Not seen any recent G35 dyno's but the G37's are around 330whp tuned now.

There are not that many HRs out there.. I think you should be quite satisfied with your result :)

07 Sedan G35 3.5HR Auto

HPS intake tubes with a pair of 2.7" ID MAF housings and a cheap amazon CAI kit for the filters and heat shields.
DC Sports Headers
Z1 High flow cats
Z1 High flow Y-pipe used as a start for a custom 2.5" dual exhaust with X-pipe and 4 magnaflows.
Stillen Underdrive Pulley
Ported 3.7 lower intake, upper intake, injectors and fuel rail
Uprev tuned by me
Gained nearly 30 hp and 40+ TQ in places of the powerband from cam phasing adjustments.

215K miles

326 RWHP and 282 RWTQ on a stingy dynojet

Car has been 12.6 @ 108 on stock size well worn Sumitomos. With me sitting in the car it scales about 3,800 lbs. Wallace Racing calculator shows it takes about 368-375 crank hp to run that ET and Trap speed. Lines up fairly well with a 12-15% loss through an Automatic. Car will haze the tires from any speed in 1st gear and spins the tires hard on the 1-2 shift and chirps 2-3.

The 3.5HR is only a few HP behind a 3.7 stock and mod for mod. I have a 3.5HR head 3.7 planned when the 3.5 expires someday. Or maybe a 5.3 swap. I built my exhaust with a possible LS V8 swap in mind knowing the V36 sedan has the beefy rear end, axles, and rear wheel hub bearings from the factory. I just don't want to LS swap unless I can find a way to keep all the factory stuff in place. Gauges, VDC, ABS, traction control, DBW, A/C and what not.
