Hey guys, here is another video of me and my Aurora doing a 0-110mph run. The last video I posted when I did a 0-90mph run was so dark that I figured I would redo it. So, I want to know your thoughts on this, do you think I have approached the speed of the Seville STS, or not really?
This was done in drive, no power braking and I use 87 octane

0-60 in 7 seconds, 0-100 in 18 seconds & 0-110 in 23 seconds on, as you say, 87 octane.
Do the run again, on 93 octane. There will be an improvement. You should be able to get into the 6 sec. range (0-60) on 93.

Using stop watch on videos 4-5 times
......... 0-60, 0-80, 0-90, 0-100
Your's: 7.3, 11.6, 15.2 19.2
STS: 6.5, 10.2, 13.2, 17.3
Mine: 6.3, 10.2, 13.3, 17.4
Started yours when tires chirped.
I timed about 4 different STS videos and one is definitely going down hill or something. So that is about where the 3 landed.

Yeah you should definitely be in the 6 second range... my classic was in the 6 second range lol.

Geez, my car is slow lolol. I thought for sure it felt fast and would have thought id have been much closer to.a seville than I thought.
Yea maybe ill try and pump some 93 octane in her. Maybe I needa tune just like you shelby. My mods probably messed up my air/ fuel settings

No, it's really not, it honestly looks closer to the 3.5 range IMO lol. It feels fast, but hey.
I don't think he has a tune either.

My 2001 4.0, running on 93 & with the TC off, will spin the tires very nicely at less than half throttle. I never used 87 because I knew that it would be down on power running 87.

You can see how much the Aurora really shines in that 50-80 range. The passing power was a priority when these cars were manufactured, and it really shows.
I find that pretty quick! A 0-60 is almost always decided by the launch. If you went back and timed the STS from 60-100, I think you would find the Aurora closer than you think.

I agree, and I brake stall mine for launch. ;D So 60-90 an effective measure of power Your's- 7.9 STS--- 6.7 Mine-- 7.0 The STS has a pretty good rpm advantage on me. (for having same cams) Plus the ones I saw all had performance exhaust. Since we have stock to go buy (thanks Marc) 50-70 Stock--3.9 Your's-3.4 STS----3.2-3.1 Mine--3.1 (guessing that's because from 50-70 it doesn't get the chance to hit the higher rpm band than me) It takes forever to do this, but I can't help it I'm just as curious as you ;D Plus I really like pushing numbers and figuring stuff out. I found a couple STS videos that I was actually faster than and used 2 of the quicker ones to compare, so maybe those STS numbers are a little quicker than a true stock one  |

Shelbyracing.....OK!
I also wanted to add that I once timed a 1970 Chrysler New Yorker
with the 375 HP 440 CID from 50 - 70 in 4.5 seconds. And the 2G did that same run in 3.9 seconds as quoted in my above post. This shows how efficient the 4.0L is.

Wow Marc, why is your car so much faster than stock? I didn't know you were modified...
You ever take a 1/4mile run with your car....from the section on the forum, I gathered the avg. 1/4 mile time seems to be 15.7-15.8. I only saw guys in the 14's, but they used Nitrous. What is the current fastest "4.0" Aurora without Nitrous in the 1/4 mile?

I think you misread his post Scotty. 50-70 in 3.9 That's pretty sweet however.

ScottyAuroraV8......I have never run mine. I may do it someday, even though I'm coming up on 70 this year. BTW, I have never done any performance mods.
The fastest Aurora at ACNA in the 1/4 seems be Aurora40's 2002 4.0. This car turned a 14.868 @ at somewhere between 92 & 93 mph, IIRC. The only mod that he made was putting in a Corsa exhaust. He also took out a small amount of weight, the back seat, the spare & the jack. He didn't use nitrous.
If you want to ask him about this, e mail him. He hasn't been here in several months.

Damn a 14.8 and only with Corsa. I never took my car to the track yet, but I have Corsa exhaust and i def. feel a difference, but I dont feel a difference that would put me into the 14's LOL. So him taking out the back seats, spare etc...lets say he saved 200lbs, thats 2/10th off his E.T. He must have a factory freak. Lucky Lucky Lucky! I have a Corsa exhaust and my own air intake setup I made. I could only wish it puts me into the 14's. I need to get some good tires and some money together and go one day, It be nice to find out where I am. But I will make sure to put in 93 Octane. I just hope gas prices dont go up too much more  |

I don't see a y - pipe making a 50 hp difference though. That is a full blown STS track time man. They run 14.8-15.2 300 HP. Same trans & 70 lbs lighter. Here is a Corsa STS youtu.be/IQ-N7fMfgNg |

I was not suggesting a y pipe smoothie would make a 50 hp difference, I was simply stating that it's a good idea to clean them up.

I know that, I was just saying there has to be some other mods if he ran 14.anything . Or maybe he unhooked the serpentine (10-15hp) though might hinder computer or ignition performance

For some reason it always seems that the 2gs are a pretty good deal faster (like a half a second in the 1/4 mile) and the 4.0 2gs are only like 70 lbs lighter than the classic and do have stock autobahn gear, even autobahn classics don't seem to run as good, I y think maybe when they did the 2000+ northstar redesign maybe the new 4.0L northstar had an underrated horsepower.

Are these capable of hitting the 140mph mark?

I think maybe when they did the 2000+ northstar redesign maybe the new 4.0L northstar had an underrated horsepower. Agreed 100%. I have been driving a 2001 4.0 for more than 12 years. I gave it a careful break in & have always used 93 & 94 when it was available. Past about 80 mph it feels almost as good as my prior car, a 1972 455 442 W-25. And I did some work on that 442......advanced timing, richened carb & turbo mufflers. My Aurora is showroom stock underneath the hood. Not even as much as a K&N. |

Are these capable of hitting the 140mph mark? Some time ago, I found a video on Youtube of a Classic doing a claimed 140 mph. So I think that a 2G could certainly do that with the speed limit taken off. www.youtube.com/watch?v=wtOyzTCSb80&feature=context-cha(Paste that into your browser. The link won't work.) |

Being that mine is a 2002, I wouldn't feel comfortable pushing an eleven year old car that hard. And mines a v6. Really struggled at 130.

Or maybe he unhooked the serpentine (10-15hp) though might hinder computer or ignition performance Figured you did, lol. I wonder if there are controllable tensioners? It would be nice to hit a button and be able to let your belt slip when you want it to, that could make a big difference on a 1/4 mile. I have been up to 137 in my old Autobahn Aurora. |

the car in the video above isnot pushing it out all the way. A Northstar at full wrap will shift out of secondinto third near 90 mph

Somebody here once mentioned that they had taken their 2001 3.5 to around 135 mph. I just can't remember who it was.
