Here are some I can recall..
- Cammed wing flaps that slide and flatten at high speed (sufficient downforce and drag), but that don't flatten under a simple deflection test (downward force only).
- Elastic or hydraulic connecting rods
- Reground stock cams to smaller base circle for more lift
- Camber cutting/forming tires (solid axle)
- Growing tires (gearing rule), treating tires, etc.
- Bending sharp edge orifice restrictor plates very slightly around the orifices with a hard ball and a hammer
- Intake manifolds full of tiny precision laser burned holes. Later uncovered by colored fuel showing on manifold exterior.
- Nitro in oil with breather venting to intake (4 stroke)
- Nitro in oil (2 stroke)
Let's hear more
BTW, how DO you get around venturi type restrictors? There are so many classes that run them, in addition to SEO type.

Thanks, I had heard and forgotten about the scaled down car and the coiled fuel line, hahah.
Thanks for the link Dallas, do you know if there's a detailed diagram of the described system anywhere? I have a rough idea what they mean, but would like to see exactly.. especially the portion about the hose, clip, and catches.

Desmo, I think this was Tyrrell, who were caught allegedly topping up their cooling water tank with water that contained lead shot to bring the car back up to weight. Ironically the team was purchased by BAR who went on to have ballast problems of their own.

It was Tyrrell, but the ballast was perfectly legal as the regulations allowed it to be added if you could not remove it from the car without the aid of tools. Which you could not.Originally posted by Dallas84

Plus FISA disqualified Tyrrell at the final hearing having changed the charge - instead of ballast they said there were hydrocarbons (so they had been illegally topping up with fuel). Although the level of hydrocarbon kept changing throughout the hearing and eventually it seemed that any hydrocarbon was leftovers from the water churn's previous fuel-carrying life.
Other things include the Brabham very heavy rear wing, that used to get placed on the car for weighing purposes, the water-cooled brake controversy in early '82 that indirectly led to the death of Gilles Villeneuve, turbo engines and a Lotus mechanic leaning on Jochen Rindt's rear wing at the British GP 1970 to ensure it was below maximum height (although it turned out that the measurements were wrong and it was always legal anyway).

My Smokey favorites (of those not mentioned before in this thread):
Rule: No machining allowed of the intake.
Response: Extrudehone http://www.extrudehone.com/
Rule: Minimum ride height checked by sliding a pipe with a diameter equal to min ride height under the car.
Response: Had mechanics standing at the ready to help inspectors ... the car was parked on their toes, until Smokey pissed off an inspector and the inspector shoved one of the mechanics away from the car ... the mechanic got a bruised bum. Smokey's response was to put rows of aspirin tablets on top of the springs. The car would pass tech inspection (which were then only before the race), and as soon as it hit a bump all of the tablets would shatter and the car would drop.
Smokey, and I think most F1 engineers, felt that there was not "spirit" of the rules, merely how they were enforced. If you can get around the enforcement then that was the fault of the enforcers.

Apparently another trick of Smokeys was to lift the car up on its springs to the legal height clearance to pass over the inspector's gauge and then freeze the shock absorbers with dry ice so the car stayed at the legal height long enough to be cleared.

I don't know if I completely agree. Did you ever read his books? He did most of his 'cheats' by going against the spirit, but not the letter of the law. That is different than 'getting around' the enforcement. I'm not an F-1 engineer, but If I wanted to see how far I could get around the enforcement of a certain group, then I grant you I could go very far indeed.
And what does that get you? Now you're known as a cheater and all your wins before and after are tainted even if they are completely legitimate. I like doing 'clever' things that are not mentioned by the book, but I think that people who just disregard a rule are ****.

Well, the Germans built these huge warships with massive cannons and massive armor. They then just filled out the paperwork that said they were of the proper size. It's a ridiculously simple cheat, and not really clever at all, but the audacity that it took to pull it off was impressive none the less.

There was also a discrepancy in refueling related to the actual fuel capacity of the car, but it doesn't appear to have been used for competitive advantage.
There is no way to prove it now and the principals involved will never admit it, but a number of people fervently believe the 1969 Indy 500 was won with an oversized (255) engine.

