Who here has actually had theircar to the dynotune shop? I'd like to do some gross comparisons. Mine has the mods in my sig and 264 awhp and 277 torque. anyone else car to chime?
 
Baseline 235whp
Add DTEC FCBC for tuning, +22whp
Add SRI, BOV, race pipe and ETS Tmic + 26whp (with retuning on DTEC).
Total 282whp-330ft/lb tq
Still left: Down pipe, cat back, upgrade stock turbo and possibly new exhaust manifold. Goal 350whp.

I'd like to see that slip? Did you dyno at Altered Atmosphere? How much boost? Advanced timing? Race gas? Temp and humidity?

you can't compare dyno numbers unless you were running at the same place on the same day.

i didnt know it varried on the condition?

does that mean on any given day you car could have more or less HP due to climate?


p.s i know nothing about dynos, engines....

thanks

yup, temp, atm pressure, all sorts of stuff affects your cars power


its good to know ...thanks

i guess thats why my car feels faster in the winter>?
 
yep, because the air is cold and less dense. Never noticed when its hot, its hard to breath? almost as if the air was/is thicker...well, imagine you engine trying to breath that. That's what the COLD AIR Intake does, sucks cold, denseless (<--is that a word?lol) air.

Well... just a quick correction, right concept but backwards a little bit... cold air is denser than warm air... here something straight from K&N's website...


"Cold air is denserheavier, if you willso it contains more oxygen molecules per cubic inch. The more oxygen there is available to your cylinders, the more fuel they can potentially burn."

So thats why during the winter your engine feels stronger, its got more air, so bigger bang, more power
 
Most of the posted numbers here are adjusted for atmospheric conditions I'll wager.

I dyno'd at MAC Autosports in Parker, CO (Denver) completly stock, 93 octane. 225 WHP, 282 TQ SAE corrected. BUT the real uncorrected number was 181 WHP!!!

All you guys should at minimum include "SAE corrected" or identify whatever correction factor is applied. Let's get the truthiness out.

If there was any reason to believe the stock turbo had the head room I would bump the boost +2 psi. That should compensate for the altitude.
 
If you are at altitude or tested on a hot/cold day I would be surprised if you did not get (or could not get) a set of corrected numbers that are significantly different.

So, in WV, I am guessing you are at some altitude, 1500 ft? If your numbers are truly uncorrected you should see what it compares to at corrected sea level.
