Boost creep

ASSISTANCE Forced Induction
1

Well, i dropped my car off to get tuned a couple of days ago. I got a call yesterday from the people saying that my car is boost creeping really bad. My setup consist of:

Sfp mainfold
Tial 38mm wastegate
T3/T4 .60 .63
2.5 inch open downpipe
1.25 inch dump tube

The tuners seem to think that it is the dump tube that i made. I made it out of some stainless stell flex hose, and i had to bend it a couple of times to get it the way i wanted. They say it is too restrictive. I guess it is a combination of that and the open downpipe. What do you guys think?

Could be, unbolt the dumptube and see if it still creeps. :shrug:

They made me a new dump tube and it holds boost fine now. Its goin on the dyno monday morning, so i will post up some numbers.

Post where you got it tuned and the map…what management are you usng?

tuned at l’orange automotive(www.tunedbylorange.com) in Niceville, florida. Im using a walbro fuel pump, rc 550’s, and Hondata(No comments). Im not sure what map they used, but i will post all of the sheets i get next week. Car was street tuned at 10-11 psi on a stock b18a, will be fined tuned on dyno monday.

I think how its funny that when the DIY stuff first came out, people used to put that “no comments” caveat by it…now its people putting no comments about Hondata :slight_smile:

The only reason i did that is because i dont want someone to say, “Why didnt you go with uberdata?”. Im so sick of these arguments about uberdata or turboedit vs. hondata. :up:

In the end it doesn’t matter what costs less or mroe or what is better or worse. It’s all personal preference. Good to see they fixed the boost creep tho. I was gonna say 1.25" is kidna small especialyl if the dump is long. I usually use ATLEAST 1.5" ID piping
