Destructo Report post Posted December 10, 2015 Are you on a dyno? I can only imagine with that speed and "not enough air flow" in that circumstance to be on one to get that warning. Quote Share this post Link to post Share on other sites More sharing options...
AudiBull Report post Posted December 10, 2015 Next thought that came to mind was aftermarket wheels or worn tires (rears more worn than fronts). What's the setup? Quote Share this post Link to post Share on other sites More sharing options...
Sal Report post Posted December 10, 2015 Wrong tire sizes would change the factory rolling diameter required for the Huracan... When changing wheels or tire sizes on an AWD vehicle. You must keep as close to the same rolling diameter as factory tire specs. I not sure of the exact + or - tolerance allowed. Otherwise you can cause damage to the AWD system ( I believe it is the viscous coupler or apex) and possibly void your warranty.

Yeah, i believe some Murcielagos had some issues when people put shit wheels on them that were looks only and not the proper spec. I can't recall if the Aventadors had the same issue.

Assman Report post Posted December 10, 2015 Yeah, i believe some Murcielagos had some issues when people put shit wheels on them that were looks only and not the proper spec. I can't recall if the Aventadors had the same issue. Not just wheels, even tires. To the OP. 4wd overheating means you're going to buy a new front diff if they don't cover it on warranty.

VentadorGER Report post Posted December 10, 2015 This is a screenshot taken from an acceleration video from 0-340 Km/h done by a German Magazine called "Auto-Motor-Sport". They used Trofeo R´s with 235/35 R20 and 305/30 R20, so the front tire size was way larger than the standard 245/30 R20. They used them because the Trofeo Rs werent available in the correct sizes yet Quote Share this post Link to post Share on other sites More sharing options...

They used them because the Trofeo Rs werent available in the correct sizes yet Based on the above data and assuming both tyres were new, according to tire rack specs, the AWD rolling diameter front and rear difference was 3.0%. This is less than the maximum allowable difference of 4% for Audi /Lambos, so front diff should not have overheated. The speed shown is a touch optimistic as oem speedometers over read from my lambo/audi experience by about 3%, so more likely 325 km/hr, the gps top speed for a Huracan. Just my two cents worth, cheers, john Quote Share this post Link to post Share on other sites More sharing options...

I was just mentioning that many magazines at that time were provided with a Huracan equipped with Trofeo R´s in that size and that might have caused it.
