Dyno figures are one thing, lap/400m times are another.

What is more important to you?

Just remember, dynos are different, stopwatches/timing traps NEVER LIE!!!

Food for thought.

Well, the traps dont lie thing is also not the best way to tell. Like my drag racing skill is the perfect example. I go to the track, and with zero changes to the car, I pick up 2-5mph between when I get there and when I leave. If I put someone who REEALLY knows how to drive in it, they pick up another 2-5 over that.

So trap speeds arent always the best indicator either. But they are typically more reliable than dynos. Since dynos vary so wildly.

That is something a lot of people also dont think about, and it affects you at ANY mod level.

Say you go stage 2 at 10,000 miles.

Then you put 50k more on the car. There is a 100% chance your tune is off, even if you maintained it. Most likely not majorly off, but you can definitely re-optimize to compensate for changes.

If you want to see big numbers - you can just dyno on a perfect weather conditions day, adjust correction factors in your favor, and make sure you use a high reading dyno.

If you're talking straight-line racing - the only thing that matters is timeslips.. and there is much, much more to timeslips than dyno #'s

I have 220 awhp from a catless exhaust(including uppipe) and an opensource tune from DSG, near me. They have a very conservative dyno (aka "the heartbreaker"). My car has high milage, so the turbo isn't probably spooling like a new one, but given that other guys in the proven power section have done high 12s to 13s with the same hp, I'd feel pretty comfortable saying you could make your goal at stage 2. Finding the perfect launch rpm appears to be the key as much as anything, it seems.

Even timeslips dont tell the whole story. Same car different driver can vary almost a full second and 5mph.

Personally, I use dynos for good tuning. The HP#s are just a bonus for me.
I care more about A/F safety and longevity of my motor.

Heck man take all 10 BONE STOCK and dyno them. 10-15whp differences are not super uncommon.

That and he could also be seeing the 2005 vs the 2006 wrx. 2.0 vs 2.5 ltr motors.

Some good points about how 1/4 times will change by the run. Air filters, thinning oil, Also tire wear. That tire with each burnout changes the outer diameter. Which can change ratios which will effect times.
