Hennesey 2009 CTS-V...11.45 @124
that's one of the reasons I choose to not hang on to the ZR1. The car was a monster stock and now it is a real monster, just so fragile. I did just purchase a new Chevy Avalanche last week, we will see how that treats me before I commit to any more GM products. I must also admit the new Camaro has caught my eye and have thought about buying one of those and gutting it and turning it into a street legal 1/4 mile monster. I can't get too ahead of myself though, I am modding the hell out of the Avalanche and hopfully the new SL will be here in the next few weeks, those two projects should keep me busy enough.I for one, am glad you continue to push the envelope and share your good and bad experiences. Keep up the good work.

Definately low 10 sec potential, possibly 9's perhaps who knows. But the fact the car is so new and running these times, tells me its going to be a beast in its own right.
Never mind all the hyperboil about cheap GM stuff, I agreee to a certain extent, but go take one for a real flogging.
As for the Hennesey run it was on 20" PS2's.

Hey bud how ya been?
thought it would be faster...think it has pulley, long tube headers, tune, upgrade HE, midpipes, high-flow cats, Cold air induction. An E55 with same stuff is just as fast. Maybe the Cadi is all hype


the cars like mine have DRs, throttle body and cams...so definitely not an apples to apples comparison. I am impressed with this timeslip. How long did it take the 55 motors to run 11.45 - 2 years at least? I bet this things will be in the 10s years before the 55amg motors are. We are now 6 years out and not one 55amg has gotten into the 10s without the juice. I am sure this will change in 2009 but still...give this car props.
The only car that comes close for similar mods is DJE's / Derek's car which had DRs and pulled an 11.38@123 or so with a low 1.6x short time.
If this dude slaps on DRs his 1.95 short time can drop to 1.7 and his 11.45 will drop to a 11.1-11.2@125. And he doesn't have cams, throttle body mod and weights 200 more...pretty darn impressive if you ask me.

I believe his 60' was a 1.77, the 1.95 was his reaction time according to the slip they show on the video. 1.77 is respectable, as I already stated, traction was the big issue with the old V. If that 1.77 was on street tires I am very very impressed. That looked like a pretty clean launch, not sure if that was a hop or just a chip about 50 feet out. The best I can muster with my Lingenfelter on street tires is a 2.06 60', it either smokes the tires, or on the rare occasion it would hook, it hops all over the place and sounds like I am going to drop the rear axle on the track. I'm sure there is plenty more to come with this platform of the V, should be an easy 10 second car.

Your CTS-V is on its 7th read end...IIRC, you said the factory replaced it five times which begs the question why the tuner you used also had at least one failed upgraded rear end? Again, if I am reading your posts correctly.

I need more power!
If Wayne has another track day, let me know in case I miss the posting.

I'm still thinking of selling the 'vette and gettting an SL55 or E63 (wagon would be cool). I'm afraid I'll miss the torque of my turbos though. I keep checking autotrader/Ebay all the time. Prices are getting better.

Baller---they dont even need a year!!
They ALREADY have a better IC (from the ZR1).....
I was reading that the STOCK....I SAID STOCK ZR1 throttle boddy is 76mm!!!! In short order (1-2 months) Accufab will come out with a 160mm single blade TB for them like the cobra's have......Just those 2 mods will be worth 60-70whp and 6mph!!
Put money on it----Pulley/Headers/Tune/IC/TB---will trap 130+mph THIS SUMMER.
Did we mention that the whole lot of mods i mentioned will cost $4,000-5000 tops!!
+10000000 for these cars being a used car bargain!!

I think the ebay ad answers the issues with drag radials. They were running the new Nitto 20" drag radials. Those drag radials are super tall 275/40R20 (28.82) or 305/35R20 (28.58). It was no wonder the sidewalls looked large. I am sure an 18" drag radial would have performed much better.
