Slightly modified? The only thing they have in common is the block. Forged internals, titanium valves, different alloy heads, blower, yada yada yada

 

Thanks for all the replies people,

I have always modded my cars so will do the same on the Vette. My friend is supercharging hig 2005 mustang GT (Vortec) so have to reply to let him know there is anly one true american sportscar

If I read all the info it is better to buy a LS3 which you can mod almost all you want (Gm are coming out with a kit to almost turn it into a LS9 I have read somewhere). Added bonus is you can also remove the roof in a LS3 C6.
The wider body + better suspension is more attractive in the Z06 which I probably won't mod mutch in the engine compartment.

Best combination will be to mod a Grand sport.... best of both worlds I suppose.

PS : Weather is not that good over here, started freezing/snowing here.... at least a white Christmas !.

Thanks again for all the info, I will keep surching on this forum for more info.

Greetings,

Mark

 

You can buy an LSA for $14K ready to install from GM and get 550HP.

 

Exactly. How fast do you want to go? And what are you willing to give up to go that fast?

How much money which you will never see again, are you willing to spend on modding?

How much risk are you willing to take on mechanical failures not covered under the manufacturer's 5 year/100,000 mile warranty?

Already the Z06 is capable of going quick enough and fast enough to get you booted from many, if not most tracks if you don't have a roll cage.

As you mention earlier, multiple drivers have gotten the car into the 10s on drag radials alone and with no other changes to the car, and one owner, a gentleman who has owned an '06 Z06 and now an '09 Z06, Dr. Ron, has managed to put not one, but BOTH of those cars into the 10s on drag radials and no other changes to the car.

Results like that tell many of us, that all you need to do is learn how to drive a Z06, and it is going to go as quick and as fast as many of us are going to want for a primarily street driven car.

You may not run consistent 10s like Ron and the other half dozen Z06 owners who have done so with no other changes than drag radials, but if you learn how to drive it, you're going to beat many, if not most, (you'll never beat them all, even if you mod your *** off, as there will always be someone quicker and faster) and you are still going to be able to drive it home.

You'll still be able to take a road trip in it if you want, coast to coast if you want, with your wife or girlfriend in it, and not worry about it breaking down on you and no one being willing to touch it while you are on that trip.

You'll still be able to take your wife or girlfriend out to dinner in it without her feeling as though she is riding in a hotrod belonging to some teenager, you'll still be able to drive it to a wedding reception without waking up the whole neighborhood, with headers and Bullets, and you'll still be able to keep your warranty.

All that, and running mid to low 11s if you can drive it, and quicker than that if you really learn to drive it and have good conditions????

What a deal.

 

BTW Ranger just went 10.74@129 today on drag radials in his stock Z06.

I don't care how much bragging rights a modded LS3 puts down on a dyno, you have to respect what a STOCK Z06 can accomplish on drag radials.

 

You gotta be kiddin me.

10.74 @129 bone stock and on drag radials??????

Well. Ron said in his post describing his 10 second run in his new 2009, that had conditions been better, he would have had a shot to rearrange the stock on drag radials record.

I guess Ranger beat him to it.

 

Only thing I might add on a Z06 in a nice exhaust, otherwise I will leave it alone, already fast enough.

Man snowing a lot today in The Netherlands... not really weather to drive a Z06 with those 325 rear tyres....

Gr,

Mark

 

Lets let Ranger drive a modded LS3 and get some #s... seems like nobody on the fast list with a LS2 or LS3 can even compare to Ranger's talent.

I went here and entered the Z06's weight/flywheel hp:
http://robrobinette.com/et.htm

Says 11.24 in the 1/4mi. So obviously that calculator is wrong by a whole half-second since Ranger ran it in 10.74. What I'm curious is, there are guys with 550rwhp running high 10s... I guess I'm torn between two things:
1) The stock Z06 with DRs and a great driver can run 10s
2) A modded LS2/LS3 with DRs and a questionably good driver can run 10s

It's amazing that the Z06 can do the 10s, for sure, but what kind of #s would we be looking at to compare if its more about the driver? It reminds me of the track records, 7:22 for the viper, 7:26 for the ZR1, but what it boils down to is NOT the car... it's the driver. The car has limitations, sure, but in a computer simulation where the precise speed is reached before breaking, the perfect turns are accomplished, etc., what would the ZR1 actually get? Somewhere below 7:20 possibly?

It's just an unfair comparison to say this # was achieved by this guy, vs. this # achieved by the other guy, it's a drivers race and the better the driver the faster they'll be in the 1/4mi. Look at magazines, those guys testing out the cars barely break into the 12s

 

With regard to the below, one can point out that some of the modded LS2s and LS3s you allude to are automatics with high stall converters and gears. That might even up the comparison some.

At any rate, what Ranger accomplished is remarkable.

He has demonstrated his own driving skills as well as having demonstrated the astounding potential and capabilities of the Z06. One of the great Vettes of all times without question.

 

I completely agree with that.

 

10.74 is incredible.

 

10.74

Dang, I think I'm going to have to trade my LS3 for a new Z06. Hey, wait a minute (goes to check in the garage), I DID ALREADY! lol

 

Don't forget that a modded LS3 that makes a little more power than a Z06 will still be slower. The Z06 will still have a better powerband. I wish I would have gotten a Z06

 

Just so you can rest easy, first Grand Sport to blow an LS3 has cropped up. This throws a wrench into the whole....LS3 is much stouter and never fails camp.

http://forums.corvetteforum.com/c6-c...-3k-miles.html

To be fair it can happen to anyone. Now keep this in mind, if he had a tune on that new Grand Sport......HE be paying the bill for a new engine out of pocket.

Another great reason to pick up a Z06, it's a 10 sec car with full warranty.

 

You do realize that isnt the standard LS3. that is the hand built LS3 with the forged crank that shares the same plant as the troublesome ls7. Us standard LS3 guys still enjoy our stout motors

Also the z06 isnt a 10 sec car stock, its a 10 sec car with slicks. Thats a big difference. The zr1 is a 10 second car stock.

 

Both the Z06 and the ZR1 have run 10 second passes on their stock tires.

 

Really? who did a 10 second run on stock tires in a z06? Ive only seen the zr1 do it.

 

Jamie Furman ran a 10.98 on stock tars.

 

Not to dimish that, because that is incredible. A magic launch in magic conditions to make 10.98 one time doesnt make the z06 a ten second car stock to me. To me the z06 is a low 11 sec car stock and the c6 is a low 12 sec car stock.

 

Fast enough for me!
