Guess there's no guarantee's failures like this won't happen, however I continue to have issues with slapping turbo's and superchargers on engines that originally came without, without having had the internals of the engines upgraded. GM made obvious changes in the connecting rods, pistons, camshaft, intake valves etc. on the LT4 engine over the LT1 in order to avoid situations like this. I would hope such changes involving the internals are made by shops adding turbo's and superchargers to these LT1's. Otherwise, we're going to see allot more of these "Catastrophic Failures." Not to mention voided factory warranties. That's why I've chosen the 2015 Z06. No hassles, no worries..... Now which one has the higher price tag connected with it?So I did some digging, called in some favors, paid some folks off, and generally lied cheated and stole to get the following intel...
Word on the street is.... The car has less than 2000 miles of use since the HPE700 package was installed. The customer, who we will probably not hear much from due to some impending legal action, took the car out on the highway and made a pull in 3rd gear. He got all the way to the top of 3rd, then catastrophic failure. Story has it that a rod let go and the hot oil went everywhere. The car pulled to the side of the road, ignited, and burned.
There are still some details coming through, and I may have more information in the coming days, but am trying to get the best news that I can.
Not ALL of our builds, but "MANY" of our builds.Hennessey Warranty said:We offer our worry free warranty on many of our builds!

Yep! Never saw this coming...... Can't tell folks about this cause they don't listen. Not only that, but they'll actually argue about it and cop a major attitude. So how much is this guy going to have wrapped up in this HENNESSEY HPE700 by the time all is said and done? This is really tragic and for the life of me I can't imagine how a business can remain operating pulling what Hennessey pulled on the customer and more than likely many more we haven't heard anything about. NickJ Thank you very very much for bringing this to our attention. You've provided an extremely valuable service here and exposed a company that forum members should stay completely clear of. As long as people keep going back, or new customers keep coming in, Hennessey will continue doing business as usual..... Too bad a couple of major magazines haven't picked this up and exposed these practices to allot more enthusiasts.Digging deeper:
So this C7 was torched. The customer went back to Hennessey for a warranty claim. They supposedly provide a 1 year 12K mile bumper to bumper warranty... But if you go to their warranty page: Hennessey Warranty You will find the very cleverly worded:
Not ALL of our builds, but "MANY" of our builds.
Presumably, part of the reason why Hennessey is one of the higher priced outfits is because they can stand behind the warranty due to the fact that it is built into the price of the tunes and parts. They charge everyone a little more so that they can cover themselves if something happens. Story holds that the management at Hennessey told the customer to take it to GM to have the engine replaced and essentially refused to honor any sort of warranty. (Remember the "Many of our builds" line?!?
Obviously, GM took one look at the car, and laughed at this customer's request. So, now his GM warranty is very obviously voided, and Hennessey isn't interested in fixing it.
I think that this C7 owner is going to keep pretty quiet about this whole deal for a while as this could wind up in the court system.
Rumor has it that Hennessey has blown up 3 C7's in the last 6 months with Edelbrock and ECS kits.
