hey hey, I am going to be order my Helix Catted DP here shortly and was doing some reading on a few sites about boost creep. From the sounds of things it looks like it occurs more frequently in the colder weather. My TBE will be helix catted DP => Perrin Catback Just curious if who all has had issues with boost creep and what you were running in regards to Mods. Looks like a Port and Polish may be a band aid to work around this. Just tryin to do my research before I make the purchase. Hopefully the Catted DP will be enough to prevent this. Any other feedback etc on this would be appreciated... I have been googling around for a while now.
I didnt have any problems with creep on my catted random tech pipe. I have heard of creep occuring so its not out of the question but normally on non-catted cooler climate cars.
The only problems ive heard involving boost creep has been caused by downpipes with the factory style flange w/no provision for flowing wastegate gasses smoothly. As long as it has a bellmouth (which the Helix pipe does) or similar style piping at the turbine outlet you should be good to go.
if u get boost creep just get ecutek and upgrade to a superzilla and u should be fine jokes aside, in most case ecutek alone can fix it
well then, u need to keep watchin the boost gauge when u install the DP... that will keep ur eyes off the road and increases the chances of an accident... if u get ecutek'd, then u can keep watchin the road... she'll understand ur doing it for ur own safety
yea boost gauge is a good idea. all turbo cars are gonna have a little lag i think. im sure your wife would love to know you need 850.00 worth of more stuff Keith hahaha..
yea worst case senario you might have to port the vf39 on the downpipe side..nothing a dremel cant handle
I thought that most boost creep occured on cars with a hi-flow exhaust and no cats? I don't know that I've ever read about it happening on car's with a hi-flow cat. Otherwise, I agree, Ecutek that thing and worry no more.
Acutally, I don't think I've run into any yet. Now, I've not been catless during the winter months. So I'll be watching it (as best I can while driving anyway) to see. I hope to get Ecutek'd myself sometime real soon though. I also seem to remember reading that the exhaust side of the turbo had something to do with it. I believe that Subaru changed it mid-year of the '04's.
