Hey, chuggin' along. Just finished a big overhaul on my turbo build after 12yrs.

@  Nateteo : (12 April 2021 - 05:56 PM)

literally, the last time I logged in was 3 years ago hows everybody doing

@  dezldave961 : (12 April 2021 - 04:43 PM)

Ya, they do open bracket at GS Nationals. I may go if I'm free, just to attend, even if there's no cage, yet.

@  Marchi1 : (12 April 2021 - 01:32 PM)

I am taking the SC car.I am sure it is a big event as it is in Bowling Green, KY so yeah will need to be fully copliant, but I think there is a bracket class. God I hope so

@  dezldave961 : (08 April 2021 - 01:50 PM)

*S&W Racecars cage for 95-99 Monte... I'd actually fit the xTSM class, aside from not being a RWD, if I swapped the Air-Air I/C back in. Probably wouldn't be competitive just yet, but I'd like to see them squirm.

@  dezldave961 : (08 April 2021 - 01:48 PM)

My only hesitation is that it's a big "gate-keeper" club, from my year of monitoring their forum. I might show up for fun to T&T in an open class, if I have a cage by then (S&S 90's W-body one when I get time).

@  dezldave961 : (07 April 2021 - 08:12 PM)

Oh, is the TurboBuick thing om, again? That's what I initially started my build overhaul for last year. Might be able to get out there, finally.

@  Marchi1 : (07 April 2021 - 02:53 PM)

Dave there is a Buick only event in May in Bowling Green...

@  dezldave961 : (04 April 2021 - 02:51 PM)

For launching in street trim with a s/c, you can pre-load just a bit at staging, then roll from that point to full throttle over ~1-2sec as traction permits. The tires will screech some at a track, but a 1.9-2.1 is the good typical range for most folks, with occasional freaks getting 1.8-1.9 success (my best on 2nd-hand Nitto 555R's was maybe mid-1.9's with my GenV/2.7/XP/3.29 setup at Norwalk).

@  dezldave961 : (03 April 2021 - 06:11 PM)

You should be able to modulate the throttle a bit better to get at least a 2.0 with practice. The Mustang is probably about all that can get, they're not too impressive without work.

@  ejguillot : (02 April 2021 - 01:12 PM)

I wasn't the only one having problems launching, There was a 2015 Mustang 5.0 on drag radials whose best time was a 12.9 after 3 tries or so.

@  ejguillot : (02 April 2021 - 01:09 PM)

Good news was nothing broke, and no KR on a 2.8" pulley. Will be revising timing tables too.

@  ejguillot : (02 April 2021 - 01:08 PM)

The first runs were so so. 13.5@104, couldn't launch for shit! 2.4 60' was the best I got. Then I look things over and realize my front shocks are all worn out. Ordered some KYB's from Rockauto on sale ($70 shipped), will be installing those and see what I can do next time.

@  dezldave961 : (01 April 2021 - 11:38 AM)

Cool. I may try BMP eventually, based on prep shown in Cleetus videos. Might live in the area again soon, too.

@  Marchi1 : (25 March 2021 - 03:11 PM)

The silver car will be hitting the track in May...Should see better numbers than the last pass 6 years ago

@  Marchi1 : (25 March 2021 - 03:11 PM)

Waiting for numbers.....

@  ejguillot : (25 March 2021 - 01:47 PM)

Hi all, finally taking my project GS to Bradenton Motorsports Park for it's maiden 1/4 mile run.

@  dezldave961 : (22 March 2021 - 01:21 PM)

Ya... I'm having fun working on mine, but mostly going to hit events for all cars. The big 3800 ones from ClubGP days are gone, aside from one in Detroit.

Way back when, we got the GMPP kit and it included sway bars and trailing arms and strut tower brace for cheap, see pic below.  I think it came from rock auto but now it does not include the rear trailing arms and the STB for the rear is the same as the front and in the kit and you simply order a duplicate.  Perhaps someone will chime in with the part numbers from GMP Direct.  The Don Rome brackets are a must IMHO.

