lets talk turbos
lets talk about trims ar turbine wheels ect.....
here is a picture of two turbos that are of the same model except the turbine wheel in the one is a p trim and the other is turbonetic's new F1wheel. the exhaust housing are the same minus AR. look how much more the turbine wheel is recessed.

the turbine wheel on the right is very aggresive. its much wider then the one on the left. an aggresive turbine wheel i would imagine would be flatter then on that has alot of pitch.

still learning a lot over here but here's a stab...
It hard to determine....many variables...mass of & wheight of wheel? Are the pitches of the wheels similar, are they progressive or fixed? Is the progression comparable? Amount of blade overlap?
The one on the right definately seems more agressive..but without some of the above info it would be hard to say
From my jetski racing days I was amazed how much a few degrees with the right pitch progression made on thrust and overal pump efficiency. More overlap definately helped low end thrust but at the cost of top-end pump efficiency....I would assume the same characteristics here

Simple
A. The one on the right will produce more.
B. It cost more money.
If I told you the real answer I'd have to have Lisa cook dinner again.
I know but you have to call me to find out if you already don't know.

Looking at a picture doesn't tell much. You need to measure the wheel diameter and hight to get any sort of idea what you have sitting in front of you. That is only half the equasion as you need to know the pitch or degree of the wheel in comparison to the other etc etc etc. I would call up turbonetics and speak to their head tech
Are both turbine housings the same A/R ?

I think the one on the left looks like it would make more HP. I think you got sucked into the "F" wheel crap.
I would install the old units. I dont mine testing out the new units for you........plus the one on the right is way to big for your wimpy stock cubed motor!!!!!!!!!!!!!!!!!!

i really dont know what iam talking about:o :o :o
i started this tread cause i wanna learn...
ok...F1 isnt any specific turbine wheel its turbonetics new version of a turbine wheel. the wheel on the left is old school turbine wheel the on the left is the new style F1. the AR on the right is also .86 were as the the other is .68
