General consensus on boltons to gain the most HP.

Jordo!

It depends on the dyno -- some are adjusted to read high or low more easily than others.

Dynojets are very consistent, because the weight of the drum is a fixed variable, unlike the degree of load that can be adjusted on some
other dynos.

That said, those with adjustable load are better for tuning.

For a comparison of different kinds of dynos on the 350Z, see here Turbo Magazine's Dyno Dash - Tech Review - Turbo Magazine

and for a table that summarizes the % change, here
Dyno Comparison - NewCelica.org Forum

Stock 370's put down about 273 +/-5 on a dynojet with SAE correction. Drive train losses appear to be around 16.5 - 17.5%, with no clear difference between AT and MT.

Stock Nismos put down around 288-290 +/-5 (need more data to verify). My guess is that the difference is mainly due to a different VVEL tune, as they always seem to make a bit more than regular Z's with similar mods and similar fuel and spark tuning.

Tell me your mods, and I'll tell you what you'll most likely come in at on a dynojet with SAE correction. If I'm wildly off, I owe you a beer

Based on the data I've collected and after reviewing other dynojet dynos, it looks like you need LTH, pulleys, AND a tune to creep into the 310's. Everyone else with full bolt-ons and a tune should just about break 300 +/-5.

More should be possible once VVEL can be tuned.

Check out my dyno thread for lots of details and commentary on the effect of various mods if interested
