cools both a2w blower core and turbo core with one bosch pump

It would be best to run the same DIA. hoses.
The reason being, your 1 pump may end up pushing fluid through the path of least resistance. It may not flow evenly, or at all through one of the ICs.
You may have to run 2 pumps to ensure flow.

Just a guess and something to think about. I'm not entirely sure exactly how it would work.
