Breaking 3550's?

[SteedaChaos]

Well when i got the blower installed and tuned the other day, i knew i'd be putting out above the capacity of my 2 old style 3550's but didn't know the combo would hit as high as it did at 430rwhp, 454rwtq w/ clutch slip. going back later w/ a meth. kit and get back that 450-60rwhp she put out on a leaner A/F (11.1ish atm) w/ 470-500rwtq.

I'm pretty sure w/ hard launches on a holding clutch i'll eventually break the 10-spline in-put shaft. Really curious though has anyone heard/seen/experienced the 3550's just flat-out breaking on the hwy like T-5's are notorious for? W/ my out-put curious if i'll experience blowing 3rd/4th/5th gears like i have w/ the T-5's.

It will be more resillient than a T5. I've heard some pretty good feedback on the 3550. It's robust. Hard-hooking clutch and tires will hurt it eventually though.

Yea possibly the gears theirselves are extremely strong, and the only real weak link is the in-put shaft itself. W/ the T-5's i've blown 5th(2x) 4th(2x) and 3rd(1x), just pondering if out on the open roads wringing her out if i'll blow the 3550's gears.

Yea you will explode that lil 10spline in a heart beat.... Get a 26 spline tranny

Yea i'm aware of the in-put shaft. Of all these years since the mid 90's of knowing the 3550's, something that i've not heard of is someone blowing the GEARS . I'm curious an interested in hearing about blown gears and the story behind the results.

This old #1 3550 i'll keep as is, i'll convert my #2 to 26-spline if deemed to be neccesary. My full-on drag racing (w/ slicks) will be very lil to non-existent after this week-end. I'll just enjoy street-trim racing and 5th gear top-end runs.

been 6's in the 1/8th on a 10 spline 3550

Just because you have been there, doesn't mean it ain't going to break eventually. Hell, I've seen people go 6's with a T-5 too.

Personally i have not seen or heard of but one broke, A kid at Blue mountain tried to leave with wrinkle walls and 200 spray with the motor on the rev box. Snapped the OUTPUT shaft no other damage i saw. Only one of our cars has the 3550 but has had no problems as of yet.

Wow popped the OUT-put shaft that's brutal there. The first time i broke open me #1 3550 to freshen it up i was impressed and gleeful w/ the size of the main/out-put shaft.
