Hi all, I am new to this forum and wanted to share my newest toy. I purchased 2020 Hellcat and sent it to Hennessey Performance outside Houston in Sealy TX where they increased the HP to 912. I am very impressed with this car and now know why you all love the Challengers. You can see more on my car below. Please don't ask me what I paid Hennessey as it was expensive but I have one of very few Hennessey Hellcats #4 to be exact. I could have gone to 1000HP but didn't want to pay the extra expense.

I also installed a Ravelco anti theft device which won't start the car unless this device is plugged in.

Nice. Its not the Hennessey of yesterday where they ripped one customer off to finish building another customers car. They have some good stuff coming out of their shop. But you also paid way more than having it done somewhere else. Which package do you have on your car? What fuel did the car make that power on?

They are the Premier Shop hands down

Ravelco wont stop a neutral pull. Another layer I guess. Nice car!

I was thinking the same exact thing.

I read all about that in the past, the experience I had was only positive form start to finish. I did take a tour of the facility and it was over flowing with cars & Ram Mammoth trucks. I did the HPE900 package.

Wow, I love it. Iwonder how many sets of tires I would go through every week LOL

Welcome! All HC are good HC here.

Welcome to Hellcat.org

Nice build, it's very similar to mine, but I have a Charger.

Are you going to the Track for some Fasst Fun?

Congrats,
Linda

Awesome power, it loses many races because of it, hard to hook.
The wonder whine of a hellcat.

I got the HPE900 and best fuel for where I live is 91 Octane.

Unless someone else owns the business, and he has made full restitution for all past theft, I wouldn't touch Hennessy with a ten foot pole. I don't care how wondrously he is doing now. A rattlesnake that has not bitten anyone this week is not something I'm going to throw in a kindergarten, the kindergarten in this case where I keep little Benjamin Franklin and his buddies.

I don't think John is a part of this company anymore. I think he's just a spokesman for it.

I read the package details and be very careful. You have a upper and lower pulley. That in itself is going to be too much for 91 octane unless they pulled all of the timing out. You could have saved yourself 20K by just doing a upper pulley (2.85) and making the same power as your car on 91.

On a side note, do the new Hellcats come with dual pumps in the tank or are they still singles?

How much does the Hennessey 900 HP package make at the wheels ?

Thanks, David

I’m guessing they tune it for optimal fuel. Probably in the 825 range I would suspect.

[Unavowed]

What does the Hennessey 900 HP package run at the track?

Thanks, David

FIFY.
In my 30+ years in the auto enthusiast hobby, I've never once seen a Hennessey built car at a track. But I do remember reading account after account of what he did to Viper and Corvette owners 20 years ago. A leopard cannot change its spots.

That's a lot more than I would expect. Livernois 900 HP package for 93 octane that I've got makes 750 rwhp.

Again I don’t know because the dyno sheet isn’t posted. It says upper and lower pulley and ported snout so who knows how much boost he’s running.

I had a Hennessey 550 Viper...after seeing what they did to make the 550 Viper...never again would I buy anything that said Hennessey on it
