60' times vs. et

[shockstang]

I'm looking for some opinions and/or facts on this. All things being equal, it stands to reason that the lower your 60' times the lower your et. For example, if you lower your 60' time by .05 seconds, does that mean your et will drop by the same amount? Is there any direct correlation between the two or are there too many variables to be able to say "If you lower your 60' time by X, your et will drop by Y?" Sorry if this has been discussed before, but I haven't found anything on this forum about it.:dunno:

[John4cam]

I've always heard if you drop your 60 one tenth, it equals two tenth's in the quarter roughly.

[somethingclever]

Too many variables to say 100% for sure....


On my boosted car, I saw "x" reduction in the 60' = 2x reduction in ET.

On my n/a car I saw "x" reduction in the 60' = 1.5x reduction in the ET.

[CobraII]

I agree with John, way too many variables, such as, why are you picking up in the 60'? Is it because you spun, played with tire pressure, etc?

All things being equal, if it's a straight improvement in something you changed, I think X reduction in 60' is close to 2X reduction in the 1/4 ET. This is what most of us regular bracket racers see, and we key in on consistency.

way too many variables to say for sure. most likely (as in probably 99% of the time), lower 60' times mean lower ETs. But if you car has no top end or if there is a lot of drag on your car at high speeds, you might not see much improvement at all

way too many variables,


way too many variables to say for sure

so.... what you're sayin is..... there's too many variables?? how many too many?

:rofl:

[White5.0]

^hahaha nice!

ya man, way too many :rofl:

[CobraII]

Eleventy billion. Squared.

:D

[NateSVT]

I have also heard that .1 60' = .2 1/4 mile. That would be badass because then my 11.6 with a 2.0 60' would be a 10.6 with a 1.50 60' which is what I'm shooting for in the summer. I highly doubt I'll run a 10.6 at my power level now but maybe a 10.8.

[ModularMike]

I went from a 13.97 @ 97 @ 2.0x 60' to a 13.64 @ 97 @ 1.79 60'.

[shockstang]

Thanks guys. In a nutshell, too many variables. But the consensus seems to be that there is gererally a greater payoff on the top end over what you cut off on the short end.
If I can cut a Modular Mike 60' time I could be flirting with the 12's.

[CobraII]

What issues are you having in the 60'? Spin? Lack of sticky tires? Manaul or auto trans? Tell us what is going on, maybe we can make some suggestions to help you out.

Your car is non-pi and ran that good, if I could get my 60' down I should be able to be right there with you, I would think....mine are like 2.1's- auto kills it

I thought you had some gooddies for the car and you sold them????


Come on clark...get some 4.30's for that car and a slight stall....you'll get those 60's down big-time.....

yea I did I needed the cash, I'm gonna get some more stuff for it when I can

yeah like tires??

So far, 1.93 is my best 60' time. I'm leaving at 3000 rpm's on Nitto 555r's with no wheel spin. Manual tranny. I've seen guys leave at 4500 or higher, but I really don't want to break anything if I can help it (but who does?) I have never had the car dynoed, but it's pretty much stock. Headers, off road h-pipe, flowmasters, udp's, CAI w/ 93 octane tune and an MSD two step set at 3000 launch rpm. I'm gonna start raising that a little at a time, but don't think I want to leave much higher than 4000.

[John4cam]

How good of a burnout do you do? Nitto's need to be HOT to stick well.

[shockstang]

Just a quick one to warm them up. No long smokey ones.

[AdamantiumSilvr]

...most definately need to bake the Nitto's off, for sure! I've been standing still burnoutin mine, and they got tons of tread life after two years.

[Balaska347]

The manual tranny is your biggest variable. If it was an auto your et would be 2x better then what you gained in the 60ft, or atleast very close

I've been known to put parts "at risk" looking for a few 1/100th's off my 60' :jump:

I continue to try Bob's approach, this year I will bump it up a big notch :rotflol:

:highfive: I sure didn't invent it, but we both keep trying to perfect it :D

I can't wait to try my new stuff too. Your's should be fun this year! :goodidea:

[ModularMike]

Those times were on different days here is what the same day 60ft changes were doing to get rid of some variables...

1st 2nd 3rd and 4th pass that day respectfully:

ET----------MPH-------60'
14.0495......96.26.......1.99 - 3500rpm launch
13.9254......96.46.......1.90 - somewhere around 4500rpm
13.7774......96.86.......1.83 - about 5000rpm
13.6450......97.51.......1.79 - 6500rpm (rev limiter)

[shockstang]

Mike, are you running a stock clutch and drivetain? If so, how is that thing holding together?

[Martin0660]

13.6450......97.51.......1.79 - 6500rpm (rev limiter)

Hell yeah! That's the technique Ed and I were talking about :D

[shockstang]

Well, I guess I got my answer. Give it all she's got and don't be afraid of breaking things. That's what the aftermarket is for.:3gears:

[ModularMike]

Mike, are you running a stock clutch and drivetain? If so, how is that thing holding together?
Stock drivetrain and I don't know if its a stock clutch but its the same clutch that was in the car when I bought it 20k+ miles ago. Clutch is getting old but still works and doesn't slip much. Pedal is pretty damn spongey after a run. The t-45 has seen better days, but then again its a 131k mile stock t-45 that I powershift the balls off of, so thats only expected. Drives fine but once and a while I grind 3rd with the clutch all the way in. Probably could use new synchros, haha.

I was seriously betting $$$ I was going to snap something on the 6500rpm launch but I was pleasantly surprised haha.


Edit: The old tired clutch is the only thing thats probably keeping my trans and rear end in tact.

Word, with 4.10's and stock stall I think i was doing 1.9's. Wake that thing up!

[John4cam]

LMAO

[Martin0660]

For sure that is my approach, but the reality is, I'm trying to move 3200#'s with 140 cubic inches, it's not my primary ride, and I get off on wheels up launches and the looks it gets ;) If it breaks, I consider that the weak link, upgrade, then go find the next one :D It might not be the best path for your daily driver, something you have payments on, or plan to keep a while ;)

That said, you will never beat the feeling of a dead hooked launch off the limiter :3gears:

No doubt, never did crack, but those launches make me keep going back no matter what carnage it creates. It's an amazing thing :highfive:

Yep, one hit and your hooked.

Completely stock suspesion and drive train. I'll be putting on lower control arms before the first track day though.

If you plan on hooking, the 1st mod would be weld on subs. Verts flex a good bit.:thmbsup:

Would this also help to alleviate wheel hop? Is this something I could do myself, I can weld, or is there more involved than merely welding after the appropriate prep work?

[Sonic03snake]

Is this something I could do myself, I can weld, or is there more involved than merely welding after the appropriate prep work?If your a good welder you should have no problem. The hardest part for most is being able to get the car high enough and completely level sitting with the weight on the tires. A drive on lift is the best way to go. Never weld them on with the car not loaded on the suspension. These will not help wheel hop.
