How much is too much powah

In my bus there is a spicer 5 speed manual transmission that is rated for 180hp and 430 flbtq.
Driving it is a t444e making 175hp and 460(peak) flbtq.

I want to retune this turd.
210hp would be nice, 195 would be too.

How far past the ratings of the trans do you think I can go without incurring serious damages.
I don't normally thrash my equipment, I'm not trying to do burnouts..... I just want to be able to accelerate!

You won't have a issue.

Go for it.

My engine's tuned to 190hp (t444E) and has no problem accelerating. I concur with Nat

A Spicer manual can probably handle twice the HP & torque. My main concern would be the clutch. Might be able to beef it up a bit via springs and such but I will leave that for more knowledgeable minds.

It's not like it doesn't, it just thinks it's a drugged sloth.
It acts like the VW golf we put 3000 lbs behind..... You get the picture :P

As long as your not slipping your clutch, you will be fine.

Where are you guys going for tunes? Need one for my T444E also. I have heard anything for a 7.3 Powerstroke will work but want to get a first hand view on that.

The local rural IH dealer said he would do it for me.
He is an old farmer type..... Just think "now that there sound like a idear, eh...."

I think I'd trust a farmer to come up with a good solid fix before I would an engineer.
