^^ With the STD correction, my car is making 362 rwhp according to my tuner.

This was based on my 351.5 rwhp / 375.0 ft/lbs of torque run.

My second run at the end of the day (without the A/C on. FAIL.) made 353.6 rwhp / 373 ft/lbs of torque.

Doogee, that could be the car going rich when letting off the throttle. My car did it when I first went WOT and when I let off. Or it could be the valve stem seals like the other person said..

And nice numbers Steph.

If my engine was back together we could see if I can break the 200whp N/A mark with all the parts I have laying around.

What's the conversion percentage you used to determine STD?

You cannot simply convert numbers from SAE using a percentage number.

SAE takes into account ambient air temps, humidity and other environmental factors to compensate.

If it were Valve Stem Seals, wouldn't I be burning oil?

I didn't lose a drop after an entire track day yesterday.

^When I did a dyno last year I noticed the same thing; the car would puff out a bit of smoke in higher RPM. The tuner at the shop there told me that its a good sign, something about the vanos being healthy... not sure how true that is, but that's what he said! so might be normal

I think on a day like Sat. The STD and SAE would be pretty close. The air was cool and dry. I don't see more then 10hp+/-

It was either that or an excessive amount of fuel can also produce white smoke (yes normally too much fuel is black, but there are instances where it would be whiteish).

I'm guessing you have a tune?
