don't know abt the Impreza in ctg, but the Dodge Charger might have 450 hp.......cause I think the 70s Chargers usually came with 325-450 hp in stock. now hp of the charger in BD depends on what model the charger actually is......if its the top of the line Charger, then it might have 450 hp.
btw, the ideas u gave are not bad either to test the acceleration and power and all that......but its time consuming.....i mean who would go around and test so many cars? well, the stock car's hp that we know abt....like the M3 or Cayenne Turbo doesn't really need to be tested.... we know how powerful they are and what things they can do...I would rather suggest to test the modified cars.
btw, post ur Impreza pics in the Gallery. would be a nice treat. Is it the STI?

alright alright...I know the pics are overdue ! I'll get them posted this week. :)
Regarding one guy going around testing all the cars, we don't need to do that unless we have a sort of get together where we test a few cars. Instead, members can just post in their own times tested by a friend of theirs. Ofcourse, we would be assuming that members are honorable with regards the data they would be submitting ! If things take off from there, at a future date we can look into testing some of the cars as a group to get "official" verified times. I'm sure something can be arranged if we seriously work together as the drivetime "club". It would also be good to test the standard fast cars - their figures will provide benchmarks by which all others can be judged. Anyway, just an idea.

How clever of you Tawhid ! Haven't timed my car yet. Will try this week and let you know when done. But, I can reveal I had a race with a blue EVO 6 about two weeks ago. He was with me for a few seconds. But, when I hit 170 kmh on the speedo and looked at the mirror I saw him trailing about 8-10 car lengths behind and eventually backed off from following me. I don't know if there was something wrong with his car, but he was very serious initially.
Having said this, I must add I'm not into racing other cars on busy roads. However, i can get carried away on long comparitively empty stretches at off-peak hours !
By the way, my car is not an STI, but is modified from original. In stock form it had 260 bhp. Now it has a 2.5lt engine with a bigger turbo and other engine mods. I don't know what output it has, but, I know it's faster than the regular STi that has 280 bhp in Japan and the rest of the world and 300 bhp in the 2.5lt US model.

you got the power to weight ratio just right, it would be a close fight thoughwrx wrote:So, someone can have a 500 bhp truck that weighs 3 tons (for argument's sake), but then could be overtaken by a car that has (only) 200 bhp and weighs just a ton.

The blue evo 6 used to be serviced at a local garage in kakrail a few yrs ago. The mechs who were working on the car shortened the valve spring in the dump valve, because they thought it was a leak. It was a tragic sight watching them ruin the engine. Anyways i heard the owner sold it, i presume it hasn't been replaced.wrx wrote: I had a race with a blue EVO 6 about two weeks ago.

The last I heard about the EVO 6 was that it was once being test-driven by the General Manager of the Rangs Mitsubishi workshop (who is now a Director of Rangs) and during the spirited drive it blew a piston. I asked the GM if it was true and he confirmed the incident and also said that the car was was fixed after the required parts were imported.
I also heard that the car was imported by one of the brothers who own Gazi Bhaban (who has a stake in the showroom "Car Dream"), and he tried to sell it through a car showroom in Kakrail but could not be sold. At that time the showroom was asking for 40+ lacs for the car. Since it could not be sold, I was told the importer has kept the car for his own use. My own office is in Naya Paltan on the 9th floor (my room facing the main road), and I see him zooming down VIP road sometimes, that is, when I am looking out of the window !

wrx: loved reading your posts. you sound very knowledgable........which is great. you rightly said that japanese cars are tuned for RON 100 which equals to RON+ MON/2 (93 octane) in the US. Bangladesh though, we cant say for sure what the octane ratings are. Last i heard from a very reliable source (Mr. Shahed of Gulshan petrol pump) that we get RON 90 in Bangladesh, which btw is crap for turbo charged cars.
BTW i thought domestic they didnt make 2.5l. Where did you get ur engine from: the UK??
Whats ur setup??

Thanks for the kind words rxse7en. Your're right, they don't make 2.5lt for domestic models. My engine was taken out of a subaru legacy export model, the heads are standard, but the block has been rebuilt and all the internal parts have been changed with uprated parts. Forged pistons, ARP head studs, steel crank, billet rods, copper head gaskets, heavy duty bearings, piston rings and pins, the block has been re-inforced, etc. Built to easily take 30 pounds of boost. Also, bigger fuel rails, fuel pump taken from the Audi RS6 twin turbo, 650 cc injectors, etc. Heavy modifications. But, that's all I'm willing to reveal about the specs on the net.

