ok. ive went to aluminum heads..car has lost a total of about 100 pounds..700rf, 600 lf, 200lr, 150rr..running a track shaped like a paper clip with some banking..car was excellent in years past..now it wants to push in the center of the corner which makes it suck off...tried stagger, more rebound control on lr, softening lf spring...last year ran 750rf, 650lf but by losing the weight thought i might get by with going softer, also running about same percentages as last year 57 rear, 52 cross(about 100 LR BITE) and 53.5 left, pull bar in bottom hole using the biscuit, bottom bars in top hole and left upper bar up one higher than right..appreciate any feedback on this thanx.
its a dirt works dw7..

Have you scaled the car since you put the heads on? Your talking about 4 percentage points from what you had. How are you running the same percentages minus 100 pounds on the front?

yes, we scale the car every week..didnt lose 100 off the front, just total..after putting on the new heads, i was able to take off the ballast i had in back in order to achieve 57rear, which ended up totaling 100 pounds off the whole car..i just went with the ride heights i had last year when i scaled it...i also run about two inches of rake in the j bar...thanks!! another thing is run about three eighths inch lead in the right rear..and have for five years, think its time to bringér back a little?

I HAVE FOUND FROM MY OWN EXPIERIENCE THAT LEADING THE RIGHT REAR WHEEL IS JUST A CRUTCH FOR WHEN SOMETHING ELSE IS NOT RIGHT WITH THE CAR. I ALSO HAVE FOUND OUT THAT RUNNING ONLY 1/4-3/8 LEAD CAN LEAD TO A PUSH ON CERTAIN TRACK CONDITIONS. I RUN MY REAR SQUARE IN THE CAR MOST OF THE TIME AND WORK WITH OTHER CHASSIS THINGS LIKE SHOCKS, OFFSETS, STAGGER ETC

I switched to a DW-8 4 bar this year and ditched it after 4 races. I like the bite it got but after dumping a spring one race, snaping a u-joint becasue the drive line slamed into the trans from so much travel and taking out my tailshaft as well, I decided to throw in the towel and try a 2 link. But...here is what I learned

It sounds like you have just wat Dirtworks recommends as a starting point and when we tryed that, it had a HUGE throttle push in the middle of the turn...sound similar???

WE...dropped the bottom bars to the bottom hole or just flat. I use a Monty bar and had to raise it to the 3rd hole up. That alone may a big difference but the last night I found the problem...The panard bar. DW recommnds a 9 inch shorty and for me, it was way too extreme at an 8 inch drop!!! I flattened the bar and the car was finally drivable. If I was going to stick with the 4 bar, my next move would have been a 30 inch panard behind the rearend.

The pull bar might be an area to look at as well. Mine was too steep and the bite hit too hard, too early and caused an instant push when I got on the gas.

I changed every spring and shock you can imagine and noticed very little difference. The hardest thing for me was to stray from DW's setup. I finally started to listen to one of our local guru's and he was right.

Good Luck!

THIS IS MY TWO CENTS, TRY LOWERING YOUR LEFT REAR BOTTOM BAR.
AT SUCH A STEEP ANGLE THE BAR CANNOT SWING THROUGH ITS ARC. WHEN YOU FLATTEN THAT BAR OUT YOU ARE PUTTING MORE FORCE ON THE LEFT REAR TIRE BY INDEXING THE BIRDCAGE MORE. THUS DRIVING THE TIRE DOWN AND THE BODY UP. WHEN THE BODY GOES UP IT WILL ROTATE YOUR ARMS AND INDEX THE BIRDCAGE. IF THE BOTTOM BAR IS ALLREADY ANGLED IT HAS NO PLACE TO GO. WHEN YOU DO THIS IT MAY TAKE A 3 OFF RIGHT FRONT WHEEL AND POSSIBLY SWAPPING FRONT SPRINGS, RUN SOFTER ON RIGHT OR STRAIGHT UP 650 ACROSS FRONT. TO KEEP FRONT END PLANTED. I AM SHOOTIN YOU STRAIGHT, BUT BE CAREFUL, TOO RADICAL AND YOU DEFINITELY WILL BREAK PARTS, I HAVE.

much obliged for everybodys input...not bragging but we are a very competitive car against some very stiff competition and the car just isnt performing as it has in the past...would losing the 100 pounds off the entire cars weight make that much of a difference in the way i'm setting it up and the way the car reacts to certain changes..does it magnify a change? maybe somemore stupid questions, but wouldn"t stiffening the left front make it tighter still in the center and by lowering the bottom bars, doesn"t that take roll steer out which would make it tighter? not questioning anybody, just going off what ive learned over the years, appreciate yours guys comments!!

