In this thread https://www.rx7club.com/showthread.p...9&page=2&pp=30 "Zero R" (a-spec) says "Wargasm, he is running the larger 102mm 42R, it is about 4% less efficient at lower boost levels, than the smaller 94mm."
This would make the wheel 74.3 inducer and 102.3 exducer on the compressor side.
In https://www.rx7club.com/ne-rx-7-forum-30/little-taste-pfs-gt42r-476282/ "Zero R" said "Just so you guys know it is the smaller 1.01 A/r housing T6" which is what got my curiosity going about it.
So it's a T6 -footprint-, not a T6 frame center with a T4 turbine housing bolted on it? Interesting... Whatever it is, it sure does work!

Eh...sorry for the bad post...
Nice power none the less.

GREAT results Ernie!!! What does your fuel system consist of? I knew it would pass the 600rwhp mark @ 30psi 
. Do you think you can get a 4 bar map sensor and push it or are you done? I can't wait for you to get your launch dialed in to put down some SERIOUS TIMES!

Wow, great numbers Ernie. I hope that roll cage is comming soon.
What did Ray do internaly to the core other then porting ? I thought once you put down 500+ the stock eccentric shaft is prone to failure. As in twisting like a pretzel

Damn that does looks nice. I should have hung around a little longer to see it run on the dyno. What can be said other than Ray is THE MAN!!!
btw Thanks again Ray for spending the day sorting that mess out for me.

Ernie, do you have a cage/harness/window net/shaft loop/flywheel shield/extended studs/batt switch etc. etc. etc to make it legal? I'm sure tech will be all over your car with the trap you'll be putting up.....

Finally, someone with dyno data to back up the fact that MAZDA SEALS ARE THE BEST! ;-)
Seriously though, your car must accelerate so hard it wrings everything out of your lower intestines. I cant imagine driving it, most power ive ever driven was an FD with 434 to the wheels, and that thing was freaking fast (for me) !
Good job, i hope it holds together for awhile!
