12.6 - any other mods to consider?

[metroplex]

I cleaned up my tune and I tested it at the track yesterday at the last open test/tune for the season. I figured it was now or wait until April.
The best for the day was a reaction of 0.139 (Sportsman tree), 60' of 1.864, 1/8 mile 8.185 @ 86.12 mph, and 1/4 mile in 12.66 @ 106.98.

The only mods are those I listed in my signature. I have the original factory (3 years old by now) dirty paper filter that I tapped out or vacuumed every year or so, and the original factory Badyear Eagle RS-A tires with over 23k miles on them that may or may not last this winter snow season.

Looking at the timeslips posted on Dragtimes, it seems the SHO's running from 12.4-12.5 all have cold air intakes, downpipes, cat-back exhaust, and tunes. The SHO's running 12-12.4 add WMI, and the ones faster than 12 seem to add bigger or upgraded turbos.

Is this accurate? If I spend the $2800-$3000 for downpipes, cat-back, and a CAI, I'll only look forward to 0.1 or 0.2 seconds faster in the 1/4?

Seems nowadays the hot button is fueling.  Is your 12.6 with 93 or ...?  E30 (or some E blend higher than 10), or race gas could be one approach, if you only want to set a record rather than drive around on it all the time.

I'm running 93 octane (probably E10 since it is Michigan). It's a daily driver, so I'm not planning to blend my fuels or go to race gas.

Well, you could do it just for the track.  Now if you are planning on upping the DD performance level, then yeah, downpipes, meth injection, and bigger turbos would be the way to go.  Bigger turbos might even be 1st on your list if you want a single mod that doesn't mess with fueling.

You could do all that or just do a 75 shot of nitrous for way less if it's just for the track.
Granted I sell those parts but honestly if it's just for ET then nitrous is much easier and will get you the same performance gains, call it turbo upgrade on payments.

No mods other than tune, k&n filter here.12.4@110.9 But I run e20 tune all the time. Gas station right up the street has e85 and 93 in same pump so it's no biggie to mix.
