My new Z06 is at my house

[JulesMaximus]

I do around 7k a year on my toy cars.

That's probably close to how many miles I put on my last bike the first year.

Might have to revisit this thread in a year and see where we're at.

so nice congrats man! Great color and options man

 

[Railgun]

Just for you. A badge!

That's the part I'd be seeing most. :whiste:

 

[boomhower]

Awesome ride! I love the aero bits on it.

After 350 miles, the wheels are still shiny silver! MMMMM no brake dust.

I did have to rinse off the dirt today. It got driven a lot in the wet Friday and Saturday. The cup tires handled a wet road better than I expected. I won't drive in any standing water though. That would not work.

Must be nice to have CCB's. Just got done washing my car and had black dust just pouring down the driveway.

I put 9,500 miles on the '07 C6 I had before I sold it in June of this year. Received 67% of what I originally bought it for in June of '07. Not bad for a 7 year old car. Averaged 1,350 miles per year. I'd like to get a C7. Just don't have the same desire for cars as I once did. That may change.

 

[Ferzerp]

I had about 6100 miles on the C7 in a year.

I buy them to drive them.

Ferzerp, have you seen this?

Headers/exhaust, blower cam, port heads w/ supporting valvetrain, smaller pulley, CAI, followed by a tune. Easy stuff to do. Looks like there is a lot that can be eeked out of it. I'd have fun doing all that and seeing what can be gained.

 

[Ferzerp]

Yeah, I've seen that. It is interesting to me that the HP is flat from about 5200 to redline stock. I don't place much if any faith in the actual numbers that dynos spit out, but usually the torque and HP curves are at least somewhat accurate. I wonder why they tuned it that way.

That's exactly how the LSA was in my CTS-V. It's the combination of the S/C and OHV not being able to force enough air into the engine. Don't know if that's common across other engines, but pretty typical of what LS engine dynos look like.

The LT4 in the Z06 runs at a relatively high 10.0:1 compression ratio for a FI engine. In comparison, the LS9 in the ZR1 has a 9.1:1 compression ratio. Using aftermarket heads, or simply thicker head gaskets on the stock heads will increase the chamber volume and reduce the ratio. The gains from a smaller SC pulley would be greater.

The vengeance folks have stated that the stock pulley is already rather small, so physically there isn't much room to change it. In their testing they only went marginally smaller. I guess you could overdrive the belt if you really wanted to.

I'm not big on adding more power than it already has though. I tend to leave my stuff stock, and then upgrade before the warranty runs out, only having cars under warranty.

 

[AdamK47]

I just read that the SC on the LT4 is 1.7L and not 1.9L or 2.3L, so it's probably not worth messing with the compression ratio. I'm sure we'll see some owners upgrading to a larger unit though.

 

[Ferzerp]

It's a 1.7L already spinning over 20,000 rpm peak

 

[AdamK47]

That's pretty well maxed out stock then.

It's got some room

CAI, tune, slightly smaller pulley 660whp/663tq

Stock it put down 585whp/617tq

EDIT: someone already posted it

 

[AdamK47]

I was referring to the SC being nearly maxed. There's plenty of other things that can be done to the engine though.

 

[Elganja]

the upper pulley is the easy one to change... wait until someone comes out with a larger lower pulley for the crank (similar how they did w/ the terminator series of mustangs)

then they will really be able to push the stock blower

 

[AdamK47]

There are good reasons for the small blower. Lighter, spins faster, higher compression for DI, and better response.

Vengeance is already looking into a lower pulley/balancer upgrade. I actually went that route on my CTS-V and skipped the upper. Was able to go with a 9.5" pulley or 30% (I believe) and was above 15 psi.

I've always wondered if there are ill effects from overdriving the AC compressor, alternator, and water pump.

Looks like the belt for the S/C on the LT4 like the LSA is dedicated. Makes it easy to change the diameter without affecting the other components.

 

[Ferzerp]

Btw, the blower was maxxed out with the smaller pulley. Their overdrive pulley did nothing at all.
