Modified Jap car race SL500??

abaden, twin turbo V12 leh.Originally posted by LazerLordz:Yes.SL500 takes 6.2 secs to hit 100kph.Something easily beaten by the Maserati Spyder my family had in the 90s..
But the SL600 and the SL55 is a different breed..4.7secs stock.

haha, i think unless ur fren PI the car, he wun get a jdm spec bugeye sti lor. those gotten from MI all 265 bhp one.Originally posted by jonathan_n80:FYI its a JDM model bugeye. 280Bhp when stock.
base hp is pointless. fact is he still lost to the F355 on acceleration. that simply shows that his mod job still pretty basic. a rex with at least 350 bhp and above should have no probs takin on a F355 much less to say a sl500. -
i would onli jus like to highlight to u that a JDM is 280Bhp. in case u might think a JDM is 265Bhp. bugeye with a wiper at rear windscreen.Originally posted by tailslide:haha, i think unless ur fren PI the car, he wun get a jdm spec bugeye sti lor. those gotten from MI all 265 bhp one.

Actually it would not quite brush aside a F355 or even a SL500 that easily at that power level if we are talking about a straight line sprint. What some people fail to realize is that more often than not, a Subaru WRX or similar four wheel drive sedans will not get a perfect launch and furthermore they are not competitive with other established sports coupes when it comes to straight line sprints (not just 0-100 km/h, which is more a measure of mechanical traction at launch than a true measure of a vehicle's acceleration). This is because of several variables -Originally posted by tailslide:haha, i think unless ur fren PI the car, he wun get a jdm spec bugeye sti lor. those gotten from MI all 265 bhp one.

1. There is a large amount of mechanical traction from the all wheel drive system in which is equipped in the STi. When in standard 50/50 split it is very difficult to break traction on dry tarmac, especailly that of in Singapore as they are generally very smooth surfaces. Large 225mm width tires equipped on the STi, which help provide higher cornering limits, further contribute to this launching 'problem', This is why often STis or GT4 Celicas of stock form or light-tune are clocked quicker sprint times on light gravel surfaces or in slightly damp conditions where there is a slicker surface in which the tires can spin and gain static momentum, albeit for a very short period, before direct acceleration. A relatively powerful two wheel drive vehicle, such as the SL500, will not have as much a problem of 'bogging down' on dry tarmac as there is less mechanical grip as 302 bhp is diverted directly to the rear two wheels.
2. Driveline drag - This is inherent in an AWD system as is present in the STi in this case. It is not present in a variable torque split system such as is present in the Attessa-4 of the Skyline GT-R, which is in standard non-slip form sending power directly to the rear wheels only, albeit it still suffers from the weight compromises of a four wheel drive system. This driveline drag is what blunts acceleration in theses road-going rally car specials like the STi and Evo 8/9 at higher speeds (*ie. above 160 km/h) and is a contributing factor to why a regular Subaru WRX 'bug eye' GD8 is marginally slower from 0-160 km/h than a Renault Clio Sport.
3. Aerodynamics - The WRX STi is inherently a sedan that has been made into a rally racecar (WRC) or in road-going form a high-performance sports sedan. Because of the fact that it is 'shaped' for rallying (ie. extended wheel arches to provide a wider track, front splitter/ rear spoiler to provide downforce and negate any negative lift) it is not have a low drag coefficent. This is accentuated by the fact that it is a four dour vehicle, not a two door roadster/ sportscar as the SL500 and moreso the F355 are. This further contributes to its limited straight-line performance, stock or lightly modified, at higher speeds, and this is where the SL500 will edge forward and the F355 blow away the STi. These two performance vehicles are known to have some of the lowest drag coefficients (0.29 for the SL500, 0.32 for the F355 and 0.34 for the Sti, which has a much larger frontal area and hence more aerodynamic drag still) (the F355 with an underbody designed to generate downforce at high speed and as such does without exterior parts that would add drag performing the same function) and small frontal area which contribute to a strong acceleration at higher speeds, in this case even above 100 km/h the STi will not have any advantage in acceleration in any circumstances.
Furthermore, the SL500 is generally very underestimated. German horses are generally known to be 'stronger' than Japanese ones and as such the 302 bhp claimed by Daimler Chrsyler is most likely a conservative figure, especially considering the high torque output of the engine. The F355, on the other hand, has got a 375 bhp V8, which would definetly see off all but the most highly tuned WRX STis in a straight line sprint. -
khl, u have raised some valid points.
but considering the advantage of the added traction and low-mid end capabilities of a turbocharged awd vehicle like the rex, it should have no probs dispatching a sl500 in stock form or f355 in a well tuned state. not forgetting, the sl500 and f355 are both not relatively light cars by any measure. in terms of power to weight, essential to measuring acceleration, a rex is comparatively more likened to beat a heavier 2wd vehicle for pick up while the heavier vehicle struggles to overcome its initial inertia. -
if i have not mistaken e 355 and the Scooby are of almost e same weight.. or perhaps e scooby is heavier than the 355 by some kilos..

