Those willing to make that kind of investment tend not to bother with 13 or 15 class turbos (19T and TD05 options seem most popular for that crowd).

Hard as I haven't found any today and even looking back on former members who I thought achieved such numbers turns out they had engine modifications and not just bolt on 13g's/13c's.

Again, dyno numbers are comparable only when the runs are back-to-back on the same dyno with the same operator. What does the demand curve look like for
400 AWHP at 14 psi?
Trap speed seems to be a more consistent metric, as it removes many of the variables that impact dyno numbers and elapsed times. Speeds measured with the same model of G-Tech accelerometer
would be suitable for comparison IMO. Jack's runs were surely on race gas at higher boost, so this is just an example and not particularly useful for the 17 psi comparison I proposed:

13G's went 12.000 and 119.381 best mph, on 4/8/95; about 500 hp at the wheels; overall, gained about 110 hp with 13G over 9B, but given other changes 13G likely ~100 hp better than 9B.
13G best ET was 11.702 @ 118.061 on 6/6/96; this was through traps in 3rd gear, on the rev limiter. I was the first 3000GT in the 11's 5/17/95 with an 11.937@118.338. --I think 13G can be good for about 510hp at wheels maxxed out with standard stuff.

I have yet to see a satisfactory technical explanation that would substantiate the claimed performance differences at 17 psi. Perhaps it's time to move this to the
Advanced Technical Discussions forum to solicit additional input?
