New super car warranty

[black69]

I was talking to one of the dads in my son's boy scout group, that bought a new vette, and was having a super charger put on it, and said the speed shop doing it, could take it off, if something bad happened and it had to go back to chevy for warranty work. I said, I would not be so sure, the main computer could not tell something was different on that engine running the new setup. Sounded all really shakey/shady (and made me wonder, do non factory conversions operate this way?)

I told him this is why I like the Hellcat, it comes with a pretty good warranty. He said he felt he probably could get stuck eating the cost of blowing up the engine, if something went wrong and was ok with that. I disagreed with that mentality.

So what is pretty valid on this site to discuss, what are all the warranty views from Lingenfelter, Hennesy, Nickey, etc? Aren't most of these cars conversions with the original long block still in place and would be similar to the corvette conversion mentioned above? And what happens if you damage the differential or the trans with the added horsepower? Is that under warranty conversion as part of the conversion?

The closest factory car I remember that may have had probably had a decent factory warranty was a 605HP 2002 ZL1 Camaro the previous owner of my 69 Camaro had.

I had a Magnusun blower which was a TRD part on my 1999 Tacoma 3.4l. Full warranty, Toyota never had a probalem- probably because TRD offered it. FYI- he guy who ones the truck now still says it runs great and no issue with well over 150k on it.

Now there is something to be said for these motors such as the Hellcat which are engineered form new with the blower in mind. Many turbo motors have the oil squirters to cool the wrist pins- probably SC ones too and I'm sure a few performance N/A motors do, sodium filled exhaust valves tend to be reserved for forced induction, better cooling and a beefed up crank snout too. Many motors live a long life without these items, but there is peace-of-mind when engineered as new.

I'm not one to worry much about voiding warranty. I've always had success talking through differences in perspective and related failures.

I just searched for a comparable 700hp upgrade for a ZL1 camaro and found this:
2 yr/24K miles. I think its just covers the engine.

Then this one gives you 3 yr 36K miles

Or for 50 more HP, you have <span style="font-weight: bold">1 yr/12K miles </span>to try to have bragging rights on an unmodified hellcat:

Not sure how Chevy does it, but on the Fords, there are specific emissions-certified packages available through the catalog that maintain the factory warranty as long as they're installed by the dealer. You go to an outside shop, you're on your own, although many of those shops, at least the reputable ones, offer their own coverage in some form or another.

Emissions, there is another can of worms. Going though the 3 options I looked at, I would chose the Hennensy option, as it offers the 3 y 36K mile warranty. That is reasonable.

Hennesy and Lingenfelter are opening up the stock engines, and doing some porting work to net some of the horsepower gains. I feel, Nickey has to be pushing a lot of extra fuel, to make up for not opening up the engine, in their method to get the same 700HP. So if that's the case, I would be more worried with Nickey conversion passing emissions, when the tester gets in and revs the car up.

But, hands down, Hennessy seems to be the only logical choice due to the 3 yr warranty, and the odds are you have some margin on emissions compliance. 1 and 2 yr options, no way.

Speaking of Emission's, have you guys been paying attention to what's going on in California.....the noose is tightening again. [img]<<GRAEMLIN_URL>>/thumbsdown.gif[/img]

There was no factory warranty on any 600 hp 2002 ZL1. That car was built by GMMG and there are still angry people that ended up having to fix the engines themselves after the valve guides were shot after a few hundred miles due to lack of valvetrain geometry knowledge..
I would also take a Nickey over a Hennessy because he is a sponsor here and I have heard alot more great things about Nickey versus Hennessy.
Read this and tell me you would choose Hennessy.

And before you discount Nickey again because he does not open up some of his engines why don't you ask him before inferring his product is not done right.

Friend of mine has a 2015 Vette, Hennessy (Pre Z06), and I am not impressed at all. The New Z06's stock eat his lunch all the time.

He has more in the Hennessy than a new Z06.

This is from 2002, BTW. Is Hennessy still this bad after 13 years? I park at work near a newer Jeep Cherokee SRT with Hennessy emblems and I lust after it. Oh, and Csaba Csere is pronounced &quot;Chobba Chedda.&quot; Honest.

Charlie, referring to something 13 yrs back does not seem fair. I just checked, and maybe they are not as bad as you infer, as Jay Leno bought a 2011 Camaro from them. I think being able to convince Jay Leno is not an easy accomplishment.

Getting back to what I stated, the dominant reason I would select a conversion, it was based on warranty. Hennessy states they have a 3 yr/36K mile. The dodge 700HP competiton has a 5 yr/100K.

As far as Nickey, if I have to precheck on something that is common-sensical to me, before posting, maybe I should not post here anymore. I read those other specs, and if they (Lingenfelter and Hennessy) are doing something to improve breathing to get some of the horsepower gain, then the balance has to be increased fuel delivery. All of them seem to be polishing the intake flow. I looked at some of the injector specs, and I see 65 lbs for Lingenfelter and I see a 85? for Nickey. So I made the comment, when someone else stated emissions, the Nickey conversion has to likely be pushing more fuel considering they have not touched the heads. I further stated nobody would NOT pass emissions, only pointed to concern. After 2-3 yrs you would be on your own, and some of these cars wont go in to emissions testing until after the warranty expires. Here in the state of Illinois, I believe its 5 yrs from new, and then every 2 yrs.
