Transmission / Overdrive: T10 HP rating

[what huh]

I keep going back and forth with utilizing the T10 set up I have in my Lark. The plan right now is to buy another engine, mate the t10 to it leaving the Lark untouched and driving while I do all the wrenching in the background. I play around with power upgrades as well which brings me to the question....

What are the factory ratings on a T10?

FWIW, the T10 was used behind Ford big blocks with 400 lbs/ft of torque. What are you planning to build?

Thats good to hear. Im not planning on building anything with big power. I just want to play around and do some research about some tweaks here and there. I am a boost guy at heart but if I go that route Im doing a very mild build. 5psi perhaps, just enough to keep good drivabilty and put the stupid smile on my face when I need it.

Funny how horsepower rating also has much to do on the driver. You hear of stories of guys saying that there T10 has held up to 600-700 Hp and they may very well have that but they only ever baby their car to the car show. Then there is the guy who says he broke it with 250 hp but doesnt say that he is launching at 3500rpms on slicks on a prepped track.

For the record Jack, thank you for your contribution to the Studebaker/Packer Community

Since turbo boost does not make big low end torque, the T10 would probably handle it easily

For true. Ted Harbit can give us more data points, as his Stude Tomato launched 300hp @ 3500 for years before a T10 finally broke.

Thanks for the kind words. The Studebaker-Packard community are a great bunch and we all do what we can.

The T10 in my 62 Daytona 289 turbo has stood up to 18+ lbs boost for years without problems. clutches and head gaskets are another issue! I don't race and I do have a silly grin, especially in stop and go traffic. enjoy Luck Doofus

Wow 18lbs, what have you done to the motor to handle that? Or is it so much that it would need its own thread?

The T10 was also used with Pontiac 421 which were pretty healthy back in the early 1960's

Wasn't Dick Datson able to get something like 21 lbs of boost into a Stude engine? That's what my addled memory tells me anyways.

Except the NASCAR Pontiacs would usually end up blowing third gear out on road courses like Riverside, CA.
But...heavy cars, high compression engines, and lots of downshifting with the corners.

One way of looking at manifold pressure is boost is a measure of work done to compress air which couldn't get into the cylinder. It would be possible to produce and measure 40 PSI of boost in a Studebaker intake manifold, but gauge pressure is not the goal. Flow makes horsepower. Best cylinder head porting, best intake manifold, ideal cam timing, would make more horsepower at 20 PSI than a stopped-up system at 40 PSI, because more air/fuel got into the cylinder instead of just being super-heated in a high pressure intake manifold.

FWIW, the racing diesels produce 100 PSI of manifold pressure and there are not blocks and head studs strong enough to contain that when then compressed to 1600 PSI. They run insanely strong until they grenade.

Well with my goals being single digits I guess I’ll be in good shape lol along with some tips that doofus gave me

But no matter the PSI ... proper tuning should never be over looked
