No the fact is the Suburu should have done a 120mph but mechanical failure harmed the remaining 8 miles of the track.
So assuming it should have done 120mph. What's the time difference between a 120 & 127mph lap? Then over 38miles could said faster car make up that time?
Lot's of assumptions in all your theory's, what amount of speed did he lose due to brake fade? How bad was the brake fade, previously you stated he relied on engine braking, if that was the case, around the tt course I suggest he would have curtailed the attempt post haste, so brake fade yes, huge fade? I don't think so, and in that case its supremely difficult to assess how fast he could have gone.Again how quick is the new car? Again no one knows, just wait and see.

Pre brake fade he was on for a 120mph lap. Evo article is linked earlier.

All else being equal it has between 50-100% more power and a much higher speed plus much more aero. Are you saying it will not be quicker?

So far 3 attempts
Tony Pond 827i 100moh average
1st Suburu run 113mph (learning he circuit)
2nd Suburu run 117mph with 20% of the course with ruined brakes.
I'd love to know how much faster it would have been with brakes which lasted the entire lap? Would that alone have done a 120mph+ lap.
With a rolling start so it was doing 130mph across the startline & was still slower than the Electric bikes that have a standing start & have to back off around the lap so as not to run out of juice. Tony Pond 827i 100moh average
1st Suburu run 113mph (learning he circuit)
2nd Suburu run 117mph with 20% of the course with ruined brakes.

A good marker are the 250cc that have a flying lap record of 118mph.
I'll go on record now & say if it hits 123mph lap I'll donate £50.00 to help for heros.

It's only as fast as the bloke driving it and ultimately talent and physics will determine how fast it goes. You cannot just double the power and automatically go twice as fast. I remember back in 2000 David Jeffries broke the record with a 125mph lap on a V&M R1. Last year the record went again with 132mph (I think) so that's 7mph in 15 years with all the advancements with tyre technology, power and suspension. Bikes and riders come back year after year, forever improving and practicing. This by comparison is a PR stunt by Subaru and whilst he may go a bit faster, I don't think the extra power will make as big a difference as most people think. Are you saying it will not be quicker?
Tony Pond did 100mph with a standard Rover 827 with 180 ish HP.

But hats 7mph over 15years with each time the machines at the pinnacle. That Suburu while good is far far from the pinnacle of car performance. Tony Pond did 100mph with a standard Rover 827 with 160 ish HP.

Its not just barely faster though is it, your estimate of a 127mph lap is a huge leap.

On Saturday one of our riders should have broken 130mph if he'd strung all of his good splits in practice together so far he's at 127mph & it's not for lack of commitment.
The 130mph barrier was broken in 2007, 10 years later we're at 132mph.
Hutchy had a blown exhaust which is a killer for an N/A engine & still managed a 132mph lap but you really don't realise how hard it is to gain that extra 1mph per lap if your bikes to stiff any speed advantage you had is lost through the bumpy sections of the track, you go to the NW200 with a stiff bike like the R1M & you can be up there, you get to the TT & your shedding time like it's going out of fashion.
Even with the big brakes he had last time he ran out towards the end which shows how much more he was using the brakes than the bikes were.
However it turns out it'll be a good watch after all the fun & games are over.

Bruce Anstey managed 132.298mph on the sixth and final lap of the 2014 Superbike race and Michael Dunlop holds the race record of 1h 29m 29.98s or 128.747mph over six laps including stopping for fuel and tyres.
Maybe the car should do six consecutive fast laps including stopping for fuel, tyres, new brakes, new suspension, new transmission, new engine etc and we can see how fast it really is?

I've knocked a little table up showing average speeds and lap times, plus the improvement needed (in time) to get to each average mph increment.
(I was bored, ok...)
Hopefully I've got this right; I've used 37.73 miles as the lap distance as I believe that's what the TT timekeepers use.
Ok so let's say his actual attempt without his brakes fading and needing to use engine braking for 8 miles meant he did what he was on for at the 80% mark a 120mph+ time. (I was bored, ok...)

Big assumption sure but let's use that as the line in he sand purely for arguements sake.
Now if 120mph was the level then a car with 50-100% more power with less weight and massively more step much better suspension setup and one years tyre improvements - would people think over 38miles MH might be able to find 9 seconds? Personally I think they are thinking if everything goes perfectly they have the tool to deliver a 130mph time but may come away with "only" doing a 125mph.
I suspect this new mega subaru will post a faster time than last year, assuming there is no mechanical failure or driver issues. But I don't think it will come close to worrying the top bikes at all, purely due to its width. I would guesstimate 125mph absolute max average if he really strings it together perfectly. Although in reality and being more realistic / pessimistic, I wouldn't be surprised if it was lower than this, at say 122mph ish.
I hope all goes well and everyone finishes safely, in cars and on bikes. Best of luck all, you crazy heroes!
