Thanks guys
I am a little ways from getting the car
Lightened then I can weigh and measure things
I think a better bar the right size will help
along with the other things. Looks like you
have been fine tuning for a while

We initially thought going with the 0.250" wall tube bar was getting jiggy with it, Ron mentioned to me in passing the other day that an even bigger front bar than what is on the car now would still help it.

It's been a progression for sure, but just to be clear...the car has been neutral balanced ever since stage 1. It just keeps getting faster and faster the flatter we've gotten it to run.

Thanks for sharing! Curious, what do those front bars translate to in # rate?

What are you feeling most with the car as you make changes- faster times, easier to drive, less stress trying to keep the car in control, etc. ...? All of the above?

Right now sway bars are one of my focuses so while the car is down for some repairs and upgrades I'm taking notes. :)

Ever since we put Stage 1 of Ron's setup under this car, the car has been friendly to drive. I am not exaggerating...all of the evils the car had previously just went away.

From then on it has just been a matter of fine tuning and tweaking both shock settings and driver ability to get the car to carry maximum speed through the corners...which in turn led to faster times on the clock and higher rankings in the day's results.

Each subsequent upgrade in front bar (and rear springs) just made the car more responsive to steering input and gave it the ability to carry even more speed in all 3 phases of a turn.

We are at a point now with both driver ability and car setup that a single click on a shock or a single pound of air pressure will make a slight change one way or the other...whatever we need to carry just a bit more speed in a specific turn. There are no more large problem areas...it's all just minor tweaking to tune to a specific course...or driver preference.


At CAM East when Ryan was co-driving the car with me, his preference is a "tight" handling car. He likes to lean on the outside front tire the most, feel where it's grip level is at and drive up to that point...while I like more of a "free" feel (probably comes from driving a car that would not turn for so long).

We discussed this beforehand and also discussed where to start on the rear shock settings...knowing what it would be like and how we'd sneak up on tightening the rear rebound hopefully without going too far. We knew it would start off pretty free, and the opposite side would be once we tightened up the rear rebound too much it would start carrying the inside rear tire and upset the car that way. We adjusted 1 click into the rear shocks 1 after my first run, then 1 click after his first run...after his second run he wanted 1 more click and that got the car pretty good everywhere on the course.

By then he was putting laps in almost a second faster than me, in a car he had never driven before, with a setup like he had never driven before. After that, each of his runs were within 1 or 2 tenths of his best time. On his last run he asked me if we could lower the front tire pressures about 4 psi. He had his fast time in the books already and wanted to see if lowering the front pressures would tighten the car up enough for him to carry a bit more speed thru the large 180 at the back. His time was about the same as previous runs, he said it was a tick better in the large 180, but it felt lazier just about everywhere else on the course. On Sunday morning he didn't hesitate...we put the original tire pressures back in the car and we both set pretty fast times on our first runs that day as well.

My point for typing all of that is...I feel that anyone can adapt to driving this type of setup, it really is that easy to drive. You do not fight the car, you just have to coax it into finding the most speed you can with little tweaks here and there...both on the car and from the driver seat. The car has been like that ever since we had the F-body bar on the front...it's just a LOT faster now with the MonsterBar up under there.

So an old mechanical issue reared it's ugly head again at the SCCA Nationals. It took me a while to diagnose exactly what it was, it actually started at CAM East month or so ago. I initially thought it was the clutch posi giving up again as it seemed like the car was spinning the inside rear tire on exits from short sharper turns. The more I drove it and the more it happened, I finally figured out the clutch was slipping, not the diff.

If you listen close during these runs, on the exit of some corners you'll hear the RPMs spike up but the car doesn't move nor do the tires spin, that's the clutch slipping.



It hurt my times on the big long fast courses at Lincoln so I did not finish well in either event. The car cornered fantastic, much better than I thought it would...it just wouldn't handle down the fast straights. Time to come up with a new game plan. This clutch is a RAM rated at 500 hp I think that is just over a year old...and I'm making no where near that kind of power.

Lance sorry to hear the clutch was heading south on you
Not the best place if there really is one to start slipping

I have used a Centerforce clutch in both cars for many years
Firebird is 750hp at the flywheel but not a lot of time on the
new motor racing...Pantera 600 hp just got a new clutch after 10 years
of beating on the car... now I mostly track the car but smoked
it a few years back at a drag race thing we Pantera guys did
and it still lasted a couple of more years.. I am sold on them

I know most use double disc fancy this and that but the tried
and true seem to work for me.. my 2 cents

While I haven't had time to touch the car since coming home from Nationals, Dave Nutting has been busy working with it...as seen here.

Thanks for the pics and article Dave, you did a great job shining up this turd!

Awesome! Congrats to you and Barney! :thumbsup:

Nice write up by Dave too. :)

GO Barney GO ! I wish I could get a ride in the SS.:flag2:
