You're right if it's too loose but really REALLY wrong to say that if the combo needs it.
Why would you make such a statement
I wouldn't mind hearing the reasoning behind it.

An I'll add even solid roller N/A cars, one's without a dry sump set up and spinning under 8k would not need and will lose performance with such a high stall.
I hear ya... but explain why the fastest cam only and h/c cars were running the 5500 8 inch ati converter. Must have been totally wrong.

Oh and the gulf coast car that just went 9.20's or something like that n/a a little while back.. he picked up going from a 5000 to a 6000 converter. Must not work.

we don't have to agree about this JL and I'm not familiar with those cars. I can't imaging a cam only or h/c spining that high living too long regardless and the 9.20 car you speak of is hydraulic? If so that's impressive.
Can we agree that unless the converter puts you in your in your powerband it's not optimal? And of course all N/A do not need 6k verts.

All I'll say.. is that the race isn't won in the first 60 feet.

I was just ticked at my converter from Friday night and in a bad mood.

I need to gear my converter properly (the 2 work together) and see how much it tightens up. The converter used to work really well with my old set up off the footbrake with suspension preloaded. Cut some hellacious lights. Since then , i've made some changes to other parts of the car and working out the bugs again. Change one small thing, and it can throw the whole deal out of whack. Always a work in progress.

heads up, 60' sure helps. bracket style, consistent 60' is what matters..

Tell that to the stock eliminator guys
You sayin' short time isn't important in a race? Especially for an N/A car?

I'm saying.. that if you have 1320 feet to race, and you only focus on making the most out of 60 of the 1320, you will get beat by cars that are making more out of the other 1260 feet of the track.

a tiny fraction of a second per foot x 1260 vs a little larger portion of 60.. the guy that's got a car that runs stronger for 1260 feet is going to win.

rail cars and funny cars prove that weekly. Mike Edwards proves it weekly, his 60 foot times aren't any better then anyone else.. it's what happens after that which is where he shows the gains.


Stock eliminator cars aren't the end all be all of racing, what works for them is only a small portion of the big picture. Things that work for them, do because they have LIMITED POWER. We're not even close to that.. we're making a TON more power then those guys are via alot bigger motors, we have ligther cars (or no weight penalty for the engine setup etc) which all adds up to the same phiosphy not working.

Do what ya want, but as long as you only focus on the 60 foot time you will never go as fast as you can.... and the more the car relies on that 60 foot time to go fast, the more it relies on the track being good, get on a shitty track and watch what happens.

short time (first 60' of acceleration) and reaction time is about all that matters

.1 in 60' is .2 in 1320
.1 in 1/8 is .155 in 1320
.1 in 1320 is .1 in 1320

the game is about acceleration

Turbocharger may change the rules of thumb a bit though.

If you're talknig bracket cars CONSISTANCEY helps, car can 60 foot like a pig that doesn't matter. Cut a killer light and have a car that repeats, and you WILL go rounds.

Hell that's why the 12 second bracket cars run 33x18 inch slicks, they barely can get them spinning in the burnout box but they repeat like crazy... too much tire not to hook 100% of the time.

I'm talking about heads up all out type racing... 60 foot time always helps, but I'd rather have a car that rips up the next 1260 and comes out a little weaker then a car that sets the world on fire for 60 feet then doesn't do **** the rest of the way down the track. Plus, that car that runs the first 60 like nuts is great and all until the track zambonie srcubs all the track prep off from impapa day's cars pissing fluid all over the track.. once that happens they all start blowing the tires off and the car that was set up to be a little soft in the first 60 but haul the mail the rest of the run cleans house.

Car should be set up to run what the track allows you to. It's ideal for the car to be able to leave hard on a good track and to scale it back on a bad track. Even your rail and funny cars do that, which we're nowhere in the same league but since you mentioned it.

I'd rather lose spinning the tires outta the gate instead of having my car leave like a ***** and watch the other guy walk away ANY DAY!!
It's easy to say let the car leave soft when you just spent 1/2 hour in the pits changing your nitrous jets.
I'd like to see your strategy work without the bigger jets or extra boost.

I don't think you can comment on 60's JL, you're racing strategy, as you're saying, isn't suspension setup, track conditions, air pressure-whatever, it seems to be all about how big a jet to run that day. And that's fine, if that's how you want to race but it's not everyone's wish to do so and it's certainly not the way to get the best ET out of a racecar.
