Default Caterham 7 RST-V8 with 500+ HP Supercharged 2.4L V8






Quote:
As if 400 HP weren’t enough for the cart-like Seven roadster, Caterham has introduced an even more extreme version of the car developed in conjunction with niche engineering house, “RS Performance”. Dubbed as the Seven RST-V8, the ultimate Caterham packs a supercharged 2.4-liter 40-valveV8 engine that delivers more than 500 bhp at 10,000 rpm and 300 lbs-ft or torque at 8,500 rpm.

As if that wasn’t enough, weight reduction runs throughout the car, from the carbon fibre interior finished with Kevlar seats down to the hosing used on the cooling systems. According to Caterham, the RST-V8 weighs in a mere 520 kg or 1,168 lbs.

In terms of acceleration figures, the Brits claim that the ultimate Seven goes from nought to 60 mph (96 km/h) in less than 3.0 sec. In case you’re interested, prices for the RST-V8 start in the UK at £115,000 or $226,300 / 152,700.

Considering the power to weight, how usable is the power? Would you be spinning the tires in every gear, coming out of every corner? I wonder if the traction gained with some sort of AWD system would be worth the weight penalty?

I admit I am not well versed in Caterham,but here it goes

Why did they go with a 2.4L V8 as opposed to 3 or 4 liter.I imagine size but an odd choice.

That's what F1 is limited to, there must be a good reason

Im sure it has to do with weight, size, and of course rotational mass inside the engine to achieve that type of rev limit.

such a car would deserve to only be driven on the track in prime conditions, shod with R-comps or, better yet, real race slicks.

Well, the power is likely to be spread over a large rev band (10k) and the torque isn't as crazy as the hp, so it shouldn't be too insane, still insane nonetheless but a little less so

The engine is made by Moto Power and based on two motorcycle I4's.

the engine was originally based on a Hayabusa heads. 1200 x 2 = 2.4L so it basically two motorcycle motors in a V.

I think they were working on a 2.6L version.

And really, with around a 200lb pilot, this and the Hayabusa share a very similar lbs/hp figure. (About 2.73 vs. 2.75lbs/hp).

The Caparo has a similar power/weight ratio - I think your biggest issue with this Caterham would be the same issue the T1 has: traction at lower speeds (exiting corners, etc.). Aero can only help when you're going at full speeds, but I don't see that much in terms of aerodynamic aids on the Caterham...

I'd still take a Caparo over this, there's just something intoxicating about a car that is just as likely to burn you alive as beat the Top Gear track record by 6 seconds.

That's the other thing I was wondering about, the aero on the Caterham. I imagine on a big track, drag would be somewhat limiting. Just the drag of your head has to be significant (Clarkson in the Atom......)!

While I do think Caterhams look like crap, there's no denying the bad-assedry of this vehicle. I would do really stupid things in order to own this car...

Good info thanks.
In the Ariel Atom,It looks like the plugs go through heads like in the old Hemis.Also the engine is bigger than I thought it would be,when you said it was 2 motorcycle engines in a V.

Very cool, but that's A LOT of cash for a ltd purpose vehicle. I guess I just need to make more money.
