Depends on in which gear and at what rpm you will see 130mph.

My stock geared C5 Z06 would hit 140+ in 4th gear, so it was lacking a bit in 4th gear.
I really wanted to see what a 3.73 ratio would do for 60-130, since it would have lowered my mph in 4th gear from about 140 to about 130-132.
I was expecting a few tenths improvement since the car would have been pulling a bit harder in a 3rd to 4th gear 60-130 pull, but I never got to try it.

Close-ratio might be a plus, as long as you can go full throttle at around 45-50mph and still hit 130 with only one shift.

I wonder if a 28 inch tire will go 130mph with an M6(base or z06) gearing and 3.42's in 3rd gear? Then you might not have to shift if you have a lot of power.

I put together a spreadsheet to compare that very thing.

3rd gear, 3.42, 6500rpm will give you

M6: 122mph
M12: 111mph

Same scenario at 7000rpm will give you

M6: 131mph
M12: 120mph

This is based on a function I came across a while ago, and it is pretty accurate.
Hope this helps.

I would imagine it'll be something in the high 3s taking it

I was more posting it because Old Motorhead was curious when another 60-130 event was going to be held.

Imagine a car (UGR lambo) that is almost a full second faster from 60-130 than a built 427 blown auto vette with over 1000 rwhp (1swtride's car)...that is just silly....I know what .9 seconds is like on a drag race...its embarassing to say the least...so from a 60 kick I imagine its pretty bad too....several carlengths...

5.88 is very fast obviously, but ther are always those faster...unless you have $400K wrapped up in a UGR Lambo I guess! lol

1swtride's car has gone faster @ 8.57 in 1/4, but it didnt have the 60-130 timer in it then. That time recorded was during 9.0ish 1/4 mile times.
He is back to a new T6060 trans now, so hopefully we will see some nice six speed times from him this season.

I logged my C6 Z06 (507whp) a quite a few times 60-130mph. It is tough to gauge where you sit at in the group, since they allow up to a 3% grade. On a flat surface my car's best is a 8.08 down here in wonderful Florida humidity. It averages 8.2.

I have logged quite a few stock C6 Z06's and they average 8.90-9.1. A buddy with a cammed Z06 averages in the 7.6-7.8 range. Fastest thing I have logged so far is a ZX-10 at 4.84, but that's not a car...lol

one thing about the 60-130 is that it eliminates 60ft times out of the equation .. a car going 9.1 @177 (UG's Lambo) with a 1.7 60ft will have no bearing on 60-130

you could have a car go 8.2s all b/c of the hole shot and still not run a 3.0 60-130

You're numbers are great. For comparison purposes, I'm 1SwtRide on the referenced list with ECS' hardcore package on my 2006 C6Z06 which, at that time, had a YSi making 1000+ rwhp and close to that in rwtq. However, that fast time was at the track running a powerglide and "semi-slicks". This is the thread when the car was YSi and got that 60-130 and a 8.78 1/4 mile time.

http://forums.corvetteforum.com/drag...1-at-indy.html

After that, Doug drove the car to a fast 8.57 after fitting the Novi 2500. I didn't send the PerformanceBox with Doug so I didn't get the 60-130.

http://forums.corvetteforum.com/c6-z...post1579318759

The best I got prior to that with a Z06 6 speed was 4.88 on NT-05rs. Here is the link 4.88 run here on CF.

http://forums.corvetteforum.com/c6-f...mph-times.html

I've since swapped out the powerglide and the car's getting put back to a 6 speed with ZR1 transmission and some other special mechanical and electronic goodies courtesy of ECS

By the end of this month, the car should be dyno'd on both ECS' dyna-pac then on some rollers for the over approx. 1100 rwhp/rwtq tuning by Doug@ECS. Once it warms up, I'll be aiming for better 60-130 etc times and working on my 1/4 times to try for *fingers crossed* low 9s / *pray to horsepower god* high 8s with a six speed. I'll be sure to post up.
