Just went to the track yesterday, and ran a 14.20 @ 100.15mph, 2.38 60'. Car is a 2010 M5 SS, with LSD and Brembos, at full weight with 3/4 tank of gas. Only upgrades are the GMTU and BFGoodrich KDW2 front tires (245/40/18) dropped to 28psi

Nice run wish our tracks where open up here

 

I could only find the video below in my signature, of me running low 13's on street tires, from 2 years ago.
Spinning the tires on every single run, with street tires. I believe 13.08 was my best ET that day.
MPH was all over the place, because of no traction, with street tires.
I just ran across this video a few weeks ago, while searching another HHR SS video.
The only reason that guy filmed, & posted this on YouTube, is because he saw me run 110+ mph the run before, he just found it so unbeliveable, that an automatic HHR SS could go over 110MPH, & 13.0's, on street tires.

You guys are funny, you should really be questioning 110+ mph, as that's harder to do, with an HHR SS automatic, then going into the 12's.
If you understand how hard it is to go over 110mph in a HHR auto, you will than understand the power that I'm making.

MoonShine, if you have been around racing a long time , than you should understand what a boosted launch is. A boosted launch with a Turbo automatic is so so sweet. Ask anyone with a Turbo Buick about a boosted launch, & watch the smile on their face. Has anyone here ever even seen a Turbo Buick at the track taking off from the line with a boosted launch, it's such a sweet thing.
I can hold 10psi @ 2,800rpm at the line, with drag radials, resulting in sub 2 second 60' times.
Also guys, listen to the other automatic HHR SS on this forum, & in this thread, tell about laying down 2 strips of rubber, or look at my burnout in the video below. I can really 'cook' them..., yes, both of them.

Also I don't think alot of you understand the power that can be made in an LNF with a 50/50 mix of E85/gas.
I'm getting 30-40hp increase from E47.5 alone, with only the mods in my Sig
You will see some other HHR SS in the 12's this year, Joe Schulte, for sure, as he has a good plan.
You stick shift guys don't have it this easy, without a preloaded drivetrain, with a boosted launch

So a video, showing low 13's, + a timeslip, showing 110mph, from 2 years ago on 10/23/10, & a timeslip from a year
later, with a better 'tune', & drag radials, showing sub 2 second 60' & 12.86 ET.
Why the disbelief, with an HHR SS automatic doing this ???

Here's a 110mph timeslip from the day, 10/23/2010, that video in my signature was shot.
The YouTube video shows it was posted the same day, 10/23/2010, also
Also another time slip one year later on drag radials, 87+mph at half track, is awesome too.

 

I am not trying to start anything but your vid saying you trap a 104 mph at 13.1. You have 2 diffent sets wheels on the front so were running drag radials? Just saying a video speak a 1000 words and anyone can post a timeslip. A video would really help you out next time you go bring a camera or a phone have someone get on tape. Then show us we were wrong!

 

Show you that I was wrong about what.
The Video shows a low 13 second ET from 2 years ago on street tires.
A timeslip that same day dated 10/23/2010 like the videos date, shows 110+ MPH. If you read the comment from the video poster, he states that he saw
one of my 110+mph passes the run before.

A time slip a full year later shows my best ET of 12.86.


Ya, that day 10/23/2010, the MPH, & ET were all over the place, because of wheel spin.

Yes, 2 different wheels/tires that day.
I was trying out different tires, pressures, to try & get some traction.
The wheels that you see on the back are from my 2004 Malibu Maxx,
16x6.5 ,with Firestone Indy 500 tires.
The wheels on the front are from the TireRack, 16x7 , with wornout, almost bald Firestone Blizzaks winter tires.
I was trying my best that day to get into the 12's
13.08 best ET, & 110+ best MPH, that day.
I just couldn't 'hook' up at all on street tires.

 

Just saying a vid of 12 second pass would be great but until then...

 

So
Correct me If I am wrong but the fastest time posted at a track by an HHR SS still was done by 2005HHRauto?

 

After two trips to the track flogging the stock tires I bought a set of 235x60x15 M/T drag radials & a pair of aftermarket wheels, I tried launching at 2000,3000 & 4700 & each time when the tires hooked up it pulled the RPM down, like a carbed motor with to small squirter, the only mods i have are catless dp, fresh air intake & 3"split side exhaust, I think after I add a tune I'll be able to drive thru the hard bite of he drag radials, best mph 99.43, best time 14.55.

 

someday Hubby says he wants a set of M/T's as well......

 

I posted this elsewhere, but I guess I shold have put it here.

these are first and last runs. the first one had the .780 reaction...UGH!
the last was fastest, first best eta. can't wait to go back this weekend. my buddy Jason is bringing his 'balt.
