C7BB

I don't need to google anything. I've owned both cars, I know which is faster in stock form.

Higgs Boson

of course we need to do a heads up race, that was just a joke, right?

LT1_E85_Corvette

I wasnt questioning which is faster in a stock forum, the Z06 would win hands down. MY questions is with headers and E85, I believe I should be able to outrun a STOCK Z06.

Re-cape:

Stock Z06 vs Headers/E85 Stingray

Who would win?

C7BB

Z-06... With traction. Can the Z-06 run drag radials?

Higgs Boson

Driver's race with the equal driver situation going to the E85/header C7

C6Z - 11.10 @ 125 (on avg)
C7 - 11.50 @ 120 (on avg)
Difference .4 and 5 MPH (40-50 HP)

C6Z - 505 HP
C7 - 460 HP
Difference (45 HP)

Stock C7 - 415 rwhp
Yours with headers and E85 - 473 rwhp
Gain - 58 rwhp

So it comes down to shifting and tires

C7BB

Don't forget the 3100lbs C6 vs 3300+lbs C7 . Weight matters too.

LT1_E85_Corvette

Awesome breakdown

I shift like a mad man ( I like to tell myself ). I hope I can get a chance to make it happen before I get to many more mods

Higgs Boson

C6Z 440 rwhp
E85 Headers C7 - 473

33 rwhp
200 lbs

10hp = 100 lbs

C7 has 13 rwhp advantage with weight consideration

C7BB

In my opinion you're a little light on your Z-06 rwhp guesstimate. I've seen them go from low 440's to as high as 460's bone stock. Those are rev happy motors too, so with all this taken into account, I'd still put my money on the Z-06. I respect the op's numbers as they are quite impressive, but still not gonna take a properly driven Z-06.

That's fine, just going by google searches on C6Z06 rwhp. Sure there are factory freak cars and some in the 10's as well, but most run low to mid 11's, not that much faster than a C7.....

No matter how you slice it, 45 HP and 200 lbs separate the two cars when stock. That is like 65 HP. If you bump the C7 by 58 rwhp, that is about 65 bhp. Now you have a driver's race.

C7BB

Fair enough... Not trying to be argumentative, just my opinion.

LT1_E85_Corvette

If you look at the dyno chart I provided, down low, i'm making a much healthier power curve, we are all talking peak power here, which is only relevant until after 5250 rpms. the LT1 with my mods when compared to the Z06 and a tune, makes 25 more HP and 50 more tq the whole power band under 5250 rpms. That's a HUGE difference. only when we get after that point does the LS7 start to pull out a higher peak number.

These LT1's are really crazy different motors when it comes to early power, which I think would really help in the quarter mile, but not as much in a roll race.

C7BB

See that's where you and I differ on opinion as to which car would win the short race... The LS7 comes alive in the upper rpm range, which coupled with the lighter weight of the car will accelerate more quickly off the line... And as you know, the car which gets out front the quickest is the hardest to catch.

LT1_E85_Corvette

I have shaved some weight on the Stingray, I think based on some other people with my mods trapping 127-129mph, that it would be a drivers race from a roll. from a dig, the LT1 has a large advantage with early power being much more usable.

Crazy to think how a motor designed in 04-05 is still so powerful over 10 years later

C7BB

We could debate this 100 different ways... But, you and I know both cars are pretty amazing in their own way. I certainly wouldn't discount either car in any race, and, it's still fun to debate which car is faster.

I'll run my Cammed C51 against Z06's this weekend at Road America. Camming this car makes the dyno much more like a Z06 pulling hard all the way up to 660 rpm.

I'm making 500whp on a Mustang, this thing should pull Z06's down the straights at Road America no problem.

C7BB

That'll be interesting... Keep us posted.

C7 turns better, C6 goes better... been witnessed and evidenced time after time.

For the highway pull nonsense we do, C6 handily beats C7.

Higgs Boson

I dont think anyone is saying otherwise. We are comparing a C7 with headers and E85 to a stock C6Z. Also a 6.2 vs 7.0 though, so that makes it even more cooler to me.

RC000E

I'd find this all far more interesting if it involved laptimes and not bs robot straight racing.
