Hennessey - Callaway - Yenko
 

Who has the better platform for a 2021-2022 ZL1?
Are their any others?
Go!

Hennessey did a nice job with my Stage I. I've never owned a Callaway or Yenko. Katech is also a top ZL1 shop as is LPE.

Stage 1 was that HPE750?

850

Do you have any 0 to 60 and quarter numbers? And pics of the mods

No times, still waiting on rear wheels/DRs. Here's a video of the car at Chapman Auto Performance, that did my Stage 2 work. Hennessey did Stage 1.


I'll take another video that shows more of the details.

I currently have one of the Hendrick/Callaway for Hertz cars and am selling it(Prefer Corvette platform). I have had experience with Callaway, LPE, and Hennessey by personally owning all. I haven't owned a Hennessey in anything other than a Viper though. The Yenko's I only know through second hand experiences I have driven a couple though.

1. Raw power/performance - LPE. Their packages make the most power if you have other cars this may be the way to go.
2. Complete Package/Support - Callaway. By far if you are looking for more power and absolute reliability this is the way to go! They have a dealer network, any place in the nation you can get your car worked on etc. It may not be as much power but for a complete package they are the way.
3. Scammer - Hennessey. There is no way that this company should be trusted in any way. They screwed a TON of Viper owners back in the day.

If this were a purpose built car for racing that I could have down for months at a time it would be LPE, otherwise I am going to have a Callaway setup.

I'm very pleased with HPE's work. I have no knowledge or interest in what they are rumored to have done wrong in the past. I've heard stories about every shop in America.

Hennessey - Callaway - Yenko, I feel like a song from hiphop group tagteam coming on.

French vanilla, rocky road, chocolate chip, cookie dough...

I have heard nothing but bad things about Hennessey. Maybe only on a personal level and not product but that would rule it out for me. I personally would say Hendrick Motorsports. But I am biased living in Race City :)

I'm still trying to figure out how this has anything to do with the possibility of a GEN 6 Z/28.

Because, hot ham water

Then you haven't read any of my dozen or so posts here saying I'm pleased with them. You don't get to their lofty position (probably #1) on the performance shop food chain without producing excellent products.

When dropping $23,000 I want to be singing the Number 1 selling song available. But I see no listing for Hendricks Performace Opertunities, perhaps you can lead me ing that direction?

I meant no offense. You hear a lot from people, especially when it is negative. People usually do not go out of there way to vent positives.
