I can tell you guys this, these wheels aren't the same. I just tried the bird carcass test & it didn't eat it. Damnit! They really test those wheels don't they? Wow!
alright so wheres the billet gtx series bat-mo wheel?
I just don't see how a 66mm out flows/performs a 75 mm ???????????
Exactly, I asked in another thread what the exducer of the "66mm batmowheel" is? As presented it would be easy for many to assume a true 66mm (i.e. s300) batmowheel is flowing nearly the same air as a 478 lol.
Yes it was a 66-100mm comp, 87mm exhaust, with a 1.10 housing
The only thing we changed was the compressor wheel.
Sorry Nick, I forgot to reply on that other thread Nick
No worries, thanks! So that wheel is shaped a bit differently then the standard equivalent I would assume given I believe the standard 475 ETT wheel has an 102mm exducer. That right?
Yes that is correct
I hope we see some flowcharts soon.
For them to mean anything they need to test several known wheels and see those also.
The testing they did on Arons truck was definately awesome, but what works on one dont work on every truck. I am ppumping my truck the minute Zach gets a cam on my doorstep. Once I do, I plan on testing on the track. I'm having a S480, S475 built to test as well. I know the batmo 66 flows on the compressor side, but the turbine side will probably become my restriction if I reach my goal.
You had said flowcharts. For the flowcharts to mean anything on this batmo several known(OEM borg, garret, with OEM maps) will need to be checked on the same test bench.
I have seen x turbo manufacturer claim their 68 would flow nearly 110 lb/min, where borg rates the s480 at 120 lb/min. When I questioned them on it, I was told "well borg underrates their wheels" While they may or may not be the case, that is what most of the users will base their comparison on.
Testing it on the stand will eliminate the turbine variable, porting variable etc. Also testing it on an inertia dyno is subjective also. I have seen Jim Bo's xxxHP cr get the whooping put on it by a 200HP less Ppump.
I'm not buying into the batmo until legitimate results prove they are a more efficient compressor when compared to a standard wheel of the same dimensions.
One of the top 3 in 2.6 at TS has a Batmowheel...
So it must be the 3rd place? LOL, if it was one in the top 2 it would have been the 2nd.
