Hello,
I currently have an ls3 setup, which put down 454rwhp in the last car it was in. I would like to get to 650rwhp. I am looking to install a built t56 trans with this motor in my 68 Camaro. I was looking at either a large single or twin turbo setup. I was told after abouut 475rwhp, a turbo setup with be all over the place at the track? Someone told me the trans will feel like a jackhammer and to go auto trans, or go with a supercharger vs a turbo?
Anyone with real world experience?

Do some searching, this has been discussed alot lately. Im putting a t56 in my car with a turbo ls3. I know its not ideal but its what I wanted for a 80% street/20% track car

All over the track after 475whp? Not hardly. Check out this video of a member on here. He can correct me on the specs if I'm wrong:
-580ish wheel horsepower
-6 speed manual

Thats what Im talking about! Having a real hard time giving up my manual and paying twice as much plus adding weight to get the auto.
I am wondering though if there is any truth to "it makes the trans feel like a jackhammer" It seems like it may from the video?? Any way to ask the member in the video?
Thanks alot!!!

auto is better for a turbo car for a few diff,reasons, it might be all over the place if you dont build up the rest of the car lol

I don't understand the like a jackhammer comment. In what way? If you mean that it pounds concrete that is pretty apparent I too intend to run a T56 on a high horse setup and 10.50 is good enough for me

Same here, my rear end and suspension is ordered, and i plan on keeping the T56, its more fun on the street. and id be happy with a 10.50 also .

thats mine, car has gone a bunch of passes in the 10.4's, going for mid-high 9's with the new setup. made 578 before, shooting for 700+

not sure about the jackhammer comment but the launch and 1-2 shift are pretty damn violent with a manual, cant wait to see what low 1.4's feel like. if theres a weak spot in the driveline your gonna know

hey tally, is your T56 stock internally? What clutch are you running and thirdly, what rpm were you launching at in that video?

Thanks man

I think stick to auto is mostly how you want your outcome to be and alot is personal pref, but the thing that plays the most in to the fact of a manual is the componants, you have many clutches to choose from and that alone will change the "jack hammering" effect, the surface area, centrifical forced an so on, ive seen a few guys hit 7's with a clutch assisted dog box and their run is for the most part smooth. check out "G-Force Transmissions and Long Shifters" they deal with alot of fox body mustang guys but see what they have to offer.

1) bone stock, never been opened. it along with basically everything else in the drivetrain is currently out of the car so i will likely tear it down before i put it back in as it hasnt been too happy going into fourth at the track. i also want to put provisions for a sprayer in it. no issues on the street though which is odd. cant complain, has 110k miles on it

2) monster level 6, gm slave, tick master. love the clutch, makes some funny noises when its cold outside but drives great and shows no signs of letting up. killed my spec 3 the first trip to the track after the turbo setup and swapped this one in. has about 5k on it so far

3) i generally launch on the 2step between 5000-5200 and 1-2#'s of boost. hoping to hit it harder with some new rear suspension when the car is back together

ok awesome, thanks dude. im running the diamond stage 2 good for 600whp according to TDP, hopefully i dont smoke the ******.... lol im gonna buy a 2-step for mine also, i dunno if ill build boost with a procharger though.. i doubt it.

Blevinator

I think by jack hammering he was saying that between shifts boost builds, then hits hard?

I bought a McLeod RXT twin disc clutch, so will see what happens!

running a t56 can cost way more than a built auto, tally, you can row some gears bud, op if your going to be on the track alot auto is a better way to go,i love my 6 speed though, mine is more of a street car and i have to row gears in a street car, auto is gay on the street lol

650 wouldnt be deemed that high with todays power levels. As long as your arms and legs work, I dont see why you would have any problem with a manual.

That person you spoke with does not know anything about cars. You should not listen to that person any longer. If you want stick all you need to know is that in most cars an auto is fastest at the track. Also at 650whp and a hard launch you should have the trans built.

I have 650rwhp in an M6 Turbo (T76) street car using a SPEC stage 4 and a SPEC billett steel flywheel. The clutch always holds, even with 5K+ clutch dumps on Nitto DRs. I will get M/T ET drags this season since right now, it either bogs or spins. I've been using this type clutch since 2003. This is my second one and it has been in there for over a year. Like everyone mentions, the autos are best for the dragstrip in a turbo application but even then, if you're going to get any boost off the line at all, you need a high stall TC and a 2 step to take full advantage. I have a built TH350 that I swap with my T56 every now and then. It makes zero PSI just footbraking it with the 2800 stall Vigilante. Calling Precision Industries about this and describing my application they said I needed 'at least' a 3800 stall. For street driving and freeway charging those pesky turbo imports, I love the T56 and I think you will too.

650hp is nothing to snub your nose at. Imo, anything 500hp+ at the tire is impressive.

Like tech member "I8URFORD" would say. There are 3 types of fast in a car..

1."wow, this thing is fast"
2."HOO-LEEEEE SSHHIIITTT"
3". OK, LET ME THE **** OUT!"
