Golf R -v- Golf GTI

[dave_r]

Have your thought about putting a small hole in the sump, so you can get the true GTI experience of wondering where all your oil is going?

They might be onto something though, probably save a good 5kg over the front axles by running dry

Actually, it's strategy that occurs in some forms of motor racing all the time. Not filling up the motor, gearbox, and diff oil completely. Not only do you save weight, but you reduce the drive train loss as the gears/whatever are "slapping" the oil bath rather than pushing through it (think of it as the difference between moving your arm touching the surface of a pool compared to underwater in a pool.

Of course, it's a risky thing to do, cause fill it slightly too low, and the parts aren't getting enough lubrication. Thus, it's mostly utilised only in qualification...

Same reason why you only fill up to 1/4 of a tank for the drag strip, easy 40kg weight saving there.

..... mainly in differentials and gearboxes as dry sump set ups are pretty common.

Don't forget to prod the rattlesnake on the passenger seat when taking off to simulate the actuator rod...

Here we go lol.....

wow...a dry sump - no oil at all...imagine how much weight and wastefull splashing that'd save.
Spare me, please.
kids say the darndest things

Really?

You can't be that stupid....

[ethosguy]

Really, dry sump, don't you use light weight graphite powder in place of oil???

ummm, no! Well not usually anyway, I hope.

Nor would I suggest to run quali laps with low oil level to save weight and reduce oil churning power losses as an earlier post suggested by the inuendo'd 'kid'.

Competition work usually sees an increase to oil volume to protect against so many heavy use issues I couldn't help myself.
Too subtle it seems. Oh well. next time, maybe?

[Corey_R]

Well ethosguy, no disrespect or anything, but unless you're actually Gordon Murray or something in real life, I suggest you have a look at who Chad Knaus is, cause I'm pretty sure he knows better than you

Having said that, you sure wouldn't want to be doing that in any normal car at all, and you sure wouldn't want to be doing that in even a race car unless you reaaaally knew what you were doing.

[dave_r]

Corey do you pull out wiki's and useless facts when arguing with the missus? I reckon eventually it will be like an episiode of Chappelle's "When keepin it real goes wrong", make sure you youtube it!

Yeah, the EA888 is simply not suitable to real high performance applications. APR are seeming to get away with it on their Stage 3 GTI that they've used for the past few years, but I'm not sure what lengths (and costs) they've gone to to resolve the "oil issues" in the EA888. Whilst others have said that Volkswagen will fix the EA888's oil issues with time... they obviously are not confident with it yet as they put the EA113 in the GTI Ed 35!

I wouldn't know the entire reason for not using the EA888 but I am of the opinion that due to some issues with the EA888 they decided to use the EA113 engine for these cars because it would cost less time and money to build them.
So basically VW really just wanted to increase their profile of golf cars in the shortest amount of time and at less cost. I think we all know that VW has major issues with their production lines rolling out the premium golf models in a reasonable time for certain markets. VW will go on to resolve the oil issues or whatever issues there are one would expect.
However having done 15000kms on my GTI, I would never go back to a less refined older engine.

lol... how would you know the difference

Can someone explain what these oil issues are.
