shobiz Posted March 14, 2013 Report Share Posted March 14, 2013 So I installed an app called Dynolicious on my iPhone, and did a 0-65 launch this morning. Conditions 4,990' elevation, 40F, dry and clear, 48% humidity, 2 gal fuel, car empty except driver (250lbs). Launch at about 2300 rpm. RESULTS Acceleration 0-10 MPH: 0.68 sec 0-20 MPH: 1.28 sec 0-30 MPH: 1.89 sec 0-40 MPH: 2.52 sec 0-50 MPH: 3.35 sec 0-60 MPH: 4.32 sec Elapsed Time 60': 2.17sec@33.2 MPH 330': 5.48 sec@68.7 MPH Max Acceleration: 0.77 G's Peak Horsepower: 363 HP I think most testers have seen a 0-60 in about 5.0 at sea level, 70F. I'm at a higher altitude, but lower temp, so I don't know what the difference would be? Seems a bit optimistic to get that good a time in a stock, non-PP 2011? :noidea: Quote Link to comment Share on other sites More sharing options...
bigPelo Posted March 14, 2013 Report Share Posted March 14, 2013 Cool weather + low humidity make the turbos happy. But 4.32sec is very quick anyway... possible? Quote Link to comment Share on other sites More sharing options...
yowen2000 Posted March 14, 2013 Report Share Posted March 14, 2013 I imagine this is measured with an accelerometer inside the iphone? Was the phone mounted? If so, did you calibrate before doing the test? I know that in the torque app for android you have to calibrate the phone if you change the angle at which it is mounted. 4.3 seems a bit too quick for stock...

shobiz Posted March 14, 2013 Author Report Share Posted March 14, 2013 It was mounted, but not calibrated. I need to figure out how to calibrate it. Quote Link to comment Share on other sites More sharing options...
83racecrew Posted March 14, 2013 Report Share Posted March 14, 2013 If the car is stock, it only has 365 HP at the crankshaft, which means it has about ~280HP at the wheels. I don't know anything about that app, but in Torque you have to enter the weight of the car along with anything it is carrying to get HP/Torque numbers. Did you have ~4600 lbs entered for car weight? Published tests for 0-60 are right around the 5.2-5.3 mark stock, I can't see 4.x being correct, but that is my opinion. Quote Link to comment Share on other sites More sharing options...
Slowsho Posted March 14, 2013 Report Share Posted March 14, 2013 I would have to agree with the comment above. Most likely have to add weight and a couple other things like slight down hill/uphill alot of different things can be factors. But 4.3 would be extremely fast for a stock sho. Myself with a tune is around the 4.5-4.6 mark(only tried twice so far) Quote Link to comment Share on other sites More sharing options...

Ok, so I've calibrated the app, and re-run it (it's about +15F warmer now than my first run, so about 55F instead of 40F), and these are the results which seem more in line with what you're saying: Conditions: 55F, 45% humidity, dry clear and calm, level pavement. 2gal, empty car with 250lb driver. 4,990' alt. Acceleration 0-10 MPH: 0.71 sec 0-20 MPH: 1.44 sec 0-30 MPH: 2.19 sec 0-40 MPH: 3.08 sec 0-50 MPH: 4.14 sec 0-60 MPH: 5.36 sec 0-70 MPH: 7.04 sec Elapsed Time 60': 2.31 sec@30.2 MPH 330': 5.96 sec@62.1 MPH 1/8 mi: 9.14 sec@71.6 MPH Miscellaneous Max Speed: 73.6 MPH Max Acceleration: 1.12 G's Peak Horsepower: 281 HP So calibration had the biggest difference; but tomorrow morning I'll try again when it's around 40F and see if there's much difference.

83racecrew Posted March 14, 2013 Report Share Posted March 14, 2013 That looks quite good actually, pretty accurate app, IMO. Quote Link to comment Share on other sites More sharing options...
JMR76 Posted March 15, 2013 Report Share Posted March 15, 2013 I tried the same app, stock and after LMS 93 tune. About 32 F both times. Not sure how accurate it was but it definitely gives you an idea. Even tried Ford Crown Interceptor for kicks. 2010 Interceptor 0-60 at 8.8 seconds. Anyway, results I got with the SHO are (whether accurate or not?) Launched at 2000 RPM. Stock: 0-60 5.06 60ft 2.04 1/8 8.50 at 85.4 mph 0-100 11.28 1/4 13.29 LMS Tune 0-60 4.29 60ft 1.89 1/8 8.02 at 88.1 0-100 10.31 1/4 12.48 Even if this isn't totally accurate, it still gives you a good idea of the difference in stock vs tune only.

Fa-SHO Posted March 15, 2013 Report Share Posted March 15, 2013 I'm going to try this tomorrow and calibrate to my known 1/8 time Quote Link to comment Share on other sites More sharing options...
bpd1151 Posted March 15, 2013 Report Share Posted March 15, 2013 I still think your #'s are on the generous side. I am running consistent 12.3's with 60ft's consistent at 1.80, and at 111-113MPH, with all the mod's I have right now, including methanol & cat less.... So umm yea..... but it does provide one with a relative range is suppose. Rather than relying on these various apps, and programs, and wondering how, or if they're calibrated etc. etc. , you're all (each) better off just taking 'em to the track and run'n the strip Sent from my DROID3 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Very cool! So the tune alone seems to shave almost .8 sec of your 0-60, and .8 off your 1/4. Seems to help the most toward the low end, as that's where most of your gains are. I like that, as for daily driving I'm rarely going to be over 75-85, but I do love the stoplight jackrabbit starts! Quote Link to comment Share on other sites More sharing options...

There is a review of an earlier version of the app on Car And Driver where they compared it to their high-end test equipment, and they found the app was typically reporting 0.3 seconds slower than actual speeds. I'd love to get to a real track, but for the moment apps are the best alternative I've got. Quote Link to comment Share on other sites More sharing options...
BIGFOOT Posted March 15, 2013 Report Share Posted March 15, 2013 i could see a 4.9, in great conditions but not 4.2-4.3. Quote Link to comment Share on other sites More sharing options...
steve142857 Posted March 15, 2013 Report Share Posted March 15, 2013 I would say your numbers are about 0.4-0.5 too optimistic, at least for the 1/4 mile... Quote Link to comment Share on other sites More sharing options...
