Re: Ported Intake for Sale
 

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:)

Do it!!!!! 12.42@117.5 on crappy street tires....probably faster if I had it tuned

Re: Ported Intake for Sale
 

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!!!

Re: Ported Intake for Sale
 

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

Huh, that's pretty sound thinking.

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.

Re: Ported Intake for Sale
 

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.

Haha now those are some awesome justification skills you've got there Lee.

Re: Ported Intake for Sale
 

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.