I WAS JUST OFFERING MY OPPINION BASED ON MY EXPERIENCE AND WHAT I HAVE DONE AS WELL AS WHAT OTHERS IN MY AREA ARE DOING. THAT FIX MAY NOT WORK FOR YOU.
ON THAT BOTTOM BAR, TRY DISCONECTING YOUR SPRINGS PUT THE REAR AT RIDE HEIGHT, RAISE IT UP 3 INCHES AND JACKSTAND RIGHT SIDE. LET LEFT REAR DOWN AND NOTICE NOW MUCH MORE TRAVEL AND HOW MUCH MORE THE BIRDCAGE WILL INDEX IF THE ANGLE IS TAKEN OUT OF THAT LEFT REAR LOWER BAR. THIS IS WHAT I WAS TALKING ABOUT IN MY FORMER POST. ADJUSTED RIGHT IT WORKS, IT WHEELIES TOO. I AM SUGGESTING THE SOFT RF TO GO WITH THE LOWER BAR CHANGE, THE INDEXING OF THE SPRING WILL LOADS THE LEFT REAR AND WITH A SOFTER RF WILL ALLOW THE CAR TO ROLL OVER ONTO IT. THIS ALLOWS YOU YOU TO USE THE RIGHT FRONT TIRE TO DRIVE THE CAR THROUGH THE CENTER OF THE CORNER. GOOD LUCK AT THE RACES HOPE YOU GET YOUR PROBLEMS WORKED OUT.

Usually a tight condition only in the middle will show up as a geometry deal with the RR. If you raise the chassis side of the lower bar, then it cause the rear to roll more toward the rear, which is exactly what a lot of late model drivers do. If you have the tack, this is something that can cure it. But by raising the lower bar on the chassis side, you will also enhance forward bite also. It will help somewhat. That is what I would look at....

my two cents.

thanks billy bob and everybody...i"ll try your suggestion this weekend..the car is usually very good, i usually just tighten it a little in between heat and feature for when the track goes away..i did try the stiffer lf than rf a couple of years ago in a heat and it cornered excellent but when i came in the right rear was on fire and no heat in the left rear, so i switched it back before the feature thinking it was go loose on me and i never really went back and expanded on that set up further..also billy bob, a late model friend told me some time ago that if i went to a stiffer lf than rf i should also run a stiffer lr and run more wedge..any thoughts on that, ive yet to really try that..weve been winners in the past so our set ups have been good and i never really did alot of experimenting..its just these first three races of the year with the car being lighter where its not comfortable..but i will try that set up you mentioned billy bob and let you know how it went..thanks again..

The tire temperatures are telling you exactly what you want to know. I have had the same type situation happen on our mod when we didnt have enough wedge in the car. Also....when adding more wedge, sometimes, you allow the car to turn more freely because you take away sidebite when adding wedge. Just a thought.

YES, YOUR FRIEND IS RIGHT, THE LACK OF WEDGE OR LEFT REAR BITE IS PROBABLY WHAT GOT YOUR RIGHT REAR SO HOT, THE CAR WAS LOOSE ENOUGH THAT YOU WERE RELYING TOO MUCH ON THE RIGHT REAR TIRE. WEDGE, LR BITE (ALTHOUGH 100 LBS SOUNDS ABOUT RIGHT) OR THAT BAR CHANGE I SUGGESTED SHOULD HELP THAT PROBLEM. NOT WORKING DIRECTLY WITH THE CAR IT IS HARD TO SAY. HOPE EVERYTHING WORKS OUT GOOD FOR YA. LET US KNOW.

I'm curious to hear if you were able to cure your problem. Did you try Billy Bob's suggestions? If so, how did it work? This is my first year with a 4-link and like to hear how different set-ups work.

yeah, i tried going down one with the left lower bar and i also switched to 700lf and 650rf..also when i scaled it i went to a little tighter wedge setupand i also switched to a 93 shock on the left rear...ive ran twice with this same setup and should have won once with it but circumstances got me..it will on occasion carry the left front off, not all the time, just how you come off i suppose....i did notice im getting alot more equal shock travel on the rf, lr and rr....i also noticed the other night the track, which has been tacky, slicked out just a little bit and the car really felt good, had good heat in both rears when i came off....in the dash and qualifying im still getting a little push in the center so i took wedge out for that and it seems to help and then put the wedge back in for the feature.....try it, it wont put you in left field..