If memory serves me right SLP had the largest diameter rear sway bar. If you're thinking about upgrading I'd go for it.

Thanks guys, anyone know if the end links and bushing that come with the set are any good? For example I read posts about the gmpp bars that say toss the hardware that comes with them for Moog or don't bother at all, just want wondering it slp's supplied hardware is adequate?

All are upgrades so all are good IMHO.  The GMPP stuff is great and has been in the car for several years and works/feels just great.  It's when you start going to replace parts in the 'upgrades' then that tends to stiffen everything up like a Grand Prix.  Depends what you're looking for.

Interesting point loly, so SLP could be too much of a good thing for a Buick? Not familiar with the ride quality of a grand Prix??

Also if I went with gmpp bars, could someone please list the part numbers for the Moog end links and bushings to use with them?

As said, the end links and bushings that come with the GMPP Kit are just fine, no need for Moog anything really.  The GMPP Kit is what they put on Police Impala vehicles.... good enough.  The Moog hardware is going to be of a different material IIRC.... hence, a much stiffer ride,  Solid ride vs Stiff ride - pick one.  Others chyme in here please, especially if you exchanged the end links, etc for a stiffer material than OEM for Buick.

The poly bushings definitely firm things up. My old '00 was setup that way. Gmpp f&r bars with energy suspension poly bushings anywhere I could and the moog endlinks. Handling was amazing on the agx/ssc combo but you definitely forgot it was a buick with a much more harsh ride as a result. Just depends on what you're after.

Lol. Yep. Just picked up an 07 grand prix GT (L32) and need to order up some suspension and misc for it and just catching up. Figured I'd check here first to see if anything was available.

I got over the harshness, when you can at least sorta hang with an sti it's worth it.

Hey Kent. I do have a couple of stbs sitting around that are in good shape...let me know just want to get them out of the garage.

 

As for replacement bars a dorman bar is solid for the front and will fix most issues, and can also be had for a little cheaper. Someone said they found a larger rear bar, but I don't remember where.

 

Personally a larger rear bar will be a more neutral feel on the car versus going big front and bog rear. All a matter of what you want in your car.

I preferred the Poly bushings for the mounts ft and rear. But used the Rubber bar links on the front that came with the GMPP bars. kept the lean to a minimum without being harsh.

3800performance was a guy drop-shipping from the Detroit suburbs years back, but faded away (a couple Motor City ClubGP guys used to go directly to him, but that was 10+yrs ago).  SLP quit on our market in ~2003, so anything left from them is scattered among the crowd.

 

ZZP and Intense (to a fading degree) are the only major 3800/Wbody-specific vendors remaining... Milzy is out there, too, but I haven't looked into his operation aside from some conflicting feedback.

 

You can either go to them, or seek what you need from innovative/resourceful places, such as re-purposing things from other engines/platforms or items from cars like Police Impalas or GP GXP's, etc.  We're in a semi-drought for performance options besides the main things left available, and it may stay that way for a while, unless people heavily return to this platform (probably just engine) for use in custom projects.

It does seem like ZZP is the big player left, with Intense being a not so interested 2nd player.  I've looked at Milzy's site, but the pricing is rather high compared to everyone else.

Ya, a friend in FL was able to get some Intense parts this summer, but it seems like John R. isn't putting much into it anymore (bought it from Scott C. 5+yrs back).  Sad, because ZZP has shown they're willing to continue pushing the platform (Zoom's stroker M90 build, new Stg 2.5 I/C and Bosch pump modification), but that won't continue for long if there's not a strong market to make them earn it.  I know they're hunting for the next platform to battle for, since the smaller GM 4cyl stuff isn't as passionate/long-term as 3800's always have been.

Add to that the fact that GM keeps moving away from cars/sedans to trucks/crossovers, and there aren't that many car sales being made. So a smaller pool of cars to mod.
