Title: Transport Issues
Post by: Black Rose Racing on March 03, 2010, 11:45:33 AM
  I've spoken with a few LSR racers and read here,that after towing to a venue a few folks have opened the trailer only to find the car had been damaged in transit (specifically broken or cracked frames)
  I'd like to know if any one has had this experience and what you do now to guard against transit damage. Thanks

Find an old air bag  (Airlift, other,truck store etc.) Place under oil pan or frame low air pressure will take shock out of the chassis.  Cost me two front axles before I figured it out.

In the want ads section of National Dragster they are listed.

My dragster trailer had a block of wood bolted to the floor that the oil pan rested on for zero chassis flex on the road .

Just curious, wouldn't regular air mattresses (twin) work the same?  Would come in handy for sleeping at the Bend as well.....just wondering.

Lynda,
 If you know where I can find an Air mattress that can support a 5150 lb car please pass the info along.

 And yes we have some very heavy set crew members. They could wipe off the oil, and cuddle up on it at the Bend. Thanks for the Idea, though the crew probably won't be too excited about it.

I am so confussed....

I have trailered, street cars, show cars and race cars and have never had a problem or damage ( I guess I have been lucky)

How in the world can trailering a car break the chassis or axle ? Please explain ?

I have to tow to Maine and Utah  this year... I sure need to understand what you guys are talking about ?

Chassic flex harmonics--work hardens the the flex point

Charles, it's probable something you won't have to worry about. A lot of the lighter or more flexible frames get beat pretty badly when being towed in a stiffly sprung trailer. Usually cars of that type are blocked in some way and then tied down so the blocks support the car. It's not generally done with stock cars and that's what your cars more closely resemble.

Charles,

I have never had any problems either. I think they are talking about ridged frame cars with out suspension.

I have a front engine dragster that is ridged, so with that i have special blocks of wood with rubber that I sandwich between the floor and the rear motor mount plate, and the floor and the front motor mounts. Then I run a strap over the motor from side to side and tie it down so it cannot move. Never had any problems with the frame transporting it like that.

I can see where a ridged frame that is oh too light, with the chassis supporting extra weight, could flex enough to break if only held in place by tire straps. To much weight gets bouncing up and down while towing, and stresses the frame.

Some common sense goes along way when transporting vehicles.

Dragsters, don't know about Funny Cars, will generally use a ballon or some other method to reduce chassis flex. The long wheelbase between the front of the driver's foot box and the front axle contribute to the flex.

Those of us who live in California know to take it easy until we reach the state line then the roads no longer resemble a third world country.

On my last cars we used a scissor jack with a padded cradle for the frame rails to set on, Also put inner tubes over the front tires to prevent any chafing while in transit. Never towed with the rear race tires on the car, used rollers.

Speaking purely from a drag racing perspective the problem always seemed more severe in dragster type vehicles were I have primarily raced doorcar it wasn't much of a problem. That being said struts and hardware will wear prematurely by the movements of transport ,but it seem more so with 3-4 weekend a month match race schedule.( struts and shock wear out after a couple of seasons vs 3-4 seasons)