hey billy bob, just wanted to let you know we picked up our first feature win of the season this past saturday using some of your suggestions..should have been two in a row but things didnt work out the week before..i went down one on the lower left bar, went with a 700lf, 650 rf and ran a little more wedge and also ran a 93 shock on lr..it rained like **** in our area so the track was very hooked up all night long..and youre right, it hooks up off like a sob, carried the left front tire several times and flat wore my *** out before it was over..i was fast as **** in one and two and quite pushy in three and four, i put more wedge in before the feature thinking the late models would slick it out just a little but they didnt, so much for my track reading skills..anyhow ive noticed more even shock travel at the rears and rf and the car has been excellent off, pushing if anything and ive never had that, weve always ran dry slick tracks where its more finesse and this track isnt doing that yet, maybe when we get a little further into the summer..anyhow i appreciate the input from you and your straightforwardness..from past experience i know what certain changes should do to the car, but didnt always know exactly why especially with this four bar..to give you an idea how this track has been, ive ran the same d 40 tires for three weeks and they are not hurt one bit, no kidding, three weeks, thats how moist this track has been..anyhow thanks, hope i can repay the favor..

DIRTRACR,
THAT'S GREAT, I'M HAPPY TO HELP. NO FAVOR NEEDS TO BE REPAYED, JUST START WHIPPIN UP WITH IT.

JUST OFF THE TOP OF THE HEAD, IF THE CAR FEELS GOOD EXCEPT FOR RIGHT IN THE CENTER IT PICKS UP A LITTLE PUSH, I'D PROBABLY LOOK AT WHEEL OFFSET AND AIR PRESSURE, THEY ARE TWO THINGS THAT SOMETIMES DON'T GET CHANGED, BOTH OF THEM CAN BE TUNING TOOLS.

ANYWAYS GLAD TO HEAR I COULD BE OF HELP, GOOD LUCK TO YOU.

billy bob, not as good this week..cut a tire in the feature, dnf..also we did not make the fast dash for the first time this year..the car is just incredibly tight from the center off, especially qualifying..i get on the gas and it picks up the left front and just goes into a big push..the car was tight off last week with the win so i went back with a little looser wedge setup than last week..after qualifying, i went down with the left upper bar, up with air on rr, and stiffened both rear shocks..since i won the dash and led all the laps of the feature last week, i didnt get to see how it was in traffic..it makes it hard to get under somebody and get them coming off..the car seems to be looser in and push off, i tried adjusting my line and entrance speed but it doesnt seem to help...the rr shock has started to bottom out so i think im going to stiffen the rr spring 150 to 175 and hoping this will get it in better and some push out coming off..i guess you would have to be there to apprciate it, this track has long fast straights and tight corner, shaped like a paper clip..its heavy and greasy early and then seems to get tacky and somewhat rough later..we"ll keep working with it, it is definitely fast we just to tweak on it..i kept the left lower bar down one and left the front springs as is 700lf, 650 rf...thanks again for all your help..

SORRY TO HEAR ABOUT THE BAD LUCK LAST WEEKEND. ARE YOU RUNNING A J-BAR OR STRAIGHT BAR? THE STRAIGHT BAR IS TOUGH IN TRAFFIC. SOMETIMES WHEN TRYING TO COME OUT LOW I SPIKE OR RIDE THE BRAKE(DEPENDING ON TRACK) WHILE STAYING ON THE GAS. IT SOMETIMES WILL PULL THE NOSE BACK AROUND JUST ENOUGH TO COME OUT LOW AND STRAIGHT. ALSO SHOCKS ON FRONT. I TRY TO STAY AWAY FROM SPLIT VALVES. EXAMPLE 6-2 ON RF WILL TIGHTEN HER UP ON EXIT. LIKE I SAY THERE ARE SO MANY ADJUSTMENTS, I'M TRYING TO SPARK IDEAS THAT MAY HELP. PANARD BAR ANGLE, AND STAGGER. I LIKE A 26.5 LR AND 27.5 RR ABOUT 3" OVERALL IN BACK. 1" UP FRONT. GOOD LUCK THIS WEEKEND DIRTRACR.

