i have a few questions about boost creep. on ac equal length mani (that uses an elbow to clear all ac componets) how much boost can you make with a tial 38mm before you see boost creep. i know that the elbow and small wastegate and factors in boost creep.

beepy

12.14651698 pounds-force per square foot divided by 144.


But really, there are dozens of factors that affect boost creep. This question is impossible to answer.

does any one have an ac compatible equal length + tial combination. if so what pressure did you start to see boost creep, i am looking for someone that has had eperince with a similar set up

Dude, you at least need to tell us what turbo you have, and what engine it is on.

i plan on having 400hp on the street at 16 psi (which i think 38mm would be fine) but if i ever decide to turn up the boost 44mm will be neccessary. i was just wondering if anyone had a ny personal experince with a similar set up

downeyballz

just because it worked for their set up doesnt mean it will work for everyone. i did ALOT of searching and most people running high boost usually go with a bigger wastegate. when searching i didnt see anyone with a set up simalar to mine. im looking for someone with experince with the same manifold

Not AC, but this is just an example of what I was hinting at. If it were MY car with this manifold, I wouldnt use anything smaller than the 44mm. The 38mm will probably work just fine at 1bar+, but I wouldnt want to take the chance.

ITR206 had the same thing, but comparing the 40mm to the 44mm. The 44mm cured it if memory serves correctly.
