How much G your Corvette pulls?
Mmmm :rolleyes: , stock 1982 Corvette numbers are 0.82 G and 59 mph in 700ft slalom with its ancient white lettered Good Years . 
With its neutral weight balance, a C3 can make much better numbers just by switching to hi-tech z rated tires, and with the availability of complete hi performance suspension packages from many Corvette shops, I think that there are more Z06 C3s than the C5 Z06s! :thumbs:
:reddevil Now: bring your G-tics out and see how you're Corvette will
perform and tell us about your suspension mods and tires.
:D :thumbs:

Re: How much G your Corvette pulls? (2BAD)
sold my g-tech so i don't have solid numbers but i'll just guestimate on street tires i pull ~.95, on slicks it's probably more like ~1.1-1.2.
to back that up, these are the mods i've done:
17" wheels/tires
460# springs, cut 1/2 a coil to lower the car 1"
330# rear spring with lowering bolts
all poly bushings
1-1/8" front bar
7/16" rear bar
koni shocks
solid welded the seams on the bottom of the frame
covered and welded many of the holes in the frame
fabricated a third crossmember in-line with flywheel to tighten the framerails

Re: How much G your Corvette pulls? (2BAD)
I'm more interested in g's experienced in a 1/4 mile run. Assuming constant acceleration (I realize this is not realistic) in the 1/4, if you reach a speed of 110 mph, you've only experienced about 0.3g's. To maintain a full g of acceleration through the 1/4 you'd have to finish at about 200 mph!

Re: How much G your Corvette pulls? (VolVette)
I have not had much of a chance to measure Gs in the Corvette, but it can outhandle my Chevelle, and that car pulled over 1 G. Running at Willow Springs, Turn 2 is a 470 foot radius turn that I ran a consistent 85-87 mph, with some runs possibly over 90 (I think my speedo is 5% low, so potential speeds up to 95 mph). The math says 1 G to 1.1 G.
As for 1/4 mile G forces, remember that the G force is max at launch, and then drops down as you go down the track and shift gears. You can look at 60 foot times, as well as splits to guesstimate Gs. I've done a little playing with this (a buddy once asked what kind of Gs are pulled in a top fuel run) and have some estimates.
A top Fuel car probably hits about 8 Gs at launch, and might go as low as 3 Gs near the end, and averages about 5 Gs. A 12 second car with a 1.7 second 60 foot time will see a max of maybe 1.25 Gs at launch, then settle down to the 0.8 G to 0.7 G range, averaging 0.6 G for the run.

I'm really impressed with the G numbers :eek: but nobody talked about slalom speed :confused: I think most of us ignore it .Anyway do you think that there are more Z06 C3s than the C5 Z06 ???

Re: (battsup)
im a little confused here...so bear with me if im wrong...
dosnt the C-6 pull 1G?
if that is so...how the heck do our antique C-3's have a chance at even half of that? :confused:

Re: (battsup)
What's a Z06 C3? Are we talking about FE7 equipped cars?FWIW, a 1976 Motor Trend article (other magazines used the same article) on the "new" 1977 Corvette listed the slalom time as 12.5 sec.
I'm a stranger to slalom, so I have no idea what that speed means. The car they tested was an L82 with automatic trans, FE7 option, and GR70x15 radials.

Re: How much G your Corvette pulls? (2BAD)
It's not because that somebody is canadian, or because there is a c3 Z06 :D
:lol: it's just because I think that with the reasonably priced suspention kits for c3 Corvettes we can make many c3s handle almost like a Z06
:blueangel: Anybody agrres ???? :crazy:

Re: How much G your Corvette pulls? (Chuck Harmon)
I was once a very vocal proponent of this thought; but, after driving a ZO6 for a year I must concede that I don't think a C3 can be equal to a new ZO6 in the handling department. Tires will get it close, a good driver can overcome the handicap, but everything else being equal, the ZO6 is one incredible handling machine.

Re: How much G your Corvette pulls? (Darkness)
Paul,
You're right about the suspension geometry. The Guldstrand 5 link will get you very close to the merits of the C5 suspension and will allow coil overs; however, Guldstrand states that the coil overs have to be too short to fit and don't really work as well, certainly not better than the trans-leaf spring.
To stiffen the chassis all you really need is a full roll cage, but you will give up status as a "door slammer" and must now enter and exit Dukes of Hazard style.

Re: How much G your Corvette pulls? (Chuck Harmon)
I sure know how many G'sss My Corvetts pull from me.
Every time I fill the car up with gas I say Gezzzz.
Guess we are talking about a different G's

Re: How much G your Corvette pulls? (Tom 4108)
I have seen coil overs on C3's but to tell you the truth I dont know if they fit good or not. I think I saw some on ACP's web page. I'll take a look at it :thumbs:
Yes, a roll cage would stiffen teh chassis but the street driver wouldn't want that. Maybe some subframe connectors or so.

"revised suspension geometry" :smash: That makes think of VBP Performance Plus System .It completly changes the front suspension geometry and revises the rear. :reddevil

"I forgot, and it will ONLY costs you $$$2000!! "
What are you looking for; improved performance for FREE or just less than $100.
You can probably get a C3 to handle better than you'd ever need on the street and spend less money than on a new Corvette, but you'd probably never run as well as a Z06, and certainly, 30 years of technological improvement won't come cheap.
