BadAss SRT-Z - 2.4L / A568 - Update!!!

[BadAssPerformance]

It sucks that you went through the whole tranny only to have the same noise occur. Gonna just run it as is?

Thats the problem, I didnt go thru the whole trans, I saw the cracked bearing and plate and thought that HAD to be it trans is all apart again and pretty sure its the front intermediate shaft bearing and the OBX is possibly making noise too. Guess the hammering of axle snappage might have beat some parts up.

Between this and all the other stuff that needs to be checked out on the car and busy at work, I'm outta time, the car will not make it to drag week

MB and I are still planning on going tho to crew/spectate, etc. Unless they let me run a backup car?

That blows! Good luck!!

[Aries_Turbo]

is the front bearing the tig glued one or the one with the snap ring at the other end?

take the csx clone?

Front is TIG glued (think "front" of engine)

Clone has cracked head (cracks from coolant triangles to each cylinder ) ... I'd race it on any track, but heats up on highway :/

when i think of a RWD car, front and rear are obvious. on our cars, i think it terms of passenger side and drivers side.

that sucks, we gotta figure out a cup and cone setup for that intermediate shaft somehow.

Straight cut gears...

I think it would be best to ditch the entire aluminum bearing plate and retaining plate and replace that with 1 piece of steel (heavy maybe to save on machining costs). Just requires mapping out the fastener and bearing locations on paper then putting that into a CAD program. At that point we would then figure out bearings that would be able to fit into the plate and then design the bearing hole sizes for the plate. I was thinking about this on the way home from work. I just don't have time for this project at the moment (more pressing automotive issues). Then find a narrow tapered bearing that can fit into that thickness. I really don't see how the other stuff is hard because we should be able to make various thickness inner and outer sleeves to make tapered bearings fit everywhere else (the front side). No need for a perfect fit. Sleeves are not a big deal to make.

Update...

Replaced the front I-shaft bearing and put a different 3-4 fork/rail in it. Seems to shift OK, still makes some gear whine tho

Took it to Grove yesterday anyways... back on 110... Went 10.80 @ 136 off the trailer, came back with a high idle (vacuum/boost leak), ran 10.86 at 133... so probably losing boost, need to fix!

[85glht]

Back on 110...... 110 octane fuel?

[Ondonti]

60' ? How would you rate the pass? tractionless and sad or decent and fun?

Yes, I had started tuning it on 93 for Drag Week, but since that didn't happen... back to the good stuff!

IIR for 60' the first pass was 1.76 and the second was 1.71, spinning all the way thru 1st, so pretty much tractionless, but still fun runs LOL

Ok, I see.

Your 10.56 run was only 1.70 and the people around you on the list are no better then 1.69.

I would be interested to see how limiting power in 1st gear could improve 60's until you got to the point at your cars weight where you started going slower. That or at least make your runs more consistent. My best 60' ever was only a 13 second pass running through a slipping clutch. 1.71. I would assume that Pat goes so deep into the ranks with good shifting but also good 60's because his HP/weight is lower then everyone else around him. Turbo-Mopar times does not show most of us doing very well at the 60' and 1.6' seem to be mostly only 10 second territory.

Man let me know next time your going to the Grove. I would love to see you run. Hell mite even bring my Shelby down.

Yep... get out of my head! LOL... the track was laaaaaazy and didn't get going for a looooong time, seriously musta had a problem cuz the lanes opened 2hr late. Was planning to make a pass or two on low boost, but after the delay just decided to turn it up off the trailer. I have a ghetto 2-stage boost controller I made a couple years ago but didn't have time to install it before going

Good thoughts on 60' but the difference is after that... the 10.56 was on 26's, now its back on 24.5's. Similar 60', but (I need to look up to confirm) the 26's net a better 330'

Another difference in the runs, the 10.56 was more granny shifting, the runs from last weekend were closer to open throttle.... so need to investigate the 330' and boost leakage...

Will do! I usually try to post when we're going in the SDAC-Chicagoland Chapter lounge thread here, and in the SDAC Chicago group on FaceBook, also on the SDAC-CL e-mail list. Hoping to get the Z out at least one more time this year!

TW, we're going to grove tonight, but with DodgeShadowChik's Talon

I was figuring you got out of 1st gear just after the 60' and you didn't say anything about 2nd spinning. Of course I know there is spinning hard and then there is that tire slipping roar that could be what is hurting the 330'. I sorta assumed that doesn't hurt much because it acts like a loose torque converter but I could be very wrong.

Part of his 330 drop is going to be due to speed at shifts. Given the same gearing with a shorter tire, the car is going to be traveling slower every time he gets off the power to shift. Even for only a split second, the if the car is rolling (not accelerating) slower, it's going to have an effect on ET at every step through the run.

On my drag week car, I countered this a bit by going to a 3.50 gear with the shorter slicks. Given the same individual gear gearing and a 6750 shift rpm (just to keep it even), but one combo being 3.50 gear/23" and one being 3.85 gear/24.5, I'm going 2 mph faster on the 1/2 shift, 2.5 mph faster on the 2/3 shift and 3.2 mph faster on the 3/4 shift. This further helps it ET better for a given 1/4 mile trap speed.

For JT, with a 6750 shift rpm and the same trans/gearing, but going to 24.5" slicks from the 26's, he is going 2.2 mph slower on the 1/2, 3.4 mph slower on the 2/3 and 5.2 mph slower on the 3/4.

If you're only rolling, you want to be rolling as fast as possible. :-)

Can his 330' could seem exaggeratedly worse if that rolling time is right before the 330'? Post up full slips to compare JT! Wondering if this car will get enough passes to see if axles survive with current driving habits and setup.

Yep..if he's shifting after the 330 on the 26's but before the 330 on 24.5's, that would be seen heavily in the 330 ET. It's a perfect example of speed traveling during the shift and how it effects ET.

[BadAssPerformance]

if you're spinning, you're not pulling as hard. 24.5's spun all the way thru 1st and I held it in 1st till the wheel speed caught up to the rpm so it didn't drop rpm and bog in 2nd, I think this is where some of the lost ET is

After abusing the tires in 1st I think it hooked ok in 2nd, maybe not at first, but once it was pulling. I'll have to dig up time slips to compare
