Yesterday i went to the scooby shootout and my mate followed me there and back, he has a mini cooper S, the super charged one. i know he has had a smaller pulley put on the S charger and he says it puting out 197bhp, but could i pull away from him in a straight line could i hell. I would,nt say it was any quicker than than the scoob but there was no getting away from it.
I was driving my 05 sti.

197bhp v 264bhp and you're a lot heavier, why are you suprised?

wwp8

yep well said by the pug man himself

go on a diet

Karl-AL

i just thought that cause i have more power i should of been quicker but i didnt think of the weight issues

Gutmann pug

Weight makes a massive difference. I would rather my car lost 100KG then had an extra 30bhp.

Out of interest then how much faster would my WRX PPP be 0-60 if I was to go on a diet and lose 20kg ?

If you work it out, I think these figures are accurate:

Impreza STI 05
Weght: 1480 KG
Power: 261 BHP
Power to Weight Ratio: 176 BHP per metric tonne

Mini S
Weight: 1215 KG
Power: 197 BHP
Power to Weight Ratio: 162 BHP per metric tonne


14 BHP different, not much in it really!

Gutmann pug

Well the clio cup is about 1/2 second quicker than a std 172 with 100kg loose so I reckon 0.1 second with 20kg

Gary

Bartop

Thank god for that - 9 months of misery for 0.1 seconds, not worth it

I think I'll put off that diet for another day and get a sports cat and remap instead

Just to add a classic UK turbo into the mix for comparrison:

Impreza STI 05
Weght: 1480 KG
Power: 261 BHP
Power to Weight Ratio: 176 BHP per metric tonne

Impreza UK turbo standard (classic)
Weight: 1235 KG
Power: 218 BHP
Power to Weight Ratio: 176.5 BHP per metric tonne

I think it'll be even more telling if we compare BHP at the wheels; I'd guess the scooby looses much more than the mini?

I recently test drove a Mini Cooper S Works (210 BHP) and it was fantastic May buy one soon but am waiting for the Mitsubishi Colt Evo to come out

Let's get some objective figures on the table, before people in Mini's get carried away too much (although I think they're fab cars). People quoting power to weight figures without taking gearing and transmission losses into account is a complete waste of time and tells you practically nothing about how the car will feel performance-wise.

If you calculate the power at the wheels in each gear, taking account of gear ratios for each car, make an adjustment for weight (i.e. power to weight at the wheels in each gear), plus make a final adjustment for transmission losses (say 25% for the scoob, 15% for the mini), then you get:

1st number: Std STI - 261bhp
2nd number: Mini Cooper S - tweaked - 197bhp

1st: 1876, 1700 (91% of scoob power)
2nd: 1225, 1036 (85%)
3rd: 908, 75 (83%)
4th: 694, 613 (88%)
5th: 501, 509 (102%)
6th: 390, 416 (107%)

So...on these rough figures...std sti has more power available at the wheel in 1st to 4th, but in 5th and 6th this modded mini actually has more power at the wheels (based on my very rough transmission loss assumptions, but probably not miles off) - not too much of a surprise, as 5th and 6th on a UK STI are overdrive.

Either way, it's within 18% of the scoob's power whatever gear you're in, so one fluffed gearchange is all it's going to take to mean this cooper will stay with the STI. However, it ain't faster, however you cut it.

Edit to say: a 210bhp works car gets even closer - same power at wheel in 1st, a little lower 2-4, then quite a bit higher 5th and 6th. All I can say is mate, get yourself the PPP kit!

My missus has got one. Most fun I've ever had for £16k!

mattvortex

try a clio182 cup and have even more fun for about £12.5k

Karl-AL

i think i will have to get the ppp now my mate is still taking ****, so i will have to do something to shut him up.

furrydice79

i had an 03 cooper s before my MY05 sti , i kinow my car didnt have the smaller pulley but by god is my new car soooooo much quicker , a coop s wouldnt stand a chance

RB5 Paul

My misses might be in a draw at work to win a brand new cooper s,anyone want it????
I'm either gonna sell it or set fire to it haven't decided yet,money would be nice but would it have the same satisfaction as burning it????

I had a play with one of these on the motorway for about 2hrs, in my last scoob a MY99. It was one of the competition cars to, as it was fully decked out in sponsors gfx, had the rollcage, electric cutoff etc etc. I could get away from him quite easily, and he was definately trying. He always caught up due to heavy traffic. I guess I was able to do this over an STI due to my mighty power to weight ratio advantage of .5bhp
