Not Holding Boost In R32

[johnny84]

hey, got an R32 gtst and running 10 psi. when im nearing top end on 2nd and 3rd i lose 2 or 3 at most psi. also query on turbo is in r32

[sproosy]

i guess your referring to top end as around 6 - 7000 rpm?

[johnny84]

yeah from like 5 to 7

isnt that per normal for any turbo to start to drop a bit of boost on the high end? i know mine does and the guy at uas said it was normal and good

[boj01]

What type of boost controller are you using?? If its a manual bleed valve then that would be why its dropping off.

That's pretty normal for an r32 stock turbo, especially without a boostcontroller (just using the stock actuator alone). If you have a look in the forced induction section, people have posted responses on how to solve this problem.

Personally, i'm using the jaycar iebc. It has allowed me to sustain 10-11psi all the way to the redline, and build boost much quicker too.

manwhor3,

i tried search in forced induction section for responses on how to solve the problem, but no luck

Mine doesnt drop off... then again it doesnt reall come on till 5,000 (HKS 2535)

Its just because its the standard turbo. Nothing to worry about i have driven many a standard R32 and theyr all the same.

A full exhast system with dump and hi flow cat give a bit more in the top end.

my 32 done the same. i had cat back exhaust at first. i finished it off with a turbo back system and defo felt more gains, esp midrange to top end. still same boost though.

then put a fmic on. at first it *still* dropped the boost. but now, for whatever reason, it holds a steady 12psi...

no controller or anything.

i think its just normal. many posts on here saying that drop boost (even me! )

Mine does it too, I was worried about it aswell.. i'm running at 12psi stock turbo..have a FMIC and pod.. and catback exhaust It just feels like its restricted or something.. if its normal then thats ok... I was stressing i was f**king the turbo. somehow..
