yea it must be since stock hemis run in the 15's!

Ronnie lives at High Altitude.... Thinner Air... Slower Times... True with any ride.
Put his truck at Sea Level and the times drop like a rock...

I know all about high alt but i still cant see a srt running anywhere near 15's......

Exactly......this is one reason why you hear claims of a vehicle being faster when it shouldnt be. Take a Hemi truck to a strip that is at sea level on a cool day and it might turn high 14s vs an SRT10 running high 15s at a track 6,000' above sea level....temps make a big diff too...

No, not an error.
A new 427 Camaro here in Calgary runs mid 14s, several SRT-10 Quad Cabs run low 15s (mine was one of them). SRT-8s with a few mods: 13.8-14 flat. Gen II Vipers, with a few mods: low 13s. New, Stock Hemi trucks 15.3-15.5. Older Hemi trucks 15.7-15.9, 400+ h.p. Vettes: 13.8s, 500+ h.p. Vettes, 13 flat, etc. etc. I should be posting m.p.h. as THAT is the true power indicator, normally, but since we are talking e.t.s....
I have posted this MANY times and unless you experience first-hand what a 5500 or a 6500 foot D.A. does to your performance, it is very hard to comprehend. Just driving 200 miles to the north of Calgary is a track in Edmonton which is 1000 feet lower. That automatically gives me 4 tenths and 4 m.p.h. So currently, 12.9 here in Calgary; 12.5 in Edmonton and a realistic 12 flat or high 11 at a sea-level track; all without changing a thing...And conversely, guys pull their hair out when they run a car here in Calgary after racing at a lower altitude facility. I've seen vehicles drop a second and pick up TEN m.p.h. between Calgary and the west coast.
You won't see any records being broken in Calgary and you won't see any in Vegas or Denver either. Sea-level tracks hold the records.
With a good D.A. at a sea-level track you can even get into negative numbers. Just ask Trainman, he knows all about it and the ones (like him) that pay attention to conditions are the ones that get the winning times. Make a few passes at a sea-level track when the D.A. is say 600 feet BELOW sea-level and the vehicle is gonna rock...
Driving from Calgary to sea-level on a typical day is like bolting on a 3 p.s.i. supercharger. As a Roe is 5.7 p.s.i., you begin to get the idea of what kind of performance gain (or loss) altitude can play...
For example, our Shelby (GT500) project car, gains a solid 3 p.s.i. of boost on a trip to the coast.
Any supercharged vehicle we have built here won't make advertised boost either because these kits are designed for sea-level. For example, a 10# s/c kit will see 7 p.s.i. here.
The t.t. 'Stang (Outlaw Street, Drag Radial) car will see 44 pounds of boost here and 47+ at sea-level. It won't quite hit 200 m.p.h. (199.7) in Vegas, which it will exceed at a sea-level track.
You lose 3 and 1/2 % of your power per thousand feet you climb or for every 1000 feet in Density Altitude, as conditions change.
There is just NO way to compensate for it effectively. And of course even the forced induction engines suffer, as mentioned.

Wat about replacing cats w/ cutouts... Any ideas?

Well, I'm an n.a. guy myself.
It is almost too easy to obtain big power these days with turbo kits, nitrous and such and it is fun and all but-
It is the fast n.a. ("All Motor") vehicles that impress me the most (regardless of brand) and tend to stick with me over the years...but that's just me...

K&N, Cat Delete w/Flowmaster, SCT Tune....Haven't dynoed but you can FEEL the difference, not to mention burn a lot of rubber with the torque control off:rock: :rock: :rock:
The plus side besides a little chunk of horsepower is that mine went from 11.8 and 12.2 mpg at 60 miles per hour to 16.8mpg at same speed- that was primarily the tune though. :rock: :rock:
