$1,000 on the Nova, because you'll spin.

Looks like this now

2 dominators fiberglass fenders fiberglass doors lexan windows. Leaf spring

You keep asking how fast our 60' are... how quick is
your 60'

Dumb question... Probably not related the the OP's post, but does the location of the front spring eyelet, on other words angle of the front leaf segment to the ground or chassis, have an affect on axle rotation with a cal trac?

I'm know with a ladder bar car lowering the front heim into a lower adjustment hole Softens the hit on the tire, and vise versa, raising the heim attachment makes it more violent on the tire

Yes it makes a difference if the spring eye is higher
or lower.. that is the IC.. on a leaf you cant cant the
IC length(unless you change the length of the spring)but
you can change the height... just like a ladder bar...
but it can change if the spring is rapping up

Everyones common response when you are not saying what they want to hear............"well what do you have, or come show me".

HOW to FIX the car has been covered in depth, by more than just me. We are ALL telling you the same thing, but you refuse to listen........ Aside from the spring issue, the car does NOT need wheelie bars. If it is riding the bumper and crushing pans, it's not set up right. We got guys going 3.90s on radials, not crushing oil pans with no bars, don't see why yours needs them. Last time you brought that up, I told you it needed more front percentage, better shocks and learn how to use them. You didn't listen to that either. You put bars on it and now have another issue, because of trying to "crutch" the first issue

But yes, you are 100% correct. I do NOT currently have N/A, leafspring, smallblock, small tire car. So I am in no way shape or form qualified to give suggestions on how to make one work............I'm out

Same here.... hope it works out for him

I have posted Time Slips before 1.24 is the best so far many 1.25 then I relocated the shocks and added wheelie bars and got lost.. the guys that I run against Run there Wheeled bars 16 to 18 inches high. Not possible with the long trunk of the Dodge Dart I'm at 13 inches Max I even had to cut the back bumper.
I'm going to pick up a stiffer front segment and replace the front and rear at the same time.. also shorten the wheelie bars. I'm not sure about getting rid of the lowering blocks just yet I run the flattest leaf spring the Calvert sales already.. the lower I get the car the better mph seems to get.. if I cut the frame rail and move the slider up into the frame. I'll be able to get rid of some lowering blocks... I'm currently making some changes that could possibly take some of the hit at the starting line away.. and I appreciate everybody's input positive and negative...

Did he post his f/r percentages? If so I can't find them. I know many want all the weight on the rear they can get but you can make a bunch of grief going to much.

There is a reason why pro cars are built under minimum weight and made to move weight around 25 pounds from rear to front is a big move.


Best of luck to the OP. Sounds like a monkey see monkey do guy. All his buddies have wheelie bars.

to be honest, and this is an observation from waaaayyy up on top of the porch, I believe the wheelie bars came into play as a "safety valve" to protect against further oil pan damage.... I'm betting if he gets the car to perform to where they are not needed.... they will disappear.

whatever the outcome... I hope it hooks, goes straight, and gives that Chev II a good look at his tail lights. It would be a good day out here in the west if that happened....

AS to the NA question. The ONLY way these cars go fast is hit them with everything from the get go. Thought I covered this but maybe not. NA cars do not respond well from having timing pulled, pulling timing is a badaid for bad set up or poor track. NA cars do not have the luxury of ramping in hundreds of horsepower and pouring the coals to it.

Or are you telling me that the car pictured is hitting it with everything he has right from the hit? Or is his system on a controller or timer to allow the car to get moving first before pouring the power to it. This is something an NA car simply cannot do. Been doing the NA stuff for a long time and there are occasions when we have to pull timing due to poor track conditions and it simply kills the 60' and 330 numbers. Well that aint gonna make for a fast pass at all.

As for weight bias. A lot of guys are hung up on that 50/50 number. Great for a stocker or bracket car but once you start running fast that is exactly the wrong thing 99% of the time. On a leaf sprung fairly fast it woud definitely be the wrong way to go. We have worked very hard to get to 56/44 and it has made a world of difference getting the car much happier and less violent

Well I will tell you the fast guys are going 4.30s with there turbo cars this year in x275. Ron is going 1.04 60fts and only in the 4.40s in a heads up class that he has won many championships and ducks race in Georgia this February. So I don't think he is holding any thing back and is hitting it with all it will take and not spin. It's a sb nitrous car it is down on HP in this class compaired to bb nitrous cars and the turbo cars so he needs to out 60ft and 330 them to win. A top x275 turbo car goes 165 he only can get 155 out of his combo so he can't hold back and pour the coals to it as you guys like to say.

Then I guess I am wrong....From my experience he is the exception not the rule.

Besides we are talking caltrac set up not grid programming. Don't see a difference in your suspension set up being na.

If it was me I'd just hook up a go pro and shoot some suspension video. Send it to the boys at Calvert and get a pro opinion. If you have the money and you really want to hook the car up then set up a data system. Shouldn't be hard to mount up some motion sensors on the shocks as well as wheel speed, driveshat speed sensors.

Basically you have 10 pages of arguments here since you don't have any data. If you had the data then you could just tune the car and you wouldn't need 10 pages of opinions.

Just sent you a text, Shiloh.

There is SOME video data. He runs the bars as high as he can, when he drops the button, they slam the track. The housing is rolling badly. NOTHING matters until you fix THAT

I'm hoping that a stiffer front and rear segments helps in this matter. Everybody wants to throw rocks and that's fine.. but I listen to all you guys and I learn again I don't want this to be a rock throwing match I was hoping that this would be some good leaf spring information for others... as well as myself

You asked
