Ok guys I need all of your help right now. So here is the deal. I have a Drag gen 3 kit on my Type R. Tommorrow I go in for HONDATA! Which also includes 4-5 hours of dyno tuning!

But here is the problem: I am boost creeping bad! I have a delta wastegate that came with my Drag kit. I just put the lowest psi spring (the green one). It is supposed to boost 3-5psi, but no..... mine goes up to .69bar or basically 10psi!

I have a 3" downpipe and 3" exhaust all the way back. So I expected it to be a little higher then 3-5psi but not 10!

I have the wategate plummed from the compressor, to the side of the wastegate.
I have the AVCR boost controller, however it is not hooke up at all.

This is the EXACT same kit I had on my LS integra and it NEVER boost creeped/spiked.

So any ideas on how to keep the boost from spiking? I need to know soon cuz i am going to the dyno tommorrow!

Thanks
Chris

PS- Is it possible I am just flowing to much air for the delta to handle? maybe its time for tial..

 

yup.. TIAL

shitgates have a 100% eventual failure rate

 

are your hoses new ?

i'm using a tial wastegate and i had the reverse problem of yours. I couldn't boost past the spring. So i upgraded to b igger hoses and the problem went away.

 

Let me know if you need a Tial wastegate. You can pick one up from our warehouse on the way to the dyno.

 

Ok, just ordered the Tial. I hope this solves my boost creep problems.

 

it will...

 

you can also get boost spikes from a leaking/cracked turbo manifold you know...

 

Where in SD are you getting the hondata done at? what stage and how much? just wondering cuz i'm seriously considering going that route, and i'll probably be moving to SD soon! let me know! hope it works out for u

 

Try one of these. We ran it up to 16psi and it held perfectly.
