C7GrandSport

C7GrandSport is finally "done". Last additions being an ECS Supercharger by The Vette Doctors and custom underhood insulation by RPI.



So it was time for a photo shoot Friday with Richard Prince of Corvette Magazine. Richard had photographed my '73 big block and '63 split window in the past.

We agreed the weather forecast looked great and we'd meet in the late afternoon. I spent most of the day cleaning on Thursday and drove the car to work on sunny Friday morning.

Then the dark clouds rolled in during the afternoon. Then it rained. Then I wiped the car off. Then it started to look brighter. Then it rained again. Then I wiped the car off again. Although the sky still didn't look too encouraging, I set off to meet Richard.

Fortunately, that was the end of the rain and he got to shoot against varying lighting conditions, as the cloud cover kept changing. It also produced a beautiful sunset. I'm sure he got some great pictures.

I figured I'd photograph the photographer ...











I'm sure his will come out better than mine ...

You've got a beautiful car and I love what you have done to it. So when will the article appear in Corvette Magazine?

C7GrandSport

Thanks.
You never know. My '73 took almost 2 years to get in, '63 was a lot quicker. Depends on what other cars they are running. I would guess sooner than later, since modified C7's tend to sell magazines for them!

Let the bitchin' about how it isn't a GS begin!

Richard shot my car for Corvette Magazine a few months ago. My car made the cover of the 100th anniversary issue which is the October issue.

Congrats.

She's a beauty!

It's months since my last round of that. Now I've come back for more

HP jumps from 570 to 713

I'm sure 713 is what he is stating at engine, whereas 570 was at the wheels.

It would have made more sense to just call it what was verified... 570rwhp or "over 700hp at the crank" would have been fine

When people who don't know anything about dynos ask how much horsepower my car makes, I just tell them it's "about 500"

I don't guesstimate based on my last dyno number and tell them it's 499 or estimate that it should be closer to 525 on a milder day

I came here expecting a Stingray with Z06 engine, brakes and suspension...

C7GrandSport

You're the winner!

713 flywheel horsepower - 20% drivetrain loss = 570 rear wheel horsepower

C7GrandSport

Give them a few more years when C7 sales start to slow

The car is brilliant!

huh? 20 percent of 570 is 114 you have 684 at best

johnnypro

...am I missing a joke here or is this guy serious?

4GS7

Math, how does that work....

X*.8=570

X=570/.8

570/.8= 712.5


The C4 Grand Sport had black wheels with a polished lip. Might I suggest a silver rimblade to recreate that look?

C7GrandSport

For those Little Rascals fans, "Algebra, this is no place for you".

C7GrandSport

I was thinking of those, but not sure how durable they are. As you probably already know, you've got to clean black wheels a lot!

What is 10 percent of 570? It 's 57 it not algebra!
Your all wrong and it's .2 times 570 equal 114 20 percent of 570 is 114.
114 plus 570 is 684
You can't figure percent of 713 when he is guessing the 713! 570 rwhp is the known
Duds!

Next lesson!

No it works like this .. (570rwhp , what he made on the dyno)+ a max of 20% drive train loss = 684 hp at the crank
