Hi,

Can anyone point me in the right direction on where to buy one of these? I'm installing a midpipe and I'm going to use some restriction, I was thinking 2.5"

Instead of welding a plate into the pipe, I'm going to use a 2.5" metal gasket plate and sandwich it between 2 regular gaskets between the midpipe and downpipe, but I can't find anyone that sells it

If anyone has any tips or recommendations on what I'm doing that'd be great too

 

You can make on or see if "JyRO" here on the forum is still making them.

 

Thanks I'll ask him

Do you think a 2.5" restriction is enough or should I go down to 2.25" ? I'm running stock turbos with dp, catback, mp, intake, and power fc

 

You'll just have to play with them and see. For some people, 2.75" is enough. Every car is different.

 

One more quick question!

I just installed a midpipe and a restrictor plate (I went with a 2.3" inner diameter plate to play it safe), and I put the plate between the cat-back and midpipe.

It shouldn't matter which side of the midpipe I put it at right, whether its the cat-back / midpipe or the downpipe / midpipe ?

 

Just take it easy at first, if you get no creep at wot in this cold winter air then you should be good to go with where you have it installed.

 

Yeah I'll lay off the high revs until I know for sure...

Is there any effective way of knowing if you're creeping or not before it's too late? I don't have a boost gauge and I'm still trying to get used to the PowerFC commander's read out... but being in atmospheric pressure and not instant is kind of weird

 

Ya, just watch the commander as you are testing it out. Press the up arrow to check peak boost.

 

i think 10 psi on the commander is like 0.7ish, but you really should have a boost gauge. Also you could have tried no plate starting out to see if your car does creep, then if you notice it creeping put in a larger plate and progressively get smaller until you have no issues anymore. And yeah dont give the car full throttle at first just ease onto it and work your way up to full throttle while carefully watching the boost pressure. You should be able to catch any creep before you have any problems. plus with the power FC as long as you have safe maps at the higher levels it wont hurt anything as long as you dont let the creep get out of control.
