Was wondering what some of the best 60ft times out there with a 4l60e?

 

I cut 60s in the 1.4s on stock suspension, and stock trans other than a converter. Im definetly looking forward to some 1.3 and 1.2 60ft times if the trans will stay together a bit longer. Then it'll be time for a built 4l60e.

 

Thats what i was looking for. I am going to do an auto swap this winter and i am trying to make up my mind with either a th400 or 4l60e. What kinda converter were you using?

 

ill pm the details.

 

Go with a turbo trans or a 4l80e. You might as well burn your money if your going to want a 4l60e that'll last behind some power.

 

It's not the 60 foot I'd be worried about, it's what happens when the first shift has to occur, and then when the 2nd one has to occur

4Ljunkie transmissions are just that, junk. good if you're under the 400 rwhp mark, anything more then that you're on borrowed time, period. I've heard so many claims of this level of power and that, but at the end of the day... none of them last. Sure they "might" make it down the track for a day... but I don't think they do that for more then 1 or 2 before having to come out of the car.

That to me, would get real old. Mine as well leave a T56 in the car and just enjoy breaking that on a rather regular basis.

 

4L60E can work well and last if built properly

I have a FLT unit and street drive my car often and see good track time in the 1.40 range NA and low 1.3's N20 without issues. I have many other cars doing it time and time again with FLT 60's as well.

many of them full weight or better street cars

1.32 60ft @ 3400 #'s 396ci 200 shot on 275/60/15 Radials / my car 97 Z/28

1.42 60ft @ 3800 #'s going 10.4@130 H/C w/ D1SC on 17" Radials / 00 SS : customer not on forum

1.37 60ft @ 3800 + lbs 9.62@139 H/C w/ F1A on 275/60/15 Radials / smokenz16 / Z/28

1.44 60ft @ 3600 #'s 10.4@130 H/C 150 shot on 275/60/15 Radials / my dad's 01 Z/28

1.32 60ft @ 3600+ #'s 9.6@142 416ci 175ish shot on 275/60/15 Radials / Z8's 01 SS

low 1.5's @ 3600ish #'s 10.4@130ish 6.0, cam and TT / 70 Chevelle / INTMD8

these are right off the top of my head and again have many street miles as well as track passes + I know there are many more of my customer as well as forum members

I hate when people knock the 60E because they have been to the wrong builder and seen them fail.

 

thanks for all the input. I like to drive my car a lot and it is full weight. On a 200shot it made 705hp 825tq. I would like to hit the 9's next year.

 

What kind of tranny did you make that power through ? 700rwhp is 9s all day long.

 

im pretty sure hes running the stock 6speed.

 

I have a 95 LT1 that made 430HP on Ed Wright dyno last spring with a bad MSD opti so I have no idea what it is really making because at about 6100 Rpm it was breaking up. It has been at this level for years and we took it down to him because I wanted to see if he could work his magic and see if he could get me more. That said this car was raced from early 1996 with a 355 and 2 wet kits and then to the 398 Na most of the time and a dry shot every once in a while thats in it now begining in 2000 and is mentioned above and goes very low 10's NA and easy 9s on a small shot and never broke anything untill this year. It was freshened by a local trans shop every other year and never needed anything more than clutches and steels and a kit. That trans has good steels and clutches, the servos, a shift kit and a beast sunshell nothing custom or fancy. It ran fine for thousands of passes untill this spring when it broke a forward sprag coming out of the burnout box. Then a couple of races later it ate a planatary which I feel was missed and was caused by the previous incident. My local trans guy pissed me off (I also subbed out rebuilds to him from my shop and we had a major problem that could not be over come so he had to go) I needed a new guy to do my trans so I went with FLT and got them to do me one from scratch in june. Stuck it in the car and runnered up at a big money race that weekend. Since then I have put over 200 passes on it and won more money than I paid for it. I run the car almost every weekend and all 3 nights if there is a place to race. My 4L60E does not scare me a bit. We are going to be making more power next year and the same trans will go back. I doubt if FLT thought they would not hold up they would give the warranty that they do. If you have huge twin turbos or are hitting it with huge shots of nitrous maybe it wont work. But in my car it does just fine both the high dollar one I have now and the low buck one that was in it before.
Take care.

 

Somehow I missed this post.
I too would like to hear about this engine. With that kind of power you should already be way in the 9's maybe even 8's if that is FWHP thats still 570 or better to the rear wheels. I am no where near that NA and I can go low 10's with out a problem on a good track with what I would call not the best air conditions. Is this a different engine than you posted in the dissappointed 408 thread? I see you are in So IN. where do you race at?

 

Well, I'll put this out there again then, to all the tranny builders, as I have done before.

I'll have a 2900 lb car, with enough power to run well into the 8 second zone. If you think your 4l60 will hold up, send one to me and I'll put it in my car, and give 100% feedback, GOOD OR BAD, as to how it performs.

I have a solid roller 408 here that with a little nitrous help, will make PLENTY of power to get into the 8 second zone, and spin a good 8500 rpm, no problem. Or, I can put some dish pistons in it and boost it via a gear driven procharger/vortech, or I may just build another entire motor setup, regardless, it will be a solid roller 8500rpm deal. I'll make 1100 at the flywheel, one way or another.

Car works, always has. I have a VERY good tuner, that will be 100% right no doubt in that department.

If you think the tranny will hold up... send me one. I'll cover the shipping to and from you, when I have to send it back. Send me a tranny, and I'll put it in my car and we'll see just how well it holds up, in a race car.



I've put this out there in the past, and not once have I had someone willing to send me a 4l60. I've had offers for Th400's, Th350's and glides, and an offer to put a 4l80 in, but noone wanted anything to do with sending a 4l60.

It's time to put the product where all the talk is, and see if it will stand up to the hype.

 

9 year old 4l60e built by speed inc.

3600 lb car 1.41 60ft on motor. Has several hundred passes in the 1.4 60ft range.

I think all the haters need to get a better trans builder.

I think keeping it cool is the key. I run the biggest trans cooler I could find with a trans pan that holds two extra quarts of fluid.

Trans has never skipped a beat.

 

Chris1313 went 1.29 60ft saturday at Great Lakes Dragway in Union Grove Wisconsin saturday,H&C 346 with a Yank SS4000- 30xx lbs.His trans has 50-60 runs on it all in the low 1.30 range.Like Larry from Speed said, its what is in the trans and who built it if you want it too live.

 

I've watched 400 hp h/c cars beat them up... I've never wasted my time putting one in my car...


Like I said. Someone thinks they can get one to live in a race car, time to put your work and parts to the test, send me one and I'll see what it can take.

From my exp.. as soon as I say 8500 rpm, everyone (tranny guys) run and hide.

 

FLT here as well & Daily Driven

1.45 60ft @ 3550lbs 10.5 @128 C + 125 shot, driven to the track 80 miles one way.

This is my second car with an FLT 4L60 and I have been very happy with their transmissions.

 

Its a NCR built T56

 

it is the same 408...with 110 octane i gained 25hp on motor alone. i didn't get a chance to get it to the track with some good tires this year or on the nuts for that matter. I race at ohio valley and us60 in hardinsburg. I am putting a bolt in cage this winter and hopefully a built 4l60. Does anybody 60ft this well with performabuilt tranny's? I appreciate all the input guys.

 

I know you will surely be happy to go with a 60E or 80E over a 3 speed for a street car. I have been there before and will never look back as it's so enjoyable to drive to and from the track at 60+ mph.

JL for your more race oriented car you really don't need a 60E and the reason why someone is not going to give you a trans as you have asked is there is no need to do so. They have their info that they work already from many of their current customers / vendors.
