Rally Cars tech stuff

[dupanton]

It was with a car from Belgian championship, I don't know exact regulations for the fuel - if they use their own or how it is. In the national championship I think the risk of running out of fuel isn't that big as the loops aren't that long but anyway he told me the consumption was some 20% higher.

In the Belgian Championship it isn't allowed any more, in the Netherlands it is used a lot in Nissan 350Z's and Evo R4/N4's.

Interesting pics of the Skoda Fabia S2000 powertrain and chassis.

Looking at the second pic from left, the attachment points of the suspension arms to the upright/wheel hub are at very low point. Must have something to do with the suspension geometry. Is this a tarmac suspension? Looks like it would be very vulnerable on gravel.

Fuel consumption 0,60 l / km SS (60 l / 100 SS km)

Really good find! Nice details in the photos.

You are right about the suspension arms attachment with the upright, they seem to be unnecessarily low but they should have their purpose. Surprisingly, it seems it can accommodate even longer shock absorbers (at least at the rear).

Yeah that's clearly a thing to correct roll center when they go low for tarmac...
Lovely detailed piccies, wish we could find equally nice picces of the other cars..

Thanks vurpan, you have earned your Kossu.

Sometimes Google give some answers. The third pic is the answer.

Kiitos Gamle Finne..you know I manufacture suspension mainly gravel but in America every boy under 30 has compulive disorder which makes the feel they have to lower their car 100-120mm so their car is like this, so I have made things like that to correct the position of lower arm when using short strut.




Very hard to deal with silly boys who have mental disorders. Facts don't help, reasoning, drawings, nothing helps..

Sometimes to help understand I use teacher's aids like this:
First you point out the components or idea:


Then you impress on them how important the idea is...



with rally boys it usually takes a couple of times: (especially when they are "injur-near" and their name was originally "Håkansson" before it became "Hawkinson" and then I ''döpte om dom'' to Hoikansainalainen ---all rally drivers must have a Finnish name to channel to spirit)

That's me doing the technical instruction....over here i"m one of the "Old FARTs" (Flemish-American Rally Team)

So that´s Your Ecellency "i egen hög person" in the picture, trying to learn out some behaviour?

Jo, erkänner.

To keep this to rally car tech stuff here is us installing nice B23 turbo motor for our 2wd turbo class into that nice 240... Nobody pushes Volvo 240 harder in America (which is a bit odd for a Ford guy, eller hur?)
(Sanningen är vi fick aldrig Escorten dvs rwd Escorten härborta, så 240 är Americas Escort, men större så det passar våra SS som är ofta som Autobahn)


We bad. way bad
(I'm the old guy with his ciggie...maybe 5 years ago.)



One of ''our'' version of Sierra in backgrunden (came with a Ford 2300SOHC nearly identical to Volvo B23 but all IRON!

[Rallyper]

So cool! More Volvo-fans here in Sweden should know about your work over there. As you probably already know there´s a lot of turbo-240/740/940´s here, rebuilt by youngsters with power train illness...

Most 240s that aren't rusted to heck seem to be in the Northwest of the country. I had a coworker defect to work for Case IH in Portland who says they're everywhere. I'd consider getting one myself but this Subaru just won't die.

And in regards to those Skoda pictures (fifth from the left), are those ball bearings on the wheels? Most stuff (okay, my Subaru again) uses needle bearings, though it does look like the rally car's got two rows of sealed ball bearings, like a skateboard.
