Can any body work out what sort of BHP, and final drive would be needed to reach this speed, There is a guy on the RRS forum claiming his RRS will do 160 MPH. Just interested to know if he has a pub GPS fitted to his car !!

Really depends if its a HSE or HST, HST's are rare and are V8 not V6 like 95% of RRS, driven both a lot and the HST,s are a totally different beast.

I don't know if either will get to 160 as the wind resistance above 130 would be huge, don't know what the official stats are tho, might be surprised.

mates cayenne struggled past 145, even with 500 bhp and that's much slipperier than a brick

xr2mk2turbo

Just had a quick look at some reviews for them and 140 is max for a V8 HST, I guess you would need a lot more grunt to get another 20 mph from something as aerodynamic as a lorry

RigPig

I have got the TDV8 HST, but this guy has the 5L SC model

Boss has a RRS 5.0L V8 Supercharged and I wouldn't be surprised if that could do 160: downhill : off a cliff.

Parkers reckon 155..

lol me assuming it was the diesel as you don't see many SC ones up here, different ball game then, I have no idea

RigPig

That's for the new model, this guy is on about the older version

I read the thread you're on about, he's full of shit, it won't do 160 and tbh I wouldn't want one to get anywhere near that!

are the tyres rated for that speed?

Does he not mean 106 lol.

DavebST170

that range rover that jamsport built didnt even hit that speed and didnt that have 600 or 700hp iirc

HaggisTurbo

Wouldn't be me driving at that speed in one of them to be honest, would be terrified of the thing flipping over!

Fullflush

I'd be sceptical of anything Jamsport claim

Rod-Tarry

Dont need to be the rating is continuious running for several hours. My tyres are rated at 186mph but have exceeded that many many times.

Rod-Tarry

49% more Power required. The gearing would need to be lengthened by 10% or so which would require a lot more Power or a lot longer runway.
I doubt the standard car would get near its max in 1.5 miles so where is this guy doing this . If i had the time I would go on line & destroy him with the maths.

they claim 172 as the top speed for the cayenne, on a runway maybe, but never on public roads could you do that, even autobhans, that's a really slippery shape too, the new rr might be more aerodynamic than the previous ones, but that's like saying a car that does 9 mpg is better than one that does 8

but what gives it away seems to be that the speedo on the range only goes upto 160 mph

xr2mk2turbo

Would take a lot of work then, and you wouldn't want a wobble letting off the throttle and braking, I take it 1.5 miles is the longest private place to do it? Do you have to allow braking time within that too? I bet even the supercharged ones don't accelerate very well at all say after 120

Well if a fiesta can manage 150mph+ with mild mods I think a range rover can manage 160mph happy.

MikeyRobbo

It not as simple as just throw shitloads of money for more power and that's it. Wind resistance is a massive factor at those speeds and if i remember right, a fiesta is a little tiny bit more aerodynamic than a range rover. Then not to mention gear ratio's an shit.

Any chance he did this indoors on a dyno?

Where is this 150mph Fiesta anyway?

Rod-Tarry

Heres one doing 178mph is that more than 150mph .

Rod-Tarry

Not into Topspeed running I guess .
Its all to do with aero nothing else matters.

A Porsche with 640bhp can exceed 200mph & stop at Brunters a Cossie needs around 730bhp to do that. A Saff needs less than an Escort as Martin found out. How much a double decker bus would need, well lets say rather a lot.
No one is saying this BM cant reach 160mph just that it will take 49% more Power than standard & another 10% or so to pull the longer gearing it will require. So I guess a 60% increase would see it reach 160mph in the same distance as the Standard car. In the 1.5miles of a runway it would not get near its max speed. For instance a Ferrari 360 just nips into the 170's There.

MikeyRobbo

Fuck me Still not a Fiesta with 'Mild Mods' though

Rod-Tarry

Thats not the record thats held by Paul Johnston @ 179mph.

my old mk1 cayenne turbo would happily tell you it was doing 165mph, it was close but doubt it actually cleared 160mph.
it would fling up to 145mph (when abroad) then still gain well but you need room to get really quick while watching the petrol guage drop quickly...
it was markedly quicker than a 07' (iirc) supercharged range above 130mph
it was on air and also lowered 40mm so maybe than helps (short links and reset the ecu)

you pal from the other thread is mistaken imho

Please find the time Rod !!

my mate is into his fast cars and his turbo was properly rapid, he was even looking at getting one of them gemballa kits to get it up to 650 bhp but then put his sensible head on and figured that it was quick enough as it was

but he never took it above an indicated 150, i've got a video of it somewhere i might post up if i can find it

he would get between 9-12 mpg on average and he ran it for about 5 years like that

but he was shocked at how much slower the rrs sc was when he was looking to buy a new motor last year, he compared it to a "diesel"

yes rod, please find the time

I got to drive a new L494 5.0SC on the test track at work (I work for JLR) and can confirm not only did it do 160 it went off the end of the 160mph speedo, as for an old L320 RRS doing 160mph...... no chance not with a standard AJ133 SC anyways