Why do u always compare a tuned car with a stock car? take a stock rex...vs a stock SL500 or F355 la...Originally posted by tailslide:khl, u have raised some valid points.

y u all compare 355, SL500 and rex ah?
its like comparing sausages, screw drivers and roses, completely different class.

stock rex n stock 355 are of different class.. but e scooby STi definitely can take on e SL500 both stockOriginally posted by zheshi:Why do u always compare a tuned car with a stock car? take a stock rex...vs a stock SL500 or F355 la... -
But their car own easily buy them a wrx or evo ...Originally posted by jonathan_n80:Some time I have someone driving modified(at least exterior) conti, like Audi, Volkwagon, Mercedes, Â…Â….wanted to race with my 1.3L baby.
What do you think is in their brain, do they really think that by changing into a Apple-stuffing pipe x 4, high-eyes blocking rims, replica racing sticker……etc can make that Conti “saloon” into a sport car????!!!! -
hm. wrx need skill to launch. not as easy. the only fast wrx(noy STI) are those gc rex. which come 280bhp stock. light somemore. sl500 got launch control not? i dun own one so i dunno. but so ex tink got liao lar...and auto...not really diff to launch i guess.

but then the added weight does not justify the extra power...I'd rather take the SL55...just nice...and definitely handles betterOriginally posted by TwinTurbo_Supra:abaden, twin turbo V12 leh. -
I agree with that statement...conti cars measure BHP at the wheels while japs measure BHP at the flywheel....cos by the time it reaches the tyres there will DEFINITELY be power loss...due 2 drivetrain etc...Originally posted by Ali_Khl:Furthermore, the SL500 is generally very underestimated.

yeap, u are rite. by perhaps a few kilos. got too caught up with the comparison with sl500 and f355 and rex. i meant to say that the sl500 is much heavier. by almost half a ton if i remember correctly.Originally posted by jonathan_n80:if i have not mistaken e 355 and the Scooby are of almost e same weight.. or perhaps e scooby is heavier than the 355 by some kilos.. -
y i cannot compare? read the topic first before u question y i compare a modified rex with a sl500.Originally posted by zheshi:Why do u always compare a tuned car with a stock car? take a stock rex...vs a stock SL500 or F355 la...

SL65?Originally posted by AE86tofu:but then the added weight does not justify the extra power...I'd rather take the SL55...just nice...and definitely handles better -
SL65 also not bad.. quite a nice handphone.. anyone use it before??Originally posted by TwinTurbo_Supra:SL65? -
heavier than the SL55....no thanks....sl55 has the right balance of powerOriginally posted by TwinTurbo_Supra:SL65? -
pls Read the first post of this tread before u question me back... if u want to be so caluative ....Originally posted by tailslide:y i cannot compare? read the topic first before u question y i compare a modified rex with a sl500.
He say "Jap soloon" is wrx consider a jap Soloon?
Anywhere u think it really fair to compare a mod car with a stock car ? and than keep slaming the stock car?
Anywhere dun u feel it out of porpotional to keep compare Wrx and the Sl500.. there are off different cls... -
handphone ni ki lan. Pin ponOriginally posted by jonathan_n80:SL65 also not bad.. quite a nice handphone.. anyone use it before?? -
quite true...YES they are performance cars but built for a diff purpose....the SL is like a grand tourer....just pour in the gas and the miles spew in effortlessly...dun think u can do that with a WRX....WRX is more like for blitzing down a narrow road....yeah thats what i thinkOriginally posted by zheshi:pls Read the first post of this tread before u question me back... if u want to be so caluative ....

is the rex made in japan? yes.Originally posted by zheshi:pls Read the first post of this tread before u question me back... if u want to be so caluative ....

is the rex a 4 door car with a protruding boot area? yes.
so it the rex a jap saloon? duhz......
anyway, i dun care if we are comparing cars in different categories. if big mags like top gear can pit cars like the evo FQ 400 against the lamborghini murcielargo for a performance caomparison, i dun c y we have to adhere strictly to a comparison dictated by u on a public forum. besides, do u still question the fact that this topic IS talking about modded japanese saloons vs stock continental sports cars? -
true... but 911 Turbo for me!Originally posted by AE86tofu:heavier than the SL55....no thanks....sl55 has the right balance of power
