700 & 800 HP Upgrades, Any Takers?


Recommended Posts

It's interesting they are not upgrading the transmission for the 700-hp variant. Didn't think the stock 10-speed could handle that much power. Maybe the 3-year warranty puts any concerns at ease. 

 

I'm a simple man. I want just the power without the exterior upgrades.

I wouldn’t go through Hennessy for it. They seem to cater to the “more money than brains crowd“. Not only is that package $24,000, but that company has screwed a lot of people over...plenty of credible horror stories online dealing with them. ?

Oh man, didn't know that. I thought Hennessy was a reputable brand.

I get that every business has to deal with a bad review every now and again but there seems to be a lot of them as it pertains to Hennessey. And some are pretty shocking in their disregard for client’s vehicles...especially at the price point they work in.

Wow, very shocking and quite unbelievable. If all this is true, i wonder why they are still around. Surely all the litigation must have sunk them somehow. Now I'm really scratching my head why GM dealers are directly offering it. Surely them must have done their homework.

Yeah, you would think. I guess I’d feel more comfortable with ordering it from a dealer rather than dropping off a truck I already bought to get done up there. But neither really interests me...there’s better tuning shops that are actually in my area if I really want to add a blower.

Yup. Remember hearing about them working on a customers viper. The customer wanted the oem parts but they sold the parts and pocketed the money.

The 10 speed is the same as the one in ZL1, should be able to handle it no problem

The 10spd the trucks use is not the same as the ZL1, the trucks and the Camaro use a different variant of the 10L90E that the ZL1 uses. The truck/Camaro version is the 10L80E. It is built slightly different, partially in how the internal clutch packs work and the torque rating.

Thats the info I caught from reading up on the two versions of the A10.

I’ve done blowers, radically tuned diesels etc. My purpose was fun acceleration some times on daily drivers. Some I did my self others for lack of time locally through a trusted shop. The money I saved more than paid for warranty problems if they came up. Never did. As far as the other goodies these builders do for the money. For daily drivers it’s over kill to the max. When I was going to do road or drag racing I bought a vehicle for that. Also with the money I’d saved.
