McLaren have gone through a difficult season, but a proper look at their new MP4-31 suggest they have put in considerable effort to come back from that swiftly.
Very strange, lap time to fast maybe? Wishful thinking I know.radosav wrote:Found this on other forums, the guy who recorded it says Fernando on last day of his test did this many times. He would take last corner very fast than on straight he would slow don on dirty side then accelerate again.

They might not have been able to risk running the PU to it's full potential for a reason! so for that reason I think we can safely assume they do have some time in the bank. I am going to say they only had one of the updated PU's so for this reason didn't want to push it to hard and break it, they wouldn't have gained any useful data. I am purely speculating, there could be another reason....?dot235 wrote:enkidu1978 wrote:Very strange, lap time to fast maybe?

He's testing acceleration and/or traction most prob.

I'am curious why McL haven't really done a competitive lap. I know it's just testing, but it still very much has commercial side to it. Being at the top of the table after such a terrible season would do them only good. And it's not like sandbagging will do anything good for them either. I mean, they aren't fighting with Ferrari, Mercedes, Force India or Williams regardless... So what's there to lose with doing one low fuel full beans lap on US?
Last year all teams had converged on the minimum allowed exhaust diameter, suggesting that the ideal diameter would be even smaller. This might be a way of going effectively below it. Clearly (to a point) back pressure is giving them more benefits than trouble.Steven wrote:Quite interesting that they apparently found that such a big piece inside the exhaust pipe isn't a problem in relation to back pressure on the turbo charger..rccrdc wrote:
Maybe not back pressure as much increasing exhaust velocity offering more aero advantage for the upwash they're utilizing?hollus wrote:Last year all teams had converged on the minimum allowed exhaust diameter, suggesting that the ideal diameter would be even smaller.

Wondering the same thing. Probably it was what others mentioned, they had no actual mileage even from 2015 so they decided to do as many as possible to get valuable data and then start pushing. However, if something goes wrong in-season and they start blowing engines this is gonna cost them. On the other hand, I was expecting them to push the car hard at least in last day of testing, with a good amount of laps under their belt so not to get hurt a lot by a possible engine blow. Maybe they are heavily sandbagging ? Something tells me though that by the end of the season they can be the 3rd best team.dot235 wrote:enkidu1978 wrote:Very strange, lap time to fast maybe?

EBD have shown that blowing the edges of a downloaded surface is more effective than blowing the center. At the center you just exploit the increased speed of the plume, at the sides you use that speed to stretch the side vortices. The monkey seat on Mclaren has no endplates, to allow the vortices to act on its lower surfacehorse wrote:https://pbs.twimg.com/media/CcskWS4W4AAztKy.jpg:large
In context, I propose that this is working with the monkey seat, spreading the exhaust plume over a wider operating surface.
Diffuser : The vertical strakes (the left bank, marked in yellow) which align airflow within and assist in creating the diffusers volume in yaw have been amended. Their shape and angle have been slightly revised but more importantly rather than falling short of the diffuser trailing edge, they now meet with it.
The waste gates are also restricted so maybe they are trying to create some kind of additional stress and verfied the reliability of the system.hollus wrote:Last year all teams had converged on the minimum allowed exhaust diameter, suggesting that the ideal diameter would be even smaller.

Or simulate a track with a slow last corner folowed by a long straight.Joseki wrote:Maybe he's slowing down to 100 km/h, the minum speed requiered to activate the MGU-K, to check the MGU-H to MGU-K deployment. Or maybe I'm wrong.

It was originaly reported 8 laps....and Jenson 1.25.200 (soft) a 10 laps stint, but now Benson is saying it was 4 laps for Alonso?
