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

[rallycross]

This topic came up last year and a few people suggested evo/'impreza/gt3.

Anyone know What spec was the impreza was? Track prepared Spec C?

US-spec Impreza with a remap for high-octane fuel + some safety equipment and a loud exhaust.

Probably closer to standard spec than Pond's car was.

we used to have f1 cars around the old spa and at the old nurburgring, around rouen, GT cars around sicily at the targa florio... it's no issue.

I wouldn't be surprised if even a 1970s single seater could beat the current bikes at the IoM.

Ultima GTR with slicks and a seriously tuned engine, probably supercharged for drivability, should get a fair lick on!

Don't think an F1 car would ket heat in it's tyres.

A Pikes Peak car would be a bit more like it.

Yes, but not ground effect cars with zero ground clearance, and the Florio GT's are not exactly extremely low race cars. The other thing is that even a moderately bumpy Spa or Nordschleife isn't a bumpy public road with drain covers, dips, hollows and a hump back bridge. Have you actually watched the coverage on the TV, the bikes are all over the place.

Pick from any high end 180+ performance car tbh.

But I would suspect course knowledge counts for a fair bit too. To use an analogy. Everyone knows the locals at the 'Ring in their ratty stripped out Mk3 Golf Gtis who lap faster than Brits in GT3RS'

Ariel Atom V8 or possibly a Radical SR8LM

Ariel Arom V8

What with a top speed of what 140 ish? Dream on. Wouldn't even get close.

The normally aspirated Honda car with half the power will do 140, so I should think a V8 would manage a good 170ish.

I'd probably pick a Radical if it has to be road legal.

The Atom 300 has a top speed of 140ish, the V8 would be around 160ish? That is plenty enough to beat an Impreza averaging 113mph.

Let's say it does do 160 which with those aerodynamics is doubtful, it would still not come close. The bikes are doing 180 plus for very long periods.

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

If you want to beat a bike, how about a Caparo T1?

You think a car with around 500 bhp won't be able to do 160mph? I would say 180mph+ is perfectly feasible with the right gearing. (Ariel say up to 200mph for the race version, although that might be a tad optimistic)

0-100mph in under 5.5seconds is not to be sniffed at either. The power to weight is better than the current GP2 racing cars.

The Caparo won't even get out of pit lane, every test shows it broken down or in flames :-) Guys, you will need proper road car road clearance, yes, Nordsleife, Targa etc are/were proper roads but they are not repaired pot holed roads with big bumps and all the road furniture. From experience the TT circuit is proper bumpy in places and that was on a road bike (996 sps duke and latterly a 2008 blade) with a steering damper and not at suicidal speeds

Much as I hate to say it, a GT-R with the top speed limiter removed?

Eh?

The V8 has just over 500 bhp, and a power / weight ratio of circa 900 bhp/tonne.

It'll be knocking on the door of 200mph, I'd imagine.

the trouble is that power to weight ratios don't matter when deciding top speed.

and once above 150 or so, a bit more power will be not a lot more speed.

I understand that, but Ariel themselves reckon on near 200mph, plus they've spent quite a bit of time getting the aero on the V8 right,

Wouldn't surprise me to be honest.
