I havent found out a whole lot about that IHI RCH7 except that it came with the older greddy kit, and its near impossible to get parts for. Looks like its maxed at about 375-400.

And do you have a comparison of boost levels versus rpm before and after the BNR?

no because my car ran like crap before i swaped the turbo over to the bnr, nothing related to the turbo itself just the car was crap.
im waiting for a new radiator to come in. as soon as it does, ill take a ride with my laptop and record the boost patterns off the microtech and post it on here.

I hope this helps.. I managed to find a compressor map for the IHI series of turbochargers a long with a few more sites for rebuilding and selling parts for this turbo. I have no idea how to read these things so someone else will have to chime in here..

My car has had stock turbos, BNR turbos, and now a full single. I think I know what the differences are.
Dont get me wrong, Bryan makes a great turbo for those that dont want the hassle of going to an aftermarket manifold. Just dont get fooled into thinking they are not without some penalties.

#2. My garrett turbo has the latest and greatest technology to help boost more efficiently which garantees lower intake temps.
#3. Four or five repair shops nationwide is not what I consider blanket wide support.
Looks like the turbo flows about 69 pounds at 2.6 ish bar.
What turbo you all put on your cars is up to you, but I personally dont mess those types of turbos.

Other then that.. How does it seem likes it flows? Would it meet the goals this guy is looking for? I have no idea how to read that compressor map so I wouldnt even be able to tell. Is flowing 69lbs at 2.6ish bar good?? Thanks J-rat.

69 pounds would equate to about 600 horsepower on a rotary. 2.6 bar is about what.. 41 pounds or so? Doesnt seem like a very efficient turbo to me. Will it make 375 on a rotary? Probably, but thats about all you would get out of it unless you want to run crazy boost.
FYI, I got the numbers from my buddy Trevor. I cant read maps as good as him yet, but I am learning.
