Breaking 3550's?
 

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

Re: Breaking 3550's?
 

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

Re: Breaking 3550's?
 

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. :rolleyes:

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.

as have i...it's all part of being lucky at times..eventually everything will break

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.