P.S I AGREE WITH THE 175 FOR WHAT IS WORTH

yeah we run a j-bar, with about two inches of rake...second hole from top at the pinion..i do also run the 6/2 on the right front..thats a good point..besides the rr spring change im going to start out with the left upper bar down one from usual, third hole down on this dirt works..also going to go with about two inches of stagger, more than i usually run..like i was saying before once we get into more hotter weather around here im anxious to see what she does when the track gets slicker..cause ive sure never had her this tight coming off the corner regardless of the conditions...we will tweak on her a little bit for qualifying and go from there..
like u said there seems to be endless adjustments you can make, we"ll get her..**** , i already owe you for one feature win, you seem to have a good handle on stuff and i appreciate your input..thanx again..i get back and let you know how she goes this week....

billy bob, finally got on that slick track over the weekend..mixed results with the setup weve discussed...the track was smooth as glass and slick as ice, three eighths mile..went back to the 150 on rr, left the bars alone and the springs in the front were the same as we discussed..car was awesome in the heat, seventh to second and was very hooked up on the bottom...feature time, i dont have a clue what happened..i hung 20# on right rear, which ive done in the past with no ill effects and also ran about half inch reverse stagger, something ive also done with no problems..car was good for about three laps and then proceeded to lose every bit of forward bite..then with about five to go the car seemed to come back to me, passed back a couple of cars that had passed me..the track stayed pretty consistent throughout the night smooth and slick and was somewhat abrasive, feathered my d40"s pretty good..also when i came in, the rears were warm but not hot and the left rear had pretty good heat in it...so go figure..doing my weekly maintenance this week and going to make sure we dont have a birdcage or something binding..never in ten years of racing have i been that good in a heat and then go backwards like that in the main but thats racing..maybe i should have left it alone after the heat but i was just trying to keep the car good for the end of the feature..anyway any thoughts on why it may have went away so bad, like i said the track stayed real consistent and was really good in the heat..this is a different track than before, a track weve had much success at in the past..with the car coming back to me later in the race it makes me think it wasn"t the tires because the thing ive noticed with these d40"s is when they go away they"re gone..think maybe i should consider going back to last years setup, the one i mentioned in my first post...maybe stiffer rf..its a little different situation than what we started with at the beginning of the season, no tightness in the center on this track..

HEY DIRTRACR.
TO SATIFY YOUR CURIOSITY I WOULD TRY YOUR LAST YEAR SETUP. NOT KNOWING YOUR TRACK IT MAY BE WHAT THAT SLICK TRACK NEEDS.
ALSO CAN YOU RAISE YOUR LEFT REAR UPPER BAR A HOLE TO LET THE LEFT REAR DRIVE UNDER A LITTLE MORE, A LOT OF THE FORWARD BITE IN A FOUR BAR IS ASSOCIATED WITH LOADING THE LEFT REAR. I AGREE WITH STIFFENING THE RIGHT FRONT SPRING TO TIGHTEN CAR. WATCH FOR SLIGHT MORE PUSH ON ENTRY THOUGH. IF YOU LIKE TO RUN THE BOTTOM, MORE J-BAR ANGLE WILL HELP. I LIKE TO RUN 3 HOLES DOWN ON PINION AND 4 HOLES UP ON FRAME. ALTHOUGH THE TRACK GETS SLICK I RUN THE SHORT BAR ON MINE. IT LIKES THE BOTTOM ON A SLICK TRACK. ALSO THE WEIGHT ON RR IS INTERESTING, RR LEAD TENDS TO LOOSEN UP A CAR, ALL THE LEAD I HAVE ON MINE IS A 60LB BRICK ON BAR IN FRONT OF CELL UP TOP LOCATED IN CENTER OF CAR TO MAKE UP FOR FUEL LOSS. (AND TO ROLL THE CAR A LITTLE MORE) IF YOU HAVE ANY QUESTIONS I'D LIKE TO HELP IF I CAN, HOPE THIS HELPS YOU OUT THOUGH.

i may do that, haven"t made up my mind yet..the car was excellent in the heat..i do have the left upper bar a hole up from normal.also when scaling the car i put the twenty pounds on the rr rail and it didnt seem to effect the left rear/right rear weights that much, just added more rear percentage, ive run it like that many times with no ill effects, have won with it like that..after a couple days to think about it, i just wonder if i shouldn"t have bolted on a couple of old tires for the feature instead of new ones, the newer tires alway seem to be softer on the durometer..i had on old ones for the heat and it was excellent..i"m really kind of clueless on this one..the car is the same as in the past, done the same adjustments in the past, adjustments ive won many races with on this track, portsmouth raceway park in ohio, only thing that is different is it"s 100 pounds lighter..i figured with the pushing off problem i was having on the other tacky/heavy track we ran that it would really shine on the slick..i know alot of the late model guys run the softer rf on the slick, rocket chassis cars, but dont know how much that would really apply to a mod..we"ll play with this week, ill let you know how it turns out..keep those comments coming i appreciate your input..