If that's the case, then 1981 and hell, every other time he was there makes my point. There's a weird karma thing that goes on. If you cheat it always seems to come back and bite you in the ass.

That just dawned on me that you were talking about AJ and Dan....well, Dan, since he drove about 22 hours.
Of course it was cheated up. Dan called it 'Pioneering'. His sons and I cheated the hell out of a go-kart in an endurance race and had a ball doing it. I think we finished 9th out of 11 finishers. Just for the record, there was no money on the line and we were complete idiots about it. Obviously we didn't do a very good job.

I agree with you 100%. Smokey could not stand the rules enforcement style in NASCAR or the people in charge of it, and he didn't much like Bill France's ways either. In his mind he was screwing with them because they were screwing with him. However, over at the Indy 500 he ran everything straight up and wouldn't abide any form of cheating. To him the Speedway was hallowed ground.
I will also add that I believe Smokey never cheated as much as people thought he did or said he did, or as much as he liked to suggest he did. Over time the whole thing has become a sort of urban folklore.

Not true. In the middle of the night Dan, knowing the ropes, hid out and Foyt had to drive a triple stint.
Except for running out of gas once (not his fault) AJ never put a wheel wrong, and the two of them ran the thing like a freight train. Everyone believed Gurney and Foyt were supposed to be the rabbits, but they cruised while everyone else crashed out or broke.

Oops. He and his driver Jerry Eckman were made the goats and then everyone moved on.

Innovation not specifically outlawed in the rules is where Smokey lived, and I don't think he, or most of his competitors for that matter, called it "cheating" although they might call the parts "cheater parts".
The NASCAR fuel limit is a good example ... the rules said the fuel tank capacity could be no more than X, but the rules didn't say anything about the rest of the fuel system ... until Smokey showed them they needed to refine their rules and their enforcement.
Smokey was abrasive, brash, inventive, brilliant, hated, and loved in the pit lane by most accounts I have heard/read.
I think one of the reasons Smokey's exploits have become folklore is that they were so briliiant that the few there were are blown up to bigger proportions.

Or, can you freeze them, just so that there is no ice buildup, and then feed some chilled air into them from the newly ACO-mandated A/C? Sorry that my thermodynamics is so 101, but if PV=RT, then for every 1 deg K of a drop in the IAT, would we then get about a ~0.34% increase in the volumetric efficiency? About 2 HP for a typical 500-600 HP racecar? Is this math any close?
Of course the A/C consumes a lot of power too, so it should only be run in braking zones and in turns. I cannot tell how effective a typical A/C system can be in cooling the huge amounts of the intake air. Probably not that much. But if someone decides to try it, send me a private email, so that I could later write my own cheater's memoirs!

Every try to track down a pesky vacuum leak?
Anything that creates a vacuum leak is a cheat on the intake restrictor. Porous intake manifolds, hollow bolts, tricky gaskets, angle milled parts...the list is endless and in NASCAR they have about tried them all.
In endurance sports car racing there is not much point in cheating another 10-20 hp. Certainly not worth getting caught unless you are desperate. But on an oval 20 hp might be the whole show.
A funny story... at LeMans in 2000 I was standing in the paddock talking to the head of a factory motorsports program. Behind him over his shoulder the crew was starting one of the cars. It was sounding kind of funny when the mechanic realized he had not removed the boot from the air intake. He quickly jerked it out and then started furtively looking around to see if anyone saw what had just happened. I just kept looking straight ahead at the manager, trying to keep a straight face.

Again, not a true cheat, just people being clever. They simply passed high velocity air right in the path of the pop off valve sensor. Bernoulli said that a high velocity fluid has less pressure than a low velocity one. The measured pressure at the sensor was what was used to control the pop-off valve, but the actual pressure at the intake trumpets was higher.
When you start getting into these areas of the rulebook, either everyone has to do the same thing, or the rule makers have to start 'spec'ing' parts. CART's approach was to change the way the pressure sensor was mounted to give a more representative pressure reading, and Honda through a fit.
In the end, Champ Car has spec'ed the entire engine package. That really makes for the best racing anyhow.

That was like putting the foxes in charge of the henhouse. Big mistake. The rules enforcers must be totally independent, merciless and arbitrary.
