I put down 391rwhp on my 92 with an off the shelf Rippie chip...no specific tune, porting and headers. Thats 450-460hp...so I would think 450-470hp possible with a good motor and tune......(ported, headers, etc)
At this point its every ZR-1 owners moral obligation to stay ahead of the C7 ![]()

Porting, injector's, coils, wires, gaskets, chip update ect. Sounds like more than I should be spending right now. Plus paying someone to do it. (I'm a terrible mechanic). Much as I'd like to get to 500 hp!!!

Use my wifes logic:
New C7 465hp; your cost $60,000 Ported intake for 460-470hp: $900 If you buy this, you will save yourself $59,100...hurry up before you blow $59K

Steve,
Top end w headers will get you to within a hair of 400rwhp. I'm pretty sure there's a dyno here w my motor doing 399rwhp before heads and cams. And yes tunes are available. |

Stock chips tend to run slightly rich as a safety precaution - the factory didn't tune each car individually, they threw a safe, one size fits all tune on them. Usually a stock chip has enough extra fuel for a mod or two, once you combine a few mods... say headers, exhaust and a ported intake then it's time for a custom prom with more fuel. This is a very common grouping of mods that gets most Z's to approx 400rwhp and Marc and others have chips ready made for this combo.

Using that logic I will save roughly 50K dollars doing the Big Cube engine over buying the fully loaded C7.
Let me see if I can get that past my wife. Maybe if we go to a Chevrolet dealer look at an order sheet I can say something like I can't justify 72K dollars for a car with 450HP when I can have my current cars engine redone for around 20 and have around 700 HP. Lee, That sounds like perfect logic to me. |
