Honestly at that power level I think you will want to go with a 28" tire. I believe you will be running out of gear before the 1/4 mile stripe, unless you are revving well above 7k rpm!

what did it run as a manual?

Greenhornet347

Rpm said the 342 it has are good fir the setup..car ran 10.7 on motor making 565rwhp and a 10.3 with 125 shot..now it hasn't been to the track with the twins and new rpm trans..it made 1060rwhp at 6200rpm..

RPM wouldn't suggest a 65 for 1000+ hp. I would expect that tranny to explode after a few passes at best. You need an 4l80 for that power level.

1000+ hooking in an auto is an 8 second car.

Should go 8.80 at 160 mph.Good luck to you.

If gto can make and handle 1100rwhp with the trans I'll be happy staying at 1k...8's is the goal

Rpm used Thier 4l60s in 8 seconds cars.

Hell in that white camaro hey built, they pulled the 4l80e and put in a 4l60 and went 8s at high 150s in a 5th gen camaro.

That one Vette does 8s at 160+ with one.

Clueless on how long it might last. But it's been done.

Unreal

Which vette?

Jeremy@RPM told me anything past 800-850rwhp the life expectancy of a 60 is basically nothing.

Best of luck to the OP, but for a 1000+ build I wouldn't even try to mess with the 60 unless you plan on servicing it often.

My understanding is built 60s are stronger than 65s too

I'm impressed and amazed at the number you made
With a sts kit!! Is that using the stock cold side? Good luck!!

Greenhornet347

Yup car made 816rwhp with the stage 3 60-1..swapped turbos since the one seized and with the same amount of boost and a better tune jumped up to 1060rwhp....I've owned my vette fir 3 years and put less than 500 miles on it..so if it last a year or 2 that's good..it's supposed to be refreshed every year..

Shoaf85

As far as the actual "hard parts" in the trans go, a 4L60 will hold that power if you go with a level 7 or higher. The only problem you will have is the 3/4 clutch packs which will just need a refresh every so often depending on driving style and number of passes!

There are quite a few guys that make around 1000whp that have good luck with them they just eat clutch packs if raced a LOT

here is another.... kept breaking axles so he had to baby it out of the hole!

Damn who's car is that? A member here? He really walked that one out... Probably only a 1.55 60'.



RPM has a level 10 4l60 now with the sonnax billet drum. I would definitely get that option for trying to make it live at 1000hp.

I've been putting 850 rwhp (stick dyno numbers) thru a level 7 for a while now. Not many track passes, maybe about 6-7 passes, but quite a few highway bombs where it goes 3-2-3 shifts wot.. Probably atleast 30 of these hits and its held great so far. We'll see how long it lasts. I have about 4k miles on it as well. When it breaks, it will get the level 10 rebuild.

I don't think the maintenance on a 60e is any different then replacing a twin or triple disk clutch in a stick car... How many 800-900HP stick cars go more then 50-60 passes on a clutch before it's toasted? Same thing for a TR6060, how many hard passes can you make before it needs forks/syncros...? I doubt its THAT much more then a 60e's 3-4 clutches.

I really love the 60e in the car... Can never launch/shift as smooth/quick as an auto with a stick....

ajrothm

OP, you're DEFINTELY gonna need 28s.. No doubt about that.. Unless you're just gonna run 1/8 mile tracks. 160 mph will be way over 7000, even on 28s.. Probably about 7300 depending on how tight the converter is.

And be prepared to pull that converter out and have it adjusted a couple times to get it dialed in.. Major PITA but that's what it takes. I'm on my 3rd converter adjustment.

At that power level with a turbo setup and with a limited tire size, I would think that a built powerglide would be the best option. Any reason you don't want to go that route?

croatbob

i wuda gone glide for 8s. thats me tho
