i have the pfab topmount tubular manifold and a t-3 60 trim and i cant seems to keep it under 10.5psi with a 3 psi spring in and this isnt even goin WOT. is this a common problem with their manifolds or any other top mount manifolds?

 

how do you know its at 10.5 psi, maybe something is wrong in your gauge set up

 

When posting questions it is very difficult for people to help if you don't list eveything you have done to the car down to the type of WG, EMS, turbo....everything. Then and only then will you get help, also many memebers will only help other members and not guests. So maybe consider getting a membership if you want additional high quality answers and help.

 

What ems do u have?

 

stock engine on hondata flashpro, 3" downpipe, no cat, 70mm single.
46mm wastegate, hks blowoff, 3" intercooler piping.

and hondata read 10.5 at 5000 rpm

 

what kind of boost controller?

 

PRobably running off wastegate

What type of wastegate

 

What's your boost cut set at? Post a screen shot of your datalog showing the boost plotted against RPM. Post screenshots of the timing maps too

A few things can cause creep but the main culprits are an undersized wg, bad wg design on the manifold, or too little timing. Haven't heard too much about the pfab stuff being creepy, so I'd assume its in the tune somewhere.

 

yes just 3psi wastegate spring, turbosmart 46mm

 

thats cool, i will see whats happens when i take it to get dynoed (hopefully tomorrow). ive just been playing with it myself and have it running smooth but like i said no WOT for this reason. i was just curious if this was common on p-fab manifolds because of the way the wastgate flang if 90'ed off the exhaust collector instead of Y'ed.
