how get wheels out the air on my 4 link car ** VIDEO ADDED **

my car has all ways did big wheel stands with the small motor 521 i had a 1.24 60' @5.80 on motor 3000lbs
with my new motor 600" a460 head motor i think it will be even worse

some back half cars just wheely, i'd say you need to talk to a chassie guy,

You will need to post more info about your chassis set-up before anyone can give any constructive advice on which direction you need to go.
Looks like horsepower isn't a problem though...lol.

The first step will be to limit the amount of travel you have in the front suspension. You'll be suprised at how much difference that will make.

x2 on what curt said ..... install some front end limiters to ease the launch

btw im going to move this over to chassis section ..... im sure Dave will chime in

is this a 4link or stock suspension what shocks are you running in front and rear front limiters will help out 2.

Put a chevy in it.



Sorry, couldn't resist.

Truth be told it might not carry the tires as much with more power.......or it might shoot for the moon. Just depends on how close to the "ragged edge" you are on traction at the current power level. You wont know for sure which way it will go until the first T&T outing.

Got any good launch video? (not on photobucket I hope)

MY CAR IS 4-LINK , FUNNY CAR CAGE,16 POINT ROLL CAGE 1-5/8, STRANGE DAJ COIL OVER IN REAR 110LBS SPRINGS , C-MOLY ANTI-ROLL BAR , C- MOLY 4-LINK , UPR C- MOLY K MEM ,C-MOLY 9" WITH ALUM.

THAT'S A GOOD ONE , SORRY I DONT WANT MY CAR TO END UP IN THE SCRAP YARD WITH THE REST OF THE CHEVY'S THAT WANT TO RUN LIKE A FORD!!!!!!!!!!!!!!!!!!!!!!!!!!

HERE ARE 2 VIDEOS TO CK OUT ...... THE CAR DEFIENTLY 60'S HARD REMINDS ME OF TEAM SHERRY'S CAR

2nd video was a good looking launch. I wouldn't change a thing.

Like the priest said to the guy at confessional, "Are you confessing or bragging?'.

That's not what I'd call a big wheelie. If it goes 1.24 @ 3000 lbs., I wouldn't screw with it until I saw a few runs with the big motor.

I agree. Now if it was draggin the bumper then thats a different story, or if this was a full blown chassis car it might be a bit much as well.

the 1st video of my car it was on the bars hard for about 200ft the #2 video i had the bars lower than the frist one but it was spinning when wheels came down i was only on a 29.5x10.0 i think that my new motor will be too much

It may be true that your big motor will be too much for your current setup.....HOWEVER, if that car weighs 3000 lbs., and if that tire is a 29.5 X 10.0, and if your 60' times are in the 1.24 range, then I think you've stumbled upon one helluva good chassis setup. I'd still run it with the big motor first. Otherwise you're spending a pile of money to fix a problem that you don't have.....yet. JMO.

I agree with maverick. I'd try it with the 600" motor first and then adjust accordingly. You could always lengthen out the 4 link instant center to calm it down if need be.

Only repeating what others have said, looks pretty damn good compared to many.

First and foremost control the energy released in the front, you want the transfere, but not a lift to the moon.. so with some form of adjustable travel limiter (chain works great) you can stop the energy in the spring from pushing off at a certain point.

Second, looks like the ideal wheelie bar height is about an inch higher than the last run. On the bars isn't a terrible thing, but HARD, the chasis is continueing to lift and can actually unload the slicks with weight on the bars, then the front comes down hard and unloads the rear again.

Trial and error.... because no two back half cars are exactly alike. I would start working with a travel limiter up front. And see if it nets enough results that no other changes are made. If not, then it might require playing with the 4 link mounting points and change the weight transfere geometry.

1.24 is really good for a 5.80 car at 3000 lbs.......like mentioned, try out the new motor with front limiters.....they DO work.

my goal it to race with out bars cant i move the 4 link bars and make this thing stay on the ground? i have saw car that are faster than mine and have no bars , and thay dont even pick the wheels up . can someone tell me how thay do it?
will the weight of the a460 block vs the stock block be enough to keep it on the ground.
plus i have went from 1 carb to 2 carbs and a tunnel ram that has to way more than my old one

take the top bars and move them up one spot this should help, We are not allowed sissy bars in our class either the best thing to do is try to hit the tires harder to make it spin then its a balancing act on small tires. the limiters help on the front almost every car in our class has them.

the last time i moved the top bars up 1 bolt hole it hooked even harder
you do know that my car is 4 link
logan

how would you make the car push and not lift? hooking aint my worries watching the sky is!

Put some weight in the nose.
