Faster than an M5 for £25k

[LayZ]

Some TT RS running big power, but then again these aren't that cheap to buy. Not much under £25k.

Pretty hard challenge really without going full turbo nutter tuner car.

This has 730hp apparently for £20k - should do it:

But agree with J4CKO, remapped Bentley Continental got to be easy 700-750 which should do it.

V10 RS6 and a remap?

As nice as the V10 sounds I don't think it would be enough against an F10 M5. You'll want something with forced induction I think, bigger gains.

Could you supercharge a C63 reliably?

The 2 turbos on the V10 rs6 help.

Googling these suggestions is a great waste of an afternoon but sadly M5 still king of the hill so far.

The new M5 is on par with these 2 (Panamera and E63 S), and here is a mapped RS6 getting destroyed by them both on an Autocar drag race from last week.

I really don't think there would be anything quicker for £25K unless you go down something prepped for the drag strip with a massive turbo.

I recall the PH Sunday Service at Santa Pod

There was an Audi - IIRC an S3 that had been tuned to 440bhp but that combined with AWD and DSG meant it was one of / the fastest thing there - it beat many Ferraris etc

Obviously it's ingear / top speed would be less impressive but the way it consistently launched every time was impressive.

How about a W211 E55 AMG with a smaller pulley and remap. No more than 15k in for a good one.

I was thinking exactly the same thing, even a re-map on the 5.5 supercharged engine sees 540bhp so pulleys as well and you'd be over that of the M5.

Admittedly a lot more 'old school' than the F10 but if you're talking sheer BHP that would do it.

They need a pulley to get that much power. Exhaust manifolds aren't that good either.

A friend of mine had a client with an E55 estate, that had pulleys, re-map and I'm assuming other work but was about 700bhp which is pretty mega.

That will have had a fair few extra bits. Mine with a smaller pulley and Eurocharged ECU and TCU remap was only 522bhp.

It's probably going to be a challenge to beat an F10 M5 in a straight line for 25k. Shame because I'm not a huge fan of the F10 5-Series.

W211 E55/E63 AMG more to my taste but probably not as quick.

996 Turbo or are they way over 25k now? Less power but lighter and more traction off the line.

Can you still pick up a Cerbera for 25k. I remember them blitzing everything else by a significant margin in a straight line in a Top Gear special back in the day.

Would anything with the 5 litre supercharged Jaguar V8 do it? e.g. XFR/XJR/XKR?

You can pick the odd one or two up for just under £20k too.

A Cerbera is undoubtedly quick, but the one used in the test was very

[speedtwelve]

The Cerbera that definitely did not have a TVR Tuscan race engine fitted for the Clarkson vid?

[cerb4.5lee]

I was just happy that Cerbera regardless of what engine it had in it...managed to get to the finish line without breaking down!!

That was the biggest shock for me!

We’re those race engines 4ltrs? If so a search for the numberplate and V5 would verify it one way or another

[speedtwelve]

Looks like the Clarkson vid Cerbera was a 'healthy' AJP 4.2. The long-term test TG Cerb had a Tuscan Challenge 4.5 fitted. I remember being on the Birmingham motor show TVR stand back in the day where they had the Cerbera drag race on continuous loop while Peter Wheeler stood back and watched the orders get signed. I wish I'd bought a Cerb rather than my Chim 4.0.

Faster than an M5 for £25k? I'd either go with twin-turbo'd Monaro VXR or supercharged VXR8 with tweaks.

I feel very suspicious this would fail the costing the same over the next 12 months or 10,000 miles part of the challenge.

Also, no direct inside knowledge on that Cerbera drag run but last time this came up on the forum I remember someone saying it was standard except a decat. My 4.2 AJP was fast.. really fast over 70mph. Under 70mph it was so hard not to let the wheels spin and then even harder to stop them spinning and get back on the throttle

The 4.5 is 377bhp/tonne that’s mighty by anyone’s standards (and it’s cheaper to buy used than a BMW M4..... go figure why people buy the M4 instead of a savage muscle sports car )

[otolith]

Probably depends on the length of the drag race, but these will be pretty quick off the line;

A 300+bhp sub-800kg supercharged Honda S1 perhaps?

[jakesmith]

I was on the M6 years ago in my 997 C4S (355BHP). Was going through a 50 zone with what I thought was a 520d on my tail. As soon as I passed the last camera I was in 3rd gear ready to floor it & nailed the throttle & redlined it & same in 4th, the BMW flew by me, I was honestly astonished at how much faster it was than me. Now the 997 isn't that quick by today's turbo standards I know but it really left an impression on me as a devastatingly fast car.

How about a Jag XKR 5.0 Supercharged with pulley & map, they're 550BHP aren't they, can't be slow.

Should have been in second !



There's another 911 driver out there with a similar tale... I came upon one when I was heading for Super Car Sunday at Gaydon, in my Father's C Type Replica - built for racing with a 400+bhp V8 installed, as we came to an island, I saw the 911 driver looking in his mirrors, I saw the back end squat as he exited and then I flew past him like he was standing still.

So perhaps an answer to the OP is various modified "kitcars" however none would do the same job of ferrying 4 plus luggage in comfort.

[SturdyHSV]

Supercharged Monaro / VXR8 is at least a cheap / reliable 650bhp or so, so worth considering and comfortably under 25k.

Cheap C6 Corvette would be the same engine / gearbox / general cheap maintenance but about 300kg lighter so worth a look, stick a supercharger on it and go rather quickly indeed, supercharger kits readily available from the US

C6s are significantly more than Monaros and such though, so the money saved on the car could buy you more power...

[Felix79]

Rather than an M5, I would prefer to go for the Alpina B10 instead.

Reliability/dependability would be a couple of good reasons. I love the Cerbera 4.5 for sure but I also wouldn't say no to the M4 either. The performance of the M4 is astonishing for me given how much it weighs.
