Thanks for the reply, I have read that thread, but it really doesn't answer my question as to if I will be falling off power at higher rpms with a 4g64.

Is the 2.4 gonna fall on its face like a 2.0 with a t25, no. Would you make more power with a bigger ar hot side compared to .55, yea

"Will the .55 mitsu housing choke my top end? I know it limits flow to around 50 lbs or so, but unsure if it actually hurts on top end power"

It hurts as much as the max flow your losing by using the 55, id go bigger considering the amount of load your gonna have in a 4x4, seems like your thinking v8 terms with horribly undersized turbo

An hx35 with a twin scroll is a great combo with 2.4 but do not expect hx40 power up top at all

Just seems like a reduntant answer that is revealed in that thread, spool or airflow. Pick one, how do you drive your 4x4, WOT mudding? Go twin scroll or big t3, low rpm torque need situations? bep

maybe I missed something, but the .55 is suppose to flow around 50lbs a minute, and an 8 blade only does 52.

I dont care about the 2lbs, but im assuming at some point past 6500 maybe there is a restriction with the smaller hot side and flow will drop off. I was browsing the thread with my phone and didnt see any dynos. but that threead is all over the place. Most people are looking for the absolute most hp especially with dsm, im looking to see if I cant get a bit of both, fast spool with some top end. If it is going to fall off, I wanna know where, this is what I would like to know. I have valvetrain good for 8400rpms, if I can get it up there somewhat even close to 8k with a .55 housing I would like that.

the truck probably only weighs 2700lbs, and wont be in 4wd very often, it's not a wheeler, just a fun project that should be functional, as to why im looking into a hx35/bep combo as it offers better spool than a e3 16g from what I have seen.
