s5 turbo stock wastegate question
 
heres the deal:

s5 n/a block with complete stock turbo setup.
boosts 5-6psi max
If I plug the wastegate line it will hit 10 (before I backed off)

would that be a weak wastegate spring??

If so, I was thinking about a boost controller or just replacing the wastegate... my plan was always for 9-10 max. what would be the best way go?

anyone have a spare wastegate actuator?

port the wastegate.

Monkey, how would porting help? Its already ported which we think is the problem...The stock spring is like 7-8psi, but a 7-8psi spring starts opening earlier to maintain 7-8psi....With a ported wastegate, it takes less actuation to achieve the same wastegate venting so by the time you reach 5-6psi, its already opened as far as a stock gate at 7-8psi.

ahh, read that completely wrong.

Yeah just try another actuator, unfortunately i dont have any of those though.

No problem man, you just had me really confused lol :rofl:

thers some way you can rig a spring on the out side of the wast gate to make it open sooner IDK a guy on a nother forum had one set up for some sort of bild he was doin but if i was you id just git a new wastgate make ur life a hole lot easer

why not just use a boost contoller, manual or electric

I was wondering the same thing. :dunno: I figure the wastegate was faulty since he didn't metion anything about a boost controller.

FerociousP 07-28-2008 09:18 PM

I did mention something about a boost controller... about possibly using one if that was the best alternative...

I'm not using a boost controller and the wastegate is ported.

85rx-7gsl-se 07-28-2008 09:29 PM

There ya go Paul...Making things all confusing like :D

FerociousP 07-28-2008 09:41 PM

no i'm not... people don't pay attention :)

TehMonkay 07-28-2008 09:50 PM

as long as you didnt go too big on the porting, or perhaps you need to adjust the actuator? I think there is an adjusting nut, dont blame me if i'm wrong though.

FerociousP 07-28-2008 10:03 PM

i don't think its a porting problem because when I didn't hook up the wastegate it boosted past 5 easily

85rx-7gsl-se 07-28-2008 10:17 PM

I think you will have this problem with any stock actuator, bigger wastegate porting will cause this regardless IMHO. Get a boost controller :icon_tup:

TehMonkay 07-29-2008 08:29 AM

if he plugs the wastegate line, it should go past 10 no problem, theres something else wrong that a boost controller cant fix.
