I'm going to try a billet alluminum one and be able to change the spring in it like this one:

I'm really interested in the results you get with the forged bypass valve, I have been waiting on my GTM S/C kit for quite a while and I already bought a forged bypass valve. To tell you the truth that fluttering sound will drive me insane, it makes me have second thoughts on the whole deal. This is the bypass valve I bought:

I always liked the sequential HKS valves. They are pull type so pressure is always keeping them close under boost. You never have to worry about leaking, adjusting or changing springs/diafragms.

Turbosmart makes adapters from just about any flange to any flange and HKS makes 3 size recirculation fittings. Maybe a vendor could get you one close to the price of that push type vale you linked. Might as well get something you won't have to mess with again and will meet future possible power increases. Just a suggestion.

Fezzik, thanks for the drive! I still smell like rubber. lol

Hopefully those vids turn out ok!

Well break in is done. I did a couple of hard pulls. One of them I broke loose in 1,2,3rd gear and called it quits.

Hard to tell anything from a dark video that shows a navi screen wobbling around.

Fezzik · 10-30-2010, 02:04 PM

Sorry. It was the best I could come up with at night. I'll get some better videos later. Just thought u'd like to hear the sound at least.

I had the laptop in my lap logging data. The car is such a torque monster, I couldn't hold the phone steady. lol

Let me know how the billet valve works out for you.

I think "its a complicated engine" type comments would hold up better if the turbo kits for these cars didnt work fine.

The GTM SC works fine too. The fluttering is a minor issue that Sam is looking into.

That does sound like fun!

I think the fluttering sound is pretty annoying and for a daily driver it would bother me.

What you are missing is that the turbos spool slower so it makes it a non issue. The load point that the sc kits gets the fluttering, the turbo aren't building boost yet.

Just an update. Sam has been in constant contact with me. I've had a cold start issue and a heat soak issue. NOt a big deal, i just have to give it a little gas to start. Sam is also working on the solution to the fluttering and will send out a fix when he has it. I"m going to try to do a few more runs for sam to gather data if efuseakay is free
