It's probably normal and Im not really toooooo concerned... but I figured I'd ask.
I was running the yellow spring in my DV with one shim. It felt very weak, so I swapped it with the blue spring. It feels much better now. However, if I go to accelerated pretty hard and change my mind (the boost climbs about half way and then I release the gas) I can hear the DV "sputter" for a second... is that normal? lol

Also, I can hit 24 psi of boost in any gear (other than 1st) by like 2300 rpms... I should probably adjust the onset on my BM huh? haha

 

Your explaination is a little hard to understand. You mean you get "futter" at low boost, (<10psi) that is normal for many dv/bov's. Holding the higher psi is the more important thing. I guess since you are seeing more boost means you have found the right spring. You dont HAVE to change the onset of your boost. You have a small turbo and thats what they do, spool early. So if you do, you just shortened your powerband.

**one final note, if you have 20+psi by 2300rmp's, YOU CAN'T CLAIM YOU HAVE LAG EVER AGAIN!!! That is withen 200rpms of a ko3(s).

 

You know... you're right. I guess it wouldn't even be considered turbo lag now that
i think of it. The thing is... even though my boost jumps to 20+psi at low rpm, I still don't start to get "throw back in the seat" pull until about 3k-3.5k. so yea, I have to say, I guess I was mistaken. It's not turbo lag, it must just be sluggishness getting the RPMs up to powerband level.

 

how many turns do you have the onset at? mine is at 1.5 turn and boost turned at 5 i keep my peak around 21psi no more. i want my k04 to last till i go big turbo in about 2 years....

 

24 is not going to kill a ko4

** Before someone asks... Its the making the turbo hold the boost far past what it can that will wear out the turbo, not a spike of 24psi.

 

this is true...but i like to sell the old stuff off my car so i try and keep it in the best condition possible.....pissed my step dad threw away my old rear sway bar....i could have gcotten like 50bucks for it...lol....figure a used K04 with little shaft play(hopefully) could be worth at least 150 bucks or so.

 

$150 is about what most stock turbos seem to go for on vortex. But agreed, selling stock stuff is a great supplement for new parts. Got my wilwoods for ~$900 and offset that by $225 for the sale of my stock brakes to someone with a regular gti.
