s5 turbo stock wastegate question - Page 2

FerociousP · 07-29-2008, 09:22 AM

seriously??

I plugged the wastegate and it boosted to 10 before I decided not to go any higher ... like I said in my original post.

Well it's only supposed to hit 7.5PSI stock, what did you expect to happen?

The confusion here lies in the simplicity of the answer.

FerociousP · 07-29-2008, 10:14 AM

with an open exhaust I expected it to boost creep a little higher than 7, with the ported wastegate I expected that to control that condition. I didn't expect 5-6 psi with a open exhaust.

I was looking for confirmation that it was in fact the wastegate actuator (spring and diaphram part) and would replacing it OR getting a boost controller be the best option, and then hopefully someone would offer a spare actuator or direct me to another option..

its all good, I have... a plan...

I have to replace one of the exhaust gaskets anyway because of a big leak so when I take it all apart i'll give it a good look over and i might have a spare actuator by then...

I say go with a boost controller.

TehMonkay · 07-29-2008, 12:00 PM

yeah me too

djmtsu · 07-29-2008, 12:32 PM

He has a boost controller, it isn't as effective as he thought however......or its broken.

Simple fix.

Remove all that stuff, install a large 62-1, tail 44 wastegate with 15lb spring. lol

Bust seriously - If the boost controller is hooked into the system, are you sure its plumbed correctly? Are any of the lines leaking?

lol, yeah, that would be a great solution!

well, how much are springs? Where can you buy them? Wouldn't it be smart to just replace it than risk it?

djmtsu · 07-29-2008, 02:09 PM

A 62-1 on a 6 port turbo? That would be fun for a little while at least.

85rx-7gsl-se · 07-29-2008, 02:24 PM

What kind of boost controller is Paul running?

djmtsu · 07-29-2008, 02:52 PM

I believe it is an old school HKS. I don't know what model for sure. It looks to be the same generation as his F-CON though.

FerociousP · 07-29-2008, 09:36 PM

the boost controller i bought is broke, doesn't work...

and phoenix, the stock spring is not replaceable

85rx-7gsl-se · 07-29-2008, 10:48 PM

Sad, I would have loved to have an old school HKS BC

Phoenix7 · 07-29-2008, 10:51 PM

lol. I never had to replace/fix my wastegate so thanks for the info.
