In the Stick Shift class. Gotta level the playing field somehow, you know.

Last time I raced a stick was 1984. Buick 3.8 V6 in a '76 Vega, T50, 105 HP, all stock except headers, ran 17's. Now, LS1/T56, all stock except headers, about 3x the power (although that is dropped a little by being at altitude vs. the 1500' that the Vega ran). Never put the Vega on the scales, but Berlinetta #2 weighed 3455 with me and a full tank of gas Sunday when I took it out for T&T.

6 passes, ran 13.6's at 103-ish (that's ~12.6's/111 at sea level). As I get used to it, figure out how to launch and hit all the gears (I was about 14-4 on the hitting-the-next-gear part Sunday), perhaps we'll settle down and make some noise in the class.

Since I'll also be running the '57, and running both whenever I'm running the Camaro, the most important thing will be remembering which car I'm in. . .

Yea, i wish i had the time to want to go to the 1/4 to see where my ca is, it doesnt like the 1/4 launching at 5100 RPM but it comes to life on the big end so it makes for a blast on the street but the car doesnt 60 foot like i wish with the damn Trex cam killing all the low end TQ it needs to get out of the hole like a T56 trans and 4.30 gears should.

Pass #9, Race #1 (the first 8 passes were during test & tunes the week prior):

I need to do some basic maintenance on my 2005 GTO and take it to the track. Its a manual transmission based car. My third gen is a manual as well but the 3rd to 4th synchro is going. It was originally an LB9/T5 car and now it has an 350 and the stock T5 behind it. Obviously I'll have to do something about that before racing it.

lol, that was predictable! looks like you got out without too much damage...thank goodness for loops. i'm thinking of a second loop in my car back by the rearend yoke. did it hurt the torque arm? sure hate that it put you on the trailer before eliminations started though did you have any of the other cars there?

five7kid

What torque arm?



I had the '57 out for my "regular" classes. Got rained out after two rounds, I was 3-1 (gave back the stripe for the "1").

Thats exactly what I was running, 12.6 at 111. I was leaving off idle cause I'm running nittos, looks like your having no problem hooking up, what gear are you running?

EDIT: 4.11 just saw that

five7kid

iTrader: (14)

Funny, nobody did (and I did ask).

Plunk, 4.10's, actually.

if you're running that type of suspension setup, what are you running for a rear? surely you didn't spend the fab time on that for a 7.5?

five7kid

iTrader: (14)

"Fab time" involved installing 4 bolts and welding on 4 tabs.

RS Chris

Your never gonna win like that. You need a one piece driveshaft.

So that setup replaces the torque arm with those short adjustable bars? Does that setup have a name?

five7kid

iTrader: (14)

New one-piece driveshaft being fabricated.

G-Force Suspension f-body ladderbar conversion. He only advertised it for 4th gens, I took a chance and tried them out.

i want a picture to see how well it works...

five7kid

iTrader: (14)

What would that pic look like?

mw66nova

iTrader: (13)

sorry, i'm doing chemistry lab reports right now too, lol. i should have been a little more specific. i'd like to see a picture of the car launching to see how well the tires are planted. this type of setup would allow my 8.5" 10bolt pipe dream to be a reality...and would allow me to go back to a torque arm if i so choose

mod313

That set up is similar to the Pete-Z setup that ATE race cars makes. Though it still uses the torque arm for travel limit during braking.
Looking at your pictures, I'd recommend relocating the fuel line & filter to get the line out of the driveshaft tunnel.

Next race is May 22nd. I may get it out to another test & tune before that, but track prep is notoriously poor for those T&T's.

five7kid

iTrader: (14)

That's the stock routing. I considered running it up by the subframe connector, but ended up doing this.

mod313

I remember mine having that same routing when it was stock. I moved it to the subframe connectors when I started really modifying the car. Without the torque arm to shield it, the line just looks too exposed to another shaft failure if the break happened closer to your loop.

five7kid

iTrader: (14)

Next time the exhaust will be there to shield it.

Next time it's at the track that is. Not the next time I break a driveshaft. . .

RS Chris

Would that setup work on a street/strip car, or is mainly for track use?

DIGGLER

iTrader: (1)

that setup works ok for a low power car, but once you start making power it will quickly start hitting the tires too hard. its just a ladder bar setup, really, but its much shorter than a correctly sized ladderbar setup.
i would stick with the torque arm setup.

five7kid

I haven't driven it except at the track. It seems to ride and handle fine, but admittedly that isn't a very thorough test.

G-Force claims a smoother, quieter ride. Since I've got open headers right now, I can't say about the quieter ride. When I got the car, the rear shocks were bad (even though they appeared to be new), I've replaced them now and it seems much better. But, I won't really know until I get the exhaust finished (next week).

This isn't intended to be a big-power strip-only car. At the time (over 2 years ago), I didn't see a better choice to allow good exhaust routing without custom fabrication. Perhaps it was a hasty choice, but time will tell. I could go back to a torque arm set-up if necessary.

radical82

Oh well, maybe you got the parts breakage thing out of your system for the season, five 7??? We went to Thunder Valley Sunday for a test and tune, freshened the engine this winter but that's it. Already did the run-in on the dyno. Ran a 9.80 just to shake it down, then did the throttle stop thing and back to the 9.90's, second pass went 9.90 with a 2, then a 5, then a 1!!!! Think we're ready! That was with the Brand X car... My '82 got sidelined to finish up a customer car that came from another shop where things were totally messed up on it, so I get to redo everything!!! Doesn't look like the 'maro will make the track anytime soon, but it's still gonna be a 5 speed car!!! Can't stand the thought of being "shiftless" anymore, going back to my Super Stock days and bangin' them gears!!!!!

Shagwell

I've talked about this system a few times on here. Really not a good set-up. - w/o trying to come off as an "attack" towards anyone in this thread, I'll point out some key issues.

It's an extremely short ladder bar set-up with a non-adjustable instant center. It has all the negatives of a full ladder bar system, but basically none of the positives. - The biggest issue being body roll. Any body roll with ladder bars is forcing the rear housing and/or chassis brackets to twist/bend/deflect. How long do you think the stock stamped tin is going to handle being well over stressed before it gives? It's just like bending a paperclip back and forth. Now you add in the extremely short/non-adjustable IC as Diggler noted, and you have a very poor system over-all.

A proper tq arm set-up will work considerably better.


I went high 1.8 60fts stock with crap-tastic 255/50 Kumhos with the auto. Built the car, went to the stick, and 315/35 nitto dr's; knocked out consistent 1.66-1.69 60fts. Then there's class cars like Will Stevenson and Troy Pirez who knock out 1.1x 60's all day on radials. Why screw with a good thing?

five7kid

For better or worse, that's already been stated.

FWIW, the 10-bolt ain't gonna cut-it. Case spread killed the gears. Predictable, I suppose, but not necessarily a given.

9" in the plans. The exhaust is half installed (long story - shop's bender went down for a week), so maybe I'll reconsider going back to a TA. Would make exhaust routing more difficult, already modified the driveshaft loop for better exhaust clearance. Maybe a shorter TA.

Or, continue down the G-Force path.

We'll see.

BTW, rode and handled just fine for the short time I did drive it on the street.

G-Force Suspension appears to be defunct. Website dead, phone disconnected. Oh, well.

Have the 9" center section (Strange case, True Trac carrier, Daytona pinion support, Richmond 4.11's, 1350 yoke), 31 spline Moser axles w/bearings and flanges (1/2" studs), LCARBs, sway bar mounts. Waiting for housing to arrive. In the meantime, remove the 10-bolt, fab new tabs for the ladder bar link attach.
