Who makes one besides Liberty or is going to start making them?

 

hopefully soon there wont be a need for one

 

Something else will be available soon, keep an eye out

 

I believe PPG is working on one.

 

There are going to at least 4 options within the next few months, that I've been told of

 

why do you say that?

 

PPG's design of the gearset will supposedly ease the stress on the bell housing and lower the failure rate

and i know of one company that is also supposedly close to having their own billet bell housing prototype done and ready for testing, that may be available within the next month for the initial testing at least

(of course this is all hear say, word of mouth so far so take it all with a grain of salt until it is tested and proven)

 

yeah, don't really know ho that would be possible. if you brace the stock bell housing right, it will hold up

 

i haven't really studied the stock bellhousing in depth, but would it be possible to just machine away some material and then press in a newly machined piece made out of stronger material which would easily hold the shafts together without breaking?

we spend 500-1000 to sleeve blocks, would modifying the stock transmission bellhousing be a feasible idea as opposed to making a completely new bellhousing from scratch?

 

Mike you're kind of working with the same theory as a few others on here. Tony1 was using a braced/welded case and it seemed to work well for him. Not sure what's going to happen when he goes to the PPG gearset, but he might switch to the billet housing. PM him for some more theory

 

We were parked next to each other at the Ennis IFO and actually talked about that in person. If I recall, he was saying that the new gearset he was getting (PPG? I can't remember the name) would have something to keep the casing from being damaged. I was under the impression it would be something that is part of the shafts' assembly, but really didn't go into detail as we both had stuff to do.

It was exciting to see Tony make that 8.90 pass and also exciting that my buddy Kris made his first 9 second pass in the car we brought to the event. It seems like Tony has found the new "weak link" in his setup as his car gets even lower ET's. I can't wait to see what happens when the bellhousing is not an issue.

Maybe I should get a Mechanical Engineering Degree after I finish up my BS in Chemical Engineering next semester lol.

 

ive been having good luck with the last minute, unmodified 295,000 mile case that i pulled out of my old DD lol

the modified/braced/welded cases are still having issues. its interesting seeing who is having problems with which parts and comparing it to what their car does going down the track. i think thats why we are never going to find the perfectly engineered transmission. so many cars are so far away from being set up properly...or are set up differently for that matter.

just because a part works well for the fastest guys in the class that are making the most power doesnt mean its going to work the same for the guy who is trying to put his power down all wrong and shaking the tires and cruising on the rev limiter for the first 500ft.

 

LOL

 

Good call Joe, but at the same time. When these people are putting their setups together all wrong, and there's no one that can/will help or they can't afford to do it, is there a way that they can use a braced case to help? Or what about the guys that bought a liberty, and have NO idea that they need to be maintained? How many Liberty owners know that they are supposed to pull the trans out and maintain the stuff inside?

We're still a young sport, that can only now buy everything necessary to run the numbers, we still don't have a HUGE knowledge base of people that really know what they are doing, and can/will help people

 

dont get me wrong anything to make anything on the car stronger and more reliable im all for it.

the thing that has always made me a little nervous about the nice billet cases....is what happens when you break a final drive? does your $1000+ case just become a paper weight at that point? i guess its not much differnet than having a head ported and then popping a motor or dropping a valve or something.

ive had the transmission out of my car 6 times in the last month and a half. i also agree with you that people dont t realize how much work it is to maintain one of these cars like you just said clayton lol

 

Machining the housing and pressing something in would't be possible IMO. The countershaft bearing is already in there and that is the weak area. Not much room to bore it out to press a sleeve in there that the bearing would then go in. If you did, I think it would just weaken the case even more. When it comes down to it, no matter what you do to the OEM case, it is still cast aluminum. Bracing helps, but once you get your car to a certain point it might not be enough.

I think a lot of it just comes down the the variables for each case. Tony cracked his welded case on his last 8.9x pass. Tex isn't having a problem with his cases at 1,2xx whp hot rod. Right now there isn't enough info out there to 100% figure out a way to make the OEM cases work for every setup.

 

aww

 

My case in my old car lasted 80 plus passes before it got a small hair line crack. I just pulled the trans apart and drilled a hole thru the crack and filled the hole. The new cars case cracked in 13 passes but it also had a 1-2-3-2 shift on it. lol. You win some you lose some.

The only problem with welding the case is it can get warped and cause other issues.

 

ummm, okay

we have a welded up case that we destroyed -- first crack after about 10 passes -- not usable anymore after about 20 passes

like someone said, this is all still new and growing, it will take some time but the issues will eventually get figured out.

 

PPG is not making a billet housing, the gearsets will not need one, but we beleive they should work with a billet housing if somebody already has one and wants to run it.

 

Good point Erik.

I love how everyone knows something because of rumor's. lol

Who said anything about machining and pressing?

Not really. Tony has broken a few welded cases now to the best of my knowledge and I don't forsee him going to a different bellhousing. What does that really fix? Like someone else said Tex is on a pretty basic setup and he keeps his trans together after a long time of abuse. He must be doing something right.

If you brace the gearset correctly, instead of just the cuff method, then you limit stress in other spots as well. PPG is a very smart company, like some others, and will not settle for anything less that success. They will not tarnish their good name and reputation if they felt that this was a risk for the company.

 

1200 whp.

 

WOW lol

I'm sure he will even tell you it's not making that much...it should go 190 with that power

 

We have been running a Liberty tranny with the billet housing since the IFO race in Kansas City in late September of this year. It has been in the car for that race, the Tulsa IFO race, and Ennis IFO race. Also, many test n tune nights and on the dyno for tuning. As far as I know it is the most up to date setup that Liberty offers, as it was bought secondhand from another racer.

I will admit that we have not serviced it since we put it in nor have we had any issues with it whatsoever. Now that the season is over for us here, it will be pulled out and torn apart to see if anything needs to be addressed.

To date all we have done is put it in the car and fill it with Redline MT-90.

 

Yeah, lets be real, that car isn't making 1200whp.

The reality of it is that I wasn't breaking much last year running mid to low 9's on the 24.5" tire. This year i've cracked 2 cases and run consistent low 9's and high 8's on the 26" tire. I guess what i'm getting at is it doesn't make sense to compare results from cars that perform different.

If you want to compare to a Hot Rod car at that level, look at Chuck's car. He makes about 100-150 more hp than me, still less than 1200whp, and he breaks cases left and right.

If you're going fast, you're breaking the stock cases...
