g body road course

[malibu43]

so do you like it?,Any chance to sponsor my car Ramey? haha
thats why always i said any help will be apreciated,the car has been developed with a lot of questions,and a lot of blood ,sweat,and tears

[malibu43]

ray i thoght that i send you the pics with the car done,like you said the headers are in the right way,i never liked it how the other cars looks like it,otherwise i had to cut the sides of the fiberglass hood,and i like the way it is,if you can see,the hood has three parts,one are the fenders witch are welded to the body,two its the front of the car the red piece,and the other its the hood itself.looks nice don`t you think?

Hi Jorge,

Are you permitted to reinforce the A-arms "for durability under racing conditions"?

Hot work can sometimes do funny things, like making some things a tiny bit longer and others a tiny bit shorter . . . and some welders are absolute artists . . . I think Ray knows where this is going.


Norm

[malibu43]

Norm,i think i got a little clue for what are you talking about,but my technical english its not the best,thats why always ask for pics,so if you have some .... will be great.
thanks

[malibu43]

i forgot to tell you guys,i did some trick with the lower a arms,i made other holes to the frame so the lower arm when a little outside of the car,but the rules inspector CATCH ME.jajaja,so i had to go back where supposed to be stock possition.

We used to run a '76 Monte Carlo street stock on asphalt. We were only allowed stock steering components in the stock location. You'd be surprised how a frame repair after a crash can fix bump steer...

[malibu43]

ramey,tell me more about it,

[UMI Tech]

Bump steer is caused when the lower a-arm and tie rod travel in a different arc. If your car has bump steer you can change it by raising/lowering the mounts for the steering (i.e. the steering box and idler arm). We had crashed one time, actually many times, but one particular time we cut the front end loose and moved it up and down until the bump steer was correct. Of course this explanation is the simplified version as it took many evenings and much measuring and testing and welding to get it right...

[exwestracer]

Ramey, I think he is already using the bumpsteer correcter tie rod ends...right, Jorge?

In case you guys are wondering, I have spent the last year or so helping Jorge off and on with the build of this car via email...

[malibu43]

yes,yes,ray,has been helping me a lot,and you are correct,i fix my bump steer problem but i have to redone again,because i change the spindles (stock ones) so i think its better to do it again.
if you guys wondering,i can tell you Ray its the man.
my next test in the track will be rear suspension,so be ready Ray to the question bomber.
its true what i ve read about the cross shafts,if you turn it 180º you can get more negative camber?but i thing not in every model,or am i wrong?

[exwestracer]

Maybe some of them. If you look at the picture in post 18, see how the flats on both sides of the shaft are the same distance from the center of the bolts on the ends. You would have to have a different distance there for it to be offset.

[malibu43]

ok my man,got it now,get ready,for the rear suspension questions.
if the car where yours,what you`l do in the rear susp,please if some pics will be great.
thanks a lot again

[exwestracer]

Better question is what CAN you do? Stock design? Stock parts?

[SPi]

We have built a few vintage race cars that run in classes with similar rules. For example, we built three C3 big block corvettes that had to have `stock appearing`control arms. so we take a stock control arm and cut, bend, shape, weld, and refinish so it maintains a stock look but gives the benefit of an aggressive alignment and much better ball joint angles. You can achieve what you want out of the stock control arms, but it does take quite a bit of time and trial and error. Also, it is smart to build a jig and fab more than one set in case you damage one, especially at the track. I will add some pics tomorrow if I have any.

[exwestracer]

SPI... Haha, on a big block C3 I could see that being a BIG advantage...

Jorge, did you ever race the 43 car without the rear sway bar? What exactly is the handling problem you are trying to fix in the rear? Sorry if you told me before and I forgot....

[malibu43]

ray i haven`t yet because the season its closed,but i will try in the track in a few more weeks,remember always the rear of my car try to pass me,i really need to make fast turns,any help as ussual will be great.
thanks

[Norm Peterson]

Ray - any chance ↑↑↑ is what Bob Bolles describes as "tight-loose"?


Jorge - SPi has described (see Post #34) in a lot more detail what I was hinting at. Cut the lower arms, space the two pieces just a little further apart than the cut width, and re-weld. Cut the uppers, butt the two pieces together, do a little edge prep, and reweld. A straight cut mm here and a couple there will be good for about 1° camber, and you could then use a grinder so that on rewelding you get a little more positive caster. You might have to do just a little reshaping to make it look unmodified. (Generally for this sort of tweaking I'd rather hint at what you might try than post what might be a blatantly illegal mod, but this one's been pretty much blown out into the open anyway).

"Pushy loose" is common in the circle track world (from whence I came).

On a side note, Bob Bolles is my editor as I'm a Circle Track technical contributor. My name is even in the front each month. I really need to get going on the UMI oval track product line...

There's links at the top of my archive page: http://www.womerracing.com/resultspage.htm

ps sorry for the self-linking but I got excited seeing a Circle Track reference

[exwestracer]

I had discussed with Jorge about it being "pushy-loose".

He assured me the front wasn't bottoming (my "go-to" check on stock G bodies). I told him to pull the rear bar off and run it to see if it fixed the problem. Apparently he hasn't yet had the opportunity. Until I had that information, I was waiting to give him any more ideas.

I'd welcome any input, and I know Jorge would for sure!

[malibu43]

ray,could be one of my problems what i told you the other day(write),when i said that i move the lower arms a little outside making a new holes in the frame?maybe i did wrong and that was one of my problems?could it be?
