I recall a few years back Toyota were BANNED form WRC for at least one full season (1 year). Huge news as at the time they we're winning everything.

The turbos on their Rally Cars had the 34mm restrictor fitted, but they had found some way of by-passing it, with a "trick" turbo design - it was deffo ileagal - as Toyota did not even apeal the 1 year ban.
Anybody know how the "trick" turbo was done?? Any pics/cutaway drawings etc???

Have wondered about this for ages..........

Also, any other "big cheats" in Motor-Sport
storys that peeps can post up?????
======================================

another top post naughty buggers but very clever if your not cheating your not trying hard enough

 

Interesting to read the in's & outs about the turbo

Looks a top site aswell

 

I remember this at the time... smart peice of rule bending!

alex

 

Very clever

Good site too, loads of good shit on there.

Called Shalco too, i know someone called Shalco...

 

Thanks Bill

Makes me wonder if any current WRC teams are using even more clever
tricks that really are totally impossible to detect

 

Cool site! Nicely engineered little cheat by the sound of it!

So what other motorsport engineering cheats do we know about?

I remember reading something about Lancia having hidden Nitrous on one of their 80's rally cars at some stage, or did I just dream that? dunno.

steve

 

I wonder if anyone snitched on them, or if it was a hardcore scrutineer?

Henry Toivenen died allegedley trying nitro on the Lancia Delta S4 Grp 'B' car....everyone sort of stopped with the nitro after that....then of course they banned em and went back to grp A....

 

Rule bending is rife in both racing and rallying.....you only have to go to an international event and watch the grp n cars going through scrutineering....the cars sound really docile at scrutineering....quick ecu and exhaust swap and hey presto a showroom car that can perform as well as a grp 'a' car....at the time toyota got banned people even at club level in the u.k. were swapping restrictors on road section etc.....that's why now the fixing bolts have to come right through the compressor housing....still the most unfair thing in club rallying we have to run restricted cossie's but you can legally run a 450 bhp metro...

 

Um....NO

Toivonens death was a result of a HUGE crash that was attributed (most likely) to the amount of medication he was taking to combat a bad cold/flu at (IIRC) Corsica. He left the road at full chat (no skid marks were evident) and apparently unconscious. Both he and codriver Sergio Cresto were killed in the accident. There was not much left of the Delta S4.

Nitrous is not a viable prospect on any racing car due to the weight of the bottle, even if this is countered by removing weight from elsewhere the nitrous just doesn't last long enough to make it worthwhile. Espcially in group b rallying, more power was the least of their worries!

 

What if you used the hollow rollcage structure act as a canister to contain the compressed NOS gas? Well hidden and no extra weight. OK thats what I heard, but I'm sure its just an Urban Legend.

steve

 

It didn't help that the S4 stored fuel under the seats to keep a low CoG. I think Henry ended up upside-down suspended in trees (fuel now directly above them) and died in a fireball.
Wouldn't want to drive an S4 after a night on the curried goats head

Newts

 

what about if a carbon fibre bottle was used and oviously the more you use it the empitier/lighter it gets

 

group B cars has an excess of horsepower if a bottle of nitrous gave you 20% more grip they'd all have been using it but an instant +xxx horsepower (and only for short bursts) is not somthing you would ever find a worthwhile benefit outside of drag racing

 

Always get a lump in the throat when reading about Toivonens death,a true legend who died way before his time R.I.P

 

BTTT...........

BTW, any more cheats in Motor-Sport storys to tell ???????

Post up if you have please!!!!

=================================

 

Im sure Rapid1 could tell you how far back he was from the launch line when he managed a timed 2.99 0-60 if that counts

 

I heard that T4's are deliberately made laggy fookers by Garrett
to make the GT series look even better.
Thats what I call forward planning !

 

But Simon,

Read Mike Rainbirds pst about his T4 and the spool up and full boost at low (ish) revs and power/torque that he's got

Impressive to say the least - for a T4

I'ts on the "Is there a better manifold..." post, page 6 I think.

