has anyone expereicned any pressure drop wen they installed an aftermarket intercooler or anythin... my boost sits at exactly 20 if not 19 now and before it used to be at 22-23 stock turbo with mods of tbe and hks filter

 

more volume to fill with the larger intercooler, its normal

 

yup normal...the IC design that I've seen have the least pressure drop is the Delta fin design Apex style.

 

you will get a drop because you need more air to fill the added room or the new intercooler. i dopnt have a Turbo XS but i didn't get any loss in pressure drom, but the Turbo XS one is bugger then mine

 

According to Buschur, a free flowing I/C shouldn't have any drop in boost. In fact you would have to dial the MBC back a bit.

Besides, once that extra space is filled, how does boost still stay lower than previously set? The extra space might induce a bit more lag as the space fills up with air, but pressure/boost shouldn't drop unless it's more restrictive.

 

i didnt experience a pressure reduction after installing my tuebo xs fmic?

here is my thread: https://www.evolutionm.net/forums/sh...d.php?t=227201

did you do a boost leak check?

 

Because the turbo still has to push more air than with the stock intercooler, therefor you need to turn up the boost controller to make the turbo work harder to keep up with the demand of pushing more constant volume.

 

I don't see how the turbo has to push more air. Once the internal volume of the I/C is filled, the amount of air coming into the inlet is equal to the amount coming out of the outlet.

When I added the AMS I/C to my old E8, the boost didn't drop.

 

i installed mine on saturday, no boost drop whatsoever. It spools a little bit slower but nothing tragic...

for the money its the best unit by far!!!

 

I had absolutly no pressure drop when I installed the same intercooler. Check for a boost leak man...

 

yeah i guess im gonna have to do the boost leak test and i also gotta connect me ebc to as well but i'm pretty sure those clamps are on tight and good even though the clamps suck and i gotta get some better ones