At last, I've managed to upload some pics ! You've waited a while. Hope you all aren't disappointed !!
Tawhid, you wanted to know my 0-100 km/h time. I have timed the rolling 5-100 km/h. It came up at 5.38 sec. Based on this, I can calculate the 0-100 km/h to be about 3.68 sec. Means of deduction as follows.
The US published "Car and Driver" magazine, in their Feb 05 edition, road tested the 05 Evo 8 MR version and the 05 Impreza WRX STI. The Impreza has a 2.5lt 300 bhp engine, while the EVO has a 280 bhp 2lt engine.
In the rolling 5-60 mp/h test the Impreza took 6.4 sec. On the other hand, in the 0-60 mp/h test (high rpm launch) the car took 4.9 sec. That means, that a high rpm launch gave the car a 1.5 sec advantage (because of traction quickly gained by the awd system). As my car is even more powerful, it could be assumed that my car should at least match the advantage of 1.5 sec in a drag launch. On top of that, for 100 km/h (62 mp/h) it would take an additional 0.2 sec (?). So my car should take 5.38 minus 1.7 = 3.68 for 0-100 km/h. I could also add that I had an extra passenger in the backseat holding the stopwatch, while the cars in the test had only the drivers. The extra weight could cost a couple of tenths of a second. In comparison, the Evo took 6.3 sec in the rolling 5-60 mp/h and 4.8 sec for 0-60 mp/h. But beyond 120 mp/h, the Impreza took over.
The reason I did not go for a drag style launch is that while my engine is modified, the gearbox is still stock. From Impreza forums and from major tuners I have learned that the stock gearbox cannot take the increased torque of the 2.5 lt engine. Harsh shifting will break the box and a 6000 rpm launch off the line is a definite no-no. So, for drag launches I need to change to an uprated box, which I will be doing later in the year (unless I break my box sooner). I could be wrong in my calculations for 0-100 km/h above (especially, if there is speedo error), but I'll try out a drag launch once I have the new g'box fitted and get the time posted. By the way, I was running only 16 pounds of boost, controlled through an electronic boost controller which has 3 boost settings - 16 pounds is the lowest. It goes upto 30 pounds of boost, which is only recommended when very high octane race fuel is used.
I admit, the estimate sounds incredible, but not impossible, when you know Mitsubishi claims 3.5 sec to 60 mp/h and 9.1 to 100 mp/h for the 405 bhp Evo 8 FQ400, which is only overtaken by the Lambo Murcielago in a straight line after about 200 km/h.

a little correction.......in the car and driver mag.....the STI made the 0-60mph in 4.6 secs and the 5-60 mph in 5.8 secs...so calculate ur 0-100kph or 0-62mph again.
btw, how did u make it that fast? cause usually cars run that fast when they are tested with highly experienced test drivers......moreover car acceleration depends on the climate, road condition etc etc.....even other magazines like motor trend or automobile don't get the times that car and driver gets....C/Ds tests numbers are always better than other magazines...and cthey tests their cars on tracks....which are smooth like ice cream......how did u make it that fast in Bd roads? without any doubt Bd road conditions can't match track conditions.
then again, the STIthat the C/D tested was a 2005.....prolly a brand new one as well...or may be with very low miles.....urs on the other hand is the older version WRX.......and prolly has couple of thousands of miles on it...so the performance should definitely differ from the newer ones...and u said ur gearbox is stock.....so the older stock gearbox shouldn't perform as well as the newer ones.....
ever tested ur hp? must be riding a 500 hp wrx.....otherwise going that fast with all those performance decreasing conditions sounds impossible to me.

wrx: r u running an external wastegate?? or is ur stock one ported?? Another question i had was, how exactly did you tune your car?? We have no dynos in Bangladesh. How r u so confident about your A/F ratio?? How do you know that it doesnot get lean in the higher RPMs. I know that you have a upgraded fuel system, but with the quality of octane here in Bangladesh, how much pinging and knocking can the engine withstand with even 16 pounds of boost. Do you have a wideband 02?? What ECU are you running?? Electronic boost controllers wont do much, unless you have uprated your wastegate.
Please dont misunderstand me here, i'm not posing them as negitive questions, i'm just eager to learn. Reading your posts i can understand that you have done your fair share of reseraching the scooby forums. The setup surely sounds incredible, props to you.

Zoheb, I stand by the Car and Driver figures I have quoted. The article starts on page 60 and the performance figures are given on page 66. I know, because I have that edition of the mag in my home in Dhaka. Regarding my horsepower figures, my tuner told me I would make 600 bhp (flywheel) at 30 pounds of boost. Less than that, of course, on less boost. It is tuned for 91 Ron Octane - like in the US.
Regarding stock box, that is a major gripe of mine (as is the soft suspension). The gearchange is very slow and balky. That's the next thing on my shopping list.
Regarding them being new cars, you are right. But, my engine is new, has only 1500 kms on it.

i don' know which edition u r talking abt.......but the car and driver's site says the numbers i mentioned above. here is the lil part from that article....wrx wrote:Zoheb, I stand by the Car and Driver figures I have quoted.

"But there it is: a sprint of 4.6 to 60 mph, 0.4-second faster than the Mitsubishi and a figure that's going to be hard to achieve in any car near the STi's $31,520 base price. Our 5-to-60-mph street-start sprint of 5.8 is a more realistic, less-abusive gauge of real-world acceleration. It's all accompanied by a tough-sounding midrange trill of an exhaust note."
