boost creep vs turbine housing AR

[Parker]

Some people need to learn how to read..... Wow.....

[TsiTom]

Based on the question, I say increase it

[Grr]

wow, what a dumbass, increase of course

[Bookem]

Bigger is always better, no matter what...................

[zbrown]

Ok gone on long enough

I had argued that increasing would, for the above reasoning

the other FS member argued decreasing it would for the above reasoning

not gonna say who it was unless he wants to say something or argue his logic here in this thread

haha, i will say i was wrong based on your response's. but i still think for the car me and zac talked about. it would have fixed the problem. but might be bad if generalized for every situation.

[Parker]

so, what car?

[DrifterExtreme]

it was a civic with a ls motor. running a afi turbo kit, 57 trim 60/63, v-band 38mm gate.

guy was trying to run 7 lbs and was creeping to 10-11 lbs. Also he is running stock redline 7200 and map sensor.

So i had mentioned switching to the small a/r as it will spool sooner and help wastegate flow. all the larger housing will do in this case is slow down the turbine and increase lag.

So there might be 2 ways to go about solving the problem. but in this case i think the smaller a/r is the way to go.

still think it is crazy it makes 4 psi without the wastegate on at all.

What car was that? Honda-Tech?

[DrifterExtreme]

yes it was on honda-tech

that has some serious flow issues through that wastegate elbow then. Thats nuts

funny thing is it is a afi ramhorn. pretty standard manifold. so i think this guy is smoking crack, or something is up
