Hi everyone, though i should just joined this community since i own a 2007 RDX sh-awd Last month I used an iPhone 3GS to record 0-60 tries. this was like my 9th or 10th try. Tires were at about 44PSI hot on smooth level tarmac with stock Michelin tires. Oh and it was in S mode and used paddle shifters. weather was 7'c, 60% humidity, calm winds.

got 6.03s 0-60MPH:

• Max Speed 76.6 MPH
• Max Acceleration 0.62 Gs
• Peak Power 243 HP

• 60'2.42 @ 29.1 MPH
• 330'6.23 @ 59.4 MPH

• 0 - 10 MPH0.81s
• 0 - 20 MPH1.54s
• 0 - 30 MPH2.42s
• 0 - 40 MPH3.36s
• 0 - 50 MPH4.59s
• 0 - 60 MPH6.03s
• 0 - 70 MPH7.69s

for those who don't know, a good way to launch your car is to "torque launch". hold the brakes and throttle at about 2.5-3.5 RPM and let go of the brakes:

i wouldnt do that too many times...

MMike1981

...i also use dynolicious, but its kinda whatever for me, so much depends on how/where you have it placed, the calibration etc...its cool for 13 bucks, not half bad

pickler

well i've heard that before, but i thought brake-torque launch is the safest way for an auto accelerate quickly. on my 2003 TL i have been doing this every summer on the track and i even over-reved it couple times. The car still runs fine with no issues...

MMike1981

safest until the thing slams into gear, you are dealing with a consumer-oriented machine not a sports car that is designed around possible clutch abuse/dropping it into gear..it may be safe until you destroy the tranny, so between that and its subjection to much more heat buildup...you will eventually ruin the tranny if you are doing it alot

all im sayin is dont do it too much youll have a great time explaining that one, and paying for it

pickler

im not sure what you mean by that, the car in s mode can be chosen to be in gear before launch. For example i can even start the launch in 2nd gear if i want to. the car wouldn't change into gear two as soon as i let go of brakes, it will change to 2 whenever i hit the pedals and choose the gear. That's the whole point of a sequential gear box.

My days of doing 0-60 are over. LOL. But, with that said, the RDX really is a quick vehicle. Any small SUV weighing 4000 LBS with a four-banger doing 0-60 in the six second bracket is truly amazing!

MMike1981

when the power gets dumped onto the tranny all at once; thats what im referring to, im sorry for the confusion, as the tranny, technically would already be 'in gear'

I have Dynolicious now, but I am only getting 181-182 HP consistently. I will try again suing the suggestions above for brake stance, sport mode, etc., but this has me concerned, I have seen multiple posts with users getting upwards of 243.
Wat did you use for drive train loss and for the weight of the vehicle?
I have a 2008, stock.
Thanks!

pickler

hey sorry for the late reply i think i used 15% for drivetrain loss since its an AWD system and i still get 240+ whp. Also 4000lbs for the weight. I noticed the performance builds up the more i push the car and when the engine is real warm. so try 3-4 0-60 tests. it could also be you have dirty fuel injectors from bad fuel?

noodle4rdx

i totally agree!!!

Have fun. 6.03 seconds is pretty impressive!

But keep in mind the computer may be ratting on your brake-torque launch:

The transmission Power Control Module monitors the status of hundreds of trans parameters such as each solenoid and each clutch, but here are some of the pertinent ones:

Engine RPM

Accelerator pedal position

Brake pedal position

Throttle position

ATF temp

Wheel speed

When the PCM throws a Diagnostic Trouble Code for a trans abnormality, it takes a snapshot of all data input to the PCM as well as all fuel and emissions data. This snapshot is called the freeze data, and it would be recorded if a DTC is thrown during brake torquing.

During service the Acura tech first downloads and records all DTCs and freeze data. The next step is interesting from a warranty perspective, so I'll quote directly: "Drive the vehicle for several minutes under the same conditions as those indicated by the freeze data...."

This would be fun to watch if it wasn't your car, but you'll more likely see the Service Manager flipping to the "abuse" clause in the Warranty contract.

Additionally, a trans PCM DTC will not neccessarily light the CEL, as that is an emissions light. Trans abnormalities only cause the "D" in the gear selection display to blink. Might not notice that, but the DTC is recorded.

I hit just over 6 sec on that program whe nI had my RDX.

Carbon2008RDX

Agreed. And, who are you racing anyways? I'm not being sarcastic. Enjoy the RDX for the vehicle it is.

TLAcuraGuy

Yup. 6.03 seconds is pretty impressive.

lol no worries, this video is pretty old though and not the one of the dynolicious test which was taken just few months ago. car launches way faster now that the engine broke in. i haven't done a 0-60 test since this topic was started and i did have the car services recently and i was told the tranny and torque converter are in proper order. i hope so, it runs smooth and no problems so far. plus im getting great gas mileage and again i don't stress my car often.

ps: i noticed the car seems to get stronger/faster after you push it a couple times. not sure why but i think i also notice quicker downshifts and just feels healthier after a 0-60 test lol.
