It has so much more in it looking forward to getting more fuel in it and turn up the boost more. Our goal is 800rwhp I think we can make it with more timing and fuel
Wish I was on that end, if I can find somebody to take my IWG that is what I'll be doing.
You told me about that, half bridge right? I'm hoping to break 600 @ 20lbs with E85 on my semi-peripheral. I'll be happy if I break 700 with my housing, but I'd love to see somebody hit 800+ with this guy in any configuration.

to each their own, but I think its bs and just another wad of the fake news social media hype sells tactic that that whole group employs
and nobody ever got confirmation from the tuner, who seemed to imply it was not a rotary. When I asked on another forum that was arguing about it, why abel couldn't say, he PM'd me pissed off I mentioned his name along with a bunch of obscenities and borderline threats. WTF...ok dude
that whole deal stinks. Crack 800 and you're #1 as far as I'm concerned

Yeah I saw that but personally don't believe it. Was posted on Facebook by that Abel guy who in that post said something about "no durritos in this car". Plus the fuel system on that car purely isn't capable of doing that, in any sort of configuration. Maybe running a 16.0 at WOT

one thing we can agree on from this Borg Warner comp map is that the 9180 will not make more air than 95 pounds/minute.
traditional relationship between air and power is 1.92 CFM makes one rw rotary hp SAE. this works well for raceports and bridgeports. peripheral ported motors make more but of course in a very narrow RPM range.
running the numbers, 708 looks like tops on the 9180 non peripheral.
the SXE 69 has a small flow advantage top end V the 9180.
as you can see flow is available around 100 as the rpm line is not yet vertical. flow at 60% efficiency is good for 738. both turbos share very close if not matching compressor wheels and the difference is in the 3/8 inch larger diameter compressor housing that was designed 3 years later.

how does the peripheral affect the calculation exactly? I'm assuming this is a change to the 1.92 motor and if so what world it be?
also how does the housing size affect the compressor map and pressure ratio? Does it not shift the graph to the right? I believe BW has a chart online quantifying the change with each housing size, but I don't remember.

Note the S300SX-E has a broader compressor map than the EFR 9180 with both a better compressor surge line on the Left and more peak flow on the Right as well as broader efficiency islands in between.
An EFR version of the S300SX-E just seems like a no-brainer decision to me.
Maybe BW just has a bunch of 9180 compressor wheels to move since IndyCar made Honda go twin EFR 7163 like everyone else?

The 1.45 9180 housing still outflows all of these, although the 1.30 Tial won't be far behind.
