I'll try to hit 180 this time, Joe.
Better late than never.
579 rwhp /510 rwtq
Stock was 527 rwhp /494 rwtq
Hmmm....well, I was expecting to run in the low 180's at the Texas Mile this month but now it's looking like breaking 180 is going to be a challenge. I'm at the same power level as you. I'll be running shorter stickier tires than stock and my car is lowered about 1.25" with Motons. The shorter tires might help a bit with the gearing.
Did you shift easy or were you banging the gears? What rpm did you shift at?

Correction 579/546 not 579/510.

I think 180+ is definitely possible. Rolled out in first,6300rpms,firm shifts. Crossed the end at 5750 rpms. Had a 12-15 knot crosswind so about a 7-9 knot headwind down the runway. For the mile up to 600 rwhp looks like 3:73's would be best. With more power than that you probably would run out of gear.

Awesome. I was number 81 at the Texas Mile back in Oct 07.

Great run Keith! Is that a record for a N/A Viper?
Do you think a 5th gear mod will allow you to hit 190 mph?
Cheers,
George

Thanks! Don't know about a record. I do believe that the 5th gear mod would put 190 in reach.

You really got to give the Gen IV credit, what other car can win a Car Craft shootout, run 10.7 in the quarter mile, do 185 mph mile runs and run around in stop and go driving with the A/C on?
Most cars that show up to the drags and run 10's are on trailers, run race gas and can barely idle....imagine when someone gets into the computer of these monsters. I bet there is another 40 to 50 hp to be had with tuning, race gas and playing with the camshaft timing. Who will be the first to crack the codes??

Check out the lift on the front end. Air running under the car would hurt top end speed but the rear wing is probably the biggest issue. Great for corners, but...

Holy Sh%t!!...that is an awesome speed. Ok, so does this mean that with a lower 5th gear 200 mph is within your grasp?
This has to be some sort of record, right? Any other Viper with a stock block and displacement even get close to this?
Were there any ZR1's running the mile and what kind of speeds did they hit?
Again, congrats on the awesome accomplishment.

Thanks George!
There was one ZR1 for sure, possibly two. I don't know what they ran.
I think low 190's with the 2010 5th gear. No way 200.

J&R3xV10, You did 190 on a public freeway?????

The engine may be providing more torque, but at a lower rate, effectively reducing the torque at the rear wheels. Through gearing, at a given speed, torque times times rate determines how fast you accelerate. Torque times rate is power, so you want to be in the gear allowing you to create the most power from the engine, not torque.

I guess this is the reporting thread to document mods/mph.
TX Mile, March 2010
Best run 180.8 mph
Mods: 2006 coupe with stock engine, stock exhaust manifolds and catalytics. Paxton kit with stock kit pulley, and Magnaflow 3" mufflers.
Also, there was one 100% stock ZR1 there on Saturday (black one). It went 180.1 mph best. At the last event, the quickest stock ZR1 went 185.

Well crap, I didn't know that was you. I watched you make that run.

LOL! Nice pic of the MPH sign. I checked your car out on Sat, nobody was around. Late afternoon. What offset are those SSR wheels?

Does the IV ACR have adjustable coilovers?
If so, drop it as low to the ground as possible once you get there, might kill more of the air resistance & front lift.

Saturday afternoon was the one time I walked to the staging lanes. LOL
Not sure what the offsets are but I can tell you the backspacing is:
7 13/16" front
9 7/16" rear
Measured to the outer edge of the lip.
Fronts are 12" wide edge to edge and rears are 14" wide edge to edge. You should be able to calculate offset from those dimensions.
Who needs a 5th gear mod to hit 190? Apparently not a GEN4 Viper!

It's crazy what a mildy moded Gen IV can do! 190mph in the standing mile is no joke. I can't wait until they figure out the computer and start upgrading the cam and heads.

My last time out I ran 175mph which was a 3 mile improvement over my last outing. My 09 is 100% stock. Keith your 190mph run is incredible with only minor mods. Great driving.
Please allow me to tip my hat to you sir
I have had my disease(Need4Speed)in check for over a year now. Posts like Keiths will force me call DLM for more power. The pressure oh the pressure.

I ran 167 at the Tx Mile back in Oct 97 with my 96 GTS. Car has Borla exhaust an a K&N FIPK unit. It was really hot that day and the headwind was between 10 - 15mph.
