370z 7A/T dyno with Stiller Gen3

nis350

20 rwhp a huge gain for a stock motor with just an intake. I get that it draws cooler air being outside of the engine compartment, but that effect will diminish once that car gets up to speed as cooler air would push through the openings into the OEM intake.

I suppose it would be more accurate in the dyno comparision if a fan is placed in front to simulate speed of 40 to 50 mph.

I've never seen a dyno without a fan in front of it to do just that.

yes, but that depends on whether it simulates the airflow at that speed.

Just briefly read some old posts by Jordo and he posted the following stats with his mods:

Bone stock = 219

+K&N panel filters = 222 (+1.5%)

+Test pipes = 232 (+4.5%)

+S-tune catback = 235 (+1.5%)

+HPS intake tubes = 238 (+1.5%)

+Tune = 244 (+2.5%)

Cumulative gain @5252 RPM from Bone stock = 25 (+11.5%)

So 20 RWHP gain with just the intake is quite amazing....

Yeah, but it's not 20 whp just from the intake. Unless it was re-dynoed on the same day, then you've got some weather/ temp variance there. Then, the dyno isn't dead on the same two runs in a row. Realistically, it's more like a 15 hp gain.
