scaling race car cost

[truk]

ive been racing my truck for a few years and never had it scaled .i would like to have it done but dont know the cost . i called a couple of places one said 700.00 the other said 100.00 they would help with adjustments after itook it to track. what is every one else paying ? jsut tring to be informed. thanks matt :D

[truk]

well i guess no one has ever scaled there race car !!! lol

[mcracecars]

one of these days im going to get me a set of scales and charge $700 bucks to tell guys what their car weighs on each corner.... :shock: :lol:
each car is different on what the ideal corner weights are, but the whole idea is to give you a starting point to tune your chassis. You can also get the cars center of gravity from this.
Stock car guys have been doing this for years, and the big boys in drag racing have been doing it more and more.
$700 bucks seems high to just scale the car, and $100 bucks seems very cheap.
If you just want to see what the car weights then $100 is ok.
Why do you want to scale the car, are you having problems with it?

as an edit here, I see summit has 2 sets of scales, about $1050 and $1400. Get that $700 guy to scale twice and you could have bought your own set.

its a 125inch wheel base truck, 700hp eng, it just doesnt leave right . it goes straight every time ,doesnt seem like it tries to pick up the front end at all. ive had the 4link in every hole thats there and it dont seem to change alot. had converter rebiult, trans, 60fts are 1.38to 1.40 runs 977 at 140 in 1/4 . maybe just need bigger engine . lol thanks matt

I bought my scales from RJ RACECARS they use to sell them for $480 , there a mechanical type of scales , they work fine! $100 is ok for just corner weights , $700 is HIGH for that , whats the frtend setup in the truck? (shocks, springs ) could deffently be cause !!!

struts, full tube chassis with 4link ,strange struts

I was quoted $250 from a Chassis shop plus if we had to add weight I would have to pay for that also.

I have scaled all of my CARS...digital scales..you would be amazed at how much a 1/4 flat turn on the top pre-load bar will have you very heavy on the right rear...i would say if you could have somone with a digital set of scales that KNOWS what they are doing to scale the car out WITH YOU IN THE CAR...there is a difference of opinion with front to rear weight percentage.. 49/51 % is where my camaro scales out....your car will fall into its own percentage with how is built,,placement of motor etc..but this can be manipulated by adding lead pucks to whereever you choose to place..normally in the 2nd half of car.

you also want the car to weigh somewhere in the ball park of 10-15lbs heavy on the left rear when you scale it..WITH YOU IN THE CAR..

I AM NOT A CHASSIS BUILDER ETC..but i have been there with my chassis guy when the car was scaled and set up.....i had to be cause they have to weight the car with you in the drivers seat or at least place some weight in the seat that is close to what you weigh..but even that will not be distributed in the right places..

i do not think you would want much of a wheel stand would you ??..unless its for show.....but if you want a wheel stand or work it going toward that way i am confident the area's below will work you that way in a hurry

1- front to rear weight..heavier in the rear...example: 47/53 %....adding weight in the rear will get you there and it will not take much to tip the % scales that way.in other words it doesn't take 200lbs to move a few percent..think of it as a wheel barrow on a fulcrum..it doesn't take much force to tip the wheel barrow on over once it gets that way..maybe this was a poor anaolgy buy i think you get the point.40 lbs in the right spot will make a huge difference to your percentage if your close..it did in mine...

2- proper wheels weights....with coil overs you can make a wheel heavy or light...we have my left wheel pushing down ( heavy)

3- instant center.....different on every car cause 4 links are made different. this is the intersection point of your bottom bars and your top bars...this will determine greatly if your wheels are coming up or not.....( please print and read 4 link basics posted at the begining of the chassis section) ..much good info there in my opinion..it will go into thi more in depth..


i will assure you ..that if you manipulate these 3 areas to lean toward pulling the wheels..you will get it..unfortunatley the people i have been around that has done these wheels stands are caught off guard when it happens and its causes a MAJOR wheel stand and destroys a lot of stuff..

