Smackdown help!

[TEAM56RACER]

Entry was better, the car got on the bars better than normal. It would enter on the bottom pretty good, then from the center off the driver would just have to chase the RR up the track. And as far as lead goes, its got 20lbs low right behind driver, and 20lbs just left of 90/10 shock mount, and 40lbs behind the dry sump tank, 30lbs on the front ballast clamps that hold the fuel cell in. Overall the changes that we made seemed to help it. Its just got to drive off the LR more than it did.

If he's chasing it up the track it sounds like to much rear steer or rear trail. Drop the LRL down a hole or it you have the Right side bars lengthened undo it. You don't want to lose your entry but I would drop the LF to 450 it will free up entry but when you take the rear steer out for your exit drove and tail out feeling that will still allow it to get in. I'd look at the LRL unless your not dropping the LR on entry and holding rear steer in if you are drop the RRU bar the second hole from bottom if it's 4 bar and seriously look at indexing on the LRU birdcage it's a very effective change. What is your shock setup?

[7uptruckracer]

Definitely post your 5th coil travel I saw you said it was a 350 at 34" post what motor your running too that derives most your drive and the bars tune the balance of it

[TEAM56RACER]

7uptruckracer, I'm not sure how much 5th coil travel it has in it right now, I'll check and get back with you on that. The current motor is a steel block, brodix headed 358, 650hp. The other motor that we run is an all aluminum 420, there is about 150hp difference in the motors but you sure can't tell it with the way the car is working now. So for now the little motor is plenty. We won the heat by a straightaway, track had some moisture and the car worked pretty good. Started 3rd row inside in the feature, track was slick. Although we are getting closer we still finished 5th and not much improvement in forward drive. I took roll steer out, added LR bite and also went to the 450 RF spring. I'm limited on how much rear stagger I can take out, its either 4" or all the way down to 2". Would 2" of rear stagger be enough? It sure seems like it could get away with a lot less than 4"

[7uptruckracer]

The 5th coil and shocks could be your key. Unless your at a high speed banked track most won't be as stiff as that 450 RF, most my cars are 350-375. While it might be looser off i tend to think of loose and drive as related but a little different at the same time over rotated and the inability to go forward are two different problems. I would stick with 4" definitely shoot for the closer side to 4" of 5th arm travel if you don't have it change your 5th coil spring 25# at a time till you do As far as how forward for back it is you want far enough back for traction until you get wheel spin from to much instant, High HP motors are normally farther forward around 38" and lower like stock heads or crates are farther back, but still the same travel range 3-4" the more travel the more torque your absorbing so he can throttle up without shocking the tires. Sounds like your doing well just need to keep up with the changing conditions more.

[7uptruckracer]

I"m around 275 on our Steel Block Brodix head car. It is a Rocket Chassis but a 4 link is a 4 link it just depends on your engine combo, driver if hes a light switch gas pedal driver or a finesse driver.

[hot rock]

How much travel on the 450 did you have during the race vs heat race.with the dryer track conditions your prob not compresssing it enought or on it enough to get more drive rolling up on it instead of down on it. I think i wouldnt change nothing for heat race this wk try lowering left lower bar maybe a wheel spacer on rf when slick .and i wouldnt be scared of 2inches of stagger in the slick

[TEAM56RACER]

Our driver is definetly aggressive on the throttle, on slick track conditions he does seem drive in too deep and let the car over rotate some. I have also thought about a 2" wheel spacer on the RF, and I am questioning the 5th coil location and spring rate. As far as RF travel from the heat race to the feature, I'm not sure how much but it was alot less in the feature.

5th coil should be good if the driver has any finesse whatsoever

[7uptruckracer]

I dunno MasterSbilt he just said hes aggressive lol I agree a 350 isn't unusual but thats why I mentioned it and the travel is it possible its a wheel spin problem and not actual drive? I don't mean to come across condescending if I sound that way but on super slick tracks you may never get full throttle, and it sounds like you have a dialed in car in the earlier nights if you pulled that kinda heat race lead. If he is driving in to deep we can't fix that you can't use all your traction to get you in then you can't get it off

[powerslide]

I didnt make it down to watch this weekend and dont watch him specifically but i dont think its the driver. He's aggressive but i wouldnt say over aggressive with the throttle. He has alot of laps in different kind of cars, dont think he has wheeled a late model much though. But at 650hp on a 14in tire he shouldnt have too much wheel spin issues. He's young and likes to bump it off the cushion(pronouced Cooshin if you are The Don "BendYoSteal" O'neal). I say he needs to spend a bit more time tuning on the car

[tin man]

Have you tried or thought about trying a progressive spring on the lift bar when the track gets black? Weve used one our smack with favorable results . Also the rf spring seems way heavy. Were down to 250# and the car rotates well getting in has good traction off the corners

[7uptruckracer]

I see I see well post your shock package and the new style not the old style progressives you see on ebay (for a reason) work ok. They will either like it or hate it, and if you run one track that could be an option Ive seen them on tracks alot that stay one way all night not tracks that go from heavy to glass slick just my observation. Definitely get some 5th measurements and post your shock package, if you run chains on the LR and/or RR I think everyone would like to see you on the softer RF in here though you shouldn't have to go outside the box to far to get the car to react in a favorable way and make big gains.
