IOM TT 2018 Car Lap record run?
Discussion
Don’t all the F1 teams have full simulators of all tracks and the F1 drivers practice in them.
Would be interesting to see the genuine lap times v the simulator. Then you have a tolerance to apply to the equivalent IOM simulator.
Clearly how you gauge the fact of you can die/kill spectators in the real world is very difficult to scale back the time.

The guy I have put up vids from has a series where using the same sim and equipment he tries to match pole times for this years F1 and generally gets within about half a sec so the sim part of it seems pretty close.
If the Prodrive Subaru can manage 128 average with 600bhp, yet it’s a car that’s 10 seconds slower or so then a GT2 RS around the ring due to its relative lack of grunt, maybe the Litchfield LM1 RS is the car to do it. 1000bhp or so, considerably lighter than a standard GTR, proper aero but suspension setup to handle the bumps of that German toll road... This thing should manage a higher average than the Subaru did, how much more who knows? You’d think it could manage a 130-132 average lap surely?Has it done a lap of the Ring yet? any idea on time?
Going on their video of testing its going to be a bit slower as in the section from Aremberg to Kallenhard the GTR is about 5 secs slower than the Subaru and Porsche. In fact I just had a look and a standard GTR is 2-3 secs faster than the Litchfield one, that's a bit awkward. So unless it can make up some monumental ground on the straights then I don't think its going to do it.

A car built for the job would annihilate the bikes, it's basic physics of what performance you can package and how much tyre grip you can generate.
The Subaru is a very limited package built for a PR exercise, in the big scheme of building a car for the job its slow.
The IOM circuit is narrow (and there are lots of things to hit which will definitely ruin your day).The Subaru is a very limited package built for a PR exercise, in the big scheme of building a car for the job its slow.
It's not all about power and grip. Bikes can take different lines and make the most of the available road.
If you look at some on-boards of the TT some of the speeds given the surroundings are bonkers.

makes the TT track looks quite wide, do you think any bike would beat 35 secs up there? (even taking away the standing start which would suit the car)

Some very narrow bits there - however there are parts that (in theory) id say a lot more time could be found. https://www.youtube.com/watch?v=9kufacVXlSc

Crazy speeds though no margin for error or bye bye

power rangers throwing a paddy when you mention "car" and "isle of man tt" in the same sentence
Funny isn’t it I guess as it’s literally the only track in the world (afaik) where the bike record is quicker than the car record they are a bit defensive.
I love the tt, and the skill/bravery of the riders is immense, however the footage of the Subaru laps is more impressive imo than the bikes.
I suppose the reason that there is no dedicated car day is that if one got it badly wrong it would take out an awful lot of scenery with it, but they let Higgins have a go as they trust him somewhat?

But as quite a few people have said now, the IOM is quite different to anywhere else.
I'm not sure that car would fair so well on public roads.
Impressive though. Ta.

Are there any places in the world where bikes and cars race on the same bits of tarmac (not even talking just circuits here) where the fastest bike beats the fastest car?
No, which is why a race car built specifically for the job by a major manufacturer would easily break the lap record (as lots of other people in this thread have said)RB Will said:

I know it wasn’t running full power or possibly even flat out at all last time it went over there, biggest factor may well be the driver more than anything else. If the cars prepped well enough stick Higgins in that car around the IOM and it should easily manage a quicker time, if of course Litchfield aren’t very publically just making themselves look a bit stupid...

One word:
DOWNFORCE
A bike doesn't use downforce, so the only force available to push it's tyres into the road is it's mass, that necessarily limits it's maximum G to around 1 to 1.2 g even on the softest best tyres ever made.
A car, and especially one not held back by any regulations can leverage downforce. An F1 car, which is enormously hobbled by regulations, can pull 5 g, as it can create 4 times it's own mass in downforce
5g is five times greater than 1g, and as Centripetal Acceleration is equal to the square of the velocity, divided by the radius of the circular path, that means our downforce assisted car can either corner 5 times tighter at the same speed, or take the same bend at 2.23 faster speed!
And as we have no regs, then we can get downforce at all speeds, simply by fitting a rocket engine to the roof, facing downwards, and firing when we go round a bend......... ;-)
Ferget rocket downforce. If there's no rules then a vertical symmetrical aerofoil wing with active control of AoA to generate whatever lateral force you needDOWNFORCE

If you stick it up front then the induced drag can be harnessed to create extra downforce at the rear

I've just read the specification sheet for the Impreza WRC they used for the record attempt. Bloody hell that's a serious piece of kit, even with 300hp. Anyone who thinks that is not a proper racecar doesn't know what they're talking about.
All kudos to Mark Higgins wrestling a 600hp version of that around the Mountain Course.
Did I really read someone saying that they could go faster around the TT circuit on a simulation? Half term innit.