thats what a person gets when they blindly go turning a pre-load bar and starting moving the instant center without knowing where they stand to begin with...

so with all that said..i think it would be a wise investment for you to have the car scaled but only with qualfied chassis person that can help you with squaring the car properly,setting pinion angle,wheel weights and instant center point..

i hope this helps you decide on which way to go..

thanks brian

Invest in some wheelie bars are you may do something you where not planning on like Brian said. Wesley

[slowman]

were do you live truk i have scales and if you do all the work you can scale for free. i'm not a chassie guy and suck when it comes to figuring out the chassie but i have scales. bjuice is right you don't what to pull a big wheelie it has cost me thuosands of dollors over the yrs doing stupid shit like that. about a foot no more and that will sit on the rear tires hard.

[mcracecars]

I suppose I should have expanded a little more on my above post. These other guys have made some good points.
Ajustability in a race car is what we want, but too much can be a bad thing if you dont know were you are going with it.
So you weigh the corners and find all the bias and center of gravity etc, now what, were do you go from there?
This is were a good chassis guy can help you out.
some advice here would be to get Dave morgans book, at the least. Also good is the one from Jerry Bickle. Print out and read several times the above sticky thread on chassis tuning. These alone will get you in the right direction.
You can get yourself in a lot of trouble changing things on a car without knowing why you are doing it.

WE FORGIVE YOU!!!!!---DO YOU NEED A DEGREE TO SETUP A CAR!!--I'M SORRY THAT IS ANOTHER POST :lol: :lol: ---I LEARNED TO ALWAYS TAKE SMALL STEPS AND RECORD EVERYTHING I CHANGED SO I COULD CHANGE BACK IF NEEDED---MY 10 CENTS WORTH!!!!---GOOD CHASSIS GUYS ARE HARD TO FIND / WHEN YOU DO THEN LISTEN AND LEARN :D :D

[mcracecars]

Some good rules to follow, i found over the years...

1) dont p*$$ off your engine guy :?
2) dont p*$$ off you tranny guy :shock:
3) dont p*ss off your chassis guy :lol:

[lively]

TRUE WORDS!!! BUT YOU NEED TO INCLUDE THE BODY MAN[HE CAN REALLY MAKE YOU LOOK BAD] :lol: :lol: :lol:

[topsportsman1]

And lastly
4) Don't piss the moderator off :P

[lively]

YES YES YES SIR!!!!!! :lol: :lol: :lol: :lol:

[truk]

ive got the bickel book and read it alot but can get confusing, also have rj book, would like to find a good chassis guy around dayton ohio, advanced chassis is 2.5 hours away. i think thats is who will get the job. thanks for the advice.

[mcracecars]

well, im about 6-7 hrs away from ya... :D
you need to reread the book several times, and visualize what the car, or truck as you have is actually doing...
most of this stuff is the high school phisics and geometry with some math thrown in. You know that stuff that we saw no use for back in high school :lol:
any questions just ask away, lots of knowagable people on this site

hey maybe ill take a mini vaction to canada!! if i can get thru customs .lol

[mcracecars]

hey maybe ill take a mini vaction to canada!! if i can get thru customs .lol
Dont worry about Canada Customs, those guys are not allowed to carry guns... :lol: They may yell at you to stop in french however.... :shock:

[topsportsman1]

Only in Canada,you gotta love the canadians :P

[bjuice]

hey maybe ill take a mini vaction to canada!! if i can get thru customs .lol

i just got a good look at your truck picture,,and the way the thruck is laid out with the wheel base and the height of the car along where i think the motor sits..you gonna play a hard tim, getting that front end to stand up..its long,low ( center of gravity is low) built truck..my 67 camaro is the same way my 67 CAMARO is set up and its the devil to pull the front tires. but not as long as wheels base as you have..

if you get those front tires to stand please tell me what adjustment you used..i will be surprised if they do. this is a good thing also.

thanks- Brian

[truk]

yea i know wheel stand is not good ,just a ego thing i think!!!lol

[bbb555]

$700 is crazy high..

