An Impreza did a 113mph average at the TT what to do better?

[Herman Toothrot]

Over in biker banter the its been posted that the American Impreza posted a 113mph average, up from the old Rover 827's 102mph average 20 years ago.

What would you choose as a contender to go fastest know knowing thats how the Impreza did?

My money would be on something like a 997 Turbo or GTR with suitable modifications, so you get the higher top speeds like the bike but retain the 4 wheel drive like the Impreza.

a hill climb car with a big fuel tank and appropriate gearing.

Elaborate, a classic mini could be a hill climb car as could anything else.

What do the bikes average round the TT ?

131mph I believe was mentioned today.

the trouble with most rally type cars is that they don't have the top speed for the course, which is 180mph plus for long sections on the bikes... this is why a single seater would be best.

You don't subscribe to what most of the bikers say - that its to bumpy for single seater and cars with ground effect aerodynamics?

I admit I'd be suprised if a single seat race car would have that much trouble as the side cars don't don't have many issues. Infact they go as fast as the Impreza did.

We're talking about thing that will beat an Imprezza, not a bike, aren't we?

Glad it isn't just me who thought that

Yes definately, talking best car for the job as now we have another reference point other than a 827 Rover. The Impreza bettered it by an average of 11mph taking it up to the 113mph, about the same as the 600cc side cars.. its still 18mph average slower than the fastest bikes. Hell of a difference so not really interested in if a bike could be beaten, just whats the best car for the job of going round the track as fast as possible.

So the 911 turbo somehow accelerates faster than a superbike? I really don't think so.

Also it corners at the same speed despite being unable to use the same amount of road due to the width. It could probably get a 120mph lap but I don't think it would be any higher.

I've just been trawling looking for data and its hard to find figures but I did find a thread discussing a video of 1/2 mile drag races between an R1, a Carrera GT and a Veyron and the comments were along the lines of "the cars both make the bike look like its stood still". I found a few 1/4 mile times and it appears something like an R1 is equal to a Carrera GT over the 1/4 both doing 11sec. So I guess the higher bhp of the cars takes over towards the top end. A 997tt would be 1 sec behind over the 1/4 but again would it reel in a bike up at 150mph.

Anyway I'm not that intereste in faster than a bike or not, just best car for the job.

Just be glad that the TT still exists when so many other road races have gone.....

Absolutely!

However the very fact the TT goes on for bikes will make people think 'I'd love to see a car go round the course' and if you are going to see a car go round I'd like to see the fastest car possible.

I have always thought a rally type car would be best and its obvious a WRC or old group B car would go round a lot faster than a road going Impreza. However as the bike guys point out, not enough top end. Then however you have experienced circuit drivers and hill climbers saying full on single seaters would take the abuse of the course, so maybe you don't need a rally type car after all. This then makes me think they maybe faster... But would someone feel safter and push harder in a full body caged car than in an exposed single seater?

Its obviously an interesting thing to think about as demonstrated by all the replies.

Have we worked out what the best car go round the course the fastest is yet?

That was the point of this thread.

I'm leaning towards the single seater hill climb cars if going 'racing car' but I do have reservations about how they'd cope over the jumps without having to really back off.

For a road car to hurl at the course rally car style but not have the top end the GTR has to be a contender.

A happy medium a de-restricted WRC car :-) which I think would be the best to watch go round.

115.356mph for that lap ...superb

Wish I was there watching as well, think next year may have to be a TT trip rather than GFOS if it ends up being a running theme bikes with a bit of car thrown in as well

In respect to them though that was the question that opened the thread ("what could beat the Scooby"). With only a WRX STI being used, it was a fairly easy question to answer as well (the answer's "pretty much anything that's known as a performance car"). Nevertheless, there's a certain appeal to seeing a driver of the calibre of Mark Higgins thrashing a bog standard road car on closed roads.

Thats taking the title at face, the post was more what would you choose to go fastest. I thought when I made the post that it would turn out to be a WRC style car v's am F1 type car thread. Instead lots of people seemed to want it to be a more car v's bike thread which wasn't the intention - biker banter already had that thread.
