Now let's solve this

UF1

Based on/looks like - Original mini.
Power, weight, capcity - 55hp, 600kg, 1000cm3
1961 Austin Mini Cooper - 55hp, 584kg, 1000cm3

XFG

Based on/looks like - Citroen Saxo
Power, weight, capacity - 115hp, 940, 1400cm3
Actually, I can't find a Saxo with 115hp, regardless of engine size
2003 Fiat Punto Fire 1.4 - 93hp, 960kg, 14000cm3.
NOTE - If anyone can find something more like it, I'll include it.

FXO

Based on/looks like - I've always thought Calibra but it looks more like a Astra, especially the lights. Well, a Calibra but with the SilEighty style sellotape the bodywork of something else on looks.
P,W,C - 234hp, 1140kg, 2000cm3 with turbo
1992 Vauxhall Calibra Turbo - 203hp, 1405, 2000cm3 with turbo
1990 Vauxhall Calibra 2.0i - 117hp, 1195kg, 2000cm3 without turbo.
NOTE - Looks like the engine from the 1992 Turbo has been put in to the 1900 2.0i

But remember kids, they aren't supposed to be exact copies of road cars, but the power and weight stats are roughly comparable to existing cars. Some road cars might want a little bit more lard though.

Quote from harjun :

yes, but a VW Golf 1.6 is 60hp

Is that a new golf? My sister's 1976 beetle has 75...

I still think the rb4 is underpowered. a 2 L turbocharged engine only delivering 243hp?
I'd be ashamed if that were my car...
a miata 1.6 with greddy kit easily puts out 200hp at least...
the rb4 with around 275hp would be a bit more realistic imo...

As I just posted, a Vauxhall Calibra has "only" 203hp!

It's already been discussed that the RB4 needs a wider-powerband. IMO this will help it much more than more power.

Quote from ussbeethoven :

...Punto GT: no turbo...

You should search for more accurate datas then...

'94 Punto GT engine's spec:

-1372 cm3, 4 inline
-8 valves, SOHC (belt)
-IHI turbo. (0.8 bar)
-~136 hp @ 5750 rpm / 21.2 mkg @ 3000 rpm (which is certainly not N/A revs).

then again I don't reckon a calibra is a true sportscar, wich the rb4 is obviously meant to be...

Theres loads of wrong online datas for cars/bikes/etc...

Definitely should happen when the turbo modeling is updated.

The XFG is definitely over-powered. It should have about 97HP instead. Because, my 1996 Saturn has a 1.9L engine that only makes 124HP. That's about 65HP/L. The current XFG has 88HP/L, which is similar to that of an Aston Martin V8 Vantage. Let's say the XFG has a more well-engineered engine then my Saturn (which is very likely), and it has 75HP/L. That would mean that it should have 97HP. 115HP out of a 1.3L is too much.

have a look at the first 2 cars.
i know they used to be race cars, on the other side theyre from 1971.

Well, assuming that the XFG is bone stock...

OSCO: http://www.rallycars.com/Cars/ ... /Street_Celica_ST205.html

This is the car RB4 is inspired i think, and it resembles it's specs...
So to me Rb4 it's fine with his hp.

and its still supposed to be 10 years older.
if i search hard enough im sure i can find at least 2 stock road cars with 1.3 l which have more than 115 hp.

240bhp is more than enough for a fairly light road car, the new TT only produces 200bhp from a 2.0 litre turbo. The cars in LFS are meant to be road cars, not highly modified or impractical for daily use.

Quote from Jakg :

160 HP out of a 1,300 CC Engine?!

1999-2007 Suzuki Hayabusa motorcycle, 1.3 liter, 175hp at the crank. 2008 Suzuki Hayabusa, 1.34 liter, 190hp at the crank.

Regarding the power increase in the cars overall, there's no reason that LFS can't include cars of the past and current cars, which would be my preference. Then again, will H shifters become a rarity 10 years from now? BorgWarner makes a semi-automatic manual dual clutch transmission, and Volkswagen is putting a lot of these into their low end cars as well as Audi TT's.

Formula 1 cars are mostly using seamless shifters now, with more computerization planned by 2009 to reduce drivetrain breakage and the associated costs.

Motorcycle Engines is a fair comparison how...?!

Quote from Jakg :

They're used in a lot of small single seater cars, and LFS includes a few of these, the most recent example is the Formula BMW, which uses BMW's somewhat underpowerd 140hp 1.2 liter engine. The motorcycle clutch and tranny aren't used, instead a Sachs single plate dry racing clutch and Hewland sequential shifter are used.

Regarding power in general, there's been a power war going on in the USA, and the rest of the world has now joined in: 2008 Chysler 300C SRT8 / Dodge Charger SRT8 - 425hp. 2009 Nissan R35 - 473hp. 2006 and current Porsche 911 Turbo, 480hp. Mustang GT 500 - 500hp. 2006 and current Corvette Z06, 505hp. 2008 Porsche 911 GT2 - 530hp. 2005-2006 Ford GT - 550hp. 2008 Viper - 600hp. 2009 Corvette ZR1, 620hp.

Then the exotics: Porsche Carerra GT (2006 was last year mad) - 612hp, 3043 lbs. Koenigsegg CCX - 806hp, 2600lbs.

Right. Show me a mass-produced road car using a Hayabusa engine again?

Depends on what you mean by mass produced. Do a web search for "Hayabusa race car", and you'll find hits like Super 7, a LX4 like car with a Hayabusa engine in it. The Radical SR8 uses the heads from two Hayabusa engines to create a 360hp 2.6 liter V8.

I mean that i don't remember going into a garage and seeing something vaguelly resembling an XFG with a 190 HP Hayabusa engine in it, which is what most of this thread is about.

Honda's S2000 was orignally getting 240hp from a 2.0 liter. The current 2008 version use a slightly slower revving 2.2 liter that outputs 237hp. I think the redline was 9000rpm for the 2.0 liter engine, and 8000 rpm for the 2.2 liter engine. Note that the 505hp Corvette Z06 7 liter V8 redlines at 7000 rpm, so it's not just small engines that can rev relatively fast these days.

Not exactly mass produced but you can have a 'busa lump popped into a Saxo, Zcars do a good job of it by the looks of things.

my sisters VW Polo i mean does 65hp

Also...my brother S14 Silvia 2L at 1.2 Bar with the Power FC ECU, does 300BHP...

Still has the 2.0 litre in all other countries (UK anyway)
