@turbobird would love to see some pics of your car.

I got the car out last month first time ever, went 12.4 and on my 4th pass went 9.30s. Later went 6.04@123 in the 1/8 maybe a high 9.2x pass.

I am redoing some of the front suspension for next season to rid the car of the current death wobble at high speeds.

This is my turbo charged bird pretty much locked myself in the garage w my buddy Chris for 48 hrs built the whole set up w the goal of running 9s and went 10.00 right off the trailer . That was carberator and no. Inter-cooled w water meth and a diesel turbo.
I sized the turbo this way.
455 cid x 6000rpm is the same air flow as 900cid and 3000 rpm !
Bingo Detroit diesel turbo works!
Everyone said it wouldn’t even make it down the track. I did a forum on a Pontiac site teaching guys how to build it and I had guys in New Zealand. Iceland , Australia all over the place w my basic designed set up on theirs cars. Put it together last long block version in about late 2005 and changed it up top to fuel injection- Intercooler and a ceramic ball bearing turbo - right before the HPP race at englishtown 2009 (which I won BTW ) it’s still together running without even a spark plug change. Still has gen 7 DFI on it and one of Jason betwardas old turbos I got from a buddy who worked at turbo people . Which I’m proud To own jason was the best of the best!

Car is set up at 11 psi and clicks off 9.70 at 146 off the foot brake. On 93 octane .

Every nut bolt weld even the paint on this car that GM didn’t put there I put there w my own two hands . No one worked on this car not one piece was subbed out
Or bought complete. Welded the cage, narrowed the rear , did the body I even made the original set of headers for it myself from a couple sets of 3 tubes I had kicking around . I later copied them in stainless.

Very cool! Ladder bar right? Diag track locator?

My 2024 goal is 8.50/5.40. Once it runs that I'll fix up the exterior, has to earn it.

I street drive the car all summer.

Yeah I’m ladder bar and diagonal link. I’d prefer a watts or a pan hard bar personally especially for street use the diagonal link will bind like carzy on the street I’ve snapped mine twice just plain beat it to death on the street.

Doesn’t look like it but had nasty tire shake on this burnout on the street and snapped it right after. .

https://youtu.be/AbYnvJggx_o?si=DwDW-ASOjWMhODPN
(Idk what my kids saying in this one she’s really little) but I snapped the diagonal link on this run
It’s a spring rate issue as the Moroso truck springs settled differently it hits the bump stops differently and violently when I lift and this causes a dynamic waddle that loads and unloads the already beat up diagonal link.
It just needs to be fixed but there’s always 47 more important things on the list ahead of it.

I keep an eye on my diag bar.

I talked to a buddy about a panhard bar and a watts link setup.

Lately my buddies are all about running a wishbone.

Here’s another

From long ago the kids you hear in this video are 18 now lol.

https://youtu.be/Yj0Ge3GQbaI?si=UqG0Vw537QVA27Gb

They were probably 3 or 4 I’d guess when this was taken. Took me a while to post them on YT. So they are older than 10 years

I looked at the wishbone and was told it would have the same tendencies as the diagonal link.

I also can’t stand where my shocks are located because I can’t run the stock tank location . I street the car more than anything these days so I prefer a large tank w a sending unit. IDK what I’ll do w that rear suspension in the future . It’s one of those things where if I’m gonna do surgery to it I would probably go from the 12 bolt to a fab nine, if Im gonna do that maybe go to a diagonal 4 link for the street , if I’m gonna do that go back to a regular tank location . And it just keeps going and going. Where does it end. In the mean tie I’ve been racing the Tesla 😂

I check my diagonal link all the time because the car sits up on the lift most of its time . I never found any indication it was fatigued before I snapped the end links .

You broke the rod or a heim?

I think if at some point I'm having work done on the back, like changing out the front brackets so I can change the anti-squat, I'd look into thicker diameter diag bar though the one I got came from Chris Alston. I just now there is thicker diameter options I could get customized.

I kicked around changing this car back to leafs but after talking to some friends with quicker leaf spring 1st gens I think it's a step back. Ladder bars are working really well right now though Tin Soldier's 4 link setup looks good too.

I think the issue folks have with wishbones is the slider binding up.
