old school hot rodding tricks

Putting your motor mounts on backwards on a small block chevy to move the motor back to the firewall and then have to beat a dent in the firewall after you broke the distributor...:biggrin:

Making swiss cheese out of the front frame.
 
Pronto & myself use to buy CLOROX or steal it from my moms washroom.

We would take my Dad's Montego MX a few towns away and go to the roads that connected the sand pits.

This was the place everyone went to lay wads of rubber.

We would put bleach under each tire & PILLOWS of White smoke would bellow out of the wheel wells & into the back seat.

Dad kept wondering how his tires kept wearing out so quick.
 
My favorite story is the guys who filled their tires with helium and put helium-filled kiddie pools in the trunk to lighten the car.

mythbusters took on the "helium in the tires" thing and saw no noticable loss on wheel/tire weight or any affect on acceleration or fuel economy.. i wish they'd do one about nitrogen filled tires..
 
I read about the helium deal in a Hot Rod mag article about some of the craziest things hot rodders had tried. LMAO and have never forgotten that one.

I'll look to see if I still have that mag and post up some of the others.

Dry air is 78% nitrogen to start with and my only first hand experience with the nitrogen system is that it is BS. My new wife's son had put a system on her Pathfinder and the low tire light came on and she went to a local tire shop and they told her that she would have to pay them about $80 for them to fix the tire, refill it with nitrogen and reset her system. I called my good friend at a reputable tire shop and she took the car to him, he fixed the tire and re-inflated it and the warning light disappeared when the tire was properly inflated. $80 to fix a flat; damn, I'm in the wrong business.

Got this Consumer Report off Google:

Tires - Nitrogen air loss study

Filling tires with nitrogen rather than air is becoming a common practice in the replacement tire market. This service offers tire dealers another avenue for making money while also promoting safety. The claimed safety benefits often include the potential for reducing air loss compared to an air-filled tire. Maintaining proper inflation can help prevent tire overheating; promote optimum tread life; and reduce rubber aging and wheel corrosion. The use of nitrogen in large truck fleets and the commercial tire industry are well documented and support these claims.

The National Highway Traffic Safety Administration (NHTSA) has seen reduced aging of tires filled with nitrogen. Though the data does support that passenger car tires could benefit by all the claims made for nitrogen, tire manufacturers say that they already design tires to perform well with air inflation. And while nitrogen will do no harm, manufacturers say that they don't see the need to use nitrogen, which generally adds $5 or more per tire charge.

Consumer Reports wanted to find out if nitrogen is worth the price, so we purchased a Nitrogen Inflation System and checked out how well the inflation held up over a one year period. We evaluated pairs of 31 tire models of H- and V-speed rated, all-season tires used in our tread wear test from 2006. We filled one tire per model with air and the other with nitrogen. The test was quite simple: fill and set the inflation pressure at room temperature to 30 psi (pounds per square inch); set the tire outdoors for one year; and then recheck the inflation pressure at room temperature after a one year period.

The tires were filled and deflated three times with nitrogen to purge the air out of the tire cavity. We also used an oxygen analyzer to be sure we had 95-percent nitrogen purity in the tire--the claimed purity limit of our nitrogen system, which generates nitrogen gas from ambient air.

The test started on September 20, 2006 and the final measurements were taken on September 20, 2007. The results show nitrogen does reduce pressure loss over time, but the reduction is only a 1.3 psi difference from air-filled tires. The average loss of air-filled tires was just 3.5 psi from the initial 30 pressure setting. Nitrogen-filled tires lost an average of 2.2 psi from the initial 30 psi setting. More important, all tires lost air pressure regardless of the inflation medium, so consumers should check their tires' air pressure routinely. No evaluation was done to assess the aging claim.

Bottom line: Overall, consumers can use nitrogen and might enjoy the slight improvement in air retention provided, but it's not a substitute for regular inflation checks.
