Is my turbine and compressor wheels too small?

I was just thinking last night, maybe the A/R of my turbo is different than a normal one.

I saw on prothe's website in a pic of a new vnt the intake A/R was .42, mine is .48, my exhaust A/R is .65....I know nothing of what those numbers mean. I do know it changes when the boost comes on, so I's thinkin' the boost will start out of the range I ever go. I have ran it floored up to about 4300rpm and still get nothing worth mentioning.

14 sounds better. but its still sick.
you should be making enough boost to grenade that engine.
should have a head shaped dent above the engine from so much boost.

im pretty sure you need the right turbine ahd compressor housings to go with their respective wheels. could be wrong, but i always thought they were matched. i thought you couldnt run a .48 wheel in a .42 housing?

Sorry I mustuv wrote it wrong. I meant the 14 is what I was pumping into the intake mani to check for leaks.

Not sure, I thought it had something to do with the shape/volume inside the housings, I hope somebody who knows about this pipes up.

well, thats good that your engine holds boost. at least you know your problem is turbo or intake related. too bad your rabbit wasnt better at compressing air.
