everyone says the batmo is better for spool on a stock turbo but then again that's going from a cast wheel to a more lightweight wheel..
batmo turbos, fact or hype?

Didnt danville post dyno results switching from billet 475 to bmw475 on a 2.6 tk on another forum?
Maybe someone knows where

Wouldn't the Batmo wheel weigh more than a standard Billlet? I would think you would have to leave more material when machining a batmo in order to have the curved blades? This was my thought when I opted for the standard billet over the batmo.
On another site i read that the batmo actually slowed down his truck compared to a billet wheel. I will have to try and find the post but i beleive he said he lost a tenth almost. I believe it was a stock lbz turbo

2.5 mafia 1k hp.
they shouldn't have to make a tuning change, that would change results correct? so if you change tuning of course it will spool better..
i don't think comparing how it functions in a stock LBZ turbo is helpful to determining how it would work in a 475 application. it may be though, just the way I look at it
What were the turbine sides of each? not all the power is made from the size of the of the compressor wheel!
BILLET vs. BATMO NO TUNING CHANGES..that's the only way to settle this..no one has anything on paper so myth busted, batmos aren't worth the money until proven..
waiting for someone else to give me a quote first:thumb:
thought i read this to, but it wasnt on a stock turbo. also was told that one of the "fancy" covers bullseye has lost hp.
to me what makes a bat mo worth it is the price. you get what you pay for. i know that a cloumbus charger or even something with a harts wheels is going to make more power, but at twice the bill. if a batmo is making the same kinda power with a run of the mill billet wheel s400 turbo, then to me its a simple decsion. i just want to know if it is before i drop a chunk of change on one. if its with in 50hp of and expensive turbo, it might be worth saving almost 2k then.
also, i have seen some names of people that i feel know something about turbos reading this thread, but none have posted...i think theres info out there, good or bad, but no one is posting. not calling anyone out. could be wrong, have been often lately.
Columbus has a "few" new billet test wheels out showin huge power increas over there old billets in there 4.1", 4.2" turbos......never guess what the wheels look like!
