ok, your right, a 6mt will gain 3-5 % of the 53whp total gain, thats 1.59 to 2.65. you're really splitting hairs here. fact of the matter is, the vhr responds significantly better to mods than the hr

an hr with the same mods would gain about 30 (if that) whp, this gained 51, thats 20 hp more, thats significant in my book. how about you do a test for us, you already have hfc's, so don't put on your injen before the exhaust. then we can all see the gain. btw, how much did you gain over stock with the hfc's and tune?
also, on a side note, A.H has test pipes, this guy got hfc's...

Well something isn't right then. This guy has more mods, but no tune it seems but has 51rwhp gains.
Here is another 370z with these mods and it did 54 rwhp.

Good explanation here: Copy and Paste:
I think the 5AT found in the Z is relatively efficient, when compared to the 6MT. Since most 6MT HRs dyno around 265-270, and if you convert the 306 crank hp of the HR to the old standard, which is around 313-315hp, the 6MT has a drivetrain loss of anywhere from 14-16%. The 5AT HRs seem to dyno around 250-255, which under the same standards as the 6MT calculation just used, would represent around a 18-20% drivetrain loss.
On the OP's dyno, if all else were kept equal, and the only difference being the transmission, the 6MT would potentially read about 2-6% more. Anywhere from 6-19whp more. If you pick the middle percentage of 4%, it would equate to about 12whp. Keep in mind that this only applies to this particular dyno.

Also A.H gained almost 60rwhp from his mods on a auto. So how is that less than the VHR?
