Bet this 850 kit runs about 20k. Wouldn't buy anything this joker sells.

I think it's actually 26k

Wow 131 mph. What a joke. Mine went 128 with a Cai. If it were making 850 it would run at least 140.

STUNNAH · 05-19-2017, 01:51 AM

wow...Totally unimpressed...

unavailablezl1 · 05-19-2017, 07:14 AM

Not worth that amount of money. To go how much faster. Really?

IneedAZ · 05-19-2017, 08:10 AM

Too much work and expense for the small gain. Too slow for the 850 IMO. Hate to bring up the HC, but more weight and less power running close to that et with just DR.

It was hot and humid when we ran it. It will go 10.3 @ 135 mph in cooler air. Car makes 706 rwhp on 93 octane pump gas through the A10 auto. A stock ZL1 A10 ran 122 mph on the same day and same conditions.

And you just pulled this from someplace the sun doesn't shine? A car can be said to go a certain speed/ET when it does so. Formulas and chemistry calculations are inapplicable.

Considering a bone stock A8 Z06 runs 10.8s on stock rubber and has gone as low as 10.47 on stock rubber, this is extremely unimpressive for 700+ RWHP automatic car that has only a 300 pound weight handicap. I'd hope for at least 10.2s or less. Guy with a last gen ZL1 coupe auto does 10.2s back to back at 703 rwhp on 20" wheels, plus gen 5s are about 100-200 pounds heavier that G6 ZL1.

We'll see when Vengeance or Fasterproms comes out and puts down 9s at similar power levels as this.

Lets see spend 27k on modifications and labor above the cost of the brand new vehicle. Loose your vehicle warranty as well as any resale value only to run 2-tenths better than a stock A8 Hellcat with DRs. Sounds like a good deal to me

I get it, some of you don't like Hennessey...but come on guys. No need to flame. If you don't like him or if you think the price is too high or if you think the car is too slow for the upgrades then don't buy it. But you don't always have to trash him. Just chill out a bit guys.

Hennessey Performance · 05-19-2017, 12:23 PM

This package costs $19,950 with a 2 year warranty and we build 1-2 per week.

I am not bashing as much as disappointed for that power level. Why is it taking 200 hp to drop 1/2 second. Now he mentioned 10.3 in better weather...that definitely sounds more appealing at that power level. I thought we would be seeing mid 10's at the 750 power level with these cars based off our heavier competitor. I appreciate any company willing to test and make the car faster.

The best we ran on the stock car with drag radials was 11.27 @ 123. Other shops have run similar times. Thus, the gain is 8 tenths and 10 mph. DA (weather) has a big impact on LT4 performance. The small blower makes good power but can be effected by higher ambient air temps. The cars will fly with modifications in colder air. Or you can add nitrous or meth for cooling. Also, the stock ZL1 A10 made an impressive 588 rwhp on our dynojet dyno which indicates more than 650 hp at the motor. Our gain was 118 rwhp.