[raz1056]

Heck with wheelies, my car was scaled and leaves hard, goes straight as an arrow, runs 9 teens at 147 and it might pick the front tires 2 inches leaving at 4500.

This night of wheelstanding and slam dunking the oil pan is costing appx $4000.00 in engine damage and car damages.

This is not my suspension work.
IT is not my suggestions about suspension adjustng.

This car weighs 3046 lbs and has 52% on front and has 48% on rear. This is so called professional chassis baseline from a big name shop on the second attempt. Their first attempt was the car dead hooked hard. busted two sets of wheelie bars. broke high dollar heim joint, busted anti-roll bar and messed up the front end when it came down.

Thir first atempt was a too short and too high of IC. Their second solution was in thier words. "Maybe that engine is meaner then I thought" " Here that adjustment should keep you out of trouble" Their second solution was to move instant Center far forward and even higher than it was.

My only contribution to this funny froggy night is that I built the engine. It is one of my engines.

Froggy Vid was with long high IC.

[mcracecars]

Ed, why didnt he get into a 3rd time..... :shock: :lol:

[woodsman]

Texas Ed I think I have seen that car at Houston Motorsports track the same night that All Jacked Up had his wild ride at the track. Where you there. Wesley

[edvancedengines]

No. I am appx 300 miles North. In Plano N. of Dallas.

That night a good friend of mine Mr. Billy Stocklin and a friend of his Mr. Kenny Hubbard were helping a little and they took some hit out of it for the next pass attempt. Ended up with another Froggy. Then Billy had Kenny to take a lot of launch timing out and according to him it didn't jump right up but at 150 ft it was 4 feet and climbing headed for the wall, so Driver slam dunked it one more time. That did it in. No oil pressure in the pits, $1000.00 Oil Pan crushed into the pump. Both tie rods bent and front end messed up.; Ooops' . Engines running with no oil don't work very long.

I will likely by about 98% be at Evadale N. of Beaumont on the 21st of July for the big East West True 10.5 and Outlaw 10.5 plus Match Race Madness Shootout though. Possibly that car and another of my customers will be there doing some Match Racing.

It will all depend on if the guys can get the money to finish their stuff up. Both cars will need some T-N-T somewhere else before they run there. I told my customer I don't want that car (Tony's Tiger) at HMP again unless he is ready to run a number and light up the clocks. They have a few scores to settle before they will light up the clocks in Houston or do any full passes in Houston. Now they are listening to me over the phone, so hopefuully we can get some of that frog out of it. I am planning on finishing the engine again this month. Going back with exact same pistons too.

Ed

If you come, ask one of the Promoters on the line where I am. They are both customers of mine.


Here is the flyer for the race. IT should be big. We have commitments from West Coast Record Holders and East Coast Record Holders, in the Drag Radial calsses. They are putting 10.5 's on for the race. Artis Houston and Tim Rigby from Calif are coming and bringing others. David Reese from Florida is coming and helping to organsie this. T-Berry or Todd Berry Motrosports with Eric Dillard are coming. THree of those cars are record holders in their classes. IT should be good.

Ed we will be back in the country an mama said that we will go to a car show in Kerrville an then head to Evadale. So will do our dead level best to be there. Because that don't sound like something to miss. Well if God willing and the creek don't rise I will see you at the track. Wesley

[excelerater]

I borrowed a set of scales as I made a ton of changes to my car's
weight and ended up 52 front 48 rear which is pretty good for a GBody.....
I made a few adjustments which showed on the scales
but once you bounce the car a few times the readings changed anyways

Its a nice tool to use or borrow but hardly something
I would need a chasis shop for and spend 700 bucks for .
That guy is asking 700 bucks
is ludacrus since a set costs only a little bit more...