 

Doug Stirling, Seen it, perhaps Mike's tuner has found out Garretts "cheat"

 

If you speek to tony ryan , hell tell you about his loom ,

Apparently its a proper , P6 , L8 ( what ever the fook it is ) Rally loom .

Found a seperate connector on it , , was used to hide a map sensor, seperate ECU , or sommat from the scrutineers , 275 bhp through scrutineering , flick the switch and way hay !!!!!!!!!!!!!!!!!!!!!!

 

Remember reading about Trevor Parish and the Merc racing trucks.
They were restricted and tested, but he had an adjustable boost connected to the fog lamp switch.
Scrutineering - fog lights off, nice and legal
Race - fog lights on 100+ extra BHP

 

A similar one was performed by the amazing legend "Smokey" Yunick, during his career as car/engine builder in the NASCAR-series. As they run great distances with the car, refueling is a common thing. What Yunick did was to fill the rollcage with fuel as well after weighing the car in before the race After this they have a maximum allowed fuel amount, which is checked prior to every race

Another cheat performed by smokey, the man that doubled the size of the rulebook concerning layout of NASCAR-vehicles. The cylinder heads of the GM-engines was not allowed to be modified in any way. Inspection of the ports were taking place before every race. Well, Smokey wanted better cylinder heads anyway. What he did was to create a device, which pushed a mixture of water and sand through the ports, and gradually made them more ideal for flow. At first he just used it lightly, but gradually more and more, until the referees caught up on him bigtime! After that, the cylinder heads were given from the NASCAR-organization before every race

And a third one. This one is just too much Weight is of the issue of every race car. Thats easily understandable. All the NASCAR-vehicles were based on the same cars. Certain parts were allowed to modify, others not. Smokey and his team had lighted the car as much as possible, pretty equal to the other teams cars. But as always, Smokey wanted more and better. Ok, this one is way bizarre. At one competition, when they weighed the car, smokeys cars were incredibly light compared to the others. They started to get suspicious as always, around Smokey, but didnt come up with ANYTHING. Then they measured the dimensions of the vehicle... It was 5cm shorter on all dimensions! Nowadays, every car is measured prior to competition.

A bit from Smokey Yunick, a true legend.

 

pmsl at some of these little cheats ,

teh lancia did have nitrous , and it was actually stores in empty fire extinguisher bottles , hence no one knew it was there !


i agree ian , totally unfair ,

another restrictor trick ( ndont know if i should be telling this - is there any rac scrutineers on here ?)
is , for those who dont know , we have three cap headed bolts in a triangle formaition around the compressor inlet to hols the restrictor in , these have to be drilled and lockwired all together and then lock wired to the compressor , so they cant be undone , then a lead tag is fitted by an RAC official and the tag number noted on your rac log book, so how do you remove the restrictor bolts without breaking the lock wire ?






well you dont , whatyou do is , drill out the center of the bolts, tap them smaller and fit grub screws, so you fit your 3 bolts to the compressor and lock them off with nuts to the comp housing , then you screw in your grub screws enough to hold the restrictor in, after its been tested , small allen key past the lock wire, undo the grub screws and remove said restrictor , switch to full power map , and off you go 400hp and more torque to match !!



but shhhhhhhhhhhhhhhhh i didnt say owt, and no i havnt got it done to mine

 

quality

AWESOME

Makes me wanna go rallying

 

hee hee!
i love my GT4

 

I thought the .55 housing was an original Ford cheat?

 

I used to know a bloke who was on the Ford rally teams years ago, and he told me that ford used to fill the cages with nitrous and use it as a form of anti-lag.

 

Well, back in the day....

When I raced bikes, we used to wire the alternator field through the neutral switch in the transmisison. The bike would increase voltage when checked at tech with the trans in neutral, but once in the race, no power to the field and therefore no alternator drag.

The engine didn't MAKE any more power, but something like 3hp was gained at the wheel because the parasitic losses were less.

 

you cheating fookers!

I heard about the Toyota thing when it first came to light. Pretty much shocked the racing world!

Dave Brodie got done for using illegal fuel in the BTCC - Ive got a short 2 minute interview of him where he goes on to slag off to other drivers - big time!!! Ill see if I can find it
