Throwing some hp through a Getrag????
 

I was wanting to get yalls opinon on how much hp i should feel comprtable with running through my getrag. I am going to start a full motor rebuld in january and wanting to put as much horse power though that getrag that i can.... I have just finished rebuilding it with new input shaft, 3rd gear, sleeves, syncros, bearings nearly everything... and running lucas 75w-90 full synthetic in it, with a valair 650 clutch, rest of the drive train is stock. I am just wondering whats a semi-safe hp rating to shoot for at the flywheel. My inital goal was 550 at the wheels, but Im thinking 400 at the flywheel will be the most I can go with out having to get the nv4500.... reason for keeping the getrag is I want to try and keep it close to original its being fully restored, just needs some balls. all input is appreciated! thanks

Not much horse power should be expected, cause the G-Rag was not designed to handle much torque at all, IMO, get a NV4500 or a NV5600 if you want one to last longer and upgrade a NV4500 or a NV5600. IMO. :rock:

I don't believe the Getrag was designed to handle anything above stock horsepower or torque. :rock:

I called alligator performance and they said 400 at flywheel should be my max.... but ive heard of ppl running more than that is why im asking, also the getrag spec for oil is 5w-30 but not filled enough, this causes to much heat without the right amount of oil for it to dissipate in, and eventually causes tranny failure, so you either overfill it by a quart.

I have heard they called it a Getrag 360 because it was only designed to handle 360 Ft. Lbs. of torque. That's it.

What you do past that, including me and it holds together is luckiness and that's it.

From the factory these motors come with 400ft torque, is thats true they were destin for failure, dodge dont always do things right but that sounds a little fishy....... Like the stock vp-44 requires 96 or 99 gph but the lift pumps were only 50gph. which is why they failed to

That's why I stated that's what I heard, I don't actually know the truth, but it is possible.

I sold my 93' to guy who built it to 438hp at the rear tires. he drove it for about a year with the getrag when he made a sudden 5th to 3rd downshift and smoked it. he then upgraded to an nv4500. that getrag wasnt babied they will take more than people think.

When I get to 500 to 600 HP I intend on finding out how much punishment they will take, LOL, when I get my NV5600 for install ready. :rock:

Im running upwards of 300hp on mine. but get rid of that gear oil n go to 5l of 5w30 synthetic. But yes there rated for 360ld/ft of torque

Stomp puts out 644hp through his getrag on fuel only, 899hp on nitrous and water meth. Built right it can handle some power.
