LT4 performance estimates.
What do you think an LT4 powered Z Car will run? Just to compare A stock A8 Z06 has Ran a 10.4

Depending on the stock street tires..estimated 4,000lbs curb (3,750 + 250 in engine, brakes, etc)..
With the A8 on street tires..11.6x-11.7x @ 120mph On DR's..11.3x-11.4x @ 122mph On full slicks and skinnies..10.8x @ 124 mph. Assuming good prep. Last edited by SpeedIsLife; 10-28-2015 at 09:44 PM. |

I'm thinking it will be around 3950 lbs and run about a 11.7 at 125. That's my guess

I'm guessing 645 hp/tq at 3985 lbs.
0-60 in 3.7 1/4 mile in 11.6 at 124

Hero run of ~10.9 stock on stock tires is about right if its ~4000 lbs.
zo6 hero run is 10.4 I believe at ~3500lbs. Lot of other variables...but should be about .5 tenths slower looking at just hp and weight. Should be too close to call with a hellcat. Give the edge to the cat on a DR and the edge to the lt4 zl1 on stock tires. Just my guesses... |

I recently saw a hellcat on the showroom...looked awesome. I hope the new ZL1 lives up to its performance and looks when compared to the hellcat. I also recently drove a non scat pak challenger, and was not impressed with the driving...it was a boat!

I'm fully expecting a 10.9 stock run in the right conditions with the A8. Tires/lower Pully/tune/intake and you have a low 10 second car. Pretty nasty. I'm really hoping that offer a "track package" with some weight loss and carbon brakes.

Waiting for next year to decide on the ZL1 or Hellcat or anniversary SS.

I just pray it's worthy of the ZL1 name, i.e. bulletproof. The LT4 so far has proven rather fragile (in conjunction with the auto trans).

I wonder, what percentage of deployed LT4 engines have had issues.
