Hi All,

When all of You have put on a frontmount IC,did You gain or loose boostpressure???

I have just installed a costum frontmount and i have lost 0,1bar in boostpressure.....

Is this normal or is the IC crap.

The piping from the turbo to IC is 2" and from the ic to the TB is 2,5".

All info would be great.

Depends where your measuring boost from - remember that boost is simply the difference between atmospheric & where the gauge is, and the actual measurement of boost is how much air is not getting into the engine .
A good IC should have minimal pressure drop across it, i.e. a 1psi drop across it rather than a 3psi drop.
It seems more likely to me that the boost is lower as there is more flow & the turbo has more trouble keeping the pressure high at the inlet manifold as there is less pressure drop for it to go through to get there - so there's actually more flow. Also taking into account that the charge should be denser, so the same pressure differential would mean greater airflow (hence a small drop in differential is likely to still mean a greater airflow - although tricky to tell without numbers ).
Of course, I may well be talking [can't remember what words we are allowed to say on here now but insert one of your choice; I suggest 'bollocks'], but it's one explanation

Thanks,

I hope it will not be a problem when i this weekend install my 555cc tomei injectors and the TD05.....

Hope the gearbox will last

Do You guys think that a 2" pipe from the turbocompressor to the IC is to small???????