I HAVE BEEN RUNNING SOFTER ON RF FOR SOME TIME NOW. THINKING ABOUT YOUR SITUATION THOUGH IT SEEMS THAT IT IS POSSIBLE THAT ON A VERY SLICK TRACK IT IS NOT ENOUGH SPRING TO HOLD UP THAT CORNER AGAINST THE LR. WHAT I MEAN IS THAT THE SOFTER SPRING IS ALLOWING THE LR TO UNLOAD TOO MUCH. THERE ARE TWO WAYS YOU COULD GO. FIX IT WITH THE FRONT SPRINGS OR ADJUST THE REAR SUSPENSION TO LOAD THE LEFT REAR MORE. (I RUN THE SHORT BAR WHICH WILL ROLL THE CAR UP AS THE PINION ROTATES. BUT J-BAR ANGLE WILL ALSO DO THE SAME.)
THE REASON THOSE LATEMODELS RUN THE SOFTER RF IS THAT IT ALLOWS THEM TO DRIVE THE CAR STRAIGHTER AND DEEPER INTO THE CORNER. IF YOU HAVE ONE MORE HOLE UP ON THE UPPER LR BAR I WOULD CONSIDER IT.
USUALLY(MY EXPERIENCES)A NEW TIRE SEEMS TO REALLY WORK UNTIL THEY GET HEATED UP THEN FALL OFF. AND AN OLD ONE THAT HAS BEEN HEAT CYCLED WILL LAST. BUT YOU GOT FASTER AS THE RACE WENT ON. POSSIBLY AFTER ENOUGH FUEL BURNED OFF TO COUTERACT THE LEAD. IS IT POSSIBLE THAT THE WEIGHT CHANGED THE CAR JUST ENOUGH ALONG WITH TRACK CHANGES THAT THE CAR REACTED A LITTLE DIFFERENT THROUGH THE CENTER OF THE CORNER AND THAT WAS HURTING CORNER EXIT? GOOD LUCK WITH WHATEVER YOU DECIDE. TRYING TO HELP THROW OUT IDEAS. BILLY BOB

well where do i begin..decided on 700rf, 650lf, 51.2 cross about 120# of left rear..still got 200lr, 150rr..57.3 rear..left upper bar up one from normal, bottom left back up in the top...drawed a bad pill, started way back in the heat, track slick as ice, got up to fourth behind cars i run with or out run caution comes out and when we go back to green, they get away..come in about half peed off..went down one on the j bar on the pinion, up one inch on the chassis side, switched from a 5.14 to 5.00 gear, added more wedge which puts it up to about 52.3 cross and switched back the front springs to softer on the right front..come from 19th to 6th..but it still aint where it should be..just getting killed from the center out..this is a track ive won four track championships on and its got me clueless...i dont know what the deal is, i had the rear end apart last week, no binds..everything checks out..the adjustments ive done in the past and won with just aint workin anymore for some reason..im either slower or their faster..weve got a strong motor so its not that..im thinking of moving the rr spring in front of the axle and doing away with the j bar and running a straight rod to the drivers side of the pinion..we just dont know what the deal is..this track is like ice so i dont think ive went to far with an adjustment..it seems to be gettin in the corner good maybe skating out just a tad in the heat thats why i adjusted on the j bar.. just wont take the throttle and im usually good with a soft foot..ill keep after it cause i aint no good at gettin my **** kicked..ive also got three eighths lead in the rr...got 75-3 on lf, 76-2 on rf, 93 on lr and a 94 on rr for shocks..i just dont see why it doesnt want to take the throttle like it should..the biscuit was bought new at the first of the season, a medium, and i keep about an eighth inch pre load on it.. it should be going..maybe i cant see the forest for the trees..i sures heck run a lot better than what ive been showing especially on this track..weve also got the progressive link on the carb....seems like the doggone thing handled better when i had the cast heads on it and it weighed 2500 pounds..

How much traval in the rr and the lr? What size springs in the rear 13? What are they at ride height? I have learned a few things in the last few weeks that made me wonder!

13's on the rear..rr shock lacks about an inch from bottoming, lr about two maybe two and a half..never have checked the spring height at ride height if thats your question..dont think their binding, wouldnt rule anything out at this point..

Not looking for binding but looking at the preload of the spring at ride height i have found that by adding more preload without changing and ride height the car would be a tad loose in the middle back it off and the car would stick and drive right off, Just things that i have found with my car 6 link swing arm car.
