Getting ready to purchase a C7 . Was going to buy the Hellcat but just didnt like the looks of it.

Thinking about sending the c7 to Hennessey performance in houston Texas for one of their performance packs.

Anyone else had the Hennessey upgrades done. If so how does the car run. Thanks Brad

I haven't YET, I been looking really hard. What package are you thinking about?

bradley21ss

Hpe600 or 650

3 Z06ZR1

One for sale in the for sale ads! #1 if I remember!

not to be a wet blanket here but you need to research their track record and warrenty threshhold before you make that choice

Try Lingenfelter Performance Engeering or Callaway, both do great work and many will tell you that they are satisfied.
Callaway Chris is on the forum a lot. Lot for some of his posts.

Research is your friend, sir!

Callaway if you want to keep the warranty.

Hennessy is a known crook, he will sell parts off your car, then your car will sit until the next customer comes along. Basically it's a Ponzi scheme for car guys.

Its just hard to believe a company like Hennesey could be so terrible. Thanks guys for letting me know. Im glad I found the Corvette Forum. Looks like it will be LPE, if I decide to mod it. Thanks again!

Uh oh.

WOW

I think that's also what they said about Bernie Madoff.

Vetteman Jack

They are two very reputable companies.

does adding a supercharger of any brand (other than Callaway) completely
void the factory powertrain warranty ?

Maybe you should consider polling the Callaway owners on this forum for their experiences/opinions prior to making any decision
