2018-2019 10r80 boost by gear with turbo

[Peedystablo82]

Hey guys 2019 Mustang GT with Whipple here. Building a motor so I can up power to about 1300whp or so. Somebody was asking me why don't I just go turbo and I had another one of my friends with a 2018 Mustang GT with 1532whp twin turbos and ended up selling his car because the power was not manageable. He told me "there isn’t a input for trans signal on a 10r to tap into for boost by gear".

How true is this? You can't manage boost on a turbo on these 10r80s? Any helpful info would be greatly appreciated.

I’m manual and my boost by gear works off the output shaft speed and rpm. I think the 10r80 also has an output shaft speed sensor so you could do boost by gear as well.

I wouldn't worry about that as the 10R80 won't hold the power you are trying to make.

Yeah I'm literally getting my car back Friday with new clutches and circle d. I have heard I need to go th400 though.

I just finished putting my car together with a sleeved motor and I added more frictions to the 10R80, at 15 psi which is over 1000 whp I can spin the 305 45 17 ET STREET R @ 120 mph. Be careful at 1300 whp you will most likely crash that car on the street.

i have my 17 at limitless in Houston getting turbo’d and 6r80 swapped.....they see no issues with getting 1500rwhp with billet internals, clutch packs and circle d converter?

they have 2018’s running 8.01’s daily driven on 10r80’s. They actually talked me out of a glide swap and stick witht he 6r80

I can hook from 60 mph with about your power and the same tire so I think you have something wrong with your suspension.

Yeah I know what the power I have now, I can definitely hook from a 50 and 60 as long as it's not ice cold weather LOL.

The 6R80 is proven however the forward planetary is the weak link, once you do a billet planetary or a 4R200 hub it's pretty much bulletproof. The clutch packs in the 6R80 have more surface area than the 10R80, I put money on it that the 2018's running 8.01 on a 10R80 are smoking those clutches and have those transmissions out more than they care to tell you. I smoked the Mc Leod ones at 900 whp.

I just got the car back together and I changed from 62mm turbo's with a .82 AR to 67mm with 1.06 AR, when they light around 6000 rpm they come in hard and it spins the tires. My suspension hasn't changed from when I could hook 900 plus whp, I have all the suspension parts you can get and the tires are at 15 psi cold. The streets are still cold out here at around 50 deg F so not warm enough yet to put the power down.

Why in the world did you loosen up the a/r so much?

On the stock valve springs I was getting valve float with anything over 12 psi, when I built the motor I changed the springs and since I was buying new turbo's I didn't want to take any chances with backpressure issues.

What size turbine is it?

67mm the only step up from .82 AR is 1.06 in a Comp turbo, it's also worth noting that these are a T3 flange so the bigger AR is not as large as it sounds.

Well you had said 62mm to 67mm, I figured that was in reference to the compressor housing.

And, yes a t3 flange is a huge restriction vs t4 open. Makes more sense now.
