more so than this sample test you refered to
many years ago buschur took two cars from his shop to switzers dynojet on same day. he wanted to see how low his dyno read. one dynoed 10% more and the other 18% more. 450hp car/650hp car. same day same dyno. kinda proved to me you cant just assign a percentage to a dyno that reads high or low.
However, curt brown isnt the only person who can make power.
people have made good power on small turbos... lets use this example, dynojet, bbk full, s2 cams on e85.
https://www.evolutionm.net/forums/ev...-bbk-full.html
so with my trusty $5- calculator; which sadly most americans dont use & have themselves in debt..... but that's another topic...
so this example made 552, add another 25/30whp from the R2 cams over S2's & now your at ~580.
This car was:
still running a maf, power limiter
bbk flows ~51 lb/min , which is less than a hta grn of ~54lb/min.
In my limited experience, I have observed about ~10/12% gain/loss in power with each lb/min.
so lets go in the middle of that, 11%, now we potentially found another ~30whp
now were tickling 610whp.
I dont know what the Pr differences between the bbk full run vs my hta run, but my guess, my set-up should yield lower, which is another power adder.
yeah, you'll most likely call bs to this, as you do quite often about other topics from other people.
Im just applying / stating what i see with the above dyno run.
Making big power on a small turbo is possible.
my pistons, porting to cyl head, im, everything else is different from your car, curt browns & the example from awd.
Turbo's are not the only piece of the puzzle in order to make power, you know better than that.

I can believe this no problem. I've personally tuned a CBRD BBK-B four years ago to 520whp / 510wtq on the GST low reading Mustang dyno, 2.3L, E85. https://www.evolutionm.net/forums/ev...brd-bbk-b.html
I don't see any problem with it making 540whp on a DD.
Nice work Aby.

cant comment on GTR power. I cant stand those cars and dont follow them. but many years ago buschur took two cars from his shop to switzers dynojet on same day. he wanted to see how low his dyno read. one dynoed 10% more and the other 18% more. 450hp car/650hp car. same day same dyno. kinda proved to me you cant just assign a percentage to a dyno that reads high or low.
I expect dynojet numbers will be 5-10% lower. of course i will have mad respect for you if it reads the same or higher.

interestingly enough, the mid range is elevated in the VD vs the dyno chart, which will be posted in a bit..
I should have taken a pic of the graph, but didnt = fail
I think peak tq on the dyno was ~44x, yet the VD claims over 500 @ 6200 during the 3rd gear pull.
I simply felt the need to point out a tq difference greater in error than the peak power # your hang'n your tackle off of

The loading differences will affect things like you mentioned above.

Tom, I have all the respect in the world for the Virtual Dyno tool.
The tool will let you know if a change either helped, hurt or didnt do a thing, when used correctly / consistently
Yep.
For me, the rpm rate took off like a 2nd gear, then it held onto something between a 3rd & 4th gear pull.
from 2500-7500,
the dyno pull took 7.166 secs
road pull took 4.744 secs
